Efforts to improve public agricultural research efficiency include calls to increase use of competitive grants. This paper empirically assesses different instruments the USDA uses to fund state-level research. Compared with other instruments, competitive grants focus more on basic research and are concentrated among fewer states. Model results suggest that top-ranked biology and agricultural science programs were strong determinants of states' shares of competitive grants. Other significant factors were agricultural sector size and number of agricultural scientists. USDA-funded state-level research focus did not change significantly because competitive grants comprised only 15% of these funds and other instruments counteracted their influence.  相似文献

Despite considerable attention to the creative process and its relationship with personal characteristics, there is no published study focused directly on the relationship between the recently recognized core construct of psychological capital (PsyCap) and creative performance. Drawing from a large (N = 899) and heterogeneous sample of working adults, this study investigates PsyCap and its components (i.e., efficacy, hope, optimism, and resilience) as predictors of creative performance. Overall PsyCap predicted creative performance over and above each of the four PsyCap components. Theoretical and practical implications of these findings are considered. Copyright © 2010 ASAC.

Chicago and its suburbs are experiencing an increasing demand for water from a growing population and economy and may experience water scarcity in the near future. The Chicago metropolitan area has nearly depleted its groundwater resources to a point where interstate conflicts with Wisconsin could accompany an increased reliance on those sources. Further, the withdrawals from Lake Michigan is limited by the Supreme Court decree. The growing demand and indications of possible scarcity suggest a need to reexamine the pricing policies and the dynamics of demand. The study analyses the demand for water and develops estimates of scarcity rents for water in Chicago. The price and income elasticities computed at the means are -0.002 and 0.0002 respectively. The estimated scarcity rents ranges from $0.98 to $1.17 per thousand gallons. The results indicate that the current prices do not fully account for the scarcity rents and suggest a current rate with in the range $1.53 to $1.72 per thousand gallons.  相似文献

This paper explores the patterns of citations among patents taken out by inventors in the U.S., the U.K., Francc. Germany and Japan. We find (I) patents assigned to the same firm are more likely to cite each other, and come sooncr than other citations; (2) patents in the same patent class are approxinlatcly 100 titlles as likely to cite each other as ydtents froin different patent classes, but there is not a strong time pattern to this effect; (3) patents whose inventors reside in the same country are typically 30 to 80% more likely to cite each other than inventors from othcr countrics, and these citations come sooner; and (4) there are clear country-specific citation tendencies, e.g., Japanese citations typically come sooner than those of othcr countries.  相似文献

Informal trading in the global South, particularly in Latin America, is the subject of revanchist urban policy and yet few studies have examined the longer‐term impacts of such intolerant policies on traders. This article explores the evolution and impacts of revanchist policies directed at informal traders in the Andean city of Cusco. It makes two key contributions. First, it documents a shift from early revanchist policies to a post‐revanchist era where policies have become more tolerant of informal traders. However, contemporary policies fall short of a supportive environment for informal trading, hence the authors recommend changes that will ensure informal traders can access the city's streets and become an accepted part of the urban fabric. Second, given the lack of theoretical attention given to the impacts of revanchism, a battlegrounds framework is developed, consisting of spatial, political, economic and socio‐cultural battlegrounds. This framework provides a comprehensive insight into the complex set of interactions that exist between informal traders and the state. It is hoped that the framework will provide a tool for further research into the highly damaging impacts of revanchism across the globe.  相似文献

This paper demonstrates that a post-announcement earnings drift, which is often advanced as an example of market irrationality, can arise even if traders act rationally on their information. Specifically, we show that in the presence of share supply variations which are unrelated to information, there is a positive correlation between the unexpected component of current public signals and future price changes. Such a correlation arises from the fact that while prices reveal private information that cannot be found in public signals, non-information based trading distorts the information content of prices relative to the implications of both private and public information. Under these circumstances, markets may appear semi-strong inefficient and slow to respond to earnings announcements even though information is processed in a timely and efficient manner. Our findings correspond well with previously documented empirical evidence and suggest that the robustness of earnings-based anomalies may be rational outcomes of varying uncertain share supply.  相似文献

We investigate how, in an open economy, carbon taxes combined with output‐based rebating (OBR) perform in interaction with the carbon policies of a large neighbouring trading partner. Analytical results suggest that, whether the purpose of the OBR policy is to compensate firms for carbon tax burdens or to maximize welfare (accounting for global emission reductions), the OBR rate should be positive in policy‐relevant cases. Numerical simulations for Canada, with the US as the neighbouring trading partner, indicate that the impact of US policies on the OBR rate will depend crucially on the purpose of the Canadian OBR policies. If, for a given US carbon policy, Canada's aim is to restore the competitiveness of domestic emission‐intensive and trade‐exposed (EITE) firms to the same level as before the introduction of its own carbon taxation, we find that the necessary domestic OBR rates will be insensitive to the foreign carbon policies. However, if not only the Canadian carbon tax but also an equally high US tax is introduced, compensatory Canadian OBR rates will be up to 50% lower, depending on the sector and on US OBR policy. If the policy objective is to increase economy‐wide allocative efficiency (welfare) of Canadian policies by accounting for carbon leakage, the US policies will have only a minor downward pressure on desirable OBR rates in Canada. Practical choices of OBR rates hardly affect overall domestic economic performance; thus, output‐based rebating qualifies as an instrument for compensating EITE industries without a large sacrifice in terms of economy‐wide allocative efficiency.  相似文献

The artifice of an infinitely-lived representative agent iscommonly invoked to balance the present costs and future benefitsof climate stabilization policies. Since actual economies arepopulated by overlapping generations of finite-lived persons,this approach begs important questions of welfare aggregation.This paper compares the results of representative agent andoverlapping generations models that are numerically calibratedbased on standard assumptions regarding climate--economyinteractions. Under two social choice rules -- Pareto efficiencyand classical utilitarianism -- the models generate closelysimilar simulation results. In the absence of policies toredistribute income between present and future generations,efficient rates of carbon dioxide emissions abatement rise from15 to 20% between the years 2000 and 2105. Under classicalutilitarianism, in contrast, optimal control rates rise from 48 to 79% this same period.  相似文献

We examine the impact of venture capitalist (VC) involvement, quality and exit on corporate governance structures at the time of and subsequent to an initial public offering (IPO). Venture capital backed firms utilize governance structures with greater levels of monitoring at the time of an IPO compared to non-backed firms, but this difference begins to dissipate over time. While short-lived, IPOs backed by high quality VCs have greater overall monitoring levels than those IPOs backed by low quality VCs. IPOs backed by high quality VCs use significantly more equity-based compensation than their low quality counterparts. Finally, the exit of a VC materially alters the governance structure of firms. Measures of governance decline following the departure of a venture capital firm. Overall, the presence of a venture capitalist affects governance structures of firms both at the IPO and through the early years as public firms.  相似文献

MNCs have been conceptualized as differentiated networks that, in turn, are embedded in external networks. Previous research has predominantly focused on the embeddedness of established subsidiaries into their local environment, omitting to shed light on the phenomenon of headquarters linkages to the local context which creates embeddedness overlap. We develop a model of why MNCs develop overlapping linkages to local subsidiary networks even if the subsidiaries have grown out of the initial start-up phase. Using detailed information on 168 European subsidiaries, we find that MNCs build and maintain more overlapping network ties when subsidiaries are high performers, hold important resources, operate in turbulent environments, and are closely connected to multinational actors as opposed to purely domestic firms.  相似文献
