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.     

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.     

An investor sentiment barometer — Greek Implied Volatility Index (GRIV)

In this paper, we propose a new measure of Greek equity market volatility based on the prices of FTSE/ATHEX-20 index options. Greek Implied Volatility Index is calculated using the model-free methodology that involves option prices summations and is independent from the Black and Scholes pricing formula. The specific method is applied for the first time in a peripheral and illiquid market as the Athens Exchange.The empirical findings of this paper show that the proposed volatility index includes information about future realized volatility beyond that contained in past volatility. In addition, our analysis indicates that there is a statistically significant negative and asymmetric contemporaneous relationship between the returns of the implied volatility index and the underlying equity index. Finally, the volatility transmission effects on the Greek stock exchange from two leading markets, namely the New York Stock Exchange and the Deutsche Börse, are tested and documented.     

Green Consumption Behavior Antecedents: Environmental Concern,Knowledge, and Beliefs

The present study adds to the evolving literature on green consumer behavior by examining through statistically robust methods the effect and interrelationships of the key constructs of environmental concern, consumer environmental knowledge, beliefs about biofuels, and behavioral intention (i.e., willingness to use and pay) in the context of biofuels. Data were collected through a survey of 1695 respondents. Hypotheses are based on a literature review and a pilot study, and the conceptual structural model developed is tested through structural equation modeling. Results show that concern for the environment has a positive and direct impact on environmental knowledge, beliefs, and behavioral intention. Also, demographics determine levels of concern for the environment and environmental knowledge. All constructs associate positively with one another delineating that the interdependencies between them are important when accounting for environmental behavior. Future research should validate present results with the use of cross‐cultural samples and investigate whether environmental concern increases due to social desirability response bias.     

Real effective exchange rate and the constant elasticity of substitution assumption

The real effective exchange rate (REER) is an aggregation of several bilateral real exchange rates assuming constant elasticity of substitution (CES) between goods from different countries. We investigate the validity of the CES assumption by estimating manufacturing export equations for 56 countries over 26 years. Under the CES assumption, splitting the REER into two components should not increase the fit in an export equation and the coefficients on the two REERs should be equal. We reject both these implications and find that the export equations with two REERs—vs. OECD and vs. nonOECD countries—perform better than the traditional ones.     

Volatility and error transmission spillover effects: Evidence from three European financial regions

This study uses the multivariate GARCH-BEKK modelling approach to examine the transmission of news (both volatility and error) between portfolios of cross-listed equities within three European financial regions, that is, the Scandinavian (Denmark, Sweden, Finland and Norway), the Germanic (Austria, Switzerland and Germany) and the French area (Brussels, France, Italy, Holland and Spain). We find that the Finnish and Danish portfolios of cross-listed equities are the main transmitters of volatility relative to the Swedish and Norwegian portfolios of cross-listed equities. On the other hand, the Swiss portfolio of cross-listed equities is the major exporter of volatility and error to the other portfolios of cross-listed equities in the Germanic stock market area. Finally, the Paris, Amsterdam and Brussels stock exchanges are the major exporters of volatility and error to the portfolios of cross-listed equities traded on the Milan and Madrid stock exchanges.     

Asset price volatility and government revenue

This paper investigates the effect of commercial, residential property and equity price volatility on the variability of cyclically adjusted government revenue. We find significant evidence that asset price volatility increases the variability of government revenue. A 1% increase in equity price volatility increases government revenue variability by 0.37–0.44%. An increase in residential property price volatility increases revenue volatility by about 0.15–0.22%, whereas this effect diminishes to 0.11% in case of commercial property price. This evidence reflects the automatic increase of government revenue variability due to asset price movements and supports arguments in favour of adjusting fiscal variables for both business cycle and asset price changes. However, we also find evidence that equity price variability increases revenue variability even when government revenue is adjusted for both economic and asset price cycles, indicating the presence of more complicated dynamics between fiscal variables and asset price changes.
