Growing energy demand but stagnant production followed by volatile exchange rate leads Pakistan to energy imbalances and potential economic contraction. Yet, studies on sectoral energy imports are limited and inconclusive without accessing the asymmetric effect of currency fluctuations. We examine the impacts of Pakistani rupee volatility on monthly energy imports based on the nonlinear autoregressive distributed lag (NARDL) estimations. Augmented Dickey–Fuller and Phillips–Perron tests were used to conduct unit root testing, and the bound testing approach was used to examine the long-term cointegration. The long-run asymmetry was tested with the Wald test, and using the NARDL model, we examined both short-run and long-run asymmetric effects of exchange rate volatility on energy imports. The bound test was established and supported through ECMt−1 (t-test), cointegrating the relationship between exchange rate volatility and energy imports in a long term. Among others, both short-run and long-run asymmetric effects were found for crude oil, coal, electricity, and petroleum products. Rupee depreciation increased crude oil and electricity imports, while the appreciation effects were insignificant. Overall, the empirical assessment reveals that the foreign exchange volatility effect is sectoral specific and asymmetric in Pakistan. It offers new insights into re-strategizing the energy policy and refining the import substitution plan.

The Impact

Purpose – The purpose of this paper is to empirically investigate the role of real effective exchange rate (REER) volatility on export volume and also to address the impact of the international financial crisis of 2008. Design/methodology/approach – The empirical methodology is based on System GMM estimation for a set of 106 countries for the period of 2000-2011. Findings – For the complete sample of countries and for a set of developing/emerging economies, there is evidence that an increase (decrease) in REER volatility reduces (increases) export volume. The results are not robust once the oil export countries are removed from the sample. The estimated coefficients for the financial crisis dummy are positive and statistically significant, indicating that export volume were 0.14 percent higher after the financial crisis of 2008 compared to the previous period (2000-2007). There is also evidence that the export volume is price (REER) and income (trade weighted) inelastic. Research limitations/implications – The empirical results are valid for the complete set of countries and for developing and emerging economies when including the oil export countries, suggesting that countries should reduce exchange rate volatility in order to foster their export volume and that oil export countries have an important role on these results. Practical implications – The paper suggests that policymakers should adopt different policies to minimize exchange rate volatility if they seek to increase export volume. The international financial crisis had a significant impact on export volume in all estimated models regardless of the set of countries used. Originality/value – One of the main novelties of this work is that it deals with possible endogeneity using GMM estimators and addresses the issue of instrument proliferation, which is not a common feature of previous empirical studies on exchange rate volatility and trade flows. Another original aspect of the research is the construction of trade weighted variables for foreign income and REER based on the major 20 export partners for each country used in the panel data estimation. The work also incorporates the years following the international financial crisis of 2008, which is an additional empirical novelty, in order to address the impact of the international financial crisis on the export volume.

Effective Exchange Rate

This paper investigates oil revenue and exchange rate volatility and as well as their impacts on Nigerian economic growth which is examined from 1980 – 2010. Exchange rate volatility was captured using standard deviationof monthly nominal effective exchange rate. During this period, Nigeria recorded high levels of volatility (in oil receipt and effective exchange rate) as can be seen from the Autoregressive Conditional Heteroskedasticity (ARCH) and the General Autoregressive Conditional Heteroskedasticity (GARCH) - ARCH/GARCH results. Also, the Augmented Dickey-Fuller test indicate that some of the variables exhibit unit root, this research further makes use of vector autoregressive process (VAR) using the variance decomposition of Choleski factorisation in which forecast error variance of some systems of equations has innovations which is credited to each variable and the method of impulse response function. The authors established that exchange rate in Nigeria due to its volatility causes revenue volatility from oil and this has a daring consequence on Nigeria's economic growth (being a monoculture economy). They found that change in oil price index, change in interest rate, proportion of export to GDP and exchange rate variability bears some negative impacts on change in the rate of output growth in Nigeria. Moreover, government size and exchange rate variability created some disturbances to change in the rate of output, these changes were not as substantial as those created by change in interest rate, ratio of oil export to GDP and change in oil price index. In addition, change in output responds negatively for some time horizon to one-standard deviation shocks in change in oil price index, change in interest rate, oil export to GDP and exchange rate variability. The authors recommend economic diversification and sound macroeconomic management among others.

