Exporting involves sunk costs, so some firms export whilst others do not. This proposition derives from a number of models of firm behavior and has been exposed to microeconometric analysis. Evidence from the latter suggests that exporting firms are generally more productive than nonexporters. They self‐select, in that they are more productive before they enter export markets, but the evidence suggests that entry does not make them any more productive. This paper investigates exporting and firm performance for a large panel of UK manufacturing firms, applying matching techniques. The authors find that exporters are more productive and they do self‐select. In contrast to other evidence, however, exporting further increases firm productivity. 相似文献

We compare different contingent valuation question formats with each other and with observed behaviour for a non-monetary estimation task, the expected number of kilometers travelled by automobile. Open-ended questions, open-ended follow-up questions, dichotomous choice (DC) questions, and double-bound DC questions are included. The single and double-bound DC questions result in an estimated mean about twice as high as the actual value and the open-ended mean. The DC question overestimation seems to be due to an anchoring effect leading to yea-saying behaviour. Our results about the difference between DC questions and open-ended questions is consistent with the pattern observed in contingent valuations studies of the willingness to pay. Our results indicates that DC questions seem to be associated with a general overestimation problem that is present even for simple non-monetary estimation tasks. 相似文献

Natural resources, capital accumulation and the resource curse 总被引:2,自引:0,他引:2
Richard M. Auty 《Ecological Economics》2007,61(4):627-634
Early concern by economists for the effect of natural capital on economic growth gave way to complacency and neglect during the nineteenth century. Evidence has emerged, however, that since the 1960s the economic performance of low-income countries has been inversely related to their natural resource wealth. This relationship is not a deterministic one so policy counts. SEEA can help improve the policy and performance of resource-abundant low-income countries by reinforcing the rationale for the sound management of natural resources and also by providing an index of policy sustainability in the form of the net saving rate. This policy index, along with other measures such as a capital fund for sterilizing the rent, initiatives to increase the transparency of rent flows and the rigorous evaluation of alternative uses of additional public sector revenue can improve the efficiency by which natural resource rent is transformed into alternative forms of capital to sustain rising social welfare. Chad and Mauritania provide case studies to illustrate how SEEA and net saving can be used to diagnose policy failure and improve economic performance. 相似文献

In little more than a century life expectancy has doubled in most parts of the world. Neither facts nor theory support the view that this Mortality Revolution is due to the Industrial Revolution and the era of rapid economic growth that ensued. Rather, both revolutions mark the onset of accelerated and sustained technological change in their respective areas. They occur largely independently of each other, the later occurrence of the Mortality Revolution being due to the later development of biomedical vis-a-vis physical knowledge. Comparative study of the two should prove fruitful. Although entrepreneurship is important in each, there appear to be differences in the underlying motivations and the role of private property and other institutions. Links between technological change, on the one hand, and scale of operation, capital inputs, and education, on the other, also offer promising possibilities for comparative study.The author is grateful to Donna Hokoda Ebata and Christine M. Schaeffer for excellent assistance, the University of Southern California for financial support, and to Eileen M. Crimmins, Samuel H. Preston, Morton O. Schapiro, Roger S. Schofield, and two referees for helpful comments. 相似文献

Successful innovation and diffusion of technology can be attributed to the identification of the orbit of emerging new technologies that complement or substitute for existing technologies. This dynamism resembles the co-evolution process in an ecosystem. In an ecosystem, in order to maintain sustainable development, the complex interplay between competition and cooperation, typically observed in predator-prey systems, create a sophisticated balance. Given that an ecosystem can be used as a masterpiece system, this sophisticated balance can provide suggestive ideas for identifying an optimal orbit of competitive innovations with complement or substitution dynamism.Prompted by such a sophisticated balance in an ecosystem, this paper analyzes the optimal orbit of competitive innovations and, on the basis of an application of Lotka-Volterra equations, it reviews substitution orbits of Japan's monochrome to color TV system, fixed telephones to cellular telephones, cellular telephones to mobile Internet access service, and analog to digital TV broadcasting. On the basis of substitution orbits analyses, it attempts to extract suggestions supportive to identifying an optimal policy option in a complex orbit leading to expected orbit.Key findings include policy options that are effective in controlling parameters for Lotka-Volterra equations leading to expected orbit. 相似文献

