The U.S. economy had experienced the "jobless recovering" after the 1990-1991 and 2001 recessions, which has been constantly puzzling the economists, market analysts, and policymakers. This paper uses a simple hiring game in an efficiency wage model framework to resolve that puzzle. Our...

Using an efficiency-wage model, we examine the relationship between indeterminacy and unemployment insurance. It is shown that the less unemployment insurance is, the more likely equilibrium is to be indeterminate. Equilibrium can be indeterminate even without externalities or increasing...

This paper combines matching frictions with e¢ ciency wages to deter shirking in a model that is estimated for the USA and the UK to derive the underlying structural parameters. Methods robust to weak instruments are used to show that, for both countries, both matching frictions and efficiency...

For an exchange economy, under assumptions which did not bring about the existence of equilibrium with dividends as yet, we prove the non-emptiness of the fuzzy rejective core. Then, via Konovalov (1998, 2005)'s equivalence result, we solve the equilibrium with dividends existence problem....

In contrast to Mandler's (1999a; Theorem 6) impossibility result about the Sraffian indeterminacy of the steady-state equilibrium, we first show that any regular Sraffian steady-state equilibrium is indeterminate in terms of Sraffa (1960) under the simple overlapping generation economy. Moreover, we...

We address some open issues regarding the characterization of double auctions. Our model is a two-sided commodity market with either finitely or infinitely many traders. We first unify existing formulations for both finite and infinite markets and generalize the characterization of market...

We provide necessary conditions for Pareto optimum in economies where tastes or technologies may be nonconvex, nonsmooth, and affected by externalities. Firms can pursue own objectives, much like the consumers. Infinite-dimensional commodity spaces are accommodated. Public goods and material...

This paper analyzes the problem of selecting a set of items whose prices are to be updated in the next iteration in so called simple ascending auctions with unit-demand bidders. A family of sets called "sets in excess demand" is introduced, and the main results demonstrate that a simple...

We present a comprehensive theory of large non-anonymous games in which agents have a name and a determinate social-type and/or biological trait to resolve the dissonance of a (matching-pennies type) game with an exact pure-strategy Nash equilibrium with finite agents, but without one when...

This paper analyzes a general-equilibrium model in which each person can choose to be either a producer or a predator. This model shows how predation breaks the link between the interpersonal distribution of productive resources and the interpersonal distribution of consumption. SpeciÞcally, we...
