Internationale Integration der Finanzmärkte, Wirtschaftswachstum und Finanzstabilität
Die internationale Integration der Finanzmärkte ist einer der wichtigsten weltwirtschaftlichen Trends der Gegenwart. Diese Forschungsgruppe analysiert die Rolle der internationalen Finanzintegration für Wirtschaftswachstum und Finanzstabilität.
Aus neoklassischer Sicht erhöht ein integrierter globaler Finanzmarkt das Wirtschaftswachstum, denn er senkt die Kapitalkosten und ermöglicht die Diversifikation von Risiken. Länder mit liberalisiertem internationalen Kapitalverkehr schneiden jedoch nicht unbedingt besser ab als Volkswirtschaften mit Kapitalverkehrskontrollen; und die jüngste Weltfinanzkrise hat sogar dazu geführt, dass sich Finanzmärkte teilweise wieder disintegrieren. Die Neubewertung der Rolle der Finanzintegration für Wirtschaftswachstum und Finanzstabilität scheint also von erheblicher Bedeutung, aus wirtschaftspolitischer Sicht ebenso wie für die akademische Forschung.
Diese Forschungsgruppe soll Antworten auf folgende Fragen suchen: Erstens untersucht die Gruppe, wie die Produktivität von Unternehmen vom Zugang zu internationalem Kapital beeinflusst wird und ob kapitalintensive Sektoren in besonderem Maße von der Liberalisierung des Kapitalverkehrs profitieren. Darüber hinaus untersucht diese Gruppe die strukturellen Transformationsfolgen der finanziellen Integration. Zweitens erreicht internationales Kapital die Realwirtschaft über die Vermittlung durch Finanzinstitute. Die Gruppe analysiert, ob der grenzüberschreitende Kapitalfluss das Verhalten der Banken ändert und insbesondere, wie die Finanzierungslaufzeit, die Struktur und das systemische Risiko beeinflusst werden. Drittens haben internationale Organisationen wie der IWF eine schrittweise Liberalisierung des Kapitalverkehrs vorgeschlagen. So soll die Liberalisierung der Kapitalimporte zeitlichen Vorrang haben vor derjenigen für Kapitalexporte, und die Liberalisierung von Direktinvestitionen soll vor derjenigen von Investitionen in Krediten und Wertpapieren kommen. Es gibt allerdings derzeit noch wenige empirische Arbeiten, die diese Empfehlungen stützen. Die Forschungsgruppe untersucht, ob und wie die Sequenzierung der Kapitalverkehrsliberalisierung für die finanzielle Stabilität von Bedeutung ist.

What Does Peer-to-Peer Lending Evidence Say About the Risk-taking Channel of Monetary Policy?
in: Journal of Corporate Finance, 2021
Abstract
This paper uses loan application-level data from a peer-to-peer lending platform to study the risk-taking channel of monetary policy. By employing a direct ex-ante measure of risk-taking and estimating the simultaneous equations of loan approval and loan amount, we provide evidence of monetary policy's impact on a nonbank financial institution's risk-taking. We find that the search-for-yield is the main driving force of the risk-taking effect, while we do not observe consistent findings of risk-shifting from the liquidity change. Monetary policy easing is associated with a higher probability of granting loans to risky borrowers and greater riskiness of credit allocation. However, these changes do not necessarily relate to a larger loan amount on average.
From World Factory to World Investor: The New Way of China Integrating into the World
in: China Economic Journal, Nr. 2, 2017
Abstract
This paper argues that outward direct investment (ODI) is replacing international trade as the new way China integrates into the world. Based on two complementary datasets, we document the pattern of Chinese ODI. We argue that the rapid growth of China’s ODI is the result of strong economic development, increasing domestic constraints, and supportive government policies. Compared with trade integration, investment integration involves China more deeply in global business. As a new global investor, China’s ODI in the future is full of opportunities, risks, and challenges. The Chinese government should improve bureaucracy coordination and participate more in designing and maintaining international rules to protect ODI interests.

Climate Policy and International Capital Reallocation
in: IWH Discussion Papers, Nr. 20, 2024
Abstract
<p>This study employs bilateral data on external assets to examine the impact of climate policies on the reallocation of international capital. We find that the stringency of climate policy in the destination country is significantly and positively associated with an increase in the allocation of portfolio equity and banking investment to that country. However, it does not show significant effects on the allocation of foreign direct investment and portfolio debt. Our findings are not driven by valuation effects, and we present evidence that suggests diversification, suasion, and uncertainty mitigation as possible underlying mechanisms.</p>
Global Political Ties and the Global Financial Cycle
in: IWH Discussion Papers, Nr. 23, 2023
Abstract
We study the implications of forging stronger political ties with the US on the sensitivities of stock returns around the world to a global common factor – the global financial cycle. Using voting patterns at the United Nations as a measure of political ties with the US along with various measures of the global financial cycle, we document evidence indicating that stronger political ties with the US amplify the sensitivities of stock returns in developing countries to the global financial cycle. We explore several channels and find that a deepening of financial linkages along with a reduction in information asymmetries and an amplification of sentiment are potentially important factors behind this result.
BigTech Credit, Small Business, and Monetary Policy Transmission: Theory and Evidence
in: IWH Discussion Papers, Nr. 18, 2022
Abstract
This paper provides both theoretical and empirical analyses of the differences between BigTech lenders and traditional banks in response to monetary policy changes. Our model integrates Knightian uncertainty into portfolio selection and posits that BigTech lenders possess a diminishing informational advantage with increasing firm size, resulting in reduced ambiguity when lending to smaller firms. The model suggests that the key distinction between BigTech lenders and traditional banks in response to shifts in funding costs, triggered by monetary policy changes, is more evident at the extensive margin rather than the intensive margin, particularly during periods of easing monetary policy. Using a micro-level dataset of small business loans from both types of lenders, we provide empirical support for our theoretical propositions. Our results show that BigTech lenders are more responsive in establishing new lending relationships in an easing monetary policy environment, while the differences in loan amounts are not statistically significant. We also discuss other loan terms and the implications of regulatory policies.
Globalization, Productivity Growth, and Labor Compensation
in: IWH Discussion Papers, Nr. 7, 2022
Abstract
We analyze how changes in international trade integration affect productivity and the functional income distribution. To account for endogeneity, we construct a leaveout measure for international trade integration for country-industry pairs using international input-output tables. Our findings corroborate on the country-industry level that international trade integration increases productivity. Moreover, we show that both trade in intermediate inputs and trade in value added is associated with lower labor shares in emerging markets. For advanced countries, we document a positive effect of trade in value added on the labor share of income. Further, we show that the effects on productivity and labor share are heterogeneous across different sectors. Finally, we discuss the implications of our results for a possible throwback in international trade integration due to experiences from recent crises.
The Role of State-owned Banks in Crises: Evidence from German Banks During COVID-19
in: IWH Discussion Papers, Nr. 6, 2022
Abstract
By adopting a difference-in-differences specification combined with propensity score matching, I provide evidence using the microdata of German banks that stateowned savings banks have lent less than credit cooperatives during the COVID-19 crisis. In particular, the weaker lending effects of state-owned banks are pronounced for long-term and nonrevolving loans but insignificant for short-term and revolving loans. Moreover, the negative impact of government ownership is larger for borrowers who are more exposed to the COVID-19 shock and in regions where the ruling parties are longer in office and more positioned on the right side of the political spectrum.
