Research shows that audit fees have increased after the SOX ban on providing non-audit services (NAS) to audit clients, but the reasons behind it have been unclear. Using an auction-modeling approach, this study aims to bridge this gap by providing a theoretical explanation for this empirical...

The literature shows that audit fees have increased after the SOX ban to audit clients on non-audit services (NAS) but the reason behind it has been unclear until now. Using an auction modeling approach, this study aims to bridge this gap by providing a theoretical explanation for this enigma....

We study an asymmetric all-pay auction with a general utility function. We show that high-type bidders in all-pay auction with lower density, are bidding more aggressively than bidders with higher density. This result is contradictory to the result in Parreiras and Rubinchik (2010) on aggressive...

We study asymmetric first-price auctions with n bidders. We expand the results of Fibich et al. (2002) for asymmetric first-price auctions to a general utility function. We show that for low type bidders, the equality of equilibrium bids with symmetric, uniform distribution bids holds for the...

We study the effect of prebidding and postbidding in first-price auctions with a single prize under incomplete information. All the bidders' values are private information except bidder 1's value which is commonly known. Bidder 1 places his bid either before (prebidding auction) or after...

We use perturbation analysis to study independent private-value all-pay auctions with weakly risk-averse buyers. We show that under weak risk aversion: 1) Buyers with low values bid lower and buyers with high values bid higher than they would bid in the risk neutral case. 2) Buyers with low...

This paper examines contracting between a venture capitalist and an entrepreneur in a setting with unobservable effort when contracts are renegotiated each period. The contribution of our paper lies in the insights it provides on optimal contracts in this setting. The insights from our model...
