Insurance and economic policy uncertainty

Just as the world has witnessed the increased importance of the insurance sector over the past few decades, it has also witnessed a sharp rise in risks and uncertainties. Surprisingly, studies analyzing the relationship between economic policy uncertainty and the insurance sector are almost non-existent. Another major limitation of insurance literature is the choice of methodology. Most studies on the insurance sector do not take into consideration issues of heterogeneity and cross-sectional dependence, and are therefore subject to errors. To address the identified gaps, this research investigates the impact of economic policy uncertainty on insurance premiums in a panel of 15 countries over the period 1998–2016 by employing heterogeneous panel estimation techniques with cross-sectional dependence. The Durbin-Hausman cointegration tests of Westerlund (2008) confirm that a long-run relationship exists between the variables. Findings from the error correction based panel estimations show that the insurance sector is not immune to the effects of economic policy uncertainty. Economic policy uncertainty raises insurance premiums both in the short and long run, although the long-run impact is greater than the short-run impact. In addition, economic policy uncertainty exerts a bigger influence on non-life insurance premium than on life insurance premium, indicating that the economic risks covered by non-life insurance are more sensitive to uncertainty than the mortality and longevity risks covered by life insurance. Our findings further show that national income, education, population, financial development and institutional quality all raise insurance premiums, while inflation lowers insurance premiums.     

Oil prices and economic policy uncertainty: Evidence from global,oil importers,and exporters’ perspective

Containing various information, economic policy uncertainty reflects significant rises and declines when facing shocks like financial crisis, oil-price change, and other specific economic or policy events. This paper empirically studies the interaction between oil prices and the newly formulated economic policy uncertainty indices using a time-varying parameter vector autoregression framework. Generally, the results of this study suggest that economic policy uncertainty reveals fluctuating responses to oil price shocks, while the oil price has a negative response to the uncertainty. The findings also reveal that the economic policy uncertainty indices for oil-importers and oil-exporters respond to oil price shocks differently. The oil price shock has a larger fluctuation to the economic policy uncertainty of oil-exporters than that of importers. Moreover, for the oil-exporters, the negative response to the oil price shock is greater than that of the oil-importing countries. This paper also discusses the impact of asymmetric shocks of oil price on economic policy uncertainty. In particular, after two financial crises, positive shocks decrease the uncertainty and vice versa. These findings are robustly verified.     

Wholesale funding and bank stability: The impact of economic policy uncertainty

The primary aim of this paper is to examine the conditioning effects of economic policy uncertainty on the relationship between wholesale funding and bank stability. Based on a sample of 1829 commercial banks in 27 countries over the period 2005–2020, we provide evidence of a nonlinear relationship between wholesale funding and bank stability. Specifically, a small share of nondeposit funding to total deposit and short-term funding (below 22.3%) offers some risk reduction, but a substantial mixing of nondeposit and deposit funding increases bank fragility. Moreover, the adverse effects of excessive wholesale funding on bank stability are strengthened during periods of high policy uncertainty. Nevertheless, banks in advanced countries, large banks, and high-quality banks with better asset quality are less affected by the detrimental impact of excessive wholesale funding on bank stability when during periods of increased policy uncertainty.     

How does economic policy uncertainty affect the bitcoin market?

This paper examines how economic policy uncertainty (EPU) impacts the Bitcoin (BTC) markets denominated in local currencies. We take BTC against British Pound (GBP) and the United States dollar (USD) as examples and construct the value-weighted BTC/GBP and BTC/USD composite indices. Our results show that the returns around the highest EPU days are significantly greater than those around the lowest EPU days. Further, the United States (US) EPU increases the volatility and trading volume of BTC after EPU spike days, whereas the United Kingdom (UK) EPU does not show such trends. Moreover, we observe a spillover effect for the US EPU to the UK BTC market. We further construct the dynamic conditional correlation (DCC)-GARCH model to test the dynamic correlation between EPU and BTC. Our results show that the effect of the US EPU on BTC/USD is greater than the effect of the UK EPU on BTC/GBP. Our empirical findings may provide insights for regulators to intervene in speculations in cryptocurrency markets effectively.     

