Equality-efficiency trade-off within French and German couples : a comparative experimental study ; conference paper

We present the results of an experiment that measures social preferences within couples in a context where intra-household pay-off inequality can be reduced at the cost of diminishing household income. We measure social norms regarding this efficiency-equality trade-off and implement a cross-country comparison between France and Germany. In particular, we show that German households are more inequality averse and are thus less efficient than French households. A decomposition of this difference reveals that approximately 40% is driven by diverging sample compositions in the two countries, while 60% of the initial French/German difference remains unexplained. Beliefs differ significantly from observed behavior in both countries. Efficient choices are overestimated in the German sample and underestimated in the French.
