Is Rationing an Option for Approaching Healthcare Services Provision? The Case of the Greek Cardiac Patients

This paper attempts to address some of the issues surrounding rationing of healthcare services, with application to Greece’s delivery of cardiac services. To this end, first, we provide highlights of the current debate concerning rationing worldwide and critically discuss them. Following that, an empirical analysis of the way ‘key’ stakeholders perceive rationing issues in Greece, is performed. Findings indicate that rationing is a highly disputed approach, subject to individualistic interpretations and moral issues. At policy level, it becomes evident that rationing is a mixture rather than a single policy concern, depending on a complicated range of locally-based reconciliation made at various levels of interested parties. Hence, no universal formula exists to fit all countries’ healthcare systems and further case-by-case research, is required.     

Stock market reaction to dividend announcements: Evidence from the Greek stock market

This study investigates the market reaction to cash dividend announcements for the period 2000–2004 employing data from the Athens Stock Exchange (ASE). In particular, the paper examines both the stock price and trading volume response to dividend distribution announcements. Dividend distributions in Greece demonstrate noticeable differences to those of the US, the UK and other developed markets. First, dividends in Greece are paid annually rather than quarterly or semi-annually. Second, the Greek corporate laws 2190/1920 and 148/1967 specifically designate the minimum amount for distribution from the taxed corporate profits. Third, neither tax on dividends nor on capital gains was imposed during the period under examination. Fourth, Greek listed firms are characterized by high ownership concentration where major owners are usually involved in management and therefore have less need for dividend announcements as an information source. Despite this neutralized information and tax environment, we document significant market reaction to dividend change announcements, lending support to the “information content of dividends hypothesis”.     

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.     

Investigating the valuation effects of reverse takeovers: evidence from Europe

This study examines a European sample of 222 private firms that opted for going public through a reverse takeover transaction during the period 1992–2011. In particular, our study investigates whether reverse takeovers announcements are value-increasing transactions, especially in countries that follow strong governance structures. Moreover, the post-reverse takeover stock price and operating performance is also at the epicenter of the current study. Employing the classical event study methodology, we document significant wealth gains for the shareholders of public firms involved in reverse takeovers. The market reaction is stronger when stricter corporate governance structures prevail in the countries where public firms trade. However, the short-term gains seem to revert to substantial losses over the long-term lending support to the overreaction phenomenon. We further detect negligible improvement in the post-reverse takeover financial performance of the new entity raising further concerns over the efficacy of such transactions.     

Semi-non-parametric estimates of substitution for Canadian monetary assets

We estimate the dynamic Fourier expenditure system to obtain consistent estimates of short-run and long-run Morishima elasticities of substitution for Canadian liquid assets. We argue that the variability of the estimated elasticities and evidence of less than perfect substitution between monetary assets interferes with the successful use of simple-sum aggregates and traditional log-linear money-demand functions.
Calibrations semi-non-paramétriques de la substitution pour des actifs monétaires canadiens . Les auteurs calibrent le système dynamique de dépenses à la Fourier pour obtenir des estimations cohérentes des élasticités de substitution à la Morishima à court et à long termes pour des actifs monétaires canadiens. Ils suggèrent que la variabilité des élasticités estimées et la constatation que la substitution n'est pas parfaite entre les actifs monétaires rendent difficile un usage heureux des agrégats de simple somme et des fonctions log-linéaires de demande de monnaie.
