This paper introduces the idea that the variances or correlations in financial returns may all change conditionally and slowly over time. A multi-step local dynamic conditional correlation model is proposed for simultaneously modelling these components. In particular, the local and conditional...

This study examines the volatility and correlation and their relationships among the euro/US dollar exchange rates, the S&P500 equity indices, and the prices of WTI crude oil and the precious metals (gold, silver, and platinum) over the period 2005 to 2012. Our model links the univariate...

We propose a new model for the variance between multiple time series, the Regime Switching Dynamic Correlation. We decompose the covariances into correlations and standard deviations and the correlation matrix follow a regime switching model; it is constant within a regime but different across...

This paper proposes a consistent estimator for the realized covariance of high frequency and asynchronous assets' returns that are contaminated by microstructure noise. The main contribution is the introduction of the pseudoaggregation which transforms the observations into series with the same...

In this paper we analyze and interpret the quote price dynamics of 100 NYSE stocks stratified by trade frequency. We specify an error-correction model for the log difference of the bid and the ask price with the spread acting as the error-correction term, and include as regressors the...

This study analyzes the effectiveness of bank risk management in ASEAN countries and examines the specific role of risk governance in enhancing a bank's risk management effectiveness. Our results show that the risk management effectiveness of banks in ASEAN countries is low. Furthermore, by...

The main thesis in this manuscript is that a social choice theory based on aggregating individual preferences and values is insufficient to confront the social choices that today’s world is facing. It is defended in here that institutions play a critical role in any social choice, and that the...

This study examines the influence of capital adequacy ratio and bank size on the profitability of Ghanaian banks from 2008 to 2017, while also considering macroeconomic factors such as inflation and the monetary policy rate. Using return on assets (ROA) as the measure of profitability and...

This study aims to compare the financial performance of several green stock market indices with their conventional counterparts. Several time periods are analyzed, and several financial indicators are considered. It appears that the StoxxGlobal ESG Environnemental Leader outperforms its...
