In this paper we are interested in the problem of comparisons with the best population. One case where comparisons with the best arise naturally is the measurement of productive efficiency.
The current research contributes to two areas that have attracted scarce research attention in Greece: the experimental investigation of housing discrimination and discrimination by ethnicity. The results of this study have implications for understanding some of the enduring patterns of ethnic discrimination in the housing market.
This paper extends the standard New Keynesian dynamic stochastic general equilibrium (DSGE) model to agents who cannot smooth consumption (i.e. spenders) and are affected by external consumption habits.
This paper studies the problem of a company which expands its stochastic production capacity in irreversible investments by purchasing capital and faces both fixed and proportional costs.
The current research contributes to the small academic literature on the economics of discrimination according to sexual orientation in Europe.
The purpose of the paper is twofold. Firstly, we test the validity of the PPP hypothesis for selected CEEC (Czech Republic; Hungary; Poland and Slovak Republic). Secondly, we attempt to define those countries' trade linkages between Euro Area; US and the rest of the world.
We study the construction of confidence intervals for efficiency levels of individual firms in stochastic frontier models with panel data.
We propose a generalized methods of moments procedure by which both the number of factors and the regression coefficients can be consistently estimated. Some important identification issues are also discussed. Our simulation results indicate that the proposed methods produce reliable estimates.
Many low skilled jobs have been substituted away for machines in Europe, or eliminated, much more so than in the US, while technological progress at the “top”, i.e. at the high-tech sector, is faster in the US than in Europe. This paper suggests that the main difference between Europe and the US in this respect is their different labor market policies
This paper studies firms owners' incentives to engage in Corporate Social Responsibility (CSR) activities in an oligopolistic market, in a strategic delegation and vertical product differentiation context.
This paper develops a tractable theoretical framework for analyzing the substitutability between different advertising media, the extent of marketing spillovers in the market, the allocative efficiency of advertising spending, and the sources of total advertising productivity and sales growth.
In this paper drawing from the theoretical framework developed by Shieh et al., (2002), we present an endogenous growth model to empirical analyze the growth maximizing allocation of public capital among military spending and investment in infrastructure.
Due to the assumption that the best practice methods refer to each input separately instead of the whole set of inputs used by a firm, the benchmark technology as defined in the stochastic varying coefficient frontier model may be infeasible and theoretically improper whenever the maximum response coefficients are not coming from the same production unit. To overcome this problem we suggest an alternative procedure for measuring output-oriented and input-specific technical efficiency inspired from the maximum likelihood formulation of the non-neutral frontier model.
This paper examines the validity of the purchasing power parity between each of the twelve new EU countries vis-à-vis the Eurozone.
In this study, we attempt to examine the possibility of emergence of significant fluctuations of the exchange rates in the future for the candidate EMU countries.
The paper investigates whether low skilled male Albanians face unequal treatment in the Greek labour market, two years after the national adoption of the European anti-discrimination employment legislation.
In this paper a broad list of different merger motives that has been proposed in the literature are analyzed and compared.
This paper studies the endogenous structure of incentive contracts that firms' owners offer to their managers, when these contracts are linear combinations either of own profits and own revenues, or of own profits and competitor's profits or, finally, of own profits and own market share.
This paper investigates the impact of alternative unionization structures on firms' incentives to spend on cost-reducing R&D activities as well as to form a Research Joint Venture, in the presence of R&D spillovers.
Our study sheds light on the issue of volatility forecasting under risk management environment and on the evaluation procedure of various risk models.
This paper sheds light on the importance of the validity of PPP hypothesis for the accessing process of the candidate countries towards EMU.
This paper is using simple nonlinearity tests to provide evidence of a positive and significant causal relationship going from stock market development to economic growth in Greece during the last 10 years.
