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 examine the sophistication of analysts' cash flow forecasts to better understand what accrual adjustments, if any, analysts make when forecasting cash flows. As a preliminary step, we first demonstrate that prior empirical tests used to evaluate the sophistication of analysts' cash flow forecasts are not diagnostic. We then present three sets of evidence to triangulate our conclusion that analysts' cash flow forecasts incorporate meaningful accrual adjustments. First, we review a stratified random sample of 90 analyst reports and find that the majority of these analysts include explicit adjustments for working capital and other accruals in their cash flow forecasts. Second, using a large sample of analysts' cash flow forecasts from 1993–2008, we find that these forecasts outperform time‐series cash flow forecasts in correctly predicting the sign and magnitude of accruals. Finally, we find a significant market reaction to analysts' cash flow forecast revisions, suggesting that investors find these revisions informative. Collectively, our findings demonstrate that analysts' cash flow forecasts are not simply naïve extensions of their own earnings forecasts, but that they reflect meaningful and useful accrual adjustments. These findings are relevant to researchers who examine analysts' cash flow forecasts in a variety of settings, and to investors and practitioners who employ these forecasts for valuation purposes. 相似文献

We examine how information uncertainty surrounding IPO (initial public offering) firms influences earnings management and long‐run stock performance. For low‐information‐uncertainty issuers, at‐issue earnings’ management is positively related to subsequent unmanaged earnings and has no relationship to market reaction to earnings announcement and long‐run stock performance following the offering. For high‐information‐uncertainty issuers, however, at‐issue earnings’ management is unrelated to subsequent unmanaged earnings and negatively related to market reaction to earnings announcement and long‐run stock performance following the offer. The evidence suggests that, on average, managers in low‐information‐uncertainty firms tend to engage in earnings’ management for informative purposes, while managers in high‐information‐uncertainty firms engage in earnings’ management for opportunistic purposes. 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

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

Under the structure of multiple business entities, supply chain management (SCM) offers the external and internal integration
of business processes in enterprises. The most important objective of SCM is to enhance the supply chain performance such
as reinforcing the service level and increasing profit as well as reducing order cycle time and inventory. In recent years,
due to the advancement of information technology, enterprises can manage the product flow and the information flow via economical
and efficient mechanisms. The well-organized information sharing can enhance the supply chain performance and allow enterprises
to refine their strategies of supply chain in order to maximize their profits. The previous studies pointed out the positive
effect of information sharing on the efficiency of supply chain. However, relatively little literature focuses on the performance
analysis for multi-echelon supply chain with various information sharing scenarios. By using the simulation technique, this
paper models different scenarios of information sharing, and further analyzes the impacts of information quality on multi-echelon
supply chain performance. In addition, this paper employs Data Envelopment Analysis (DEA) to integrate multiple performance
measures to ensure the information sharing scenarios with enhanced performance. 相似文献

We examine the socio‐demographic determinants of fruit and vegetable consumption using household survey data from Malaysia. A bivariate ordered probability model is developed by the copula approach. Results for a system of fruit and vegetable servings per week indicate that education, age, ethnicity, income, location of residence, smoking status and health conditions are significant predictors of fruit and vegetable consumption in Malaysia. Policy implications are suggested. 相似文献

In a previous study based on a matched sample analysis, it is found that in Taiwan top management turnover rate for the listed firms in the presence of a proxy contest is much higher than the ones without a proxy contest. In other words, the hypothesis of job security has gained empirical support. Taking account of the proxy contest outcomes, the present study extends the sample years, i.e. 1994–1999, to further examine the impact of proxy contest on managerial turnover. In conformity with expectations, the major empirical findings can be summarized as follows: the highest turnover rate of top management is observed in the firms of which the dissidents win majority seats; the second highest turnover rate is observed in the firms of which the dissidents win some seats; whereas the lowest turnover rate is observed in the firms of which the dissidents win no seats. Empirical findings of this kind provide further support to the view that proxy contest has played an effective monitoring role in disciplining incumbent management.
