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.

Purpose: This study is aimed at to observe the purchasing power parity (PPP) Theory. The purchasing power parity (PPP) is the most enduring debate of literature in international macroeconomics. It is most controversial due to various puzzles and tested with different econometric models for certain group of countries. Therefore, the PPP is valid assumption while international comparison due to use of common exchange rate and the prevalence of Law of One price. Design/Methodology/Approach: The validity of PPP for relative countries (Pakistan, China, Iran and Turkey) was tested and analyzed for the sample period 2001 to 2018. Findings: It is observed that exchange rates of Pakistan, China, Iran and Turkey are not consistent and constant. The deviations of PPP through structural changes identified and are not persistence over long period. Overall results reflected that there is an existence of long run equilibrium relation in between Pakistan and China as well as in between Iran and Turkey. The error correction model has confirmed the adjustment speed of short run disequilibrium to long term disequilibrium level.  Implications/Originality/Value: The expected differential level of inflation has significant positive impact to exchange rate shift to Pakistan and trading activity patterns. The changes in foreign exchange market and commodity market due to economic integration are important implications for   economic globalization.

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.

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.

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.
