July 2020Expanding Access to Clean Water for the Rural Poor: Experimental Evidence from Malawi
with Pascaline Dupas, Basimenye Nhlema, Aaron Wolf, Emily Wroe: w27570
Using data from an 18-month randomized trial, we estimate large and sustained impacts on water purification and child health of a program providing monthly coupons for free water treatment solution (diluted chlorine) to households with young children. The program is more effective and much more cost-effective than asking Community Health Workers (CHWs) to distribute free chlorine to households during routine monthly visits. That is because only 40% of households make use of free chlorine, targeting through CHWs is worse than self-targeting through coupon redemption, and water treatment promotion by CHWs does not increase chlorine use among free chlorine beneficiaries. Non- use of free chlorine is driven by households who have a protected water source and those who report that chlorine make...
November 2019Does The Market Reward Quality?: Evidence from India
with Somalee Banerjee, Manoj Mohanan, Neeraj Sood: w26460
There are two salient facts about health care in low and middle-income countries; 1) the private sector plays an important role and 2) the care provided is often of poor quality. Despite these facts we know little about what drives quality of care in the private sector and why patients continue to seek care from poor quality providers. We use two field studies in India that provide unique insight into this issue. First, we use a discrete choice experiment to show that patients are willing to pay higher prices for better technical quality (defined by correct treatment and correct diagnosis). Second, we use standardized patients to show that private providers who provide better technical quality are not able to charge higher prices. Instead providers are able to charge higher prices for elem...
February 2015Patient Responses to Incentives in Consumer-directed Health Plans: Evidence from Pharmaceuticals
with Peter J. Huckfeldt, Amelia Haviland, Ateev Mehrotra, Neeraj Sood: w20927
Prior studies suggest that consumer-directed health plans (CDHPs) -characterized by high deductibles and health care accounts- reduce health costs, but there is concern that enrollees indiscriminately reduce use of low-value services (e.g., unnecessary emergency department use) and high-value services (e.g., preventive care). We investigate how CDHP enrollees change use of pharmaceuticals for chronic diseases. We compare two large firms where nearly all employees were switched to CDHPs to firms with conventional health insurance plans. In the first firm’s CDHP, pharmaceuticals were subject to the deductible, while in the second firm pharmaceuticals were exempt. Employees in the first firm shifted the timing of drug purchases to periods with lower cost sharing and were more likely to use lo...
