Abstract
Die im Rentenversicherungsbericht 2020 vorgelegten Projektionen der Rentenanpassungen der kommenden Jahre sind auf den ersten Blick überraschend. Nach einer De-facto-Nullrunde im laufenden Jahr folgt nach aktuellen Prognosen in den alten Ländern eine Rentenerhöhung von 4,8 % im Jahr 2022 und 3,2 % im darauffolgenden Jahr. 2024 folgt dann wieder eine Nullrunde. Die Abfolge von prognostizierten Nullrunden und Rentenanstiegen basiert dabei nicht auf Schwankungen der makroökonomischen Rahmendaten, die für die Berechnungen im Rentenversicherungsbericht angenommen werden. Sie entstehen vielmehr im Zusammenspiel mit den gesetzlichen Regelungen zur Rentenanpassung. Für das laufende und kommende Jahr gehen sie vor allen Dingen auf die Lohnkomponente der Rentenanpassungsformel zurück. Dieser Beitrag präsentiert einen Vorschlag zur Anpassung der Lohnkomponente, der das Auf und Ab der Rentenanpassungen abschwächen würde.

Optimizing Policymakers' Loss Functions in Crisis Prediction: Before, Within or After?
Peter Sarlin, Gregor von Schweinitz
Abstract
Early-warning models most commonly optimize signaling thresholds on crisis probabilities. The ex-post threshold optimization is based upon a loss function accounting for preferences between forecast errors, but comes with two crucial drawbacks: unstable thresholds in recursive estimations and an in-sample overfit at the expense of out-of-sample performance. We propose two alternatives for threshold setting: (i) including preferences in the estimation itself and (ii) setting thresholds ex-ante according to preferences only. We provide simulated and real-world evidence that this simplification results in stable thresholds and improves out-of-sample performance. Our solution is not restricted to binary-choice models, but directly transferable to the signaling approach and all probabilistic early-warning models.

Optimizing Policymakers' Loss Functions in Crisis Prediction: Before, Within or After?

Abstract
Early-warning models most commonly optimize signaling thresholds on crisis probabilities. The expost threshold optimization is based upon a loss function accounting for preferences between forecast errors, but comes with two crucial drawbacks: unstable thresholds in recursive estimations and an in-sample overfit at the expense of out-of-sample performance. We propose two alternatives for threshold setting: (i) including preferences in the estimation itself and (ii) setting thresholds ex-ante according to preferences only. Given probabilistic model output, it is intuitive that a decision rule is independent of the data or model specification, as thresholds on probabilities represent a willingness to issue a false alarm vis-à-vis missing a crisis. We provide simulated and real-world evidence that this simplification results in stable thresholds and improves out-of-sample performance. Our solution is not restricted to binary-choice models, but directly transferable to the signaling approach and all probabilistic early-warning models.

Consumer Bankruptcy, Bank Mergers and Information
Jason Allen, H. Evren Damar, David Martinez-Miera
Review of Finance,
Nr. 4,
2016
Abstract
This article analyzes the relationship between consumer bankruptcy patterns and the destruction of soft information caused by mergers. Using a major Canadian bank merger as a source of exogenous variation in local banking conditions, we show that local markets affected by the merger exhibit an increase in consumer bankruptcy rates post-merger. The evidence is consistent with the most plausible mechanism being the disruption of consumer–bank relationships. Markets affected by the merger show a decrease in the merging institutions’ branch presence and market share, including those stemming from higher switching rates. We rule out alternative mechanisms such as changes in quantity of credit, loan rates, or observable borrower characteristics.

International Banking and Liquidity Risk Transmission: Evidence from Canada
James Chapman, H. Evren Damar
IMF Economic Review,
Nr. 3,
2015
Abstract
This paper investigates how liquidity conditions in Canada may affect domestic and/or foreign lending of globally active Canadian banks, and whether this transmission is influenced by individual bank characteristics. It finds that Canadian banks expanded their foreign lending during the recent financial crisis, often through acquisitions of foreign banks. It also finds evidence that internal capital markets play a role in the lending activities of globally active Canadian banks during times of heightened liquidity risk.

Leverage, Balance-Sheet Size and Wholesale Funding
H. Evren Damar, Césaire Meh, Yaz Terajima
Journal of Financial Intermediation,
Nr. 4,
2013
Abstract
Positive co-movements in bank leverage and assets are associated with leverage procyclicality. As wholesale funding allows banks to quickly adjust leverage, banks with wholesale funding are expected to exhibit higher leverage procyclicality. Using Canadian data, we analyze (i) if leverage procyclicality exists and its dependence on wholesale funding, (ii) market factors associated with this procyclicality, and (iii) if banking-sector leverage procyclicality forecasts market volatility. The findings suggest that procyclicality exists and that its degree positively depends on use of wholesale funding. Furthermore, funding-market liquidity matters for this procyclicality. Finally, banking-sector leverage procyclicality can forecast volatility in the equity market.

Credit Union Membership and Use of Internet Banking Technology
H. Evren Damar, Lynn Hunnicutt
B.E. Journal of Economic Analysis and Policy,
Nr. 1,
2010
Abstract
What makes households use internet banking? Bank adoption of internet banking technology has been widely considered, but relatively few papers address consumer usage of internet banking. This study looks at the determinants of internet banking usage among credit union members in the Western United States. We use call report data from the National Credit Union Administration to calculate the rate of internet banking usage among a credit union's members, which allows us to examine whether variations in institutional characteristics, local economic conditions and membership criteria have an impact on the internet usage rates among members of different credit unions. We find that members in credit unions that were early internet technology adopters have higher usage rates, and that the contribution to usage rates varies among types of online services offered.

Why Do Payday Lenders Enter Local Markets? Evidence from Oregon
H. Evren Damar
Review of Industrial Organization,
Nr. 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.

A Lesson Learned? Pre- and Post-Crisis Entry Decisions in Turkish Banking
H. Evren Damar
Contemporary Economic Policy,
Nr. 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.
