We analyze the effects of CEOs' layoff risk on their risk choice while overseeing a firm. A CEO, whose managerial ability is unknown, is fired if her expected ability is below average. Her risk choice changes the informativeness of output and market's belief about her ability. She can decrease...

This paper presents a theoretical framework to describe the behaviour of the credit rating agencies(CRAs) during the crisis, surveying some reputational game models. CRAs have been blamed of inflating ratings of the new credit risk transfer products (CRTs) and of acting in favour of issuers...

We interpret the social identity literature and examine its economic implications. We model a population of agents from two exogenous and well defined social groups. Agents are randomly matched to play a reduced form bargaining game. We show that this struggle for resources drives a conflict...

In a model of repeated games, we determine the conditions under which cooperation is an equilibrium outcome among the G-20 countries. We consider first, that members are uncertain about the lifespan of the G-20. Second, the nature of member countries and their interrelations can change because...

The theory of institutional traps, i.e. ineffective but stable institutions or behavior norms, is develope din connection with economic reforms. Mechanisms are described that cause a system to get into a trap and ways of going out of it are analyzed. Concepts of transformation costs and...

People are interacting more with strangers thanks to recent technological advancement in online platforms. Online interactions can be characterized by infinitely-repeated games. Recent studies have shown that institutions that make people’s decisions open to others may enhance cooperation in...

Employment contracts give a principal the authority to decide flexibly which task his agent should execute. However, there is a tradeoff, first pointed out by Simon (1951), between flexibility and employer moral hazard. An employment contract allows the principal to adjust the task quickly to...

We propose a sectoral-shift theory of aggregate factor productivity for a class of economies with AK technologies, limited loan enforcement, a constant production possibilities frontier, and finitely many sectors producing the same good. Both the growth rate and total factor productivity in...

This paper incorporates learning and reputation building into a simple dynamic stochastic model of international trade with asymmetric information. We use the model to study a bilateral trade flow influenced significantly by learning and reputation, namely U.S. imports of Japanese cars over the...

Reputation systems aim to induce honest behavior in online trade by providing information about past conduct of users. Online reputation, however, is not directly connected to a person, but only to the virtual identity of that person. Users can therefore shed a negative reputation by creating a...
