We develop a methodology for identifying departures from relative factor price equality across regions that is valid under general assumptions about production, markets and factors. Application of this methodology to the United States reveals substantial and increasing deviations in relative...

When multiple durations are generated by a single unit, they may be related in a way that is not fully captured by the regressors. The omitted unit-specific variables might vary over the durations. They might also be correlated with the variables in the regression compenent. We propose an...

In the second half of the 1990s Switzerland introduced an ambitious active labour market policy (ALMP) encompassing a variety of programmes. We evaluate the effects of these programmes on individual employment probability using unusually informative data originating from administrative records....

Transferring low tech manufacturing jobs to cheap labour countries is often seen by part of the general public and policy makers as a step into the de-industrialisation of the European economies. However, several recent contributions have shown that the effects on home economies are rarely...

This Paper presents a methodology to identify net demand shocks as well as wage rigidities in heterogeneous labour markets on the basis of nonparametric regression. We show how this approach can be used to make suggestions for immigration policy in economies with labour market rigidities. In an...

What is the relationship between economic growth and its volatility? Does political instability affect growth directly or indirectly, through volatility? This paper tries to answer such questions using a power-ARCH framework with annual time series data for Argentina from 1896 to 2000. We show...

Hurst (1951) developed Rescaled range analysis to determine long-memory effects and fractal Brownian motion in time series. Rescaled range (R/S) analysis measures how the distance covered by a particle increases as we look at longer and longer time scales. For Brownian motion the distance...

Cet article fournit quelques resultats de previsions de pics de pollution d'ozone pour la station de mesure de Vitrolles, situee dans l'Aire Metropolitaine Marseillaise. Nous presentons d'abord la methode de regression par arbre et une idee de stabilisation par Agregatopm par Bootstrap. Ces...

The basic idea in this paper is that labor supply can be viewed as a function of the entire budget set, so that one way to account non-parametrically for a nonlinear budget set is to estimate a nonparametric regression where the variable in the regression is the budget set. In the special case...
