We develop a theoretical model to investigate whether short-term mobility differentially affects innovation in product or process and carry out an empirical analysis with a focus on Africa using firm-level data from the World Bank Enterprise Survey, as well as complementary country level...

This paper studies the educational investment decisions of returning migrants while abroad in the context of their decisions about the choice of activity upon returning and the duration of migration. The theoretical model builds on Dustmann (1999), Dustmann and Kirchkamp (1992) and Mesnard...

This paper contributes to existing work on innovation by studying the determinants of various types of interaction between a firm and its external environment. In particular, it focuses on face-to-face interactions carried out through international business visits. The results indicate that...

In this paper, we aim to shed light on the relative contribution of the separation and job finding rates to French unemployment at business cycle frequencies by using administrative data on registered unemployment and labor force surveys. We first investigate the fluctuations in steady state...

We propose a novel selectivity correction procedure to deal with survey attrition, at the crossroads of the "Heckit" and of the bounding approach of Lee (2009). As a substitute for the instrument needed in sample selectivity correction models, we use information on the number of attempts that...

This paper evaluates the impact of an unexpected temporary hiring credit targeted at workers paid below 1.6 times the minimum wage in firms with less than 10 employees in France from December 2008 to December 2009. Using rich administrative data covering all French firms, we find that the...

This paper studies whether skilled migrants contribute to the host country's 'productive efficiency' (Farrell, 1957) using input-output and immigration sectoral data for seven industries in twelve countries during the period 1999-2001. We find that skilled migrants contribute positively to a...

This paper analyzes the effectiveness of hiring credits. Using comprehensive administrative data, we show that the French hiring credit, implemented during the Great Recession, had significant positive employment effects and no effects on wages. Relying on the quasi-experimental variation in...

This paper contributes a theoretical model to study the effects of short-term movements of skilled labour on a country's economic growth. As traditional migration models emphasise the long-term effects of migration on factor endowments, they typically omit the analysis of gross labour flows....
