In this paper, we examine the issue of volatility for both official and black market exchange rates of the Turkish lira using the monthly exchange rate against the US dollar for the period 1969-1998. The main findings are: 1) conditional shocks have a positive effect on exchange rate volatility;...

This paper re-examines the Purchasing Power Parity (PPP) hypothesis in which the endogenously determined break points are incorporated in thirteen major Middle East and Northern Africa (MENA) countries by using official and black market exchange rates data over 1970-1998. We utilize Lagrange...

In this study, the validity of Purchasing Power Parity (PPP) hypothesis is investigated by using unit root test on official and black market exchange rates for Turkey. When we used the classical unit root test, we found poor evidence for the validity of PPP in classical PP test but no evidence...

Recent debates about renewable energy consumption manifest two main expectations. Firstly, renewable energy consumption should contribute to economic growth and secondly, it should not cause damage on environment. This study focuses on the first issue by applying Toda–Yamamoto procedure and...

Departing from previous literature, using bootstrapped autoregressive metric causality approach which is more robust against non-stationarity and break problems than lag augmented tests, this study analyzes causal relation between economic growth and energy consumption in the Next 11 countries....
