I see a big growth potential for the US and Chinese biotechnology partnerships for the next years. US biotechnology sector is generating already more than $50 billion dollars. Chinese bio-technology will grow in the next 20 years to more than 11 billion yuan (US 1.33 billion) annually. 相似文献

In this article we examine individual differences in the desire for unique consumer products. We identify several of the antecedents and consequences of this variable and argue that a new scale to measure it is needed. Then we report the results of our efforts to develop and validate such a scale. The 8-item scale that emerged from these efforts is shown to be unidimensional, to have a factor structure that generalizes across student and nonstudent samples, and to have acceptable internal and test–retest reliabilities. The scale's validity is attested to by its theoretically intelligible relationships with other personality measures and by its ability to differentiate between the patrons of an artistic theater and a second-run theater. Finally, we discuss the potential uses of the scale in both basic and applied marketing research. © 1997 John Wiley & Sons, Inc. 相似文献

Using a panel of 69 countries during 1981 and 2005, we investigate the role of institutions in determining foreign direct investment (FDI). We find that institutions are a robust predictor of FDI and that the most significant institutional aspects are linked to propriety rights. Using a novel data set, we also study the impact of institutions on FDI at the sectoral level. We find that institutions do not have a significant impact on FDI in the primary sector but that institutional quality matters for FDI in manufacturing, and particularly in services. 相似文献

In this paper we test the well-known hypothesis of Obstfeld and Rogoff (NBER Macroeconomics Annual 7777:339–390, 2000) that trade costs are the key to explaining the so-called Feldstein–Horioka puzzle. Our approach has a number of novel features.
First, we focus on the interrelationship between trade costs, the trade account and the Feldstein–Horioka puzzle. Second,
we use the gravity model to estimate the effect of trade costs on bilateral trade and, third, we show how bilateral trade
can be used to draw inferences about desired trade balances and desired intertemporal trade. Our econometric results provide
strong support for the Obstfeld and Rogoff hypothesis and we are also able to reconcile our results with the so-called home
bias puzzle.

This study used a laboratory experiment with monetary incentives to test the impact of three personal factors (moral reasoning, value orientation and risk preference), and three situational factors (the presence/absence of audits, tax inequity, and peer reporting behavior), while controlling for the impact of other demographic characteristics, on tax compliance. Analysis of Covariance (ANCOVA) reveals that all the main effects analyzed are statistically significant and robustly influence tax compliance behavior. These results highlight the importance of obtaining a proper understanding of these factors for developing effective policies for increasing the level of compliance, and indicate that standard enforcement polices based on punishment alone should be supplemented by an information system that would acquaint tax payers with the compliance level of other tax payers; reinforce the concept of fairness of the tax system among tax payers; and develop programs that enhance and appeal to a taxpayer's moral conscience and reinforce social cohesion. 相似文献

In this paper, we re-examine the “PPP Puzzle” using sectoral disaggregated data. Specifically, we first analyse the mean reversion
speeds of real exchange rates for a number of different sectors in 11 industrial economies and then focus on relating these
rates to variables identified in the literature as key determinants of CPI-based real exchange rates, namely: the trade balance, productivity and the mark up. In particular, we seek to understand to what extent the relationships existing at the aggregate level are borne out at the
disaggregate level. We believe that this analysis can help shed light on the PPP puzzle.

Research on playfulness has long focused on children, while the study of its expression in adulthood has only recently been undertaken. This cross-sectional study investigated the interrelationship between playfulness in young adults, perceived stress, and styles of coping with 898 students from three universities. Findings revealed that playful individuals reported lower levels of perceived stress than their less playful counterparts, and more frequently utilized adaptive, stressor-focused coping strategies and were less likely to employ negative, avoidant, and escape-oriented strategies. The results suggested that playfulness serves a strong adaptive function with university students, providing them with specific cognitive resources from which they can manifest effective coping behaviors in the face of stressful situations. Speculation as to the role of playfulness in fostering resilience is encouraged, and further empirical research on the therapeutic benefits of playfulness should be undertaken from a causal perspective. 相似文献

Abstract This study investigates the risk inherent in defined contribution (DC) pension plans on an individual and aggregate basis, based on U.S. data. Our aim is to gain insight into the consequences of a DC pension scheme becoming the predominant pillar of retirement income for an entire society. Using the stochastic simulated output of a DC flexible age-of-retirement model, we first determine the optimal investment strategies. We then examine the demographic retirement dynamics of an entire population of DC pension plan participants. We observe that even for the most risk-averse plan members there is a high level of uncertainty in an individual’s age at retirement. At the aggregate population level, we find that this uncertainty does not get dampened to any great extent by a diversification effect. Instead, the central role played by the market in determining retirement dates results in significant variation in the dependency ratio (the ratio of retirees to workers) over time. In addition, an attempt to ameliorate the outcome by introducing additional realistic features in the DC population modeling did little to dampen this volatility, which suggests that countries dominated by DC schemes of this type may, over time, be exposed to significant risk in the size of its labor force. 相似文献

The research reported here aims to understand how people react to statements expressing risk uncertainty information in the context of a commonly experienced potential hazard, food related risks. Public perception of seriousness of risk for themselves, and for other people was examined for different types of uncertainty, for each of five different food hazards. The results indicated that participants responded to the different types of uncertainty in a uniform way, suggesting that perception of risk associated with uncertainty is not affected by the 'type' of uncertainty. The results further indicated that the seriousness of risk, in the presence of statements of uncertainty, was perceived to be greater for pesticides and genetic modification compared to BSE, high fat diets and Salmonella . It was argued that this could be due to the perceptions of low personal control, and high societal responsibility to protect people and societal control over exposure to the potential risks of pesticides and genetic modification. Under circumstances where people feel they have little personal control over their exposure to a particular hazard, and those social institutions that are perceived to be in control of protecting the public indicate that there is uncertainty associated with risk estimates, the hazard may appear to be 'out of control', which is associated with a perception of serious risk. 相似文献
