Este texto estima os retornos educacionais e diferenciais raciais na distribuição de salários das mulheres no Brasil, usando regressão quantílica com correção semiparamétrica para viés de seleção amostral. As estimativas mostram que os retornos educacionais são elevados e que não...

In this note, we suggest a link between tariff protection and firms' incentives to engage in a horizontal merger. We consider a Cournot oligopoly with equal, constant marginal costs where firms have to decide on lobbying efforts prior to choosing output. These lobbying efforts will determine...

We test the empirical effectiveness of two theoretical proposals to equilibrate bargaining power in bilateral bargaining. Our experimental design is based on the two-player versions of the multibidding game (Pérez-Castrillo & Wettstein, 2001) and the bid-and-propose game (Navarro & Perea,...

I analyse monopoly pricing and quality decisions under network effects. High quality premium and low quality punishment are found to depend on how the impact of marginal costs on quality relates to the intensity of the network effect and the optimism of the producer about final demand. More...

I consider situations in which a group of players extracts a value if they organise themselves in different network structures, and I define a solution concept to describe the decentralised decision that determines the network formation process and the allocation of the value. I demonstrate that...

I analyze a market where there is a homogeneous good, which quality is chosen, and therefore known, by a single producer. Consumers do not know the quality of the good but they use their acquaintances in order to obtain information about it. Information transmission exhibits decay and consumers...

I propose three modifications of Jackson's flexible network axiom (Jackson, 2005) when the structure of externalities across components have been identified. The first one takes into account the information about the externalities across components. The second one allows for coalitional...

We consider situations where the cooperation and negotiation possibilities between pairs of agents are given by an undirected graph. Every connected component of agents has a value, which is the total surplus the agents can generate by working together. We present a simple, sequential, bilateral...
