Attribute Dependence and the Provision of Quality

Regional Science and Urban Economics,
Nr. 5,
2001
Abstract
Often a quality improvement necessitates modifications of varietal product features. This paper studies firms’ incentives to provide quality when this decision affects the goods’ degree of perceived horizontal differentiation. We find that the quality level hinges crucially on the interaction between the quality and the varietal product attribute. We examine the outcome of a game where firms decide on quality and price relative to what a social planner would desire. If the interaction between quality and perceived horizontal differentiation is sufficiently positive, we find for the sequential game ‘quality then price’ that the private incentives to provide quality are excessive relative to the social optimum. As a result the level and the direction of interaction between the attributes determines whether there is excessive or insufficient provision of quality.

Price Competition between an Expert and a Non-Expert
Jan Bouckaert, Hans Degryse
International Journal of Industrial Organization,
Nr. 6,
2000
Abstract
This paper characterizes price competition between an expert and a non-expert. In contrast with the expert, the non-expert's repair technology is not always successful. Consumers visit the expert after experiencing an unsuccessful match at the non-expert. This re-entry affects the behavior of both sellers. For low enough probability of successful repair at the non-expert, all consumers first visit the non-expert, and a 'timid-pricing' equilibrium results. If the non-expert's repair technology performs well enough, it pays for some consumers to disregard the non-expert a visit. They directly go to the expert's shop, and an 'aggressive-pricing' equilibrium pops up. For intermediate values of the non-expert's successful repair a 'mixed-pricing' equilibrium emerges where the expert randomizes over the monopoly price and some lower price.

The Total Cost of Trading Belgian Shares: Brussels versus London
Hans Degryse
Journal of Banking and Finance,
Nr. 9,
1999
Abstract
Since 1990, London’s SEAQ International (SEAQ-I) has attracted considerable trading volume in Belgian equities. This paper investigates competition between the Brussels CATS market and London’s SEAQ-I. Toward this end, we gathered extensive limit order book data as well as transactions and quotation information. With regard to liquidity (indirect costs), measured by the quoted and effective bid–ask spread, the paper concludes that CATS outperforms SEAQ International for both measures. The effective spread is of course substantially smaller than the quoted spread, with the CATS effective spread showing a U-shaped form. This paper, unique in employing an extensive data set that includes all hidden orders and the whole limit order book, produces results in line with the different market microstructure models. Total trading costs on CATS are lower (higher) for small (large) trade sizes.

Makroökonomische Faktoren und mikroökonomische Risiken von Banken
Claudia M. Buch, S. Eickmeier, Esteban Prieto
Ökonomenstimme,
2010
Abstract
Die jüngste Finanz- und Wirtschaftskrise hat gezeigt, dass Entwicklungen im Bankensektor und makroökonomische Entwicklungen oftmals sehr eng miteinander verwoben sind. Banken reagieren auf eine expansive Geldpolitik, in dem sie ihre Kreditvergabe ausweiten und dabei unter Umständen höhere Risiken eingehen; umgekehrt reagiert die Geldpolitik auf Liquiditätsengpässe im Bankensektor, in dem sie zusätzliche Liquidität bereitstellt. Diese und andere Anpassungsmuster spielen sich aber nicht nur auf aggregierter Ebene ab; vielmehr liegen ihnen eine Vielzahl von zum Teil sehr unterschiedlichen Anpassungsmustern auf der Ebene der einzelnen Bank zu Grunde. Banken unterscheiden sich beispielsweise im Grad ihrer Abhängigkeit der Refinanzierung über den Interbankenmarkt, sie sind in ihrem Geschäft Zinsänderungsrisiken in unterschiedlichem Ausmaß aufgesetzt, und sie sind unterschiedlich stark im Ausland engagiert und damit von makroökonomischen Entwicklungen im Inland abhängig.

Quality of Service, Efficiency, and Scale in Network Industries: An Analysis of European Electricity Distribution
Christian Growitsch, Tooraj Jamasb, Michael Pollitt
IWH Discussion Papers,
Nr. 3,
2005
Abstract
Quality of service is of major economic significance in natural monopoly infrastructure industries and is increasingly addressed in regulatory schemes. However, this important aspect is generally not reflected in efficiency analysis of these industries. In this paper we present an efficiency analysis of electricity distribution networks using a sample of about 500 electricity distribution utilities from seven European countries. We apply the stochastic frontier analysis (SFA) method on multi-output translog input distance function models to estimate cost and scale efficiency with and without incorporating quality of service. We show that introducing the quality dimension into the analysis affects estimated efficiency significantly. In contrast to previous research, smaller utilities seem to indicate lower technical efficiency when incorporating quality. We also show that incorporating quality of service does not alter scale economy measures. Our results emphasise that quality of service should be an integrated part of efficiency analysis and incentive regulation regimes, as well as in the economic review of market concentration in regulated natural monopolies.

