Social Ties and Subjective Performance Evaluations: An Empirical Investigation

Breuer, Kathrin; Nieken, Petra; Sliwka, Dirk - Institute for the Study of Labor (IZA) - 2010

The Value of Peripatetic Economists: A Sesqui-Difference Evaluation of Bob Gregory

Hamermesh, Daniel S. - Institute for the Study of Labor (IZA) - 2005

I ask generally whether a country can benefit from the temporary importation of human capital, and specifically whether a program that attracts large groups of academic visitors to a distant country benefits it by generating additional scholarly research on local issues. Using the list of...
