Targeting with In-Kind Transfers: Evidence from Medicaid Home Care

American Economic Review 2019 109(4), 1461-1485 open access
Making a transfer in kind reduces its value to recipients but can improve targeting. We develop an approach to quantifying this tradeoff and apply it to home care. Using randomized experiments by Medicaid, we find that in-kind provision significantly reduces the value of the transfer to recipients while targeting a small fraction of the eligible population that is sicker and has fewer informal care-givers than the average eligible. Under a wide range of assumptions within a standard model, the targeting benefit exceeds the distortion cost. This highlights an important cost of recent reforms toward more flexible benefits.

Corruption as a Local Advantage: Evidence from the Indigenization of Nigerian Oil

American Economic Review 2025 115(3), 1019-1057
Multinationals in the extractive sectors of weak states face resource theft by armed groups. Criminality is often abetted by state corruption, even though firms are willing to pay for protection. I study indigenization in Nigeria’s oil sector, which increased local firms’ participation substantially. Despite lower quality, local firms increase output by reducing oil theft. A bargaining model illustrates that political connections align law enforcement incentives, solving commitment problems. Data on law enforcement raids show that local firms receive preferential protection. Connections to military elites drive the local advantage. The aggregate gains from indigenization are at most between 2.3 and 5.7 percent of GDP.

Incidental Bequests and the Choice to Self-Insure Late-Life Risks

American Economic Review 2018 108(9), 2513-2550 open access
Despite facing significant uncertainty about their lifespans and health care costs, most retirees do not buy annuities or long-term care insurance. In this paper, I find that retirees’ saving and insurance choices are highly inconsistent with standard life-cycle models in which people care only about their own consumption but match well models in which bequests are luxury goods. Bequest motives tend to reduce the value of insurance by reducing the opportunity cost of precautionary saving. The results suggest that bequest motives significantly increase saving and significantly decrease purchases of long-term care insurance and annuities.

An Efficient Ascending-Bid Auction for Multiple Objects: Reply

American Economic Review 2018 108(2), 561-563
In a comment, Okamoto (2018 ) identifies and corrects a misspecification of the rationing rule in Ausubel (2004 ). This reply elaborates on the observation that the optimality of truthful bidding in dynamic auctions may be sensitive to the fine details of the rationing rule. It then discusses the wider role of sequential bid processing in restoring truthful bidding.

The Effects of Double-Blind versus Single-Blind Reviewing: Experimental Evidence from The American Economic Review

American Economic Review 2016
The results from a randomized experiment conducted at the American Economic Review on the effects of double-blind versus single-blind peer reviewing on acceptance rates and referee rating indicate that acceptance rates are lower and referees are more critical when the reviewer is unaware of the author's identity. These patterns are not significantly different between female and male authors. Authors at top-ranked universities and at colleges and low-ranked universities are largely unaffected by the different reviewing practices, but the authors at near-top-ranked universities and at nonacademic institutions have lower acceptance rates under double-blind reviewing.
