Competition Policy in Network Industries, INFER Research Perspectives, Vol. 3,
2007
Abstract
The paper investigates the effects of several characteristics of regulatory frameworks in the water sector on the efficiency of water provision. Several requirements on efficient regulatory frameworks suggested in other studies of network industries are modified and others are derived from different economic theories of regulation. The resulting set of criteria is applied to the regulation systems of the Dutch, German and US-American water industry. A comparison of several performance indicators for the three countries suggests that some relationship between the design of regulatory frameworks and the price-quality-ratios in the water sector might exist.

Exploring the International Linkages of the Euro Area: A Global VAR Analysis
Stéphane Dées, Filippo di Mauro, M. Hashem Pesaran, Vanessa Smith
Journal of Applied Econometrics,
No. 1,
2007
Abstract
Abstract This paper presents a quarterly global model combining individual country vector error-correcting models in which the domestic variables are related to the country-specific foreign variables. The global VAR (GVAR) model is estimated for 26 countries, the euro area being treated as a single economy, over the period 1979?2003. It advances research in this area in a number of directions. In particular, it provides a theoretical framework where the GVAR is derived as an approximation to a global unobserved common factor model. Using average pair-wise cross-section error correlations, the GVAR approach is shown to be quite effective in dealing with the common factor interdependencies and international co-movements of business cycles. It develops a sieve bootstrap procedure for simulation of the GVAR as a whole, which is then used in testing the structural stability of the parameters, and for establishing bootstrap confidence bounds for the impulse responses. Finally, in addition to generalized impulse responses, the current paper considers the use of the GVAR for ?structural? impulse response analysis with focus on external shocks for the euro area economy, particularly in response to shocks to the US.

The Loss Distribution of the Entrepreneurial Bad Debt Risk – a Simulation-based Model
Henry Dannenberg
IWH Discussion Papers,
No. 10,
2006
Abstract
The risk of bad debt losses evolves for companies which grant payment targets. Possible losses have to be covered by these companies equity and liquidity reserves. The question of how to quantify the level of risk of bad debt losses will be discussed in this paper. Input values of this risk are the probability of default, exposure at default and loss given default. It is shown how companies can derive probability functions to describe uncertainty and variability for each input value. Based on these probability functions a simulation model is developed to quantify the risk of bad debt losses. Based on an empirical study probability functions for probability of default and loss given default are presented.

A Monetary Vector Error Correction Model of the Euro Area and Implications for Monetary Policy
Oliver Holtemöller
Empirical Economics,
No. 3,
2004
Abstract
In this paper, a vector error correction model for Euro area money, prices, output, long-term interest rate and short-term interest rate with three identified cointegration relations is specified. It is shown that Euro area money and prices can be considered as variables that are integrated of order two or I(2), that is, they have to be differenced twice to become stationary. Accordingly, the relation between money, prices and other macroeconomic variables is analyzed in an econometric framework which is suited for the analysis of I(2)-variables. Monetary policy implications are derived from the estimated system.

Business services in East Germany - an update
Siegfried Beer
Wirtschaft im Wandel,
No. 8,
2004
Abstract
The article presents the results of the German service sector statistic 2001 for company oriented services in the New Länder (without Berlin), which have been derived from data of the regional statistical offices. The article can be regarded as an update of an earlier version (see “Wirtschaft im Wandel”, 12/2003, p.342-349). Fundamental results are: 1. Compared to 2000, the New Länder’s proportion of Germany’s total revenue and employment in company oriented services has, compared to 2000, slightly increased, but remains rather small. 2. The profitability of East German companies has deteriorated, measured by total expenses per sales unit. Partially this might be due to the increased number of businesses. 3. Last evaluation’s assumption, that East German company’s labor productivity (gross value added per employees) is half of the West German’s, has been proofed in this actual evaluation. An illustration of reasons is not being provided since it has been discussed extensively in the first evaluation.

Firm-Specific Determinants of Productivity Gaps between East and West German Industrial Branches
Johannes Stephan, Karin Szalai
IWH Discussion Papers,
No. 183,
2003
Abstract
Industrial productivity levels of formerly socialist economies in Central East Europe (including East Germany) are considerably lower than in the more mature Western economies. This research aims at assessing the reasons for lower productivities at the firm level: what are the firm-specific determinants of productivity gaps. To assess this, we have conducted an extensive field study and focussed on a selection of two important manufacturing industries, namely machinery manufacturers and furniture manufacturers, and on the construction industry. Using the data generated in field work, we test a set of determinant-candidates which were derived from theory and prior research in that topic. Our analysis uses the simplest version of the matched-pair approach, in which first hypothesis about relevant productivity level-determinants are tested. In a second step, positively tested hypothesis are further assessed in terms of whether they also constitute firm-specific determinants of the apparent gaps between the firms in our Eastern and such in our Western panels. Our results suggest that the quality of human capital plays an important role in all three industrial branches assessed. Amongst manufacturing firms, networking activities and the use of modern technologies for communication are important reasons for the lower levels of labour productivity in the East. The intensity of long-term strategic planning on behalf of the management turned out to be relevant only for machinery manufacturers. Product and process innovations unexpectedly exhibit an ambiguous picture, as did the extent of specialisation on a small number of products in the firms’ portfolio and the intensity of competition.

A macroeconometric model for the Euro economy
Christian Dreger
IWH Discussion Papers,
No. 181,
2003
Abstract
In this paper a structural macroeconometric model for the Eurozone is presented. In opposite to the multi country modelling approach, the model relies on aggregate data on the supra-national level. Due to nonstationarity, all equations are estimated in an error correction form. The cointegrating relations are derived jointly with the short-run dynamics, avoiding the finite sample bias of the two step Engle Granger procedure. The validity of the aggregated approach is confirmed by out-of-sample forecasts and two simulation exercises. In particular the implications of a lower economic recovery in the US and a shock in the nominal Euro area interest rate are discussed.

Vierteljährliche Entstehungsrechnung des Bruttoinlandsprodukts für Ostdeutschland: Sektorale Bruttowertschöpfung
Hans-Ulrich Brautzsch, Udo Ludwig
IWH Discussion Papers,
No. 164,
2002
Abstract
Data regarding the development of macroeconomic production and employment are essential for the political decision process. Especially timely available information is a critical issue. Reliable short run data are not reported for East Germany yet. Because of data limitations for the past quarterly sectoral series of production and employment are derived from annual national accounts data using a set of indicators by branches. Indicators have been tested and cover working hours and sales, among others. For the period from 1992 to 2001 quarterly series for sectoral GDP are derived. A flash estimator for the overall macroeconomic performance is obtained through aggregation.

Labor Market Analysis and Public Policy: The Case of Morocco
Guillermo Hakim, Julia Lane, Javier Miranda
World Bank Economic Review,
No. 3,
1999
Abstract
This article uses detailed industry and household data to understand why Morocco's labor market performed poorly in 1985–95. The data indicate that marked structural changes and weak demand in the product market were responsible. This article makes two contributions to the literature. The first is specific: it underscores that the demand for labor is a derived demand and that the performance of the product market is an important determinant of the performance of the labor market. The second is more general: it demonstrates that this kind of microeconomic analysis, using data sets that are often available in developing countries, can inform policy design.
