SUMMARY:Brown Bag Seminar: Prabhat Barnwal
DESCRIPTION:PSC’s Brown Bag seminar series typically convenes Mondays at noon, at ISR Thompson Room 1430, and on Zoom.Prabhat Barnwal from Michigan State joins us Sept. 22, 2025.Commitment, social enforcement and limits to formalizing informal risk-sharingAbstract: We study the role of commitment and social enforcement in risk sharing among households. We design a novel experiment to study how ex-ante commitments can help enhance risk pooling to mitigate idiosyncratic shocks, using the context of arsenic poisoning of groundwater in Bangladesh. In a field experiment con- ducted across 135 village communities in rural Bangladesh, we evaluate the impact of facilitating ex-ante commitments between household pairs to share safe water using a randomized controlled trial. In addition to the base treatment, we further add two treatments arms that include a notification to households about peer monitoring on these commitments, and the actual implementation of this monitoring, before and after arsenic testing. We document three main results. First, awareness of monitoring enhances rural households’ positive assortative matching in risk-sharing partners. Second, facilitating commitment moderately reduces arsenic consumption. Third, peer monitoring counteracts the effect of ex-ante commitments. We find these results are likely driven by several norm and behavior-based channels. Our findings imply the complexity of facilitating risk-sharing behaviors in the presence of norms and social incentives.Bio: Prof. Prabhat Barnwal is an Associate Professor of Economics at Michigan State University. His research lies at the intersection of development, environmental, and public economics, with a focus on how policies and technologies shape welfare outcomes in low- and middle-income countries. Much of his work uses large-scale field experiments and administrative data from South Asia to study issues such as energy subsidies, environmental quality, and household welfare.  He is visiting the University of Michigan during Fall 2025.https://umich.zoom.us/j/95418610585?pwd=Z0cvdkF1T0R2cG1lRDEvVmlnbVdlZz09Meeting ID: 954 1861 0585\nPasscode: 818420\nOne tap mobile\n+13017158592,,95418610585# US (Washington DC)\n+13092053325,,95418610585# USDial by your location\n+1 301 715 8592 US (Washington DC)\n+1 309 205 3325 US\n+1 312 626 6799 US (Chicago)\n+1 646 876 9923 US (New York)\n+1 646 931 3860 US\n+1 564 217 2000 US\n+1 669 444 9171 US\n+1 669 900 6833 US (San Jose)\n+1 719 359 4580 US\n+1 253 215 8782 US (Tacoma)\n+1 346 248 7799 US (Houston)\n+1 386 347 5053 US\n+1 647 374 4685 Canada\n+1 647 558 0588 Canada\n+1 778 907 2071 Canada\n+1 780 666 0144 Canada\n+1 204 272 7920 Canada\n+1 438 809 7799 Canada\n+1 587 328 1099 Canada\nMeeting ID: 954 1861 0585\nFind your local number: https://umich.zoom.us/u/aCRAyuQaTJoin by SIP\n95418610585@zoomcrc.comJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (Amsterdam Netherlands)\n213.244.140.110 (Germany)\n103.122.166.55 (Australia Sydney)\n103.122.167.55 (Australia Melbourne)\n149.137.40.110 (Singapore)\n64.211.144.160 (Brazil)\n149.137.68.253 (Mexico)\n69.174.57.160 (Canada Toronto)\n65.39.152.160 (Canada Vancouver)\n207.226.132.110 (Japan Tokyo)\n149.137.24.110 (Japan Osaka)\nMeeting ID: 954 1861 0585\nPasscode: 818420 \n
