Purpose – The purpose of this paper is to focus on whether the deviations from the cointegrating relationship possess long memory and the fractional cointegration analyses may capture a wider range of mean-reversion behaviour than standard cointegration analyses. Design/methodology/approach – This paper uses a fractional cointegration technique to test the purchasing power parity (PPP). Findings – The authors found that PPP held, but very weakly, in the long run between the Argentine, Brazil, Chile, Colombia, Indonesia, Korea, Mexico, Thailand and Venezuela and US exchange rate during our floating exchange rate period but that the deviations from it did not follow a stationary process. Nevertheless, it is also found that the deviations from PPP exists and can be characterized by a fractionally integrated process in nine out of 13 countries studied. Originality/value – The findings are consistent with the consensus of the empirical literature, reviewed earlier in this paper, on PPP between Argentine, Brazil, Chile, Colombia, Indonesia, Korea, Mexico, Thailand and Venezuela and the USA.

The Exchange Rate

The current study explores nonlinear cointegration as well as asymmetric adjustment to investigate the long-run purchasing power parity in three major trading partners of Pakistan. The ESTAR and LSTAR models were used to investigate the behavior of the nominal exchange rates. The findings declared that series follows the nonlinear exchange rate. The asymmetric behavior of the exchange rate allows the threshold cointegration model to be implemented. In the case of Pakistan-China, the result suggests that long-run PPP holds. As a result, trading will be more profitable if the exchange rate is varied in relation to major trading partners rather than just the US dollar.

For a small open economy of Pakistan, exchange rate is determined through the two alternative theories; the nominal theory of exchange rate named by Purchasing Power Parity (PPP) and the real theory known as Harrod Balassa Sameulson (HBS). According to the requirements of theories, two kinds of real exchange rate have been employed for the yearly data of 1972-2008. As, both of the theories are disputed at the ground of their long run relationship with real exchange rate, therefore, the VAR based Johenson Co-integration approach has been utilised to see the long run relationships. PPP has shown less satisfactory results either in its form of absolute version or relative version. Because, real exchange rate in Pakistan is a non-stationary process by Augmented Dickey Fuller unit-root test, predicting some pushing force behind the non-tradable sector. While favouring the PPP in tradable sector, the ADF and KPSS are indicating the presence of the HBS in Pakistan. On the other hand, the analysis of the HBS through co-integration is showing that relative productivity difference has an opposite relationship with relative non-tradable sector prices and with RER. However, the relationship between relative non-tradable sector prices and RER is much stronger and according to the theory. So, there have been incorporated some demand side and external factors to reduce the mis-specification of the simple HBS model. Therefore, in the extended HBS model, productivity difference, government consumption expenditure, terms of trade and world oil prices are appreciating the RER and money supply (a control variable) is pursuing depreciation in RER. So, these results yield some policy implications for Pakistan which can be useful for developing countries as well.

This paper tests if the efficient market version of Purchasing Power Parity (EMPPP) holds for the Mexican case for the 1970-2002 period in an environment of changing exchange rate regimes. Two regression analyses which extend PPP to a dynamic intertemporal model, based on market efficiency, are used, and in addition two unit root tests are applied. In general, the obtained empirical evidence does not support the EMPPP. Results suggest an inefficient market resulting from weak exchange rate policies and weak adoptions of several exchange rate regimes without proper inflation targeting and the application of strong and disciplined macroeconomic policies and structural changes.

The aim of this study is to identify : (1) profile of exchange rate and purchasing power parity of IDR against US $ based on Big Mac Index compared to the exchange rate of other countries, and (2) the position of the Big Mac Affordability of  Indonesia compared to other ASEAN countries. The results showed that based on Big Mac index during the period April 1998 up to January 2015, IDR exchange rate tends to be undervalued against the USA dollar. The cause of the currency tends to be in a position of undervalued due to the components of non-tradable have not been included in Big Mac index. The index of Big Mac Affordability indicates that there is a great disparity of income between Singapore and five other ASEAN countries. The purchasing power of the real income of the people in Singapore is nearly five times the real income of the people in Indonesia.

This study examines the long-run relationship between exchange rates and relative prices. We use a long memory techniques that allow for persistence of chock relationships across real exchange rate to examine the existence of weak-form and strong-form Purchasing Power Parity (PPP) between the Tunisian and five partner countries of Tunisia, namely, (Germany, the United States, France, Italy, the UK, Morocco and Libya. The empirical results obtained through the R/S, Modified R/S, GPH and ELW tests; make us consider the PPP as an event in the long run if significant short-term deviations from the PPP cannot exist. Therefore, the analysis of the fractional cointegration makes the deviations, regarding equilibrium, follow a slightly integrated process and therefore capture a much wider group of research parity or mean-reverting behavior.
