this paper focuses on the residential sector demand for electricity, natural gas and petroleum products (kerosene, gas oil and lpg) in iran in the context of a popular locally flexible functional forms - “the almost ideal demand system (aids)”. we pay explicit attention to the theoretical regularity conditions of positivity, monotonicity, and curvature. we treat the curvature property as a main...

BACKGROUND Ozone is a three-oxygen molecule (O3). Ozone therapy (OT) is systematically effective when pathological inflammatory and immunologic processes are activated. Among of these conditions are wound healing, macular degeneration related to aging, and conditions that are ischemic or infectious. AIMS The aim of this study was to determine the effects of OT on wound healing of intestinal a...

In this paper we intend to examine the application of Kullback-Leibler, Hellinger and LINEX loss function in Dynamic Linear Model using the real price of oil for 106 years of data from 1913 to 2018 concerning the asymmetric problem in filtering and forecasting. We use DLM form of the basic Hoteling Model under Quadratic loss function, Kullback-Leibler, Hellinger and LINEX trying to address the ...

many reports that appeared during the last 20 years have shown that atmospheric pollution causes serious damage to human health and to environment. electricity generation from fuel fossil is one of the major sources of pollution and considerable share of this damage. the price of electricity in iran, as in many other countries also, includes only the production of private costs and ignores any ...

We introduce a novel approach to estimating latent oil risk factors and establish their significance in pricing non-oil securities. Our model, which features four factors with simple economic interpretations, is estimated using both derivative prices and oil-related equity returns. The fit is excellent in and out of sample. The extracted oil factors carry significant risk premia, and are signif...
