This paper evaluates a fellowship scheme aiming to overcome attitudinal and operational barriers towards university technology transfer. We propose barriers exist because of the focus of many academics exclusively within a peer review research network. We explore the case of the Medici Fellowship programme that was implemented in biomedical departments across five universities located in the midlands of England. Our evidence suggests that such fellowship programmes, through the retraining of academics, may have a positive impact on the commercialisation of research. In particular, the fellows, through the enhancement of their social and human capital, are able to act as agents of attitudinal change in their host departments and are seen to build bridges into external business networks that can provide early stage funding, market and legal information and help identify potential customers for nascent academic entrepreneurs. 相似文献

In this paper we examine the tests of the new classical rational expectations and structural neutrality hypotheses undertaken by Leiderman (1980) using a model of money growth and unemployment for the United States developed by Barro (1977). Employing the data used in the studies by Barro and Leiderman we are able to construct an alternative model of money growth and unemployment against which the Barro-Leiderman model is rejected along with the joint hypothesis of rational expectations and structural neutrality. 相似文献

This paper investigates the return performance of publicly traded real estate companies. The analysis spans the 1984–1999 time period and includes return data on over 600 companies in 28 countries. The return data reveal a substantial amount of variation in mean real estate returns and standard deviations across countries. Moreover, standard Treynor ratios, which scale country excess returns by the estimated beta on the world wealth portfolio, also reveal substantial variation across countries in excess real estate returns per unit of systematic risk. However, when we estimate Jensens alphas using both single and multifactor specifications, we detect little evidence of abnormal, risk-adjusted returns at the country level. We do, however, find evidence of a strong world-wide factor in international real estate returns. Furthermore, even after controlling for the effects of world-wide systematic risk, an orthogonalized country-specific factor is highly significant. This suggests that real estate securities may provide international diversification opportunities. 相似文献

A review on cost-effectiveness analysis of agri-environmental measures related to the EU WFD: Key issues, methods, and applications 总被引:1,自引:0,他引:1
The European Water Framework Directive (WFD) explicitly integrates economics into water management and water policy in Europe. Specifically, Article 11 and Annex III of the Directive call for a cost-effectiveness analysis (CEA) of alternative mitigation measures as a requirement in formulating Programme of Measures (PoMs) to achieve ‘good ecological status’ for all waters in Europe. As agriculture is supposed to be the major contributor to diffuse water pollution, CEA of agri-environmental measures has been given paramount importance in establishing the PoMs. This paper summarises the status, significance, and methodological limitations of WFD-related CEA studies in Europe. Cases from the United Kingdom, countries surrounding the Baltic Sea and central and southern Europe were included in the review. Review results indicate that most WFD-related CEA studies: (1) were based on models of ‘representative’ farms without capturing the variability among real-world farms; (2) concentrate on a single ecological effect of measures or are based on cost estimates of the sectors directly involved in the pollutant-reduction programme (i.e., co-benefits, trade-offs, and external costs were not examined); and (3) did not incorporate uncertainties in both cost and effectiveness estimates. Based on the review results, the paper suggests policy implications and recommendations for future research in the field. 相似文献

Recent work considers whether information is simultaneously reflected in both option and equity markets. We provide new evidence
supporting Black’s (Financ. Anal. J. 31:36–72, 1975) conjecture that information is first revealed in option markets. Specifically, changes in call and put open-interest levels
have predictive power for future equity returns. Large increases in call open interest are followed by significantly increased
equity returns. Put open-interest increases precede weaker future returns, but the relationship is considerably less pronounced
in the presence of certain controls. The recent change in the call-to-put open-interest ratio has predictive power as to equity
returns over the following week, even after controlling for numerous factors. 相似文献

