Using the USDA Healthy Eating Index, a nutrition index based on nutrient profiling, and a measure of calorie density, we compare the healthiness of food choices at home and away from home by two samples of consumers. Along with simple statistical procedures, we use a method employed by financial economists to evaluate mutual fund performance. Data are from the 2009–2010 and 2013–2014 NHANES food surveys. We find that consumers with healthier home diets tend to show less attention to nutrition when away from home. While this may reflect a lack of nutrition knowledge, we suggest they are also a reflection of deliberate choice, of regarding restaurant eating as a “treat,” as at least one survey has shown.  相似文献

Work‐family boundary research debates whether family demands should be integrated or separated from work demands. Our thesis is that the impact of boundary management preferences on business performance depends on the entrepreneur's gender. We also investigate how family‐to‐business support and business location alter the gender and boundary management preference interaction. Results show that an integration preference enhances business performance for men regardless of family‐to‐business support or business location. A segmentation preference aids women's business performance, especially among those with high family‐to‐business support and an independent business. An integration preference yields greater business performance for women with an at‐home business.  相似文献

The UK received its first sovereign credit ratings in 1978. Despite having required financial assistance from the International Monetary Fund only 18 months earlier, the British government managed to secure ‘triple‐A’ ratings from both Standard and Poor's and Moody's. Both assessments of creditworthiness reflected improving economic conditions but also British efforts to influence the sovereign ratings process. The Bank of England and the Treasury sought guidance from American investment banks to prepare for the ratings process and then controlled the flow of information available to the rating agencies accordingly, stressing the strengths of the national economy and downplaying the weaknesses. The British government subsequently launched its first bond issue in the New York market to high levels of investor demand. Consideration of these achievements complements the historiography concerning Britain's economic fortunes in the late 1970s. Scrutiny of events also offers a rare glimpse into the confidential sovereign ratings process. Both agencies relied on a combination of quantitative and qualitative evaluations of the UK. In addition, this article highlights the existence of a unique period in the history of sovereign credit ratings. From 1974 to 1985, the ratings industry enjoyed a cautious revival focused principally on ‘triple‐A’ borrowers.  相似文献

We take a setting in which upstream players produce design ideas and downstream players select among these ideas to develop finished products. Design diversity is valuable at the upstream stage and coordination is valuable at the downstream stage. However, this outcome is not always realized. We show that an intermediary between upstream and downstream can improve on equilibrium outcomes by acting as a coordination and commitment device whose optimal policy must sometimes reward inferior ideas. We apply the model to technology standards, trend‐driven industries, political primaries, and the management of process innovation. We discuss incentives to vertically integrate.  相似文献

Ronald Jones made seminal contributions to general‐equilibrium theory, moving away from an emphasis on the existence of equilibrium to algebraic formulations which enabled us to characterize key relationships between parameters and variables, such as that between tariffs and domestic factor prices and welfare. But the analysis remained limited in value for policy evaluation: the analysis was local, it provided only qualitative results, it was limited to very small models, and strictly interior solutions had to be assumed. The contribution of this paper is largely pedagogic and methodological. I show how the tools and approach pioneered by Jones can be generalized via the use of duality, complementarity and the Karush–Kuhn–Tucker theorem into a global, quantitative analysis of large changes in high‐dimensional models which also allows for regime changes and corner solutions. I then show how the resulting nonlinear complementarity problem directly translates into a numerical model using the General Algebraic Modeling System (GAMS).  相似文献

This paper examines whether corruption acts to “grease” or “sand” firms' exit. Corruption could facilitate exit when it is a tax that distorts markets, or it might retard exit when it empowers firms to obtain undue favors. Results, using panel data across US states and considering market exit and firms' death rates as dependent variables, show that greater corruption acts as grease rather than sand in that it facilitates firms' exit/death. In other findings, larger states, greater regulations, and more unemployment contributed to exit, as did some demographic aspects. Higher state minimum wages resulted in firms' death but not exit.  相似文献

This study investigates the association between CEO age and corporate tax planning. Using a sample of 11,537 firm‐year observations from the fiscal year 1997–2013, I find CEO age exerts an economically significant influence on firms’ tax policies, incremental to economic determinants identified in prior research. Specifically, CEO age is positively related to cash and GAAP effective tax rates, and negatively related to permanent book‐tax difference, suggesting that older CEOs are less likely to take actions to lower tax burden. The results hold across different model specifications and robustness tests to address potential bias arising from endogeneity, sample selection issue, and the confounding effect of CEO tenure.  相似文献

Several recent studies have used the upper echelons theory to explain the impact of personal traits of top executives on various corporate policies. In this, first of its kind, study we find that older executives invest more in working capital; take longer to convert inventories to cash; and pay their suppliers sooner. These findings are consistent with the argument that risk aversion increases with executive age. Our findings indicate that executive age has significant bearing on working capital management policies. This study also initiates new avenues in research relating behavioral aspect of executives with short‐term financial management.  相似文献
