Abstract
In dieser Studie wird geprüft, ob die Genauigkeit der ersten Schätzung der Bruttowertschöpfung und des Bruttoinlandsprodukts für die Bundesländer erhöht und damit das Ausmaß der nachfolgenden Revisionen reduziert werden kann. Dazu werden alternative ökonometrische Methoden und zusätzliche Daten herangezogen. Zunächst wird untersucht, in welchen Bereichen die Revisionen stärker ausfallen als in anderen. Dabei werden das BIP und die Bruttowertschöpfung (BWS) auf der Wirtschaftszweig-Gliederungsebene A*10 mit Zusammenfassungen in die Untersuchung einbezogen. Anschließend werden die amtlichen Ergebnisse mit denen der alternativen Ansätze verglichen. Insgesamt ist das Ausmaß, in dem der Revisionsbedarf mit alternativen Methoden verringert werden konnte, relativ gering.

Common Venture Capital Investors and Startup Growth
Ofer Eldar, Jillian Grennan
Review of Financial Studies,
Vol. 37 (2),
2024
Abstract
We exploit the staggered introduction of liability waivers when investors hold stakes in conflicting business opportunities as a shock to venture capital (VC) investment and director networks. After the law changes, we find increases in within-industry VC investment and common directors serving on startup boards. Despite the potential for rent extraction, same-industry startups inside VC portfolios benefit by raising more capital, failing less, and exiting more successfully. VC directors serving on other startup boards are the primary mechanism associated with positive outcomes, consistent with common VC investment facilitating informational exchanges in VC portfolios.

IWH-Flash-Indikator I. und II. Quartal 2024

IWH-Flash-Indikator,
No. 1,
2024
Abstract
Im Jahr 2023 ging das deutsche Bruttoinlandsprodukt um 0,3% gegenüber dem Vorjahr zurück. Während im zweiten und dritten Quartal eine Stagnation der gesamtwirtschaftlichen Produktion zu beobachten war, sank die Wirtschaftsleistung in Deutschland im vierten Quartal 2023 um 0,3%. Insbesondere dürften die gestiegenen Verbraucherpreise dazu beigetragen haben, dass die preisbereinigten Konsumausgaben der privaten Haushalte deutlich zurückgingen. Zusätzlich belastete politische und wirtschaftliche Unsicherheit den Konsum. Der Anstieg der Zinsen wirkte im vergangenen Jahr ebenfalls dämpfend auf die Konjunktur. Die Verunsicherung wird auch in der ersten Jahreshälfte andauern, so dass das Bruttoinlandsprodukt (BIP) laut IWH-Flash-Indikator im ersten Quartal 2024 stagnieren und im zweiten Quartal 2024 lediglich um knapp 0,2% steigen dürfte (vgl. Abbildung 1).

Financial Technologies and the Effectiveness of Monetary Policy Transmission
Iftekhar Hasan, Boreum Kwak, Xiang Li
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.

Macroeconomic Effects from Sovereign Risk vs. Knightian Uncertainty

IWH Discussion Papers,
No. 27,
2023
Abstract
This paper compares macroeconomic effects of Knightian uncertainty and risk using policy shocks for the case of Italy. Drawing on the ambiguity literature, I use changes in the bid-ask spread and mid-price of government bonds as distinct measures for uncertainty and risk. The identification exploits the quasi-pessimistic behavior under ambiguity-aversion and the dealer market structure of government bond markets, where dealers must quote both sides of the market. If uncertainty increases, ambiguity-averse dealers will quasi-pessimistically quote higher ask and lower bid prices – increasing the bid-ask spread. In contrast, a pure change in risk shifts the risk-compensating discount factor which is well approximated by the change in bond mid-prices. I evaluate economic effects of the two measures within an instrumental variable local projection framework. The main findings are threefold. First, the resulting shock time series for uncertainty and risk are uncorrelated with each other at the intraday level, however, upon aggregation to monthly level the measures become correlated. Second, uncertainty is an important driver of economic aggregates. Third, macroeconomic effects of risk and uncertainty are similar, except for the response of prices. While sovereign risk raises inflation, uncertainty suppresses price growth – a result which is in line with increased price rigidity under ambiguity.
