This article examines how the scientific specialization of universities impacts new firm creation across industries at the local level. In accordance with the Pavitt-Miozzo-Soete taxonomy, we consider eight industry categories, which reflect the characteristics of firms’ innovation patterns and, ultimately, the knowledge inputs that firms require. Using data on new firm creation in Italian provinces (i.e., at the NUTS3 level), we estimate negative binomial regression models separately for each industry category to relate new firm creation to the scientific specialization in basic sciences, applied sciences and engineering, and social sciences and humanities of neighboring universities. We find that universities specialized in applied sciences and engineering have a broad positive effect on new firm creation in a given province, this effect being especially strong in service industries. Conversely, the positive effect of university specialization in basic sciences is confined to new firm creation in science-based manufacturing industries, even if this effect is of large magnitude. Universities specialized in social sciences and humanities have no effect on new firm creation at the local level whatever industry category is considered. 相似文献

Risk assessment has struggled to reconcile public views and opinion with the results of science-based objective assessment. In this paper, we attempt to tease apart subjective and objective considerations that risk management decisions entail. Through the use of examples from the New Zealand Environmental Risk Management Authority, we argue that risk managers need to use quantitative tools in order to develop an objective understanding of the biophysical outcomes of an activity. Decision-making should then enter a phase where democratic methods are used to allow people to weigh these physical outcomes subjectively. We believe allowing subjective democratic decisions, based on objective reality, will help enable risk management to bridge gaps between practitioners and the public. 相似文献

We consider a Constant Elasticity of Variance (CEV) model for the asset price of a defaultable asset showing the so-called leverage effect (high volatility when the asset price is low). We show that a VaR constraint re-evaluated over time induces an agent more risk averse than a logarithmic utility to take more risk than in the unconstrained setting. 相似文献

The financial crisis has affected the landscape of the banking sector around the world. We use a sample of transactions carried out by European acquirers in 2007–2010 to study the acquirer’s stock price market reaction to both announcements and completions of acquisitions. At the aggregate level, we find that there are no significant abnormal returns around the announcement of an acquisition while there are positive abnormal returns at completions. We study the cross-sectional determinants of abnormal returns and find that announcement returns are mainly explained by the acquirer bank characteristics, while completion returns mainly depend on opacity of the target and on the drop in idiosyncratic volatility associated with a reduction of uncertainty. 相似文献

This study examines the value relevance and timeliness of write-downs reported by North American and European banks during the financial crisis of 2007–2009. Our study extends Vyas (2011), considering the association between write-downs and stock returns to evaluate the performance of fair value standards during the crisis. Specifically, we investigate claims that strict enforcements of standards resulted in write-downs that were excessive or unnecessary due to temporary market price distortions, or conversely, that standards were flexible enough to allow managers to engage in earnings or capital management. Our empirical results show that both fair-value and aggregate write-downs are associated dollar-for-dollar with contemporaneous security returns, suggesting that, on average, write-downs were timely throughout the financial crisis. 相似文献

This paper describes the market for borrowing corporate bonds using a comprehensive data set from a major lender. The cost of borrowing corporate bonds is comparable to the cost of borrowing stock, between 10 and 20 basis points, and both have fallen over time. Factors that influence borrowing costs are loan size, percentage of inventory lent, rating, and borrower identity. There is no evidence that bond short sellers have private information. Bonds with Credit Default Swaps (CDS) contracts are more actively lent than those without. Finally, the 2007 Credit Crunch does not affect average borrowing costs or loan volume, but does increase borrowing cost variance. 相似文献

I examine the introduction of an online shopping service by a large supermarket chain also operating a network of brick‐and‐mortar stores. The establishment of the Internet channel led to a 13 percent increase in overall revenues, with limited cannibalization of traditional sales. I study the mechanisms underlying this result, focusing on two areas. First, I demonstrate the importance of the reduction of customers' travel costs in the attraction of new business. Second, I provide some evidence that revenues increase more in markets where the chain faces more competitors, suggesting that the online channel can help divert business from rival supermarkets. 相似文献

This paper investigates the role of public knowledge partnerships in EU-funded framework programmes (FP) on knowledge creation across a sample of European countries. Different from previous studies, we investigate whether the impact of participation in FP on new knowledge (patents) differs across private companies, universities and public research centres. We find that, while all institutional sectors benefit from joint projects, the main benefits (in terms of patenting activity) go to universities and public research centres, while private companies benefit less. We also find evidence of important complementarities between participation in international research projects and internal innovation drivers (researchers), thus highlighting the crucial role of domestic absorptive capacity for fully benefiting from international cooperation in R&D projects. 相似文献

ABSTRACTSince 1994 the state has instituted active labour market policies to redress the apartheid skills legacy. The skills planning challenge continues to be how to coordinate efforts for the provision of the right skills to support inclusive economic growth, ensuring an alignment is achieved between what is required in the labour market and the supply from the education and training system. This article traces the South African journey of skills planning from late apartheid until the current time period in 2014 through a historical analysis of the political economy. The analysis reflects on the relationship between state formation in South Africa and the role of the state in directing skills development, and in the more recent period how skills planning responds to both the demands of the economy and ameliorating the historical legacies of education and skills exclusion. 相似文献
