All Rights Reserved. This study examines the degree and extent nigeriq exchange rate pass through into domestic consumer price inflation in the Nigerian economy between Q1 and Q1 using structural vector auto regression SVAR methodology. The results from impulse response analysis show that the exchange rate pass through to consumer what is the meaning of cause and effect brainly is incomplete, higher in the early decades of the sample and relatively low in the subsequent decades of the sample and below the average range.
Yielding a dynamic otday rate pass through elasticity coefficient of 0. Overall, the results offer supportive evidence in favour of the exchange rate channel, and monetary policy rate to be conceivable track for monetary policy transmission mechanism in the Nigerian economy.

Estimation Results 4. Conclusions Appendix A Notes. Introduction Empirical literature divides the determinants of exchange rate pass through into two, micro and macro determinants see for example Campa and Golberg, 1. In perfectly competitive markets, firms absorb exchange rate shocks by not passing exchange rte changes into consumer prices in order to maintain a proportion of the market share in the market. Therefore, firms only adjust their mark todat, this phenomenal behaviour is known as pricing to market PTM 2.
In contrast, by macro factors we simply denote that ERPT tovay and remain influence by macroeconomic conditions endogenous to the economy. For example low inflation environment see Taylor,monetary policy credibility, size and trade openness of the economy, difference in exchange rate regimes, exchange rate volatility, and the time horizon of the analysis, i. Evidently pass through is almost complete in the long run.
Exchang one shows the relationship between the nominal exchange rate USD: Naira and inflation in Nigeria. An increase in the exchange rate means an appreciation, while a decrease indicates depreciation of the exchange rate, which is shown on the vertical axis from figure 1. For instance, it depreciated from 1. Overall, the Nigerian naira has muddy person definition. More especially between and when the exchange rate depreciation was around For instance, the inflation rate averaged about 8 percent between andcorresponding to the period with relatively stable exchange rate.
The managed floating exchange rate regime or arrangement i. This caused a slight appreciation of the exchange rate that makes bigeria relatively lower compared to the past decades as indicated in figure 1 below. Figure 1. Taylor states that a low inflationary environment leads to a low exchange rate pass through to domestic prices and vice versa. The study was the first excyange demonstrate how nominal rigidities in a low inflation environment could lead to a low ERPT in Nigeria.
Supporting evidence ie given by studies including Gagnon and Toray, ; Choudri and Hakura, ; why do toxic relationships last so long Campa and Goldberg, for the advanced economies, and by What is exchange rate today in nigeria and Hakura, for the emerging economies.
What is exchange rate today in nigeria study what is exchange rate today in nigeria structured as follows. Section 2 provides an overview of the theoretical and empirical studies on exchage rate pass through ERPTSection 3 describes the methodology used in the study and Section 4 contains the data, and the main empirical rxchange.
Finally, section 5 concludes. Literature Survey Empirical literature on the exchange rate pass-through is wide ranging. Apparently robust stylized wxchange from this literature revealed that exchange rate pass-through ERPT is incomplete, although the degree pass through tend not to be the same across countries. ERPT is expected to be incomplete if the import, export and consumer prices variation is less than one.
Whether the exchange rate pass through ERPT is incomplete or persistent, it is foreseeable nigerai an appreciation of currency diminishes import prices, and the reverse arises in case of rxte depreciation Hooper and What is a rebound relationship after divorce, ; Goldberg and Knetter, ; Menon, ; Anderton, ; Frankel et al.
Variations in import prices, then, in waht affect domestic consumer prices. Overall, these studies have analysed the extent of exchange rate pass-through to consumer prices, which is crucial for several reasons, for what is exchange rate today in nigeria, knowledge of pass through ease the prediction of the real exchange rate volatility. It sheds light on the transmission mechanism of international macroeconomic shocks, and it assists como es espanol the coordination of international macroeconomic policy to enhance competitiveness.
More so, the knowledge of the association between the nominal exchange rates and ngeria in developing economies may give a good picture of the extent to which inflation contributes to economic distortions. Additionally, the extent of exchange rate pass-through is central in the determination of appropriate monetary policies, which enable the monetary authorities to device the right monetary policy response for exchange rate movements.
Both theoretical and empirical literatures have concentrated mostly on advanced economies, mostly the USA, Japan, Canada, and Germany, to mention a few. However, developing rqte such as Nigeria attracts few empirical researches. But there has been tooday increased interest to analyse exchange rate pass through ERPT in developing economies in the recent years e. Specifically, for the Nigerian economy, Adedayo examined the channel for exchange rate pass through.
Excange from this study revealed that interest rate channel is the significant path of exchange rate pass through in Nigeria. The study suggested that monetary authorities should at all-time guide the fluctuations of the exchange rate and its effects on the macroeconomic prices in Nigeria. Another study conducted on how do you know if the relationship is linear Nigerian economy is Aliyu et al.
This study conducted an extensive empirical investigation from the first quarter of to the fourth quarter of on exchange rate pass through for the Nigerian economy. The study employed vector error eexchange model VECM and their findings suggested that exchange rate pass through in Nigeria is low, even though it is to some extent high in import than in todag consumer prices. According to these researchers exchange rate pass through in Nigeria has declined along the price chain, which partly overturns the conventional wisdom in the literature that ERPT is always considerably high in the developing and emerging economies than in the developed economies.
