Intangibles: what put the new in the new economy?
Generating new products requires corporations to spend very large sums of money. These expenditures often lead to the development of intangible assets, such as patents and copyrights, that can add considerably to a company's coffers and stock market value. However, in general, our accounting conventions do not recognize these expenditures as investments--a holdover from the days when these types of investments were a negligible portion of total investment. Leonard Nakamura argues that these conventions cause profits and savings to be understated and that correcting them makes U.S. economic ...
Innovating firms and aggregate innovation
We develop a parsimonious model of innovating firms rich enough to confront firm-level evidence. It captures the dynamic behavior of individual heterogeneous firms, describes the evolution of an industry with simultaneous entry and exit, and delivers a general equilibrium model of technological change. While unifying the theoretical analysis of firms, industries, and the aggregate economy, the model yields insights into empirical work on innovating firms. It accounts for the persistence over time of firms? R&D investment, the concentration of R&D among incumbent firms, and the link between ...
Knowledge diffusion through employee mobility
In high-tech industries, one important method of diffusion is through employee mobility: many of the entering firms are started by employees from incumbent firms using some of their former employers? technological know-how. This paper explores the effect of incorporating this mechanism in a general industry framework by allowing employees to imitate their employers? know-how. The equilibrium is Pareto optimal since the employees ?pay? for the possibility of learning their employers? know-how. The model?s implications are consistent with data from the rigid disk drive industry. These ...

R&D spending and cyclical fluctuations: putting the "technology" in technology shocks
We examine the dynamic properties of an endogenous growth model with an explicit R&D sector in order to evaluate its ability to propagate temporary disturbances into persistent fluctuations in macroeconomic variables. We demonstrate that a large proportion of the variability and persistence of measured Solow residuals can be thought of as reflecting the endogenous accumulation and adaptation of technical knowledge rather than simply exogenous processes. By explicitly modeling R&D, we use a framework in which it is possible to explicitly consider the role of technology in "technology shocks."
Academic rankings with RePEc
This document describes the data collection and use of data for the computation of rankings within RePEc (Research Papers in Economics). This encompasses the determination of impact factors for journals and working paper series, as well as the ranking of authors, institutions, and geographic regions. The various ranking methods are also compared, using a snapshot of the data.
The rise and fall of a policy rule: monetarism at the St. Louis Fed, 1968-1986
From the 1960s to the 1980s, the Federal Reserve Bank of St. Louis played an important and highly visible role in the development and advocacy of stabilization policy based on the targeting of monetary aggregates. Research conducted at the St. Louis Bank extended earlier monetarist analysis that had focused on the role of money in explaining economic activity in the long run. Their success in finding apparently robust, stable relationships in both long- and short-run data led monetarists to apply long-run propositions to short-run policy questions, effectively competing with alternative views ...
On the timing of innovation in stochastic Schumpeterian growth models
Recent work has revived the Schumpeterian hypothesis that recessions facilitate innovation and growth. But a major source of productivity growth, research and development, is actually procyclical. This paper argues that while it is optimal to concentrate growth enhancing activities in downturns, dynamic spillovers inherent to the R&D process lead private agents to concentrate too much of their R&D activity in booms, precisely when its social cost is highest. Thus, while previous literature has argued recessions promote growth and intertemporal substitution is a desirable consequence of ...
