The paper considers the problem as to whether financial returns have a common volatility process in the framework of stochastic volatility models that were suggested by Harvey et al. (1994). We propose a stochastic volatility version of the ARCH test proposed by Engle and Susmel (1993), who...

Oil is perceived as a good diversification tool for stock markets. To fully understand this potential, we propose a new empirical methodology that combines generalized autoregressive score copula functions with high frequency data and allows us to capture and forecast the conditional...

This study aims to verify whether there are any macroeconomic variables that have significant power in predicting the dynamics of financial markets. In particular, we want to identify an econometric model that can guide the strategies of operators in building their investment portfolios. The...

The asymmetry in price pressure from seller vs. buyer-initiated transactions is identified as valuable measure of downside liquidity for corporate bonds. While the evidence of illiquidity on risk premium in the cross-section of corporate bonds is mixed, the aggregate liquidity asymmetry has a...

This paper investigates the existence of long-run benefits of the international diversification in the equity markets of the US and the Pan-European Stock Exchange. The study which spans 6 years uses weekly data based on closing values of the general indices of Dow & Jones Industrial Average and...

We document a novel channel through which coordinated trading exerts externalities on financial markets. We study the impact of a financial advisory firm that recommends frequent reallocations between equity and bond funds to Chilean pension investors. The recommendations generate large and...

This study assesses the effect of fund-level and systemic factors on the performance of mutual funds in the context of changing market conditions. A Markov regime-switching model is used to analyze the performance of 33 South African equity mutual funds from 2006 to 2019. From the results, fund...

The asset allocation decision often relies upon correlation estimates arising from short-run data. Short-run correlation estimates may, however, be distorted by frictions. In this paper, we introduce a long-run wavelet-based correlation estimator, distinguishing between long-run common behavior...

High frequency data typically exhibit asynchronous trading and microstructure noise, which can bias the covariances estimated by standard estimators. While a number of specialised estimators have been developed, they have had limited availability in open source software. HighFrequencyCovariance...

Do women invest differently than men? We contribute to the answer of this question by analysing the Panel on Household Finances (PHF) of the German Bundesbank. This representative panel collects a wide variety of behavioural and financial variables in the area of household finance. We find that...
