Although university patenting has increased dramatically over the past three decades, debates persist regarding the broad economic implications of the phenomenon. This article examines the social welfare implications of university patenting in a model of R&D competition in which firms develop innovations on the basis of the disclosure of a university invention. When such disclosure does not preempt the patenting of downstream innovations, university patenting enhances social welfare only if a regime of open access to university inventions is characterized by excessive aggregate R&D from the viewpoint of social welfare. When the university invention disclosure preempts patenting on firms’ innovations, the nature of the open access equilibrium in the R&D market depends on the threat of imitation ex post. Only when the threat of imitation is sufficiently strong firms will not invest in downstream R&D in the open access regime. In this case, university patenting promotes R&D investment and increases social welfare. 相似文献

This paper investigates the presence of liquidity premia in the relative pricing of assets traded on the Spanish government securities market. First, a classification of bonds into four different categories based on their degree of liquidity is proposed. Second, liquidity premia are estimated introducing liquidity parameters in the estimation of the zero-coupon yield curve. Results suggest the existence of a liquidity premium for post-benchmark bonds (both strippable and non-strippable). The size of this premium is relatively small. In the case of pre-benchmark bonds, the lack of liquidity does not seem to be priced. It is also shown that these pricing discrepancies are robust to the impact of taxes on bonds. 相似文献

The management of environmental programmes often involves several stakeholders with diverse, and often conflicting, concerns. This paper proposes a methodology for the assessment of stakeholder preferences regarding a number of objectives of environmental restoration activities, such as the minimization of costs and of the impact on human health and safety. This methodology is based on an analytic/deliberative process that starts with pairwise comparisons of these objectives using questionnaires that the stakeholders complete. This input is used to produce a first set of relative weights using the Analytic Hierarchy Process (the analytic part). This set, as well as possible inconsistencies of the stakeholder assessments, is discussed with the stakeholders to correct inconsistencies and revise the weights (the deliberative part). The stakeholders always have the final word regarding the relative weights. Insights gained from a case study are also presented. The feedback from the stakeholders participating in this exercise was positive. 相似文献

Shadow economy and unemployment rate in USA: is there a structural relationship? An empirical analysis 总被引:1,自引:0,他引:1
This article aims to estimate the size of the US shadow economy (SE) using a structural equation approach and to evaluate if a structural relationship exists between the SE and the unemployment rate (UR) in the United States. The size of the SE is estimated to be decreasing over the last two decades. We corroborate the existence of a structural relationship between the SE and the UR by using a simple theoretical model. Furthermore, we extend the Okun's law to estimate the structural relationship between growth rate of official GDP, SE and UR. Our results indicate a significant positive relationship between the SE and the UR. 相似文献

ABSTRACT This article analyzes what influences a firm's choice of strategy—why some firms stick to defensive strategies while others rely on offensive ones. With this in mind a survey was conducted on mineral sector companies associated with the Brazilian Mining Institute. The results show that the majority of companies use an offensive strategy and that some companies use more than one strategy at the same time. That is, they possess a corporate strategy and a sustainability strategy. 相似文献

Value for money (VfM) is a key parameter for the public sector in the choice between a public–private partnership (PPP) and traditional procurement, especially for healthcare infrastructure. This paper investigates the differences in what VfM means to the public and private sectors. 相似文献

This article presents a structured process to make facility location decisions based on regional industrial capabilities. It presents a framework for collecting business intelligence on major cities of the region of interest. In the next step, the collected business intelligence is incorporated into a quantitative decision analysis model for facility location. While the proposed framework is generic and builds on the existing international business and supply chain management literature, the article mainly focuses on the facility location problem of a distribution firm that is not well represented in the literature. Two cases—one each for new and established distributors who are trying to sell to the Mexican market—are presented in the article. 相似文献

This paper uses a broad multi-country dataset to describe the main stylized facts about export performance in the last four decades. First, transition probability matrices are computed to look at changes in the position of countries at the world distribution of the export to GDP ratio. It finds that transitions toward high export ratios have been mainly experienced by Asian countries, but also that some reformers, like Mexico and Chile, have been able to improve their position relative to other studied economies. African countries mainly sunk to the bottom part of the world distribution, although they constitute only half of the economies with relatively bad export performance. In the consideration of the structural factors that may play an important role for long-run transitions, the results suggest that more open economies and those with better institutions are more likely to move to high export ratios in the long-run. Second, the within-country experiences are analyzed for identifying episodes of export transitions. Using an event study methodology, a very weak association is found between export transitions and investment rate. In contrast, the results suggest that transitions are potentially driven by improvements in financial development. Finally, favorable terms of trade, increments in productivity, and reductions in exchange rate distortions are not found to be a catalyst for export transitions. 相似文献

This paper reports the study of some factors that influence the control intensity exerted by franchisors on the service quality provided by the franchised units of their networks and what interdependencies exist between the different mechanisms that can be used to monitor service quality. On the one hand, three control mechanisms of conformance quality are considered, namely audits, mystery shoppers, and mandatory purchase of inputs and products. On the other hand, polls are used to monitor perceived quality by customers. There are two main findings. First, control intensity is greater in those industries in which customers tend to be non-repetitive. Second, four complementary relationships are found between control mechanisms: between audits and mystery shoppers, between audits and polls, between mandatory purchase of inputs or products and mystery shoppers, and between mandatory purchase of inputs or products and polls. 相似文献

This article investigates agricultural price transmission during price bubbles. The empirical approach concerns the horizontal transmission of cereal prices both across different market places and across different commodities. The trade policy intervention put forward to mitigate the impact of price exuberance is considered. The analysis is performed using Italian and international weekly spot (cash) price data over years 2006–2010, a period of generalized turbulence of agricultural markets. Firstly, the properties of price time series are explored; then, interdependence across prices is specified and estimated by adopting appropriate cointegration techniques. Results suggest that the bubble had only a slight impact on the price spread and the temporary trade‐policy measure, when effective, has limited this impact. 相似文献
