Using longitudinal employer-employee data spanning over a 22-year period, we compare age-wage and age-productivity profiles and find that productivity increases until the age range of 50-54, whereas wages peak around the age 40-44. At younger ages, wages increase in line with productivity gains...

In this paper we use a novel approach and a large Portuguese employer-employee panel data set to study the hypothesis that industrial agglomeration improves the quality of the firm-worker matching process. Our method makes use of recent developments in the estimation and analysis of models with...

This article re-examines the relationship between industry localization and the employment size of establishments. To measure localization, we use an approach that builds on Ellison and Glaeser's (, Journal of Political Economy, 105: 889-927) dartboard location model. Our localization index is...

This paper analyzes the early research performance of PhD graduates in labor economics, addressing the following questions: Are there major productivity differences between graduates from American and European institutions? If so, how relevant is the quality of the training received (i.e....

Given the recent efforts in several countries to reorganize the research institutional setting to improve research productivity, our analysis addresses the following questions: To which extent has the recent awareness over international quality standards in economics around the world been...

A simultaneous price-setting oligopoly game characterized by the existence of buyers with differing price information is presented. The information structure of the game is more general than previously considered, thereby permitting a richer analysis. In addition to identifying the general...

In this paper I analyze the state of Portuguese research in Economics based on publications in international journals for the period of 1986 to 2000. I find that scientific production is increasing but productivity remains low. I also provide a revealing characterization of the production habits...

In this article, I derive a score test for the equality of one or more parameters across groups of observations following estimation of a single-index model. The test has a wide array of applications and nests Pearson’s chi-squared test as a particular case. The postestimation command scoregrp...
