The present note shows that the concept of a distribution economy (Hildenbrand (1974)) is closely related to a framework of an exchange economy in which the agents’ individual characteristics (i.e. preferences and endowments) are random (Hildenbrand (1971), Bhattacharya and Majumdar (1973),...

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...

This article studies the long-run direction of technological change in an endogenous growth model. Development is modeled as a sequence of temporary equilibria in an overlapping generations framework. We introduce a concept of `long-run efficient development' which excludes persistent...

We introduce a framework of development in which the direction of change is determined endogenously. Which new products, which new qualities and which new techniques are introduced in the course of development is determined by the profitability of different potential innovations. We define a...

In the context of standard two-period pure-exchange economies with sequential trade, this paper proposes a decentralized coordination mechanism for equilibriumexpectations, facilitated by local interactions between agents. Interactions are modelled stochastically by specifying a family of...

We analyze the life cycle consumption choice model for multiple goods, focusing on the distinction between durables and perishables. As an approximation of the fact that rather high transaction costs and market imperfections prevail in markets for used durables, we assume that investment in...

Structural Properties of the demand of a large population introduced by the aggregation process are studied. The idea is to consider assumptions on the distribution of household characteristics rather than focusing on the modelling of individual behavior. By opposite to the existing literature...

This paper deals with the role of bubbles, having the same meaning as Ponzi games, for implementing efficient growth paths in a closed economy overlapping generations model. It is shown that the well-known arbitrage condition for bubbles, namely that they must yield the same return in...
