We study the welfare properties of a general equilibrium banking model with moral hazard that encompasses incentive mechanisms for bank risk-taking studied in a large partial equilibrium literature. We show that competitive equilibriums maximize welfare and yield an optimal level of banks' risk...

Attracting attention is a basic feature of economic life but no standard economic problem. A new theoretical model is developed which describes the general structure of competition for attention and characterizes equilibria. The exogenous fundamentals of an attention economy are the space of...

We integrate individual power in groups into general equilibrium models. The relationship between group formation, resource allocation, and the power of specific individuals or particular sociological groups is investigated. We introduce, via an illustrative example, three appealing concepts of...

In this work we deal with the theory of price determination in Steuart's writings; in particular with the concept of Double competition. The background is the evolution of the concept of market during the 18th century. Steuart proposed a theoretical construction in order to tackle the problem of...

We develop a tractable RBC model of the stock market with heterogenous firms. Shares value rests on the rent extracted from proprietary technology à la Dixit-Stiglitz. We prove the existence and uniqueness of the fundamental equilibrium. Closed form solutions are provided for the market...

We present a dynamical model of web site growth in order to explore the effects of competition among web sites and to determine how they affect the nature of markets. We show that under general conditions, as the competition between sites increases, the model exhibits a sudden transition from a...

We develop a tractable equilibrium model of competing firms in an industry to show how the distribution of firm qualities, moral hazard, and product market characteristics interact to affect firm size, managerial compensation, and market structure. Equilibrium effects cause different...

In A Mathematical Formulation of the Ricardian System, Pasinetti (1960) lays out the foundations of what has been dubbed the canonical classical model. He proves the model to be logically consistent and determinate in all its macro-economic features, and derives the solutions for all key...
