This paper seeks to examine if the relative size of government (measured as the share of total expenditure in GNP can be determined to Granger cause the rate of economic growth, or if the rate of economic growth can be determined to Granger cause the relative size of government. For this purpose, we first use a bivariate error correction model within a Granger causality framework, as well as adding unemployment and inflation (separately) as explanatory variables, creating a simple 'trivariate' analysis for each of these two variables. The combined analysis of bivariate and trivariate tests offers a rich menu of possible causal patterns. Using data on Greece, UK and Ireland, the analysis shows: i) government size Granger causes economic growth in all countries of the sample in the short run and in the long run for Ireland and the UK; ii) economic growth Granger causes increases in the relative size of government in Greece, and, when inflation is included, in the UK.

This study investigates the long run relationship between government size and unemployment rate, the Abrams curve, using ten European countries over the period 1961-1999. To this end, panel cointegration analysis and estimation techniques appropriate for heterogeneous panels are made use of. The results support the idea that there is an Abrams curve, and the relation between government size and the unemployment rate is positive.
The paper studies technical inefficiency in the railway systems of ten countries of the European Union. A new approach is used which permits the disaggregation of inefficiency by factor of production to result in estimates of input-specific technical inefficiency. The cost structure is represented using a generalized McFadden flexible functional form. Policy implications and guidelines for rational decision making in the railway sector, are discussed in detail.
The purpose of this paper is to investigate the demand and its composition between home-produced and imported for alcoholic beverages in Cyprus. The methodological approach used is the Almost Ideal Demand System (AIDS), both in static and dynamic terms. Empirically, the AIDS, both in its static and dynamic version, was estimated using time-series (1970-1992) for three sets of data which include: (1) alcoholic beverages (wine-beer-other brandies) broken down between home-produced and imported (model A); (2) alcoholic beverages only without disaggregation between home-produced and imported (model B), and (3) aggregate alcoholic beverages (wine-beer-other brandies) and food (model C). Zellner's iterative estimation procedure was used for estimating the model. The empirical findings: (1) strongly support the dynamic version of the AIDS over its static alternative; and (2) provide certain guidelines concerning economic policies relating to an increase in government revenues and changing the composition between home-produced and imported consumption of alcoholic beverages. These basic findings could be considered relevant to the policy makers in the light of Cyprus' accession to the EU.
