Measurement Matters — Alternative Input Price Proxies for Bank Efficiency Analyses

Abstract
Most bank efficiency studies that use stochastic frontier analysis (SFA) employ each bank’s own implicit input price when estimating efficient frontiers. But at the same time, most studies are based on cost and/or profit models that assume perfect input markets. Traditional input price proxies therefore contain at least substantial measurement error. We suggest here two alternative input market definitions to approximate exogenous input prices. We have access to Bundesbank data, which allows us to cover virtually all German universal banks between 1993 and 2003. The use of alternative input price proxies leads to mean cost efficiency that is significantly five percentage points lower compared to traditional input prices. Mean profit efficiency is hardly affected. Across models, small cooperative banks located in large western states perform best while large banks and those located in eastern states rank lowest.

Evolving Structural Patterns in the Enlarging European Division of Labour: Sectoral and Branch Specialisation and the Potentials for Closing the Productivity Gap

No. 5,

Abstract
This report summarises the results generated in empirical analysis within a larger EU 5th FP RTD-project on the determinants of productivity gaps between the current EU-15 and accession states in Central East Europe. The focus of research in this part of the project is on sectoral specialisation patterns emerging as a result of intensifying integration between the current EU and a selection of six newly acceding economies, namely Estonia, Poland, the Czech and Slovak Republics, Hungary and Slovenia. The research-leading question is concerned with the role played by the respective specialisation patterns for (i) the explanation of observed productivity gaps and for (ii) the projection of future potentials of productivity growth in Central East Europe.
For the aggregated level, analysis determines the share of national productivity gaps accountable to acceding countries’ particular sectoral patterns, and their role for aggregate productivity growth: in Poland, the Slovak Republic and Hungary, sectoral shares of national productivity gaps are considerable and might evolve into a ‘barrier’ to productivity catch-up.Moreover, past productivity growth was dominated by a downward adjustment in employment rather than structural change. With the industrial sector of manufacturing having been identified as the main source of national productivity gaps and growth, the subsequent analysis focuses on the role of industrial specialisation patterns and develops an empirical model to project future productivity growth potentials. Each chapter closes with some policy conclusions.

Macroeconomic Modelling of the German Economy in the Framework of Euroland
Rüdiger Pohl, Heinz P. Galler

No. 11,
2002
Abstract
An attempt to develop a new macroeconometric model for Germany is confronted with several questions that range from the general rationality of such an approach to specific problems of an appropriate model structure. One important aspect of this discussion is the introduction of the Euro as a common currency of the European monetary union. This institutional change may result in structural breaks due to changing behavior of economic agents. In addition, the definition of the spatial unit that is appropriate for modelling becomes a problem. Additional problems come from the introduction of the European Single Market and the increasing international economic integration not only within the European union but also beyond its borders. And in the case of Germany, the unification of the West and the East demand special attention. Last but not least, the harmonization of national accounting for the member states of the European Union has to be dealt with. Thus, the introduction of the Euro as a common currency is just one problem besides others that must be addressed.

State and development of municipal investment budgets in the New Länder considering business infrastructures; Experts report ordered by the Federal Economics Ministry
Martin Snelting, Christian Schumacher, Walter Komar, Peter Franz
IWH-Sonderhefte,
No. 3,
1998
Abstract
In der Studie werden die Entwicklung und Bestimmungsgründe kommunaler Investitionshaushalte in den neuen Ländern untersucht. Angebotsbezogene ökonometrische Schätzungen zeigen, dass kommunale Infrastrukturinvestitionen die Produktivität der ostdeutschen Unternehmen positiv beeinflusst haben. Simulationen mit einem Input-Output-Modell weisen zudem positive Nachfrageeffekte für Produktion und Beschäfti-gung aus, deren Dauerhaftigkeit aber vorsichtig zu bewerten ist. Auf der Basis von Be-fragungen und weitergehender Analysen werden aktuelle Infrastrukturdefizite aufge-zeigt sowie Empfehlungen für die künftige Infrastrukturpolitik unterbreitet.

Capital stock and demographic component – How can state pension insurance be reformed?
Christian Dreger, Jürgen Kolb
Wirtschaft im Wandel,
No. 13,
1997
Abstract
Der Artikel untersucht die Produktions- und Beschäftigungswirkungen alternativer Reformoptionen zur Finanzierung der gesetzlichen Rentenversicherung. Diskutiert werden die Erweiterung der Rentenformel um eine demographische Komponente und die Bildung eines steuerfinanzierten Teilkapitalstocks als Ergänzung zum Umlageverfahren. Kurzfristig verursacht der Aufbau des Kapitalstocks Belastungen. Langfristig überwiegen jedoch die expansiven Effekte, weil die ansonsten notwendigen Beitragssteigerungen unterbleiben.