The Impact

The adoption of a flexible exchange rate system since 1986 in Nigeria has made the country witnessed varying rate of the naira vis-à-vis the U.S dollar. This paper examines exchange rate volatility with ARCH model and its various extensions (GARCH, TGARCH, and EGARCH) using quarterly exchange rate series from 1986-Q1 to 2014-Q4.The impact of exchange rate volatility on non-oil exports was also examined using Error Correction Model (ECM) with two different measures of volatility. The results obtained confirm the existence of exchange rate volatility and also found a significant negative effect on non-oil export performance in Nigeria. Therefore, the Nigerian government should ensure an appropriate policy mix that not only ensures a stable and realistic exchange rate but also conducive atmosphere for production and exportation.

The Impact

One remarkable importance of exports is that it enables countries generate the required foreign capital needed to drive sustainable growth and development. This is to say that export earnings are capable of increasing capital formation through real investment. This study therefore focused on the impact of exports to capital formation in Nigeria for a 40-year time period spanning from 1981 to 2020. Related works on the subject matter were reviewed. The unit root test showed that all the variables attained stationarity after first difference. The Johansen cointegration test result showed that there exists a stable long run relationship between gross fixed capital formation, oil export, non-oil export and exchange rate in the model. Using the ordinary least square (OLS) estimation technique in analyzing the data sourced, the results showed that oil export had a negative and insignificant impact on capital formation in Nigeria. Similarly, non-oil export and exchange rate exerted insignificant negative influences on capital formation in Nigeria for the period covered by the study. Based on the findings from the study, the following recommendations were made. First is that the proceeds from crude oil export should be used to acquire capital assets for investment which will in turn drive growth in the economy. Also the government through the central bank of Nigeria (CBN) and relevant agencies should pay more attention to the non-oil sector in terms of the implementation of favourable policies, grants and loans, tax incentives, research and development, etc. to improve the export of the sector, making it compete favourably in the international market. This is because crude oil is an exhaustible asset that is liable to depletion. Finally, efficient exchange rate policies should be implemented by government through the relevant authorities to protect the value of the naira while ensuring that the products are not too dare in the international market.

Abstract The paper seeks to assess the industry-based effect of exchange rate volatility on the export of non-oil sector in Nigeria. Theoretically and empirically, volatility-trade link is ambiguous. The paper employed bound test for co-integration between exchange rate volatility and exports of non-oil products. Empirically, the results show that we can accept the hypothesis of no co-integration between volatility and export of non-oil industries in most cases. Therefore, the study concludes that the exchange rate volatility can actually produce negative effect on non-oil export industries in the short-run especially the big industries (Agriculture, food and manufacturing) but this effect does not linger into the long-run and this suggests that most of these industries have been able to develop a mechanism to cope with exchange rate volatility problem in the long-run.

Exchange Rate Movements

As a mono-product economy, where the main export commodity is crude oil, volatility in oil prices has implications for the Nigerian economy and, in particular, exchange rate movements. The latter is particularly important due to the twin dilemma of being an oil exporting and oil-importing country, a situation that emerged in the last decade. The study examined the effects of oil price volatility, demand for foreign exchange, and external reserves on exchange rate volatility in Nigeria using monthly data over the period from May, 1989 to April 2019. Drawing from the works of Atoi [1] Having realized the potentials of an Autoregressive conditional heteroskedasticity (ARCH) model several studies have use it in modeling financial series. However, when using the ARCH model in determining the optimal lag length of variables the processes are very cumbersome. Therefore, often time users encounter problems of over parameterization. Thus, Rydberg (2016) argued that since large lag values are required in ARCH model therefore there is the need for additional parameters. Sequel to that, this research uses the ARCH-M to solve the challenges. The study reaffirms the direct link of demand for foreign exchange and oil price volatility with exchange rate movements and, therefore, recommends that demand for foreign exchange should be closely monitored and exchange rate should move in tandem with the volatility in crude oil prices bearing in mind that Nigeria remains an oil-dependent economy.
