We re-examine the efficiency of real estate markets based on the Escanciano-Lobato (2009) autocorrelation test which we improved by means of wild bootstrapping. Through Monte Carlo simulation, we find that the wild bootstrap-based autocorrelation test has very good performance even in small...

We suggest that there is a significant relationship between cross-market comovement and time varying volatility. The time-varying component of cross-market dependence is attributed to the intertemporal risk-return adjustment by rational, risk-averse investors who systematically revise their...

This paper proposes the Shannon entropy as an appropriate one-dimensional measure of behavioural trading patterns in financial markets. The concept is applied to the illustrative example of algorithmic vs. non-algorithmic trading and empirical data from Deutsche Börse's electronic cash equity...

We assess the IMF supported program on the structural reforms after the Asian crisis in 1997 in terms of the before-after, with-without and event study approaches with applying a time varying parameter model to the nine Asian stock markets. All the supported countries except for Thailand (...

We use a unique dataset of bond downgrades from a niche rating company that has been found to be reacting faster to publicly available information than its competitors. Using regime-switching models we propose risk measures to quantify stock return disturbances (distress costs) associated with...

This paper considers the role of valuation in portfolio theory. In particular, we examine value-price ratios and their dynamic properties. Five valuation principles are proposed, namely the separability of prices and valuations, the asymptotic convergence of value-price ratios, the finite...

Statistical properties of an order book and the effect they have on price dynamics were studied using the high-frequency NASDAQ Level II data. It was observed that the size distribution of marketable orders (transaction sizes) has power law tails with an exponent 1+mu_market=2.4 plus-minus 0.1....

A number of inefficiencies in the art market stress the fact that art remains a highly risky investment. The art market is characterized by high illiquidity, inefficient market information, high transaction costs, long transaction time and the absence of a hedging mechanism. Therefore, unlike...

The Chicago Board Options Exchange (CBOE) Volatility Index, VIX, is calculated based on prices of out-of-the-money put and call options on the Samp;P 500 index (SPX). Sometimes called the investor fear gauge, the VIX is a measure of the implied volatility of the SPX, and is observed to be...

This paper studies the normality of two portuguese stock exchange indexes, using daily returns for the period 1990-1995. The results of the tests allow to discard the hypothesis of normality. Weak form efficiency, evaluated through runs tests, is also rejected, while daily returns turn out to be...
