Helpman, Melitz and Rubinstein (2008) derive gravity equations to estimate effects of trade barriers on the intensive and extensive margins of trade. They exploit the frequency of zeros in aggregate bilateral trade data to identify effects on the extensive margin and to obtain controls for firm...

Actively managed Swedish equity mutual funds outperform the market in 1993‐2001 but have negative gross and net excess returns of ‐0.18 and ‐1.47 per cent per year in 2002‐2013. Across funds, there is no correlation between activism and return in the later period. Returns show little or...

Measured by trade in intermediate inputs, economic integration has increased between 2000 and 2014 between members of the European Union and even more with non-members. Integration is negatively related to economic size and positively to the number of years as a member. Germany is the largest...

We estimate that the euro has increased trade within the eurozone by about 26 percent and trade between the eurozone and outsiders by about 12 percent on average for the years 2002-2005 compared to 1995-1998. The percentage increases were smaller for products that were exported every year during...

This paper discusses political and economic aspects of Turkish accession. Under present rules, Turkey would have the greatest number of council votes within twenty years, and receive the largest budget transfer. Free migration may increase the Turkish immigrant population in Germany from 2 to...
