I. IntroductionIt is well known that China’s reform and open-up policy initiated in 1978 had an extremelylarge impact on the Chinese economy. This policy represented an about-face against thetraditional self-reconstruction strategy that China had maintained since the founding ofthe people’s Republic in 1949. Although China’s economy temporarily fell into confusionfor a few years after the Tian-an-men incident in 1989, China continued to record high GDPgrowth. Moreover, after Deng Xiao…  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

This article examines option pricing performance using realized volatilities with or without handling microstructure noise, non‐trading hours and large jumps. The dynamics of realized volatility is specified by ARFIMA(X) and HAR(X) models. The main results using put options on the Nikkei 225 index are that: (i) the ARFIMAX model performs best; (ii) the Hansen and Lunde (2005a) adjustment for non‐trading hours improves the performance; (iii) methods for reducing microstructure noise‐induced bias yield better performance, while if the Hansen–Lunde adjustment is used, the other methods are not necessarily needed; and (iv) the performance is unaffected by removing large jumps from realized volatility.  相似文献

In this paper, we analyze the determinants of corporate saving in the form of changes in cash holdings for 11 Asian economies using firm‐level data from the Oriana Database for the 2002–2011 period. We find some evidence that cash flow has a positive impact on the change in cash holdings (i.e. that the cash flow sensitivity of cash is positive) and that the positive impact of cash flow on the change in cash holdings is larger and more significant in the case of smaller and presumably more constrained firms than in the case of larger and presumably less constrained firms in both developed and developing economies. Both of these findings corroborate the importance of financial constraints in Asian firms. In addition, we find that the cash flow sensitivity of cash declined after the global financial crisis and that Tobin's q has a positive impact on the change in cash holdings, especially in the case of larger and presumably unconstrained firms.  相似文献

This paper examines misconfidence (over‐ or underconfidence) and marriage proposal strategies in a two‐sided search model with non‐transferable utility. Single agents are vertically heterogeneous—there exists a ranking of marital charm (types). It is shown that there are two externalities to over‐ or underconfident behaviour: someone's over‐ or underconfidence affects: (i) the duration of search for others who directly meet over‐ or underconfident agents; and (ii) the marriage decision of others who directly or indirectly meet over‐ or underconfident agents. Furthermore, these externalities prevent the lowest‐type agents from marrying in an equilibrium.  相似文献

Leadership programs in public health have been declining in numbers since 2012. The decline in training programs could be due to the lack of outcome‐based results and the lack of a manageable set of standardized skills needed for public health leadership. A comprehensive study was completed in two phases to determine if the current model of public health leadership institutes is effective at generating outcome‐based results. The following paper will focus on the first phase of the study. The first phase included a qualitative analysis to determine the domains, definitions, and skills needed to lead. An analysis of the skills, domains, definitions, and traits included in five established and commonly used leadership models/theories in public health leadership development (Transformational, Servant, Appreciative, Collaborative, and Emotional Intelligence leadership) plus the National Public Health Leadership Development Network (NLN) Leadership for Community Health, Safety & Resilience Competency Framework was completed. Of the 161 different skills, definitions, traits, and/or competencies from the five leadership models and the NLN competency framework, 123 were determined to be related to one of six domains needed for leadership and were defined into 21 skills. The findings could lead to more uniformity in public health leadership development and evaluation.  相似文献

Why was the Japanese consumer price index for rents so stable even during the period of the housing bubble in the 1980s? To address this question, we use a unique micro price dataset which we have compiled from individual listings (or transactions) in a widely circulated real estate advertisement magazine. This dataset contains more than 700,000 listings of housing rents over the last 20 years. We start from the analysis of microeconomic rigidity and then investigate its implications for aggregate price dynamics, closely following the empirical strategy proposed by Caballero (Caballero and Engel, 2007). We find that 90% of the units in our dataset had no change in rents per year, indicating that rent stickiness is three times as high as in the United States. We also find that the probability of rent adjustment depends little on the deviation of the actual rent from its target level, suggesting that rent adjustments are not state-dependent but time-dependent. These two results indicate that both the intensive and extensive margins of rent adjustments are small, resulting in a slow response of the CPI for rent to aggregate shocks. We show that the CPI inflation rate would have been higher by 1% point during the bubble period, and lower by more than 1% point during the period following the burst of the bubble, if Japanese housing rents were as flexible as those in the United States.  相似文献

This paper summarizes the results of personal exposure monitoring and estimates the risk from exposure to 18 volatile organic compounds compared with health criteria set by the US Environmental Protection Agency. In study 1, personal exposure levels and outdoor air concentrations were compared, and in study 2, personal exposure levels and the corresponding indoor air concentrations were compared. From these studies, it was concluded that personal exposure to volatile organic compounds depended markedly on indoor air quality and that handling of compounds increased personal exposure markedly. Risk estimations indicated that chloroform in tap water, benzene from cigarette smoke and p -dichlorobenzene from household insecticide needed caution.  相似文献
