Charles T.Carlstrom  \nContagious bank falures re ofenthought to be a possible conse-quence of a banking system withoutfederal deposit insurance.This articleconsiders whether federal depositinsurance is necessary to preventthese types of bank runs.  \nPart I,which was presented in the Feb-ruary 1 Economic Commentary,de-scribed some of the costs and benefitsof providing deposit insurance andconcluded that an analysis of conta-gious bank failures is necessary inorder to understand these benefits.  \nPart ll continues with an examinationof contagious bank runs and a discus·sion of how the market handled bank-ing panics prior to the FederalReserve System and the Federal De-posit Insurance Corporation.  \n■ Contagious Bank FailuresThe last apparent difference betweenbanks and other businesses is the pos-sibility for a rumor or a failure ofanother bank to ignite bank runs andcause the failure of financially soundbanks.  \nThese types of bank failures are termed\"sunspots\"because,if depositors trulybelieve that a bank's solvency dependson events unrelated to market funda-  \nBank Runs,Deposit Insurance,and Bank Regulation,Part II  \nmentals—such as the amount of solaractivity—a bank's solvency would,infact,depend on the amount of solaractivity.In the typical example,asunspot is the failure of one bank or agroup of banks,which ignites rumorsthat other banks might also fail  \nIt would seem irrational for depositors to run on a solvent bank.How.ever,because a bank's liquidity andsolvency depend in part on the num-ber of depositors wishing to withdrawmoney,it is rational for each deposi-tor to queue up if he expects otherdepositors also to stand on line.  \nSunspot bank runs are also said to be\"bubble\"phenomena.One of themost famous examples of a bubbleinvolved tulip bulbs in Holland dur-ing the seventeenth century.Investorsfrantically bought tulip bulbs,expect-ing their price to rise,which in turncaused their price to rise.2  \nSunspot bank runs are like bubbles inthat they are self-fulfilling prophecies.To determine the correct regulatoryresponse to this apparent market fail-ure,one must first inquire empiricallyhow frequently bank failures arecaused by sunspots and then ask whatis special about banking that allowsthese types of phenomena to arise.  \nFebruary 15,1988  \nPart I of this article,presented in theFebruary 1 Economic Commentary,described some of the costs andbenefits of providing federal depositinsurance.The major benefit of pro-viding deposit insurance is the pre-vention of contagious bank runs-abank failure that spreads to solventbanks.Part II,presented here,dis-cusses why bank runs may be conta-gious and examines some of theways in which private clearinghousesprotected against widespread bankfailures.The article concludes thatfederally provided deposit insurancemay not be necessary in order toprotect against such bank runs.  \nDetermining how often bank runs arecaused by sunspots—extraneousevents—is difficult to do with any degree of statistical accuracy.However,we can examine whether bank failureswere the products of the same type ofdeposit and withdrawal behavior dur-ing both panics and nonpanics  \nGorton tests this hypothesis for bankfailures during the U.S.National Bank-ing Era(1863 to 1914)and showsthat the factors affecting deposits andwithdrawals were similar in periodsof widespread bank failures and inperiods when banking failures werenot widespread.His results suggestthat \"banking panics during theNational Banking Era were systematicresponses by depositors to changingperceptions of risk.\"  \nCorroborating evidence that extrane-ous events did not seem to cause asubstantial number ofbank failuresprior to the Great Depression is givenby Benston,et al.They show that theaverage annual rate of bank failuresfor the 1875 to 1919 period was 0.82percent,versus 1.01 percent for non-financial firms.If banks are likeother firms except for the possibilityof contagious bank runs,one wouldexpect the failure rate of banks to beat least as ","cbCaidU5N1gib1A1","https://ap.wps.com/l/cbCaidU5N1gib1A1","pdf",1112591,"English","# Contagious Bank
