Purpose This study aims to investigate the contingent roles real effective exchange rates (REERs) play in mediating the effects of oil revenue on the agriculture sector value-added in 25 major and minor oil-exporting (MIOEC) countries during the period of 1975–2014. Design/methodology/approach The panel autoregressive distributed lag (ARDL) estimator proposed by Pesaran et al. (1999) was relied upon to achieve the objectives of the study. This estimator involves a pool of small cross-sectional units over a long-time span that covers for 25 oil-exporting countries over 39 years (1975–2014). Findings This paper reveals the following findings. Firstly, oil revenue has a direct negative effect on agricultural value-added in the short- and long-term. This finding holds for full sample and subsamples of major oil-exporting (MAOEC) and MIOEC countries. Further assessment reveals that the magnitude of the impact is larger for MAOEC than that of the MIOEC. Secondly, the finding for the long-run effect shows that the contingent effect of real exchange rate on the nexus between oil revenue and agricultural value-added is negative and statistically significant at the conventional level for the full sample. This suggests that, in the long-run, the appreciation in real exchange rates exacerbate the negative marginal effects of oil revenue on agricultural value-added in all oil-exporting countries. However, when sub-samples of MAOEC and MIOEC are considered, the contingent effect disappeared (become insignificant) in MAOEC while it is positive and statistically significant in MIOEC. Thus, in the long-run, the appreciation in real exchange rates diminishes the negative marginal effects of oil revenue on agricultural value-added in MIOEC. While oil revenue has a direct negative effect, its effect is also moderated by the variations in REERs in MIOEC in the long-run. Finally, in the short-run, fluctuations in the real exchange rate do not matter for the nexus of oil revenue and agriculture sector in these countries whether minor or MAOEC countries. Originality/value This study contributes to the debate in the empirical literature on the Dutch disease effect and “oil curse”. Using the appropriate panel ARDL empirical framework, it provides evidence on how exchange rate variations in the oil-exporting countries influence the nature of the effects of the oil revenue on agricultural sectors in the long-run but not in the short-run. Contingent effects of REERs only appear to exist in MIOEC in the long-run.

Real exchange rate is an important indicator of competitiveness in the foreign trade of a country. Any changes in real exchange rates would therefore lead to fluctuations in capital flows. It is therefore important to align real exchange rates within the equilibrium levels to avoid negative consequences on the economy. This study sought to understand the determinants of real exchange rate alignment in Kenya using annual data from 1988 to 2019 using Autoregressive Distribution Lag (ARDL) model. The study estimated the long run and short run dynamics of real exchange rate alignment in Kenya. The ARDL bounds test confirmed that a long run relationship exists between real exchange rate and the explanatory variables. Real exchange rate was the dependent variable while the explanatory variables were external public debt, government expenditure, interest rate differentials and productivity differentials. The results revealed that external public debt, government expenditure and productivity differentials are significant determinants of real exchange rate alignment. Interest rate differential was found to be not significant. The Error Correction Model was found to be significant and having the right (negative) sign. This shows that Kenya’s real exchange rate adjusts to the long run equilibrium as a response short run shocks of previous periods. The speed of adjustment was found to be 86 percent per year. Both the long run and error correction models were found to be stable as per the CUSUM and CUSUMQ tests. The models also passed all the diagnostic tests including serial correlation, normality, heteroscedasticity, and multicollinearity.

This study examines the long-run and the short-run relationship between the real exchange rate, GDP, FDI, inflation (INF), gross capital formation (GCF), Net official's development assistance (NODA), GNI, and trade balance in Uganda for the period 1994-2018. We used an Augmented Dickey-Fuller (ADF) test for the stationarity test, and we use the Johannsen cointegration approach to prove the existence of cointegration. The ADF tests show that the series was non-stationary in level but became stationary after the first difference. The Johannsen cointegration test indicates the long and short-run relationship between all the explanatory and trade balance in Uganda. Under such circumstances, a Vector Error Correction Model (VECM) is employed since the results offer more information than other data generation processes. Our findings are as follows: Real exchange rates, FDI, GCF and have a positive relationship with Trade balance. It means that Uganda can depreciate the Exchange rate to improve its Trade balance. The results proved the J-Curve effect's existence (i.e., the long-term impact of exchange rate on trade balance). The recommendations from this study are - Uganda's monetary policy management should emphasize more efforts on the stability and minimization of the volatility of exchange rates of the shillings since its movements affect international prices both negatively and positively, leading to either a decline or trade boost.

