in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...

  The main purpose of present study is to analyze the relationship between stock and exchange markets in two Asian countries, Iran and South Korea. A monthly time series of stock price and exchange rate are used over the period 2002: 05 - 2012: 03. The data is collected from the Central Bank of each country and WDI. The calculated stock return and real exchange rate change are used in analysis....

Considering the growing importance of sustainable investments worldwide, we explore volatility transmission effects between EURO STOXX Sustainability Index and stock market indexes its stocks. Using daily index return data, during 2000–2022, covering COVID-19 pandemic, Multivariate Generalized Auto-Regressive Conditional Heteroskedasticity (MGARCH) models are used to if indices felt pandemic im...

Crude oil and natural gas are crucial to the Russian economy. Therefore, this study examined interconnections between crude price, economic policy uncertainty (EPU) over period 1994–2019 using multivariate DCC-MGARCH models. The findings show that there strong (co-movement) energy prices EPU in Russia, it might be misleading assume independence or neutrality variables. Although Russia is also a...

This paper proposes structured parametrizations for multivariate volatility models, which use spatial weight matrices induced by economic proximity. These structured speci…cations aim at solving the curse of dimensionality problem, which limits feasibility of model-estimation to small cross-sections for unstructured models. Structured parametrizations possess the following four desirable proper...
