We propose an objective for the firm in a model of production economies extending over time under uncertainty and with incomplete markets. We derive the objective of the firm from the assumption of initial-shareholders efficiency. Each shareholder is assumed to communicate to the firm her...

The theory of games against nature relies on complete preferences among all conceivable acts (case 1). Aumann and Drèze (Am Econ J Microecon 1(1):116,(2009) consider situations where preferences are defined only for a given set of acts (case 2).We extend these results to situations where (i)...

The label quot;Keynes-Negishi equilibriaquot; is attached here to equilibria in a monetary economy with imperfectly competitive product and labor markets where business firms and labor unions hold demand perceptions with kinks - as posited in Negishi's 1979 book Microeconomic Foundations of...

In recent decades, the concept of subjective probability has been increasingly applied to an adversary's choices in strategic games. A careful examination reveals that the standard construction of subjective probabilities does not apply in this context. We show how the difficulty may be overcome...

European economic integration leads to increasing factor mobility, thereby threatening the stability of social transfer programs. This paper investigates the possibility of achieving, by means of voluntary matching grants, both the optimal allocation of factors and the optimal level of...

Consider a population of citizens uniformly spread over the entire plane, that faces a problem of locating public facilities to be used by its members. The cost of every facility is financed by its users, who also face an idiosyncratic private access cost to the facility. We assume that the...

A number of specific conclusions and recommendations have emerged from my discussion of readily available data. But such data remain scanty. More research is needed on almost every point touched here. I invite the EEA to promote such research, in the same way that it did earlier for rankings of...

The theory of games against nature relies on complete preferences among all conceivable acts, i.e. among all potential assignments of consequences to states of nature (case 1). Yet most decision problems call for choosing an element from a limited set of acts. And in games of strategy, the set...

The paper studies equilibria for economies with imperfect competition and non-convex technologies. Following Negishi, firms maximise profits under downward-sloping perceived demand functions. Negishi's assumptions, in particular the assumption of a single monopolistic competitor in each market,...
