Did the National Minimum Wage Affect UK Prices?*

One potential channel through which the effects of the minimum wage could be directed is that firms that employ minimum‐wage workers could have passed on any higher labour costs resulting from the minimum wage in the form of higher prices. This study looks at the effects of the minimum wage on the prices of UK goods and services by comparing prices of goods and services produced by industries in which UK minimum‐wage workers make up a substantial share of total costs with prices of goods and services that make less use of minimum‐wage labour. Using sectoral‐level price data matched to Labour Force Survey data on the share of minimum‐wage workers in each sector, it is hard to find much evidence of significant price changes in the months that correspond immediately to the uprating of the national minimum wage. However, over the longer term, prices in several minimum‐wage sectors – notably, take‐away food, canteen meals, hotel services and domestic services – do appear to have risen significantly faster than prices in non‐minimum‐wage sectors. These effects were particularly significant in the four years immediately after the introduction of the minimum wage.     

Explaining stock markets' performance during the COVID-19 crisis: Could Google searches be a significant behavioral indicator?

The purpose of this study is to examine the impact of the pandemic on the performance of stock markets, focusing on the behavioral influence of the fear due to COVID-19. Using a data set of 10 developed countries during the period December 31, 2019, to September 30, 2020, we examine the impact of COVID-19 on the performance of the stock markets. We incorporate the impact of the COVID-19 pandemic using the following variables: (a) the number of new COVID-19 cases, which was widely used as the main explanatory variable for market performance in early financial studies, and (b) a Google Search index, which collects the number of Google searches related to COVID-19 and incorporates the health risk and the fear of COVID-19 (the higher the number of searches for Covid terms, the higher the index value, and the higher the fear index). We employ our input into an EGARCH(1,1,1) model, and the findings show that the Google Search index enables us to draw statistically significant information regarding the impact of the COVID-19 fear on the performance of the stock markets. On the other hand, the variable of the number of new COVID-19 cases does not have any statistically significant influence on the performance of the stock markets. Google searches could be a useful tool for supporters of behavioral finance, scholars, and practitioners.     

Does Index Speculation Impact Commodity Prices? An Intraday Analysis

Using intraday data, we find unidirectional causality from commodity index‐linked futures to nonindex‐linked commodity futures for up to one hour which disappears when using daily data. Also, the economic significance of index‐linked to nonindex commodity transmission declines to zero within about an hour. Finally, we find that the magnitude of index‐linked to nonindex return transmission is positively related to the amount of speculation, both long and short, in S&P GSCI commodity index futures. We conclude that speculative pressures exerted by commodity index futures can impact nonindex commodities, mainly through the activity of uninformed, positive feedback traders.     

Does real flexibility help firms navigate the COVID-19 pandemic?

Building on the investment-based asset pricing framework, we show that firms' ability to timely scale down their operations reduces the sensitivity of their equity value to large adverse productivity shocks. Using U.S. data in the times of the COVID-19 pandemic, we provide empirical evidence consistent with our model's predictions. Real flexibility curbs losses in firm value and reduces return volatility, especially for firms with high book-to-market or high COVID-19 exposure, consistent with the idea that the benefits of real flexibility are associated primarily with contraction options during the COVID-19 crisis. Our analysis shows that real flexibility provides incremental and complementary protection beyond financial flexibility. Besides its impact on stock prices, real flexibility also helps firms sustain earnings during 2020, compared with 2019 when the pandemic had not struck. Our work demonstrates that real flexibility is an important tool for corporate managers in navigating episodes of disasters.     

Gold or Bitcoin,which is the safe haven during the COVID-19 pandemic?

This study compares the dynamic spillover effects of gold and Bitcoin prices on the oil and stock market during the COVID-19 pandemic via time-varying parameter vector autoregression. Both time-varying and time-point results indicate that gold is a safe haven for oil and stock markets during the COVID-19 pandemic. However, unlike gold, Bitcoin's response is the opposite, rejecting the safe haven property. Further analysis shows that the safe-haven effects of gold on the stock market become stronger when the pandemic critically spreads.     

Does technology-seeking OFDI improve the productivity of Chinese firms under the COVID-19 pandemic?

