The paper investigates the patterns of persistence of innovation and of the properties of firms' knowledge base (KB) across a sample of Italian firms in the period 1998-2006. The analysis draws upon a theoretical representation of knowledge as a collective good, stemming from the recombination...

We develop a reliable Bayesian inference for the RIF-regression model of Firpo, Fortin and Lemieux (Econometrica, 2009) in which we first estimate the log wage distribution by a mixture of normal densities. This approach is pursued so as to provide better estimates in the upper tail of the wage...

We estimate the informal-formal sector pay gap throughout the conditional wage distribution using panel data from Brazil, Mexico and South Africa. We control for time-invariant unobservables and identification is stemming from inter-sector movers. We control for observables in a non-linear way...

In this paper, we propose a variance reduction method for quantile regressions with endogeneity problems. First, we derive the asymptotic distribution of two-stage quantile estimators based on the fitted-value approach under very general conditions on both error terms and exogenous variables....

Large changes in marital trends during the second half of the 20th century raise the question of the reason leading to marriage in Western Europe and in Northern America: declining marriage rates, increase in cohabitation, increasing divorce rates. But the reason to get married can be diverse...

Innovation is commonly seen as the principal engine of economic development. In this paper, we investigate the microfoundations of economic growth by relating innovation to sales growth at the firm-level, for incumbent firms in four «complex technology» sectors. The average firm, which...
