It has been argued that hyperbolic discounting of future gains and losses leads to time-inconsistent behavior and thereby, in the context of health economics, not enough investment in health and too much indulgence of unhealthy consumption. Here, we challenge this view. We set up a life-cycle...

We use administrative data for Norway to estimate an incomplete-market life-cycle model of retired singles and couples with a bequest motive, health-dependent utility, and uncertain longevity and health. We allow the parameters of the bequest utility to differ between households with and without...

This paper uses detailed diary information from the British Family Expenditure Survey (FES) to investigate the expenditure patterns of school-age children. We estimate a Quadratic Almost Ideal Demand System, and find that, whilst most commodities are normal goods, sweets and toys are luxury...

We provide a revealed preference analysis of the transferable utility hypothesis, which is widely used in economic models. First, we establish revealed preference conditions that must be satisfied for observed group behavior to be consistent with Pareto efficiency under transferable utility....

Duty-orientation implies a warm glow of giving as well as a cold shiver of not giving enough. If duty-oriented consumers learn their moral responsibility by observing others' behavior, social interaction in contribution behavior arises. However, since moral responsibility is a burden,...

In this paper we remark on the existence of a link between monetary income constraint and price elasticity of demand. This finding allows us to rewrite, and extend, the standard Engel Aggregation Condition, in terms of price elasticity, and not only with regard to income elasticity of demand

A theory in which the timing of consumer expectation adjustments is endogenously state-dependent and stochastic is proposed. These expectation adjustments generate highly heterogenous consumption responses to income windfalls: many households do not respond, those who do over-react, the marginal...
