Kerem Cosar studies international trade and macroeconomics. His research interests include labor market effects of globalization, economic geography and firm-level empirical analysis of international trade. In this recent research, he used spatial data from Europe to quantify the effects of borders and distance on competition and market shares.

Cosar earned his PhD in economics from The Pennsylvania State University after receiving BA and MA degrees, respectively in management and economics, from Bogazici University in Istanbul, Turkey. Prior to joining Chicago Booth, Cosar taught international economics at the undergraduate level while pursuing his graduate studies. Additionally, he was awarded a Graduate Student Award by the National Science Foundation while at The Pennsylvania State University to participate in the Nobel Laureates Meetings at Lindau, Germany.

At Booth, he teaches Managing the Firm in the Global Economy. He believes that students taking his class will later make managerial decisions in situations that involve the interaction of firms, governments, and workers in an increasingly international marketplace. Therefore, he wants to demonstrate to them a framework for understanding the objectives and responses of these actors, and the consequences of their decisions.

Outside the classroom, he enjoys reading about history, playing and watching sports, and going to concerts.

History, architecture, basketball.

REVISION: Borders, Geography, and Oligopoly: Evidence from the Wind Turbine Industry
Date Posted: Aug  20, 2011
Using a micro-level dataset of Danish and German wind turbine installations, we estimate a structural oligopoly model with cross-border trade and heterogeneous firms. Our approach allows us to separately identify border-related variable costs from distance-related variable costs, and to put bounds on fixed costs of exporting. We find that the variable border costs are large, equivalent to 400 kilometers (250 miles) in transport costs. Counterfactual analysis shows that the fixed costs are also i

REVISION: Human Capital, Technology Adoption and Development
Date Posted: Jan  27, 2009
This paper presents a model of development in which skilled labor is an input in technology adoption. The model combines Nelson and Phelps (1966) type technology dynamics with a growth model in which intermediate goods are used to produce a final good. The intermediate good producers hire skilled labor to increase their productivity by adopting techniques from an exogenously evolving stock of world knowledge. I solve for the stationary equilibrium and derive analytic expressions for steady st
