Data and R code for "Farmer producer organizations and regulated markets in the economics of agricultural sustainability transitions"

This replication package supports a comparative study of farmer producer organization (FPO) membership and Agricultural Produce Market Committee (APMC) market engagement among potato farm enterprises in Hassan district, Karnataka, India. The cross-sectional data cover 100 enterprises, comprising 50 in each institutional group. Enterprise production and marketing accounts are linked to categorical observations on institutional services, production and postharvest practices, adoption, perceived economic viability, and difficulty of discontinuation. The package contains three files: dataset.csv contains 66 observed variables. variable_descriptions.xlsx documents variable codes, descriptions, measurement units, categorical values, and definitions of derived variables. analysis.R constructs derived variables and generates statistical results, tables, diagnostics, and figures. The analyses include Bayesian hierarchical multivariate probit models, linear and quantile regression, Shapley decomposition, Firth logistic regression, and data envelopment analysis. These examine institutional differences in adoption, economic performance, and perceived constraints on discontinuation within a microeconomic framework of sustainability transitions. To reproduce the analyses, extract the archive, install the packages listed in analysis.R, set the working directory to the extracted folder, and run source("analysis.R", encoding = "UTF-8").
