Dekarbonisierung in Europa: Regionalwirtschaftliche Effekte in ausgewählten Kohleregionen und kohlenstoffintensiven Regionen Europa
Katja Heinisch, Oliver Holtemöller, Christoph Schult
Wirtschaft im Wandel,
Nr. 3,
2023
Abstract
Die EU hat mit dem „Fit for 55“-Paket zwei große klimapolitische Ziele festgelegt: die Senkung der Treibhausgasemissionen um 55% bis zum Jahr 2030 und Treibhausgasneutralität ab dem Jahr 2050. Im Rahmen des EU-Horizon-2020-Projekts ENTRANCES werden die gesellschaftlichen Effekte der Dekarbonisierung und besonders des Kohleausstiegs in verschiedenen europäischen Regionen interdisziplinär analysiert und darauf basierend Handlungsempfehlungen für die Politik abgeleitet. Der vorliegende Beitrag stellt erste analytische Ergebnisse vor.

Lending Effects of the ECB’s Asset Purchases
Michael Koetter
Journal of Monetary Economics,
December
2020
Abstract
Between 2010 and 2012, the European Central Bank absorbed €218 billion worth of government securities from five EMU countries under the Securities Markets Programme (SMP). Detailed security holdings data at the bank level affirms an effective lending stimulus due to the SMP. Exposed banks contract household lending, but increase commercial lending substantially. Holding non-SMP securities from stressed EMU countries amplifies the commercial lending response. The SMP also improved liquidity buffers and profitability without compromising credit quality.

Does it Payoff to Research Economics? A Tale of Citation, Knowledge and Economic Growth in Transition Countries
Dejan Kovač, Boris Podobnik, Nikol Scrbec
Physica A: Statistical Mechanics and its Applications,

2018
Abstract
There are many economic theories that promote human capital as a key driver of a country’s economic growth, but it is challenging to test this theory empirically on a country level and causally interpret the coefficients due to several identification problems. We tried to answer this particular question by using a quasi-natural experiment that happened quarter century ago – the fall of communist block in Eastern Europe. We use a shock to a particular scientific field – economics, to test whether the future investment into that particular field resulted in increased welfare and economic growth. The economics paradigm that was governing all of the communist block ceased to exist. Human capital depreciated over night and all communist countries had to transit from planned economy to a market economy. In the following years countries had to adapt to market economy through additional investment in human capital and research. We find that countries which lack both of the two fourth mentioned components had 25 years later a relatively lower economic growth and wealth. Unlike economics, other fields such as physics and medicine did not go through the same process so we use them as a placebo effect for our study. We find that the relative ratio of citations between economics and physics in post-communist countries is increasing only 15 years after the “paradigm” shock which gives a suggestive evidence that timing of investment into particular scientific field matters the most.

Messbar, aber milde: Auswirkungen des SMP-Wertpapier-Ankaufprogramms der EZB auf den regionalen Bankenwettbewerb in Deutschland
Friederike Altgelt, Michael Koetter
Wirtschaft im Wandel,
Nr. 3,
2017
Abstract
Die Europäische Zentralbank (EZB) hat mit dem Securities Markets Programme (SMP) im Mai 2010 ein Instrument unkonventioneller Geldpolitik eingeführt. Im Rahmen des SMP erwarb sie im Wert von 218 Mrd. Euro Staatsanleihen ausgewählter Länder, welche erhöhten Risikoaufschlägen am Kapitalmarkt ausgesetzt waren. Eine mögliche Nebenwirkung solcher Ankaufprogramme ist es, auch jene Banken zu stützen, die nicht zum direkten Adressatenkreis gehören, aber Anleihen betroffener Länder in ihren Portfolios hielten. Möglicherweise resultierende Refinanzierungs-, Ertrags-, und Liquiditätsvorteile für bevorteilte Banken könnten zu Wettbewerbsverzerrungen führen. Dieser Beitrag betrachtet deshalb die Wertpapierportfolios regionaler deutscher Banken, um den kausalen Effekt des SMP auf das Wettbewerbsverhalten zu identifizieren. Die empirischen Befunde belegen in der Tat eine statistisch nachweisbare Zunahme der lokalen Marktanteile jener regionalen Banken, welche Anleihen in ihren Portfolios hielten, die Teil des SMP waren. Während dieses Ergebnis somit einen Beleg für die Existenz unbeabsichtigter Nebenwirkungen unkonventioneller Geldpolitik darstellt, so ist auch festzuhalten dass diese Wettbewerbseffekte ausgesprochen klein sind. Somit ist zumindest für den regionalen Bankenmarkt in Deutschland keine nennenswerte Verwerfung aufgrund dieses Ankaufprogramms festzustellen.

