Learning the true calorie content of fast food may induce consumers to change behavior, yet recent evidence is mixed on whether calorie labels cause consumers to order healthier meals. Especially for individuals for whom consumption of highly caloric fast-food is habitual, a rational response to calorie labeling may instead be to maintain consumption levels but increase physical activity. Using American Time Use Survey data from 2004 to 2012, we show that the 2008 New York City Calorie Labeling Mandate significantly improved several measures of physical activity, including overall metabolic equivalents of task units and minutes of sedentary activity. Our results translate to an average extra 28 calories burned per day or a 0.6 kg weight decrease for the average person over one year. These results provide a plausible mechanism for calorie labeling mandates to lower obesity rates, which we demonstrate in the New York City context.
This paper uses data on Ohio school districts to estimate the short and long term impact of different types of school expenditures on student outcomes. Our identification strategy employs a dynamic regression discontinuity design that relies upon the exogenous variation in public school funding created by marginally approved or failed local referenda to fund Ohio schools. We find that additional school expenditures on operating, minor capital, and major capital expenditure categories do not have a statistically significant effect on the student test scores of the average public school. Importantly, however, operating expenditures have a large and statistically significant impact on student performance in higher poverty school districts. We also examine possible channels (e.g., class size, attendance, discipline, and teachers’ compensation) through which each type of expenditure may affect outcomes, and we find that teachers’ compensation is the only channel that is affected by additional operating and minor capital expenditures.
This paper attempts to interpret the Bartholomew (1973) index of mobility in terms of a directional mobility index based on the one-step expected states of movement corresponding to a specific state of transition matrix. A partial ordering of directional mobility of a general state of transition matrices, referred to as “upward mobility favoring sequential averaging (UMFSA),” is proposed using the algebraic equivalent of the generalized Lorenz ordering of expected states. When the underlying mobility depends on the initial distribution of the states, using a Bayesian approach, the indices are reexamined for a general class of matrices. This enables us to interpret the Prais (1955) and Bibby (1975) mobility index in this framework.
The role of diet in health is well established and, in the past decade, more attention has been given to the role of food choices in the environment. The agricultural sector produces about a quarter of the world’s greenhouse gas emissions (GHGE), and meat production, especially beef, is an important contributor to global GHGE. Our study aimed to address a fundamental gap in the diet-climate literature: identifying consumers who are receptive to making dietary changes, and the effect of their potential changes on GHGE, diet healthfulness, and diet costs.
Dietary data on US individuals from a nationally representative survey were linked to food-related GHGE. We identified individuals receptive to changing their diets (potential changers) as those who reported trying US dietary guidance and were likely to agree that humans contribute to climate change. We assessed GHGE, diet healthfulness measured by the Healthy Eating Index (HEI), and diet costs before and after hypothetical changes replacing either beef or meats with poultry or plant-protein foods.
Our sample comprised 7188 individuals, of whom 16% were potential changers. These were disproportionately women, highly educated, or had higher income compared with individuals deemed not likely to change. Replacing 100% of beef intake in potential changers with poultry reduced mean dietary GHGE by 1·38 kg CO2-equivalents per person per day (95% CI 1·19–1·58), a 35·7% decrease. This replacement also increased mean HEI by 1·7% and reduced mean diet costs by 1·7%. We observed the largest changes when replacing all beef, pork, or poultry intake with plant-protein foods (GHGE decreased by 49·6%, mean HEI increased by 8·7%, and dietary costs decreased by 10·5%). Hypothetical replacements in the potential changers alone resulted in whole population reductions in 1-day dietary GHGE of 1·2% to 6·7%, equivalent to 22–126 million fewer passenger vehicle km.
Individual-level diet studies that include a variation in response by consumers can improve our understanding of the effects of climate policies such as those that include sustainability information in national dietary guidance. In our study, we found that changes by a small percentage of motivated individuals can modestly reduce the national dietary GHGE. Moreover, these substitutions can modestly improve diet healthfulness and reduce diet costs for individuals who make these changes.
The odds of experiencing a public mass shooting in first person are low. Approximately 411 people have died in such tragic events during the past decade in the United States. However, the high saliency of mass shooting events might induce changes in behavior that may pose an external cost on society. In this paper, I estimate the impact of indirect exposure to high profile acts of violence on behavior by using information on 45 mass shootings from 2003 to 2016. Using individual-level data, I find that being within 250 miles shortly after a mass shooting, individuals overall activity levels decrease by 1.7 percent. This decline is equivalent to a daily 16 minute walk. For an average weight person, this decline would mean 50 less calories burned per day. The decline in activity is mainly explained by a 10 percent decrease in minutes of moderate to vigorous activities and are driven mostly by individuals under 30. In addition to a decrease in activity levels, I find an increase in the probability of having more days where perceived mental health is poor. And interestingly, I find and an increase in the probability of binge drinking. Finally, I also find a statistically significant decrease of 15.6 minutes worked per week shortly after a mass shooting has occurred. These results show that aside from direct victims, mass shootings also impact the short-term behavior of a broader portion of the population.
We use calorie-labeling laws to investigate the effect of information disclosure on health behavior and outcomes. Unlike previous studies looking at all adults; we focus on pregnant women, a subpopulation that is likely to be more sensitive to new dietary information. We use Natality Data and employ a difference-in-differences strategy where the 2008 New York City Labeling Mandate serves as the exogenous shock. Our results show a 4.4 percent decline in maternal weight gain during pregnancy. Excessive weight gain (i.e. more than 15 kg) during pregnancy also decreases, especially among minorities and relatively younger mothers. We find statistically significant and economically meaningful declines in the prevalence of pregnancy-associated hypertension, post- term pregnancies and birth weight. The impact of information disclosure on maternal weight gain seems to translate into a decrease in the incidence of risk factors and complications during pregnancy and labor. We argue that providing expecting mothers with information and raising awareness about the consequences of their choices should be an integral part of maternal and child health policies.
