December 2011Employment Protection Legislation and Plant-Level Productivity in India
with Verónica C. Frisancho Robles, Kala Krishna: w17693
Using plant-level data from the Annual Survey of Industries (ASI) for the fiscal years from 1998-99 through 2007-08, this study provides plant-level cross-state/time-series evidence of the impact of employment protection legislation (EPL) on total factor productivity (TFP) and labor productivity in India. Identification of the effect of EPL follows from a difference-in-differences estimator inspired by Rajan and Zingales (1998) that takes advantage of the state-level variation in labor regulation and heterogeneous industry characteristics. The fundamental identification assumption is that EPL is more likely to restrict firms operating in industries with higher labor intensity and/or higher sales volatility. Our results show that firms in labor intensive or more volatile industries benefite...

January 2007International Comparisons of R&D Expenditure: Does an R&D PPP Make a Difference?
with Robert Inklaar, Robert H. McGuckin, Bart van Ark: w12829
Purchasing power parities (PPPs) for R&D expenditure in 19 manufacturing industries are developed for France, Germany, Japan, the Netherlands and the United Kingdom relative to the United States for the years 1997 and 1987. These PPPs are based on R&D input prices for specific cost categories and differ substantially from current practice of comparing R&D expenditure using GDP PPPs and deflators. After taking into account differences in the relative price of R&D labor and materials, separate PPPs for other R&D cost categories are less essential, and a simpler version using GDP PPPs for these other categories should suffice. Our preferred PPPs are used to compare international R&D costs and intensity. The results suggest that the efforts devoted to R&D in each country are more similar acros...
