This paper investigates the ability of gold to hedge worldwide risks from the perspective of global economic policy uncertainty (GEPU). By applying the full- and sub-sample rolling-window bootstrap causality tests to analyze the dynamic interaction between GEPU and gold price (GP). It can be observed that gold can effectively hedge risks of GEPU during the Asian financial crisis, dot-com bubble and global economic crisis, but this result does not hold in non-crisis period. GEPU manifests two-way impacts on the GP in a few periods, this relationship between GEPU and GP being consistent with the hypothesis in the general equilibrium model, which states that changes in GEPU lead to the fluctuations of GP. In turn, GP has both positive and negative impacts on GEPU. In the current complex economic situation, governments and investors can consider gold to hedge risks of GEPU, especially during the economic crises.

The objective of this study is to provide evidence for the existence of threshold effects in trade openness, which affects the female labour force participation rate (FLFPR) in Asian countries. The authors employ the proportion of export, import and total trade volume to gross domestic product to denote export and import dependency and trade openness, respectively. The panel threshold regression results indicate that there exists an optimal value in the correlation between trade openness and FLFPR below which an increase in trade openness will enhance the FLFPR; an adverse relationship exists when trade openness exceeds the threshold value. This relationship is attributed to the trade-off between the cost reduction effect and the technology channel. Furthermore, the authors further categorise trade openness into export and import dependency. The findings reveal that export dependency also has a single threshold effect on FLFPR, while import dependency exerts a negative effect on FLFPR regardless of threshold effect. Therefore, the government could promote female participation in the labour force by regulating the export policy.

This paper probes the interrelationship between Bitcoin price (BP) and the U.S. partisan conflict (PC) by performing the bootstrap full- and sub-sample Granger causality tests. The positive influence from PC to BP reveals that Bitcoin can be considered as a tool to avoid the uncertainty caused by the rise in PC. However, this view cannot be supported by the negative impact, the major reason is that the burst of bubble undermines the hedging ability of Bitcoin. The above results are inconsistent with the intertemporal capital asset pricing model (ICAPM), underlining that high PC may drive BP to rise, in order to compensate for the losses and costs from factionalism. Conversely, BP has a negative impact on PC, suggesting that the U.S. political situation can be reflected by the Bitcoin market. Under the circumstance of the fiercer factionalism in the U.S., this investigation can benefit investors and related authorities. First published online 04 February 2021
