This paper shows that the presence of conditional staging in R&D (Research & Development) has a critical impact on portfolio risk, and changes diversification arguments when a portfolio is constructed. When R&D projects exhibit option-like characteristics, correlation between projects plays a...

We model the emergence of organization forms in a game between prospective entrepreneurs. Complementary roles arise endogenously in a way that admits a stable assignment of workers to firms. This contrasts with existing work on job matching, where stability typically requires workers to be...

We show that a sufficient condition for the identification of all parameters of the censored regression model with a stochastic and unobserved threshold is that the errors are jointly normally distributed. Exclusion restrictions are not needed. <BR><BR>

This paper estimates the health returns to education, using data on identical twins. I adopt a twin-differences strategy in order to obtain estimates that are not biased by unobserved family background and genetic traits that may affect both education and health. I further investigate to what...

We examine the role of political factors in Mexico’s antidumping regime, considering both the characteristics of target countries subject to antidumping duties and industry-specific factors for sectors receiving protection. Our results are broadly consistent with the recent theoretical...

This paper formalizes the idea that more hedging instruments may destabilize markets when traders are heterogeneous and adapt their behavior according to experience based reinforcement learning. We investigate three different economic settings, a simple mean-variance asset pricing model, a...

We derive and discuss a general, but simple geographical economics model with congestion, allowing us to explain the economic viability of small and large locations. The model generalizes some previous work and lends itself to analyzing the impact of public policy in terms of infrastructure...

A large literature has emerged focusing on the post-entry performance of firms and, in particular, on the links between firm growth, survival, size and age. While these studies have resulted in findings that are sufficiently consistent as to constitute Stylized Facts, virtually all of these...

Conventional economic wisdom suggests that congestion pricing would be an appropriate response to cope with the growing congestion levels currently experienced at many airports. Several characteristics of aviation markets, however, may make naive congestion prices equal to the value of marginal...

We present a strategic game of pricing and targeted-advertising. Firms can simultaneously target price advertisements to different groups of customers, or to the entire market. Pure strategy equilibria do not exist and thus market segmentation cannot occur surely. Equilibria exhibit random...
