|November 2013||Price and Quality Dispersion in an Offshoring Market: Evidence from Semiconductor Production Services|
with David Byrne, Brian K. Kovak: w19637
This paper studies price and quality differences across international intermediate input suppliers. We develop price measures that account for (i) differences in product characteristics, (ii) unobserved quality differences, and (iii) pure (frictional) price dispersion across suppliers. Using uniquely detailed transaction- level data from the semiconductor industry, we document large average price differences across suppliers for observationally identical products, and find that price differentials close over the product life cycle. We interpret this finding in a model where buyers face costs of switching suppliers. The theory demonstrates how to use the observed price dynamics to adjust prices for unobserved quality differences across suppliers. The results of this analysis reveal tha...
|January 2007||The Ins and Outs of Cyclical Unemployment|
with Michael W. Elsby, Gary Solon: w12853
One of the strongest trends in recent macroeconomic modeling of labor market fluctuations is to treat unemployment inflows as acyclical. This trend stems in large part from an influential paper by Shimer on "Reassessing the Ins and Outs of Unemployment," i.e., the extent to which increased unemployment during a recession arises from an increase in the number of unemployment spells versus an increase in their duration. After broadly reviewing the previous literature, we replicate and extend Shimer's main analysis. Like Shimer, we find an important role for increased duration. But contrary to Shimer's conclusions, we find that even his own methods and data, when viewed in an appropriate metric, reveal an important role for increased inflows to unemployment as well. This finding is furth...
