Abstract
Bank efficiency estimates often serve as a proxy of managerial skill since they quantify sub-optimal production choices. But such deviations can also be due to omitted systematic differences among banks. In this study, we examine the effects of heterogeneity on bank efficiency scores. We compare different specifications of a stochastic cost and alternative profit frontier model with a baseline specification. After conducting a specification test, we discuss heterogeneity effects on efficiency levels, ranks and the tails of the efficiency distribution. We find that heterogeneity controls influence both banks’ optimal costs and profits and their ability to be efficient. Differences in efficiency scores are important for more than only methodological reasons. First, different ways of accounting for heterogeneity result in estimates of foregone profits and additional costs that are significantly different from what we infer from our general specification. Second, banks are significantly re-ranked when their efficiency is estimated with a specification other than the preferred, general specification. Third, the general specification gives the most reliable estimates of the probability of distress, although differences to the other specifications are low.

Securitization and the Declining Impact of Bank Finance on Loan Supply: Evidence from Mortgage Originations
Elena Loutskina, Philip E. Strahan
Journal of Finance,
No. 2,
2009
Abstract
Low‐cost deposits and increased balance sheet liquidity raise banks' supply of illiquid loans more than loans easily sold or securitized. We exploit the inability of Fannie Mae and Freddie Mac to purchase jumbo mortgages to identify an exogenous change in liquidity. The volume of jumbo mortgage originations relative to nonjumbo originations increases with bank holdings of liquid assets and decreases with bank deposit costs. This result suggests that the increasing depth of the mortgage secondary market fostered by securitization has reduced the effect of lender's financial condition on credit supply.

The Impact of Organizational Structure and Lending Technology on Banking Competition
Hans Degryse, Luc Laeven, Steven Ongena
Review of Finance,
No. 2,
2009
Abstract
We investigate how bank organization shapes banking competition. We show that a bank's geographical lending reach and loan pricing strategy is determined by its own and its rivals’ organizational structure. We estimate the impact of organization on the geographical reach and loan pricing of a large bank. We find that the reach of the bank is smaller when rival banks are large and hierarchically organized, have superior communication technology, have a narrower span of organization, and are closer to a decision unit with lending authority. Rival banks’ size and the number of layers to a decision unit soften spatial pricing.

Bank Regulation and Supervision in Bank-dominated Financial Systems: A Comparison between Japan and Germany
Diemo Dietrich, Ralf Bebenroth, Uwe Vollmer
European Journal of Law and Economics,
2009
Abstract
Diese Arbeit vergleicht die Bankenregulierung und -aufsicht in Japan und Deutschland. Diese Länder werden betrachtet, weil sie beide ein bankendominiertes Finanzsystem aufweisen und trotzdem Unterschiede in Bezug auf die Bankenstabilität aufweisen. Es wird gezeigt, dass Japan und Deutschland unterschiedliche Ansätze zur Regulierung und Aufsicht von Banken gewählt haben, und fragt, warum sie ihre Wahl so getroffen haben. Es wird argumentiert, dass Regulierung und Aufsicht in Japan weniger effizient gewesen sind und dass diese Unterschiede maßgeblich für das verschiedene Bankenverhalten war.

Why Do Payday Lenders Enter Local Markets? Evidence from Oregon
H. Evren Damar
Review of Industrial Organization,
No. 2,
2009
Abstract
This study analyzes payday lenders’ entry strategies in the state of Oregon in order to look for changes in the nature of the industry and its relationship to traditional financial institutions. The results of fixed-effects logit regressions suggest that payday lenders have started to enter areas already being served by banks. Furthermore, the presence of “incumbent advantage” in entry decisions may also have implications concerning the level of competition in the industry. Finally, since payday lenders also enter areas with large Hispanic populations, it is still possible that payday loans represent the sole source of credit for certain segments of the population.

Stages of the 2007/2008 Global Financial Crisis: Is there a Wandering Asset Price Bubble?
Lucjan T. Orlowski
Economics E-Journal 43. Munich Personal RePEc Archive 2008,
2009
Abstract
This study identifies five distinctive stages of the current global financial crisis: the meltdown of the subprime mortgage market; spillovers into broader credit market; the liquidity crisis epitomized by the fallout of Northern Rock, Bear Stearns and Lehman Brothers with counterparty risk effects on other financial institutions; the commodity price bubble, and the ultimate demise of investment banking in the U.S. The study argues that the severity of the crisis is influenced strongly by changeable allocations of global savings coupled with excessive credit creation, which lead to over-pricing of varied types of assets. The study calls such process a “wandering asset-price bubble“. Unstable allocations elevate market, credit, and liquidity risks. Monetary policy responses aimed at stabilizing financial markets are proposed.

Cross-Border Bank Contagion in Europe
Reint E. Gropp, M. Lo Duca, Jukka M. Vesala
International Journal of Central Banking,
No. 1,
2009
Abstract
We analyze cross-border contagion among European banks in the period from January 1994 to January 2003. We use a multinomial logit model to estimate, in a given country, the number of banks that experience a large shock on the same day (“coexceedances”) as a function of common shocks and lagged coexceedances in other countries. Large shocks are measured by the bottom 95th percentile of the distribution of the daily percentage change in distance to default of banks.We find evidence of significant cross-border contagion among large European banks, which is consistent with a tiered cross-border interbank structure. The results also suggest that contagion increased after the introduction of the euro.

Banking Integration, Bank Stability, and Regulation: Introduction to a Special Issue of the International Journal of Central Banking
Reint E. Gropp, H. Shin
International Journal of Central Banking,
No. 1,
2009
Abstract
The link between banking integration and financial stability has taken center stage in the wake of the current financial crisis. To what extent is the banking system in Europe integrated? What role has the introduction of the common currency played in this context? Are integrated banking markets more vulnerable to contagion and financial instability? Does the fragmented regulatory framework in Europe pose special problems in resolving bank failures? What policy reforms may become necessary? These questions are of considerable policy interest as evidenced by the extensive discussions surrounding the design and implementation of a new regulatory regime and by the increasing attention coming from academia.

A Lesson Learned? Pre- and Post-Crisis Entry Decisions in Turkish Banking
H. Evren Damar
Contemporary Economic Policy,
No. 1,
2009
Abstract
This study looks at the determinants of entry by Turkish banks into local markets during the periods before and after the crisis of 2000–2001. Motivated by a theoretical model of entry, results of fixed-effects logit regressions suggest that there has been a change in the geographical diversification strategies of Turkish banks. It appears that the dominance of strategic concerns, such as competing with banks of similar size, has diminished, while economic concerns, such as incumbent characteristics and cost considerations, have become more important. Overall, the postcrisis restructuring policies seem to have led to improved decision making in the sector.

Contestability, Technology and Banking
S. Corvoisier, Reint E. Gropp
ZEW Discussion Papers, No. 09-007,
No. 7,
2009
Abstract
We estimate the effect of internet penetration on retail bank margins in the euro area. Based on an adapted Baumol [1982] type contestability model, we argue that the internet has reduced sunk costs and therefore increased contestability in retail banking. We test this conjecture by estimating the model using semi-aggregated data for a panel of euro area countries. We utilise time series and cross-sectional variation in internet penetration. We find support for an increase in contestability in deposit markets, and no effect for loan markets. The paper suggests that for time and savings deposits, the presence of brick and mortar bank branches may no longer be of first order importance for the assessment of the competitive structure of the market.
