Exchange Rate Reform and the Dynamics of Net-Export in Nigeria (Published)

In this paper, the short- and long-term empirical relationship between net-export and exchange rate variation in Nigeria was estimated using error correction model (ECM) and Fully-Modified least squares (FM-OLS) for the period, 1986-2017. The impacts of degree of openness and tariff on net-export were equally examined over the study period. Prior to the actual estimation of the model, the series were subjected to unit root test using Phillips-Perron method and the results that they are all first difference stationary. Additionally, the cointegration test result revealed that the linear combinations of the of the nonstationary series leads to long run relationship amongst them. The parsimonious ECM shows that the variables jointly exert significant impact on net-export in the short run. It was also observed from the error correction coefficient that any short run disequilibrium in the system can be reconciled at 53.47 percent to achieve long run equilibrium position. The estimated cointegrating regression model shows that nominal effective exchange rate exerts significant positive impact on net-export in the long run. Overall, the F-test result for joint significant of the series reveal that the all the variables are collectively important in influencing changes in net-export. On the basis of the findings, it is recommended that policy makers should ensure that exchange rate policy prevalent in the Nigeria economy is tailored towards making exports more competitive in the international market in order to boost net-export growth and maintain stability in the domestic economy.

Fluctuation Rate Analysis of Rupiah Exchange in the Indonesian Open Economy (Published)

This research aimed to analyze the long-term balance between KURS (Rate of Exchange), inflation (INF), Foreign Direct Investment (FDI), interest rate of Bank Indonesia (SBI), and the degree of openness of Economics (DKE) An open economy Indonesia using time series data period 1998: 1-2016: 4. Models Autoregressive Distributed Lag (ARDL) was used to observe the effect of these variables. The results show that there is a balance of long-term fluctuations in the exchange Rate against the US dollar which is influenced by the variable inflation and SBI are negatively correlated with the exchange rate. While the FDI variable and the degree of economic openness is positively correlated with the exchange rate. The degree of openness of the economy, inflation, FDI leads to fluctuations on the exchange rate. In the long term, SBI gives a significant effect on the exchange rate. Among the exchange rate with the degree of economic openness has a positive and significant impact. This means that increasing the degree of economic openness, it will result in the appreciated (US dollar depreciated). Economic openness leads to significant fluctuations in exchange rates in the short term and long term.
