This paper provides new evidence on the wage gap between informal and formal salary workers in South Africa, Brazil and Mexico. We use rich datasets that allow us to define informality in a relatively comparable fashion across countries. We compute precise wage differentials by accounting for...

The paper contributes to the ongoing debate about the adequate technique to identify the impact of immigration. Initially the regression analysis on the basis of education-experience cells reveals that the impact of immigration on native wages in Germany is negative, but small. The subsequent...

This paper studies the convergence process, or lack thereof, of Total Factor Productivity (TFP) for a panel of 13 OECD countries over the period 1979-2007, adding breadth and depth to the convergence debate in the telecommunications industry. TFP growth is examined through the Malmquist Index...

The analysis of crossover designs assuming i.i.d. errors leads to biased variance estimates whenever the true covariance structure is not spherical. As a result, the OLS F-Test for treatment differences is not valid. Bellavance et al. (Biometrics 52:607-612, 1996) use simulations to show that a...

We show that the positive relation between income deprivation and mental health is affected by an individual's non-cognitive skills. Income deprivation is operationalized as the Yitzhaki index, i.e., as a function of the sum of income differences between an individual and others in her reference...
