We develop a simple model where two technologies are available to produce the same good, and we study under what conditions both will be used. We use the model to analyze the consequences of the simultaneous use of two different technologies for the economic variables and economic growth....

Asymmetric information is an important source of inefficiency when an asset (such as a firm) is transacted. The two main sources of this asymmetry are the unobserved idiosyncratic characteristics of the asset (such as future profitability) and unobserved idiosyncratic choices (like secret price...

This paper investigates how cooperation can be sustained in large societies even in the presence of agents who never cooperate. In order to do this, we consider a large but finite society where in each period agents are randomly matched in pairs. Nature decides, within each match, which agent...

This paper analyses the relation between parents’ earnings and their children's education. In a context of perfect altruism, the model describes parents’ decisions on how much to consume and how much to invest in their children's education. The model predicts that returns on education in...

Asymmetric information is an important source of inefficiency when assets (like firms) are transacted. The two main sources of this asymmetry are unobserved idiosyncratic characteristics of the asset (for example, quality) and unobserved idiosyncratic choices (actions done by the current...

Consider the following situation involving two agents who belong to a large society. One of the agents needs help to avoid a big loss. The other agent may either incur a low cost to help him or do nothing. If agents do not recognize each other, providing incentives for socially optimal behavior...
