This paper applies ARDL and Nonlinear ARDL models to long-term inflation targeting policy mechanisms in the United States and China to assess the impact of oil price dynamics and asymmetries on inflation expectations in the two countries, as well as the difference of this impact before and after...

If high-frequency stock returns display a leverage effect, then lower-frequency stock returns will generally display negative skewness. In addition, the conditional skewness of lower-frequency returns will depend on their conditional correlation with volatility shocks for the same time horizon....

This paper introduces a unified multivariate overnight GARCH-Ito model for volatility matrix estimation and prediction both in the low- and high-dimensional set-up. To account for whole-day market dynamics in the financial market, the proposed model has two different instantaneous volatility...

A plethora of academic papers on generalized autoregressive conditional heteroscedasticity (GARCH) models for bitcoin and other cryptocurrencies have been published in academic journals. Yet few, if indeed any, of these are employed by practitioners. Previous academic studies produce results...

The paper provides an introductory guide for active managers that illustrates econometric techniques for alpha generation in active asset management. For modelling stock market returns three different model types are discussed: (i) fair value models that identify over- and undervaluations, (ii)...

SVR-GARCH model tends to "backward eavesdrop" when forecasting the financial time series volatility in which case it tends to simply produce the prediction by deviating the previous volatility. Though the SVR-GARCH model has achieved good performance in terms of various performance measurements,...

Using a flexible statistical framework that accounts for time-varying skewness and leptokurtosis, we examine the stochastic behavior of Bitcoin in comparison to five major currencies. The empirical findings reveal that the distribution of all series is leptokurtic. Once the effect of...

We introduce a new class of semiparametric dynamic autoregressive models for the Amihud illiquidity measure, which captures both the long-run trend in the illiquidity series with a nonparametric component and the short-run dynamics with an autoregressive component. We develop a GMM estimator...

This paper aims to empirically investigate the dynamic connectedness between oil prices and stock returns of clean energy-related and technology companies in China and U.S. financial markets. We apply three multivariate GARCH model specifications (CCC, DCC and ADCC) to investigate the return and...
