Analysis of Models (NAGARCH & APGARCH) by Using Simulations

open access: diamondJournal of Economics and Administrative Sciences, 2022
Simulation experiments are a means of solving in many fields, and it is the process of designing a model of the real system in order to follow it and identify its behavior through certain models and formulas written according to a repeating software style with a number of iterations.

An APGARCH Investigation of the Main Influences on the Gold Price

open access: greenSSRN Electronic Journal, 2005
The paper investigates whether the asymmetric power GARCH model (APGARCH) introduced by Ding, Granger and Engle (1993) captures the dynamics of the gold market. This paper examines both the cash and futures price of gold and significant economic variables identified during two periods: the 1987 crisis and the 2001 crisis.

The impact of ESG news on the volatility of the Portuguese stock market—Does it change during recessions? [PDF]

open access: yesBusiness Strategy and the Environment, Volume 32, Issue 8, Page 5821-5832, December 2023., 2023
Abstract This paper assesses how environmental, social, and governance (ESG) news influence Portuguese stock market volatility depending on the business cycle. Given the lack of an adequate index to capture the effects of ESG media on the Portuguese stock market, a News Sentiment Index is developed.
