Learning by observing: information spillovers in the execution and valuation of commercial bank M&As

We hypothesize that banks become better able to manage acquisitions, and investors become better able to value those acquisitions, as these parties ‘learn-by-observing’ information that spills-over from previous bank M&As. We find evidence consistent with these hypotheses for 216 M&As of large, publicly traded U.S. commercial banks between 1987 and 1999. Our theory and our results are predicated on the idea that acquisitions of large and increasingly complex commercial banks were a relatively new phenomenon in the late-1980s, with no best practices to inform bank managers and little information upon which investors could base their valuations. Our findings provide a new explanation for why academic studies have found little evidence that bank mergers create value. Furthermore, our finding that investors become more accurate pricers of new phenomena as they observe greater quantities of those phenomena is consistent with the theory of semi-strong stock market efficiency.Bank mergers ; Financial institutions

Banking Globalization: International Consolidation and Mergers in Banking

This paper surveys recent literature on international mergers and acquisitions in banking. We focus on three main questions. First, what are the determinants of cross-border mergers of commercial banks? Second, do cross-border mergers affect the efficiency of banks? Third, what are the risk effects of international bank mergers? We begin with a brief summary of the stylized facts, and we conclude with implications for policymakers.mergers and acquisition, international banking, survey

Issues in the Credit Risk Modeling of Retail Markets

Retail loan markets create special challenges for credit risk assessment. Borrowers tend to be informationally opaque and borrow relatively infrequently. Retail loans are illiquid and do not trade in secondary markets. For these reasons, historical credit databases are usually not available for retail loans. Moreover, even when data are available, retail loan values are small in absolute terms and therefore application of sophisticated modeling is usually not cost effective on an individual loan-by-loan basis. These features of retail lending have led to the development of techniques that rely on portfolio aggregation in order to measure retail credit risk exposure. BIS proposals for the Basel New Capital Accord differentiate portfolios of mortgage loans from revolving credit loan portfolios from other retail loan portfolios in assessing the bank’s minimum capital requirement. We survey the most recent BIS proposals for the credit risk measurement of retail credits in capital regulations. We also describe the recent trend away from relationship lending toward transactional lending, even in the small business loan arena traditionally characterized by small banks extending relationship loans to small businesses. These trends create the opportunity to adopt more analytical, data-based approaches to credit risk measurement. We survey proprietary credit scoring models (such as Fair, Isaac and SMEloan), as well as options-theoretic structural models (such as KMV and Moody’s RiskCalc) and reduced form models (such as Credit Risk Plus)
