Will Eating More Vegetables Trim Our Body Weight? AgEcon
Wendt, Minh; Lin, Biing-Hwan.
The purpose of the study is to examine the dietary consequences of greater consumption of vegetables by type and source. Dietary outcomes include calorie intake, USDA’s healthy eating index (HEI) scores, and intakes of fiber and sodium. We fit a fixed-effects model with two-day intake data from the 2003-4 National Health and Nutrition Examination Survey. Our results suggest that the effect of vegetable consumption on diet varies greatly by type of vegetables and where the food is prepared. As stated in the 2010 Dietary Guidelines for Americans, ―Eating [vegetables and fruits] instead of higher calorie foods can help adults and children achieve and maintain a healthy weight. Our results support the statement and call for attention to how to incorporate...

The Impact of Food Away from Home on Adult Diet Quality AgEcon
Todd, Jessica E.; Mancino, Lisa; Lin, Biing-Hwan.
Food away from home (FAFH) has been associated with poor diet quality in many studies. It is difficult, however, to measure the effect of FAFH on diet quality since many unobserved factors, such as food preferences and time constraints, influence not just our choice of where to eat but also the nutritional quality of what we eat. Using data from 1994-96 and 2003-04, this study applies fixed-effects estimation to control for such unobservable influences and finds that, for the average adult, FAFH increases daily caloric intake and reduces diet quality. The effects vary depending on which meals are consumed away from home. On average, breakfast away from home decreases the number of servings of whole grains and dairy consumed per 1,000 calories and...

The Cost of Environmental Protection AgEcon
Morgenstern, Richard D.; Pizer, William A.; Shih, Jhih-Shyang.
Expenditures for environmental protection in the U.S. are estimated to exceed $150 billion annually or about 2% of GDP. This estimate, based on largely self-reported information, is often cited as an assessment of the burden of current regulatory efforts and a standard against which the associated benefits are measured. Little is known, however, about how well reported expenditures relate to true costs. The potential for both incidental savings and uncounted burdens means that actual costs could be either higher or lower than reported expenditures. A significant literature supports the notion that increases in reported environmental expenditures probably understate actual economic costs. Estimates of the true cost of a dollar increase in reported...
