This paper studies the welfare effects of R&D subsidies. We develop a model of continuous optimal treatment with outcome heterogeneity where the treatment outcome depends on applicant investment. The model takes into account heterogeneous application costs and identifies the treatment effect on...

We study the effects of investor protection on the availability of external finance, entrepreneurship, and creation of new firms in an equilibrium search model of private capital markets. In addition to search frictions, we examine contract frictions, specifically interim and ex post moral...

In the market for payment media, some consumers use only one medium when paying for their point-of-sale transactions, while others use many. This pattern reflects the diffusion of new payment media, because a payment method innovation is typically first used simultaneously with the established...
