%description
Tools to determine when collective marketing, aggregation, grading and
bulk input procurement through farmer producer organisations (FPOs) and
agricultural cooperatives improve member-farmer returns. The package
provides channel-level transaction cost accounting (transport,
commissions, market fees, time, rejection and payment-delay costs),
estimation of scale economies from consolidated transport, tiered bulk
input discounts and grading premiums, break-even throughput and
procurement-price analysis, and comparison of individual and collective
marketing scenarios. Its core is a member-level distributional accounting
framework that separates the total surplus generated by an FPO from the
benefits actually received by farmers through prices, transaction cost
savings, input savings and dividends, and summarises their distribution
across members with Gini and concentration indices and farm-size group
shares.
