Comprehensive Study

A country is said to live within its international budget constraint if its exports and imports are cointegrated. Previous studies that tried to verify the cointegration between exports and imports used linear models and supported the theory in almost 50% of countries. In this paper, when we use the nonlinear ARDL approach and asymmetry cointegration method, we support the long-run link between imports and exports in 94 out of 100 countries in our sample. This study is not only the most comprehensive study in the literature, but it is also the first to show that, indeed, trade flows adjust in a nonlinear fashion.

The study asseses the influence of  migrant remittances on financial development over the period of 1976-2018 in Pakistan. This study has applied the linear autoregressive distributive lag (ARDL) model and nonlinear autoregressie distributed lag (NARDL) model to check the symmetric and asymmetric effect of remittances. Results of the ARDL and NARDL bound test confirm remittances, FDI, real GDP and inflation significantly contributing to financial development. The outcomes of ARDL and NARDL have also confirmed the significant positive effect of  migrant remittances on financial development in long-run. The asymmetric ARDL  results show the existence of remittances nonlinear effect  on financial development. Specifically, the study found remittances decrease have a significant impact while remittances increase have no any significant effect on financial development. Based on findings, this study recommends the plan for the policymakers of recipient countries, especially Pakistan, could harvest the potential gain of migrant remittances though positive asymmetric association with financial sector development.

Abstract The purpose of this paper is to investigate the links between renewable energy (RE), non-renewable energy (NRE), capital, labour and economic growth, using the Non-linear Auto Regressive Distributive Lag (NARDL) model in Malaysia for the period of 1980–2018. The results of NARDL confirm the asymmetric effect of RE and NRE consumption on the economic growth in the long run as well as short run in Malaysia. The findings also show that in the long and short-run, positive shocks of NRE are greater than the positive shocks of RE. It indicates that Malaysia's economic growth is highly dependent on NRE which is not a good indication as NRE consumption increases carbon dioxide (CO2) emission in the country. Moreover, the empirical results of this study demonstrated that RE consumption reduction accelerates economic growth whereas NRE consumption reduction decreases economic growth. It can have claimed that in Malaysia RE is still more expensive than NRE. In conclusion, this study offered a variety of measures to develop RE to reduce the dependency on NRE consumption.

This paper investigates possible asymmetric influences of the exchange rate on cross-border freight flows between the U.S.A. and Canada. Linear and nonlinear autoregressive distributed lag models are used to test for the existence of long-run asymmetric effects of 1) currency appreciation and depreciation and 2) exchange rate volatility changes on trade flows by truck, rail, air, vessel, and pipeline. This paper provides evidence that both currency value and exchange rate volatility affect the U.S.–Canada freight flows in an asymmetric manner. The long-run results of the nonlinear models show that exchange rate is found to be significantly associated with the bilateral trade flows between the U.S.A. and Canada. Exchange rate volatility tends to be significantly associated with trade flows in the nonlinear models, while its effects are insignificant in most cases in the linear models. These findings suggest that the conventional linear specification may mislead the asymmetric effects of exchange rate uncertainty on cross-border freight flows. It is also found that exchange rate sensitivities of U.S.–Canada trade flows by transport mode can differ significantly from those of aggregate trade flows. The information derived from disaggregate trade data can be useful for traders and shippers to develop a long-term strategic plan for infrastructure investment and service expansion.

China is the largest trading partner of Pakistan. Therefore, it is very important to consider the trade flows between Pakistan and China and their response to rupee–yuan volatility. Previous research assumed that response of trade flows to measure of volatility is symmetric. In this study, our basic objective is to check whether the trade flows respond to volatility in a symmetric or asymmetric manner. Annual data over the period 1980–2018 for 14 Pakistani industries exporting to and 34 industries importing from China are analyzed. We find short-run asymmetric effects of exchange rate volatility in almost all industries that last into long-run asymmetric effects in 40–50 per cent of industries. Non-linear models yielded more significant effects of volatility than the traditional linear models.

