Sorry, I found this very funny. I assume that he and his party have realised the double entendre, but I just can't help but know that if he took the reins as the US President, he would be taking the US even further to the right, hence yes he would bring 'right' change. I know that debates about his conservatism have ranged around the block. Only time will tell. I just hope he doesn't get the presidency.

Have a look at Dani Rodrik's blog where he discusses some opinions on the recent growth phenomenon of several African Economies, specifically linking it to an article by Ted Miguel. He links his discussion to Randomized (Impact) Evaluation, something which I believe is a very useful tool for development economists and should be used more for understanding what could work in SA specifically in terms of development policy.

As he emphasizes, what is becoming clearer and clearer is that:
1) finding out what DOESN'T work is very, very useful. This is something for which RE is particularly good (and which stops random politicians trying stupid policies that have been shown not to work)
2) what is often required for development is adherence to a set of ideas about how to attempt to implement policy rather than necessarily what the policy should be

Rodrik is somewhat sceptical about RE and has written an article about it. I will report back after exams on his academic article and on the Miguel Article. On Miguel he has done some really good work, and some really arb work. I saw a working paper of his recently, which was presented by a co-author from EUI at a UniSi seminar and I wasn't particularly impressed, but hey everyone has their ups and downs.

So, I am fully behind the win of Barack Obama. Interesting comments, from Time, the NYT and other places.

Here is a link to the video of his victory speech.

Otherwise, Silvio Berlusconi is troubling people with his doublespeak on immigrants. What's that you say Silvio? They aren't illegal, even though you passed a law that they are? Are you realizing that illegal immigrants are necessary for Italian growth? Ohhh... the cheap labour of it all...

And otherwise, hat tip to Mike for recommending another interesting TedTalk to me. Here it is for those of you who are interested: fun discussion by Susan Blackmore.


As Mike himself comments, it's really difficult to assess universal Darwinism and some of the assertions that she makes could be quite easily disputed. Have a look at Mike's blog to see some good comments.

So this week is going to be crazy busy. Arthur Robson, of Simon Fraser University, is coming to visit as the new Bioeconomics Chair at St. Chiara College, of UniSi.

I am also meeting up with Bob Rowthorn, from Cambridge, to discuss some of his interesting recent work on slow learners and possible paths for my PhD. He is a really interesting and bright guy, and I enjoyed meeting him previously in Barcelona. You may recall that I blogged about some of his work previously.

Erik Olin Wright, from Wisconsin, is also coming to present some work here on Thursday. Luckily that's after my Macro exam, so I'll be a bit tired, but looking forward to it nevertheless.

Yes, I write Macro 3 this week. Joy. Such great seminars and fantastic people to meet, who arrive while we write exams. Oh well... less study time then.

As most of you know by now I am a proud supported of complexity theory in economics. There are several recent articles that you can look at on this topic:

A Brave Army of Heretics, David Warsh, Economics Principles
John Horgan on "Can Chaoplexology Save Economics?", by Barkley Rosser
Can Chaoplexity Save Economics?, by John Horgan

Hat tip to Economist's View for two of these links.

I'd also recommend Barkley Rosser's homepage for a number of papers.

A number of books, Eric Beinhocker's Origins of Wealth and one of the original sleuth style books giving coverage of the development of the Santa Fe institute is Waldrop's Complexity, give them a look if you have the time and money.

I just wanted to recommend that people take a look at this post on Marginal Revolution. I have blogged a few times about many of the eastern countries' practices in terms of managing to improve science graduation at high school and later in university. The paper on which the MR post is based reiterates how important this has become, how China has graduates soaring into the sciences and engineering and how this will impact on future innovation and China's ability to have an impact on the world economy. It is truly astounding. I just wish that the SA govt would think about it a bit more and get its grip on high school math and science.

Two days ago Joseph Stiglitz gave a lecture here at the University of Siena for the Workshop Benessere e Imprenditorialità. It wasn't intended solely for economists and as such was often quite superficial and cursorily dealt with some of the issues that he was trying to promote. This was quite sad for me as I have often enjoyed and appreciated what he has written in Economics and I was hoping that he might have make some more rigorous arguments for the promotion of Corporate Social Responsibility (CSR) (one of the themes of the talk) and its link to generalized welfare.

His talk covered CSR mainly in reference to three themes:

1. Conduct in the recent credit crisis in the US and its movements worldwide

2. The role of business in climate change and sustainability

3. The misuse of GDP as an index for measuring welfare.

Each of these has several different implications in respect of world trade, international relations, the functioning of credit markets and so forth. I will try to comment on each of these (now and in later posts).

