This paper compares predictions obtained for the analysis of tax reforms with collective and unitary models of household labour supply and consumption behaviour. We simulate real world microdata by means of a collective approach, using a compound procedure of estimation and calibration based on...

This paper assesses the effects that an introduction of the French family splitting mechanism would have on German families' labour supply and intra-household consumption behaviour. We use simulated real world microdata created by means of a "deterministic" collective labour supply model. The...

Several recent papers have shown the relevance of collective models for the empirical investigation of household labor supply and consumption. Yet the estimation of collective models in the presence of non-linear budget sets and participation decisions remains a daunting task. This paper...

Dieser Aufsatz beschreibt neuere Entwicklungen in der Aggregationstheorie sowie ausgewählte empirische Arbeiten. Diese stellen exemplarisch dar, wie die Mikroökonometrie eingesetzt werden kann, um Aggregationsprobleme zu untersuchen und approximative Lösungen zu finden. Der Schwerpunkt liegt...

We conducted an experiment on the nature of income sharing within 95 established couples in Germany. In a first step, the partners revealed their individual preferences by making consumption choices independently. In a second step, decisions were taken jointly over five different rounds with...

This paper addresses the behavioral puzzle of women's preference for competition when competitors are also women. Using a framed field experiment with 883 non-standard subjects, we show that none of the determinants of competitive behavior in general, including ability, self-confidence and risk...
