The extent to which income inequality and poverty vary within countries across different regions is very relevant for policy decisions and monitoring. However, sub-national measures are scarce, given the complexity of producing indicators at the regional level from the available data and the...

The migration of young Chinese scientists to undertake graduate studies in U.S. universities is arguably one of the most important recent episodes of skilled migration. Using a new data set covering around 16,000 Ph.D. graduates in 161 U.S. chemistry departments, we show that Chinese students...

Important gender gaps in entrepreneurship exist. Men are three times more likely than women to own a business with employees. Women rarely own large businesses and their average earnings from selfemployment are up to 60% lower than for men. Cultural norms, stereotypes and lack of role models...

This paper presents recent work undertaken at the OECD to produce environmental indicators at the regional level from geographic data sources. New indicators have been tested and produced in five different domains: a) land cover, b) forest ecosystems, c) urban density, d) CO2 emissions, e) air...

This paper investigates the presence of a network externality which might explain the persistence of low schooling achievements among internal migrants. A simple analytical framework is presented to show how an initial human capital disparity between migrants and non migrants can translate into...

Immigration is rapidly changing the composition of the R&D workforce in the United States. We study here Chinese chemists and chemical engineers who migrate to the United States for their graduate studies. We analyze productivity at the individual researcher level, thus bypassing the...

This paper provides evidence on the links between productivity and internationalisation choices for a large sample of both large and small-medium sized Italian firms. By using detailed qualitative and quantitative information we first identify those firms engaged in international activities...

The number of preferential trade agreements has greatly increased over the past two decades, yet most existing bilateral arrangements take the form of free trade areas, and less than ten percent can be considered to be fully fledged customs unions. This paper develops a political economy model...
