Two duopolists compete in price on the market for a homogeneous product. They can ‘profile’ consumers, i.e., identify their valuations with some probability. If both firms can profile consumers but with different abilities, then they achieve positive expected profits at equilibrium. This...

This paper analyzes dynamic equilibrium risk sharing contracts between profit-maximizing intermediaries and a large pool of ex-ante identical agents that face idiosyncratic income uncertainty that makes them heterogeneous ex-post. In any given period, after having observed her income, the agent...

The availability of quantity information along with expenditure information in some household surveys allows the estimation of price reactions on the basis of unit values. We compare two specifications that have been proposed in this context by Deaton (1990) and Crawford et al. (1997) in order...

This paper models the competition of user networks as a continuous-time Markov process. It presents a dynamic version of the Discrete Choice Analysis with state-dependent choice probabilities. Among other things, we show that the network competition can be characterized by the coexistence of...

Reinforcement learning theory has produced important insights into economic behavior. Intriguingly, neuroscientists recently discovered a plausible mechanism through which reinforcement may be encoded in the brain. Yet their resulting quot;dopaminergic reward prediction errorquot; hypothesis has...

In this paper we revisit the literature on the economic consequences from inefficiency in public services provision. Following Dupuit (1844) and Pigou (1947) we argue that it is important to take the financing side explicitly into account. The fact that public expenditure financing must rely on...

In product markets, there exists substantial dispersion in prices for transactions of physically identical goods, and incumbent sellers sell at higher prices than entrants. This study develops a theory of dynamic pricing that explains these facts as results from the same fundamental friction:...

Portuguese Abstract: Exploramos vários jogos diferenciais para simular a competição entre duas firmas em Preço, Publicidade, e Preço e Publicidade simultâneamente. Os resultados reforçam conclusões importantes na literatura e complementam-na, permitindo analisar a competição em dois...

The primary means of enforcement of legal liabilities is through the seizure of debtors' assets. However, debtors can shield their assets in various ways and thereby reduce the power of enforcement. This paper studies the circumstances under which a debtor would choose to shield assets and the...
