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.

Climate Policy and International Capital Reallocation
in: Journal of Financial Stability, Vol. 82 (February), 2026
Abstract
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.
Geopolitical Tensions And Multinational Brands: Evidence From China
in: Finance Research Letters, Vol. 85 (November), 2025
Abstract
Using brand-level sales data from Chinese e-commerce platforms, this study examines how geopolitical tensions affect multinational brands operating in China. Merging these sales data with a U.S.–China tension index, we use panel regressions and local projections to show that rising tensions significantly reduce the market share of U.S. brands in China relative to brands from other countries, with the effects persisting for up to 12 months. An event study employing a difference-in-differences framework, centered on brand-specific incidents of political tension with China, reveals similar market share declines among affected brands, highlighting consumer sentiment as a key transmission channel.
Financial Technologies and the Effectiveness of Monetary Policy Transmission
in: European Economic Review, Vol. 161 (January), 2024
Abstract
This study investigates whether and how financial technologies (FinTech) influence the effectiveness of monetary policy transmission. We use an interacted panel vector autoregression model to explore how the effects of monetary policy shocks change with regional-level FinTech adoption. Results indicate that FinTech adoption generally mitigates the transmission of monetary policy to real GDP, consumer prices, bank loans, and housing prices, with the most significant impact observed in the weakened transmission to bank loan growth. The relaxed financial constraints, regulatory arbitrage, and intensified competition are the possible mechanisms underlying the mitigated transmission.
Household Indebtedness, Financial Frictions and the Transmission of Monetary Policy to Consumption: Evidence from China
in: Emerging Markets Review, Vol. 55 (June), 2023
Abstract
This paper studies the impact of household indebtedness on the transmission of monetary policy to consumption using the Chinese household-level survey data. We employ a panel smooth transition regression model to investigate the non-linear role of indebtedness. We find that housing-related indebtedness weakens the monetary policy transmission, and this effect is non-linear as there is a much larger counteraction of consumption in response to monetary policy shocks when household indebtedness increases from a low level rather than from a high level. Moreover, the weakened monetary policy transmission from indebtedness is stronger in urban households than in rural households. This can be explained by the investment good characteristic of real estate in China.
Surges and Instability: The Maturity Shortening Channel
in: Journal of International Economics, Vol. 139 (November), 2022
Abstract
Capital inflow surges destabilize the economy through a maturity shortening mechanism. The underlying reason is that firms have incentives to redeem their debt on demand to accommodate the potential liquidity needs of global investors, which makes international borrowing endogenously fragile. Based on a theoretical model and empirical evidence at both the firm and macro levels, our main findings are twofold. First, a significant association exists between surges and shortened corporate debt maturity, especially for firms with foreign bank relationships and higher redeployability. Second, the probability of a crisis following surges with a flattened yield curve is significantly higher than that following surges without one. Our study suggests that debt maturity is the key to understand the financial instability consequences of capital inflow bonanzas.

Within Gain, Structural Pain: Capital Account Liberalization and Economic Growth
in: New Structural Economics Working Paper No. E2018010, 2018
Abstract
This paper is the first to study the effects of capital account liberalization on structural transformation and compare the contribution of within term and structural term to economic growth. We use a 10-sector-level productivity dataset to decomposes the effects of opening capital account on within-sector productivity growth and cross-sector structural transformation. We find that opening capital account is associated with labor productivity and employment share increment in sectors with higher human capital intensity and external financial dependence, as well as non-tradable sectors. But it results in a growth-reducing structural transformation by directing labor into sectors with lower productivity. Moreover, in the ten years after capital account liberalization, the contribution share of structural transformation decreases while that of within productivity growth increases. We conclude that the relationship between capital account liberalization and economic growth is within gain and structural pain.