Purpose – Previous research that investigated the effects of currency depreciation on the trade balance assumed that the adjustment of all variables in a given model is in linear fashion. The authors wonder if introduction of nonlinearity in the adjustment of some variables such as the exchange rate can shed additional light on evidence of the J-curve. The new approach also allows to test whether exchange rate changes have symmetric or asymmetric effects on the trade balance. Estimates of a trade balance model for Canada, China, Japan, and the USA reveal that the effects are indeed asymmetric. The paper aims to discuss these issues. Design/methodology/approach – The methodology is based on linear and nonlinear ARDL approach. Findings – When nonlinearity is introduced into testing approach for the J-curve, more evidence is found in support of the J-curve. Research limitations/implications – The models are estimated using aggregate trade flows of each country with the rest of the world, hence they suffer from aggregation bias. Using trade flows at bilateral level and at commodity level are highly recommended for future research. Originality/value – This is the first paper that applies nonlinear ARDL approach to test the short-run and long-run effects of currency depreciation on the trade balance.

Exchange Rate Changes

Previous studies that tested the short-run and long-run effects of exchange rate changes on trade balances assumed that the effects are symmetric. The more recent research direction has now changed to investigating the possibility of asymmetric effects. In this paper, we assess the short-run and long-run effects of exchange rate changes on the bilateral trade balances of Singapore with her 11 partners. By applying the nonlinear ARDL approach, which separates appreciations from depreciations, we find that exchange rate changes have short-run asymmetric effects in most models. The short-run effects, however, lasted into the long run in a few models. In the long run, while depreciation improves Singapore’s trade balance with the U.S., it hurts it with Malaysia and China. These three partners account for almost 50 % of Singapore’s trade.

Incoming foreign direct investments (FDI) may enhance the productivity level of the host country by bringing new advanced technologies. On the other hand, the nexus of FDI and productivity, rather than being linear, might be nonlinear because the effect of increases and decreases in FDI on productivity may not be symmetric. In this sense, this study investigates the asymmetric relationship between FDI and productivity in Turkey by using two different productivity indicators (i.e., PROD1 and PROD2) and employing a Nonlinear ARDL approach. Our hypothesis claims there is an asymmetric association between FDI and productivity in the long run in Turkey. Nonlinear cointegration test findings indicate that selected variables are cointegrated. Hence, they move together in the long run. Our study uses aggregated data at the macro level to analyze the long-term asymmetric relationship between foreign direct investment and labor productivity in Turkey using the NARDL estimation technique. Concerning the estimation results, a long-run nonlinear relationship between incoming FDI and labor productivity was detected, and this finding remained valid across two models constructed by using two distinct labor productivity indicators. As a whole, our results are consistent with the ones found in the literature. Besides, for the first time in the literature, this study addresses the long-run asymmetric nexus between FDI and labor productivity by using macro-level data specific to Turkey and makes various policy recommendations.

Purpose The purpose of this paper is to show that in some industries the linear model may not reveal any significance link between exchange rate volatility and trade flows but once nonlinear adjustment of exchange rate volatility is introduced, the nonlinear model reveals significant link. Design/methodology/approach This paper uses the linear ARDL approach of Pesaran et al. (2001) and the nonlinear ARDL approach of Shin et al. (2014) to assess asymmetric effects of exchange rate volatility on trade flows between Germany and Turkey. Findings This paper consider the experiences of 75 2-digit industries that trade between Turkey and Germany. When the study assumed the effects of volatility to be symmetric, the study found short-run effects in 31 (30) Turkish (German) exporting industries that lasted into the long run in only 10 (13) Turkish (German) exporting industries. However, when the study assumed asymmetric effects and relied upon a nonlinear model, the study found short-run asymmetric effects of volatility on exports of 55 (56) Turkish (German) industries. Short-run asymmetric effects lasted into long-run asymmetric effects in 10 (25) Turkish (German) exporting industries. All in all, we found that almost 25% of trade is hurt by exchange rate volatility. Originality/value This is the first paper that assesses the possibility of asymmetric effects of exchange rate volatility on German–Turkish commodity trade.

Nonlinear Ardl Model

Very recently, the link between exchange rate volatility and trade flows has entered into a new direction in which researchers assess the possibility of asymmetric response of trade flows to a measure of exchange rate uncertainty. We add to this literature by estimating a linear and a nonlinear ARDL model to learn about the experiences of Asian countries, i.e., Pakistan, Japan, China, Korea, Singapore, Malaysia, the Philippines, and India. Like other studies in the literature, nonlinear models yielded relatively more significant results. In some cases, while the linear models showed no significant effects of exchange rate volatility on trade flows, the nonlinear models revealed significant effects. In some other cases, the opposite was true.
