A Study in Child Cooperation: Sweden vs. Colombia


The behavior of children continues to be of interest for both economists and Freakonomics. Back in May, we looked at research by the German economist Martin Kocher showing that young children are generally less risk-averse than adults. Now, a working paper by Juan-Camilo Cardenas, Anna Dreber, Emma von Essen and Eva Ranehill at the Stockholm School of Economics compares the cooperative behavior of Swedish children and Colombian children using the Prisoner’s Dilemma game, which explores how two parties cooperate in the absence of communication. Here’s the abstract:

We compare how children aged 9-12 in Colombia and Sweden cooperate in a Prisoner’s Dilemma. We introduce a new measurement device for cooperation that can be easily understood by children. There is some evidence of more cooperation in Sweden than in Colombia. Girls in Colombia are less cooperative than boys, whereas our results indicate the opposite in Sweden. Girls are in general more cooperative with boys than with girls. Relating cooperation to competitiveness, this appears to be task and country dependent.

The authors aim to explore how preferences regarding cooperative behavior are formed, given its important role in maintaining a functional society, and the interplay between culture and gender. From the paper:

We find evidence of children in Colombia being less cooperative than children in Sweden. This is mainly due to a significant difference in cooperation between girls from the two countries. Girls in Colombia are less cooperative than boys, whereas our results suggest the opposite in Sweden. We find some impact of the gender of the opponent, with girls being more cooperative with boys than with girls. Correlating behavior in the cooperative task and the competitive tasks, we find different results comparing girls from the two countries, but these correlations are not present in all tasks. There is no evidence of a correlation among boys.

    My takeaway from this is that women take their cues from society moreso than men, the canaries in the coal mine.

    I’m not surprised, sadly. I’m a Mexican living in Canada and I see fundamental differences in the social attitude, maybe similar to comparing Colombia with Sweden.

    In Latin America you have to look after yourself and protect your own (and your family’s) interests at all expense, or else you risk being screwed by someone. This applies to everything from personal property, business, government, etc.

    In Canada there’s an underlying feeling of respect and care for one another, of protecting the “common wealth”.

    Of course this is a generalization and oversimplification of very complex realities, but this somehow gets ingrained into our children’s behavior.

      The epitomy of Canadian cooperation is the Capillano Suspension Bridge in Vancouver, BC: Every day after 3 PM or so, the bridge switches to single lane heading into town. This means that there are 4 lanes of busy traffic merging into one. Every time I take part in that event I am amazed at the smoothness with which this occurs and the courtesy displayed by (otherwise fairly aggressive) drivers. In most other countries I have visited or lived in there would be at least some incidents and possibly warfare. Not in Vancouver

        Of course I meant *Lion’s Gate Bridge*, not Capillano Suspension. You would not get a Smart car on Capillano, let alone 4 lanes of traffic.

        One should not post on empty stomach.

        I meant what I said (re apology) on or off an empty stomach. Never heard of the Capillano Suspension and as for the Lion’s Gate- Reminds me of why people own dogs- They say boo- or ruff, ruff- and the criminals run away- like scarety cats. Boys will remain boys. Only a few grow up. I happen to be married to one who grew up here in America the hard way–without mother or father to protect him. He learned to fight for himself and I learned from him. So whether with or without food- better look before you leap off a bridge.

    Sweden is a relatively homogenous society while Colombia is not. People who are alike tend to work together better than those who are different. Think Japan or China.

    India is the perfect example. Not only do they have 650 ethnic tribes but within those tribes many have divided themselves further by castes. Consequently, there is very little cooperation relative to other countries.

    It would be interesting to compare the United States with Sweden.

      Dear AngelA;

      Sorry, but the translation already exists on several fronts. I guess Romny ought to read Goldstein’s dissertation (1991, Max Weber’s Contribution to `knowledge’ of the origins of chinese thought). The bottom line is- there needs to be a real bottom line of treating one another with respect beyond which we do not go. The thought of pre-history repeating itself is too much for one individual to bear. . and the need for environmental, health, … protection against the destructive threat that we humans seem to pose to our environment and to each other should be a real bi-partisan committment – that teaches the chinese a thing or two about America and the real need for a mutual orientation of our activities in the struggle for advantages and for human survival on our planet.
