A Theory of Predaton Based on Agency Problems n Fnancal Contractng Patrck Bolton, Davd S. Scharfsten The Amercan Economc evew, Volume 80, Issue Mar., 990, 93-06. Presented by Tatana Levna
The Borrower-Lender elatonshp When a bank grants a loan to a borrower, both partes typcally sgn a contract Bolton and Scharfsten study a repeated borrower-lender relatonshp n whch the threat of termnaton by the lender provdes ncentves for the borrower to repay the loan. Ths termnaton threat, however, s costly n a compettve envronment. Theory of Bankng and Fnancal Intermedaton

Unobservable Contracts When contracts are unobservable, t s as f the nvestor and the predator play a smultaneous move game.

Concluson The central argument of ths paper s that agency problems n fnancal contractng can gve rse to ratonal predaton. The fnancal contract that mnmzes agency problems also maxmzes rvals ncentves to prey. Theory of Bankng and Fnancal Intermedaton
Appendx Postve proft condton n Proposton : Gven the optmal contract, the nvestor expected profts are: θ F θ F F = F θ F > 0 Thus F < / θ Theory of Bankng and Fnancal Intermedaton
Appendx Proposton : there s an ex post neffcency; the frm s lqudated when frst-perod proft s even though > F and t s effcent to operate. Predaton can nduce lqudaton and ext because t adversely affects the agency relatonshp between the rval s nvestors and manager. Ths may force the frm to rely more on nternal sources of captal than on external ones. But, ths reduces the extent to whch outsde nvestors montor the frm and ncreases the possblty of manageral slack.