First, in terms of the credit crisis, there is now a fantastic amount of commentary on how this has permeated from the US into the world economy. I don't think it's particularly worthwhile for me to comment on that (check the Economist's View blog for good coverage of this and other topics). A point that he has made, which I think is particularly relevant, is that corporate social responsibility is not simply the fact that government needs to regulate companies so that they do the 'responsible' thing. It requires buy-in (yes, hand-wavey I apologize) from the companies themselves. Stiglitz gave the example of a Chinese company (which he couldn't name) asking the government to regulate the industry and suggesting specific regulations. The CEO of the company's argument was that if their company wanted to be both profitable and responsible it needed to inform government as to the types of regulation that are required. Why? Because if they are a profit-maximising company and they are competing with privately owned (unlisted firms) that don't have similar systems of reporting, etc then govt needs to insure the economy against malfeasance by these privately owned firms by regulating both privately owned and publicly owned firms. Why again? The publicly owned firms would lose competitiveness against the privately owned firms if the privately owned firms pollute, mismanage labour, etc. Hence, it is in the publicly owned firm's interests for it to promote regulations to ensure corporate social responsibility of all firms. However, this will obviously be 'tainted' by the extent to which this is in the interests of the publicly owned firms. In my mind there is a further asymmetry of information, that which exists between the publicly owned firm 'acting in govt's interests' and govt itself. Obviously the public firm wants to be competitive, in fact it would probably suggest regulation that it, as a larger and public firm could probably easily internalize, whereas the smaller private firm may not be able to. He didn't mention this and I think it warrants comment. Especially because so many private SMMEs are necessary for us to increase growth and employment generally. So yes, it is good for corporates to cooperate with govt, but govt needs to be equally sceptical of their 'input' and must, absolutely must find a way to regulate all firms in such a way that is sensitive both to the firms and to the needs of govt.

Stiglitz contrasted the above Chinese example with financial corporations and their interaction with govt subsequent to the credit crisis. Thes companies are arguing, still, that they DO NOT REQUIRE MORE REGULATION! What? Are these people insane? Have they not noticed the credit-crunch? Have they not seen that (literally) millions of Americans are losing and will lose their homes on account of the speculation of these companies and yet they say they are over-regulated? Come on!Moreover, that these companies have CEOs who walk away with incredible packages at the end of the year, while the average customer is walking away without their life savings and having lost a home is incredible (more on CEO remuneration later). He comments further that companies such as Citibank, with advertising campaigns saying 'Qualified at birth', or companies sending credit card forms to fourteen year-olds, is a form of indentured labour. The companies get the individuals into debt quickly and then keep them paying back the loans for the rest of their lives. Oh yes, on the above topic, don't even let me comment on George Bush's plan to veto the house's proposition to alleviate the pain caused by the credit crisis. Once more he is funny in the head.

Stiglitz also accurately commented on two different Business School and Corporate type supposed 'movements away' from evil profit maximising. Firstly, 'shareholder value'. Well, I'm not going to go into this one again with too much detail, but maximising shareholder value does almost nothing for ensuring the long-term value of the firm because the CEO and the firm generally become far too sensitive to short term movements in the market which may have absolutely nothing to do with the activities of the individual firms. Consider the market at the moment and food shortages, a decent analogy can be found in the various reserve banks being unable to control inflation internally because of the fluctuations in food prices internationally. It would be foolish to expect the individual reserve banks to be able to curb inflation in their own countries when core inflation is up so much. Ditto shareholder value and random fluctuations in the market. Stiglitz argued that shareholder value was actually doublespeak for maximising managerial wealth. Why does he argue this? Well, the US has actually had decent economic growth in the past 9-10 years. Has the 'ordinary American' gained anything from this? No! Real wages have not increased for the average worker, the benefits of from growth in the US economy have gone almost entirely to the top 5% of income earners (or even top 1%). CEOs take away massive remuneration packages at the end of each fiscal year. Stiglitz argues (again accurately in my opinion) that this is another area that CSR needs to tackle and in which govt needs to intervene. CEOs cannot continue to be the only group to benefit from growth in the economy, assuming that there is any growth after the recession created by overly risky loans.

Ok. that's enough for now. More later on Stiglitz and some of his suggestions.

Subsequent to my post two days ago on the Herrmann, Thöni & Gächter paper, Simon Gächter presented some more evidence at the Faculty of Economics. Having already heard some of the stuff before I was able to think about it a bit more and to think contemplate some of the additional repercussions of the work. Moreover, because we sat there for about two hours talking about the paper and the evidence, the contributions by several individuals increased my understanding even more. Fantastic times.

Anyway, one of the things I don't think that I gave sufficient weight to previously was the way in which this evidence directly contradicts the rational actor model. To me this has become almost trivial, but in interacting with others I regularly become aware how pervasive this view still is – the view that in order for us to have coherent economic theory we cannot deviate from a rational actor model, with regular preferences that are entirely self-regarding. Individuals preferences are evidently not entirely self-regarding. There is a surfeit of evidence to show this. Moreover, that something as ephemeral as 'culture' could actually enter into the ways that individuals behave is entirely contrary to the way in which economics operates, or, I should say, assumes individual agents to operate. Thus, the evidence that I discussed which Herrmann et al. found from their experiments is rather quite exceptional. It illustrates definitively that different cultures will act differently in situations of economic cooperation.

