GARCH modelling of banking integration in the Eurozone

We investigate the progress of integration in the European banking industry and its effects on the price of the common stock of banks listed on European stock exchanges. We estimate the overall effect of progress by comparing the changes in the stock price volatility of listed banks over the period from January 1990 to December 2005. Using univariate and bivariate GARCH models, we document that the introduction of the Euro and the enlargement of the European Union in May 2004 have contributed to the integration process of the banking industry in Europe. We also find evidence of negative volatility spillovers among bank stock returns for different groups of countries that have been involved in various recent stages of the European economic and political integration.     

Assessing the Vulnerability to Price Spikes in Agricultural Commodity Markets

We examine empirically the predictability of conditions associated with a higher probability of a price spike in agricultural commodity markets. We find that the forward spread is the most significant indicator of probable price jumps in maize, wheat and soybeans futures markets, a result which is in line with the ‘Theory of Storage’. We additionally show that some option-implied variables add significant predictive power when added to the more standard information variable set. Overall, the estimated probabilities of large price increases from our probit models exhibit significant correlations with historical sudden market upheavals in agricultural markets.     

The spatial impact of EU Pan-European transport axes: City clusters formation in the Balkan area and developmental perspectives

This article explores the spatial and development implications of the Pan-European Transport Axes in the Balkans. For that purpose, the potential Development Poles and Axes are determined, on the basis of size, the location of cities, their interconnection and their role as hubs of the Pan-European axes. This is achieved by means of the formation and implementation of a methodology based on the use of special statistical applications. According to data analysis, three geographical units arise: Central Core, Peripheral Zone, Perimetric Zones. In the analysis that follows, Advantages, Weaknesses, Opportunities and Threats are examined in each case and suggestions are made as regards the policies required.     

Efficient Monetary Policy Design near Price Stability

Using dynamic programming methods, we study the design of optimal monetary policy in a simple, calibrated open-economy model and evaluate the effect of the liquidity trap generated by the zero bound on nominal interest rates. We show that the optimal policy near price stability is asymmetric. As inflation declines, policy turns expansionary sooner and more aggressively than would be optimal in the absence of the zero bound. This introduces an upward bias in the average level of inflation. We also discuss operational issues associated with the interpretation and implementation of policy at the zero bound in relation to the recent situation in Japan. J. Japan. Int.

The relationship between organizational culture and market orientation in the Greek telecommunication companies

The modern business environment is characterized by intense competition, which has led telecommunication companies to a continuous race towards gaining and maintaining a competitive advantage. In order to succeed, telecommunication companies “cultivate” market orientation and market oriented cultures as non-imitable characteristics, capable to ensure long–term corporate viability and growth. This paper provides an insight into the Greek telecommunication industry by: a) revealing the coordination between market orientation strategies with corresponding culture, b) the relationship between extrovert-type cultures with performance and c) how special traits of telecommunication providers (size and age) influence the degree of market orientation and the dominant culture type (introvert or extrovert). The paper contributes: a) to the creation of national cultural profile in the telecommunication industry, which can become a starting point in a wider trial to create a European industry profile, b) to the empirical testing of the correlation between culture and market orientation and c) to the examination of the extent to which background factors (such as firms’ age and size) should be taken into account during the implementation of a business strategy.     

The sustainability of fiscal policies in the European Union

This paper examines the stationarity of the inclusive-of-interest public deficit for five European Union economies, four of them being recently selected for entry into the European Monetary Union. Unit root tests are used not only to examine structural breaks and cointegration analysis, but also to investigate for regime shifts. They support the occurrence of sustainable deficits for the Greek, Spanish, and Portuguese economies. On the contrary, Italy and Belgium may incur unsustainable deficits, implying that their selection in Phase 2 of the European Monetary Union is questionable. This paper was presented at the Forty-Fifth International Atlantic Economic Conference, Rome, Italy, March 14–21, 1998.     

