In this paper, we develop a revealed preference methodology that allows us to explore whether time inconsistencies in household choice are the product of individual preference nonstationarities or the result of individual heterogeneity and renegotiation within the collective unit. An empirical...

This paper provides a revealed preference characterisation of quasi-hyperbolic discounting which is designed to be applied to readily-available expenditure surveys. We describe necessary and sufficient conditions for the leading forms of the model and also study the consequences of the...

This paper focuses on two main issues. First, we find that, on average, households' discount rates decline. This implies dynamically inconsistent preferences. Second, we calculate an indicator of the degree of dynamic inconsistency that may help us to understand how households overcome their...

This paper develops a revealed preference methodology for exploring whether time inconsistencies in household choice are the product of nonstationarities at the individual level or the result of individual heterogeneity and renegotiation within the collective unit. An empirical application to...

This paper focuses on two main issues. First, we find that, on average, households’ discount rates decline. This implies dynamically inconsistent preferences. Second, we calculate an indicator of the degree of dynamic inconsistency that may help us to understand how households overcome their...

Rising prevalence of obesity among adults and children is a major policy issue in many countries. Two widely discussed instruments to address obesity are a tax on unhealthy foods (fat tax) and a subsidy on healthy foods (thin subsidy). We compare these two policies to a sales tax on all food...

In order to explain the substantial recent increases in obesity rates in the United States, we consider the effect of falling food prices in the context of a model involving endogenous body weight norms and an explicit, empirically grounded description of human metabolism. Unlike previous...

This paper addresses the question whether taxes on unhealthy food are suitable for internalizing intergenerational externalities inflicted by parents when they decide on their children's diet. Within an OLG model with an imperfectly altruistic parent, the optimal steady state tax rate on...

The positive correlation between hourly wages and height, which results in higher labor supply of tall individuals, is well-documented in the literature. Accepting the utilitarian perspective and assuming that height does not affect utility implies that linking income taxes to height is welfare...