When to go abroad: economic policy uncertainty and Chinese firms’ overseas investment

We study how economic policy uncertainty (EPU) influences firms’ overseas investments for Chinese listed companies. We find a significant negative relationship between EPU and firms’ overseas investments after controlling for firm characteristics and macroeconomic variables. Chinese firms seem to reduce their overseas investments on fixed income securities when facing domestic policy uncertainty. The negative relationship is pronounced for financially constrained firms, firms relying on government subsidies and with low overseas revenues, and SOEs. Firms operating in high marketisation regions can mitigate the negative effect of EPU on firms’ overseas investments. Our results remain significant when considering endogeneity problems.     

Does economic policy uncertainty affect cryptocurrency markets? Evidence from Twitter-based uncertainty measures

Using daily data from August 9, 2015, to July 7, 2020, this study examines the effects of economic policy uncertainty (EPU) on the returns of four cryptocurrencies: Bitcoin, Ethereum, Litecoin, and Ripple. To this end, two new measures of EPU (Twitter-based economic uncertainty and Twitter-based market uncertainty) are considered. A Granger causality test using the recursive evolving window approach shows a significant causality between the Twitter-based EPU measures and the BTC/USD exchange rate from October 2016 to July 2017. Moreover, a significant causality was noted from the EPU measures to the ETH/USD exchange rate from June 2019 to February 2020 and from the EPU measures to the XRP/USD exchange rate from January 2020 to February 2020. The Twitter-based EPU measures primarily positively affect the returns of the related cryptocurrencies during these periods. These results are robust to different measures of Twitter-based EPU and different econometric techniques. Potential implications, including the COVID-19 era, are also discussed.     

A comparative analysis of cryptocurrency returns and economic policy uncertainty pre- and post-Covid-19

This study analyzes the impact of economic policy uncertainty (EPU) on cryptocurrency returns for a sample of 100 highly capitalized cryptocurrencies from January 2016 to May 2021. The results of the panel data analysis and quantile regression show that increases in global EPU have a positive impact on cryptocurrency returns for lower cryptocurrency returns quantiles and an adverse impact for upper quantiles. In line with the existing literature, the Covid-19 pandemic resulted in higher returns for cryptocurrencies. Inclusion of a Covid-19 dummy in the models strengthened the impact of EPU on cryptocurrency returns. Furthermore, the relationship between the change in EPU and cryptocurrency returns was direct in the pre-Covid-19 period but inverse in the post-Covid-19 period. These results imply that cryptocurrencies act more like traditional financial assets in the post-Covid-19 era.     

Economic policy uncertainty and corporate cash policy: International evidence

I investigate the influences of economic policy uncertainty on corporate cash policy. The findings show that there is a positive association between economic policy uncertainty and cash holdings, as well as the propensity to save cash out of operating cash flow. Further analyses suggests that economic policy uncertainty affects corporate cash policy by influencing firms’ precautionary saving motives and the effect is larger when firms have difficulty in raising external finance. Using the new index developed by Baker et al. (2016), I extend the literature on economic policy uncertainty and show that it is an important macro-level factor in influencing corporate cash policy.     

Asymmetric volatility spillovers between economic policy uncertainty and stock markets: Evidence from China

This study explores the spillovers between economic policy uncertainty (EPU) and stock market realized volatility (RV). The monthly index of Chinese and US EPU and RV are used to analyze the pairwise directional spillovers. We find that RV is a net receiver that is more vulnerable to shocks from U.S. EPU than to shocks from Chinese EPU. We further decompose the RV into good and bad volatility to test the asymmetric spillover effect between the stock market and EPU. The results suggest that EPU has a bigger effect on bad volatility in the stock market throughout most of the sample period. However, we find that good volatility spillovers become larger during periods of stimulated reform, whereas bad volatility spillovers become larger during periods of international disputes. We show that Chinese stock market volatility is sensitive to both U.S. and Chinese EPU and that the spillover is asymmetric in different periods.     

Does managerial ownership influence corporate social responsibility (CSR)? The role of economic policy uncertainty

To explore the drivers of corporate social responsibility (CSR), we investigate how managerial ownership influences CSR in the presence of economic policy uncertainty. Our results demonstrate that, when facing more economic policy uncertainty (EPU), firms with larger managerial ownership invest significantly more in CSR. This is in agreement with the risk mitigation hypothesis, where CSR offers insurance‐like protection against adverse events. When economic policy uncertainty is not considered, however, we find that managers with higher ownership stakes invest significantly less in CSR, suggesting that CSR is driven by the agency conflict. As managers own more equity, they are subject to greater costs of CSR. Additional analyses confirm the results, including dynamic GMM, propensity score matching and instrumental‐variable analysis.     

