The distributional effects of contractual norms: the case of cropshare agreements
According to principal-agent theory, a share contract strikes an optimal balance between risk-sharing and incentive provision when it is difficult to gauge the agent's contribution. This theory predicts that the size of the share should vary with economic fundamentals. In practice, however, the share divisions that are specified often cluster around "usual and customary" levels ? even when there is substantial heterogeneity among principal - agent pairs. Using Illinois farm-level data observed between 1980 and 1994 that include soil productivity ratings, tenant net income, and crop yields, ...

Did the Affordable Care Act Affect Access to Medications for Opioid Use Disorder among the Already Insured? Evidence from the Rhode Island All-payer Claims Database
Previous research suggests that state Medicaid expansions implemented under the Patient Protection and Affordable Care Act (ACA) helped large numbers of patients suffering from opioid use disorder (OUD) gain access to life-saving medications, including buprenorphine. However, Medicaid expansions could have impeded access to care among individuals already enrolled in Medicaid, as new enrollees would have placed added demands on a limited supply of buprenorphine providers. Using a panel data set of medical claims from Rhode Island, we estimate the causal effects of the state’s January 2014 ...

Medication-assisted Treatment for Opioid Use Disorder in Rhode Island: Who Gets Treatment, and Does Treatment Improve Health Outcomes?
Since the early 2000s Rhode Island has been among the states hardest hit by the opioid crisis. In response, the state has made it a priority to expand access to medication-assisted treatment (MAT) for opioid use disorder (OUD), which refers to the use of the FDA-approved medications methadone, buprenorphine, and/or naltrexone in conjunction with behavioral therapy. MAT is strongly supported by scientific evidence and endorsed by US public health officials and yet fails to reach many OUD patients. Using administrative data covering medical treatments and selected health outcomes for more than ...

Community Education Circles in the Lawrence Public Schools: evaluation design and baseline survey data
This paper describes a plan for evaluating the Community Education Circles (CECs) program that is being implemented in the Lawrence Public Schools as part of an effort to enhance family-school engagement and improve outcomes for both students and parents. The CECs program supports the larger Lawrence Working Families Initiative, which in 2013 was awarded a multiyear grant through the Boston Fed?s Working Cities Challenge. This paper accomplishes several objectives: (1) describe the goals and methods of the CECs program as well as the larger goals of the Lawrence Working Families Initiative; ...

Classroom peer effects and student achievement
In this paper we analyze the impact of classroom peers on individual student performance with a unique longitudinal data set covering all Florida public school students in grades 3-10 over a five-year period. Unlike many previous data sets used to study peer effects in education, our data set allow us to identify each member of a given student?s classroom peer group in elementary, middle, and high school as well as the classroom teacher responsible for instruction. As a result, we can control for individual student fixed effects simultaneously with individual teacher fixed effects, thereby ...

Classroom peer effects and student achievement
In this paper we analyze the impact of classroom peers' ability on individual student achievement with a unique longitudinal data set covering all Florida public school students in grades 3-10 over a five-year period. Unlike many data sets used to study peer effects in education, ours identifies each member of a student's classroom peer group in elementary, middle, and high school as well as the classroom teacher responsible for instruction. As a result, we can control for student fixed effects simultaneously with teacher fixed effects, thereby alleviating biases due to endogenous assignment ...
Using Inflation Expectations to Boost Consumer Spending Poses Policy Risks
Communication that raises inflation expectations has been suggested as a policy tool for central banks. Our research suggests that this policy tool has some limitations that central banks must manage when implementing it.

Informal work in the United States: evidence from survey responses
"Informal" work refers to temporary or occasional side jobs from which earnings are presumably not reported in full to the Internal Revenue Service and which typically do not constitute a dominant or complete source of income. Perhaps the most important reason for undertaking informal work is to offset negative income and employment shocks, such as reduced hours in a formal job, stagnant wages, or involuntary unemployment. Such negative shocks affected many Americans during the Great Recession, so it is important to determine the extent to which people engaged in informal work during this ...

Has overweight become the new normal?: evidence of a generational shift in body weight norms
We test for differences across the two most recent NHANES survey periods (1988?1994 and 1999?2004) in self-perception of weight status. We find that the probability of self-classifying as overweight is significantly lower on average in the more recent survey, for both men and women, controlling for objective weight status and other factors. Among women, the decline in the tendency to self-classify as overweight is concentrated in the 17?35 age range, and, within this range, is more pronounced among women with normal BMI than among those with overweight BMI. Among men, the shift away from ...

Explaining gender-specific racial differences in obesity using biased self-reports of food intake
Policymakers have an interest in identifying the differences in behavior patterns - namely, habitual caloric intake and physical activity levels - that contribute to demographic variation in body mass index (BMI) and obesity risk. While disparities in mean BMI and obesity rates between whites (non-Hispanic) and African-Americans (non-Hispanic) are well-documented, the behavioral differences that underlie these gaps have not been carefully identified. Moreover, the female-specificity of the black-white obesity gap has received relatively little attention. In the National Health and Nutrition ...