Subsequent to these experiments Gächter undertook further experiments in Switzerland and also in Russia. Once more the evidence there was anti-social punishment in Russia and the exceptional 'punishment results in cooperation' result in Switzerland. However in this set of data the sample in each of the countries was much larger than it had been in the inter-country comparisons previously. The samples covered rural and urban, mature and young. The anti-social punishment norm was pervasive in Russia, in Switzerland it was non-existent. This is astonishing. It provides evidence, once more, that conventional models in economics, i.e. the neoclassical Arrow-Debreu-Koopmans models I mention above are entirely inadequate to describe the behaviours of agents in modern day economies. I believe too that this kind of validation was necessary in order to show that their data wasn't simply quirky. Moreover, Benedikt Herrmann in personal communications, recently told me that experiments done by a colleague of his in Africa (though I hate that generalization) have had similar and particularly strong anti-social punishment results.

Moving away from these considerations, Gächter links the phenomenon of antisocial punishment to some of the (very) recent literature on 'Do-gooder derogation' (Monin, JPSP, 2008). The kind of situation where cooperators, or 'do-gooders' are sanctioned by others because these others view their behaviour as paternalistic, condescending and 'better than thou'. I haven't read Monin's paper yet, so I cannot comment on this, but my suspicion is that this may be accurate. Furthermore, when Gächter discussed indexes from Hofstede (I think) referring to individualism vs. collectivism, it was shown that those countries in which the individualism ranking was high and the collectivist ranking was low were less likely to anti-socially punish others than those in which the individualism ranking was low and the collectivist ranking was high. I think there may be a few factors endogenous to this though, as in their data their was a fairly strong correlation between lack or rule of law and lack of civic norms with the low individualism and high collectivism indices.

Speculation
It would be really interesting, imho, if we could somehow manage to control for various factors and say 'this is the marginal effect of the norm'. Don't think it's at all feasible, but it would still be interesting. Would this norm (dummy?) variable be something like the controversial 'Africa Dummy'?

More on this and other topics soon.

Herrmann et al. Cooperation and Antisocial Punishment Today's comment (probably the last one for a while depending on time and studying) is about the (2008) paper by Benedikt Herrmann, Christian Thöni and Simon Gächter in Science.

The main thrust of the paper is to do with what the authors label as 'antisocial punishment', i.e. punishing those people who are cooperating in a public goods game with you. This is contrary to most of the literature on the subject in which punishment normally ensures that players in public goods games end up at a Pareto superior solution of cooperate (most of the time).

The authors undertook 16 sets of experiments in 15 different countries (you can see the countries in the graphs). The authors then look at some specific reasons as to why the results could indicate such strange results for the different groups in the different countries. They argue that social norms (social preferences?) could exist which would promote specific patterns of behaviour rather than others. Thus they try to use an instrument for civic cooperation in society, which might be indicative of the necessity to punish free riders in order to display that such behaviour is unacceptable. However the converse, that low civic cooperation necessarily leads to antisocial punishment is not necessarily true, but they try to test the thesis regardless. To test this hypothesis they use the World Values Survey, The second hypothesis is that strong rule of law could lead to a situation in which personal revenge punishing, or antisocial punishment would be unacceptable – 'effective, fair, impartial' legal institutions could erase the need to personal revenge punishment (this is supported by an interesting, if slightly more anecdotal article by Jared Diamond in the recent New Yorker). To test this hypothesis the authors use an law indicator provided by the World Bank. Norms of civic cooperation were important in determining punishment in ensuring cooperation, but rule of law was not significant. With respect to antisocial punishment, better norms of civic cooperation and improved rule of law would decrease the likelihood of antisocial punishment. Stating the converse – countries with poor rule of law and low norms of civic cooperation were more likely to have antisocial punishment. Anyway, taking note of these conclusions, I think it is quite cool to have a look at the graphs. The first graph is the graph indicating whether cooperation occurs when the punishment option is not allowed, i.e. this forms the control group against which the punishment group is compared.

As is normal, we see that the groups start off cooperating, but then basically move downwards. However, what is astonishing is the disparate starting positions for the different cities and the different end positions. Normally, one would expect 'first world countries' (high civic cooperation, high legal institution quality) to have decent cooperation in general. This is not the case, for which Melbourne, Australia is the most interesting exemplar. Istanbul, Riyadh and Athens are however very near the bottom (and stay there in the second graph). Copenhagen has very high norms of cooperation, with cooperation being high in this graph and also in the second. In the second graph (where the experiment is run with the option to punish) we observe a massive change in behaviour for certain developed countries, again Melbourne is interesting as their behaviour has come into line with most of the other developed countries, but is not as high as Copenhagen or Boston.

