This study examines the indirect hedging strategy and its price ccndition against exchange risk for the export firms which can not directly hedge due to non-existence of appropriate futures market for the export market currency. The export firms would manipulate their mark-up rate as real hedging against exchange risk in the incomplete export market. Real options tend to reduce the uncertainty of an export profit curve in nonlinear manner and thus, substitute for the financial hedging. As a result, the optimal hedging strategy for the firms exporting to the incomplete market is an under hedge combining short futures and long put. The long put is a substitute with short futures and required to cover the nonlinear risk of export profit derived by real options. Indirect hedging would increase the expected profit by reducing risk, while a sufficient and necessary condition for the optimal indirect hedging depends on exchange volatility and a magnitude of put premium relative to an expected excercise loss.

This study aims to conduct an empirical investigation to assess the hedge, diversifier and safe-haven properties of different environmental, social and governance (ESG) assets (i.e. green bonds and ESG equity index) vis-à-vis conventional investments (namely, equity index, gold and commodities).

The authors examine the sample period 2007–2021 using the bivariate cross-quantilogram (CQG) analysis and a dynamic conditional correlation (DCC) multivariate generalized autoregressive conditional heteroskedasticity (GARCH) experiment with several extensions.

The evidence shows that the analyzed ESG investments exhibit mainly diversifying features depending on the asset class taken as a reference, with some potential hedging/safe-haven qualities (for the green bond) in peculiar timespans. Therefore, the results suggest that investors might consider sustainable investing as a new measure of risk reduction, which has interesting implications for both portfolio allocation and policy design.

To the best of the authors’ knowledge, this study is the first that empirically investigates at once the dependence between different ESG investments (i.e. equity and green bond) with different conventional investments such as gold, equity and commodity market indices over a large sample period (2007–2021). Well-suited methodologies like the bivariate CQG and the DCC multivariate GARCH are used to capture the spillover effect and the hedging/diversifying nature, even in temporary contexts. Finally, a global perspective is used.

In order to mitigate the effects of climate change, the UK government has set a target of achieving net zero greenhouse gas (GHG) emissions by 2050. Agricultural GHG emissions in 2017 were 45.6 million tonnes of carbon dioxide equivalent (CO₂e; 10% of UK total GHG emissions). Farmland hedgerows are a carbon sink, storing carbon in the vegetation and soils beneath them, and thus increasing hedgerow length by 40% has been proposed in the UK to help meet net zero targets. However, the full impact of this expansion on farm biodiversity is yet to be evaluated in a net zero context. This paper critically synthesises the literature on the biodiversity implications of hedgerow planting and management on arable farms in the UK as a rapid review with policy recommendations. Eight peer-reviewed articles were reviewed, with the overall scientific evidence suggesting a positive influence of hedgerow management on farmland biodiversity, particularly coppicing and hedgelaying, although other boundary features, e.g. field margins and green lanes, may be additive to net zero hedgerow policy as they often supported higher abundances and richness of species. Only one paper found hedgerow age effects on biodiversity, with no significant effects found. Key policy implications are that further research is required, particularly on the effect of hedgerow age on biodiversity, as well as mammalian and avian responses to hedgerow planting and management, in order to fully evaluate hedgerow expansion impacts on biodiversity.

This article empirically tests the time-correlation of implied information reflecting the return dynamics of KOSPI 200 markets in the view of the decision making and market efficiency. Because option prices are not perfectly correlated with each other and with the underlying asset, the information contents of the option are different from those of the underlying market price. And, under the non-complete of the market and the limited arbitrage, the information implied in option (underlying) market price may be more useful in the option (underlying) market than in the underlying (option) market.

The estimation results show that the time-correlation of incremental information are existed in performance of out-of-sample pricing and delta hedging conditioned on MR, a result which is not suggestive of the informational efficiency of the KOSPI 200 market. But, the decision marking using the systematic pattern may not be useful due to the option pricing models that allows moments of higher order than two reflecting the source of which the risk-neutrality assumption is strongly rejected by the data.

Drawing upon underinvestment theory and clientele effect hypothesis, this paper aims to examine the effects of foreign currency (forex) exposure and Shari’ah-compliant status on firms’ financial hedging strategy.

Based on data of 250 nonfinancial firms listed on Bursa Malaysia from 2010 to 2018 (2,250 firm-year observations), the authors test the impact of forex exposure based on a vector of foreign-denominated cash flows (FCF) indicators and firms’ Sharīʿah-compliant status on two proxies of financial hedging decisions, namely, the ratio of the notional value of currency derivatives to total assets and a binomial measure of hedging status. The hedging decision models are estimated using panel logistic regression and system generalized method of moments.

