We study how competition impacts innovation (and welfare) when firms compete both in the product market and in innovation development. This relationship is complex and may lead to scenarios in which a lessening of competition increases R&D and consumer welfare in the long run, contradicting...

The present document resumes the work of tree papers regarding college selection system. These investigations evaluate the use of the “high school ranking” of students as a college selection variable. The authors evaluate the performance of students in the University of Chile, Catholic...

I examine the impact of patent policy — characterized by patent length and strength — on R&D investment dynamics and the number of competitors in the context of sequential innovation. Overly protective policies introduce two distortions: they delay leaders' and followers' investments toward...

We study market entry decisions when firms have private information about their profitability. We generalize current models by allowing general forms of market competition and heterogeneous firms that self-select when entering the market. Post-entry profits depend on market structure, and on the...

Motivated by a longitudinal oral health study, the Signal--Tandmobiel® study, we propose a multivariate binary inhomogeneous Markov model in which unobserved correlated response variables are subject to an unconstrained misclassification process and have a monotone behavior. The multivariate...

The effects of Bénard flows on diffusion-limited aggregation (DLA) is investigated by a growth pattern formation (GPF) computational model. The GPF introduced consists of a DLA process driven by a thermal convection field in a plane viscous incompresible flow. The flow regime is governed by the...

In this paper we investigate the dual role of supply restrictions and drug treatment in combating the concurrent rise of opioid abuse and suicide in the United States over the last two decades. We find that supply-side interventions decrease suicides in places with strong addiction-help...
