Narrow Results

Various empirical methodologies have examined the relationship between exchange rate and household consumption expenditures. However, traditional methods fail to analyze the exchange rate effect on consumption across minor and major currency depreciation and appreciations. We attempt to extend the existing literature by examining the impact of minor and major currency appreciation and depreciation on household consumption expenditures in BRICST countries, including Brazil, Russia, India, China, South Africa and Turkey. We use an extended version of the nonlinear ARDL (NARDL) and multiple threshold nonlinear ARDL model called the multiple asymmetric ARDL (MATNARDL) model. Our estimates, based on the traditional NARDL model, indicate that the asymmetric effect is found in the context of India and China only. However, the MATNARDL estimates suggest that, in the long run, the asymmetric effect is found for all the sample countries except India whereas, in the short run, the asymmetric effect is found for all the sample countries except Turkey. Finally, this study recommends the policy implications based on the results obtained in this study.

This research has focused on examining the connection between uncertainties in economic policies and exchange rates. This research extends the literature to this field by analyzing the impact of small to large negative along with small to large positive variations in the economic policy uncertainty on the currency rates. For this purpose, this research uses the Granger causality in the quantile test and a newly constructed multiple asymmetric threshold nonlinear ARDL (MATNARDL) model. When a nonlinear ARDL model is utilized, our results confirmed the nonlinear impact in three nations only. In contrast, when the MATNARDL technique is utilized, these findings do confirm the nonlinear effect for all nations. Furthermore, when the Granger causality in the quantile test is applied, the impact differs over various quantiles. In general, the enhanced framework encourages us to analyze better how EPU affects the exchange rate in the emerging seven (E7) nations. The findings of our research may be useful for state banks to design policies to make interventions in the foreign currency market.
