VOLATILITY MODELING IN PERIODS OF CRISIS: ANALYSES OF ALTERNATIVE DISTRIBUTIONS IN BRIC AND THE US
Keywords: Effects of financial crisis of 2008, Time Series, Different Distributions
AbstractThe real estate market crisis in North America in 2007 has strongly affected the capital markets in the US and Europe. Financial crises of the magnitude of that of 2007/2008 bring up important issues about financial markets. This paper investigates how distribution specification influences volatility modeling in the period including the financial crisis of 2007/2008. Analysis was carried out by using weekly index data from the main stock exchanges of BRIC (Brazil, Russia, India and China) and the United States, using the APARCH model. The modeling is done in three subdivisions of the sample considering six different distributions, normal, skewed normal, t-student, skewed t-student, generalized and skewed generalized. Results of this research showed a variation in the distribution better adjusted during the crisis period, for almost all countries. Variation in the distributions as well as in the significances and magnitudes of the coefficients can lead to the conclusion that periods of financial oscillation and instability can influence the modeling of financial series, changing the magnitude and significance of coefficients, and be due to the contagion effect.