This paper empirically investigates the impact of technology-seeking outward foreign direct investment (OFDI) on firms' productivity under the influence of negative external shocks, taking as a sample the investment data of Chinese firms before and during COVID-19. The results show that technology-seeking OFDI improves productivity, but not under negative external shocks. The dampening effect of such shocks is more significant when the host country is a developed country and in firms with multiple branches. Technology-seeking OFDI particularly improves the productivity of research and development and processing firms, and (among the productivity measures tested) most prominently affects total factor productivity.     

Does CSR matter in times of crisis? Evidence from the COVID-19 pandemic

The debate over how firm stakeholder engagement is tied to preserving shareholder wealth has received growing attention in recent years, especially in the wake of the COVID-19 crisis. Against this backdrop, we examine the relation between corporate social responsibility (CSR) and stock market returns during the COVID-19 pandemic-induced market crash and the post-crash recovery. Using a sample of 1750 U.S. firms and two major sources of CSR ratings, we find no evidence that CSR affected stock returns during the crash period. This result is robust to various sensitivity tests. In additional cross-sectional analysis, we find some supporting evidence, albeit weak, that the relation between CSR and stock returns during the pandemic-related crisis is more positive when CSR is congruent with a firm's institutional environment. We also find that Business Roundtable companies, which committed to protecting stakeholder interests prior to the pandemic, do not outperform during the pandemic crisis. We conclude that pre-crisis CSR is not effective at shielding shareholder wealth from the adverse effects of a crisis, suggesting a potential disconnect between firms' CSR orientation (ratings) and actual actions. Our evidence suggests that investors can distinguish between genuine CSR and firms engaging in cheap talk.     

Capture the contagion network of bitcoin – Evidence from pre and mid COVID-19

COVID-19 is the first global scale crisis since the inception of Bitcoin. We compare the contagion phenomenon of Bitcoin and other financial markets or assets pre and during the COVID-19 shock in both contemporaneous and non-contemporaneous manner. This paper uses the directed acyclic graph (DAG), spillover index, and network topology to provide strong evidence on the directional contagion outcomes of Bitcoin and other assets. The empirical results show that the contagion effect between Bitcoin and developed markets is strengthened during the COVID-19 crisis. Particularly, European market has a dominant role. Excluding Bitcoin’s own shocks, United State and European markets are the main contagion sources to Bitcoin. European market also works as a intermediary to deliver infectious from United State and market fear. The findings show that gold always has contagion effect with Bitcoin, while gold, US dollar and bond market are the contagion receivers of Bitcoin under the shock of COVID-19. The empirical results further proved the safe haven, hedge and diversifier potential of Bitcoin in economic stable time, but also shows that the sustainability of these properties is undermined during the market turmoil.     

Does the Quality of Financial Advice Affect Prices?

Using a large data sample of 58,562 new municipal issues covering the period from 1984 to 2002, we examine whether the quality of advice provided by a financial advisor affects new issue interest costs. We find that higher‐quality financial advisors are associated with statistically significant decreases in new issue yields. The effect of advisor quality on yields is more pronounced for revenue, negotiated, and opaque bond issues than for general obligation and competitively sold issues. However, issuers of revenue or negotiated bonds are more likely to choose a low‐quality advisor.     

What can we learn about the market reaction to macroeconomic surprise? Evidence from the COVID-19 crisis

We investigate the impact of macroeconomic surprise and uncertainty on G7 financial markets around COVID-19 pandemic using two real-time, real-activity indexes recently constructed by Scotti (2016). We applies the wavelet analysis to detect the response of the stock markets to the macroeconomic surprise and an uncertainty indexes and then we use NARDL model to examine the asymmetric effect of the news surprise and uncertainty on the equity markets. We conduct our empirical analysis with the daily data from January, 2014 to September, 2020. Our findings indicate that G7 stock markets are sensitive to the macroeconomic surprise and uncertainty and the effect is more pronounced at the long term than the short term. Moreover, we show that the COVID-19 crisis supports the relationship between the macroeconomic indexes and the stock prices. The results are useful for investment decision-making for the investors on the G7 stock indices at different investment horizons.     

COVID-19 social distancing and the US service sector: What do we learn?

