Non-compliance with medication therapy remains an unsolved and expensive problem for health care systems around the world. Yet we know little about the factors that determine a patient's decision to follow treatment recommendations. This study uses a unique panel dataset comprising all...

This article is an empirical application of the search model with an unknown distribution, as introduced by Rothschild in 1974. For searchers who hold Dirichlet priors, we develop a novel characterization of optimal search behavior. Our solution delivers easily computable formulas for the...

When consumers search for differentiated products, a given search decision can be explained either by low search cost or by low tastes for the set of products already found. We propose an identification strategy that allows to estimate the search cost distribution in the presence of unobserved...

We study price competition in markets with a large number (in magnitude of hundreds or thousands) of potential competitors. We address two methodological challenges: simultaneity bias and high dimensionality. Simultaneity bias arises from joint determination of prices in competitive markets. We...

We study vertical integration in the form of financial ownership as a way to improve the bargaining position of a firm in sequential negotiations. In our model an upstream monopolist bargains sequentially with two downstream firms over production agreements. If the bargaining sequence is...

In this paper, we revisit the problem of search with learning about the price distribution, as introduced by Rothschild (1974). For searchers with Dirichlet priors, we develop a novel characterization of the optimal search behavior. The advantage of our solution relative to the characterization...
