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.     

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.     

Value and momentum from investors’ perspective: Evidence from professionals’ risk-ratings

We conduct a controlled experiment with financial professionals to examine more directly whether value and momentum reflect risk factors or mispricing. By eliciting their risk perceptions and return expectations for company stocks, we identify what constitutes a risky investment from the point of investors. Contrary to the risk factor hypothesis, value and momentum stocks are regarded as less risky. However, other factors, such as size and beta, fall in line with their traditional interpretation as risk factors. Consistent with empirical findings, we observe higher return expectations for momentum stocks, raising questions on analysts believing in a risk–return trade-off.     

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 matter for financial reporting quality? Evidence from the United States

Review of Quantitative Finance and Accounting - We examine the effect of economic policy uncertainty (EPU) on the financial reporting quality of US firms over 1999–2015. We use accruals-based...     

Do Chinese firms speculate during high economic policy uncertainty? Evidence from wealth management products

It has been well-documented that policy-related uncertainty has significant economic consequences. Studies show that US firms tend to delay investments and be conservative during periods of high economic policy uncertainty (EPU), but findings regarding Chinese firms suggest that they seem to act speculatively. This study examines the impact of policy uncertainty on firms' bank wealth management product (WMP) purchasing and helps better understand firm behaviour during high EPU. Using Chinese listed firms' bank WMPs purchasing data, we find that high EPU is associated with a higher probability of bank WMPs being purchased. Moreover, a 100% increase in EPU is associated with an 11.14% increase in average bank WMP holdings in the sample. We provide evidence that Chinese firms are not speculative, but prudent, and use bank WMP holdings to hedge the risk of policy uncertainty. Additionally, we show that financial constraints are the channels through which EPU affects bank WMP holdings.     

Is U.S. economic policy uncertainty priced in China's A-shares market? Evidence from market,industry, and individual stocks

This paper is motivated by Bali, Brown, and Tang (2017) who find U.S. economic policy uncertainty (EPU) is priced in the cross-section of U.S. stock returns, and uses weekly data from March 2006 to April 2016 to study whether shocks in U.S. EPU also influence prices of China's A-shares from a market, industry, and individual stock perspective. Our methodology relies on an ARMA (1,1) model to extract shocks in the U.S. EPU series and a GARCH (1,1) model to examine how returns of China's A-shares respond to these shocks after controlling for business conditions proxied by term and credit spread in China. Generally, we find that shocks in U.S. EPU significantly and negatively explain returns of Chinese A-shares with a lag of one week. In addition, the market index containing small and growth stocks is more sensitive to shocks in U.S. EPU than the index containing big and value stocks. Furthermore, we find that firms in manufacturing, information technology, and media industries in China are more sensitive to shocks in U.S. EPU, while firms in agriculture and real estate industries respond less to shocks in U.S. EPU. Finally, China's A-shares which decline more in response to shocks in U.S. EPU have higher returns, smaller market capitalization, weaker operating profitability, higher asset growth, and better past year's cumulative returns. Overall, our findings show that investors in the Chinese A-shares market require a premium to hold stocks that are sensitive to shocks in U.S. economic policy uncertainty.     

The impact of global economic policy uncertainty on portfolio optimization: A Black–Litterman approach

This paper investigates the asymmetric impact of global economic policy uncertainty (GEPU) on global asset allocation. We employ the Double Asymmetric GARCH-MIDAS (DAGM) model to examine the asymmetric effect of GEPU shocks on long-term volatilities of global equities, bonds, commodities, clean energy and Bitcoin. The GEPU-based volatility is used as a proxy for the uncertainty of the investor’s views in the Black-Litterman (BL) framework. Empirical results show that the BL model with GEPU-based views yields higher out-of-sample risk-adjusted returns than other traditional benchmarks in most cases. The findings suggest that investors should consider the influence of GEPU when making portfolio decisions.     

Economic policy uncertainty and analysts’ forecast characteristics

We examine the influence of economic policy uncertainty (EPU) on the characteristics of analysts’ earnings forecasts over a thirty-year period, spanning a wide variety of political and economic conditions. Motivated by both theory and empirical evidence that suggest a decline in the quality of the information environment for firms as EPU increases, we establish that analysts’ forecast errors increase with EPU, as does the degree of forecast dispersion. Increased error and dispersion persist after controlling for several competing sources of economy-wide uncertainty. Cross sectional analysis exploring heterogeneity in forecast quality across both analyst and firm characteristics establishes that forecast error and dispersion increase with EPU across a broad spectrum of firms and levels of analyst expertise. We control for analysts’ experience overall and the years spent covering a particular industry and firm. Five alternative methods for classifying firms as policy sensitive versus policy neutral provide consistent evidence that analyst forecast errors and dispersion increase with EPU, even for firms not deemed to be particularly sensitive to policy.     

