It is argued that learnability/E-stability is a necessary condition for a RE solution to be plausible. A class of linear models considered by Evans, G.W. and Honkapohja, S. [2001. Learning and Expectations in Macroeconomics, Princeton University Press.] is shown to include all models of the form...

The abundance of flawed software has been identified as the main cause of the poor security of computer networks since major viruses and worms have been exploiting the vulnerabilities of such software. As an incentive mechanism for software security quality improvement, software liability has...

Previous research has shown that most consumer packaged goods markets are in long-run competitive equilibrium. In most categories, a given brand’s market share is stationary, showing remarkable stability over long time horizons (10 years). This empirical generalization has been attributed to...

The goal of this paper is to analyze consumer demand in markets with large price uncertainty. We develop a demand model for goods that are subject to habit formation. We show that consumption plans of forward looking individuals depend not only on preferences and current period prices, but also...

It is well known that scheduling jobs according to the Shortest-Remaining-Processing-Time (SRPT) policy is optimal for minimizing mean response time in a single-server system with online arrivals. Unfortunately, SRPT scheduling requires users to reveal their job size (service requirement), which...

This paper proposes a low cost alternative to the large bailout packages that the International Monetary Fund (IMF) has organized to address financial crises. The IMF would act as a lender of last resort. Faced with an unsustainable debt burden, a government would declare default. It would...

This paper formulates and estimates a dynamic model of labor supply, occupational sorting, human capital accumulation and discrimination to explain the narrowing gender earnings gap from 1968 to 1993. The paper proves the model is identified and develops a three-step estimation technique....

The paper reconsiders the role of money and banking in monetary policy analysis by including a banking sector and money in an optimizing model otherwise of a standard type. The model is implemented quantitatively, with a calibration based on US data. It is reasonably successful in providing an...

In this paper, we examine optimal job choices when jobs differ in the rate at which they reveal information about workers’ skills. We show that informational differences across jobs give rise to experimentation in that workers may be willing to sacrifice current period output in order to take...

We develop a pure moral hazard model, and a closely related hybrid one, where there are both hidden actions and hidden information, to derive the restrictions from optimal contract theory that characterize set identification. In pure moral hazard models, the expected utility of managers is...
