The Distributional Effects of Public Expenditure

It is commonly agreed that economic policies, including budgetary policies, can have potentially strong distributional effects. Traditional economic analysis held that economic policies affected the income distribution primarily through their impact on the rate of growth. More recently, it has come to be recognised that qualitative aspects of economic growth are probably more important than the rate of growth itself. While recent research has confirmed the potential role of expenditure policies as a redistributive tool, it has also shown that redistribution does not necessarily have to come at the expense of economic growth and efficiency. Although there are substantial analytical and technical problems to be faced in the design of equitable and cost-effective public expenditure programmes, unfavourable distributional outcomes of these programmes can usually be traced more to political and institutional pressures than to purely technical factors.

Auctions with variable supply: Uniform price versus discriminatory

We examine an auction in which the seller determines the supply after observing the bids. We compare the uniform price and the discriminatory auction in a setting of supply uncertainty, where uncertainty is caused by the interplay of two factors: the seller's private information about marginal cost and the seller's incentive to sell the profit-maximizing quantity, given the received bids. In every symmetric mixed strategy equilibrium, bidders submit higher bids in the uniform price auction than in the discriminatory auction. In the two-bidder case, this result extends to the set of rationalizable strategies. As a consequence, we find that the uniform price auction generates a higher expected revenue for the seller and a higher trade volume.     

Integrated ecological-economic modelling of water pollution abatement management options in the Upper Ems River Basin

This paper presents the results of the FLUMAGIS project, in which we developed a spatial decision support system (SDSS) to support the implementation of the European Water Framework Directive (WFD). The modelling approach is based on the integration of ecological and socio-economic assessment methods, scale-specific and GIS-based data and knowledge modelling and visualization techniques. The project study area is the intensively cropped Upper Ems River Basin in north-western Germany. A method was developed that enables the transfer of scale-specific data and information. Analyses were performed for baseline conditions and specific management and planning scenarios to improve water quantity and quality at micro-, meso- and macro-scale. The results of the study indicate that substantial, expensive water and land management changes at different scales would be necessary to achieve the WFD water quality targets in this basin. Ecological-economic analysis of cost-effectiveness reveals that the costs of achieving certain goals of the WFD can vary more than tenfold depending on which measure is chosen out of the pool of management alternatives. Moreover, the study shows that the differentiation between landscapes and other regional characteristics although considered essential to the successful implementation of WFD measures is very data intensive.

The impact of the EC’s agricultural policy on its trade with developing countries

The European Community has frequently been blamed for impairing, through its highly protectionist agricultural policy, the development chances of Third World countries. Our article analyses whether, and to what extent, this reproach is justified.     

The prospects of energy conservation: A different approach to the fuel demand for space heating

Zusammenfassung Die meisten empirischen Untersuchungen über das Ausmaß der jüngsten Energieeinsparungen verwendeten ökonometrische Beziehungen und Elastizitäten. Diese Arbeit jedoch geht von einer technischen Beschreibung des Services thermische Behaglichkeit aus. Basierend auf empirischem Datenmaterial über die Infrastruktur und das Klima der Stadt Wien werden sowohl die Aussichten und das Potential an Energieeinsparungen quantifiziert als auch der Effekt spezifischer Politiken. Für diesen Zweck wurde ein nichtlineares Optimierungsmodell mit disjunktiven Randbedingungen entwickelt und gelöst.

The domestic term structure and international interest rate linkages: A cointegration analysis

The Domestic Term Structure and International Interest Rate Linkages. A Cointegration Analysis. -This paper analyzes cointegration relations between domestic interest rates with different maturities and between the US and German interest rates of the same maturity by means of the Johansen procedure and single-equation error correction models. It analyzes also the implied common stochastic trends. The author concludes that in the long run, interest spreads within both countries strongly dominate and linkages between the interest rates of both countries are only important in the short run.