Inflation and Relative Price Variability in the Euro Area: Evidence from a Panel Threshold Model
Dieter Nautz, Juliane Scharff
Applied Economics,
Nr. 4,
2012
Abstract
The impact of inflation on Relative Price Variability (RPV) generates an important channel for real effects of inflation. This article provides first evidence on the empirical relation between inflation and RPV in the euro area. Stirred by the widespread use of inflation caps or target bands in monetary policy practice, we are particularly interested in threshold effects of inflation. In line with the predictions of monetary search models, our results indicate that expected inflation significantly increases RPV only if inflation is either very low (below 0.95% per annum (p.a.)) or very high (above 4.96% p.a.).

An analysis of household electricity price developments in Germany since liberalization
Christian Growitsch, Felix Müsgens
Externe Publikationen,
2005
Abstract
Despite the liberalization of energy markets in 1998, household electricity prices in 2004 are nearly the same as 1998, indicating a failure of market restructuring. However, such a general consideration is misleading for two main reasons. Firstly, the price development shows significant differences among the stages of the value chain. Secondly, the underlying cost structure might have changed from 1998 to 2004. While such effects can be expected to level out over time, they can distort the comparison of a small period of observation. For these reasons, we analyzed the different price components at a detailed level, finding a considerable price reduction of about 32% in generation and a much lower reduction of 13% in transmission and distribution tariffs. These decreases have been mostly compensated by a significant increase in taxes and subsidies (+56%).

Regulation, Innovation and Technology Diffusion - Evidence from Building Energy E fficiency Standards in Germany

Discussionpapers des DIW Berlin,
Nr. 1371,
2014
Abstract
The impact of environmental regulation on technology diffusion and innovations is studied using a unique data set of German residential buildings. We analyze how energy effi ciency regulations, in terms of minimum standards, affects energy-use in newly constructed buildings and how it induces innovation in the residential-building industry. The data used consists of a large sample of German apartment houses built between 1950 and 2005. Based on this information, we determine their real energy requirements from energy performance certificates and energy billing information. We develop a new measure for regulation intensity and apply a panel-error-correction regression model to energy requirements of low and high quality housing. Our findings suggest that regulation significantly impacts technology adoption in low quality housing. This, in turn, induces improvements in the high quality segment where innovators respond to market signals.

Gemeindegröße, Verwaltungsstruktur und Wahlbeteiligung: Auswirkungen der Kommunalreform auf die Legitimation politischer Entscheidungsprozesse
Martin T. W. Rosenfeld, Claus Michelsen
Gebiets- und Verwaltungsstrukturen im Umbruch: Beiträge zur Reformdiskussion aus Erfahrungen in Sachsen, Sachsen-Anhalt und Thüringen,
Nr. 360,
2015
Abstract
In der politischen Diskussion wird immer wieder gefordert, die Gemeinden von ihrem Gebietszuschnitt her zu vergrößern und auf eine verwaltungsmäßige interne Untergliederung der kommunalen Einheiten zu verzichten, mithin das Modell der sogenannten Einheitsgemeinden und nicht jenes der föderativ verfassten Gemeinden zu verwirklichen. Dabei werden die „Kosten“ im Sinne von volkswirtschaftlichen Nachteilen dieses zentralistischen Modells zumeist nur am Rande erwähnt, was nicht zuletzt den Problemen der Quantifizierbarkeit dieser Kosten geschuldet ist. Der Beitrag unternimmt den Versuch einer entsprechenden Quantifizierung für einen Teilaspekt der volkswirtschaftlichen Nachteile von größeren und stärker zentralisierten kommunalen Einheiten, nämlich deren negativen Effekte auf die Höhe der Wahlbeteiligung. Im Ergebnis der empirischen Untersuchungen kann gezeigt werden, dass die theoretischen Vermutungen zutreffend sind, wonach (1.) die Wahl der Organisation kommunaler Verwaltungseinheiten Auswirkungen auf die Wahlbeteiligung hat, und (2.) der Organisationstyp der Einheitsgemeinden im Vergleich zu föderativ organisierten Gemeindetypen zu einer deutlich geringeren Wahlbeteiligung führt.
