In this paper, we analyse the effectiveness of the direct central bank interventions using a new effectiveness criterion. To this aim, we investigate the effects of central bank interventions (CBI) in a noise trading model with chartists and fundamentalists. We first estimate a model in which...

Recent theoretical studies suggest that migration prospects can raise the expected return to human capital and thus foster education investment at home or, in other words, induce a brain gain. In a recent paper (Beine, Docquier and Rapoport, Economic Journal, 2008) we used the Docquier and...

Migration flows are shaped by a complex combination of self-selection and out-selection mechanisms. In this paper, we analyze how existing diasporas (the stock of people born in a country and living in an another one) affect the size and human-capital structure of current migration flows. Our...

This paper empirically investigates the main determinants of secret interventions in the foreign exchange (FX) market. Using the recent experience of the Bank of Japan, we estimate a model that explains the share of secret to reported interventions in the FX market. Two sets of determinants are...

Intervening in the FX market implies a complex decision process for central banks. Monetary authorities have to decide whether to intervene or not, and if so, when and how. Since the successive steps of this procedure are likely to be highly interdependent, we adopt a nested logit approach to...

Using new data on emigration rates by education level, we examine the impact of brain drain migration on human capital formation in developing countries. We find evidence of a positive effect of skilled migration prospects on gross human capital formation in a cross-section of 127 countries. For...

In this paper, we investigate through Monte Carlo simulations the behavior of the codependence testing procedure (Gouriéroux et Peaucelle [1989]) in small samples and in various usual statistical situations. Our results suggest that, except for the pure MA(q) case, important power losses may...

In this paper we study the role of official statements and speeches given by central bank authorities in charge of foreign exchange policy. We investigate the impact of statements that comment on and confirm such interventions on the day of the intervention on the two major foreign exchange...
