This study examines the relationship between energy consumption and economic growth in the Iranian economy. To that end, a wavelet transformation technique is used, which allows us to combine the time domain and frequency domain characteristics of two time series together. Using this approach and data for the period 1991:2 – 2017:1, this study tries to overcome the shortcomings of  standard eco...

    Energy is one of the factors used in most economic activities. The economic security of most countries depends on secure access to energy. Therefore, the production and consumption of energy and its optimal use are of particular importance. The purpose of this study is to investigate the relationship between energy consumption and economic growth in the framework of nonlinear self-regressi...
