In a production economy, multiple public goods are produced by firms in competitive markets, and provided by the government together with contributions from consumers. There are widespread externalities: all consumers' consumption and contributions and all firms' production enter into utility...

Traditional ways to prove the existence of general equilibrium have to entail a common condition that the excess demand function must be continuous. This paper presents a new approach to change it. The technique used in this paper is that we tackle general equilibrium problem, which in fact is a...

In this paper the existence of unemployment is partly explained as being the result of coordination failures. This is achieved by considering a standard general equilibrium model and splitting the set of commodities in two groups. The first group contains commodities like gold. The prices of...

We derive sufficient conditions for the existence of multiple equilibria in two-good, two-agent pure exchange economies with heterogeneous but symmetric preferences with identical Bernoulli utilities. When preferences are non-homothetic (e.g., quadratic, quasi-linear, or HARA), multiple...

In this paper, I study the existence and uniqueness of recursive equilibria in economies with aggregate and idiosyncratic risk. Rather than relying on compactness to establish existence, I exploit the monotonicity property of the equilibrium model and rely on arguments from convex analysis. This...

We discuss a model, in which two agents may distribute finitely many objects among themselves. The conflict is resolved by means of a market procedure. Depending on the specifications, this procedure serves to implement bargaining solutions such as the discrete Raiffa solution, the...

In a standard general equilibrium model it is assumed that there are no price restictionsand that prices adjust infinitely fast to their equilibrium values. In this paper the set ofadmissible prices is allowed to be an arbitrary convex set. For such an arbitrary set it cannotbe guaranteed that...

Social demand functions result from the budget constrained maximization of "social preferences" or "other regarding preferences." These preferences are non-selfish in the sense that they also depend on other consumers' wealth. This paper addresses the robustness to wealth externalities of the...

In an infinite-time decentralized sequence economy, agents use fiat money to bridge markets as if they make trades in a centralized economy, to avoid huge transaction cost that all agents' going together must incur. The model in this paper formulates the process how agents decide the fiat...
