Recent advances in information technologies allow firms to collect vast amounts of detailed personal information on customers and to engage in potentially profitable trade of their information assets. We are interested in the incentives of competing firms to share information if firms can...

In this paper, we propose a tractable variant of the open economy neoclassical growth model that emphasizes political economy and contracting frictions. The political economy frictions involve disagreement and political turnover, while the contracting friction is a lack of commitment regarding...

We investigate in this paper the theory and econometrics of optimal matchings with competing criteria. The surplus from a marriage match, for instance, may depend both on the incomes and on the educations of the partners, as well as on characteristics that the analyst does not observe. Even if the...

In this paper, we propose a method to evaluate the effect of a counterfactual change in the marginal distribution of a single covariate on the unconditional distribution of an outcome variable of interest. We show that such effects are point identified for continuously distributed regressors under...

In a model with heterogeneous-risk-aversion agents facing margin constraints, we show how securities’ required returns are characterized both by their betas and their margins. Negative shocks to fundamentals make margin constraints bind, lowering risk-free rates and raising Sharpe ratios of risky...

Certification is meant to solve the adverse selection problem raised by unsubstantiated claims from firms about environmental safety. Things are getting complicated by the suspicion of uninformed consumers that the certification agency might manipulate their beliefs. To make her certification...

"Strategic models of oligopolistic behavior are highly appreciated by both academia and public decision makers for describing a wide number of industries. In particular, this holds for modern wholesale electricity markets, which are often highly concentrated, and consequently several competing...

The concept of causality is naturally defined in terms of conditional distribution, however almost all the empirical works in this literature focus on the causality in the mean. This paper aims to propose a different nonparametric statistic to test the conditional independence and Granger non-...

We consider a formal approach to comparative risk aversion and apply it to intertemporla choice models. This makes it possible to investigate whether standard classes of utility functions, such as those inspired from Khilstrom and Mirman (1974), Selden (1978), Epstein and Zin (1989) or Quiggin (...