Something which is fascinating to see when assessing the graphs side by side is that the behaviour in Minsk, Athens and Riyadh (and to a lesser extent Muscat) is almost exactly the same in the control as it is in the punishment treatment. This is quite astounding when considering the evidence that is normally offered in this literature. I think that this warrants substantial additional research. What makes the second graph particularly interesting is the variation in the final outcomes. In the first graph there was some variation (difference max-min = 7.6 units), but the shape of the curves was fairly similar for each of the societies. In the second graph there is dramatic variation in the outcomes for the different societies (difference max – min = 12.3). These are very rough, I admit - I don't have the data set, but I encourage you to read the paper for some more direct and applicable analysis of the dataset. I would also intuit that if you looked at the averages for the two groups Chengdu up to Boston against Minsk down to Athens you would get a significant difference between these groups, whether these groups deserve aggregation is something worth checking in terms of the civic cooperation and the legal institution index.


One additional comment I'd like to make is that I think that this kind of research would be especially worthwhile in both South America and Africa. The sample at hand covers groups from the US, Europe, Asia and Austalasia. It would be cool to see a couple more from the Australasia/Oceania region too, but I think there should be some experiments done in South America and Africa, as already stated. These would face additional and particular challenges, but are warranted nevertheless.

This post is a comment on the paper by Rodriguez-Sickert, Rowthorn and Guzmán (2008). It was the basis for the presentation given by Bob Rowthorn at the TECT/SOCCOP meeting.

The main theses of the paper are centred around

1. Genetic algorithms for specific behaviours

2. Learning algorithms again for behaviours

As is customary, it is assumed that individuals payoffs are not only a function of their own actions, but of the actions of others. Thus, if one individual is a defector and they interact with (are randomly paired with) a defector/cooperator/cooperator-punisher then their payoff is modified accordingly. The idea of 'learning' models as follows: individuals adopt the learning model of their parents, although this is open to mutation. Individuals therefore have one of three possible learning modules:

1. Conformism (copying the most common behaviour in their tribe)

2. Payoff-dependent imitation (copying the most profitable behaviour)

3. Best responder (homo economicus)

Individuals use these rules in order to choose whether to adopt defection/cooperation/cooperation & punishment behaviours in the relevant interactions that they face. Implicit in these learning algorithms is the belief that access to information is costless. Individuals cannot 'hide' their type. This paper is more about the description of the prevalence of behaviours than the arguments about costliness of behaviour and of arguments about encephalization and brain size. Each of the strategies could be argued to be costly in some manner, the level of the cost is relevant in other models.

The model is based on descriptions of hunter-gatherer society available in Bowles and Choi (2007) which it uses as starting conditions for the society. There are T tribes, each of which have constant and homogeneous size N. There is migration between tribes (through exogamy) and tribes go through cycles of (ritualistic) behaviours: hunting, war, reproduction, migration and learning (individuals interact and gain the strategy of their mentor with some probability, or they 'innovate' and get a strategy that neither agent has, innovation only applies to payoff-dependent agents, not others). Personally, I think that migration should come after war and before reproduction, but I could be wrong.

Selection pressures act at two levels: the within-group level (individual agents maximising their fitness) and the group level (tribes interacting and determining which is better off). I refer you to the model for details, one detail that I mention though is the probability of a cooperator to defect, which I think is necessary. However, if there is a stochastic chance of a cooperator (or punisher) defecting, then I believe strongly that there should be a possibility of a defector mistakenly cooperating. This is for us to remain consistent with what we mean by 'mistakes', otherwise we are saying only that people who cooperate are capable of making mistakes, which I think is problematic. I don't really know how consistent this criticism is with the literature though. I am also not entirely sure of exactly how one would mistakenly cooperate, but can conceive of how one would mistakenly defect. Still not convinced though.

With respect to the inter-group interactions, the simulations that the authors run results in a baseline situation (discarding the first 50 000 years of interactions) of fairly stable percentages of the behaviours. Groups were paired randomly and do battle (the war stage). The group with fewer defectors is more likely to win than the group with more defectors (indicating the tension between within-group and between group selection). The battles are deemed to be 'massacres' with every agent in the losing tribe being 'killed' and replaced as follows: the surviving tribesman 'clone' themselves (rape of women in the previous tribe for example), then clones and remaining tribesmen intermingle to create two new tribes. One problem I have with this model is that it uses a random pairing method for interactions. I think that this is inaccurate and that in order for the model to make more realistic predictions tribes should interact on a spatial matrix and only meet tribes that are within a specific distance of themselves. This could have interesting results for the pervasiveness of specific behaviour patterns.

After the simulations, Best Responders comprise 5% of the population, Payoff-Dependent imitators comprise 20% of the population and Conformists comprise 75% of the total population. When the level of migration is increased to 50% then these percentages change, with Best Responders increasing to 40.5% of the total population, Conformists 38.5% and Payoff-Dependent imitators 19% of the population. Alternatively, holding migration constant and halving the conflict rate, the population consists of 15% Best responders, 60% Conformists and 25% Payoff-dependent imitators. Lower levels of conflict thus result in lower levels of 'cooperation'.

