This paper explores insights about marginal airport costs that can be gained by analysing labour inputs and their variability. Based on hourly cost and traffic data for the airport of Helsinki, a multivariate time series approach is used incorporating correlated error terms to account for random shocks such as delays. We found for most airport services a linear relationship between labour input and aircraft movements, except for producing passenger services for international departing flights where a cubic cost relationship was estimated. The findings are comparable with earlier studies for US airports.  相似文献

Using project data from a random sample of Phase II research awards from the National Institutes of Health SBIR program, we estimate the relative probability that woman-owned firms are able to attract private investments to fund the transition of the technology developed under the sponsorship of the SBIR program to an innovation to enter the market. We find that women-owned firms are as much as 16% points less likely to attract private investment dollars compared to male-owned firms, factors excluding the size of the SBIR award held constant. Women-owned firms that received larger awards performed substantially better. Although the SBIR program has a legislated directive to increase the participation of woman-owned firms in the program, our findings suggest that it might not be sufficient to overcome market perceptions about the profitability of such investments actually bringing a developed technology to market.  相似文献

This paper discusses the appropriateness of literature-based innovation output indicators in the evaluation arena, and it sets forth criteria against which to judge such appropriateness.This paper was motivated by discussions with Zoltan Acs regarding new concepts in innovation output measurement and the implications of those concepts for small firms.  相似文献

It is well known that government R&D and private R&D have a complementary relationship. However, no previous study has provided an explanation for why that complementary relationship exists. This paper argues that infratechnology is the critical link between governmental and private R&D and that the observed complementarity is the result of technical complementarity at the production level between funding, infratechnology, and knowledge sharing. A theoritical framework based on this argument is developed and examined empirically for supporting evidence. Evidence of technical complementary is found as well as evidence that governmental R&D stimulates the sharing of knowledge.  相似文献

Small-sized firms are typically more entrepreneurial and engage in more innovation and risk-taking behavior. For that reason they are considered the engines of future economic growth. One policy for stimulating such activity is to provide government contracts for small firms. However, such contracts as typically written result in increased risk-averse behavior on the part of small firms out of a desire by government officials to shift the risk to the firms. This, in turn results in a reduced level of innovative and entrepreneurial activity. To eliminate the disincentive to engage in innovation and entrepreneurial activity, government needs to bear the risk associated with such contracts. One possible solution, given the natural risk aversion of elected officials, is to engage in a portfolio approach to small firm contracts by which the government can diversify away some of the risk.  相似文献

US- owned firms account for more than 60% of worldwide computer software sales, and US capability in software tachnology is widely viewed as well ahead of that in other countries. However, the US lead cannot be expected to last. Nor are policies yet in place intended to protect exisitng advantages. Japanese firms have demonstrated their capabilities in hardware. Japanese firms have demonstrated their capabilities in hardware. Japanses exxecutives know they must develop better software in order (1) to use their own computer systems to best advantge, and (2) to sell more hardware in export markets. The next several devades will see a gradual slippage in the US position, particularly as foreign software suppliers move away from custom programming an realted services, their present focuse. A narrowing gap between US and foreign industries could prefigure a competitive challenge in software, development not unlike earlier challenges in microelectronics. Better software,. in addition, will have impacts elsewhere.In Japan's case, for example, improvements in softwarte should lead to productivity enhancements throughout the economy, improving Japan's ability to tmpete internationally.  相似文献

The premise of this paper is that a basis for firms receiving Small Business Innovation Research (SBIR) research awards to develop commercializable technologies is not only their proposed creative ideas but also their endowment of attendant knowledge necessary to develop the technology being proposed. Based on this premise, we propose that those firms that have higher growth rates attributable to their SBIR awards are also those firms that are more creative and have more knowledge endowments. Empirically, we quantify a firms creativity and its sources of research knowledge in terms of its past experiences, and we find that firms with more technical experience and sector experience are those that have realized higher growth rates from their SBIR-funded research.

All federal programs are accountable for their use of public funds. This paper presents conservative estimates of the net social benefits associated with the Baldrige National Quality Award Program, established within the National Institute of Standards and Technology in 1987. On the basis of survey data from members of the American Society for Quality, we estimate cost savings benefits to members, extrapolate those benefits to the economy as a whole, and compare the benefits to the social costs associated with the Program. Our estimation method implies that the ratio of economy-wide benefits to social costs probably exceeds 207:1, supporting the hypothesis that the public investments in quality-standards infrastructure are worthwhile.  相似文献
