Currently no refinement exists that successfully selects equilibria across a wider range of Cheap Talk games. We propose a generalization of refinements based on credible deviations, such as neologism proofness and announcement proofness. According to our Average Credible Deviation Criterion...

Using simple game-theoretical models, this paper studies the role of pre-determined rules for HRM policies. We consider a model in which HRM decisions affect employees' self-images and thereby their motivation. We show that in the absence of written rules, managers are too reluctant (1) to...

When hiring an adviser (he), a policy maker (she) often faces the problem that she has incomplete information about his preferences. Some advisers are good, in the sense that their preferences are closely aligned to the policy maker's preferences, and some advisers are bad. Recently, some...

We develop a simple model that describes individuals’ self-assessments of

A physician performs two tasks: making diagnoses and determining treatments. To reduce medical error, residents are supposed to consult their supervisors when they face uncommon circumstances. However, recent research shows that residents are reluctant to do so. This paper presents a model that...

This paper formalizes the idea that more hedging instruments may destabilize markets when traders are heterogeneous and adapt their behavior according to experience based reinforcement learning. We investigate three different economic settings, a simple mean-variance asset pricing model, a...

We develop an economic theory of “flexibility”, which we interpret as the discretion or ability to make a decision that others disagree with. We show that flexibility is essentially an option for the decisionmaker, and can be valued as such. The value of the flexibility option is decreasing...

In this paper we introduce flexibility as an economic concept and apply it to the firm’s security issuance decision and capital structure choice. Flexibility is the ability to make decisions that one thinks are best even when others disagree. The firm’s management values flexibility because...

In this paper we analyze an entrepreneur /manager's choice between private and public ownership in a setting in which management needs some "elbow room" or autonomy to optimally manage the firm. In public capital markets, the corporate governance regime in place exposes the firm to exogenous...

We develop a theoretical framework for studying the effects of interaction on the quaJity of decision-making by monetary policy committees. We show that interaction, i.e. increasing one's expertise through an exchange of views, is most likely not to result in interdependent voting...