Economic policy uncertainty and executive turnover

This paper examines whether economic uncertainty increases executive turnover. The negative perception perspective and business change theory suggest that executives are more likely to leave their jobs during periods of corporate distress. However, the additive effects of internal and external risk are thought to prompt firms to carefully consider executive turnover, thereby reducing the likelihood of executive changes. Based on the literature, we propose a check-and-balance hypothesis for the relationship between external uncertainty and executive change, according to which the optimal superposition of the internal and external risks stemming from increased external uncertainty would be to avoid a wave of executive departures. Using a sample of Chinese A-share listed companies from 2010 to 2019 and the China economic policy uncertainty index of Baker et al. (2013), we examine the impact of economic policy uncertainty on executive turnover and our results support the check-and-balance hypothesis. Our findings enhance our understanding of how economic policy uncertainty affects executive turnover, and enrich the literature on corporate risk management and strategic management.     

Economic policy uncertainty and stock price crash risk

This paper studies the impact of economic policy uncertainty on stock price crash risk using data from China. We develop a new index to measure Chinese economic policy uncertainty and find that economic policy uncertainty has a remarkable positive effect on stock price crash risk. However, the effect reverses later. The results also indicate that the positive effect of economic policy uncertainty on stock price crash risk is more prominent for state‐owned enterprises. Moreover, this effect is more prominent for firms with higher information asymmetry and firms with greater disagreement among investors, indicating that economic policy uncertainty affects crash risk through two mechanisms: managers’ concealment of bad news and investors’ heterogeneous beliefs.     

Economic policy uncertainty and credit growth: Evidence from a global sample

This study extends the research of Bordo, Duca, and Koch (2016) and Hu and Gong (2018) by examining the influences of economic policy uncertainty (EPU) at domestic and global levels on aggregate bank credit growth. The empirical analysis is conducted through both supply and demand side factors of bank credit growth in 22 economies over the period 2001–2015. This study employs different measures of EPU and applies panel-corrected standard errors (PCSE) and feasible generalized least squares (FGLS), which are suitable for unbalanced panel data models. Three principal findings are follows. First, higher level of EPU has negative impact on bank credit growth, which is significant for domestic EPU measures. Second, the positive change in EPU appears to have favorable effects on bank credit growth. The effects in both cases are different for the credit demand and supply sides. The findings suggest the need for appropriate measures to tackle bank credit risk-taking activities in uncertain conditions. Third, the impacts of EPU in emerging economies are negative and somewhat stronger than in advanced economies.     

Systemic risk,economic policy uncertainty and firm bankruptcies: Evidence from multivariate causal inference

The paper investigates causal relationships between systemic risk, economic policy uncertainty and firm bankruptcies, conditional on global volatility proxied by the VIX index, in a sample of 15 advanced and major emerging market economies during January 2008-June 2018. We test for Granger causality in time and frequency domains as well as dissect multivariate causal linkages in the dynamic complex system framework by applying a novel technique – convergent cross mapping (Sugihara et al., 2012). Based on strictly coincident results from all the three approaches, we find that systemic risk causes firm exit in Spain, while in the UK and the Netherlands bankruptcies are triggered by economic policy uncertainty. In South Korea and the USA, the VIX index causes the firm shutdown. For the rest of the countries, the causality inference provides less robust evidence. We argue that the magnitude of deleveraging by banks with respect to the private nonfinancial sector, proxied by the volatility of credit-to-GDP gaps, shapes the presence or absence of causal impact by systemic risk, economic policy uncertainty or the VIX index on bankruptcies.     

Does economic policy uncertainty raise corporate precautionary cash holdings? Evidence from China

Using China as the research setting, this paper investigates the relationship between economic policy uncertainty and corporate precautionary cash holdings. Empirical results show a U-shaped relation between economic policy uncertainty and corporate precautionary cash holdings. Empirical analysis, in terms of ownership structure, firm size, corporate competitiveness and geographical location, further shows that (i) the effects for economic policy uncertainty in both state-owned and non-state-owned enterprises are significant, but the effect is stronger for state-owned enterprises; (ii) such significant effect is also found more strongly in small and medium-sized enterprises and highly competitive enterprises; and (iii) the effects for eastern, central and western China are all statistically significant, but the effect is strongest for eastern China.     