Harmful diversification: Evidence from alternative investments

Alternative assets have become as important as equities and fixed income in the portfolios of major investors, and so their diversification properties are also important. However, adding five alternative assets (real estate, commodities, hedge funds, emerging markets and private equity) to equity and bond portfolios is shown to be harmful for US investors. We use 19 portfolio models, in conjunction with dummy variable regression, to demonstrate this harm over the 1997–2015 period. This finding is robust to different estimation periods, risk aversion levels, and the use of two regimes. Harmful diversification into alternatives is not primarily due to transactions costs or non-normality, but to estimation risk. This is larger for alternative assets, particularly during the credit crisis which accounts for the harmful diversification of real estate, private equity and emerging markets. Diversification into commodities, and to a lesser extent hedge funds, remains harmful even when the credit crisis is excluded.     

Identification of Greek Takeover Targets and Coherent Policy Implications

The main purpose of this paper is the identification of the characteristics of takeover targets in a small open economy like Greece, using the market for corporate control (MCC) hypothesis as theoretical background. Contrary to this hypothesis, the results indicate that the motives for merging or acquisition activities are basically of strategic character. Using a sample of 35 acquired and 105 non‐acquired firms, the sampling process was initially performed by a modified methodology of state‐based sampling, even if its nature cannot be recognized by the classical maximum likelihood estimator (MLE) of logit model. Subsequently, taking into account the small size of the sample, we develop and use, in the logit context, the bootstrap MLE as an advanced alternative method for reducing inherit bias and inefficiency. The findings remain uniform supporting the strategic motives explanation in actual takeover activities, a fact that clearly illustrates the framework of merger policies followed by the Greek Competition Committee during the period under study.     

Impact of futures on comovements for UK cross-listed equities

This paper uses La Porta et al.'s [La Porta, R., De Silanes, F.L., Shleifer, A., Vishny, R.W., 1998. Law and finance. Journal of Political Economy 106 (6), 1113–1155] capital markets regulatory classification to analyse the impact of information contained in various futures contracts on the magnitude and persistence of volatility spillovers between markets. The focus here is to examine the impact of futures contracts on comovement between markets. We examine the behavior of foreign cross-listed shares that have listed in different regulatory environments. In particular, the paper analyses spillover effects between foreign cross-listings in tougher, similar and more lax regulatory environments with respect to the relevant domestic indices (FTSE100) and also with the home portfolios of cross-listed equities in the UK. We find that futures variables have a significant impact on the magnitude and persistence of volatility spillovers between markets.     

A case study investigating the impact of the London 2012 Olympic and Paralympic Games on participation in two non-traditional English sports,Judo and Fencing

The hosting of the London 2012 Olympic and Paralympic Games (LOPG) brought with it detailed legacy plans aiming to ‘Inspire a Generation’. The idea that hosting a sports mega-event will encourage the host population to engage in more physical activity is commonly used by governments to justify the large investments they make. The aim of this research paper was to investigate the impact that hosting the 2012 Games had on grass-root sports participation within the host nation. This paper focuses on two non-traditional English sports, Fencing and Judo and investigated the changes in mass sports participation. The membership rate analysis of our sample highlighted an overall increase in participation between 2007 and 2013, in both Judo and Fencing. The data gathered from the interviews with the head office staff at the National Governing Bodies (NGBs) and local club coaches suggested that the grass-root participation programmes were the most effective way of increasing participation, rather than the reliance, solely on the inspiration effect from hosting the LOPG itself. The study highlighted the importance of strengthening communication between local voluntary clubs and the NGB, to ensure sports could promote themselves and capitalise on this global sporting phenomenon, which provided unprecedented media coverage and opportunities for these non-traditional sports. This case study provides initial results relating to the effect that a major international multi-sport event can have in the development of non-traditional sports in the host population, in terms of membership variations, participation programmes and organisational dynamics.
