Testing the convergence hypothesis for Greece

The question of whether there is a tendency for regional convergence has become a central topic for economic research. This paper considers the issue of convergence across Greek regions, following the theoretical basis of the neoclassical model of economic growth. Our analysis finds no evidence of convergence and supports the hypothesis of dualism across the southern and the northern parts of the country. © 1997 John Wiley & Sons, Ltd.     

How transparency affects investment-linked insurance products

Investment-linked insurance products exhibit a series of advantages versus direct investments, such as accumulation of retirement funds, tax benefits, and waiver of premiums in the case of disability. However, they are perceived as more complex and difficult compared to plain investments. Consequently, there is a need for disclosures, so that retail investors - insured can make well-informed decisions. Such disclosures have so far been uncoordinated. The EU has identified the need for uniform transparency rules in the packaged retail and insurance-based investment products market. The EU made an effort to enhance protection for investors - insured via a regulation effective in 2017. Such an effort is expected to restore retail investor confidence lost in the aftermath of the crisis. In this paper we attempt to quantify the effect of the existing transparency rules in the various member states to have an indication of what to expect as soon as the new uniform rules are implemented. We use customer satisfaction and trust so as to measure the effect of transparency. We find that increased transparency positively affects both measures.     

Electoral Thresholds as Coordination Devices

In this paper, we study one‐person–one‐vote parliamentary elections where voters care both about the winner of elections and about the composition of the parliament. Parties enter the parliament if and only if their vote share exceeds some predetermined threshold. We show that equilibria generically exist in which all parties obtain a non‐degenerate vote‐share and, perhaps more importantly, we show that the size of the electoral threshold acts as a coordination device, which crucially affects the win prospects of the Condorcet winner party. In particular, we argue that the win prospects of the Condorcet winner party decrease with the size of the entry threshold.     

The Baltic Dry Index: cyclicalities,forecasting and hedging strategies

The cyclical properties of the Baltic Dry Index (BDI) and their implications for forecasting performance are investigated. We find that changes in the BDI can lead to permanent shocks to trade of major exporting economies. In our forecasting exercise, we show that commodities and trigonometric regression can lead to improved predictions and then use our forecasting results to perform an investment exercise and to show how they can be used for improved risk management in the freight sector.     

Profit strategy of Greek banks: cross-subsidization and diversification versus complementarity

This study analyses the profit strategy employed by banks in Greece using dynamic panel data techniques and a data set which includes proprietary supervisory data covering the whole Greek commercial banking system from 2004 to 2011. We provide evidence that banks use interest- and non-interest income (non-II) as substitutes rather than complements, with non-II representing an indirect competition instrument by the more efficient banks used in place of direct competition with their peers through prices on loans and deposits. This behaviour is explained by further decomposing the non-II into the relatively stable fees component and the volatile trading income. Moreover, we provide evidence that the net-interest income is primarily affected by the banks’ market power and their operating costs, while more efficient banks exploit their core deposit base to lever their non-II. Finally, macroeconomic developments affect both income components, which are found to be procyclical with respect to economic activity. In particular, the two income components are affected differently from inflation implying that non-II provides a natural hedge against adverse effects from deflation on interest income.     

Economic efficiency of Greek retail SMEs in a period of high fluctuations in economic activity: a DEA approach

This study aims to analyse the economic efficiency of Greek small and medium retail enterprises before and after the crisis that started in 2008. Based on the Accounting Equation, we use Data Envelopment Analysis (DEA) to estimate variable returns of scale efficiency scores and to conclude on specific characteristics that efficient companies have, for example, on capital structure. Our results from the DEA application show a high degree of inefficiency. We found that SMEs on the islands are more efficient than those on the mainland and that SMEs in the cities are the least efficient. Size seems to be important, more so on the islands and on the mainland than in the cities. We conclude that companies should act more conservatively in terms of operating cost when the first signs of a recession appear. In addition, during a recession period, companies that have evidences that their operations will continue positively should strengthen their operations by raising more own capital. Finally, our study clarifies four issues: the efficiency of retail companies in a period of growth and a period of recession, focusing on SMEs that operate in different regions, connecting Accounting Equation and DEA and adding acid ratio as an output in our model.     

Economic impact assessment of mega infrastructure pipeline projects

The economic development features for the decades after the Second World War provide evidence that investments to new infrastructures are a key driver in strengthening the national economy and enhancing nation’s productivity, as it creates economic benefits and additional income. However, the decision for fund allocation and investments in mega infrastructure pipeline projects often must be made in conditions that are much more fraught with uncertainty. The key question in such decisions is if the economic impact caused by the new project could be able to essentially boost the economy by creating new jobs and generating new income on one hand; and which are the business sectors expected to archive the benefits of this investment. This article deals with the estimation of the mega infrastructure pipeline project economic effects in economy. The methodological framework is based on input–output approach providing quantitative estimations about the economic impact of the project in terms of new income and jobs. The numerical application deals with the assessment of a cross-border crude oil pipeline project, connecting the ports of Burgas (Bulgaria) and Alexandroupolis (Greece), establishing a new transportation corridor for the crude oil from Black Sea to Southeast Mediterranean.     

Leading indicators of non-performing loans in Greece: the information content of macro-, micro- and bank-specific variables

We examine the information content of a unique set of macroeconomic, bank-specific, market and credit registry variables as regards their ability to forecast non-performing loans using a panel data set of nine Greek banks. We distinguish between business, consumer and mortgage loans and investigate their differences with respect to their optimal predictors. The quasi-AIM approach (Carson et al. in Int J Forecast 27:923–941, 2010) is utilized in order to take into account heterogeneity across banks and minimize estimation uncertainty. In addition, we calculate a number of forecasting measures in order to take into account the policy makers’ preferences. We find that market variables, specifically the supermarket sales, confidence indices for the services and construction sector and the business sentiment index represent good forecasting variables for most categories of NPLs. In addition, industrial production is the optimal predictor for consumer NPLs and imports for business NPLs. Finally, bank-specific variables represent top-performing leading indicators for business NPLs. Our results have significant implications for stress-testing credit risk in a top-down manner and for supervisory and macro-prudential policy design.     

‘Optimal’ probabilistic and directional predictions of financial returns

This paper examines the probability of returns exceeding a threshold, extending earlier work of Christoffersen and Diebold (2006) on volatility dynamics and sign predictability. We find that the choice of the threshold matters and that a zero threshold (leading to sign predictions) does not lead to the largest probability response to changes in volatility dynamics. Under certain conditions there is a threshold that has maximum responsiveness to changes in volatility dynamics that leads to ‘optimal’ probabilistic predictions. We connect the evolution of volatility to probabilistic predictions and show that the volatility ratio is the crucial variable in this context. The overall results strengthen the arguments in favor of accurate volatility measurement and prediction, as volatility dynamics are integrated into the ‘optimal’ threshold. We illustrate our findings using daily and monthly data for the S&P500 index.     

Ecotourism and sustainability in Mediterranean islands

Sustainable and ecotourism practices in the Mediterranean islands are still at their infancy stage. Over recent years, there has been an increased awareness about these types of practices, mainly expressed in the form of agreements and declarations. Although ecotourism practices have been applied in some islands, there are no instances where it has enjoyed popular demand among consumers. Most of the ecotourists who visit the Mediterranean islands tend to be of an occasional nature in that they are engaged in other forms of tourism in addition to ecotourism. The purpose of this paper is to review the current sustainable and ecotourism practices in selected islands in the Mediterranean (Balearic Islands, Crete, and Vis), as well as the environmental trends that are occurring within tourism in this region. © 2000 John Wiley & Sons, Inc.
