The Case Against Intellectual Property

American Economic Review 2002 92(2), 209-212 open access
According to a common argument, the presence of strong intellectual property rights spurs innovation, which then leads to fiercer competition, higher economic growth and increasing benefits for the average consumers. We argue that, in the case of intellectual property rights, this has lead to misconceptions and abuses. Current legislation on intellectual property confuses the protection of property rights on objects in which ideas are embodied with the attribution of monopoly power on the idea itself and, furthermore, with restrictions on the usage of such goods on the part of the buyers. This implies that both patent and copyright laws should be dramatically altered. To back up our claim we provide theoretical arguments, even for the most extreme case in which goods are produced at a positive fixed cost and zero marginal cost.

Plant-Level Irreversible Investment and Equilibrium Business Cycles

American Economic Review 2002 92(1), 181-197 open access
This paper evaluates the importance of microeconomic irreversibilities for aggregate dynamics using a real-business-cycle (RBC) model characterized by investment irreversibilities at the establishment level. The main finding is that investment irreversibilities do not play a significant role in an otherwise standard real-business-cycle model: Even though investment irreversibilities are crucial for establishment-level dynamics, aggregate fluctuations are basically the same under fully flexible or completely irreversible investment.

Managing Dynamic Competition

American Economic Review 2002 92(4), 779-797 open access
In many important high-technology markets, including software development, data processing, communications, aeronautics, and defense, suppliers learn through experience how to provide better service at lower cost. This paper examines how a buyer designs dynamic competition among rival suppliers to exploit learning economies while minimizing the costs of becoming locked in to one producer. Strategies for controlling dynamic competition include the handicapping of more efficient suppliers in procurement competitions, the protection and allocation of intellectual property, and the sharing of information among rival suppliers.

The Impact of Economic Conditions on Participation in Disability Programs: Evidence from the Coal Boom and Bust

American Economic Review 2002 92(1), 27-50 open access
We examine the impact of the coal boom of the 1970's and the coal bust of the 1980's on disability program participation. These shocks provide clear evidence that as the value of labor-market participation increases, disability program participation falls. For the Disability Insurance program, the elasticity of payments with respect to local earnings is between -0.3 and -0.4 and for Supplemental Security Income the elasticity is between -0.4 and -0.7. Consistent with a model where qualifying for disability programs is costly, the relationship between economic conditions and program participation is much stronger for permanent than for transitory economic shocks.

Is Equality Stable?

American Economic Review 2002 92(2), 253-259 open access
Economic inequality is of interest not only at some intrinsic level, but also for its close connections to diverse variables, ranging from economic indicators such as growth rates to sociopolitical outcomes such as collective action and conflict.It is only natural, then, to study the evolution of inequality in an economic system.It is fair to say that the dominant view on this topic is that inequality is the outcome of a constant battle between convergence and "luck" (Gary Becker and Nigel Tomes, 1979).Current asset inequalities may echo into the future, but their natural tendency is to die out (owing to a convex investment technology).Disparities are only sustained through ongoing stochastic shocks (see also David Champernowne, 1953;Glenn Loury, 1981).A second approach emphasizes that initial conditions determine final outcomes, owing principally to a nonconvex investment technology (see e.g.

Measuring Market Inefficiencies in California's Restructured Wholesale Electricity Market

American Economic Review 2002 92(5), 1376-1405 open access
We present a method for decomposing wholesale electricity payments into production costs, inframarginal competitive rents, and payments resulting from the exercise of market power. Using data from June 1998 to October 2000 in California, we find significant departures from competitive pricing during the high-demand summer months and near-competitive pricing during the lower-demand months of the first two years. In summer 2000, wholesale electricity expenditures were $8.98 billion up from $2.04 billion in summer 1999. We find that 21 percent of this increase was due to production costs, 20 percent to competitive rents, and 59 percent to market power.

The Fed and the New Economy

American Economic Review 2002 92(2), 108-114 open access
This paper seeks to understand the behavior of Greenspan's Federal Reserve in the late 1990s. Some authors suggest that the Fed followed a simple "Taylor rule," while others argue that it deviated from such a rule because it recognized that the "New Economy" permitted an easing of policy. We find that a Taylor rule based on inflation and unemployment does break down in the late 1990s. However, the Fed's behavior appears stable once one accounts for the falling NAIRU of the period. A rule based on inflation and the deviation of unemployment from the NAIRU captures the Fed's behavior through the entire period from 1987 to 2000.

Do Corrupt Governments Receive Less Foreign Aid?

American Economic Review 2002 92(4), 1126-1137 open access
Critics of foreign aid programs argue that these funds often support corrupt governments and inefficient bureaucracies. Supporters argue that foreign aid can be used to reward good governments. This paper documents that there is no evidence that less corrupt governments receive more foreign aid. On the contrary, according to some measures of corruption, more corrupt governments receive more aid. Also, we could not find any evidence that an increase in foreign aid reduces corruption.

When Do Research Consortia Work Well and Why? Evidence from Japanese Panel Data

American Economic Review 2002 92(1), 143-159 open access
We examine the impact of a large number of Japanese government-sponsored research consortia on the research productivity of participating firms by measuring their patenting in the targeted technologies before, during, and after participation. Consistent with the predictions of the theoretical literature on research consortia, we find consortium outcomes are positively associated with the level of potential R&D spillovers within the consortium and (weakly) negatively associated with the degree of product market competition among consortium members. Furthermore, our evidence suggests that consortia are most effective when they focus on basic research.
