This paper has a dual purpose. First, I present a new modeling of partial naivete, and apply this to the analysis of procrastination. The decision maker is assumed to have stationary behavior and to be partially naive in the sense of perceiving that his current preferences may persist in the...

We analyze efficient risk-sharing arrangements when coalitions may deviate. Coalitions form to insure against idiosyncratic income risk. Self-enforcing contracts for both the original coalition and any deviating coalition rely on a belief in future cooperation which we term \social capital". We...

Simple life cycle and permanent income hypotheses imply that changes in consumption should be unforecastable. Rational forward-looking agents ought to smooth consumption over the life cycle and exhaust the asset stock accumulated during the working career in retirement. Empirical observations...

Vegetables play an important role in human nutrition, as they have a high content of nutrients. In the last five years, there has been a tendency to increase the consumption of vegetables among Romanians, this being attributed to the increase of the living standard, but also to the reorientation...

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...

It has been argued that increased life expectancy raises the rate of return on education, causing a rise in the investment in education followed by an increase in lifetime labor supply. Empirical evidence of these relations is rather weak. Building on a lifecycle model with uncertain longevity,...

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...

Consumption theory has always been a neglected field in Post Keynesian economics, whereas it is at the center of New Keynesian economics. This paper investigates similarities and differences between the two approaches. I will show that the newer mainstream models indeed give results that are...

We analyse how money as a store of value affects the decisions of a representative household under diversifiable and non-diversifiable risks. given that the central bank successfully stabilizes the rate of inflation at a low level. Assuming exponential utility allows us to derive an explicit...
