Using CEX data from years before and after the enforcement policies were implemented, I isolate child- and mother-specific expenditure categories for unmarried mothers with and without child support and regress the ratio of mother to child expenditures over period dummies and mother and child...

We study a model of efficient risk sharing between two agents, A and B, who enjoy a non-durable common good. Only agent B can provide the common good whereas agent A can merely contribute indirectly by making transfers to the provider, agent B. We consider self-enforcing equilibria in the...

Capital markets function as aggregators of private information and in an environment with imperfectly informed firms, guide investment and production decisions. We study the implications of poorly functioning capital markets for the misallocation of factors of production across heterogeneous...

The paper considers formally the mapping from distortions to the allocations of resources across firms to aggregate productivity. TFP gaps are characterized as the integral of a strictly concave function with respect to an employment-weighted measure of distortions. Size related distortions are...

We propose a theory linking imperfect information to resource misallocation and hence to aggregate productivity and output. In our setup, firms learn from both private sources and imperfectly informative stock market prices. We devise a novel calibration strategy that uses a combination of...

This paper examines the consequences of child support enforcement on custodial mothers' consumption decisions. We model the interaction in separated couples as a repeated game between the noncustodial father and the custodial mother who share a common good: the child. The mother exclusively...

This paper studies the provision of a public good between two agents under lack of commitment and applies it to the problem of children's consumption in separated couples, where children are considered to be public goods. The custodial mother controls the child's consumption, whereas the father...

How is cooperation without immediate reciprocity sustained in a long term relationship? We study the case of two players in continuous time who have privately observable opportunities to provide favors, and where the arrival of these opportunities is a Poisson process. Favors provided by a...

It may be advantageous to provide a variety of kinds of patent protection to heterogenous innovations. Innovations which benefit society largely through their use as building blocks to future inventions may require a different scope of protection in order to be encouraged. We model the problem...