This paper is very interesting in my mind, mainly for the fact that it has a large number of groups (T=20) interacting over the time frame, which is quite good for this kind of work. I do think though that the spatial nature of 'real interactions' is quite crucial and that it could lead to high quality later work on the subject. I refer the reader to Bowles and Choi (2007) for similar work, dealing instead with parochial altruism. I think that a coupling of the two systems would be quite interesting, i.e. learning agents who could be parochial altruists (or altruists in other manners) and see what that might do to the simulations and to the models.

This first commentary will be on the paper by Edwards, Hassall, Sutherland and Y, Selection for protection in an ant-plant mutualism: host sanctions, host modularity, and the principal agent game, published in Proceedings of the Royal Society of Biology (2006) with some additional comments on the arguments Douglas Yu put forward at the TECT meeting.

The central arguments of the paper revolve around the observed facts that:

1. mutualisms evolve from antagonistic interactions,

2. and persist in the face of invasion by specializes parasites, and selection for cheating by the mutualists themselves.

I assess specifically the economic basis for the arguments presented by Edwards et al. and ask the reader to refer to the paper for the specific details offered on the experimental design, results, etc.

The essential points are the following, there are species of plants that have ant symbionts which populate the domatia that are produced by the plant. These domatia produce relevant benefits to the symbiont ant. Symbiont ants protect the plant from herbivory by investing in protection (a sunk cost), and thus maintain access to the domatia. Ants that seem not to protect the plant from herbivory (approx 10% of the ants that inhabit this specific plant species) that are found not to patrol (through some signal) will lose the benefit of the domatia. The argument is that this interaction is one that is customary to the principal-agent literature: there are two types of agents cooperators (protectors) and defectors (cheaters/non-patrollers). The idea is that the plant (the principal) will design a contract so that it can read the signals of the agents in order to know whether the agent is abiding by the contract. If the agent does not abide by the contract it is punished by the removal of the domatia on the branch that it did not protect.

Crucially, we must note several factors that affect how the ant-agents behave and how the plant-principals act. The plant-principals signal their success by the number of domatia that they produce for the ants. The ant-agents signal their successful defence by ensuring that herbivory does not occur. In the context of the experiment, herbivory was simulated by cutting off leaves in the area where the ants patrolled the branches. These branches would then die off if a certain number of leaves were cut off (leaves cut = 4), but not for a certain lower number of leaves removed (leaves cut = 2). This would indicate that only 'gross misconduct/laxity' by the ants (i.e. something similar to the complete lack of protection offered by the one ant species) would result in domatia mortality.

The study found that a certain pertinent level of domatia (d=23) was the level at which selection between cooperators and defectors would be ambivalent. However, if the number of domatia exceeded this level then it is likely that protectors would be selected. This seems to be coherent with the data as the average number of domatia on the plants was 28 in the site under inspection. Consider this as a wage problem in the principal-agent setting. The principal needs to set some optimal wage in order for the agent to maximise their output. Moreover, the wage can act as a selection tool, reading the signals that are sent by the respective agents.

I believe that the paper offers a really high quality and interesting application of economic insights to the world of biology. Edwards et al. correctly assert that modelling mutualism as a market structure would be erroneous on account of the information asymmetries that would be present in such a market and the inability for the mutualists to have a 'complete contract' (me imputing economics to what they are saying). Thus the use of the principal-agent problem as a descriptive technique is almost certainly more accurate than that progressed by Noë and Hammerstein (1994) for markets in mutualisms. The economics that Edwards et al. use seems intuitively applied and theoretically well-grounded. Douglas Yu is currently moving this work forward by looking at other plant-ant mutualisms, as well as at fig wasp-fig tree mutualisms. The paper on that topic is currently a work in progress, but I look forward to its results, especially because of the fact that 'abscising' (cutting off) of figs in which excess oviposition has occurred does not seem to be a general pattern (if I recall his talk accurately).

As my previous post said, I was at a conference (actually a work group meeting) in Barcelona for TECT. TECT is centred around the The Evolution of Cooperative Trade. The group of which I was de facto a part because of Sam Bowles is called SOCCOP, which is again to do with the evolution of social and cooperative norms.

Over the next while I'll be spending some time blogging about the papers presented. I don't have the expertise to comment rigorously on all the topics as it was an interdisciplinary meeting. I will inevitably have my 'economic hat' on during the analysis.

