The study of evolutionary dynamics was so far mainly restricted to finite strategy spaces. In this paper we show that this unsatisfying restriction is unnecessary. We specify a simple condition under which the continuous time replicator dynamics are well defined for the case of infinte strategy...

This paper develops a model of political consensus in order to explain the missing link between inequality and political redistribution. Political consensu s is an implicit agreement not to vote for extreme policy proposals. We show tha t such an agreement may play an efficiency-enhancing role....

A notion of ''behavioral heterogeneity'' of a finite population of households is modelled. It is shown that the higher the degree of behavioral heterogeneity the less sensitive depends the aggregate consumption expenditure ratio upon prices.As a consequence, behavioral heterogeneity implies a...

In a general setting of private information, the possibility (impossibility) theorem is said to be valid, if a balanced and ex post efficient mechanism exists (does not exist) which agents voluntarily participate at. Possibility and impossibility results are called robust if they hold for all...

In this note we consider the problem whether contingent commodity allocations can be used when the states are not directly contractible. In such a setting a contingent commodity allocation takes the form of a social choice function, and the question is whether this function is implementable (in...

Quasimonotone individual demand correspondences are characterized as those which can be rationalized (in a weak sense) by a complete, upper continuous, monotone, and convex preference relation. Moreover, it is shown that an arbitrary set of demand observations can be rationalized by a reflexive,...

The financial structure of firms is diverse. Firms issue many different types of financial claims. This article focuses on the seniority structure of debt contracts. It is outlined under what conditions firms can improve the outcome of their financial decisions by choosing seniority structure....

J.M. Grandmont claims in his paper "Transformations of the Commodity Space, Behavioral Heterogeneity, and the Aggregation Problem" (1992) to model "behavioral heterogeneity". By a specific parametrization he defines a subset of all demand functions and assumes that the distribution of the...

We study changes of the distribution of income, age, occupation, household size via their marginal and conditional densities. The data consists of cross sectional samples from the population of Brithish households drawn over the years of 1968 - 1995. Estimation is carried out nonparametrically...

This paper analyses management style as a governance mechanism in agency relationships when the lack of verifiable information restricts the contracting possibilities. Specifically, it investigates whether decision making should be supplemented by prior verification, and how these tasks should...
