Arbitrage is non-parametrically examined and empirically analyzed in US equity markets. Firstly, analyzed are the properties of arbitrage; and secondly, the factors explaining arbitrage are tested. Empirical analysis concerns a decade of intraday data of five US equity indices and is also...

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...

We test for and model the volatility jumps for three major indices of the Athens Stock Exchange (ASE). Using intra-day data we first construct several, state-of-the-art realized volatility estimators. We use these estimators to construct the jump components of volatility and perform various...

In this paper I examine the properties of four realized correlation estimators and model their jumps. The correlations are between the French, German and Greek equity markets. Using intraday data I first construct four state-of-the-art realized correlation estimators which I then use to testing...

Using high-frequency intraday data, we construct, test and model seven new realized volatility estimators for six international equity indices. We detect jumps in these estimators, construct the jump components of volatility and perform various tests on their properties. Then we use the class of...

Range-based volatility estimators are analyzed in both daily and intraday sampling frequency and are also compared to the realized volatility estimator. The family of realized range-based estimators is extended as three range-based estimators are introduced. These three realized Parkinson...

This study tests the 'Market for Corporate Control' hypothesis in a small open economy. The results appear to favour rejection of this hypothesis indicating that acquisitions have not been driven by managerial-disciplinary motives. Moreover, it is found that a logit model outperforms other...

The purpose of the present study is to identify the factors affecting the non-performing loans rate (NPL) of Eurozone’s banking systems for the period 2000-2008, just before the beginning of the recession. In our days, Eurozone is in the middle of an unprecedented financial crisis,...

The Halloween effect refers to a calendar anomaly that can be easily exploited and calls for buying the market index in the end of October each year and switching to treasury bills at the end of April the following year. The effect has only been studied on a 'calendar-month' basis and primarily...

The estimation of the parameters of logit model is mostly performed with method of maximum likelihood. However, the classical maximum likelihood estimators are biased and inefficient in appearance of small samples. The jackknife maximum likelihood estimator improves the above problems but still...
