We explore the role of interfirm alliances as a mechanism for sharing technological knowledge. We argue that knowledge flows between alliance partners will be greater than flows between pairs of nonallied firms, and less than flows between units within single firms. Using patent citations as a proxy for knowledge flows, we find results that are consistent with these expectations. We then explore how firm characteristics affect knowledge flows within alliances and find positive effects due to technological, geographic, and business similarities between partners. We use alliance data from MERIT, patent data from the USPTO, and firm data from Compustat. 相似文献

Much research has investigated the differences between option implied volatilities and econometric model-based forecasts. Implied volatility is a market determined forecast, in contrast to model-based forecasts that employ some degree of smoothing of past volatility to generate forecasts. Implied volatility has the potential to reflect information that a model-based forecast could not. This paper considers two issues relating to the informational content of the S&P 500 VIX implied volatility index. First, whether it subsumes information on how historical jump activity contributed to the price volatility, followed by whether the VIX reflects any incremental information pertaining to future jump activity relative to model-based forecasts. It is found that the VIX index both subsumes information relating to past jump contributions to total volatility and reflects incremental information pertaining to future jump activity. This issue has not been examined previously and expands our understanding of how option markets form their volatility forecasts. 相似文献

An attitudinal and behavioral change program was developed and implemented in a service operations function. Changes were (1) stabilizing operations management (reducing turnover) and (2) improving attitudes and behaviors of employees with strong union affiliations in a common carrier trucking terminal when compared to similar employees in a control terminal undergoing no planned change. Management turnover was reduced. Other results from the eighteen-month longitudinal study indicated that employee attitudes in both groups remained negative toward work, management, and the company throughout the study period. Behaviors relating to attitudes — particularly turnover, absenteeism, and accident rates—improved at the experimental terminal, even though expressed attitudes remained negative. Operating efficiencies and profitability improved at the experimental terminal. It was found that these employees, pick-up and delivery drivers, retain positive attitudes toward customers and customers the same toward them, in spite of the drivers' negative attitudes toward the company. The operative service employee appeared to discriminate between attitudes toward the company and the customer; the drivers' negative attiudes toward most everything (except the customer) not affecting the customer's perceptions of the driver or the company. 相似文献

The material in this volume is the result of a call for papersto the participants of the "Conference on Analysis of High-FrequencyFinancial Data and Market Microstructure" held in December 2003in Taipei, Taiwan. Jeffrey Russell and Ruey Tsay have actedas guest editors for this special issue, together with the editorsRené Garcia and Eric Renault. The availability of high-frequency data has spawned considerableliterature on volatility measurement and forecasting. The materialis mathematically delicate and perhaps "PractitionersCorner" would be well advised to let the dust settle a bit tosee what emerges at the end of the day. On the other hand, thepractically minded may well be served by a good road map ofthe issues. So with only mild apology do we take up the cartographyof some difficult terrain. To fix ideas, let S(t) denote the price process of a . . . [Full Text of this Article] 相似文献

Some employers have begun to undertake a variety of initiatives, collectively termed value-based purchasing (VBP), which aim at factoring quality into the purchasing decision-making process when negotiating costs with providers and insurers. There is evidence that the VBP movement has begun gaining momentum; yet it is unclear whether employers are firmly committed to VBP principles. By surveying a national sample of employers, this study investigates the extent to which employers are currently engaged in VBP activities and also increases our understanding of barriers hampering the broader implementation of these activities. 相似文献

Using cross-industry survey data, I examine how the determinants of the pace of work affect the probability of using piece rates. Internal determinants raise the likelihood of piece rates, while response to external needs lowers the probability. 相似文献
