Effect of Exchange Rate Misalignment on Bilateral Trade Between Kenya and European Union: 2000-2016

The exchange rate is an important variable in international trade because a country's competitiveness is determined by the expectations on how trade reacts to its movements. To orient the economy outwards, Kenya has pursued various measures from the 1990s to the 2000s. Kenya also signed up for nonreciprocal trade with the European Union under the Cotonou agreement. Despite the export-oriented efforts, Kenya's trade has remained skewed towards imports and a widening trade deficit which seems to follow the weakening of the Kenya shilling. The main policy dilemma therefore, is how imports accelerated in an environment of unhindered European Union market access, hence the motivation of this study. The study adopted a dynamic modeling approach since previous and present values affect exchange rate and trade. The results show that the economic fundamentals drive the real exchange rate. In terms of misalignment, the exchange rate is overvalued to a maximum of 5.9 percent and undervalued up to 5.2 percent. The estimated misalignment hurts imports but has a positive, statistically insignificant effect on exports. The results of this study suggest that the monetary authority should ensure the exchange rate remains stable and within the 6 percent range while monitoring all the underlying determinants. Additionally, hedging instruments should be made available and affordable to traders.

The Impact of Currency Misalignment on Trade Balance of Emerging Market Economies

This study is an attempt to examine the impact of currency misalignment on the trade balance of emerging market economies from 1980 through 2016. It firstly measures the equilibrium RER and corresponding misalignment series of 21 EMEs separately adopting a single equation approach and then includes them in the trade regression together with undervaluation and overvaluation to estimate the dynamic relationship between the trade balance and real exchange rate misalignment employing the system generalized method of moment estimation approach. The study suggests that, being a composite series of undervaluation and overvaluation, higher real exchange rate misalignment helps recover trade imbalances. It also identifies that undervaluation improves trade balance, while overvaluation cuts it down. The study identifies that the misalignment series of RER for most of the EMEs are substantially dominated by overvaluation episodes, and hence the opposing impact of undervaluation and currency misalignment on the trade balance of EMEs is not surprising. From the policy perspective, competitiveness achieved through currency movements helps emerging market economies not only to improve trade balance but also to withstand vulnerability that arises from huge external borrowings creating a strong external payment position.

Purchasing Power Parity Approach to Exchange Rate Misalignment in Nigeria

This study examines the purchasing power parity (PPP) approach to the determination of exchange rate misalignment in Nigeria by using two variants of the PPP: the absolute PPP (aPPP) and the relative PPP (rPPP). Data on the Nigerian Naira to US Dollar ( N/$), British Pound ( N/£) and Chinese Yuan (N /¥) interbank exchange rates, Nigeria consumer price index and Inflation as well as the US, UK and China consumer price indices and inflation rates spanning 2008:M1 to 2018:M12 were utilized. A recently modified fractional cointegration framework was employed, taking care of smooth structural breaks and nonlinearity, while the unit root tests employed the fractional alternatives. The results confirmed that the aPPP approach to exchange rate determination is unrealistic but revealed empirical support for the rPPP approach. Furthermore, the exchange rates computed with the rPPP approach show that the interbank Naira to US Dollar, UK Pounds and Chinese Yuan exchange rates were overvalued in most of the period of this study. The period of undervaluation observed in June 2016 and April 2017 coincided with the periods when CBN introduced the investors and exporters window. The study recommends the use of rPPP for gauging the level of exchange rate misalignment in Nigeria and suggests the need to diversify the export base to appreciate the exchange rate.

THE ASYMMETRIC IMPACT OF RER-MISALIGNMENT ON ECONOMIC GROWTH: AN APPLICATION OF HODRICK–PRESCOTT FILTER TECHNIQUE

Previous studies that examined the impact of exchange rate misalignment on economic growth were based on the symmetric approach where both overvalued and undervalued exchange rates were supposed to affect the economic growth in a similar way. However, in recent years, a number of studies have established that exchange rate changes affect the trade flows in an asymmetric way. Hence, this study investigates the asymmetric effect of exchange rate misalignment on the economic growth of Pakistan. The findings of the study indicate that in the case of the symmetric approach, exchange rate misalignment has a negative impact on economic growth. However, after applying the nonlinear ARDL approach, the study finds significant evidence in favor of the asymmetric effect of exchange rate misalignment on economic growth. Interestingly, the results indicate that undervaluation spurs while over-valuation hampers the economic growth in Pakistan. The study recommends that though under-valued exchange rate may have temporary relief for the economy, yet in the long run, a market-based equilibrium exchanger rate is imperative for a developing economy like Pakistan.
