The main purpose of this paper is to estimate the probability of casting a decisive vote for a class or random electorate models encompassing the celebrated IC and IAC models. The emphasis is on the impact of correlation across votes on the order of magnitude of this event. Our proof techniques...

In this paper, we clarify the relationship between influence/power measurement and utility measurement, the most popular two social objective criteria used when evaluating voting mechanisms. For one particular probabilistic model describing the preferences of the electorate, the so-called...

We evaluate a simple allocation mechanism of students to majors at college entry that was commonly used in universities in Brazil in the 1990s and 2000s. Students first chose a single major and then took exams that select them in or out of the chosen major. The literature analyzing student...

This paper presents a cheap-talk one-sender-multiple-receiver model in which audiences freeride on each other in the context of global environmental protections. The sender observes the magnitude of damage of emission, and sends the same message simultaneously to all audiences, who then play a...

This paper studies shareholder engagement in companies' strategic decisions. Differences of objective among shareholders arise in our model due to the presence of socially responsible investors. These investors take externalities into account when valuing their portfolio while conventional...

We provide a method allowing identification of margins in an oligopoly price competition game when prices may not be freely chosen in some markets, for example due to regulation. We use our identification strategy to study the effects of regulatory constraints in the pharmaceutical industry. We...

We show that between intensive and extensive farming, the production method most beneficial to biodiversity depends on the equilibrium of agricultural markets. All other things equal, as long as demand reacts to prices and extensive farming has higher production costs, extensive farming tends to...

The growing importance of shared networks, shared platforms and shared standards leads to a renewed discussion of the essential facilities doctrine of antitrust. This is an area where European law and American law have diverged. In Trinko (2007), the U.S. Supreme Court came close to abolishing...

We address the question of measuring and testing industrial spatial concentration based on micro-geographic data with distance based methods. We discuss the basic requirements for such measures and we propose four additional requirements. We also discuss the null assumptions classically used for...

We consider the decentralized provision of a global public good with local external- ities in a spatially explicit model. Communities decide on the location of a facility that benefits everyone but exhibits costs to the host and its neighbors. They share the costs through transfers. We examine...
