There is increasing awareness that university–industry collaboration provides an important knowledge transfer channel and, thus, is a powerful driver of innovation. Universities are increasingly being asked to play incisive roles in the process of regional economic development. This paper assesses the extent to which university–industry collaboration, expressed in terms of private funding for university consulting research activities, is affected by the geographic proximity of an academic institution to an Industrial District (ID). Although the economic literature insists on the positive effects of proximity for these collaborations, empirical work on Italian ID so far shows no particular effects. This paper provides new insights into the effects of academic proximity to ID on university–industry collaboration, by presenting robust evidence that proximity to districts promotes the establishment of collaboration agreements. This sheds new light on the need for targeted policies to support local productive systems. The empirical evidence is based on an analysis of qualitative information and an econometric analysis of financial data for the whole population of Italian university departments engaged in research in the Engineering and Physical Sciences.  相似文献

The paper tests different theories of how diversification by Venture Capital (VC) firms affects fund performance. The Financial Intermediation and the Resource-based Theory suggest that lower financial risk associated with diversification implies a lower return. However, the assumptions of these theories are questionable in the context of venture capital. We test their validity using data on VC portfolio diversification by industry and country using an original dataset of 649 VC funds originating in the United Kingdom over the period 1981–2000. Results show that higher diversification by industry does indeed lower VC fund success rates. Diversification by geographical region, on the contrary, increases returns.  相似文献

At the height of the COVID-19 related market stress in March 2020, six European countries implemented market-wide short selling bans. Based on a difference-in-difference approach using regulatory data, our estimation finds that the bans are associated with a deterioration in liquidity and trading volumes, and a decrease in volatility, without evidence of price impact. Remarkably, the negative impact persisted after the bans' lift. Liquidity deterioration appears stronger for liquid shares- large-cap, highly fragmented stocks, and stocks with listed derivatives. Sectoral effects are noticed for the stocks most affected by the market stress. Finally, no displacement effect was observed.  相似文献

Family firms represent a globally dominant form of organization, yet they confront a steep challenge of finding and managing competent leaders. Sometimes, these leaders cannot be found within the owning family. To date we know little about the governance contexts under which non‐family leaders thrive or founder. Guided by concepts from agency theory and behavioural agency theory, we examine the conditions of ownership and leadership that promote superior performance among non‐family CEOs of family firms. Our analysis of 893 Italian family firms demonstrates that these leaders outperform when they are monitored by multiple major family owners as opposed to a single owner; they also outperform when they are not required to share power with co‐CEOs who are family members, and who may be motivated by parochial family socioemotional priorities.  相似文献

Trade policy literature has for many years emphasized open policies positive impact on economic growth and development. While these results generally hold when measured on averages, empirical evidence suggests that trade liberalization is unlikely to produce beneficial results across all households. This study adds to the literature by providing an analysis of the distributive effects of tariff liberalization in Mexico. The paper examines the effect of tariff liberalization from the perspective of households both as consumers and factor owners allowing for imperfect domestic price transmission. The results indicate the overall positive effect of tariff liberalization masks significant differences in the distribution of gains both across income levels and across geographic regions. Richer households are found to have gained relatively more. Urban areas, as well as Mexican states closest to the United States border, are also found to be larger beneficiaries while southernmost states have been largely bypassed by the effects of tariff liberalization. Those results can be explained not only in relation to the different endowments of the households, but also by the diverse effects on local prices that has resulted from Mexican trade liberalization.  相似文献

A research agenda for improving national Ecological Footprint accounts   总被引:3,自引:0,他引:3  
Nation-level Ecological Footprint accounts are currently produced for more than 150 nations, with multiple calculations available for some nations. The data sets that result from these national assessments typically serve as the basis for Footprint calculations at smaller scales, including those for regions, cities, businesses, and individuals. Global Footprint Network's National Footprint Accounts, supported and used by more than 70 major organizations worldwide, contain the most widely used national accounting methodology today. The National Footprint Accounts calculations are undergoing continuous improvement as better data becomes available and new methodologies are developed. In this paper, a community of active Ecological Footprint practitioners and users propose key research priorities for improving national Ecological Footprint accounting. For each of the proposed improvements, we briefly review relevant literature, summarize the current state of debate, and suggest approaches for further development. The research agenda will serve as a reference for a large scale, international research program devoted to furthering the development of national Ecological Footprint accounting methodology.  相似文献

This paper investigates the role played by emerging Asia in the emergence and evolution of the global trade imbalances. Based on simulations in a general-equilibrium model of the world economy, we find that a productivity slowdown in the nontradable sector of these economies in the second half of the 1990s fits regional macroeconomic developments relatively well, but has limited spillover effect to the United States trade balance. In contrast, an increase in the desired level of emerging Asia net foreign assets starting in 2001 not only fits regional developments relatively well, but also has a significant spillover effect to the United States.  相似文献

This paper analyzes the effects of the form of ownership on the substitutability between internal and external sources of finance in Italy. In particular, we test whether financial constraints are more severe for independent firms compared to members of large national business groups and subsidiaries of foreign multinational corporations. The results obtained from flow of funds and investment equations estimated for a panel of Italian companies imply that independent firms face more severe financial constraints. In fact, not only members of national groups and subsidiaries of multinational corporations find it easier to substitute cash flow with external finance when the former falls but they do not display excess sensitivity to cash flow and debt in their investment decisions.  相似文献

In a vertically differentiated Cournot oligopoly where the high-quality variant of the good requires the use of high-quality labor, firms may either all supply the same quality or differentiate their product. In differentiated configurations the number of firms choosing to supply the high-quality variant is generally above the optimum. The opening of trade between symmetric countries entails a pro-competitive effect that raises welfare through a reduction in average quality. This result contrasts with previous findings concerning the opening of trade in vertically differentiated oligopolistic industries (Gabszewicz, Shaked, Sutton, and Thisse,International Economic Review 22 [1981]; Shaked and Sutton, in Kierzkowski, ed.,Monopolistic Competition and International Trade, Oxford 1984).  相似文献
