In this paper we use panel data models and quantile regressions to test the "weak" and "strong" versions of the Porter hypothesis, using data from 14 OECD countries over the period 1990-2011. A newly-released environmental policy stringency index (EPS) provided by the OECD is used as an...

The beginning rise in obesity prevalence rates in South Africa was first noticed already in the early 1990s. Since then, several articles have discussed how the nutrition transition has affected people’s body weights in the country. This article is the first one that uses longitudinal data...

This paper presents a theoretical gravity model of trade in which foreign aid is considered as a transfer instead of being part of the trade cost, as it has been previously done in the related literature. We argue that the usual specification leads to invalid out-of-sample predictions, biased...

International fragmentation of production and economic integration change the structure of international trade. Novel datasets reveal how production processes are unbundled across borders and connected internationally through Global Value Chains (GVCs). Yet, the impact of Economic Integration...

The issues of zero trade observations and the validity of the log linear transformation of the gravity equation have generated a number of debates in the literature with differing claims about the most suitable estimation technique. To produce unbiased and consistent estimates for policy making,...

Using bilateral data on remittance flows to Pakistan for 23 major host countries, this is the first study that examines the effect of transaction costs on foreign remittances. The authors find that the effect of transaction costs on remittance flows is negative and significant; suggesting that a...