The papers I'll be talking about are all available here. Most likely I'll have the first one up some time later today and the rest as I manage to read them while studying. I read some before the conference and will dredge up my notes on them too. As a point of foreshadowing, the presentations I enjoyed the most were probably the following:
Douglas Yu on the evolution of mutualisms (ant-plant, wasp-fig tree, etc)
Sam Bowles and Sung-Ha Hwang on Social Preferences and Public Economics
Bob Rowthorn on Slow Learners and Conformism
Simon Gaechter and Benedikt Herrmann on Evolution of Cooperative Punishment

There were several others that were really good, but these appealed to me personally the most. I may spend more time on them than the others.

I am in Barcelona in between my IO and Macro exams (we wrote IO on Tuesday, will write Macro on this coming Tuesday). Anyway, I am here on account of being invited by Herb Gintis (via Sam Bowles) to a workshop for SOCCOP. SOCCOP is a research program involved in attempts to understand human prosociality (and antisociality) in the context of evolutionary theory, economics, biology, sociology and so forth. It's a fantastic opportunity, which is why I am here in the middle of exams.

Anyway, Sandra Polania, my colleague from UniSi, and I left Siena yesterday morning on the 07:10 bus to get to Pisa airport. We then waited there for a few hours, me studying a bit of macro and listening to Richard Dawkins's The God Delusion audiobook on my ipod, interspersed with passages from the novel that I am currently reading, Bret Easton Ellis's Lunar Park. The juxtaposition of these on one another was interesting to say the least.

We caught our flight at 14:30 and arrived safely and uneventfully in Barcelona. I sat next to a mother-daughter couple who were having an argument about the daughter having possibly left the mother's bag back in Pisa. But seconds later they were getting intimate about fashion tips from the in-flight magazine. Entertaining. Arguments in Italian are such fun.

Sandra and I then caught the train through to Barcelona where we began our search for the residence at which Arcadi Navarro had told us we'd be staying. We got slightly lost, but thankfully with Sandra being Colombian she could ask the natives where to go in Spanish. I keep on thinking to myself, not ANOTHER language to learn... But it's next on my list after Italian and a brush up on my French. Ok.

After settling into our rooms and me attempting to lie down for a bit (left Siena with cold and headache, worse having arrived, lol). We then went for a walk down to the beach front. It reminded me of home (Cape Town). There we were walking along the beach front, people jogging, cycling and even roller-blading/skating and it gave me distinct feelings of home. It's somewhat like Cape Town, but simultaneously more modern and more ancient. It has the same cosmopolitanism. It has the areas in the middle of the city that are dead quiet, and others that are busily pumping. Fantastic. We grabbed a schwarma for dinner (cheap students that we are), sat beside the dock to eat and then made our way back to the residence.

This morning we both got up at a decent hour and spent some time studying for the pending Macro exam. I managed to chat to Amy on Skype, YAY! It is so weird travelling without my wife, rather difficult to explain, but her presence is simultaneously energising and calming, especially when I'm a sick little traveller. Back to Barcelona. After studying for some time, plus Skype chat Sandra and I went to the Parc Guell, by Gaudi. It was a very interesting experience, I felt like I was walking into a fairytale castle cum attack on modernism. Very odd. The pillars at odd angles playing with Classicism, the almost-kitsch collage tiling. That being said, I really enjoyed it and took some fantastic photos (sadly I left my camera cable at home, photos to follow once I'm back in Italy).

From there Sandra and I took a turn to the old city, wandering around and taking photos as tourists are wont to. We went to the particularly beautiful basilica, Santa Maria del Mar. It has a brilliant array of stained-glass windows, one of which I thought was especially beautiful (again photos to follow). We then took a crazily long walk home, go us for misreading the map! Anyway, I am now back at the residence and procrastinating. Well, I was procrastinating while writing this. Back to macro now...

Before getting on to this let me state the following for those of you who, for whatever reason, don't know it. I am (in no particular order and with no hierarchy of ranking) a 26-year-old, male, heterosexual, married, white, non-religious, South African man studying a PhD in Economics at the Università di Siena, Italy.

One of the things that I have wondered about for a significant period of time is exclusivity in movements. Specifically in activism surrounding race and issues of sexuality.

This morning I was reading this article from z-net about the LGBT movement and how young LGBT individuals see the movement and how they believe that it is misguided in its attempts (in the US) to be so continually focused on equal marriage rights for LGBT individuals. What immediately came to my mind is that, once again, I was reading an article about LGBT individuals, asking questions of LGBT individuals and why they thought that the LGBT movement was becoming unsustainable. There were no references whatsoever about recruiting non-LGBT individuals to the movement. None. Why?

In the article they also had this photo:
Subtitled: Queer youth march in Springfield, Massachusetts—photo from www.gbpflag.org

From which the question, "Where are the non-queer youth?" follows. Where are the non-queers who could be marching in solidarity?

I have marched against discrimination towards PLWAs (People Living With Aids), for rights to medication, for gender and race equality, and against abuse of women and children. All of these movements have, to some greater or lesser extent, identified some salient descriptor of my identity (semi-summarized above) and allowed me access to fight for the movement, to be active on the movement's behalf. However, when it comes to sexuality I have often felt, validly or not, that there was some kind of exclusivity about sexuality that I, as a heterosexual male (and therefore as part of the oppressing class maybe?) could not understand, or to which I could not relate in the LGBT movement.