Inside Asset Purchase Programs: The Effects of Unconventional Policy on Banking Competition
Michael Koetter, Natalia Podlich, Michael Wedow
ECB Working Paper Series,
Nr. 2017,
2017
Abstract
We test if unconventional monetary policy instruments influence the competitive conduct of banks. Between q2:2010 and q1:2012, the ECB absorbed Euro 218 billion worth of government securities from five EMU countries under the Securities Markets Programme (SMP). Using detailed security holdings data at the bank level, we show that banks exposed to this unexpected (loose) policy shock mildly gained local loan and deposit market shares. Shifts in market shares are driven by banks that increased SMP security holdings during the lifetime of the program and that hold the largest relative SMP portfolio shares. Holding other securities from periphery countries that were not part of the SMP amplifies the positive market share responses. Monopolistic rents approximated by Lerner indices are lower for SMP banks, suggesting a role of the SMP to re-distribute market power differentially, but not necessarily banking profits.

Impulse Response Analysis in a Misspecified DSGE Model: A Comparison of Full and Limited Information Techniques
Sebastian Giesen, Rolf Scheufele
Applied Economics Letters,
Nr. 3,
2016
Abstract
In this article, we examine the effect of estimation biases – introduced by model misspecification – on the impulse responses analysis for dynamic stochastic general equilibrium (DSGE) models. Thereby, we use full and limited information estimators to estimate a misspecified DSGE model and calculate impulse response functions (IRFs) based on the estimated structural parameters. It turns out that IRFs based on full information techniques can be unreliable under misspecification.

Effects of Incorrect Specification on the Finite Sample Properties of Full and Limited Information Estimators in DSGE Models
Sebastian Giesen, Rolf Scheufele
Journal of Macroeconomics,
June
2016
Abstract
In this paper we analyze the small sample properties of full information and limited information estimators in a potentially misspecified DSGE model. Therefore, we conduct a simulation study based on a standard New Keynesian model including price and wage rigidities. We then study the effects of omitted variable problems on the structural parameter estimates of the model. We find that FIML performs superior when the model is correctly specified. In cases where some of the model characteristics are omitted, the performance of FIML is highly unreliable, whereas GMM estimates remain approximately unbiased and significance tests are mostly reliable.

Nested Models and Model Uncertainty
Alexander Kriwoluzky, Christian A. Stoltenberg
Scandinavian Journal of Economics,
Nr. 2,
2016
Abstract
Uncertainty about the appropriate choice among nested models is a concern for optimal policy when policy prescriptions from those models differ. The standard procedure is to specify a prior over the parameter space, ignoring the special status of submodels (e.g., those resulting from zero restrictions). Following Sims (2008, Journal of Economic Dynamics and Control 32, 2460–2475), we treat nested submodels as probability models, and we formalize a procedure that ensures that submodels are not discarded too easily and do matter for optimal policy. For the United States, we find that optimal policy based on our procedure leads to substantial welfare gains compared to the standard procedure.

Toward a Taylor Rule for Fiscal Policy
Martin Kliem, Alexander Kriwoluzky
Review of Economic Dynamics,
Nr. 2,
2014
Abstract
In DSGE models, fiscal policy is typically described by simple rules in which tax rates respond to the level of output. We show that there is only weak empirical evidence in favor of such specifications in US data. Instead, the cyclical movements of labor and capital income tax rates are better described by a contemporaneous response to hours worked and investment, respectively. We show that conditioning on these variables is also desirable from a normative perspective as it significantly improves welfare relative to output-based rules.
