The East German Cement Cartel: Cartel Efficiency and Policy after Economic Transformation
Ulrich Blum
Eastern Economic Review,
2007
Abstract
In 2003 the German Antitrust Commission (GAC) proved the existence of a cartel in the German cement industry. The German cement producers involved in the case were fined € 661 million for having established quotas to extract additional rents. One of the main centers of this cartel was East Germany, where the East German Cement Combine with its giant facilities had been sold, in the early 1990s, to four large producers by Treuhand in the process of privatizing the economy. Only in respect to in this market did all defendants concede having had a part in forming a cartel.
In this paper, we challenge the argument of excess revenue that the GAC puts forward for the East German market. We argue that legal evidence does not necessarily translate into economic evidence. We show that demand for cement is realized in geographical and, to a more limited extent, in product space. Thus, in the absence of cartels we would expect monopolistic competition to prevail. We argue that any transition in the market regime, from the cartel to the post cartel period, must be traceable in the individual firm’s demand function which differs from the clients’ demand function because of costs for spatial and product differentiation. Within the framework of an econometric model, we cannot identify any structural changes in demand. Most likely, imports from Poland and the Czech Republic were dumped into the East German market and some medium sized producers were responsible for the cartel never working.
Finally the paper shows how difficult it is to generate competition in certain industries even under the umbrella of a well-established market economy, i.e. that of West Germany, and that the openness of the economy, i.e. trans-border shipments, are decisive.

Economies of Scope in European Railways: An Efficiency Analysis
Christian Growitsch, Heike Wetzel
IWH Discussion Papers,
No. 5,
2006
Abstract
In the course of railway reforms in the end of the last century, national European governments, as well the EU Commission, decided to open markets and to separate railway networks from train operations. Vertically integrated railway companies – companies owning a network and providing transport services – argue that such a separation of infrastructure and operations would diminish the advantages of vertical integration and would therefore not be suitable to raise economic welfare. In this paper, we conduct a pan-European analysis to investigate the performance of European railways with a particular focus on economies of vertical integration. We test the hypothesis that integrated railways realise economies of joint production and, thus, produce railway services on a higher level of efficiency. To determine whether joint or separate production is more efficient we apply a Data Envelopment Analysis super-efficiency bootstrapping model which relates the efficiency for integrated production to a virtual reference set consisting of the separated production technology. Our findings are that in a majority of European Railway companies exist economies of scope.

Optimale Geld- und Währungspolitik in Südafrika – Modellierung und Schätzung
Tobias Knedlik
Berichte der Internationalen Wissenschaftliche Vereinigung Weltwirtschaft und Weltpolitik e.V. Vol. 15,
No. 161,

Abstract
THE AIM OF THIS PAPER is to combine the estimation of the Monetary Conditions Index (MCI) with the theoretic modelling of monetary policy rules for open and emerging market economies using the example of South Africa. The idea that monetary policy is not only interested in optimal monetary conditions but also in external stability, constitutes the basis for the analysis. This idea emerged from studying currency crises that are caused by inadequate monetary policy and in particular from the experience of the Asian crisis of 1997/98 and its worldwide spread also to South Africa. The Monetary Conditions Index is a potentially useful tool for the development of monetary policy rules.

The integration of imperfect financial markets: Implications for business cycle volatility
Claudia M. Buch, C. Pierdzioch
Journal of Policy Modeling,
No. 7,
2005
Abstract
During the last two decades, the degree of openness of national financial systems has increased substantially. At the same time, asymmetries in information and other financial market frictions have remained prevalent. We study the implications of the opening up of national financial systems in the presence of financial market frictions for business cycle volatility. In our empirical analysis, we show that countries with more developed financial systems have lower business cycle volatility. Financial openness has no strong impact on business cycle volatility, in contrast. In our theoretical analysis, we study the implications of the opening up of national financial markets and of financial market frictions for business cycle volatility using a dynamic macroeconomic model of an open economy. We find that the implications of opening up national financial markets for business cycle volatility are largely unaffected by the presence of financial market frictions.

Financial Openness and Business Cycle Volatility
Claudia M. Buch, Jörg Döpke, C. Pierdzioch
Journal of International Money and Finance,
No. 5,
2005
Abstract
This paper discusses whether the integration of international financial markets affects business cycle volatility. In the framework of a new open economy macro-model, we show that the link between financial openness and business cycle volatility depends on the nature of the underlying shock. Empirical evidence supports this conclusion. Our results also show that the link between business cycle volatility and financial openness has not been stable over time.

Cross-border Banking and Transmission Mechanisms in Europe: Evidence from German Data
Claudia M. Buch
Applied Financial Economics,
No. 16,
2004
Abstract
International activities of commercial banks play a potential role for the transmission of shocks across countries. This paper presents stylized facts of the integration of European banking markets and analyses the potential of banks to transmit shocks across countries. Although the openness of banking systems has increased, bilateral financial linkages among EU countries are relatively small. The exceptions are claims of German banks on a number of smaller countries. These data are used for an analysis of the determinants of cross-border lending patterns.

The Impact of Technology and Regulation on the Geographical Scope of Banking
Hans Degryse, Steven Ongena
Oxford Review of Economic Policy,
No. 4,
2004
Abstract
We review how technological advances and changes in regulation may shape the (future) geographical scope of banking. We first review how both physical distance and the presence of borders currently affect bank lending conditions (loan pricing and credit availability) and market presence (branching and servicing). Next we discuss how technology and regulation have altered this impact and analyse the current state of the European banking sector. We discuss both theoretical contributions and empirical work and highlight open questions along the way. We draw three main lessons from the current theoretical and empirical literature: (i) bank lending to small businesses in Europe may be characterized both by (local) spatial pricing and resilient (regional and/or national) market segmentation; (ii) because of informational asymmetries in the retail market, bank mergers and acquisitions seem the optimal route of entering another market, long before cross-border servicing or direct entry are economically feasible; and (iii) current technological and regulatory developments may, to a large extent, remain impotent in further dismantling the various residual but mutually reinforcing frictions in the retail banking markets in Europe. We conclude the paper by offering pertinent policy recommendations based on these three lessons.

The effects of demographic changes on the level and structure of private consumption - a forecast for Germany until 2050 -
Harald Lehmann
IWH Discussion Papers,
No. 195,
2004
Abstract
This thesis analyzes the impact of different demografic scenarios on level and composition of private consumption in Germany. The analysis is based on the current household budget survey (Einkommens- und Verbrauchsstichprobe 1998) whose datas are adapted to the concepts of national accounting. Therefore households have to be defined by demografic aspects to investigate their consumption behavior. In the next step this will be used to forecast the effects of an aging population on private consumption by utilize a shift share analysis. The results lay open that the demografic impact is minor compared to economic factors influencing the composition of private consumption. This holds also in regard to the development of the absolute level of private consumption.

Competition Policy in Central Eastern Europe in the Light of EU Accession
Jens Hölscher
Journal of Common Market Studies,
No. 2,
2004
Abstract
This study reviews the progress made in EU accession candidates on competition policy. The analysis shows that institution-building and legislation are well under way and that anti-trust practice is not too lax. Due to the diversity among the accession countries under review, the study finds that the strictly rule-based frame work of the EU might not be the most favourable solution for some candidates: firstly, the small and open economies of most candidates make it particularly difficult to define the ‘relevant market’ in competition cases. Secondly, the traditionally intense vertical integration of production in accession states calls for a reassessment of ‘vertical restraints’. The policy implications of this study suggest that the EU competition task force should take a proactive, case-by-case approach vis-à-vis its new members.
