It is demonstrated that adaptive learning in the least squares sense may be incapable of satisfactorily reducing the number of attainable equilibria in a rational expectations model when focusing on the forward‐solutions to the model. The model examined, as an illustration, is a basic asset pricing model for exchange rate determination that is augmented with technical trading in the currency market in the form of moving averages since it is the most commonly used technique according to questionnaire surveys. The forward‐solutions to such a model are preferable to the backward‐solutions that are normally utilized since announcement effects is an important feature in currency trade. Because of technical trading in foreign exchange, the current exchange rate depends on j max lags of the exchange rate, meaning that the model has j max+1 rational expectations equilibria, where several of them are adaptively learnable in the least squares sense. However, since past exchange rates should not affect the current exchange rate when technical trading is absent, it is possible to single out a unique equilibrium among the adaptively learnable equilibria that is economically meaningful. It is worth noting that the model examined can also be viewed as a model for stock price determination in which the forward‐solutions to the model are preferable to the backward‐solutions since the importance of announcement effects is a common characteristic for currency and stock markets.  相似文献

高等教育工作努力的方向应以探索教育的发展规律、发展思路、突出学校特色优势为重点内容。人民满意的教育说到底就是在多元质量观照下的适需教育,这要求高等教育管理实践中应强调“去行政化”管理方式、发展“生态文化”的价值定位及“内涵式发展”道路。同时,既要遵循“有所为有所不为”的教育发展思路,又要处理好满足需要与开发潜能、人才培养模式与求真务实之间的关系。  相似文献

This paper explores the relationship between risk and innovation in public services, presenting the state of the literature across different disciplines and the academic and policy literature. It suggests a novel framework to approach risk, emphasising the importance of differentiating between different types of risk and risk management. The paper offers a typology of risk types and management approaches that indicates different effects on the type of public service innovation. It concludes by considering the implications for theory and practice.  相似文献

Slow growth over the last decade has prompted policy attention towards increasing R&D spending, often via the tax system. We examine the impact of R&D on firm performance, both by the firm's own investments and through positive (and negative) spillovers from other firms. We analyse panel data on US firms over the last three decades, and allow for time‐varying spillovers in both technology space (knowledge spillover) and product market space (product market rivalry). We show that the magnitude of R&D spillovers remains as large in the second decade of the 21st century as it was in the mid 1980s. Since the ratio of the social return to the private return to R&D is about four to one, this implies that there remains a strong case for public support of R&D. Positive spillovers appeared to temporarily increase in the 1995–2004 digital technology boom. We also show how these micro estimates relate to estimates from the endogenous growth literature and give some suggestions for future work.  相似文献

This paper explores the determinants of financial development by focusing on the role played by barriers to the diffusion of financial technology. These barriers are measured using human genetic distance from the technology frontier. The results based on cross-sectional data for 123 countries suggest that genetic distance to the global frontier has an economically and statistically significant effect on financial development, in that countries that are genetically far from the technology leader tend to have lower levels of financial development. Genetic distance is found to have the largest effect, even after controlling for other determinants of financial development established in the literature. These findings indicate that cultural barriers to the diffusion of financial technology across borders impact financial development by influencing the follower countries’ ability to adopt and adapt innovations from the frontier.  相似文献

本文在省际面板数据基础上运用DEA分析中的Malmquist指数方法测算并分解了我国改革开放以来的TFP变动。结果发现:就TFP变动模式而言,1978~2006年间TFP每年以接近3%的速度增长,TFP增长率波动呈现收敛态势,近年未现明显下滑趋势;就TFP增长的构成而言,技术效率变化与技术进步间存在替代关系,1980年代技术进步和技术效率变化交替起主导作用,1990年代以来TFP增长主要由技术进步推动;就地区特征而言,东部和内陆资源丰富省份TFP增长较快,而中部省份的TFP增长较慢。  相似文献

Based on original data on Italian firms specializing in medium‐ and low‐tech industries, we study the relationship between firms’ upstream and downstream internationalization and their propensity to introduce products or processes that reduce environmental impact. Preliminary evidence suggests that geography plays an important role in green firms’ activities and supply chains. More precisely, results suggest that firms that outsource to and rely on non‐local suppliers are less likely to engage in environmental innovations. Moreover, we verify that firms engaged in export activities play a similar and negative role, regardless of the export intensity and typology of foreign markets (i.e. developed versus emerging). Tapping global flows of knowledge by being a part of a multinational group positively spurs the development of green innovations, as for FDIs.

According to the literature, multinational firms are motivated to locate R&D activity overseas for mainly three reasons, namely: to adapt to local markets; access lower cost R&D capacity; or access unique research capability. Ireland at the beginning of the century appeared, from this finding, badly placed to attract R&D in foreign direct investment (FDI), as it had by global comparisons neither a large domestic market, a low cost economy nor a strong R&D profile. In spite of this, Ireland has succeeded in attracting significant investment in R&D projects. The cases of investment in Ireland analysed here reveal that the nature of the decision-making process itself has been a decisive factor in the outcome, and that less quantifiable factors such as cultural closeness, history, and personal relationships have played a stronger role in the outcome than would be expected from the literature.  相似文献
