Using a unique firm-level sample of approximately 700,000 firm-year observations of German small and medium-sized enterprises (SMEs), this study seeks to identify the effect of bank market power on aggregate growth components. We test for a pre-crisis sample whether bank market power spurs or hinders the reallocation of resources across informationally opaque firms. Identification relies on the dependence on external finance in each industry and the regional demarcation of regional banking markets in Germany. The results show that bank markups spur aggregate SME growth, primarily through technical change and the reallocation of resources. Banks seem to need sufficient markups to generate the necessary private information to allocate financial funds efficiently.

This study examines whether and how the stress testing of European banks in 2010, 2011, and 2014 is related to their technical, allocative, and cost efficiency. Using a sample of large commercial banks operating in 20 European countries, and Data Envelopment Analysis (DEA), the authors perform comparisons between banks that were included in one of the three European stress tests and untested banks operating in the same countries. They estimate various specifications as for the inputs and outputs, cross-section and pooled estimations, and they also examine alternative samples as for the ownership of banks. In general, the authors conclude that banks included in the stress-test exercises are more efficient that their counterparties. The differences tend to be statistically significant in the case of allocative efficiency and cost efficiency, but not in the case of technical efficiency. With regards to the latter form of efficiency, the results depend upon the specification and the stress test in question.

In the wake of the recent financial crisis, many governments extended public guarantees to banks. We take advantage of a natural experiment, in which long-standing public guarantees were removed for a set of German banks following a lawsuit, to identify the real effects of these guarantees on the allocation of credit (“allocative efficiency”). Using matched bank/firm data, we find that public guarantees reduce allocative efficiency. With guarantees in place, poorly performing firms invest more and maintain higher rates of sales growth. Moreover, firms produce less efficiently in the presence of public guarantees. Consistently, we show that guarantees reduce the likelihood that firms exit the market. These findings suggest that public guarantees hinder restructuring activities and prevent resources to flow to the most productive uses.

Angesichts der teilweise prekären Finanzlage deutscher Kommunen gelten freiwillige Kooperationen im Kommunalbereich als mögliche Alternative, z. B. zu politisch heiklen Gebietsreformen, um Kostenersparnisse zu realisieren. Die Ergebnisse einer Effizienzstudie des IWH (in Kooperation mit der Universität Kassel) zeigen am Beispiel der hessischen kommunalen Abwasserentsorgung allerdings, dass sich nicht jede Form der kommunalen Zusammenarbeit bzw. Arbeitsteilung günstig auf die Effizienz der Leistungserstellung auswirken muss. Insbesondere die verbreitete Teilzweckverbandslösung schneidet hier eher ungünstig ab. Weitere Ergebnisse zeigen neben einem erheblichen Effizienzsteigerungspotenzial auch eine weitgehende Ausschöpfung von Größenvorteilen. Daneben bestätigt sich außerdem der erhebliche Einfluss demographischer und siedlungsstruktureller Faktoren für die effiziente Abwassersammlung und -behandlung.

Drawing from confidential firm-level balance sheets in 11 European countries, the paper presents a novel sectoral database of comparable productivity indicators built by members of the Competitiveness Research Network (CompNet) using a newly developed research infrastructure. Beyond aggregate information available from industry statistics of Eurostat or EU KLEMS, the paper provides information on the distribution of firms across several dimensions related to competitiveness, e.g. productivity and size. The database comprises so far 11 countries, with information for 58 sectors over the period 1995-2011. The paper documents the development of the new research infrastructure, describes the database, and shows some preliminary results. Among them, it shows that there is large heterogeneity in terms of firm productivity or size within narrowly defined industries in all countries. Productivity, and above all, size distribution are very skewed across countries, with a thick left-tail of low productive firms. Moreover, firms at both ends of the distribution show very different dynamics in terms of productivity and unit labour costs. Within-sector heterogeneity and productivity dispersion are positively correlated to aggregate productivity given the possibility of reallocating resources from less to more productive firms. To this extent, we show how allocative efficiency varies across countries, and more interestingly, over different periods of time. Finally, we apply the new database to illustrate the importance of productivity dispersion to explain aggregate trade results. 

Informationally efficient prices are a necessary requirement for optimal resource allocation in the real estate market. Prices are informationally efficient if they reflect buildings’ benefit to marginal buyers, thereby taking account of all available information on future market development. Prices that do not reflect available information may lead to over- or undersupply if developers react to these inefficient prices. In this study, we examine the efficiency of the UK commercial property market and the interaction between prices, construction costs, and new supply. We collated a unique data set covering the years 1920 onwards, which we employ in our study. First, we assess if real estate prices were in accordance with present values, thereby testing for informational efficiency. By comparing prices and estimated present values, we can measure informational inefficiency. Second, we assess if developers reacted correctly to price signals. Development (or the lack thereof) should be triggered by deviations between present values and cost; if prices do not reflect present values, then they should have no impact on development decisions.

