This study examines 1,009 articles published in the Journal of Agricultural and Resource Economics (JARE) from 1992 to 2024. It identifies 24 research topics using Latent Dirichlet Allocation and explores how topics and author collaboration networks influence citations. Article citation data from Scopus show that consumer, farm resource, and crop insurance articles lead overall and yearly citation growth. Niche topics demonstrate high citation intensity. A count regression finds that topic choice and certain types of author collaboration significantly predict citation counts. The findings underscore JARE’s scholarly influence and highlight its importance as a journal for disseminating impactful research in agricultural and resource economics.
This study evaluates the impact of groundwater restrictions under Kansas’s Local Enhanced Management Area program, focusing on the Sheridan-6 (SD6) region from 2013 to 2023. Using difference-in-differences regressions and well-level panel data, we find that SD6 irrigators reduced water use intensity by 16 percent and pumping costs by $5.48 per acre on average. No significant changes in irrigated acreage occurred. Differences from the control group decreased after 2018 when irrigators outside SD6 adopted less stringent water use policies. Results suggest that locally governed, farmer-led restrictions can reduce water use without diminishing productivity, though policy diffusion and adaptive responses complicate long-term measurement of conservation outcomes.