Since the passage of the Science and Technology Basic Law in 1999, Taiwanese universities have taken a more “scientific-economic” approach to protect and commercialize their research. This research mainly examines innovation activities such as patenting, licensing, and incubated startups in the context of Taiwanese higher education institutions (HEIs). The “scientific-economic” framework used to analyze the strategic aspects influencing these academic innovations includes (1) intellectual property managerial capabilities, (2) the strength of external industrial partnerships, (3) the university entrepreneurial orientation, and (4) government research policy. Four hypotheses were developed. Data were collected via a questionnaire with all 122 HEIs in Taiwan surveyed.The research reveals that the aspects of intellectual property managerial capability, HEI-industry partnerships, and academic entrepreneurial orientation are useful to distinguish the university's innovation performance on patent grants, licensing incomes, and firm incubation. Also, government support on research plays a moderating role in academic innovation. Managerial and policy implications for managing innovation effectively in universities were drawn. 相似文献

AbstractBackground and aims: A wide range of treatment options are available for hepatocellular carcinoma (HCC), including systemic treatment with tyrosine kinase inhibitors (TKIs) such as sorafenib and lenvatinib, immunotherapies, locoregional therapies such as selective internal radiation therapy (SIRT) and treatments with curative intent such as resection, radiofrequency ablation and liver transplantation. Given the substantial economic burden associated with HCC treatment, the aim of the present analysis was to establish the cost of using SIRT with SIR-Spheres yttrium-90 (Y-90) resin microspheres versus TKIs from healthcare payer perspectives in France, Italy, Spain and the United Kingdom (UK).Methods: A cost model was developed to capture the costs of initial systemic treatment with sorafenib (95%) or lenvatinib (5%) versus SIRT in patients with HCC in Barcelona Clinic Liver Cancer (BCLC) stages B and C. A nested Markov model was utilized to model transitions between progression-free survival (PFS), progression and death, in addition to transitions between subsequent treatment lines. Cost and resource use data were identified from published sources in each of the four countries.Results: Relative to TKIs, SIRT with SIR-Spheres Y-90 resin microspheres were found to be cost saving in all four country settings, with the additional costs of the microspheres and the SIRT procedure being more than offset by reductions in drug and drug administration costs, and treatment of adverse events. Across the four country settings, total cost savings with SIR-Spheres Y-90 resin microspheres fell within the range 5.4–24.9% and SIRT resulted in more patients ultimately receiving treatments with curative intent (4.6 vs. 1.4% of eligible patients).Conclusion: SIR-Spheres Y-90 resin microspheres resulted in cost savings relative to TKIs in the treatment of unresectable HCC in all four country settings, while increasing the proportion of patients who become eligible for treatments with curative intent. 相似文献

A bstract . Of the many interesting pieces of information that can be found in Parsons's March 10, 1973 seminar at Brown University, one concerns his relationship to Schumpeter, and it is to this that this brief note is devoted. Parsons and Schumpeter knew each other for some 20 years, and one of the many things that Schumpeter taught Parsons was that one can read the texts of economists for the sociological insights that they contain. In Parsons's formulation from the seminar: "economists must have some sociological ideas." 相似文献

Changing trends and the nature of the work force dictate increased personal responsibility by employees and expanded use of
self-management practices. Nevertheless, organizations also feel the need to maintain external control. We propose a progressive
view of accountability theory which can resolve the dilemma of how internal and external control can effectively coexist.
Success of accountability forces is determined primarily by the relationship between the principal (party to whom one is accountable)
and the agent (employee). The agent’s felt responsibility is enhanced to the extent that accountability leads to the structuring
of expectations, the agent’s perceptions of the task or activity as significant, and the agent’s perception of control over
the situation. Propositions that may be used to guide future research are offered throughout the article. 相似文献
