The behavior of exchange rates has been an important issue in the international finance literature. Although exchange rate is erratic and unpredictable in the short run, its long-run behavior is believed to be guided by economic fundamentals. This paper empirically tests the long-run determinants of the exchange rate by focusing on the Taiwan/US case. After incorporating productivity differential, foreign reserves, and monetary base in the absolute Purchasing Power Parity (PPP) proposition, where the relative price is the only determinant of the exchange rate, the Johansen's maximum likelihood test results indicate these determinants and the exchange rate are indeed cointegrated: thus a long-run relationship can be established.

The main focus of this paper is to measure the speed of adjustment of the exchange rate by means of the persistent profile approach developed by Pesaran and Shin (1996) to examine the symmetry and proportionality assumptions of the purchasing power parity (PPP) theory of exchange rates for the Pak-rupee vis-à-vis the US-dollar exchange rate over the period 1982Q2-2005Q4. Using cointegration and vector error-correction modeling approaches, we find considerable support for the validity of weak-form PPP in Pakistan. Furthermore, the symmetry and proportionality assumptions of PPP are not verified. In the short-run, the exchange rate and foreign prices play a significant role in the convergence process to achieve long-run equilibrium. However, the speed of adjustment is very slow and the persistence profiles suggest that almost 4-5 years are required to eliminate deviations and bring the nominal exchange rate in line with the long-run equilibrium path.

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.

Exchange Rate Changes

Purchasing power parity (PPP) is an old and controversial proposition in economic literature. It is based on the law of one price, which argues that, after adjusting for the exchange rate, domestic and foreign price levels are equal. The relative version of PPP argues that exchange rate changes depend on the differential between domestic and foreign inflation rates. The absolute PPP version is based on restrictive assumptions that prevent it to hold in the short run. However, several studies support the validity of the relative PPP proposition in the long run. It is often observed that countries with persistently high inflation experience weak currencies. Our empirical testing using impulse response functions derived from a VAR model for eight countries provide mixed results. In six out of eight selected countries, relative PPP is supported by data in the long run.

The Exchange Rate

This paper attempts to empirically validate the Purchasing Power Parity (PPP) theory in the context of Sierra Leone. To achieve this objective, cointegration and error correction techniques were utilized to account for both long and short-run dynamics over the period 2007Q1 to 2019Q1. The Engel-Granger cointegration technique was utilized to ascertain the long-run relationship between the exchange rate and the price differential between Sierra Leone and the United States of America, while the redundant variable test was used to attain the parsimonious short-run error correction model. The results indicated a cointegrating relationship, while the coefficient on the price differential was greater than one (1), reflecting that the PPP does not hold for Sierra Leone. Moreover, the short-run results showed a rejection of the theory and rather endorses the presence of depreciation inertia, where past depreciation of the exchange rate is a major determinant of its current depreciating trend.

Relative Ppp

Relative purchasing power parity (PPP) holds for pure price inflations, which affect prices of all goods and services by the same proportion, while leaving relative prices unchanged. Pure price inflations also affect nominal returns of all traded financial assets by exactly the same amount. Recognizing that relative PPP may not hold for the official inflation data constructed from commodity price indices because of relative price changes and other frictions that cause prices to be “sticky,” we provide a novel method for extracting a proxy for realized pure price inflation from stock returns. We find strong support for relative PPP in the short run using the extracted inflation measures.

