Efficiency and Ownership Structure – The Case of Poland Karl-Markus Modén, Pehr-Johan Norbäck and Lars Persson

We examine the effects of foreign entry on productive efficiency during the Polish investment liberalization. The performance of foreign acquisitions is compared to foreign firms entering the market through greenfield entry, as well as domestic acquisitions of privatized firms, domestic greenfields and remaining state-owned (non-privatized) firms during the period 1995-2000. We find that foreign privatized firms have realized larger productivity gains than all types of domestic firms and that this is not due to higher price-cost margins, which is consistent with the idea that foreign firms bring in firm-specific knowledge. Foreign greenfields have the highest average labour productivity, while foreign privatizations show the largest productivity increase.

An Introduction to the Relationship between Inequality and Health

Sick of Inequality.jpg

In this book Andreas Bergh, Therese Nilsson, IFN and Lund University, and Daniel Waldenström, IFN and Paris School of Economics, France, review the latest research on the relationship between inequality and health. What does inequality mean for our health? Does increasing income inequality affect outcomes such as obesity, life expectancy and subjective well-being?


Seminars organized by IFN


To present ongoing research informal brown-bag seminars are held on Mondays at 11:30 am. This is an opportunity for IFN researchers to test ideas and results.

Academically oriented seminars are most of the time held on Wednesdays at 10 am. At these events researchers from IFN and other institutions present their research.

In addition, IFN organizes seminars open to the public. Topics for these are derived from the IFN research.
