Supply-Driven Input-Output Multipliers

The paper raises and discusses issues related to the derivation, behaviour and characteristics of input-output multipliers where the exogenous changes are not assumed in elements of final demand but in total outputs of sectors and commodities. These multipliers are more appropriate for use in impact analysis of policies which influence farm outputs, than the traditional final demand multipliers. The paper estimates also such “supply-driven” multipliers for 16 farm commodities of US agriculture. The empirical analysis shows that despite the variability in the multipliers' values, two rather solid groups of commodities which feel the strongest impacts of different crop and livestock output changes respectively, can be found. Several commodities are common to both groups, verifying also the significance of some indirect linkages between farm and non-farm commodities. However, the final demand sectors absorb the largest part of the initial exogenous change itself.     

Did the euro give us a break in inflation?

The introduction of the euro was accompanied by promises of lower inflation rates; however, the public feels that inflation increased when the euro was introduced. Officials admit that certain sectors experienced substantial price increases, but they claim that the overall inflation rate did not increase. This paper investigates whether inflation in 15 European countries experienced a structural break after the euro was introduced using new powerful and serial correlation robust test statistics. We find evidence that the European Monetary Union (EMU) countries experienced a positive break in inflation after 1999. Our results demonstrate that inflation just after the introduction of the euro was higher relative to the inflation just prior to the introduction of the euro. Additionally, we find no evidence of positive breaks for the non-EMU countries when the euro was introduced.     

Chained,exact and superlative hedonic price changes: estimates from microdata

Scanner data are used to calculate chained, exact (and superlative) hedonic price indexes for television sets. The data source is available for a wide range of goods, the application providing an example of how this method can be more widely applied. The indexes correspond to constant utility, hedonic cost-of-living indexes. The approach improves on the existing direct method, which takes its estimates directly from the coefficients on time dummies in a hedonic regression. It also improves on the matched model method used by statistical agencies. The differences between actual price changes and exact hedonic quality-adjusted price changes are found to be substantial. Base-period and current-period weighted exact hedonic indexes are similar, thus providing good approximations to a superlative index. Estimates from the direct, dummy variable approach were compared to the superlative indexes. The disparities between the results argue for caution in the use of the direct, dummy variable approach to estimating quality-adjusted price changes.     

Accountability and fiscal equalization

A common feature of multi-jurisdictional systems is equalization programs. The implementation of such programs, that is based on some measurement of sub-national fiscal capacity and effort, is particularly complex. Within a political economy model, this paper analyzes the impact of such systems on accountability, identifying a positive and a negative effect. The positive effect arises because with equalized fiscal resources, a consequence of equalization, citizens attach more importance to any remaining variation in public good supplies and so punish rent-taking more severely. This induces politicians to restrain themselves and so accountability improves. The negative effect arises because the complexity of such programs reduces the informational content of observed public good supplies. This introduces a perverse fiscal incentive that reduces accountability. Thus, the overall impact of equalization programs on accountability depends on the balance of these effects.     

Innovation diffusion with generation substitution effects

Markets of high technology products and services, such as telecommunications, are described by fast technological changes and rapid generational substitutions. Since the conventional modeling approaches that are based on diffusion models do not usually incorporate this important aspect into their formulations, the accuracy of the provided forecasts is consequently affected. The work presented in this paper is concerned with the development of a methodology for describing innovation diffusion, in the context of generation substitution. For this purpose, a dynamic diffusion model is developed and evaluated, based on the assumption that the saturation level of the market does not remain constant throughout the diffusion process but is affected by the diffusion of its descendant generation, as soon as the latter is introduced into the market. In contradiction to the conventional diffusion models, which assume static saturation levels, the proposed approach incorporates the effects of generation substitution and develops a diffusion model with a dynamic ceiling. The importance of such an approach is especially significant for markets characterized by rapid technological and generational changes. Evaluation of the proposed methodology was performed over 2G and 3G historical data and for a number of European countries, providing quite accurate estimation and forecasting results, along with important information regarding the rate of generation substitution.     

The Role of Location as a Selection Criterion in FDI: The Case of SMEs in Greece

The study examines the internationalization of Greek SMEs in Western Europe and the Balkan area, focusing on the role of location as a selection criterion in their FDI decisions. Data aimed at capturing SMEs’ perceptions with regard to incentives affecting their FDI based on location criteria. We find that location plays a significant role with regard to the benefits that firms gain, highlighting OLI paradigm's theoretical relevance in the examination of FDI, while presenting internationalization trends in the global environment. Findings further contribute to the adaption of effective practices to enhance firms’ competitiveness through more rational and targeted investment decisions.     

An Integrated System Supporting Virtual Consortia in the Construction Sector

Work in today's economic organizations is either performed through the execution of continuous operations or through the implementation of one-off projects; hence one can distinguish between "operation-centric" and "project-centric" business environments. New information and communication technologies facilitate the introduction of innovative organizational structures in both environments. Based on the term "virtual organization," which is used for describing the new organizational structures in operation-centric environments, we introduce the term "virtual consortium" for project-centric environments and provide an analysis of the business processes of a virtual consortium. We concentrate on the construction sector, as one of the most suitable application domains to test the new concept and related systems. Focusing on one of the most critical processes of a virtual consortium, the bidding/tendering process, we review the existing information systems available on the Internet, which support this process for construction projects. Our results show that although there are a substantial number of systems that support searching for call for tenders, few of them provide support for other vital elements of the bidding/tendering process, such as robust collaboration facilities for the virtual consortium formation and for the management of the bid. We then present the SupplyPoint system, which has been developed in order to electronically support and automate the whole tendering/bidding process of virtual consortia. SupplyPoint provides-in addition to what existing systems already do-a collaboration platform that facilitates, in a virtual manner, the formation of consortia.     

Institutions and financial dollarization: Indirect effects based on a policy experiment

We provide evidence that institutional improvements lead to lower levels of financial dollarization through previously unidentified channels. These indirect channels operate in addition to the direct impact identified in the literature and further illustrate the importance of institutions for the extent of banking dollarization.     

Discrimination and job search theories for black British young men

The paper examines empirically the relationship between government revenues and expenditures in four European countries: Greece, Spain, Ireland, and Portugal. In relative terms all four may be considered as the poorest members of the European Union. Yet, they present a fairly diverse picture as far as their macroeconomic performance and fiscal position is concerned. The empirical findings from cointegration and causality tests that are reported here indicate that in the case of Greece and Ireland tax and spending decisions are taken simultaneously by the fiscal authority, the tax-and-spend hypothesis is supported in the case of Spain, while absence of any causal ordering between government expenditure and tax revenues has been established for Portugal.
