Why Credit Booms Lead to Why Credit Booms Lead to CrisesCrises

““Financial acceleratorsFinancial accelerators”” (Kiyotaki and Moore, (Kiyotaki and Moore, JPE 1997): an increase in value of collateralizable JPE 1997): an increase in value of collateralizable goods releases credit constraints. Boom fuels goods releases credit constraints. Boom fuels further wealth effects etc. Negative shocks inverts further wealth effects etc. Negative shocks inverts cycle, leaving banking system overexposed cycle, leaving banking system overexposed

““Institutional memoryInstitutional memory”” (Berger and Udell, JFI (Berger and Udell, JFI 2004): in periods of fast credit expansion banks find 2004): in periods of fast credit expansion banks find it difficult to recruit enough experienced loan it difficult to recruit enough experienced loan officers (especially if there has not been a crisis for officers (especially if there has not been a crisis for a while). This leads to a deterioration of loan a while). This leads to a deterioration of loan portfoliosportfolios

““Informational capital and adverse selection”Informational capital and adverse selection” (Dell’Ariccia and Marquez, JF 2006): during (Dell’Ariccia and Marquez, JF 2006): during expansions, adverse selection is less severe and expansions, adverse selection is less severe and banks find it optimal to trade quality for market banks find it optimal to trade quality for market share, increasing crisis probabilityshare, increasing crisis probability
