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.

Total Factor Productivity Growth at the Firm-level: The Effects of Capital Account Liberalization
in: Journal of International Economics, Vol. 139 (November), 2022
Abstract
This study provides firm-level evidence on the effect of capital account liberalization on total factor productivity (TFP) growth. We find that a one standard deviation increase in the capital account openness indicator constructed by Fernández et al. (2016) is significantly associated with a 0.18 standard deviation increase in firms’ TFP growth rates. The productivity-enhancing effects are stronger for sectors with higher external finance dependence and capital-skill complementarity, and are persistent five years after liberalization. Moreover, we show that potential transmission mechanisms include improved financing conditions, greater skilled labor utilization, and technology upgrades. Finally, we document heterogeneous effects across firm size and tradability, and threshold effects with respect to the country's institutional quality.
Does Capital Account Liberalization Affect Income Inequality?
in: Oxford Bulletin of Economics and Statistics, Vol. 83 (2), 2021
Abstract
By adopting an identification strategy of difference‐in‐difference estimation combined with propensity score matching between liberalized and closed countries, this paper provides robust evidence that opening the capital account is associated with an increase in income inequality in developing countries. Specifically, capital account liberalization, in the long run, is associated with a reduction in the income share of the poorest half by 2.66–3.79% points and an increase in that of the richest 10% by 5.19–8.76% points. Moreover, directions and categories of capital account liberalization matter. The relationship is more pronounced when liberalizing inward and equity capital flows.
What Does Peer-to-Peer Lending Evidence Say About the Risk-taking Channel of Monetary Policy?
in: Journal of Corporate Finance, Vol. 66, 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, Vol. 10 (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.

Cross-border Transmission of Climate Policies Through Global Production Networks
in: IWH Discussion Papers, Nr. 19, 2025
Abstract
Climate policies do not operate in isolation but propagate through global production networks, affecting industries beyond national borders. This paper combines international input-output data with a granular instrumental variable approach to capture how foreign regulations transmit through upstream and downstream linkages. Distinguishing between market-based policies, non-market regulations, and technology support, the analysis shows that foreign climate policies can enhance domestic productivity, with effects shaped by industry characteristics and operating through technological adjustment along supply chains. The results underscore the importance of accounting for international spillovers when evaluating the economic impact of environmental regulation.
Global Banks’ Macroeconomic Expectations and Credit Supply
in: IWH Discussion Papers, Nr. 8, 2025
Abstract
We investigate how global banks’ macroeconomic expectations for borrower countries influence their credit supply. Utilizing granular data on varying expectations among banks lending to the same firm at the same time, combined with an instrumental variable approach, we find that more optimistic GDP growth expectations for a borrower country are strongly linked to increased credit supply. Specifically, a one standard deviation increase in a lender’s GDP growth expectation for the borrower’s country corresponds to an increase of 8.46 percentage points in the loan share, equivalent to approximately 0.75 standard deviations of the loan share and $75.35 million in loan amount. In contrast, global banks’ short-term inflation expectations do not show a significant impact on their credit supply.
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
Since the onset of globalization, production activities have become increasingly fragmented and organized in global value chains, facilitating the trade of intermediaries across industries and countries. In this paper, we analyze the dynamic effect of increasing participation in global value chains on both productivity growth and the functional income distribution. To account for potential endogeneity, we construct a granular instrumental variable for international trade integration using detailed international input-output tables. Our findings show on the country-industry level, that both trade in intermediate inputs and trade in value-added significantly raise productivity in advanced countries, at the expense of the labor share of income. Moreover, labor shares decline more sharply in both manufacturing and services sectors, as well as in industries positioned closer to the final stages of the global value chain. Finally, our results show that a decline in international trade integration would have substantial negative effects on long-term productivity growth.
