Efficiency and Equity of Input Subsidies : Experimental Evidence from Tanzania

Input subsidy programs (ISP) often have two conflicting targeting goals: selecting individuals with the highest marginal return to inputs on efficiency grounds, or the poorest individuals on equity grounds, allowing for a secondary market to restore efficiency gains. To study this targeting dilemma,...

To study this targeting dilemma, we implement a field experiment where beneficiaries of an ISP were selected via a lottery or a local committee. In lottery villages, we find evidence of displacement of private fertilizer and of a secondary market as beneficiaries are more likely to sell inputs to non-beneficiaries. In contrast, in non-lottery villages we find no evidence of displacement nor of elite capture. The impacts of the ISP on agricultural productivity and welfare are limited, suggesting that resources should be directed at complementary investments, such as improving soil quality and irrigation. 2022-03-11T06:58:35Z 2022-03-11T06:58:35Z 2019-01-01 Journal Article American Journal of Agricultural Economics 1467-8276 http://hdl.handle.net/10986/37122 CC BY-NC-ND 3.0 IGO http://creativecommons.org/licenses/by-nc-nd/3.0/igo World Bank Washington, DC: World Bank Publications & Research :: Journal Article Tanzania
