این مقاله تقاضای برق، گازطبیعی و سایر فرآورده ها (نفت سفید، نفت گاز و گازمایع) در بخش خانگی ایران را با استفاده از فرم تابعی «سیستم تقاضای تقریباً ایده آل (aids)» مورد بررسی و تجزیه و تحلیل قرار می دهد. نظام مندی نئوکلاسیکی شامل «مثبت بودن»، «یکنواختی» و «انحناء» با استفاده از محدودیت های نظری که توابع تقاضای انعطاف پذیر می بایست از آن ها تبعیت نمایند، اعمال شده است. در این مطالعه محدودیت «انحنا...

While there is good reason to expect crude oil production to be non-linear, previous studies that have examined the stochastic properties of crude oil production have assumed that crude oil production follows a linear process. If crude oil production is a non-linear process, conventional unit root tests, which assume linear and systematic adjustment, could interpret departure from linearity as ...

A considerable body of economic literature shows the adverse economic impacts of oil-price shocks for the developed economies. However, there has been a lack of empirical study of this kind on China and other developing countries. This paper attempts to fill this gap by answering how and to what extent oil-price shocks impact China’s economy, emphasizing on the price transmission mechanisms. To...

A remarkable feature of the crude oil market is a dramatic rise in oil price volatility over time which has been accompanied by a substantial fall in oil production volatility. We investigate the sources of this opposite evolution of both oil market variables. Our main …nding is that the observed volatility puzzle can be rationalized by the fact that the price elasticities of both oil supply an...

Should a central bank accommodate energy price shocks? Should the central bank use core inflation or headline inflation with the volatile energy component in its Taylor rule? To answer these questions, we build a dynamic stochastic general equilibrium model with energy use, durable goods, and nominal rigidities to study the effects of an energy price shock and its impact on the macroeconomy whe...

Carnitine palmitoyltransferase (CPT)-I catalyses the transfer of long-chain fatty acids from CoA to carnitine for translocation across the mitochondrial inner membrane. Expression of the 'liver' isoform of the CPT-I gene (CPT-Ialpha) is subject to developmental, hormonal and tissue-specific regulation. To understand the basis for control of CPT-Ialpha gene expression, we have characterized the ...
