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...

The purpose of this study was to investigate and analyze the relationship between foreign exchange and capital market dynamics in Nigeria from January 1999 to February 2018. The study deployed the Non-Linear-ARDL model to study the dynamics of exchange rate and the capital market in Nigeria. The...

Using positive semidefinite supOU (superposition of Ornstein-Uhlenbeck type) processes to describe the volatility, we introduce a multivariate stochastic volatility model for financial data which is capable of modelling long range dependence effects. The finiteness of moments and the second...

Describes the behavior of financial markets as functions of the variables 'price return' and 'time' based on the net difference between ask and bid volumes over a unit period, thereby suggesting that at least a negative non-trivial price return extreme exists for a unit period. This admittedly...

In this paper we present simulations of economic performance of the Polish economy based on a quarterly econometric model. The model consists of 22 stochastic equations, which link the financial market with the real economy. The purpose of the research is to present effects of changes to...

This paper aims to study the determinants of financial deepening (FD) in Mexico. FD is measured as the fraction of total credit assigned to private sector as a proportion of GDP. The explanatory variables include: enforcing contracts (rule of law) and institutions; bank regulation; bank...

This paper discusses how central banking is evolving in light of recent experience, with particular emphasis on the incorporation of uncertainty into policy decision-making. The sort of post-crisis uncertainty that central banks are dealing with today is more profound than that which is...

In this paper we analyze a multivariate non-stationary regression model empirically. With the knowledge about unconditional heteroscedasticty of financial returns, based on univariate studies and a congruent paradigm in Gürtler and Rauh (2009), we test for a time-varying covariance structure...

The study aims to examine reasons for agribusiness proprietors seeking unconventional loans, where conventional lenders offer loans at lower interest rates. Using cross-sectional data analysis, the study revealed the type of clients served by unconventional lending sector: Households that are...

We examine the effectiveness of GARCH models and the SV model in foreign exchange rates and the stock indices of the BRICS. The empirical analysis is conducted using the daily log returns. The data cover the period 13/05/1999-22/11/2018. The theoretical results are confirmed by running the...
