遏制公共项目中的漏损:来自印度直接转移支付政策的证据

Curbing Leakage in Public Programs: Evidence from India’s Direct Benefit Transfer Policy
American Economic Review · 2024 · Prabhat Barnwal

中文摘要

定向价格补贴会在补贴价格与非补贴价格之间造成差距。由此产生的双重定价可能带来套利机会,使中间商通过黑市将补贴商品转用于非预期受益人。本文研究印度针对烹饪燃料补贴实施的直接转移支付政策,该政策通过将补贴直接转入受益人的银行账户,改变了原有的补贴计划。该政策减少了补贴燃料的购买量,表明流向黑市的转用有所减少。非补贴燃料销售和黑市价格的变化提供了支持性证据,表明漏损有所减少。这些结果表明,解决福利发放中潜在的逆向激励问题,可以通过遏制漏损来提高效率。(JEL D73、I38、O17、Q41、Q48)

Abstract

Targeted price subsidies create a gap between subsidized and unsubsidized prices. The resulting dual pricing can lead to arbitrage opportunities where intermediaries divert subsidized goods to unintended beneficiaries via the black market. I study India’s Direct Benefit Transfer policy for cooking fuel subsidies, which altered the existing subsidy program by transferring subsidies directly to beneficiaries’ bank accounts. The policy decreased subsidized fuel purchases, indicating a reduction in diversion to the black market. Changes in unsubsidized fuel sales and black market prices provide supporting evidence that leakage was reduced. These results suggest that addressing the underlying perverse incentives in welfare delivery can improve efficiency by curbing leakages. (JEL D73, I38, O17, Q41, Q48)
