WhataretheprosandconsofRELATIONSHIPLENDING?
FIRMS’PERSPECTIVEl PROS
§ MITIGATES CREDITRATIONINGPHENOMENA:Easier access tothecreditmarket, inparticular foropaque firms (small, young,highlyinnovative firms) (ALOTOFPAPERSONTHIS)
§ FLEXIBILITY: Incaseofaidiosyncratic shocktothefirm (e.g.atemporary drop inits profitability/liquidity)banks may restructure theloan (e.g.longer maturity,lower cost ofcredit,…)(MANYPAPERSTOO)
§ CONFIDENTIALITY: Theinformationgathered bybanksisnotdisclosedtofirms’competitor (Yosha, 1995)anditmayencourageR&Dinvestments (Bhattacharya andChiesa, 1995)
l CONS§ HOLD-UP:banks gainaninformational advantage against other lenders
andthen may charge higher interest rates; theborrower isinformationally captured (classic references: Sharpe,1990;Rajan,1992;vonThadden,2004)

Relationship lending theories What are the benefits of relationship lending?
1. Risk-sharing (implicit insurance)
Berger and Udell (1992), Berlin and
Mester (1999) Buying insurance regarding future access to credit
2. Interim monitoring (moral hazard)
Holmstrom and Tirole, (1997)
Only firms that don't have a sufficient stake in the project ask for a monitored bank loan, while firms with sufficient cash (or collateral) will prefer arm's length financing (transactional loans). Relationship banks' recognize the firms' type and monitoring is simply a way to limit the moral hazard problem.
3. Ex-ante screening (adverse
selection)
Agarwal and Hauswald (2010), Puri et
al. (2010)
Relationship banks may be better able to ex-ante screen the firms. The comparative advantage for relationship banks lead to an ex-post monopoly of information.
4. Learning
Rajan (1992), von Tadden (1995),
this paper.
Relationship banks do not know the firm type at the beginning but can learn it by monitoring. Monitoring is costly and this is reflected in higher lending rates in good times. However, in bad times R-banks have a strong incentive to shield the clients in order not to waste the information investment (and the sunk cost sustained).
Maincharacteristicsofthetheoreticalmodel
Themodel(1)• Extension of Bolton and Freixas (2006), which consider firms'
choice of the optimal mix of financing between borrowing froma relationship bank (R-bank) and issuing a corporate bond.Two key modifications:
1. AllowforachoicebetweenborrowingfromanR-bankoraT-bank(oracombinationofthetwo,mixedfinance)
2. Introduceaggregatebusiness-cyclerisk,toallowfirmstodifferintheirexposuretothisrisk,andtoconsiderhowtheresponseofR-bankstoacrisisdiffersfromthatofT-banks
Themodel(2)• Mainingredientsofthetheoreticalmodel:
1. RvsTbanks.1. Thefirm’stypeisprivateinformation int=0.Int=1,onlyR-banks can
observe itperfectly afterhavingpaidsomemonitoring costs𝒎2. R-banks havehigher intermediation costs (𝜌# > 𝜌%)because theyhave
toholdmoreequitycapitalagainsttheexpectationofmorefuture rollover lending
2. BusinesscycleandFirms.1. Theproject succeedsorfailsdepending onaknownprobability𝑝 thatis
commonlyobserved.2. FirmscanbeoftwotypesH (highvalue)orL (lowvalue).

2. L-typefirmsarenotaffected bythestateoftheeconomy

Interestratesettingbybank’stypeandstateoftheworld
• The cost of credit of transactional lending is always lower than relationship banking in good times. This pattern is reversed in bad times. In line with the model, it is always cheaper for safe firms to use T-banks.
