Abstract
We build a model of firm-level innovation, productivity growth, and reallocation featuring endogenous entry and exit. A new and central economic force is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model using US Census microdata on firm-level output, R&D, and patenting. The model provides a good fit to the dynamics of firm entry and exit, output, and R&D. Taxing the continued operation of incumbents can lead to sizable gains (of the order of 1.4 percent improvement in welfare) by encouraging exit of less productive firms and freeing up skilled labor to be used for R&D by high-type incumbents. Subsidies to the R&D of incumbents do not achieve this objective because they encourage the survival and expansion of low-type firms.

Ostdeutsche Flächenländer können mit westdeutschem Wirtschaftswachstum nicht mithalten
Deutschlands Wirtschaft ist im Jahr 2017 um stolze 2,2% gewachsen. Bei näherem Hinsehen offenbart sich aber schnell: Die Wachstumszahlen von Bundesländern wie Bayern (+2,8%), Bremen (+3,3%) und Niedersachsen (+2,5%) verheißen deutlich mehr als die der ostdeutschen Flächenländer, beispielsweise die Sachsens (+1,4%) und vor allem Sachsen-Anhalts (0,8%), wie die heute vorgelegten BIP-Wachstumszahlen des Arbeitskreises Volkswirtschaftliche Gesamtrechnungen der Länder (VGRdL) für 2017 zeigen. Damit geht die Schere zwischen Ost- und Westdeutschland nicht weiter zu. „Der Aufholprozess stagniert; die ostdeutschen Länder sollten ihre Wirtschaftspolitik mehr auf die bessere Qualifizierung der Erwerbstätigen und Innovationen ausrichten“, so Oliver Holtemöller, Vizepräsident des Leibniz-Instituts für Wirtschaftsforschung Halle (IWH) und Leiter der Abteilung Makroökonomik.

Inside Asset Purchase Programs: The Effects of Unconventional Policy on Banking Competition
Michael Koetter, Natalia Podlich, Michael Wedow
ECB Working Paper Series,
No. 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.

IT Use, Productivity, and Market Power in Banking
Michael Koetter, Felix Noth
Journal of Financial Stability,
No. 4,
2013
Abstract
Information management is a core process in banking that can resolve information asymmetries and thereby help to mitigate competitive pressure. We test if the use of information technology (IT) contributes to bank output, and how IT-augmented bank productivity relates to differences in market power. Detailed bank-level information on the use of IT reveals a substantial upward bias in bank productivity estimates when ignoring banks’ IT expenditures. IT-augmented bank productivity correlates positively with Lerner markups. A mere increase in IT expenditures, however, reduces markups. Results hold across a range of bank output definitions and productivity estimation methods.

Preventing Innovative Cooperations: The Legal Exemptions Unintended Side Effect
Christian Growitsch, Nicole Nulsch, Margarethe Rammerstorfer
European Journal of Law and Economics,
No. 1,
2012
Abstract
In 2004, European competition law had been considerable changed by the introduction of the new Council Regulation No. 1/2003. One of the major renewals was the replacement of the centralized notification system for inter-company cooperations in favor of a so-called legal exemption system. We analyze the implications of this reform and its arising uncertainty on the agreements firms implement, especially on innovative agreements like vertical R&D agreements. By means of a decision theoretic approach, we show that the law’s intention to reduce the incentive to establish illegal cartels will be reached but innovating cooperations might be prevented. To avoid this unintended side effect, fines but not the monitoring activities should be increased.

Preventing Innovative Cooperations: The Legal Exemptions Unintended Side Effect

Abstract
In 2004, European competition law had been faced with considerable changes due to the introduction of the new Council Regulation No. 1/2003. One of the major renewals was the replacement of the centralized notification system for inter-company cooperations in favor of a so-called legal exemption system. We analyze the implications of this reform on the agreements firms implement. In contrast to previous research we focus on the reform’s impact on especially welfare enhancing, namely innovative agreements. We show that the law’s intention to reduce the incentive to establish illegal cartels will be reached. However, by the same mechanism, also highly innovative cooperations might be prevented. To avoid this unintended effect, we conclude that only fines but not the monitoring activities should be increased in order to deter illegal but not innovative agreements.

An Assessment of Bank Merger Success in Germany
Michael Koetter
German Economic Review,
No. 2,
2008
Abstract
German banks have experienced a merger wave since the early 1990s. However, the success of bank mergers remains a continuous matter of debate.This paper suggests a taxonomy to evaluate post-merger performance on the basis of cost and profit efficiency (CE and PE). I identify successful mergers as those that fulfill simultaneously two criteria. First, merged institutes must exhibit efficiency levels above the average of non-merging banks. Second, banks must exhibit efficiency changes between merger and evaluation year above efficiency changes of non-merging banks. I assess the post-merger performance up to 11 years after the mergers and relate it to the transfer of skills, the adequacy to merge distressed banks and the role of geographical distance. Roughly every second merger is a success in terms of either CE or PE. The margin of success in terms of CE is narrow, as efficiency differentials between merging and non-merging banks are around 1 and 2 percentage points. PE performance is slightly larger. More importantly, mergers boost in particular the change in PE, thus indicating persistent improvements of merging banks to improve the ability to generate profits.

Environmental policy under product differentiation and asymmetric costs - Does leapfrogging occur and is it worth it?
Jacqueline Rothfels
IWH Discussion Papers,
No. 124,
2000
Abstract
This paper studies the influence of environmental policies on environmental quality, domestic firms, and welfare. Point of departure is Porter’s hypothesis that unilateral environmental regulation may enhance the competitiveness of domestic firms. This hypothesis has recently received considerable support in theoretical analyses, especially if imperfectly competitive markets with strategic behavior on behalf of the agents are taken into account. Our work contributes to this literature by explicitely investigating the implications of asymmetric cost structures between a domestic and a foreign firm sector. We use a partial-equilibrium model of vertical product differentiation, where the consumption of a product causes environmental harm. Allowing for differentiated products, the domestic industry can either assume the market leader position or lag behind in terms of the environmental quality of the produced product. Assuming as a benchmark case that the domestic industry lags behind, we investigate the possibility of the government to induce leapfrogging of the domestic firm, i.e. a higher quality produced by the domestic firm after regulation than that of the competitor prior to regulation. It is shown that in the case of a cost advantage for the domestic firm in the production process the imposition of a binding minimum quality standard can serve as a tool to induce leapfrogging. In case of a cost disadvantage the same result can be achieved through an adequate subsidization of quality dependend production costs. Thus, careful regulation enables the domestic firm in both scenarios to better its competitive position against foreign competitors and to earn larger profits. Additionally, environmental quality and welfare can be enhanced.

Explaining Regional Disparities in Housing Prices across German Districts

Abstract
Over the last decade, German housing prices have increased unprecedentedly. Drawing on quality-adjusted housing price data at the district level, we document large and increasing regional disparities: growth rates were higher in 1) the largest seven cities, 2) districts located in the south, and 3) districts with higher initial price levels. Indications of price bubbles are concentrated in the largest cities and in the purchasing market. Prices seem to be driven by the demand side: increasing population density, higher shares of academically educated employees and increasing purchasing power explain our findings, while supply remained relatively constrained in the short term.
