The aim of this article is to estimate the type of selection that exists in the voluntary health insurance market in Colombia where the compulsory coverage is implemented through a managed care competition. We build a panel database that combines individuals’ information from the Ministry of Health...

In this paper, we consider a symmetric contest game in which agents compete to increase their share of a risky rent. We show that a symmetric equilibrium always exists, and that it is unique under constant or decreasing absolute risk aversion. We then exhibit interpretable conditions so that...

CTL (Cytotoxic T. Lymphocytes) destroy virally infected cells and tumor cells via the secretion of lytic molecules stored in intracellular granules. They are key components of the anti-cancer immune response and it is therefore crucial to study in depth, and possibly enhance, their biological...

This paper deals with a natural stochastic optimization procedure derived from the so-called Heavy-ball method differential equation, which was introduced by Polyak in the 1960s with his seminal contribution [Pol64]. The Heavy-ball method is a second-order dynamics that was investigated to minimize...

Recent advances in economic theory, largely motivated by experimental findings, have led to the adoption of models of human behavior where a decision-maker not only takes into consideration her own payoff but also others’ payoffs and any potential consequences of these payoffs. Investigations of...

Public enforcement of law relies on the use of public agents, such as judges, to follow the law. Are judges motivated only by strategic interests and ideology, as many models posit, rather than a duty to follow the law? We use the random assignment of U.S. Federal judges setting geographically-...

We present and test a model of mandatory disclosure. The effects of disclosure laws on what is being disclosed are typically unknown since data on disclosed activity rarely exist in the absence of disclosure laws. We exploit data from legal settlements disclosing $316 million in pharmaceutical...

The study of the normative and positive theory of choice under uncertainty has made major advances through thought experiments often referred to as paradoxes: the St. Petersburg paradox, the Allais paradox, the Ellsberg paradox, and the Rabin paradox. Machina proposes a new thought experiment which...

We investigate how people trade off between equity and efficiency, using variations of tripled dictator and trust games in a lab experiment. Equalizing payoffs reduces the return from the tripled investment in the dictator game. In contrast, in the trust game both equal and maximized payoffs can be...

In this paper we estimate the degree of substitutability for advertisers across different media outlets. The estimates are motivated by the need that competition agencies have to properly characterize the relevant market when dealing with mergers in the media industry. As technology changes the...
