This paper has two main objectives. First, it estimates the impact of related and unrelated variety of European regions’ knowledge structure on their patenting activity. Second, it looks at the role of technological relatedness and extra-local knowledge acquisitions for local innovative activity. Specifically, it assesses how external technological relatedness affects regional innovation perfor...

A spatial dynamic panel data approach is adopted to study regional growth convergence in the U.S. economy. In the neoclassical growth model, regions and countries are assumed to be independent from each other, which may not be valid in the real world. We introduce technological spillovers into the neoclassical framework, showing that the convergence rate is higher and there is spatial interacti...

This paper studies whether labor scarcity encourages technological advances, i.e., technology adoption or innovation, for example, as claimed by Habakkuk in the context of 19th-century United States. I de…ne technology as strongly labor saving if technological advances reduce the marginal product of labor and as strongly labor complementary if they increase it. I show that labor scarcity encour...

The sources of aggregate productivity growth are explored using detailed data for four-digit U.S. manufacturing industries during 1958-96 and a decomposition formula which allows to quantify the contribution of structural change. Labor productivity as well as total factor productivity are considered and the aggregation is performed with either value-added or employment shares. It is shown that ...

Studies have found the impact of foreign direct investments (FDI) on productivity growth to be firm-industry-host economy specific. However, the impact of FDI may differ with the existing market conditions in the economy and also with respect to the source of the FDI. The paper examines the impact of FDI on productivity growth of the Indian industry in the period of low market demand conditions...

How does technological progress occur? Is the nature of innovation stable over time? We shed new light on these questions through a mixture of empirics and theory. We begin with an empirical analysis of patents granted by the United States Patent and Trademark Offi ce. This analysis reveals several striking facts that emphasize the increasing importance of novel combinations of technologies for...

We analyze the implications of entrepreneurial spawning for a variety of firm characteristics such as size, focus, profitability, and innovativeness. We examine the dynamics of spawning over time. Our model accounts for much of the empirical evidence relating to the relation between spawning and firm characteristics. Firms that have higher patent quality spawn more, as do firms that have higher...

We propose a strategy to identify the complementarity or substitutability among technology bundles. Differences between the observed distribution of technology choices can be subjected to statistical tests. Combinations of technologies that occur with greater frequency than would occur under independence are complementary technologies. Combinations that occur with less frequency are substitute ...

We evaluate whether hospital adoption of electronic medical records (EMRs) leads to increases in billing where financial gains are large or where hassle costs of complete coding are low. The 2007 Medicare payment reform varied both financial incentives and hassle costs of coding. We find no significant impact of financial incentives on billing levels, inconsistent with bill inflation. However, ...
