Edwige Cheynel’s research interests include financial disclosure, auditing and managerial accounting with a focus on analytical models. Particularly she studies the relation between firms’ voluntary disclosures and their expected market returns and the effects of such voluntary disclosures at the aggregate level, on the average cost of capital in the economy and the economic efficiency. In another paper, she studies the optimal pricing and distribution of financial analysts’ private information and the impacts on price efficiency. In her paper on auditing she analyzes the impact on audit effort, audit opinions, and audit informativeness of shifting from a regime in which audit report withdrawals are not public (previous practice) to one in which auditor withdrawals are disclosed by auditors to investors (PCAOB Release No. 2008-004). Prior to joining the PhD program, Edwige completed her Ph.D. in Business Administration at Carnegie Mellon University, Pittsburgh in fall 2009. Prior to joining the Ph.D. program, she obtained a master in Finance from HEC (Hautes Etudes Commerciales) in Paris and worked for Deloitte in the financial services.
