We study the relationship between offshoring and job stability in Italy in the period 1995–2001 by using an administrative dataset on manufacturing workers. We find that the international fragmentation of production negatively affects job stability. Service offshoring and material purchases...

The present contribution deals with models and statistical analysis of sequences of random events. The main characteristics of such a random point process is its intensity. We consider the case when observed data are grouped, i.e. when the numbers of observed events are summarized in discrete...

We estimate a general microstructure model of the transitory and permanent impact of order flow on stock prices. Jumps are detected in both the transaction price (observation equation) and fundamental value (state equation). The model's parameters and variances are updated in real time. Prices...

I expose the risk of false discoveries in the context of multiple treatment effects. A false discovery is a nonexistent effect that is falsely labeled as statistically significant by its individual t-value. Labeling nonexistent effects as statistically significant has wide-ranging academic and...

This paper presents a new estimator for the mixed proportional hazard model that allows for a nonparametric baseline hazard and time-varying regressors. In particular, this paper allows for discrete measurement of the durations as happens often in practice. The integrated baseline hazard and all...

This paper implements a method to identify and estimate treatment effects in a dynamic setting where treatments may occur at any point in time. By relating the standard matching approach to the timing-of-events approach, it demonstrates that effects of the treatment on the treated at a given...

In a large class of hazard models with proportional unobserved heterogeneity, the distribution of the heterogeneity among survivors converges to a gamma distribution. This convergence is often rapid. We derive this result as a general result for exponential mixtures and explore its implications...

The objective of the article has consisted of a cross-sectional and longitudinal analysis of the economic poverty state during the period 1985-1995, using the Panel Household Budget Survey for this period of time. The three aspects of poverty incidence, intensity and inequality in the left tail...

We evaluate the effect of active labour market programs on the duration of unemployment in a reward or punish system. In Switzerland, unemployment benefits are conditional upon program attendance after 7 months of unemployment duration. In the evaluation we allow for selectivity affecting the...
