Eine Hochfrequenzanalyse zur Abgrenzung von überlagernden Effekten am Beispiel des Ausfallrisikos italienischer Staatsanleihen

Abstract
Die wirtschaftliche Aktivität und das Ausfallrisiko staatlicher Schulden beeinflussen sich gegenseitig. Sinkt die wirtschaftliche Aktivität einer Volkswirtschaft, steigt wegen fallender Steuereinnahmen das Risiko, dass der Staat Zinszahlungen und Tilgungen auf Staatsanleihen nicht zurückzahlen kann. Umgekehrt kann das staatliche Ausfallrisiko seinerseits die wirtschaftliche Aktivität beeinflussen. Steigt das Ausfallrisiko, geraten Banken unter Druck, die Staatsanleihen in ihren Bilanzen führen, und reduzieren die Kreditvergabe an Unternehmen. In der Konsequenz sinkt die wirtschaftliche Aktivität. Dieser Beitrag nutzt hochfrequente News-Ticker-Daten zur Ableitung politischer Ereignisse und davon ausgelöster Fluktuationen im Staatsschuldenrisiko. Diese allein politisch bedingten Fluktuationen ermöglichen es, den Effekt des Staatsschuldenrisikos auf die wirtschaftliche Aktivität zu messen, ohne dass die Schätzung von der gegenläufigen Beziehung der Variablen beeinträchtigt wird. Das Vorgehen wird am Beispiel Italiens erläutert.

Aktuelle Trends: Staatsverbrauch wieder zurück auf Vor-Covid-Trend

Abstract
Der vierteljährliche Staatsverbrauch in Abgrenzung der Volkswirtschaftlichen Gesamtrechnungen ist im ersten Quartal 2023 wieder annähernd zurück auf den Vor-Covid-Trend gefallen. Mit dem Ausbruch der Corona-Pandemie im Frühjahr 2020 hatte der Staatsverbrauch deutlich zugenommen, weil dort zahlreiche Maßnahmen verbucht wurden, die der Staat zur Bewältigung der Pandemie ergriffen hat, etwa der Kauf von Schutzausrüstung, Corona-Tests, medizinische Behandlungen oder finanzielle Zuwendungen an Krankenhäuser.

The East-West German Gap in Revenue Productivity: Just a Tale of Output Prices?
Matthias Mertens, Steffen Müller
Journal of Comparative Economics,
Nr. 3,
2022
Abstract
East German manufacturers’ revenue productivity is substantially below West German levels, even three decades after German unification. Using firm-product-level data with product quantities and prices, we analyze the role of product specialization and show that the prominent “extended work bench hypothesis” cannot explain these sustained productivity differences. Eastern firms specialize in simpler product varieties generating less consumer value and being manufactured with less or cheaper inputs. Yet, such specialization cannot explain the productivity gap because Eastern firms are physically less productive for given product prices. Hence, there is a genuine price-adjusted physical productivity disadvantage of Eastern compared to Western firms.

Trust and Contracting with Foreign Banks: Evidence from China

Abstract
We empirically investigate whether firms doing business in regions characterized as having high social trust receive preferential treatment on loan contractual terms by foreign banks. Tracing cross-border syndicated lending activities in China, we document that firms located in provinces with higher social trust scores obtain significantly low costs of bank loans and experience less stringent collateral requirement. To address the potential endogeneity issues, we adopt an instrumental variable approach and a two-sided matching model, and report consistent results. We also estimate a system of three equations through three-stage-least square estimator to accommodate the joint determination of price and non-price terms in loan contracts. In addition, we find that the effect of social trust on cost of bank loans is more prominent for firms located in provinces with relatively less developed formal institutions.

Corporate Culture and Firm Value: Evidence from Crisis

Abstract
Based on the Competing Values Framework (CVF), we score 10-K text to measure company culture in four types (collaborative, controlling, competitive, and creative) and examine its role in firm stability. We find that firms with higher controlling culture fared significantly better during the 2008–09 crisis. Firms with stronger controlling culture experienced fewer layoffs, less negative asset growth, greater debt issuance, and increased access to credit-line facilities during the crisis. The positive effect of the controlling culture is stronger among the financially-constrained firms. Overall, the controlling culture improves firm stability through greater support from capital providers.

Cultural Values of Parent Bank Board Members and Lending by Foreign Subsidiaries: The Moderating Role of Personal Traits
Iftekhar Hasan, Krzysztof Jackowicz, Oskar Kowalewski, Łukasz Kozłowski
Journal of International Financial Markets, Institutions and Money,
March
2023
Abstract
In this study, we investigate whether the cultural values of a parent bank’s board members affect lending by the bank’s foreign subsidiaries and how this influence is moderated by the board members’ personal traits. Using a new dataset on foreign-owned banks and their parent companies, we find that average individualism, uncertainty avoidance, and indulgence within parent bank boards significantly impact lending by foreign subsidiaries. We establish that different sensitivities of female and male directors modify the relevance of individual cultural dimensions in lending by foreign bank subsidiaries. Moreover, we show that parent bank directors’ cultural values have a stronger impact on lending by the bank’s foreign subsidiaries when those directors have enough time to fulfill their duties and possess higher ownership stakes in the parent companies.

The Effects of Antitrust Laws on Horizontal Mergers: International Evidence

im Erscheinen
Abstract
This study examines how antitrust law adoptions affect horizontal merger and acquisition (M&A) outcomes. Using the staggered introduction of competition laws in 20 countries, we find antitrust regulation decreases acquirers’ five-day cumulative abnormal returns surrounding horizontal merger announcements. A decrease in deal value, target book assets, and industry peers' announcement returns are consistent with the market power hypothesis. Exploiting antitrust law adoptions addresses a downward bias to an estimated effect of antitrust enforcement (Baker (2003)). The potential bias from heterogeneous treatment effects does not nullify our results. Overall, antitrust policies seem to deter post-merger monopolistic gains, potentially improving customer welfare.

The Investment Strategies of Sovereign Wealth Funds
Shai B. Bernstein, Josh Lerner, Antoinette Schoar
Journal of Economic Perspectives,
Nr. 2,
2013
Abstract
Sovereign wealth funds have emerged as major investors in corporate and real resources worldwide. After an overview of their magnitude, we consider the institutional arrangements under which many of the sovereign wealth funds operate. We focus on a specific set of agency problems that is of first-order importance for these funds: that is, the direct involvement of political leaders in the management process. We show that sovereign wealth funds with greater involvement of political leaders in fund management are associated with investment strategies that seem to favor short-term economic policy goals in their respective countries at the expense of longer-term maximization of returns. Sovereign wealth funds face several other issues, like how best to cope with demands for transparency, which can allow others to copy their investment strategies, and how to address the problems that arise with sheer size, like the difficulties of scaling up investment strategies that only work with a smaller value of assets under investment. In the conclusion, we discuss how various approaches cultivated by effective institutional investors worldwide -- from investing in the best people to pioneering new asset classes to compartmentalizing investment activities -- may provide clues as to how sovereign wealth funds might address these issues.
