agriEquity: Equity and Sustainability Assessment of Agricultural Subsidies
An integrated framework for evaluating whether agricultural
support measures reach smallholders, women farmers and resource-poor
regions, and at what productivity and environmental cost. It provides
survey-weighted benefit incidence analysis by landholding class, gender,
region or income quantile; concentration, Kakwani and Reynolds-Smolensky
progressivity measures (Kakwani, 1977) <doi:10.2307/2230485> with
bootstrap confidence intervals; multi-dimensional equity scorecards with
parity ratios and Theil decomposition of benefit inequality; effects of
subsidies on income inequality and Foster-Greer-Thorbecke poverty
(Foster, Greer and Thorbecke, 1984) <doi:10.2307/1913475>;
budget-neutral reallocation of a subsidy budget under alternative
allocation rules, including a welfare-optimal allocation that combines
diminishing productivity returns, Atkinson (1970)
<doi:10.1016/0022-0531(70)90039-6> inequality aversion and
environmental damage costs; and productivity-equity-sustainability
trade-off frontiers. Simulated farm-household data illustrate the
workflow.
