There is no impact on consumer demand under the money-back guarantee, but demand increases under a third-party certification or warranty, which is consistent with the notion that consumers are uncertain about products\u2019 durability rather than their utility. Surprisingly, these efforts to overcome an information asymmetry problem stimulate demand for low-quality products by creating product-class effects among those least familiar with the product","geographic_units":[{"name":"Senegal","code":"SEN","type":"Country"}],"keywords":[{"name":"Information Asymmetries"},{"name":"Quality Signaling"},{"name":"Solar Lamps"},{"name":"Willingness To Pay"},{"name":"Becker-Degroot-Marschak"}],"topics":[{"id":"D12","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Consumer Economics: Empirical Analysis","parent_id":"D1"},{"id":" D83","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Search \u2022 Learning \u2022 Information and Knowledge \u2022 Communication \u2022 Belief \u2022 Unawareness","parent_id":"D8"},{"id":" L15","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Information and Product Quality \u2022 Standardization and Compatibility","parent_id":"L1"},{"id":" O13","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Agriculture \u2022 Natural Resources \u2022 Energy \u2022 Environment \u2022 Other Primary Products","parent_id":"O1"},{"id":" Q41","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Demand and Supply \u2022 Prices","parent_id":"Q4"}],"output":[{"type":"Working Paper","description":"Policy Research Working Papers (PRWP)","title":"Quality Signaling And Demand For Renewable Energy Technology: Evidence From A Randomized Field Experiment"}],"language":[{"name":"English","code":"EN"}],"disclaimer":"The materials in the reproducibility packages are distributed as they were prepared by the staff of the International Bank for Reconstruction and Development\/The World Bank.
