August 2017The Rise of Market Power and the Macroeconomic Implications
with Jan De Loecker: w23687
We document the evolution of markups based on firm-level data for the US economy since 1950. Initially, markups are stable, even slightly decreasing. In 1980, average markups start to rise from 18% above marginal cost to 67% now. There is no strong pattern across industries, though markups tend to be higher, across all sectors of the economy, in smaller firms and most of the increase is due to an increase within industry. We do see a notable change in the distribution of markups with the increase exclusively due to a sharp increase in high markup firms. We then evaluate the macroeconomic implications of an increase in average market power, which can account for a number of secular trends in the last 3 decades: 1. decrease in labor share, 2. increase in capital share, 3. decrease in low sk...
December 2007Occupational Choice and Development
with Boyan Jovanovic: w13686
The rise in world trade since 1970 has raised international mobility of labor services. We study the effect of such a globalization of the world's labor markets. We find that when people can choose between wage work and managerial work, the output gains are U-shaped: A worldwide labor market raises output by more in the rich and the poor countries, and by less in the middle-income countries. This is because the middle-income countries experience the smallest change in the factor-price ratio, and where the option to choose between wage work and managerial work has the least value in the integrated economy. Our theory also establishes that after economic integration, the high skill countries see a disproportionate increase in managerial occupations. Using aggregate data on GDP, openness and ...

December 1998Inequality
with Boyan Jovanovic: w6841
In a growth model, rent-grabbing and free riding can give rise to inequality in productivity and firm size. Inequality among firms affects a firm's incentive to free ride or to grab rents, and, hence, the incentive to invest in research and training We follow Lucas and Prescott (1971) and Hayashi (1982) and assume constant returns in production and in adjustment costs for investment, and perfect capital markets. Our conclusion, however, differs starkly from theirs: Average Tobin's q generally exceeds marginal q. That is, the unit value of capital is lower in big firms, and evidence dating back to Fazzari, Hubbard, and Petersen (1988) supports this claim quite decisively. Such evidence is usually taken to imply that small firms invest at a rate lower than its perfect capital market rate. ...