International markets are increasingly signaling demand for quality-differentiated coffee, which the Colombian Coffee Growers Federation (FNC) proposed to exploit to identify those regional coffees that would fulfill the requirements to be classified as denomination of origin. The objective of this study was to develop and implement a sound, robust and repeatable approach with and for the FNC to identify regional causal relationships between coffee quality and environmental characteristics as bases for labels of denomination of origin. Environmental differences between coffee-growing areas in the departments of Cauca and Nariño were statistically significant for several characteristics, including the number of dry months, annual precipitation and diurnal temperature range. The dominant varieties (Caturra and Colombia) did not show major differences in quality attributes, and were pooled for the analyses with the environmental data. There are significant differences in biochemical and sensorial product characteristics between the two departments. The spatial patterns in product characteristics exhibit a non-random, regionally-changing structure that is related to those in the environmental data. The generated results provided ample evidence to support the application for regionally-based denominations of origin. Recommendations were derived to help mainstreaming the developed approach and thereby facilitate policy decisions for its use in other geographies and with other crops. Furthermore, the importance of systematic interdisciplinary institutional collaboration for large-scale denomination of origin projects was corroborated for food policy dialogue and decision making. It seems plausible that producers of high-quality products within other commodities are likely to follow the FNC in seeking denomination of origin for their goods. The presented approach is crucial to facilitate policy. 相似文献

Although most managers publicly acknowledge the need to explore new businesses and markets, the claims of established businesses on company resources almost always come first, especially when times are hard. When top teams allow the tension between core and speculative units to play out at lower levels of management, innovation loses out. At best, leaders of core business units dismiss innovation initiatives as irrelevancies. At worst, they see the new businesses as threats to the firm's core identity and values. Many CEOs take a backseat in debates over resources, ceding much of their power to middle managers, and the company ends up as a collection of feudal baronies. This is a recipe for long-term failure, say the authors. Their research of 12 top management teams at major companies suggests that firms thrive only when senior teams lead ambidextrously--when they foster a state of constant creative conflict between the old and the new. Successful CEOs first develop a broad, forward-looking strategic aspiration that sets ambitious targets both for innovation and core business growth. They then hold the tension between innovation unit demands and core business demands at the very top of the organization. And finally they embrace inconsistency, allowing themselves the latitude to pursue multiple and often conflicting agendas. 相似文献

We investigate conflicts between wildlife conservation and recreational use that can occur at open-access sites when visitors dislike crowding. A theoretical model is proposed which determines the spatial distributions of visitors to a beach, given their willingness to walk to avoid crowding and the configuration of beach access points. This model is estimated for three sections of coastline in eastern England using data from aerial video photography. Visitor density is strongly and negatively correlated with distance from access points. Willingness to walk has a highly skewed population distribution. We discuss the implications of these findings for the management of conflicts between conservation and recreation at open-access sites. 相似文献

In many markets, buyers, sellers, and their agents have differential information about the quality of heterogeneous assets. We study negotiated transaction prices in the commercial real estate market, which is characterized by heterogeneous assets, illiquidity, and highly segmented local markets, all of which increase the importance of asymmetric information in negotiated pricing outcomes. Using 114,588 industrial, multi-family and office sale transactions that occurred during 1997–2011, we document that distant commercial real estate buyers pay, on average, premiums of 4 % to 15 % relative to local buyers, controlling for individual property characteristics as well as time fixed-effects. We also examine the extent to which the sources of these observed premiums are a product of higher search costs/information asymmetry problems associated with distance (search cost channel) or a result of reference-dependence preference/anchoring based on the price levels in the investors’ local market (behavioral biases channel). Our results suggest the observed price premiums are explained by distant investors who face higher search costs and are at an information disadvantage compared to investors located in closer proximity to the property. In contrast, anchoring plays a more muted role in explaining observed premiums. The use of an intermediary (broker) increases, on average, the acquisition prices of buyers and decreases the disposition prices of sellers by 3 % to 8 %. This result is consistent with the incentive real estate agents have to convince sellers to dispose of their properties too quickly and to convince buyers to search less and therefore pay higher prices. 相似文献