PurposeThe aim the study is to explore the impact of real exchange rate volatility and other macroeconomic variable such as price of import, industrial production and real exchange rate on 45 import commodities, considering global financial crisis period on India's import from the US. The empirical analysis at disaggregate level of import indicates the existence of both short-run and long-run effect in one-third importing commodities. The results show both positive and negative effect and causality among variables.Design/methodology/approachThe study uses E-GARCH model to gage the real exchange rate volatility, an autoregressive distributive lag (ARDL) bound test technique to discover the adequate short- and long-run relationships and Toda-Yamamoto causality method to analyze the causality among variables. The study uses the time period from 2002:M09 to 2019:M06.FindingsThe empirical analysis at disaggregate level of import indicates the existence of both short-run and long-run effect in one-third importing commodities. The results show both positive and negative effects and causality among variables.Practical implicationsThe finding of the study suggests that macroeconomic variables have significant role and could be important to undertake the small and medium scale industries in policymaking. Government may need to make decision for micro, small and medium enterprises (MSMEs) as their performance can bring change in the trade to compete globally by increasing and controlling the price of the import and defending the domestic competitiveness.Originality/valueThe study uses additional variable namely price of import and includes the global financial crisis period to measure dampening effect on each commodity by using robust econometric technique in context of emerging nation like India.

The role of exchange rate policy in economic development has been the subject of much debate and controversy in the development literature. Interest rates and exchange rates are usually viewed as important in the transmission of monetary impulses to the real economy. In the short run the standard view of academics and policy-makers is that a monetary expansion lowers the interest rate and rises the exchange rate, with these price changes then affecting the level and composition of aggregate demand. Frequently, these influences are described as the liquidity effects of monetary expansion, viewed as the joint effect of providing larger quantities of money to the private sector. Popular theories of exchange-rate determination also predict a link between real exchange rates and real interest rate differentials. These theories combine the uncovered interest parity relationship with the assumption that the real exchange rate deviates from its long-run level only temporarily. Under these assumptions, shocks to the real exchange rate—which are often viewed as caused by shocks to monetary policy—are expected to reverse themselves over time. This study investigates the long-run relationship between real exchange rates and real interest rate differentials using recently developed panel cointegration technique. Although this kind of relationship has been studied by a number of researchers,1 very little evidence in support of the relationship has been reported in the case of developing countries. For example, Meese and Rogoff (1988) and Edison and Pauls (1993), among others, used the Engle-Granger cointegration method and fail to establish a clear long-run relationship in their analysis.

Purpose The purpose of this study is to examine the temporal relationships between inflation and exchange rate changes and their implications for the trade balance in Uganda, which saw persistent trade deficits, rising inflation and disinflation episodes, as well as significant exchange-rate realignments and other liberalization measures over the sample period considered. Design/methodology/approach The short-run dynamics of the variables in question and the pattern of their long-run relationships are examined applying the bounds testing approach to cointegration on quarterly data. Findings The estimates suggest that, in the long run, a real depreciation leads to an increase in inflation; and that both real depreciation and inflation exert no significant effect on the trade balance. The estimated short-run dynamics suggest a causal relationship between the trade balance and the real exchange rate and between the real exchange rate and inflation, which is also found responsive to developments in the foreign sector. Taken together, the short-run and long-run multipliers seem to provide a weak support for the J-curve effect, while no evidence is found for the presence of the S-curve effect. Originality/value The study sheds light on the relationship among real exchange rate, inflation and the trade balance in the context of a small developing economy; it highlights that an improvement in the trade balance requires more than an appropriate exchange rate policy and underscores the importance of other policies in strengthening the external sector of the economy.

The focus of this study was on investigating the response of tobacco exports to real exchange rates and real exchange rate volatility and other factors in Zimbabwe using secondary data spanning from 1980 to 2019. Bilateral nominal exchange rates and time-variant weights of Zimbabwe’s 10 major trading partners were calculated and used to compute the real exchange rate index. The time-dependent weighting system was used to better represent the evolution of trade patterns in the index. The arithmetic method was employed for computing the index. Generalized autoregressive conditional heteroskedasticity (GARCH) and autoregressive conditional heteroscedasticity (ARCH) models were used to generate the real exchange rate volatility index. The export response function was adopted as the tobacco exports response model. The variables in the tobacco exports response model were the realworld Gross Domestic Product (GDP), real exchange rate, terms of trade, real exchange rate volatility and dollarization. A vector error correction model (VECM) was used to estimate the response of tobacco exports to real exchange rate, real exchange rate volatility and other factors. The VECM results indicated that real world GDP was insignificant in both the short and long run. In the long run, the real exchange rate appreciation had a negative impact on tobacco exports. Conversely, in the short run, the depreciation of real exchange rate had a positive impact on tobacco exports. Hence, the government has to adopt other mechanisms that reduce uncertain movements of exchange rates.

