Bank Concentration and Retail Interest Rates

Abstract
The recent wave of mergers in the euro area raises the question whether the increase in concentration has offset the increase in competition in European banking through deregulation. We test this question by estimating a simple Cournot model of bank pricing. We construct country and product specific measures of bank concentration and find that for loans and demand deposits increasing concentration may have resulted in less competitive pricing by banks, whereas for savings and time deposits, the model is rejected, suggesting increases in contestability and/or efficiency in these markets. Finally, the paper discusses some implications for tests of the effect of concentration on monetary policy transmission.

Methods of estimating the overall economic production potential and the productivity gap

IWH Discussion Papers,
No. 142,

Abstract
Für die wirtschaftspolitischen Instanzen stellt die Kenntnis des Produktionspotentials und des daraus abgeleiteten gesamtwirtschaftlichen Kapazitätsauslastungsgrades eine wichtige Orientierungsgröße dar. In diesem Diskussionspapier werden verschiedene Methoden der Schätzung des Produktionspotentials dargestellt. Diese umfassen Unternehmensbefragungen, reine Zeitreihenmethoden und Verfahren, die explizit die ökonomische Theorie berücksichtigen. Hier ist insbesondere der Produktionsfunktions-Ansatz zu nennen. Abschließend werden einige der vorgestellten Schätzmethoden auf Daten der Bundesrepublik Deutschland angewandt.

The Effect of Expected Effective Corporate Tax Rates on Incremental Financing Decisions
Reint E. Gropp
IMF Staff Papers,
No. 4,
1997
Abstract
This paper uses U.S. panel data to estimate the effect of expected effective corporate tax rates on the amount of debt issued by firms. The paper directly estimates expected corporate tax rates using rational expectations. The estimated measures of expected effective tax rates of firms are related to a continuous measure of incremental debt financing. The paper finds that expected effective tax rates are significantly and positively related to a higher level of debt financing. Simulations suggest that debt issues would double if firms were unable to shield profits and actually faced the statutory tax rate.

Uncovered Workers in Plants Covered by Collective Bargaining: Who Are They and How Do They Fare?
Boris Hirsch, Philipp Lentge, Claus Schnabel
Abstract
In Germany, employers used to pay union members and non-members in a plant the same union wage in order to prevent workers from joining unions. Using recent administrative data, we investigate which workers in firms covered by collective bargaining agreements still individually benefit from these union agreements, which workers are not covered anymore, and what this means for their wages. We show that about 9 percent of workers in plants with collective agreements do not enjoy individual coverage (and thus the union wage) anymore. Econometric analyses with unconditional quantile regressions and firm-fixed-effects estimations demonstrate that not being individually covered by a collective agreement has serious wage implications for most workers. Low-wage non-union workers and those at low hierarchy levels particularly suffer since employers abstain from extending union wages to them in order to pay lower wages. This jeopardizes unions' goal of protecting all disadvantaged workers.