The results indicate significant positive effects of the forex exposure indicators on firms’ propensity to hedge. However, the impact of forex exposure is most prevalent via total FCF. The results also reveal significant positive effects of Sharīʿah-compliant status on firms’ propensity to hedge but its negative impacts on the value of currency derivatives they use. The results suggest that Sharīʿah-compliant firms refrain from engaging in currency derivatives to avoid riba’ and subsequently subdue the clientele effect. However, when the forex exposure reaches higher levels, engagement in currency derivatives becomes a matter of tentative necessity (dharurat).

This study relies exclusively on the disclosure of foreign currency risk and management data in the annual reports of listed companies. Consequently, this limits the sample size to only those nonfinancial listed companies with complete data for the study period. Also, since none of the companies reports using Sharīʿah-compliant derivatives, the authors thus assume that they use derivative instruments that tolerate “riba.”

Given the significance of forex exposure on hedging decisions, the accounting profession must strictly adopt FRS 7 and FRS 139 for all listed firms to avoid market scrutiny and sustain their clientele. The results also call for the Islamic market regulators to include mandatory disclosure of conventional currency derivatives in screening firms for clearly prohibited activities to help enhance the credibility of its Islamic financial market.

Due to difficulty accessing relevant cash flow data, the study is among the few studies that measure forex exposure using FCF and test more proxy indicators. This study is perhaps the first to examine the Shari’ah perspective on currency derivatives in corporate forex risk management.

The purpose of this paper is to unveil the main changes in the UAE’s policy towards Iran since its foundation in 1971. The UAE favored strategic hedging, extending its commercial and diplomatic relations with Iran, in addition to developing its military capabilities and maintaining military/security alliances with Saudi Arabia and the USA. However, the UAE started to reorient its policy towards Iran by adopting some sort of balancing strategy in the aftermath of the Arab Spring of 2011. This paper examines how and why the UAE had to change course and explores whether it would revert back to strategic hedging with Iran.

The study will be carried out based on a theoretical framework drawn from strategic hedging theory, a new structural theory in international relations, to examine the shifts in UAE policy towards Iran. Previous literature suggests that small states prefer hedging over balancing or bandwagoning. The authors also undertake a descriptive analysis and deploy a longitudinal within-case method to investigate changes in UAE policy towards Iran and identify the causal mechanisms behind these changes. That method allows investigating the impact of a particular event on a case by comparing the same case before and after that event occurred.

The main finding of this study is that the UAE hedging strategy towards Iran allowed maximizing the political and economic returns from the cooperation with Iran and mitigating the long-range national security risks without breaking up the consistent and beneficial ties with other regional and global powers. Hedging achieved the desired outcome, which is preventing direct military confrontation with Iran. Hard balancing, adopted by Abu Dhabi after the 2011 Arab Spring, has proved to have some negative effects, most importantly provoking Tehran. Some recent indicators suggest, though that the UAE may revert back to its long-established hedging policy towards Iran.

Strategic hedging is a new structural theory in international relation, although hedging behavior in states’ foreign policies is far from new. It is new enough, thus, not have been researched sufficiently, strategic hedging still needs theorizing and comparison. This paper highlights the importance of strategic hedging as the most appropriate strategy for small states. It provides an important contribution to the application of the theory to the case of UAE policy towards Iran. The paper also assesses the conventional wisdom that small states prefer hedging over balancing in the light of the changes in the UAE foreign policy since 2011.

This study investigates whether the disclosure of derivatives is value relevant in emerging markets and evaluates the effects of the 2008/2009 global financial crisis on the value relevance of derivative disclosures.

Panel regression models using sub-samples and a crisis interaction term were applied to a sample of the 200 largest non-financial firms by market capitalization listed on the Johannesburg Stock Exchange (JSE) from 2005 to 2017 to assess the consequences of the financial crisis.

The results suggest that the disclosure of derivatives is value relevant in the hitherto understudied context of emerging markets. The 2008/2009 financial crisis had a significant impact on derivatives use and the value relevance of derivatives disclosure by JSE-listed companies.

Companies should reconsider both how they employ derivatives as part of their risk management practices and how they communicate derivatives use to stakeholders in the financial statements. The findings facilitate a comparative analysis across various market contexts by researchers and assist investors in better decision-making. The findings can influence regulatory practices and can help standard setters to review disclosure requirements.

The benefits of corporate hedging were studied from an emerging market perspective, using an original dataset and approach to investigate the effects of international financial volatility on emerging markets. The authors tested whether companies are valued differently, based on their disclosure of the use of derivatives in the financial statements, and the effect of the financial crisis on the value relevance derivatives disclosures.
