This paper extends the intertemporal capital asset pricing model (ICAPM) to integrate the heterogeneous trading behavior of three groups of investors; rational utility maximizers, positive feedback, or momentum, traders, and fundamental traders. Using several contemporary fundamental factors to proxy for the latter of these investors’ trading patterns, the interaction of these three groups of investors is explored in the G-7 markets using monthly stock market prices. There is no evidence that positive feedback traders are present in the sample data. Fundamental traders are however observable. This finding suggests that although positive feedback traders may drive stock prices in the short-run, as is typically observed in higher frequency data, fundamental traders likely play a role in pushing prices back to their fundamental value in the longer-run. 相似文献

The intraday nonparametric estimation of the variance–covariance matrix adds to the literature in portfolio analysis of the Greek equity market. This paper examines the economic value of various realized volatility and covariance estimators under the strategy of volatility timing. I use three types of portfolios: Global Minimum Variance, Capital Market Line and Capital Market Line with only positive weights. The estimators of volatilities and covariances use 5-min high-frequency intraday data. The dataset concerns the FTSE/ATHEX Large Cap index, FTSE/ATHEX Mid Cap index, and the FTSE/ATHEX Small Cap index of the Greek equity market (Athens Stock Exchange). As far as I know, this is the first work of its kind for the Greek equity market. Results concern not only the comparison of various estimators but also the comparison of different types of portfolios, in the strategy of volatility timing. The economic value of the contemporary non-parametric realized volatility estimators is more significant than this when the covariance is estimated by the daily squared returns. Moreover, the economic value (in b.p.s) of each estimator changes with the volatility timing. 相似文献

The main objective of this paper is to investigate whether differences in institutional characteristics result in different capital structure determination among countries. First, we analyze the institutional setting in Greece compared with that of other countries. Second, we provide survey information about the determinants of capital structure in Greece and compare our findings with those of similar surveys in the United States and Europe based on Graham and Harvey [Graham, J., & Harvey, C. (2001). The theory and practice of corporate finance: Evidence from the field. Journal of Financial Economics, 60, 187–243], Bancel and Mittoo [Bancel, F., & Mittoo, U. (2004). Cross-country determinants of capital structure choice: A survey of European firms. Financial Management, 33(4), 103–133 Winter 2004] and Brounen, de Jong and Koedijk [Brounen, D., de Jong A., & Koedijk, K. (2006). Capital structure policies in Europe: Survey evidence. Journal of Banking and Finance, 30, 1409–1442] respectively. Greek firms seem to follow an own-business policy and seem to care more about the disadvantages of debt than try to exploit its advantages. Financial distress considerations, market timing and competitiveness are important factors, whereas agency costs of equity, pecking order and the signalling theory do not seem to apply. Conclusions are relatively similar with those of other countries, though specific differences that can be attributed to the different institutional settings do exist. In general however, we conclude that differences in institutional characteristics do not seem to affect the way of thinking of financial managers when they decide on capital structure issues. 相似文献

Despite its contribution to the national economy, domestic tourism is one of the most neglected and under-researched forms of tourism in the literature. This study tested an integrated path model examining the interrelationships between destination image, perceived quality, satisfaction and behavioural intentions, using domestic tourists who visited Eilat, Israel. The findings support the hierarchical relationships between image, quality, satisfaction and behavioural intentions. In addition, the affective image component was found to exert a far greater impact on the overall destination image than the cognitive component. The study establishes a better understanding of domestic tourists’ destination image and behavioural intention formulation. It also provides a number of implications for destination managers targeting the voluminous domestic segment. 相似文献

This paper assesses the limitations that the Stability and Growth Pact has imposed on Italy’s economic recovery and its debt reduction. By evaluating Germany’s fiscal policy since 1997, the paper offers recommendations for the Italian authorities. Measures put forward by European Union institutions are hampering Italy’s economic recovery, and evidence indicates that fiscal consolidation is ineffective in reducing the debt-to-GDP ratio. A balanced budget fiscal injection seems the only way for Italy to escape from its economic slump without further violations of the SGP. The paper concludes that the Pact either needs to be reformed or replaced by a central fiscal authority. 相似文献

Objectives To evaluate a multivenue educational campaign aimed at increasing the use of car restraints in Greater Athens, Greece. Methods From October 1997 to June 1998, the campaign was implemented by a road safety coalition comprising 50 governmental and non-governmental organizations, while during the same period, seat belt law enforcement was not intensified. A pre-intervention survey was conducted in the summer of 1996 among the occupants of 1400 passenger cars and a post-intervention survey was carried out in the summer of 1998 (2250 cars). Both surveys followed the same protocol, focusing on the availability and use of seat belts. The data from the two surveys were modeled through multiple logistic regression. Results The odds ratio of seat belt use was significantly higher in 1998 than in 1996 (1.8 with 95% confidence interval = 1.5-2.1). Improvement was evident in highway traffic and among 25-64 year-old car occupants, but it was minimal among rear seat passengers, younger occupants, and in low-speed city and suburban traffic. There is evidence from the 1998 surveys that among front seat occupants, those travelling in larger engine capacity cars, frequently equipped with airbags, were less likely to use seat belts, whereas seat belting was more frequent among occupants of newer car models. Conclusion An education and information campaign in a Southern European country resulted in increased prevalence of seat belt use. A more intensive and sustained effort is required, however, to increase seat belt use in low-speed traffic and among rear seat occupants. 相似文献

A brand is a mean of product differentiation and a kind of a sign by which we can distinguish one commodity from another. Consumers' utility, as well as commodity prices are affected by brands. Therefore, the market positioning of branded products is important for firms, too, since it affects profits. This paper presents a theoretical framework that incorporates aspects of brand in microeconomic analysis and the tools for an effective market positioning of differentiated products. A case study illustrates the workings of the methodology; the application evaluates the quality of major tyres producers and undertakes their market positioning. 相似文献

The purpose of the paper is to examine the nature of Greek regional unemployment. The paper contributes to the literature assessing the stochastic properties of Greek unemployment rate in the context of the Greek regions by relying on various univariate and panel unit root tests. In particular, recently developed and more powerful panel unit-root tests that control for structural breaks, heterogeneity and cross-sectional dependence in the panel are employed. The results show that in all cases, after taking into account the fact that regional unemployment rates in Greece are subject to a structural break, the null hypothesis of a unit root is not rejected, indicating that the Greek regional unemployment series are non-stationary with the presence of a structural break. 相似文献
