betweensocialunrestandGDP(Hadzi-Vaskovetal.,2023)andsocialunrestandstockprices(Barrettetal.,2022b),wefindthattheeffectofsocialunrestonunderpricingisalsosensitivetoinstitutionalquality.Specifically,wefindthatthenegativeassociationbetweenunrestandunderpricingisweakerinplacesthatscorebetteralongthefollowingdimensions:controlofcorruption,governmenteffectiveness,politicalstability,regulatoryquality,ruleoflaw,andvoiceandaccountability.LikeSchmeling(2009),whostudiesinvestorsentimentandaggregatestockmarketreturns,weinterpretthisasevidencethathigh-qualityinstitutionsweakentheassociation
