abstract t he return of capital is fundamental to the intertemporal allocation of resources by changing the consumption behavior and capital accumulation over time. taxation on return of capital increases the marginal product of capital, meaning that capital stock is lower than when capital is not taxed, which results decreased growth and welfare in steady state. this paper studies the impact o...

abstract i n this paper, we investigate the existence and the nature of real exchange rate misalignment in organization of the petroleum exporting countries (opec). to do this we estimated a cross country basic real exchange rate determination model for 1990-2012 and extracted historic trend of misalignment. the results imply that all opec countries have had misalignment -of different kinds tho...

abstract in this study, we applied recently developed panel unit root and cointegration techniques to examine the long-run real income per capita and price elasticities for demand of electricity in selected middle east and north african (mena) countries using an annual data series from 1990 to 2011.our main finding from the panel analysis is that the demand for electricity is highly price elast...

The present investigation was undertaken to study the benefical effects of Coenzyme Q10 in streptozotocin (STZ)-induced type I diabetic rats. STZ-diabetes produced a significant increase in fasting glucose levels that was associated with decrease in serum insulin levels. STZ also produced hypercholesterolemia, hypertriglyceredemia, increase in lipid peroxidation and decrease in high density lip...

Todays, parallel to growing in acceptance of functional products, various additives are used to improve the characteristics of functional food products. The coenzyme Q10 is an essential component for energy conversion and production of adenosine triphosphate (ATP) in the membranes of all body cells and organelles, especially the inner mitochondrial membrane is found. Coenzyme Q10 plays a vital ...

This article adds technology choice to a free-entry Cournot model with linear demand and constant marginal costs. Firms can choose from a discrete set of technologies. This simple framework yields non-existence of equilibrium, existence of multiple equilibria and equilibria in which ex-ante identical ̄rms choose di®erent technologies as possible outcomes. I provide a full characterization of th...

An extract from the fruits of black pepper consisting of a minimum of 98% pure piperine was evaluated in a clinical study using a double-blind design. The relative bioavailability of 90 mg and 120 mg of coenzyme Q10 administered in a single-dose experiment or in separate experiments for 14 and 21 days with placebo or with 5 mg of piperine was determined by comparing measured changes in plasma c...
