April 2015An Empirical Examination of Patent Hold-up
with Alexander Galetovic, Ross Levine: w21090
A large literature asserts that standard essential patents (SEPs) allow their owners to “hold up” innovation by charging fees that exceed their incremental contribution to a final product. We evaluate two central, interrelated predictions of this SEP hold-up hypothesis: (1) SEP-reliant industries should experience more stagnant quality-adjusted prices than similar non-SEP-reliant industries; and (2) court decisions that reduce the excessive power of SEP holders should accelerate innovation in SEP-reliant industries. We find no empirical support for either prediction. Indeed, SEP-reliant industries have the fastest quality-adjusted price declines in the U.S. economy.
January 2013These Are the Good Old Days: Foreign Entry and the Mexican Banking System
with Aldo Musacchio: w18713
In 1997, the Mexican government reversed long-standing policies and allowed foreign banks to purchase Mexico's largest commercial banks and relaxed restrictions on the founding of new, foreign-owned banks. The result has been a dramatic shift in the ownership structure of Mexico's banks. For instance, while in 1991 only one percent of bank assets in Mexico were foreign owned, today they control 74 percent of assets. In no other country in the world has the penetration of foreign banks been as rapid or as far-reaching as in Mexico. In this work we examine some of the important implications of foreign bank entry for social welfare in Mexico. Did liberalization lead to an increase (or decrease) in the supply of credit? Did liberalization lead to an increase (or decrease) in the cost of credit...
November 1996The Efficiency Consequences of Institutional Change: Financial Market Regulation and Industrial Productivity Growth in Brazil, 1866-1934
This paper examines one of the central hypotheses of the New Institutional Economics: that the reform of institutions--the rules and regulations enforced by the State that both permit and bound the operation of markets--is crucial for the process of economic growth. It examines this hypothesis by estimating the productivity gain afforded to Brazilian textile firms by the reform of the regulations governing Brazil's securities markets in 1890. This analysis is based on panel data regressions on 18 firm-level censuses covering the period 1866-1934, which permit me to decompose total factor productivity growth. These censuses cover both limited liability joint stock corporations as well as privately owned firms. I also analyze corporate financial statements and stock market data for public...