Risk-sharing,market imperfections,asset prices: Evidence from China’s stock market liberalization

We examine the roles of risk-sharing and other factors in stock price revaluation during a recent liberalization episode in China. Consistent with the theoretical prediction that liberalizations reduce systematic risk, we find that risk-sharing explains approximately one-fourth of the price revaluation of investible stocks during the eight-month window between reform announcement and implementation. The firm-specific information generated by the reform is more efficiently priced into stocks that have a higher degree of market liquidity, information transparency, and informed trading.     

Does oil price uncertainty matter in firm innovation? Evidence from China

Inspired by the prevalence of firm innovation and substantial influence of international oil price uncertainty (OPU) on firm operation and decision-making, we investigate the influence of OPU on firm innovation. Using a sample of Chinese listed firms over the 2007–2019 period, our study reveals that OPU decreases firm innovation. This finding is consistent with the real options theory and the prospect theory. Mediation analysis shows that OPU could decrease firm innovation by increasing firms' financing constraints degree. Moreover, high-tech firms and those in highly competitive industries have fewer options to delay their innovation investments, we find that the adverse effects of OPU on their innovation are weaker. Finally, further analysis shows that government subsidies can help mitigate adverse effects of OPU on firm innovation. This paper reveals that OPU goes beyond the commonly known and understood regular indicator that shapes a firm's innovation activity and enriches firm-level evidence for the effects of OPU by highlighting the effects on long-term investment in intangible assets.     

Capturing short-term and long-term alpha of global bond portfolios: evidence from EUR-investors’ perspective

The main focus of this paper is the managerial skill or alpha of global bond funds. Analysis of the global bond market shows that both currency and bond-related returns are an integral part of the global fixed-income exposure. The present work deals with regression-based style analysis and other established methods in the bulk of finance journals literature, using both currency and fixed-income factors, and investigates the alpha of the globally invested fixed-income portfolios. There is empirical evidence that, between May 2007 and January 2015, global bond funds delivered significantly positive alpha. There is also an indication that periods of depreciation of the basis currency of the funds (EUR) improves fund performance, and market turmoil and negative events destroy alpha. During the Euro crisis and Fed tapering, the funds generated sustainable positive excess alpha. A division of the sample into two sub-samples gives more insight into the excess return. Additional robustness estimations deliver qualitatively similar results.     

How do economic policy uncertainty and geopolitical risk drive Bitcoin volatility?

We investigate how economic policy uncertainty (EPU) and geopolitical risks (GPR) impact Bitcoin volatility with respect to factors related to type and nationality of uncertainty, investigated period, relationship horizon and extreme conditions. Applying ARDL model and quantile regression for monthly data from August 2010 to September 2021, we reveal that June 2014 corresponds to a key date that marks a reversal in the investigated relationship. Furthermore, we show that the relationship between uncertainty and bitcoin volatility changes according to different factors. US uncertainty has short run effects on Bitcoin volatility, while China’s uncertainty has rather long run effects. Moreover, Bitcoin volatility responds in the same manner to US EPU and GPR, while, it responds differently to China's EPU and GPR. In extreme quantiles, we find that Bitcoin hedges against US EPU and GPR. Further, Bitcoin hedges against either individual or joint effects of US uncertainty, but not both.     

Empirical investigation of changes in policy uncertainty on stock returns—Evidence from China’s market

This study finds evidence that a rise in economic policy uncertainty (EPU) leads to a decline in stock returns in Chinese market; however, a positive coefficient was observed in the lagged EPU as stock prices rebound. This phenomenon also holds true for a rise in uncertainty innovations in fiscal policy, monetary policy, trade policy and global policy. The evidence leads to conclude that policy uncertainty premiums should be priced into China’s stock prices. An escalation of U.S. policy uncertainty has a significantly harmful effect on Chinese stocks regardless of whether firms are stated own or listed on U.S. market.     

