Instabilities in the price dynamics of a large number of financial assets are a clear sign of systemic events. By investigating a set of 20 high cap stocks traded at the Italian Stock Exchange, we find that there is a large number of high frequency cojumps. We show that the dynamics of these...

This paper an attempt to examine the movement and linkages (relationship) between Gold price and CNX Nifty index during the period from 2000 to 2018. By testing the normality, stationary, movements and linkages of sample variables through the econometric tools like descriptive statistics, ADF,...

In this paper we have assessed an influence of the NYSE Stock Exchange indexes (DJIA and NASDAQ) and European Stock indexes (DAX and FTSE) on the Warsaw Stock Exchange index WIG within a framework of a GARCH model. By applying a procedure of checking predictive quality of econometric models as...

We develop a discrete-time affine stochastic volatility model with time-varying conditional skewness (SVS). Importantly, we disentangle the dynamics of conditional volatility and conditional skewness in a coherent way. Our approach allows current asset returns to be asymmetric conditional on...

We investigate predictive abilities of nonlinear models for stock returns when density forecasts are evaluated and compared instead of the conditional mean point forecasts. The aim of this paper is to show whether the in-sample evidence of strong nonlinearity in mean may be exploited for...

Exchanged Traded Funds (ETFs) have become one of the largest investment opportunities today. They present special features that differentiate them from other investment funds, in which the most important are their traded shares. Their share prices are market oriented and are not necessarily...

Market risk measurement has a long tradition in finance and it has been drawing the attention of many academic studies since Markowitz (1952). But the CAPM model (and derived models) assumptions have been targets of much criticism, in the sense that beta estimation may be imprecise. The...

For six important energy futures markets, this study examines whether large price movements (i.e., jumps) are related to the arrival and information content of scheduled macroeconomic announcements. Since prior studies by Kilian and Vega [(2011) Review of Economics and Statistics, 93, 660–671]...

This paper explains why a two-component GARCH model as proposed by Ding and Granger (1996) or Engle and Lee (1999) can be an ideal alternative model for practitioners in modeling stock return volatility. I show that the two-component GARCH model can easily capture the slow hyperbolic decay of...

This paper studies nonparametric identification and counter- factual bounds for heterogeneous firms that can be ranked in terms of productivity. Our approach works when quantities and prices are latent rendering standard approaches inapplicable. Instead, we require observation of profits or...