Before I get onto this, I am going to relate some personal anecdotes and experiences. When I was at high school (a traditional, religious, single sex college) I was continuously labeled as 'gay', 'fag' and 'queer' (whatever these terms mean to adolescent boys) on account of being different: enjoying acting, singing in the choir, being able to dance, being liberal, being non-religious. I questioned my sexuality and asked myself repeatedly 'Are they right? Am I confused about liking women? Am I meant to like men?' These may not seem relevant to many LGBT individuals who do actually prefer individuals of their sex, but to me it was particularly worrying, was I wrong about what I liked? Did a number of conservative, homophobic individuals have some insight into my personality that I did not? Was I too queer to be straight?

Luckily for me, I ended up in Drama School for my first year of university (after a gap year). But the people at Drama School were equally prejudiced towards me, in a way different to, but not unlike, people had behaved towards me at high school. Individual homosexual lecturers ridiculed me when I wanted to play a rugby match, other individuals tacitly excluded me from social interactions because I wasn't arty enough, I didn't smoke marijuana and I dressed too preppie (when I thought about what I dressed about at all) and I really, really liked women. I was too straight to be queer.

Whereas in high school my behaviour was sanctioned because it was labeled as 'gay'. In drama school it wasn't 'gay' (again in a very, very broad definition of gay) enough. Now, I understand in hindsight that for numerous individuals who had recently finished school and who had wanted to leave behind individuals who played rugby, who dressed preppie, who were tall & sporty, these were weird reminders of things away from which they wanted to move. I was as symbolic to them of things that they disliked, or which they feared as I had been to the conservative, homophobic individuals in my high school (who were a minority I must actually state).

What I wonder about though is that surely instead of alienating individuals like myself the LGBT movement should be embracing us. When I was at university during Orientation Week, I would always stop by the stall for the Rainbow Society, the 'Gay and Lesbian Society' on campus. I once asked one of the representatives, 'What about hetero people?' the reply was that 'Oh, they're welcome too.' I wondered though how we were meant to know that.

So, if the same position still stands, both nationally and internationally, with respect to LGBT movements, how are non-LGBT people meant to know that they can offer their services, not only that, but that LGBT individuals actually want them to do so. When are we going to be targeted by your media? When are you going to be asking us to help? LGBT issues comprise an area that still requires momentous amounts of activism and that will require more in the future. I want to ask, am I as a white, heterosexual, married, male welcome?

Post Script:
For anyone interested, I stopped doing drama. I picked up Economics, completed a Bachelor of Social Science in English Literature and Economics, completed my Masters in Economics, then a Masters in Creative Writing and, as I stated at the beginning, am now doing my PhD in Economics.

So, I read a number of blogs and other things on neuroscience, psychology and economics. I also try to keep up to date, if I can, with little things going on in the Science world. Anyway, one of the things that piqued my curiosity was this article on Chinese-Indian cooperation in science.

The main thesis is that China and India collectively have about 38% of the world's total population. Moreover, they both have scientists educated domestically and internationally who are capable of improving their domestic scientific output. Both China and India are well aware of this fact. The governments of both countries are supposedly trying their best to ensure that as many as possible (though still not enough) of their compatriots who are educated abroad return home. Moreover, if they can achieve a state of cooperation in the sciences between China and India, then they will have a hub of software and hardware driven research that could rival the best anywhere. American isn't respected for much in China, but the article says that it is still respected for its science. While the US cuts back on government-based investment in S&T (according to the article, but not according to the NYTimes - it was cut last year in December, but a new budget for 2009 was proposed with a different agenda), China and India are promoting increases in government spending on both. Scientists in both countries hope that this will aid in the eventual peaceful resolution of political border antagonism between the countries. Who knows?

What is more important to me is that there are better ways to resolve political problems than we often consider. Moreover, there are also ways to try to increase progress in countries, and as a consequence speed up development, that do not require the sanctioning by government of the activities of individuals. What I mean here is that there may be intercountry antagonism (such as the Sino-Indian border conflicts) which may be circumvented and possibly prevented in the future by reinforcement of cooperation elsewhere. Which is very cool in my mind.

