This study aims to investigate the causal relationships between the economic policy uncertainty (EPU) index and the US stock indices the S&P 500, Dow Jones and Nasdaq 100 over the period of 1985M10–2016M12. To this aim, it is applied both linear causality and the nonlinear rolling window causality tests. The long-run analyses are also applied to reveal the elasticities of the US stock indices. The empirical findings indicate that both the linear and the nonlinear approaches support the evidence of causal relationships from the US EPU index to all the US stock indices. Additionally, it is also found some evidences of causal relationships from these three US stock indices to the US EPU index especially between 2008–2013 in the latest financial crisis and in the late 2016. The results indicate that the Nasdaq 100 index is mostly affected from the US EPU index both in the short and long-runs.

The purpose of this study is to investigate the effects of the COVID-19 pandemic on economic policy uncertainty in the US and the UK. The impact of the increase in COVID-19 cases and deaths in the country and the increase in the number of cases and deaths outside the country may vary. To examine this, the study employs the bootstrap ARDL cointegration approach from March 8, 2020 to May 24, 2020. According to the bootstrap ARDL results, a long-run equilibrium relationship is confirmed for five out of the ten models. The long-term coefficients obtained from the ARDL models suggest that an increase in COVID-19 cases and deaths outside of the UK and the US has a significant effect on economic policy uncertainty. The US is more affected by the increase in the number of COVID-19 cases. The UK, on the other hand, is more negatively affected by the increase in the number of COVID-19 deaths outside the country than the increase in the number of cases. Moreover, another significant finding from the study demonstrates that COVID-19 is a factor of great uncertainty for both countries in the short-term.

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.

Abstract The purpose of this study is to investigate the effects of the COVID-19 pandemic on economic policy uncertainty in the US and the UK. The impact of the increase in COVID-19 cases and deaths in the country, and the increase in the number of cases and deaths outside the country may vary. To examine this, the study employs bootstrap ARDL cointegration approach from March 8, 2020 to May 24, 2020. According to the bootstrap ARDL results, a long-run equilibrium relationship is confirmed for five out of the 10 models. The long-term coefficients obtained from the ARDL models suggest that an increase in COVID-19 cases and deaths outside of the UK and the US has a significant effect on economic policy uncertainty. The US is more affected by the increase in the number of COVID-19 cases. The UK, on the other hand, is more negatively affected by the increase in the number of COVID-19 deaths outside the country than the increase in the number of cases. Moreover, another important finding from the study demonstrates that COVID-19 is a factor of great uncertainty for both countries in the short-term.

The Impact

This study uses threshold cointegration technique to ascertain the relationship between United States (US) economic policy uncertainty (EPU) and monetary policy rate (MPR) of each of the four African countries, namely Egypt, Ghana, Namibia and South Africa using monthly data from March 1998 to April 2020. The impact of US EPU on MPR of each country is assessed by examining the linear cointegration, asymmetric cointegration and causal relationships in the frequency domain between the US EPU and MPR of each African country. The findings provide evidence of long-run threshold cointegration and the adjustment mechanisms towards long-run equilibrium are asymmetric in the short run for the MPR models for Ghana, Namibia and South Africa in the M-TAR specification except for Egypt’s MPR model which does not provide evidence of asymmetric adjustment towards the equilibrium position. The bivariate analysis performed in the spectral frequency domain suggests unidirectional causality between US EPU and MPR of each country and that, the US EPU influences the MPR of each country in the long run. The findings provide important guidelines to monetary policy reviewers to take policy stance that would stimulate economic growth amid US policy uncertainties.

Following generalized variance decomposition, we identify the transmission structure of financial shock among ten sectors in China. Then, we examine whether economic policy uncertainty (EPU) affects it through GARCH-MIDAS regression. We find that consumer discretionary, industrials, and materials sectors are systemically important industries during the sample period. Further research of dynamic analysis shows that each sector acts in a time-varying role in this structure. The results of the GARCH-MIDAS regression indicate that none of the selected EPU indexes has a significant long-term impact on the total volatility spillover of the inter-sector stock market in China. However, the EPUs do affect some sectors’ spillover indexes in the long run, and they are significantly heterogeneous. This paper can provide regulatory suggestions for policymakers and reasonable asset allocation and risk avoidance methods for investors.

Positive Effect

This article models the endogenously interrelated relationship between global economic policy uncertainty (EPU), world industrial production (WIP), and the demand for US tourism net export (TNX) expenditures. To do so, we apply an identified structural vector autoregression model over monthly data spanning from January 1999 to October 2020. Our findings reveal that a positive shock in WIP has a significant positive effect on demand for TNXs. In contrast, unanticipated increases in price and EPU have a statistically significant negative effect on TNXs. Our results show that, in the long run, a one standard deviation shock in global EPU explains about 26.05% of the variations in tourism net service exports.