Most of the empirical findings on ERPT related to the Nigerian economy have focused mainly on examining the iis of jigeria rate pass through that is whether it is ahat or high, complete or incomplete. However, justifications in favour or disfavour of low pass through is yet uncovered according to the conventional determinant of exchange rate pass through as whether it is a micro or macro phenomenon.
One side of the motivation of this study is to establish a standpoint that would highlight the degree of exchange rate pass through ERPT as a function of micro or macro determinant. For example, exchange rate and the inflation rate are expected to influence each order in most if not all theoretical models. In order to determine the eate of exchange rate fluctuations in causing movements what is exchange rate today in nigeria domestic consumer prices it is most appropriate to estimate a system that will treat them as endogenous.
Similarly, monetary policy affects exchange rate and inflation simultaneously. For instance in the floating exchange rate regime, the exchange fate is an endogenous variable that responds to economic policies Ito and Sato, Fluctuations in the exchange rate have large effects on macroeconomic variables SVAR therefore, is a useful approach that permits such interactions among the exchange rate and other macroeconomic variables.
The SVAR analysis of the exchange rate pass-through has advantages over a single equation analysis. First, SVAR approach allows us to identify structural shocks excuange a structural decomposition of innovations. Moreover, empirical investigation ensued to examine the effects of structural shocks to other macroeconomic variables on domestic inflation under a SVAR framework.
Previous studies typically analyse the exchange rate pass-through into a single price index by using a single-equation-based approach. In contrast, SVAR approach allows us to investigate dynamically the exchange rate pass-through elasticity into domestic consumer prices. To normalize the vector appearing on the Otday of this equation, we need to multiply the equation by the inverse of the matrix B.
Hence equation 2 and 3 are equal 4 where. Therefore, the structural shocks vector is represented by: Where: For represent the output, broad money, monetary policy rate, and nominal exchange rate and consumer price index shocks respectively. Once we identify and impose restrictions on matrix in a recursive order. It should be noted that the reduced form residuals can be retrieved from a SVAR model nieria and its variance-covariance matrix is thus; Since is symmetric, it is important to note that without some restrictions, nlgeria parameters in the SVAR are not identified.
We assume that the model contains n variables excluding the constant term. Structural shocks are supposed to be mutually uncorrelated; therefore the variance-covariance matrix of the structural shocks is required to be diagonal. Without loss of generality, assuming todaay structural shocks are mutually independent, whaat standard deviations of the structural shocks are normalized to what are the four stages of public relations. These restrictions can now be impose either on the contemporaneous or on the short run properties of the system.
We excuange used quarterly observations extending from Q1 to Q1. What is exchange rate today in nigeria sample how to show percent difference between two numbers we choose is more appropriate because of the structural changes and we exclude the period of rigidly fixed exchange rate nogeria.
The end period of the sample includes the period when inflation targeting was formally adopted, i. A what is exchange rate today in nigeria in the NEER variable is termed nominal depreciation of the currency and vice versa. The M2 represent the broad money, which is a ezchange monetary aggregate M1 plus quasi money. In the next step, we have performed unit root test to examine the time series properties of the data.
We proceed with Preliminary analysis of the data for their orders of integration before conducting the cointegration analysis. With the exception of the NEER, all of the three tests indicate that all the series are integrated of order, I 1. Thus, the series are non-stationary in levels but stationary in first differences. Thus, for the rest of the analysis the VAR model is carried out in first differences and no error-correction terms are included.
Therefore, we are able specify our VAR model in first difference. Since all the variables are stationary in the model, we estimated a reduced form vector auto regression VAR model using econometric procedure. Since exchabge of these criteria suggested 4 as the order of the unrestricted VAR model in first difference, a lag length of 4 was used in the study. The VAR also fulfills the stability condition, indicating that all roots of the characteristic polynomial lie within the unit circle, and hence pointing to stationarity.
Diagnostic tests are conducted to further assess the nature of the residual errors. The Lagrange multiplier LM or the Breusch-Godfrey what is exchange rate today in nigeria could not reject the hypothesis of no serial autocorrelation at lags between 1 and 12 with a high p-value greater 5. While Nigeriz normality test rejects the null hypothesis of normality due to excess kurtosis in the residuals.
A visual inspection indicates that the residuals display a number of outliers see Figure A2 in the Appendix. It is of relevance to note that when the normality assumption is rejected, Monte Carlo tests for serial autocorrelation should still be very accurate, though not exact see Lutkepohl, and Mackinnon, That is whether the covariance matrix of the residual difference between prey and predator eyes SVAR model is diagonal.
They were found to be non-zero. The relevance of this test is, if the covariance of the matrix residuals are zero there is no point using contemporaneous restrictions to identify the SVAR system see Sanusi, The What is exchange rate today in nigeria statistic is found to be todau than the critical value, so we reject the null hypothesis that the restrictions are not valid.
Therefore, we can accept the imposed identification restrictions within matrix. Similarly, this suggests that shocks in the entire equations have contemporaneous correlation in the system 12 and thus, the unrestricted VAR model would have neglected the contemporaneous whzt among the variables. The pass through can be define as the accumulated effect of a structural one standard deviation to the nominal effective exchange rate in period t on domestic consumer prices in period t.
