Dynamic effects of shadow economy and environmental pollution on the energy stock prices: empirical evidence from OECD countries

This study investigates the dynamic effects of the shadow economy and environmental pollution on the energy stock prices in the case of the Organization for Economic Co-operation and Development (OECD) countries via generalized methods of moments (GMM) and during the years from 2004 to 2014. Results suggest significant links between the volume of shadow economies, energy stock prices, and environmental pollution. Negative effects of carbon dioxide emissions on energy stock prices are found in this study. Furthermore, a U-shaped relationship is also found between the shadow economy and energy stock prices; that is the initial levels of the shadow economy the response of energy stock prices is negative; then, beyond a trough point, its response starts to be positive at the further stages of the level of shadow economies. Despite energy consumption raises energy stock prices, environmental pollution mitigates the value of energy stock prices.
