An overview of corporate social responsibility in Greece: perceptions,developments and barriers to overcome

The objective of this paper is to provide an overview of corporate social responsibility (CSR) in Greece and present the challenges that need to be met in order to further promote socially responsible business behaviour in the domestic economy. This is the first attempt to provide a systematic analysis of CSR in Greece and adds to the existing pool of knowledge of CSR embeddedness in countries where CSR awareness is still rather low, a literature field that is still quite limited. Drawing from prior literature, the paper is built around three basic questions in relation to the Greek context: how is CSR perceived by Greek business professionals? How is CSR practised in Greece? And which issues evident in the modern domestic environment act as underlying barriers to the broader dissemination of CSR in Greece? The extant empirical work suggests that, while CSR in Greece appears to be developing, there is still scope for improvement and further diffusion of relevant practices. While some of the patterns shaping CSR in Greece have been analysed, much work still remains to be carried out in extending and deepening our knowledge in this part of Europe.     

Fostering enterprise architecture education and training with the enterprise architecture competence framework

Enterprise architecture (EA) implementation refers to a set of activities ultimately aiming to align business objectives with information technology infrastructure in an organization. EA implementation is a multidisciplinary, complicated and endless process, hence, calls for adequate education and training programs that will build highly skilled personnel (called enterprise architects) with diverse competencies. This development of domain‐specific competencies is also supported by European policies on education and vocational training. To this end, the authors present training uses of the Enterprise Architecture Competence Framework (EA‐CF). EA‐CF is a proposed conceptual model that describes EA competencies in compliance to the European e‐Competence Framework (e‐CF). The authors argue that EA stakeholders can consult the framework regarding competencies they want to underpin and thus identify the corresponding skills, knowledge and attitudes that result as learning outcomes in EA courses and training programs.     

The Effect of Cooperatives on Quality‐Enhancing Innovation

This paper develops game‐theoretic models of heterogeneous consumers to analyse the effect of cooperatives on quality‐enhancing product innovation activity, the pricing of food products and the welfare of the groups involved, in the context of a mixed duopoly where an open‐membership consumer co‐op competes with an investor‐owned firm in markets for horizontally differentiated products. Analytical results show that the involvement of the member welfare‐maximising co‐op in innovation activity can change the nature of product differentiation and the structure of the market, and be quality and welfare enhancing by increasing innovation activity and reducing the prices of food products. The effects of co‐operative involvement are shown to depend on the degree of consumer heterogeneity and the size of innovation costs.     

Assessing airport terminal performance using a system dynamics model

Current models for airport terminal performance assessment require substantial modeling effort to be customized to the configuration of a particular airport terminal and to reflect adequately the alternative airport operational policies adopted in a user-friendly way. Therefore, there is a need to develop a generic, yet flexible decision-support tool that will facilitate high-level decision-making related to fundamental changes in the structure and operation of the airport terminal system. This paper presents a generic and easily customizable system dynamics based tool for assessing the performance of the Athens International Airport passenger terminal under different demand and resource deployment scenaria.     

Airport slot allocation: a time for change?

The increasing imbalance between airport capacity and traffic resulted in exceptional congestion and delays drawing the attention of aviation policy makers towards airport demand management for the allocation of scarce airport slots. Attempts to bring forward airport demand management measures in the form of airport slot allocation were not widely adopted and have not flourished in practice. This paper aims: (i) to apply a methodological framework for the selection of the most suitable slot allocation strategy for various types of airports, (ii) to explore potential impacts such that measures or strategies can bring about, and (iii) to assess the suitability of the existing airport pricing scheme and the potential implementation of a new policy regime aiming to bridge the gap between growing traffic and scarce airport capacity.     

Minimum quality standard regulation under imperfect quality observability

Minimum quality standards (MQS) constitute an important regulatory tool that can be used to raise product qualities, to benefit consumers and to increase market participation. One of the main assumptions in the existing literature is that firms must comply with standards. Nevertheless, in many industries, and in particular the service industry, quality observability and enforceability are not perfect. Some low quality firms do not comply with standards. What are the welfare implications of an MQS regulation in such an environment? We develop a price competition model of vertical differentiation that accounts for these empirical observations. Contrary to well-established results in the literature, MQS can increase quality disparity between firms and raise hedonic prices. Some consumers get hurt and market participation decreases.     

Tax-spending policies and economic growth: Theoretical predictions and evidence from the OECD

We present an endogenous growth model to study the growth effects of the composition of government expenditure and the associated tax burden. When we use data from a set of 23 OECD countries during 1970–2000, our econometric results support the predictions of the theory. The share of productive government expenditure is associated with higher growth, and this result is more robust when we use effective average tax rates and statutory tax rates as measures of the tax burden. With respect to the tax burden, different tax rates have different growth effects.     

Product customization

The advent of the Internet has revolutionized the way companies advertise, develop and distribute products. Firms can now customize their advertising messages and products to the particular characteristics and needs of customers. Customers themselves can create their own products. We investigate investments by firms in product-customization capabilities within a duopoly model of horizontal product differentiation. We find that (i) if brand name effects are not too strong, one firm emerges as a leader in product customization—firms make asymmetric investments in product-customization technologies in order to reduce price competition, (ii) if brand name effects are strong, both firms make extensive investments in product customization, and (iii) the possibility of product customization can raise industry profits if brand names are weak, but not when they are strong.     

Sequential Monte Carlo for fractional stochastic volatility models

In this paper, we consider a fractional stochastic volatility model, that is a model in which the volatility may exhibit a long-range dependent or a rough/antipersistent behaviour. We propose a dynamic sequential Monte Carlo methodology that is applicable to both long memory and antipersistent processes in order to estimate the volatility as well as the unknown parameters of the model. We establish a central limit theorem for the state and parameter filters and we study asymptotic properties (consistency and asymptotic normality) for the filter. We illustrate our results with a simulation study and we apply our method to estimate the volatility and the parameters of a long-range dependent model for S& P 500 data.     

Non-myopic learning in differential information economies: the core

Summary. We study the process of learning in a differential information economy, with a continuum of states of nature that follow a Markov process. The economy extends over an infinite number of periods and we assume that the agents behave non-myopically, i.e., they discount the future. We adopt a new equilibrium concept, the non-myopic core. A realized agreement in each period generates information that changes the underlying structure in the economy. The results we obtain serve as an extension to the results in Koutsougeras and Yannelis (1999) in a setting where agents behave non-myopically. In particular, we examine the following two questions: 1) If we have a sequence of allocations that are in an approximate non-myopic core (we allow for bounded rationality), is it possible to find a subsequence that converges to a non-myopic core allocation in a limit full information economy? 2) Given a non-myopic core allocation in a limit full information economy can we find a sequence of approximate non-myopic core allocations that converges to that allocation?