Purpose This paper aims to empirically examine the long- and short-run relationship between macroeconomic indicators (exchange rates, interest rates, exports, imports, foreign reserves and the rate of inflation) and sovereign credit default swap (SCDS) spreads for Pakistan. Design/methodology/approach The authors apply the autoregressive distributed lag (ARDL) model to explore the level relationship between the macroeconomic variables and SCDS spreads. The error correction model is estimated to examine the short-run effects of the underlying macroeconomic variables on SCDS spreads. Finally, the long-run estimates are obtained in the ARDL framework. The study uses monthly data covering the period January 2001-February 2015. Findings The results indicate that there is a significant long-run relationship between the macroeconomic indicators and SCDS spreads. The estimated long-run coefficients reveal that both the interest rate and foreign exchange reserves are significantly and negatively, whereas imports and the rate of inflation are positively related to SCDS spreads. Yet, the results suggest that the exchange rate and exports do not have any significant long-run impact on SCDS spreads. The findings regarding the short-run relationship indicate that the exchange rate, imports and the rate of inflation are positively, whereas the interest rate and exports are negatively related to SCDS spreads. Practical implications The results suggest that State Bank of Pakistan should design monetary and foreign exchange rate polices to minimize unwanted variations in the exchange rate to reduce SCDS spreads. The results also suggest that it is incumbent to Pakistan Government to improve the balance of payments to reduce SCDS spreads. The findings also suggest that the inflation targeting policy can also help in reducing SCDS spreads. Originality/value This is the first study to examine the empirical determinants of SCDS spreads for Pakistan. Second, it estimates the short- and long-run effects in the ARDL framework. Third, it considers both internal and external empirical determinants of SCDS spreads.

Background: Remittance has a crucial role in external sector stability, poverty eradication, and social as well as the human development of developing countries like Nepal. The determinants of remittance are widely discussed in the existing works of literature from altruism and portfolio approaches. Since the share of remittance in the current account, current transfer income, and forex reserve is significantly high, the study of major determinants of increasing remittance inflow is necessary. In this regard, this paper examines the relationship between remittance inflow, exchange rate, and workers outflow in Nepal. Objective: The main objective of this study was to examine the effect of the exchange rate and workers outflow on the remittance inflow of Nepal. Methods: This study employs the ARDL approach to co-integration to examine the relationship between remittance inflow as an endogenous variable and exchange rate and workers outflow as exogenous variables. Results: The coefficients of the exchange rate and workers outflow are significant and positive in long run as well as in the short-run whereas coefficients of the first lag value of workers outflow and remittance inflow itself are significant but negative. Conclusion: The significant and positive coefficient of exchange rate indicates that depreciation of Nepalese currency with US dollar (or rise in the exchange rate) rises the remittance inflow. Further, the remittance inflow also increases with an increase in workers outflow. The effect of the exchange rate on remittance is greater than that of workers outflow in both the long-run and short-run.

The Interest Rate

Exchange rate is a price of traded goods in the world market. To maintain the commodities competitive in the market, exchange rate should be adjusted according to the change in prices. If it is adjusted accordingly, then we say that purchasing power parity (PPP) holds in that country. However, phenomenon of PPP is completely kicked out under floating exchange rate regime in the short run [see for example, Rogoff (1999); Mark and Choi (1997); MacDonald (1999); Obstfeld and Taylor (1997); Coleman (1995); O’Connel (1998) and Michael, et al. (1997)]. Recent statement by the President of the National Bank of Pakistan, that the exchange rate and the interest rate are two faces of the same coin [Bokhari (2004)], shows that the changes in the exchange rate is strongly associated with the changes in the interest rate differential.1 It is also argued that under free float the value of currency is determined by demand and supply of foreign exchange and to control the value of currency using open market operations interest rate is used as the key monetary policy tool. Moreover, deterioration of trade balance leads to deprecation in exchange to make the exports competitive in the market and vice versa.

Relative population growth affects relative prices through the so-called Balassa–Samuelson (BS) mechanism and that in turn impacts PPP. This paper empirically investigates the relationship between the PPP exchange rate and relative population growth in a panel of 80 selected countries. Following the BS hypothesis, this paper argues that relative population growth affects nominal wages that impact price levels and thereby impacts PPP. Using panel cointegration and fully modified ordinary least square (FMOLS), the empirical results show that there is a stable relationship between PPP exchange rate and relative population growth in the long run. These empirical findings suggest that population growth have an important role in exchange rate determination through PPP.
