We set up a formal framework to characterize encompassing of nonparametric models through the distance. We contrast it to previous literature on the comparison of nonparametric regression models. We then develop testing procedures for the encompassing hypothesis that are fully nonparametric. Our...

We study a two-period industry where firms are run by agents privately informed about their (persistent) costs, and principals can only use spot contracts. We characterize novel semi-separating equilibria where principals randomize in one or both periods. These equilibria have the following...

In an investment experiment, we show variations in information affect belief and decision behaviors within the information-beliefs-decisions chain. Subjects observe the time series of a risky asset and a signal that, in random rounds, helps predict returns. When they perceive the signal as useless...

Firms receiving independent signals on a common-value risky project compete to be the first to invest. When firms are symmetric and competition is winner-take-all, rents are fully dissipated in equilibrium and the extent to which signals are publicly disclosed is irrelevant for welfare. When...

We develop a bilateral oligopoly framework with manufacturer-retailer bargaining to analyze the impact of retail mergers on market outcomes. We show that the surplus division between manufacturers and retailers depends on three bargaining forces and can be interpreted in terms of an “equilibrium of...
