The aim of this paper is to propose an analytical framework, wherein the individuals' choice problem is addressed in terms of alternative time‐consuming activities rather than in terms of alternative bundles of goods and services. In particular, the paper reverses Becker's (1965) proposal to...

This paper investigates empirically why Japan’s household savings rate fell in the 1990s. We constructed an economic model consisting of two types of household: unconstrained life-cycle households and liquidity-constrained households. Unconstrained households generally save, but...

A notion of "behavioral heterogeneity" of a finite population of households is modelled. It is shown that the higher the degree of behavioral heterogeneity the less sensitive depends the aggregate consumption expenditure ratio upon prices. As a consequence, behavioral heterogeneity implies a...

This paper is divided into two parts which deal with closely connected issues, The first section of the paper explores the structure of consumer demand systems necessary and sufficient for exact aggregation. The second section addresses a related empirical question: what, if anything, do the...

Considering a consumer with standard preferences, I trace out the consequences for risk aversion and prudence of quantity constraints on markets. I first show how the effect can be decomposed into a price risk effect and an endogenously changing risk aversion/prudence effect. Next, I calibrate...

We present a household consumption model that accounts for caring household members, while allowing for noncooperative behavior in decisions on public goods. The intrahousehold consumption outcome critically depends on the degree of caring between the household members. By varying the degree of...