Do green bonds and economic policy uncertainty matter for carbon price? New insights from a TVP-VAR framework

Green bond shocks and economic policy uncertainty are essential factors affecting macroeconomic development and green finance. In this paper, the time-varying parameter vector autoregressive (TVP-VAR) framework is used to analyze the monthly data of China from April 2014 to March 2022 and to investigate the dynamic impact of green bond shock and economic policy uncertainty on carbon prices. The results show that economic policy uncertainty and the impact of the green bond have significant time-varying and short-term effects on carbon price. In the short term, economic policy uncertainty has a significant positive impact on carbon price most of the time, while green bond has a significant negative impact on carbon price most of the time. Meanwhile, economic policy uncertainty and the impact of green bond on carbon price in Hubei and Guangdong are heterogeneous. In addition, we also use Bayesian VAR (BVAR) model to test the robustness of the results. Based on the research results, some policy suggestions are put forward, including improving the stability of economic policies, implementing green bond support policies, and speeding up the improvement of the national unified carbon emission trading market.     

Industry policy,investor sentiment,and cross-industry capital flow: Evidence from Chinese listed companies’ cross-industry M&As

This study investigates how the government’s industry policies affect investor sentiment, and whether the influenced investor sentiment guides corporate capital flow in the real economy. By examining a sample of cross-industry mergers and acquisitions (M&As) of Chinese listed companies, we find that industry policies promulgated by the government have a significant asymmetric influence on investor sentiment. Furthermore, investor sentiment under the exogenous shock of industry policies has a significant real effect on companies’ cross-industry M&A behavior, generating cross-industry capital flow. Additional analyses reveal that this effect arises because the acquirer depends on equity financing and has incentive to cater to investor sentiment. Our findings help clarify the effect of public policies on the stock market, theoretically, from the company’s micro-level perspective, as well as the mechanism by which stock market volatility transmits to the real economy.     

Does global economic uncertainty matter for the volatility and hedging effectiveness of Bitcoin?

We assess whether the long-run volatilities of Bitcoin, global equities, commodities, and bonds are affected by global economic policy uncertainty. Empirical results provide evidence supporting this hypothesis, except in the case of bonds. For Bitcoin investors, the results imply the ability to use information about the state of global economic uncertainty to enhance the predictions of Bitcoin volatility. We further examine whether the correlation between Bitcoin and global equities, commodities, and bonds are affected by global economic policy uncertainty. Empirical results reveal that global economic policy uncertainty has a negative significant impact on the Bitcoin-bonds correlation and a positive impact on both Bitcoin-equities and Bitcoin-commodities correlations, suggesting the possibility of Bitcoin acting as a hedge under specific economic uncertainty conditions. Interestingly, the hedging effectiveness of Bitcoin for both global equities and global bonds enhances slightly after considering the level of global economic policy uncertainty. Such a weak effect of the state of global economic uncertainty on the hedging ability of Bitcoin implies that investors cannot substantially enhance the hedging performance of Bitcoin under different economic uncertainty conditions.     

New development: Faith and foreign policy—a perspective from the Vatican

Religion matters in foreign policy as much as it does in domestic society and, to understand the world in which we live, we have to comprehend religion as a source of influence and motivation in people's lives. That is not always easy for foreign policy specialists and diplomats. Britain's relations with the Holy See go back to 1479 when England sent its first resident ambassador overseas. The Holy See is one of the world's most global bodies—touching directly 17.5% of the world's population through the Catholic Church. It is a unique hybrid of the global and the local, which helps to form global public opinion. Today, the UK's oldest embassy is working on a whole range of issues with the Holy See from tackling climate change, disarmament, international development, interfaith dialogue and preventing and ending conflict.     

Investor flow-chasing and price–performance puzzle: Evidence from global infrastructure funds

Despite the importance and peculiarity of the infrastructure fund, determinants of infrastructure fund flow and the relation between fees and fund performance were poorly understood. This paper documents two new findings using a unique dataset for global infrastructure funds from January 2005 to June 2019. First, investor flow-chasing exists at the level of infrastructure fund companies, which is intensified by the opacity of information and uncertainty of returns. Second, infrastructure funds charge higher fees even when their before-fee performance is worse, which is explained by fund characteristics and year effects. Based on these findings, we put forward countermeasures from the perspectives of investors, regulators, investor protection managers, and fund managers, with incentive mechanism reforms to alleviate the price-performance puzzle, thereby improving the efficiency of infrastructure fund portfolios.     

Banks’ interconnections and peer effects: Evidence from Chile

In this paper, we identify and quantify the importance of endogenous peer effects in the interbank market, allowing for varying degrees of intensity of these peer effects. We base our analysis on a unique dataset that includes all interbank loans that have taken place between 15 banks in the Chilean interbank market representing more than 95% of the market between 2009 and 2016. This approach contrasts sharply with the geographical definition of peers used by most of the literature. As an application of our model, we examine an episode of liquidity shortage experienced by one Chilean bank in the interbank market, with the lenses of our model. We show evidence consistent with a herding behavior of the lender banks which, according to our model, were peers of the stressed bank.
