The notion of solution plays a crucial role in the conceptual system of Léon Walras, the founder of General Equilibrium Theory (GET). In this paper, after introducing the two solution concepts employed by Walras in the development of his version of GET, respectively called the "theoretical" and...

This paper extends the dynamic Mirrlees model to general equilibrium and derives the optimal social insurance policies against persistent idiosyncratic risk over the life cycle. Agents are heterogeneous in their work ability, which is private information and evolves stochastically over time, and...

We study an overlapping generations version of the principal-agent problem, where incentive contracts are determined in general equilibrium. All individuals are workers when young, but have a choice between becoming entrepreneurs or remaining workers when old. Imperfections in the credit market...

In a fundamental contribution, Prescott and Townsend (1984) [PT] have shown that the existence and efficiency properties of Walrasian equilibria extend to economies with moral hazard, when agents' trades are observable (exclusive contracts can be implemented). More recently, Bennardo and...

A competitive market mechanism is a prominent example of a nonbinary social choice rule, typically defined for a special class of economic environments in which each social state is an economic allocation of private goods, and individuals’ preferences concern only their own personal...

We consider optional TOU (time-of-use) pricing for residential consumers as an alternative to a single TOU or flat rate structure offered by a publicly regulated electricity supplier. A general equilibrium model is developed and used to explore and quantify the effects of optional pricing on...

A system of thought allowed for the free market price of land to cyclically go down to zero. This is the economics of Moses. The economics of Jesus is a restatement of the economics of Moses. The first was applied during Biblical times and the latter, united with Aristotle’s thought and...

During the second half of the twentieth century economic theory moved increasingly away from price theory, which was gradually displaced by more modern trends such as game theory, decision theory, behavioral-empirical-experimental economics, heterodox economics, etc. This was due to serious...

This paper develops a discussion and provides the basis for a dispute of the principal assumption on which the classical-neoclassical theory of perfect competition is based: is it indeed true that the individual product demand of each producer is perfectly elastic (horizontal) and the price is...