PurposeThis paper aims to examine the effects of exchange rate volatility on consumption by focusing on a small open sub-Saharan Africa (SSA) country, Ghana, which has experienced exchange rate volatility frequently.Design/methodology/approachThe authors used annual data covering the period 1980-2015, the annualised variance of the real exchange rate as a measure of exchange rate volatility and a technique that is able to separate short-run effects from long-run effects.FindingsThe authors found that exchange rate volatility has negative effects on domestic consumption in the short run, which is passed on as negative long-run effects. This conclusion is unaffected by an alternative measure of exchange rate volatility and the choice of lag restrictions.Research limitations/implicationsThe authors’ finding suggests that policymakers should seek to reduce or prevent exchange rate volatility by pursuing various policies including limiting foreign currency transactions within the country and promoting quality exports.Originality/valueThe extant studies have examined the effects of exchange rate volatility on consumption by considering countries in regions other than SSA. This paper focuses on a small open SSA country which has experienced exchange rate volatility frequently. Unlike most studies, this paper differentiates short-run effects from long-run effects.

Purpose This study aims to make a comparative study of the applicability of the purchasing power parity (PPP) in selected less developing countries (LDCs) on one hand and European countries on the other hand. Design/methodology/approach The research design is empirical and ex post facto. This study uses an assortment of co-integration tests and error correction representation. The chosen approach allows for the consideration of long-run elasticities and the dynamics of the short-run adjustment of exchange rates to changes in domestic and foreign prices. Monthly data are used for the period 1980:1 through 2015:12 (i.e. 432 observations). Findings Results from long-run co-integration analysis, short-run error correction models and persistence profile analysis overwhelmingly confirm the validity of PPP in these two sets of countries regardless the disparity in their relative exchange rate and price characteristics. Research limitations/implications Curiously, several of these empirical studies and still many more, have focused their attention on the experiences of industrialized countries, with a few investigations devoted to LDCs. The evidence is even scarcer in Africa. Clearly, the acceptance of any hypothesis as a credible explanation of economic reality hinges on the robustness of the hypothesis across countries with different economic and institutional frameworks. Practical implications Knowledge of the extent to which exchange rate and relative prices can be linked in the long run is important for the design and management of inflation and the implementation of monetary policy. For instance, policy actions aimed at stabilizing the domestic economy can obtain results that are, at best, uncertain in the absence of correct characterization of the PPP dynamics. Moreover, structural and macroeconomic adjustment programs implemented in these countries to achieve economic growth and external competitiveness could be unsuccessful if flawed estimates of PPP exchange rates are retained. Originality/value Several empirical studies have been done to prove the validity or otherwise of the PPP. Unlike prior authors, this study makes a comparative study of the applicability of the PPP in selected LDC on one hand and European countries.

Abstract Standard finite horizon tests uncover only weak evidence of the predictive power of the real exchange rate for excess currency returns. On the other hand, in long-horizon tests, the real exchange rate strongly and negatively predicts future excess currency returns. Conversely, we can attribute most of the variability in real exchange rates to changes in currency risk premiums. The “habit” and “long-run risks” models replicate the predictive power of the real exchange rate for excess currency returns, but substantially overstate the fraction of the volatility of the real exchange rate due to risk premiums. Received December 14, 2017; Editorial decision October 14, 2018 by Editor: Raman Uppal. Authors have furnished an Internet Appendix, which is available on the Oxford University Press Web site next to the link to the final published paper online.

The present study investigates the impact of human capital, knowledge capital which is a function of human capital, and real exchange rate scenario in explaining long-run industrial total factor productivity (TFP) from 1980 to 2015 on the theoretical basis of the open endogenous growth model. The variables employed in the contemporary study include manufacturing value added (MNVA) as industrial output measure, gross fixed capital formation (GFCF) as a measure of capital and labour input which is measured using employment data. Gross enrolment ratio (GER) is taken as a measure for human capital formation, expenditure on research and development (R&D) as a proxy for knowledge capital, and real exchange rate indicates global economic shocks. The study involves estimating TFP for Industrial Sector during the post-liberalization period by employing Cobb-Douglas production function. The ARDL bounds test technique for cointegration revealed long-run relation among the varying factors studied. The Toda-Yamamoto causality test concluded bi-directional causality running between, R&D expenditure and Industrial TFP which sends a strong signal to the policymakers for a well-framed long-term integrated approach for human & knowledge capital formation which will act as a strong impetus for manufacturing firms to come up in terms of augmenting production and productivity and expanding foreign market horizon.
