Última Imperfect Competition and Total Factor Productivity Growth in U.S. Food Processing AgEcon Azzam, Azzeddine M.; Lopez, Elena; Lopez, Rigoberto A.. This article examines the role of imperfect competition in determining total factor productivity growth (TFPG) by bringing together a New Empirical Industrial Organization (NEIO) model and the TFPG model of Nadiri and Mamuneas (1998). Applying the integrated model to 1973-92 data from 29 food processing industries revealed that changes in markups, economies of scale, and demand growth contributed positively to TFPG while the disembodied technical change was a negative contributor. Furthermore, the TFPG estimates are starkly different from the conventional (Solow's residual) TFPG measures, underscoring the need to account for imperfect competition, returns to scale, and demand in analyses of this type.

Ano: 2002 URL: http://purl.umn.edu/25147 The Impact of Imports on Price-Cost Margins: An Empirical Illustration AgEcon Lopez, Rigoberto A.; Lopez, Elena. This article decomposes the impact of imports on domestic price-cost margins into separate price and cost effects. Using data from 24 food-processing industries, the empirical results show that although the direct impact of imports on prices is always negative, a positive net impact on price-cost margins occurs in industries characterized by low own-price elasticity of demand and diseconomies of scale. Further results show that the disciplining effect of imports is more preponderant the lower the degree of domestic competition.
