What makes a good valuable are not only its intrinsic characteristics but also the image associated with it. I model quality provision by a monopolist when consumers have private information about their preference for quality and their image concern. Image concerns never increase the total amount...

In this paper, we study the exponential utility maximization problem in an incomplete market with a default time inducing a discontinuity in the price of stock. We first consider the case of strategies valued in a compact set. Using a verification theorem, we prove that the value function...

We use detailed information on labor earnings and employment from Social Security records to document the evolution of earnings inequality in Spain in the last two decades. As is common in administrative records, our measure of labor earnings is top and bottom-coded. We compare the prediction...

We propose a unified framework for defining measures of industrial concentration based on micro-geographic data. These encompass the Duranton-Overman and the Marcon-Puech indices. We discuss the basic requirements for such measures introduced by Duranton and Overman (2005) and we propose five...

The idea that there exists a trade-off between robustness and the extent to which certain goals of mechanism design can be achieved is intuitive. Nonetheless, the literature on robust mechanism design is silent about it. We explore the problem in the context of an efficient auction problem with...

We investigate the hypothesis that macroeconomic fluctuations are primitively the results of many microeconomic shocks, and show that it has significant explanatory power for the evolution of macroeconomic volatility. We define “fundamental” volatility as the volatility that would arise from an...

We propose a simple theory of labelling for goods with a credence aspect. Provision of labels can be seen as a public good. We employ a tournament to provide a ranking of goods (or services) with a credence aspect to the uninformed public. The theory seems to be similarly applicable to advertising...

We build up a model where a mass of heterogenous commuters has to choose between public transportation and the car. Our main assumption comes from cross modal externalities: depending on the policy implemented, the congestion generated by car affects the quality of public transportation. We show...

This paper focuses on the analysis of the extent to which air traffic is affected by the proposal of the European Commission on including the aviation sector into the European emission trading scheme and the increasing fuel prices by using a panel data of 18 European Airlines from 1990 through 2007...
