Empirical studies of the external effects of R&D suggest that both geographic and technological distance attenuate inter-firm spillovers from innovative activity. The results presented here indicate that the tendency for R&D spillovers to localize economic activity is conditional on the...

We present an integrated summary of the various factors that contributed to shortages of electrical power in California in 2000. Several necessary conditions for the crisis are identified. We conclude that a sufficient remedy may be defined by policies that mitigate the limited incentives to...

We consider an environment in which participants make payments over a network and can invest in a technology that reduces the marginal cost of using the network. A network effect results in multiple equilibria; either all agents invest and usage of the network is high or no agents invest and...

Evidence is presented which suggest that an important measure of the apparent geographic localization of R&D spillovers may be an artifact of industrial agglomeration. A production function framework is used to examine the role of geographic and technological proximity for inter-firm spillovers...

Innovation enhances economic performance. High rates of innovation are associated with high rates of productivity growth, and faster productivity growth leads to higher real wages and improvements in standards of living. Consequently, many local policymakers are eager to encourage higher rates...

Does auditor independence increase the quality of financial disclosures, and is regulation necessary to realize such improvements? Conventional wisdom answers "yes!," but lacks support from scholarly studies. We thus investigate whether auditor independence affects earnings quality in ways that...

By choosing to locate in a particular place, firms create employment opportunities for workers living there. And the wages they pay increase demand for local goods and services, creating additional job opportunities and further increasing the tax base. Consequently, state and local governments...

We examine incentives for network-specific investment and the implications for network governance. We model an environment in which participants that make payments over a network can invest in a technology that reduces the marginal cost of using the network. A network effect results in multiple...