It reminds me how we need to get back on track in South Africa. South Africa, which was previously a leader as a developing country, is now falling behind numerous South East Asian countries that have invested far more in education and the sciences than South Africa has. (Which, if I remember correctly is in this paper). South Africa desperately needs to increase investment in the physical and engineering sciences. Not only this but high school graduation rates of mathematics (at higher grade), science and chemistry need to improve rather than continue on the downward spiral that has been seen (ok, this may be hyperbole). One of the things I worry about is that South African education officials state that education is improving, without noting how there aren't dramatic improvements in the sciences. Sadly, growth is not driven by the arts, or the social sciences. Growth is driven by entrepreneurship and the sciences. I don't necessarily agree with how the mechanism works (i.e. philosophically), but there is a fair amount of evidence to suggest that increased growth goes hand-in-hand with development in science and technology graduation rates (and also with the high school math and science grad rates I commented on previously). These aren't highlighted in everyday policy discussions in newspapers, though some do admittedly bring them up. Anyway, I could rant on about this more, but I'm going to leave it for the moment. Suffice to say that I don't think JZ would necessarily take cognizance of this and I don't believe he would surround himself with people conducive to such ideas. Intriguing indeed.

We took a walk down our road today. We try to do walks around and about our place every so often, so you'll get photos here and there. We were walking towards a place we were looking at for some friends to stay. It's quite a walk from where we are, but still on our road which runs all the way to Pieve al Bozzone (Hence the Strada di...).

Anyway, here are the photographs.




Amy, not as called as she might be, but looking over the fields toward the pond.


The road we had just walked, up the hill and over the meadows. So to speak.


A particularly enchanting tree, splitting down its middle.

3 Medium Melanzane (eggplants)

Coarse cooking salt

Vegetable oil

1 Large Brown Onion, chopped finely

2 Cloves of Garlic, crushed and separated (each clove goes somewhere)

3 Medium Tomatoes, chopped

400g Tin of Tomatoes, crushed

½ Cup Fresh Oregano

2 Tsp Sugar

500g Spinach, trimmed

250g Ricotta Cheese

1 Egg, lightly beaten

½ Tsp Nutmeg

½ Cup Grated Cheese

Cheese Sauce

50g Butter

2 Tbl Sp. Flour

1 ½ Cups Milk

1 Cup Grated Cheese

Cut eggplant into slices, place on a wire rack and sprinkle with the coarse salt. Leave to stand for ten minutes, then rinse, and leave on absorbent paper. After a further ten minutes, remove them from the absorbent paper and shallow fry them, in batches, in the vegetable oil until lightly browned on both sides. Drain them on more absorbent paper. I also used a bit of butter here, on the advice of Amy, which definitely gives them a nice bit of flavour. I didn't want to use too much oil for the shallow frying.

Cook onion and garlic until soft. Add the fresh tomatoes and cook, while stirring, until the tomatoes are soft. Add the crushed, tinned tomatoes, with all the juice; the oregano and the sugar. Note here that I didn't have any oregano, I added some dried oregano and some chopped fresh basil which was also really tasty. Leave this to simmer, uncovered, until it is reduced to half.

In the interim, clean and trim the spinach. Then boil until just wilted. We added a bit of bicarb and salt to the water when boiling the spinach in order to retain some colour. After boiling, squeeze off any excess water (Amy pressed it into our colander, which seemed to work well, they never tell you 'how' to do certain things in these recipes, How does one squeeze spinach properly?) chop the spinach coarsely. Combine the spinach, ricotta cheese, garlic and nutmeg in a bowl mixing it well.

To prepare the cheese sauce first melt the butter in a saucepan and stir in the flour until the mixture is thick and bubbling. Gradually add the milk, stirring the whole while. Once this mixture has thickened somewhat, start to add the cheese, stirring in slowly (don't just gooi it in). The recipe says to use Cheddar Cheese, but trust an Australian recipe for Italian food not to realise that YOU CAN'T GET CHEDDAR CHEESE IN ITALY! So you, we used mixed grated cheese, or formaggio grattugiato – basically Parmesan and others. It turned out really well.

Once you have prepared all of the above, oil a decent oven-proof dish and use 1/3 of the eggplant as a base layer on the bottom. Then pour the tomato and onion mixture over this. Make a second layer of eggplant, which you cover with the ricotta and spinach mix. Add the remaining eggplant as a final vegetable layer and cover this with the cheese sauce. Sprinkle some cheese on top of this. Bake in the oven for about 30 minutes, until it is light and golden on the top.

It makes a fantastic main meal, or complements other meats nicely. We supplemented it with a good bottle of Chianti that I was given as a gift for proof-reading some stuff as a favour to one of my classmates: Conti Serristori Chianti Classico. What fun! Hope you enjoy the preparation and the food itself as much as we did.

Apologies for the second blurry picture. We were being silly and didn't check it. Also, we have no control over our heinous wine glasses, they are part of the package in our semi-furnished home.

I have long wondered what specifically makes an individual economist the way that they are. An associate of mine back in Cape Town, Mandisi Majavu, made me aware of this paper and I was wondering what others thought of it. It's called The Making of An Economist Redux (JEP, 2005), by Prof. David Colander and comments on a number of the top graduate schools in the States. Thoughts? Opinions?

You can get the paper at this link.

And also, for those of you who care, you can see in this Q&A from Freakonomics at the NY Times that Hal Varian uses Linux.
