Log-concave distributions are an interesting and well-behaved nonparametric model. In the first part of the talk we present some fundamental properties of this model and discuss maximum-likelihood estimation based on i.i.d. data. In the second part we discuss potential applications to regression...

This paper uses a microfinance field experiment in two Lima shantytowns to measure the relative importance of social networks and prices for borrowing. Our design randomizes the interest rate on loans provided by a microfi- nance agency, as a function of the social distance between the borrower and...

This paper shows how the rise in individual income risk in the US since the 1980s might help explain the fall in its foreign asset position. The key to this result is endogenous financial deepening in an open economy with participation-constrained domestic financial markets. More volatile income...

The aim of this paper is to analyze the need for cash and default regulation in nsurance. Proponents of deregulation argue that these requirements are useless as insurers would hold enough cash as soon as policyholders are fully informed about their default probability. Adding to the purpose the...

Capital gains taxes are important sources of government income in particular in high tax Scandinavian countries. Theses taxes, nevertheless, likely distort the market and resource allocations through so called “lock-in” effect by discouraging trade transactions that would trigger the tax payments....

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...
