Sleep is a source of energy. This energy is available in limited quantity and individuals must decide when it should be renewed and when it should be consumed. The economics of sleeping and the economics of resource extraction are one and the same. More specifically, utility maximization with...

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...

This paper is concerned with the axiomatic foundation of the revealed preference theory. Many well-known results in the literature rest upon the ability to choose over budget sets that contain only 2 or 3 elements. This paper shows that for any given choice function, many of the famous...

Former theoretical and empirical studies find that precautionary savings are reduced inthe presence of social security systems. The saving motive, however, does not change:individuals respond to increasing income risk by increasing their savings. Although thisstill holds for common tax and...

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...

We develop the theory of demand for commodities and assets facing incompletely insurable uncertainty. First, a Slutsky matrix decomposes into substitution and income effects the derivative of demand with respect to prices and yield structure. Next, we identify the Slutsky matrix’s properties....

This paper analyzes dynamic equilibrium risk sharing contracts between profit-maximizing intermediaries and a large pool of ex-ante identical agents that face idiosyncratic income uncertainty that makes them heterogeneous ex-post. In any given period, after having observed her income, the agent...

The literature on household behavior contains hardly any empirical research on the withinhousehold distributional effect of tax-benefit policies. We simulate this effect in the framework of a collective model of labor supply when shifting from a joint to an individual taxation system in France....

Several theoretical contributions, starting with McElroy and Horney (1981) and Manser and Brown (1980), have suggested to model household behavior as a Nash-bargaining game. Since then, very few attempts have been made to operationalize cooperative models of household labor supply for policy...

The paper introduces the concept of adjustment utility, that is, referencedependent utility from expectations. It offers an explanation for observed preferences that cannot be explained with existing models, and yields new predictions for individual decision making. The model gives a simple...
