How should countries in a fixed exchange rate system balance their current account? This question was at the center of the historical debate between Keynes and White in 1944 and is being debated increasingly these days for the Eurozone. Should consolidation by deficit countries be complemented by higher spending in surplus countries in order to avoid a downward bias in the level of consumption? We investigate the associated disequilibrium behavior experimentally, letting our experimental subjects act as heads of state who repeatedly seek to coordinate their policies. If only deficits are punished, as proposed by White, we observe that consumption is persistently reduced and adjustment is slower than in a treatment in which a surplus is also punished, as suggested by Keynes. We find support for the fact that underconsumption occurs for behavioral but not for rational reasons.

We examine strategic awareness in experimental games, that is, the question of whether subjects realize they are playing a game and thus have to form beliefs about others’ actions. We conduct a beauty contest game and elicit measures of cognitive ability and beliefs about others’ cognitive ability. We show that the effect of cognitive ability is highly non-linear. Subjects below a certain threshold choose numbers in the whole interval and their behavior does not correlate with beliefs about others’ ability. In contrast, subjects who exceed the threshold avoid choices above 50 and react very sensitively to beliefs about the cognitive ability of others.
