This paper re-examines the empirical evidence on the degree of spatial spillover between university research and high technology innovations. The familiar Griliches–Jaffe knowledge production function is estimated at both the state and the metropolitan statistical areas (MSA) level and extended with more precise measures of spatial spillover. Alternatives based on the gravity potential and covering indices are formulated for Jaffe's “geographical coincidence index” and found to provide strong evidence of local spillovers at the state level. At the MSA level, a distinction is made between research and development activities and university research in the MSA and in the surrounding counties. Evidence is found of local spatial externalities between university research and high technology innovative activity, both directly and indirectly via private research and development.  相似文献

ABSTRACT

While most consumers today feel concerned by environmental issues, the consumption of hot beverage in disposable cups remains very important. In this study, we use influence strategies related to social norms to reduce these behaviors and get consumers to consume their hot beverage in reusable cups. 14373 orders were analyzed and demonstrate that normative messages can be effective to change consumer behavior toward a more responsible choices.  相似文献

This article describes the open private pension plans offered in Brazil, which is one of the four pillars of the Brazilian retirement system. A framework is created to describe and analyze the impact of the transaction costs and tax advantages one can obtain from these financial products. This framework allows us to show and measure the advantages of these products versus other alternatives for long-term investment in the Brazilian financial market. It is shown that private plans are better than direct investment in funds in a high interest rate environment.  相似文献

More than a third of the EU budget is devoted to Cohesion Policy with the objective to foster economic and social cohesion in the European Union. Large-scale fiscal transfers are used to support investment in infrastructure, R&D and human capital. This paper provides a model-based assessment of the potential macroeconomic impact of these fiscal transfers using a DSGE model with semi-endogenous growth (Jones, 1995) and endogenous human capital accumulation. The simulations show the potential benefits of Structural Funds with significant output gains in the long run due to sizeable productivity improvements.  相似文献

Entrepreneurship,Agglomeration and Technological Change   总被引:4,自引:1,他引:4  
A growing body of literature suggests that variations across countries, in entrepreneurial activity and the spatial structure of economies could potentially be the source of different efficiencies in knowledge spillovers, and ultimately in economic growth. We develop an empirical model that endogenizes both entrepreneurial activity and agglomeration effects on knowledge spillovers within a Romerian framework. The model is tested using the GEM cross-national data to measure the level of entrepreneurship in each particular economy. We find that after controlling for the stock of knowledge and research and development expenditures, both entrepreneurial activity and agglomeration have a positive and statistically significant effect on technological change in the European Union.
