بازنگری بلندمدت برابری قدرت خرید با تنظیم نامتقارن برای کشورهای G-7

In this study, we applied a threshold cointegration test advanced by Enders and Siklos (2001) to investigate the properties of asymmetric adjustment on long-run purchasing power parity (PPP) in G-7 countries between January 1994 and April 2010. Although there was strong evidence of long-run PPP for these G-7 countries, with the exception of Canada, the adjustment mechanism was asymmetric. These results have important policy implications for G-7 countries.