Economic policy uncertainty and bank earnings opacity

Using a sample of U.S. banks and an index for economic policy uncertainty developed by Baker et al. (2016), we investigate whether economic policy uncertainty is systematically related to bank earnings opacity. When economic policy is relatively uncertain, it is easier for bank managers to distort financial information, as unpredictable economic policy changes make assessing the existence and impact of hidden “adverse news” more difficult for investors and creditors. Economic policy uncertainty also increases the fluctuation in banks’ earnings and cash flows, thus providing additional incentives and opportunities for bank managers to engage in earnings management. Our results show that uncertainty in economic policy is positively related to earnings opacity, proxied by the magnitude of discretionary loan loss provisions and the likelihood of just meeting or beating the prior year’s earnings, and negatively related to the level of accounting conservatism (i.e., the timeliness of recognition of bad news relative to good news). Collectively, our results suggest that economic policy uncertainty leads to greater earnings opacity. We also find that the impact of economic policy uncertainty on financial reporting distortion is less pronounced for stronger banks (i.e., banks with high capital ratios).     

Economic policy uncertainty and corporate inventory holdings: evidence from China

We investigate the impact of economic policy uncertainty (EPU) on corporate inventory holdings in China over the period 2007–2017. We find that EPU leads firms to significantly reduce inventory holdings and this effect is particularly pronounced among non-state-owned enterprises. The adjustment of inventory holdings enhances firms’ operating and market performance consequently. In addition, firms with greater financial constraints or stronger external governance are more affected by EPU. Further exploration shows that EPU induces high precautionary cash holdings, which crowds out inventories. Our results illustrate that firms reallocate between inventories and cash to cope with uncertainty associated with economic policy changes.     

Economic policy uncertainty: Persistence and cross-country linkages

This paper provides new evidence on the stochastic behaviour of the EPU (Economic Policy Uncertainty (EPU) index constructed by Baker et al. (2016) in six of the biggest economies (Canada, France, Japan, US, Ireland, and Sweden), and also on cross-country linkages, over the period from January 1985 to October 2019. For this purpose, it uses fractional integration/cointegration methods to measure the degree of persistence of the EPU and whether there exists a long-run equilibrium relationship linking the individual indices. This framework is much more general than the standard approaches based on the I(0)/I(1) dichotomy since it allows for fractional values of the integration/cointegration parameter and therefore does not impose restrictive assumptions on the dynamic behaviour of the individual series and their linkages. EPU is found to be in most cases a non-stationary, mean-reverting series which is characterised by long memory. Several breaks are also detected in each country. Finally, there is very little evidence of cross-country linkages. Our analysis provides fresh insights into the degree of persistence and the transmission of EPU shocks and has implications both for investors having to make risk management decisions and choose investment strategies and policymakers having to design effective macroeconomic policies.     

Economic policy uncertainty and financial statement comparability

We examine the implications of economic policy uncertainty (EPU) for financial statement comparability. We posit that the increased difficulty of estimating future cash flows and the increased opportunity for earnings management with increased EPU reduce the quality of earnings and its comparability. Consistent with this reasoning, we find a negative relation between earnings comparability and lagged EPU. Further, the association between EPU and comparability is more negative for firms that have poorer accruals quality and higher earnings volatility. We do not find that accounting policy choice is systematically related to the association between EPU and comparability. These results suggest that cross-sectional differences in accounting estimates rather than accounting policies influence the relation between EPU and comparability.     

The effect of economic policy uncertainty on investor information asymmetry and management disclosures

Investor uncertainty about firm value drives investors’ information collection and trading activities, as well as managers’ disclosure choices. This study examines an important source of uncertainty that likely cannot be influenced by most managers and investors: uncertainty about government economic policy. We find that this uncertainty is associated with increased bid-ask spreads and decreased stock price reactions to earnings surprises. Managers respond to this uncertainty by increasing their voluntary disclosures, but these disclosures only partly mitigate the bid-ask spread increase. We conclude that government economic policy uncertainty is an important component of firms’ information environments and managers’ voluntary disclosure decisions.
