University–industry technology transfer (TT) has become increasingly institutionalized and is supported by numerous reforms and initiatives at the national, regional and university levels. Most countries have implemented a policy mix involving a range of instruments to support the commercialization of research. Still, there is no systematic evidence indicating why the mix of policy instruments differs between countries. This study offers a novel cross-national investigation of the policy mix emphasizing the level of centralization and decentralization of policy instruments. We map and analyze two specific types of public instruments aimed at addressing the so-called funding gap in TT: proof of concept programs (POCs) and university-oriented seed funds (USFs). Based on a survey across 21 European countries, we find that such instruments are widely used but are organized differently depending on the level of implementation of TT practices in the country and the specific type of instrument considered. More precisely, we find a U-shaped relationship between the use of centralized gap-funding instruments and the country’s implementation of TT practices. Moreover, the type of gap-funding instrument (POC or USF) moderates this relationship. We discuss the implications of our findings and suggest that the policy mix of gap-funding instruments evolve with the maturity of the national TT infrastructure.  相似文献

In cases where policy makers accept ``bribes'' offered by organised lobbies or interestedparties, government decisions can be modelled as a first price menu auction. In this paper we adaptthis structure to model debt repudiation. We considera one-period model in which two generations, parents and children, are present, and debt titles are unevenlydistributed among parents. The government can repaythe debt by a combination of taxes on the children'sincome and on the outstanding debt. We excludeintergenerational conflicts, assuming that the parents'and children's objective is to maximise the utility ofthe family. In this perspective, families make offersthat relate monetary contributions to the taxstructures chosen by the government. On the hypothesisthat all interests are represented, we obtain theresult that the government is indifferent to the taxstructure.  相似文献

Abstract This paper uses a sample of professional engineers employed in the public and private sector to investigate the effect of sector employment, indicators of task complexity, organization size, number of rules, importance, and attentiveness and agreement among various principals (customers or clients, peers, mid‐ and top‐level management, and politicians) on both employee discretion and a subjective measure of employee productivity. The results show that disagreement among important and attentive proximate principals (mid‐level managers) expands discretion, but disagreement among important and attentive distant principals (top executives and politicians) reduces discretion. Sector has no direct or indirect effect on discretion. When customers or clients and peers are important and attentive principals, discretion increases, and so does productivity. Monitoring by mid‐level management has no effect on productivity. Because disagreement among distant principals is greater in the public sector, devolution of authority alone is unlikely to increase public sector productivity. © 2000 by the Association for Public Policy Analysis and Management.  相似文献

We develop a local labor market information system to assess the labor market effects of recently adopted welfare reform laws. Using the Cleveland-Akron metropolitan area as a prototype, we develop an occupationally and geographically specific inventory of projected job openings and measure the skill mismatch between projected job openings and the welfare population likely to enter the labor market. We find the skill mismatches are quite large: Following implementation of reform, welfare recipients entering the labor force would initially have to claim anywhere from 34 to 61 percent of expected low-skill job openings in order to become fully employed. Labor market opportunities are further diminished if one takes into account the effect of gender and space in limiting job accessibility. Welfare recipients entering the labor market as a result of reform would require from 40 to 75 percent of jobs remaining if predominately male occupations are removed from consideration. The AFDC recipients who depend on public transportation, even in extraordinarily long commutes, can access only 40 to 44 percent of entry-level job openings. © 1998 by the Association for Public Policy Analysis and Management  相似文献

This article focuses on the evolving nature of the foreign policy of the European Union (EU) towards Brazil, which gained momentum and became more dynamic and denser after the establishment of a formal strategic partnership (SP) in 2007. It provides a historical overview of the institutional relations between Brussels and Brasília, before proceeding with an analysis of the main drivers behind this novel development. The study goes on to offer a critical examination of the implementation of the EU–Brazil SP by casting light on both its major achievements and the challenges it has faced. It concludes that the establishment of a formal strategic partnership with Brazil has contributed to the strengthening of the EU’s globally oriented partnership policy and ultimately to the incremental empowerment of the EU necessary to the assertion of its values, objectives and interests on the international stage.  相似文献
