July 2011China and India as Suppliers of Affordable Medicines to Developing Countries
with David Popp: w17249
As countries reform their patent laws to be in compliance with the Trade Related Intellectual Property Rights Agreement, an important question is how increased patent protection will affect drug prices in low-income countries. Using pharmaceutical trade data from 1996 to 2005, we examine the role of China and India as suppliers of medicines to other middle- and low-income countries and evaluate the competitive effect of medicine imports from these countries on the price of medicines from high- income countries. We find that imports of antibiotics and unspecified medicaments from India and China significantly depress the average price of these commodities imported from high-income trading partners, suggesting that India and China are not only important sources of inexpensive medicines but a...
September 2007Policy vs. Consumer Pressure: Innovation and Diffusion of Alternative Bleaching Technologies in the Pulp Industry
with David Popp, Nick Johnstone: w13439
In the late 1980s and early 1990s, concern over dioxin in both paper products and wastewater led to the development of techniques that reduced the use of chlorine in the pulp industry. Both regulatory and consumer pressure motivated this change. We use patent data to examine the evolution of two completing bleaching technologies in five major paper-producing countries, both of which reduce the use of chlorine in the pulping process. By the end of the 1990s, nearly all pulp production in these countries used one of these technologies. Unlike other papers using patents to study environmentally-friendly innovation, we focus on a process innovation, rather than on end-of-the-pipe solutions to pollution. Moreover, while previous studies emphasize the importance of regulation for inducing innova...
