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

This paper reviews the existing literature on the impact of migrants networks on the patterns of international migration. It covers the theoretical channels at stake in the global effect of the networks. It identifies the key issues, namely the impact on size, selection and concentration of the...

This paper, exploiting the properties of mixed causal and noncausal models, proposes strategies to detect time reversibility in stochastic processes. These novel strategies can be implemented to verify the time reversibility of stationary stochastic processes. We show that they can also be used...

This study expands the empirical specification of Cerra and Saxena (2008), and allows short-termoutput growth regimes to be determined by globalization. Relying on a non-linear dynamic panelrepresentation, it reconciles the earlier results in the literature regarding the two oppositenarratives...

Commodity price booms, as those recorded in the last decade, may have a significant economic impact in small, commodity exporting, developing countries. Whether the impact on output is positive or negative is still unclear. It depends on various factors, notably on the impact that commodity...

In recent years, the Credit Rating Agencies (“CRAs”) have been in the eye of the storm. Some argue that CRA rating errors — symptomatized by rating inflation or deflation — originate in excessive competition. This paper argues that the low level of competition in credit rating is a...
