Size‐based regulation and water quality: Evidence from the Iowa hog industry

American Journal of Agricultural Economics, EarlyView.
Abstract The growing prevalence of animal feeding operations (AFOs) in the United States raises concerns among the public and regulators about their impact on local environmental quality. By linking historical regulatory records of AFOs in Iowa to downstream surface water pollution monitors, this paper studies the effects of the 2003 Clean Water Act ...

Optimal timing and rate of nitrogen fertilizer use: An integrated network technology approach

American Journal of Agricultural Economics, EarlyView.
Abstract Both the rate and timing of crop fertilizer application play an important role in agricultural productivity. However, inefficient fertilizer use can significantly increase production costs, water pollution, and greenhouse gas emissions. To capture both the spatial heterogeneity and dynamic nature of this problem, we develop a multi‐stage ...

Beyond health protection: Estimating the impact of public health insurance on home‐based livestock raising in rural China

American Journal of Agricultural Economics, EarlyView.
Abstract Livestock often serves as self‐insurance against health shocks for rural households in developing countries. However, little is known about how public health insurance affects livestock production decisions. This paper fills the gap by examining the impact of China's New Rural Cooperative Medical Scheme (NRCMS) on household‐level livestock ...

Information flow and the adoption of soil‐improving and water conservation measures, and household welfare: Insights from a randomized controlled trial in Uganda

American Journal of Agricultural Economics, EarlyView.
Abstract Extension services are designed to facilitate the flow of information from researchers to farmers. However, information failures continue to impede the diffusion of soil‐improving and water conservation technologies in Sub‐Saharan African countries. We use a randomized controlled trial (RCT) to examine the impact of an extension‐based campaign