Earlier studies have documented that foreign banks charge lower lending rates and interest spreads than domestic banks. We hypothesize that this may stem from the superior efficiency of foreign entrants that they decide to pass onto borrowers (“performance hypothesis”), but could also reflect a different loan allocation with respect to borrower transparency, loan maturity and currency (“portfolio composition hypothesis”). We are able to differentiate between the above hypotheses thanks to a novel dataset containing detailed bank-specific information for the Polish banking industry. Our findings demonstrate that banks differ significantly in terms of portfolio composition and we attest to the “portfolio composition hypothesis” by showing that, having controlled for portfolio composition, there are no differences in lending rates between banks.

Im Zusammenhang mit der Positionierung von Städten und Gemeinden im Standortwettbewerb stellt sich die Frage, ob die existierenden kommunalen Verwaltungsstrukturen den damit verbundenen Anforderungen gerecht werden. Können etwa von den jüngst vom Land Sachsen-Anhalt eingeleiteten Gemeindegebietsreformen – mit dem Ziel einer stärker zentralisierten Verwaltungsstruktur – eine Steigerung der Wirtschaftlichkeit und Effizienz der kommunalen Leistungserstellung erwartet werden?

Die Theorie des fiskalischen Föderalismus und die neue Institutionenökonomik lassen keine eindeutigen Rückschlüsse auf die Vorteilhaftigkeit zentralisierter Gemeindestrukturen zu. Die hier präsentierten Ergebnisse einer Querschnittsanalyse (Mittelwertvergleich, Regressionsanalyse) der Ausgaben und des Personalbestands für verschiedene Aufgabenbereiche aller kreisangehörigen Gemeinden in Sachsen-Anhalt bestätigen dies: Signifikante Kostenvorteile der Einheitsgemeinden gegenüber den Verwaltungsgemeinschaften, d. h. von zentralisierten im Vergleich zu eher dezentral organisierten Verwaltungsformen, konnten nicht belegt werden. Mit Ausnahme des eher trivialen der höheren Ausgaben für Gemeinderäte und Bürgermeister in Verwaltungsgemeinschaften sind die festgestellten Kostenunterschiede in nicht unerheblichem Maß auf Unterschiede in der Siedlungsstruktur und weniger auf die Verwaltungsform zurückzuführen.

Selbst bei einer Beschränkung auf die reinen Bereitstellungskosten kommunaler Leistungen kann daher eine radikale Konzentration der sachsen-anhaltischen Gemeinden nicht befürwortet werden. Dies gilt umso mehr, wenn außerdem noch die nur schwer quantifizierbaren und mit dem Zentralisierungsgrad der kommunalen Ebene zunehmenden „Frustrationskosten“ sowie die Sanktions- und Kontrollkosten der Bürger berücksichtigt würden.

In this paper we study interdependencies between corporate foreign investment and the capital structure of banks. By committing to invest predominantly at home, firms can reduce the credit default risk of their lending banks. Therefore, banks can refinance loans to a larger extent through deposits thereby reducing firms’ effective financing costs. Firms thus have an incentive to allocate resources inefficiently as they then save on financing costs. We argue that imposing minimum capital adequacy for banks can eliminate this incentive by putting a lower bound on financing costs. However, the Basel II framework is shown to miss this potential.

Economic theory knows two systems of coordination: through public choice or through the market principle. If the market is chosen, then it may either be regulated, or it may be fully competitive (or be in between these two extremes). This paper first inquires into the reasons for regulation, it analyses the reasons for the important role of government in the transportation sector, especially in the procurement of infrastructure. Historical reasons are seen as important reasons for bureaucratic objections to deregulation. Fundamental economic concepts are forwarded that suggest market failure and justify a regulatory environment. The reasons for regulation cited above, however, may be challenged; we forward theoretical concepts from industrial organization theory and from institutional economics which suggest that competition is even possible on the level of infrastructure. The transition from a strongly regulated to a competitive environment poses problems that have given lieu to numerous failures in privatization and deregulation. Structural inertia plays an important role, and the incentive-compatible management of infrastructure is seen as the key element of any liberal transportation policy. It requires that the setting of rules on the meta level satisfies both local and global efficiency ends. We conclude that, in market economies, competition and regulation should not be substitutes but complements. General rules, an "ethic of competition" have to be set that guarantee a level playing field to agents; it is complimented by institutions that provide arbitration in case of misconduct.
