Gregory Howard, AEDE Ph.D. candidate in the Department of Agricultural, Environmental, and Development Economics (AEDE) at The Ohio State University, will present as part of the AEDE Seminar Series on November 19th* in Room 105 of the Agricultural Administration Building (2120 Fyffe Road).  His presentation will focus on "A Latent Class Analysis of Farmer Preferences Regarding Filter Strip Programs", which is based on research that he co-authored with Brian Roe, AEDE Professor.

Abstract: Using responses from a survey of Ohio farmers, we utilize conjoint analysis and examine to what extent farmer preferences over filter strip programs are influenced by 1) various program attributes, and 2) farmer perceptions of the efficacy of filter strips in preventing runoff. We adopt a two-stage estimation method to control for endogeneity of the efficacy measure using exogenous field attributes and exogenously assigned filter strip size as instruments. We additionally utilize latent class analysis in both the first and second stage, allowing for discrete preference heterogeneity among farmers. I use two models in the second stage, an order logistic regression for which the dependent variable is program ranking and a conditional logistic regression for which the dependent variable is an indicator variable for whether the program was considered the best.

This event is open to the public and no RSVP is required.  If you have any questions, please contact us
