We analytically show that a common across rich/poor individuals Stone-Geary utility function with subsistence consumption in the context of a simple two-asset portfolio-choice model is capable of qualitatively and quantitatively explaining: (i) the higher saving rates of the rich, (ii) the...

We consider a model of firm pricing and consumer choice, where consumers are loss averse and uncertain about their future demand. Possibly, consumers in our model prefer a flat rate to a measured tariff, even though this choice does not minimize their expected billing amount - a behavior in line...

This paper finds declining consumption expenditure between paydays, for a typical household in the working population of the UK. The magnitude is inconsistent with exponential time preference, but compatible with quasi-hyperbolic discounting. However, the hyperbolic model predicts that credit...

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...

This paper deals with different concepts of income elasticities of demand for a heterogenous population and the relationship between individual and aggregate elasticities is analyzed. In general, the aggregate elasticity is not equal to the mean of individual elasticities. The difference depends...

This paper shows how sustainable consumption patterns can spread within a population via processes of social learning even though a strong individual learning bias may favor environmentally harmful products. We present a model depicting how the biased transmission of different behaviors via...

A characteristic feature of economic development is the ever changing structure of consumption patterns. Reducing the explanation of this phenomenon to changing prices, finally caused by changes in the availability of goods (or characteristics), would neglect a major force driving this change,...

We provide a nonparametric 'revealed preference' characterization of rational household behavior in terms of the collective consumption model, while accounting for general (possibly non-convex) individual preferences. We establish a Collective Axiom of Revealed Preference (CARP), which provides...

This article considers non-unitary models of household behavior. These models suppose explicitly that households consist of a number of different members with preferences that are different from each other. They can be split up into two principal categories: cooperative (or collective) models,...

The so called flat-rate bias is a well documented phenomenon caused by consumers' desire to be insured against fluctuations in their billing amounts. This paper shows that expectation-based loss aversion provides a formal explanation for this bias. We solve for the optimal two-part tariff when...
