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

Volatility clustering and asymmetry are considered as an essential element in time series data analysis for portfolio managers. This study is conducted to analyze the volatility clustering and asymmetry occurrence by employing different GARCH models. Data is collected from 11 Religion Dominant...

This Article attempts to define hedge funds and to distinguish them from a variety of similar investment funds. After reviewing the hedge fund definition in the U.S. and the EU, this Article argues that the current regulatory framework, which defines hedge funds by reference to what they are not...

In this paper, I develop a model of oligopoly with shareholder voting. Instead of assuming that firms maximize profits, the objective of the firms is decided by majority voting. This implies that portfolio diversification generates tacit collusion. In the limit, when all shareholders are...

In this paper I test for and model volatility jumps for the General Index (GD) of the Athens Stock Exchange (ASE), expanding the previous literature on the ASE in various ways. Using intraday data I first construct various state-of-the-art realized volatility estimators which I then use in...

We consider a mean-variance general equilibrium economy where the expected returns for controlling and non-controlling shareholders are different because the former are able to divert a fraction of the profits. We find that when investor protection is poor, asset return correlation affects...

The IPO filing volume is positively related to changes in market volatility, especially when market returns are at ‘normal' levels. This is consistent with the view that filing with the SEC gives would-be issuers an ‘option' on market valuations. Creating this option is attractive not only...

We estimate a Pareto distribution for loan losses, as an alternative to the commonly used Vasicek distribution, using simulated data. A key assumption in the construction of Vasicek distribution is that firm-level risk is idiosyncratic. It also assumes that firm exposure to systemic risk is...

The London Interbank Offered Rate (Libor) is a set of vital benchmark interest rates to which hundreds of trillions of dollars of financial contracts are tied. The rates are set each day via a survey of large banks. In recent years, strange behavior of the rates have caused observers to question...
