If firms purchase capital up to the point where there is no further marginal benefit, and the firms' securities are equal in value to the capital, then the market value of securities measures the quantity of capital. I explore the implications of this hypothesis using data from U.S. non-farm,...

Changes in government spending often lead to significant shifts in demand across sectors. This paper analyzes the effects of sector-specific changes in government spending in a two-sector dynamic general equilibrium model in which the reallocation of capital across sectors is costly. The...

We build a model of firm-level innovation, productivity growth and reallocation featuring endogenous entry and exit. A new and central economic force is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model...

This paper examines the stock market's valuation of a firm's innovative activity. We estimate the market's relative valuation of firms' tangible and intangible assets, focusing on knowledge capital in the form of accumulated quot;stocksquot; of Ramp;D and patents. We tried to improve upon our...

We study the resource allocation decisions of U.S. multinational corporations (MNCs). We examine how established MNCs grow across countries and how firm-specific resources and host country financial-market development influence MNC growth. We find evidence of intra-firm trade-offs to growth in...

We describe the broad range of uncertainties faced by the developers of medical technologies. Empirically, we estimate the asset market incidence of two realizations of uncertainties we classify as within-market policy risks. The events we analyze concern the intellectual property of Myriad...

The purpose of this paper is to present and estimate a model which allows one to use the recently computerized U.S. Patent Office's data base to identify when and where changes in inventive output have occurred. The model assumes a firm which chooses a research strategy to maximize the expected...

This paper provides novel empirical evidence on the private value of patents and Ramp;D in European firms during the period 1991-2004. We explore the relationship between firm's stock market value, patents, and quot;qualityquot;-weighted patents issued by the European Patent Office (EPO) and the...

Several studies based on US and UK data have used market value as an indicator of the firm''s expected R&D performance. However, there exist no investigations for the continental countries in the European Union, partly because the analysis is complicated by data availability problems. In this...
