We formulate a collection of desirable properties for any sequential forecasting mechanism. We present a randomized mechanism that satisfies all of these properties, including a guarantee that it is myopically optimal for each agent to report honestly, regardless of her degree of risk aversion. We observe, however, that the mechanism has an undesirable side effect: each agent's expected reward, normalized against the inherent value of her private information, decreases exponentially with the number of agents. We prove a negative result showing that this is unavoidable: any mechanism that is myopically strategyproof for agents of all risk types, while also satisfying other natural properties of sequential forecasting mechanisms, must sometimes result in a player getting an exponentially small expected normalized reward.<\/jats:p>","DOI":"10.1145\/2716327","type":"journal-article","created":{"date-parts":[[2015,8,4]],"date-time":"2015-08-04T13:57:39Z","timestamp":1438696659000},"page":"1-23","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Subsidized Prediction Mechanisms for Risk-Averse Agents"],"prefix":"10.1145","volume":"3","author":[{"given":"Stanko","family":"Dimitrov","sequence":"first","affiliation":[{"name":"University of Waterloo"}]},{"given":"Rahul","family":"Sami","sequence":"additional","affiliation":[{"name":"University of Michigan (current affiliation: Google, Bangalore, India)"}]},{"given":"Marina A.","family":"Epelman","sequence":"additional","affiliation":[{"name":"University of Michigan"}]}],"member":"320","published-online":{"date-parts":[[2015,7,31]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/1566374.1566412"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1287\/mnsc.33.4.542"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1287\/isre.12.3.225.9712"},{"volume-title":"Handbook of Experimental Economics Results","author":"Berg Joyce","key":"e_1_2_1_4_1","unstructured":"Joyce Berg , Robert Forsythe , Forrest Nelson , and Thomas Rietz . 2008.
