The authors develop an ordinal approach to comparing the equilibria of economic models. Its main advantages over the traditional approach based on signing derivatives are that it utilizes only a subset of the assumptions, resulting in a simpler theory that facilitates focusing attention on the...

Manufacturing is undergoing a revolution. The mass production model is being replaced by a vision of a flexible multiproduct firm that emphasizes quality and speedy response to market conditions while utilizing technologically advanced equipment and new forms of organization. The authors'...

This paper presents a general-equilibrium model in which all prices and quantities transacted are the direct choices of econom ic agents: there is no Walrasian auctioneer. Multiple subgame perfect equilibria exist with prices and wages at their Walrasian levels. Among the equilibrium allocations...

The LeChatelier principle, in the form introduced into economics by Paul A. Samuelson, asserts that, at a point of long-run equilibrium, the derivative of long-run compensated demand with respect to own price is larger in magnitude than the derivative of short-run compensated demand. The authors...
