We investigate the effect of physical activity on bodyweight and the gender differences in such effects, following the copula approach to endogenous switching regression. Using data from the 2006 Behavioral Risk Factor Surveillance System (BRFSS), we find differentiated effects of socio-demographic variables on exercise and on Body Mass Indexes (BMIs), and differentiated effects of exercise on BMI, between genders. Regular exercise, on average, decreases BMI by 1.78 for women and 1.01 for men. Food price away from home has negative effects on BMI of both men and women. 相似文献

Although numerous studies have highlighted the contributions of remanufacturing to sustainable development and the circular economy, the decision for a company to take up this strategy is riddled with uncertainties, especially when significant capital investment is involved. To improve the economic performance of a remanufacturing system in the face of uncertainties, we propose a methodological framework for flexible design of remanufacturing systems. Its application is demonstrated using a case study based on remanufacturing laptop computers for the Cambodian market. Through the case study, we show how one can explore the opportunity of setting up a remanufacturing system, study its economic feasibility and design flexible strategies to improve its economic performance in the face of uncertainties. More interestingly, we demonstrate how Monte Carlo simulation can be used to evaluate the effectiveness of different flexible design strategies in dealing with the uncertainties.

Abstract: Recent theoretical work argues that information risk is a non-diversifiable risk factor that is priced in the capital market. Using accruals quality to proxy for information risk, Francis et al. (2005) provide empirical support for this argument using a sample of US firms. This paper re-examines the interplay of accruals quality, information risk and cost of capital in Australia, where a number of important institutional and regulatory differences are hypothesized to affect the relation between accruals quality and cost of capital. The results suggest that, while accruals quality impacts on the cost of capital for Australian firms, some salient differences exist. In contrast to findings for US firms, the costs of debt and equity for Australian firms are largely influenced by accruals quality arising from economic fundamentals (i.e., innate accrual quality) but not discretionary reporting choices (i.e., discretionary accrual quality). This finding is consistent with our predictions based on the Australian institutional and regulatory environment. In addition, using both the asset pricing tests in Francis et al. (2005) and Core et al. (2008) , we provide evidence consistent with accruals quality being a priced risk factor. 相似文献

The relationship between Food Stamp Program (FSP) participation and household food insecurity (FI) is investigated using data from the 1996–1997 National Food Stamp Program Survey. Endogeneity of FSP participation is accommodated with an instrumental variables approach. In contrast to other findings reported in the literature, results suggest participation in the FSP reduces the severity of FI. Sociodemographic variables play important roles in FSP participation and FI. Underreporting of FSP participation and limited observations of food-insecure households in previous studies may have also been factors. 相似文献

We provide methodologies to price discretely monitored exotic options when the underlying evolves according to a double exponential jump diffusion process. We show that discrete barrier or lookback options can be approximately priced by their continuous counterparts’ pricing formulae with a simple continuity correction. The correction is justified theoretically via extending the corrected diffusion method of Siegmund (1985). We also discuss the jump effects on the performance of this continuity correction method. Numerical results show that this continuity correction performs very well especially when the proportion of jump volatility to total volatility is small. Therefore, our method is sufficiently of use for most of time. 相似文献

Many previous studies of US cigarette and alcohol consumption have focused on single equations. However, the addictive nature of consumption suggests that it is more appropriate to model these products as a system. We propose a two-step estimation procedure and apply the procedure to a system of equations for cigarette, beer and wine consumption. Results differ from those derived from an existing two-step procedure. Findings suggest that consumption of cigarettes, beer and wine is responsive to income changes but the elasticities are rather small. Personal physiques, education, age, race, ethnicity, health, gender, employment status, and regions also play significant roles in consumption. 相似文献

A censored system of household fat and oil demand equations is estimated with a two-step procedure, using cross-sectional data from the 1987–1988 US Nationwide Food Consumption Survey. Own price and total expenditure elasticities are close to unity and there is no evidence of gross substitutability. Compensated elasticities suggest net substitution among the products considered. 相似文献

The purpose of this study is to explore the relationship between work values and career orientation for employees in high-tech production. The importance of the high technology industry, acknowledged to be at the most advanced stage of highly developed technology presently available, and is often referred to as micro-electronics, rather than other technologies, has been widely recognized in recent years as it has become a key area in the economic development of Taiwan. As the high-tech industry is capital intensive, has high value-added products and requires a greater number of outstanding professionals, the ultimate criterion for human resources management is critical for companies involved in high technology research and development and manufacturing. The conclusion was used by the study to offer practical and academic recommendations. 相似文献
