D’Alessandro’s (2010) model investigates the impact of total government spending on private consumption but according to Barro’s (1981) suggestion, the impact of two groups of government spending on private consumption can be studied separately. The fist group produces utility affecting services for household and the second group is as an input in the private production process. So in the pre...
energy as an important production factor has significant effects on economic growth. identifying the relationship between energy and economic growth can help to improve governmental energy policies. applying ardl and ecm methods, this paper examines the longrun and shortrun causality relationships between (1) energy consumption and economic growth and (2) energy consumption and employment in va...
The identification of the most important factors affecting energy intensity with the aim of controlling and managing energy consumption is an important topic. Findings of different empirical studies on the factors affecting energy intensity are inconsistent and this raises uncertainty about the employed models. One of the techniques that conform to these uncertainty conditions of the model is t...
the present paper investigates the effect of production factors, including technology, physical capital and labour on the energy consumption intensity of iran. for this purpose, time series data during the period of (1974-2007) have been analyzed within cobb–douglas production function framework. the results of the study indicate that the technology and the physical capital have caused the aver...
IIn this study, the effect of different levels of Scrophularia striata extract on the parameters of laboratory gas production, the concentration of volatile fatty acids and the activity of hydrolytic enzymes on the contents of the cecum of adult male rabbits were investigated. For this purpose, 20 New Zealand rabbits weighing approximately 1.6 ± 0.2 kg (5 months and up) were used in a completel...
