Mostly worked in the economics of human re
sources — human capital, labour supply and economics of the family. Papers reflect a dialogue between empirical work and theory — mostly extensions of microeconomic analysis to nonmarket activities. The theoretical model of human capital accumulation which generates the concave life-cycle of earnings was preceded by empirical work on this topic.
Interest in population generated by Kuznet’s work led to a series of empirical and micro-theoretical studies of fertility. This work on the family led to questions on the role of families in the institutional set-up of the economy and the importance of identity of transactions in a world of imperfect information. Interest in another border area, political economy, is reflected in an early paper which identified a political business cycle in Israel, analysis of the tax reform and recent work on the response of the public sector to demographic pressures.
