We argue that a social norm and the coordination of behavior within social groups can be expressed by a correlated equilibrium. Given a social group structure (a partition of individuals into social groups), we propose four conditions that one may expect of a correlated equilibrium consistent...

What has caused the rising gap in health insurance coverage by education in the U.S. over the last thirty years? How does the employment-based health insurance market interact with the labor market? What are the effects of social insurance such as Medicaid? By developing and structurally...

For each of three types of ambiguity, we compute a robust Ramsey plan and an associated worst-case probability model. Ex post, ambiguity of type I implies endogenously distorted homogeneous beliefs, while ambiguities of types II and III imply distorted heterogeneous beliefs. Martingales...

This paper studies the interaction between technology, a publicly available input that flows in from abroad, and human capital, a private input that is accumulated domestically, as the twin engines of growth in a developing economy. The model displays two types of long run behavior, depending on...

We examine the housing market, residential mobility, and academic performance changes that occur soon after a school fails to achieve Adequate Yearly Progress (AYP) (for the second time) in the Charlotte, NC school district. Charlotte is a school district with substantial opportunities for...

This paper examines the demographic pattern of friendship links among youth and the impact of those patterns on own educational outcomes using the friendship network data in the Add Health. We develop and estimate a reduced form matching model to predict friendship link formation and identify...

In the past decades, behavioural economics has become an influential and important field of economics. Interest in behavioural economics derives from unease with standard economic models that are based on restrictive assumptions, which confine the nature of human motivation. Although Adam Smith,...

High rewards or the threat of severe punishment do not only provide incentives to exert high levels of effort but also create pressure. Such pressure can cause paradoxical performance effects, namely performance decrements despite strong incentives and high motivation. By analyzing the...
