DO NEIGHBORHOOD PARKS AND PLAYGROUNDS REDUCE CHILDHOOD OBESITY? AgEcon
Fan, Maoyong; Jin, Yanhong H..
Promoting physical activity in children is an important front battling Childhood obesity. This paper investigates if and by how much neighborhood parks and playgrounds, one of the most important activity-enhancing neighborhood facilities, affect childhood obesity. We employ a covariate matching technique to analyze the 2007 National Survey of Children Health data. We find that neighborhood parks and playgrounds make children more fit. The reduction in body mass index (BMI) as well as the overweight or obesity risk is both statistically and economically significant. We also find that the park impact depends on gender, age, race, income, neighborhood safety, and other neighborhood amenities. The results suggest that a provision of neighborhood parks and...

Balancing Grower Protection Against Agency Concerns: An Economic Analysis of Contract Termination Damages AgEcon
Lee, Myoungki; Wu, Steven Y.; Fan, Maoyong.
This study examines legislation that would grant growers termination damages if their contracts are terminated. Our model suggests that, with no contracting frictions, damages would not reduce ex ante efficiency as processors can contract around damages through contract restructuring. Growers would earn less under continuation but would be protected if terminated, although overall expected profits would be unaffected. However, when contracting friction exist, then efficiency losses can occur as processors would be constrained in restructuring contractual incentives to deal with moral hazard. Growers' expected profits would increase while processors' profit would decrease.

Balancing Grower Protection Against Agency Concerns: An Economic Analysis of Contract Termination Damages AgEcon
Fan, Maoyong; Lee, Myoungki; Wu, Steven Y..
Using a dynamic principal-agent model, we analyze termination damages that protect growers from contract termination or non-renewal. We show that government imposed breach damages can be distortionary and may not necessarily lead to increased grower welfare.
