Relative GDP shares are frequently used as weights in aggregations. In order to ensure that these weights reflect countries’ shares in real output, GDP data in national currencies should be converted into a common numeraire currency at purchasing power parity (PPP) rates. A review of the...

The concept of purchasing power parity (PPP) is used to evaluate whether eight East Asian currencies were overvalued on the eve of the 1997 crises. The Johansen and Horvath-Watson cointegration test procedures are applied to bilateral and multilateral exchange rates, deflated using CPIs,...

This paper tests the hypothesis of 'commodity currency' on the nuevo sol and, more generally, identifies the drivers of Peru's equilibrium real exchange rate using a cointegration analysis. The results show that export commodity prices do not have a statistically significant impact on Peru's...

The use of purchasing power parity as a basis of fixing exchange rates among industrial countries, as proposed by McKinnon, is discussed and contrasted with alternative interpretations of the PPP doctrine. Major policy implications of such a regime are emphasized. Furthermore, a new technique...

This paper reviews recent developments in the exchange system in the Islamic Republic of Iran and in the real effective exchange rate (REER). It also considers the determinants of the REER in connection with the choice of exchange regime after unification. The study illustrates how economic...

Exchange rate-based inflation stabilization (ERBS) policies are associated with a boom-recession cycle in economic activity and sustained real exchange rate appreciation. A class of models in the literature has explained these empirical regularities with the lack of credibility of the...

The consequences of large depreciations on economic activity depend on the relative strength of the contractionary balance sheet and expansionary expenditure switching effects. However, the two operate over different time horizons: the balance sheet effect hits almost immediately, while...

The number of studies attempting to estimate the ""equilibrium"" real value of China''s currency has proliferated in recent years as the country''s presence in world markets has grown. These studies have sought to establish whether or not a significant part of China''s competitive prowess can be...

The paper explores how international integration through global value chains shapes the working of exchange rates to induce external adjustment both in the short and medium run. The analysis indicates that greater integration into international value chains reduces the exchange rate elasticity...
