J-curve relationship analyses can provide valuable insights to information systems (IS) researchers. This paper aims to discuss moderated mediation in IS research and the related emergence of J-curve relationships.

Building on an illustrative study in the field of IS, the author Lays out three steps to combine moderation and J-curve analyses, with the goal of more fully understanding the underlying moderated mediation relationships. The paper proposes a new segmentation delta method to test for J-curve emergence, as part of this framework.

The paper shows, in the context of this study, the complementarity of moderation and J-curve analyses.

Currently, IS researchers rarely conduct moderation and J-curve analyses in a complementary way, even though there are software tools, and related methods, which allow them to do so in a relatively straightforward way.

The analyses were conducted with the software WarpPLS, a widely used tool that allows for moderated mediation and J-curve analyses, in a way that is fully compatible with the set of steps presented in this paper.

In this paper we examine the validity of the J-curve hypothesis in four Southeast Asian economies (Indonesia, Malaysia, the Philippines and Thailand) over the 1980–2017 period.

We employ the linear autoregressive distributed lags (ARDL) model that captures the dynamic relationships between the variables and additionally use the nonlinear ARDL model that considers the asymmetric effects of the real exchange rate changes.

The estimated models were diagnostically sound, and the variables were found to be cointegrated. However, with the exception of Malaysia, the short- and long-run relationships did not attest to the presence of the J-curve effect. The trade flows were affected asymmetrically in Malaysia and the Philippines, suggesting the appropriateness of nonlinear ARDL in these countries.

The previous research tended to examine the effects of the real exchange rate changes on the agricultural trade balance and specifically the J-curve effect (deterioration of the trade balance followed by its improvement) in the developed economies and rarely in the developing ones. In this paper, we address this omission.

The purpose of this paper is to examine the J-Curve effect in Turkey at the industry level.

In order to find the long-run and short-run effects, 58 industries (by Standard International Trade Classification Rev.3) have been identified by using monthly data that covers the periods from January 1990 to December 2012. Present study employs bounds testing procedure, developed by Pesaran and Shin (1999) and Pesaran et al. (2001).

Although results indicate a positive satisfactory effect of real depreciation of lira in 13 industries, the J-Curve effect is detected in only 13 industries.

The present study is one of the first studies to analyze the J-Curve effect at the industry level on Turkey. In addition to being one of the first studies, it will be an invaluable addition to the J-Curve literature.

This paper investigates whether a J-curve can be detected in the time series data on China’s bilateral trade with the G-7 countries. It utilizes cointegration and causality tests to ascertain both the long-run relatedness, and the short-run dynamics, between the real exchange rate, national income, and the trade balance. There is some evidence that a real depreciation eventually improves the trade balance with some countries. But there is no indication of a negative short-run response which characterizes the J-curve.

Since the introduction of the concepts of the J‐ and S‐curves, many researchers have tried to verify their validity empirically. This paper aims to review the related papers and to offer direction for future research.

This is a review paper. As such, no method is employed here. Rather, the methodologies used by others to test the J‐ and S‐curves are explained and reviewed.

No new findings are offered since this is a review paper.

The J‐ and S‐curves show whether currency depreciation worsens the trade balance first before improving it. Since the majority of studies are country‐specific, policymakers could benefit by learning whether currency depreciation will be effective in improving the trade balance.

This is a literature review paper and its originality is in terms of collecting the literature together and presenting it in one single paper.

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.

The methodology is based on linear and nonlinear ARDL approach.

When nonlinearity is introduced into testing approach for the J-curve, more evidence is found in support of the J-curve.

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.

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.

Motivated by recent rapid exchange rate depreciations, shrank economic growth, high inflation, and persistent trade deficits, this study examines the trade balance (TB) in the face of the recent dynamics of the stated macroeconomic factors, which are also important determinants of the TB. The symmetric test of the J-curve phenomenon for the selected Sub-Saharan African (SSA) countries is revisited in this regard. The study uses panel data from 1970 to 2020 for ten of these countries for the longitudinal panel analysis with the TB as the dependent variable and the real exchange rate, foreign and domestic national incomes, and trade openness as the set of independent variables.

Because the underlying data set involves a heterogeneous panel of relatively short N and long T, the pooled mean group (PMG) and mean group (MG) heterogeneous panel models are employed based on the Hausman test for parameter consistency in heterogeneous panels.

The findings largely support the domestic income growth– TB worsening and the foreign income growth– TB improvement hypotheses. Trade openness is found to mostly augment the TB performance of the countries. The results also validated the J-curve effect for only 3/10 and 2/10 countries in the PMG and MG models, respectively. The divergence for most of the countries is attributed to possible import compression and institutional structure of SSA countries.

Given the favorable effects of trade openness on the TB performance of SSA countries, it is recommended that SSA countries place much emphasis on import-substitution industrialization and value addition to their natural resources as well as investment-driven growth policies to improve the competitiveness of their exports and reverse the chronic deficits in their TBs.

This paper is unique for invoking heterogeneous panel models to analyze the TB in light of recent dynamics of its determinants, as well as providing an update on the symmetric test of the J-curve phenomenon for the selected SSA countries.

The purpose of this paper is to use disaggregated data on US‐UK trade to investigate the effects of exchange rate depreciation on trade in services both in the short‐ and long‐run.

The paper focuses on the three traditional categories of internationally traded services – travel, passenger fares and other transportation services – and employs the “bounds” testing procedure advanced by Pesaran, Shin and Smith to investigate the J‐curve effect.

The results reveal that the real exchange rate has a statistically significant effect on trade in services in at least one of the time periods. The results also provide some support for the J‐curve effect.

Empirical evidence on the J‐curve provides policymakers with valuable information about the effects of currency depreciation on the trade balance.

To the best of the author's knowledge this is the first paper to investigate the J‐curve effect using data on trade in services.

This paper investigates the relationship between the sustainable finance disclosure regulation (SFDR) and the performance of unlisted real estate funds.

While existing literature has primarily focused on the impact of voluntary sustainability disclosure, such as certifications or reporting standards, this study addresses a significant research gap by constructing and analyzing the financial J-Curve of 40 funds under the SFDR. The authors employ a panel regression analysis to examine the effects of different SFDR categories on fund performance.

The findings reveal that funds categorized under Article 8 of the SFDR do not exhibit significantly poorer performance compared to funds categorized under Article 6 during the initial phase after launch. On average, Article 8 funds even demonstrate positive returns earlier than their peers. However, the panel regression analysis suggests that Article 8 funds slightly underperform when compared to Article 6 funds over time.

While investors may not anticipate lower initial returns when opting for higher SFDR categories, they should nevertheless be aware of the limitations inherent in the existing SFDR labeling system within the unlisted real estate sector.

To the best of our knowledge, this study represents the first quantitative examination of unlisted real estate fund performance under the SFDR. By providing unique insights into the J-Curves of funds, our research contributes to the existing body of knowledge on the impact of sustainability regulations in the financial sector.

The purpose of this paper is to study empirically the dynamics of Turkish bilateral trade between Turkey and her nine trading partners, in addition to aggregate trade balance data.

The paper employs cointegration, generalized impulse response analysis, and stability tests.

The empirical results suggest non‐existence of the J‐curve effect at disaggregate and aggregate levels. However, Marshall‐Lerner condition holds for the aggregate data along with some of the trading partners. With regard to the stability of trade balance equations, the findings are mixed.

Conclusions drawn from this study could be useful for the policy makers of governments and practitioners in international trade organizations.

This paper extends the existing literature by providing initial evidence at disaggregate data in the case of Turkey. Moreover, for the first time disaggregate and aggregate data are utilized in the same analysis.