This study investigates the impact of COVID-19 social distancing on the US service sector. Results from four industry indexes (hotels, entertainment, restaurants and airlines) indicate that conditional correlations among index pairs exhibited substantial increases. Iterated Cumulative Sums of Squares (ICSS) tests in dynamic conditional correlations show that while the relationship between airlines and entertainment venues is unstable, restaurants and hotels demonstrate stable co-movement. Markov regime-switching regression analysis suggests the pandemic is affecting mainly the entertainment and airline industries, with gradual deterioration in the hotel industry, led by small-market-cap companies. However, we see no evidence of a negative impact on the restaurant industry from the pandemic in our analysis period. This may be related to Maslow's hierarchy of needs. Based on our results, we recommend employment of effective working capital and supply chain management methods in the service sector to streamline the operations of affected companies. In addition, all other sectors should utilize appropriate methods of risk measurement and should take 'Black Swans' into account to incorporate a more accurate probability of unexpected events.     

Does COVID-19 open a Pandora's box of changing the connectedness in energy commodities?

With the rapid spread of coronavirus, the global financial markets have been undergoing tremendous changes, which bring investors more risks in the short term. Against such background, this study concentrates on the far-reaching energy commodities, aiming to explore the impact of COVID-19 on cross-market linkages. To capture the dynamic nature of interdependence, we applied the TVP-VAR based connectedness index method and individually focused on the total, net, and pairwise connectedness. The empirical results show that there is a dramatic rise in the total connectedness in energy markets following the outbreak of COVID-19, but this change only lasted about two months and then fell back to the prior level. Further analyzing the net spillover conditions, we find that the connectedness structure has also displayed some temporary changes. At last, the spillover networks indicate that there are only three pairwise connectedness relations have changed in direction before and after the outbreak of COVID-19. We also try to discuss the underlying COVID-19 shock propagation mechanism, and the results suggest the significant mediation effect of the financial panic risk. In general, our study offers several urgent and prominent implications to understand the financial impact of COVID-19.     

How do firms learn? Evidence from corporate cash holdings during the COVID-19 pandemic

We examine the impact of COVID-19 on US corporate cash holdings. Our findings suggest that greater pandemic exposure is associated with higher corporate cash holdings and that firms learn from prior experiences as they manage their cash policies. More specifically, the level of cash holdings in firms that experienced severe financial constraints during the 2008 credit crisis and firms with prior severe acute respiratory syndrome (SARS) and H1N1 exposure is significantly lower than that of firms with no prior epidemic or financial constraints experience. Overall, our findings support the learning behaviour of cash and contribute to corporate cash holdings literature by providing insights on the extent to which firms learn from prior experiences to manage their liquidity.     

Do Prices Reveal the Presence of Informed Trading?

Using a comprehensive sample of trades from Schedule 13D filings by activist investors, we study how measures of adverse selection respond to informed trading. We find that on days when activists accumulate shares, measures of adverse selection and of stock illiquidity are lower, even though prices are positively impacted. Two channels help explain this phenomenon: (1) activists select times of higher liquidity when they trade, and (2) activists use limit orders. We conclude that, when informed traders can select when and how to trade, standard measures of adverse selection may fail to capture the presence of informed trading.     

How does the COVID-19 pandemic shape the relationship between Twitter sentiment and stock liquidity of US firms?

Using a new investor sentiment metric derived from Twitter, this paper examines how the pandemic's death rate influences the impact of investor sentiment on stock liquidity. Recent literature remains inconclusive regarding the effect of COVID-19 information and investor sentiment on financial markets. Using panel smooth transition regression (PSTR) for daily data on 338 listed firms in the S&P500 from January 2, 2020, to May 26, 2021, the findings reveal that the impact of Twitter sentiment on stock liquidity is nonlinear and changes over time and across firms in the function of the pandemic's death rate in the US. The results exhibit a threshold level of 4.32%, above which investor sentiment boosts stock liquidity. The speed of the transition from low to high pandemic death rate regime occurred abruptly rather than smoothly. This translates to severe changes in investor perception and demonstrates that investors are rapidly updating their beliefs during the COVID-19 outbreak.     

Do currency exchange rates impact gold prices? New evidence from the ongoing COVID-19 period

We apply the nonlinear autoregressive distributed lag method to examine the relationships between seven leading currency exchange rates and gold prices using daily data from January 2017 to April 2021. The results reveal that in the short term, while negative United States dollar (USD) to United Kingdom pound, negative USD to Canadian dollar, negative USD to Japanese yen, negative USD to Danish krone, and positive USD to euro exchange rates increase gold prices, a lagged positive USD to euro and lagged positive USD to Danish krone exchange rates decrease gold prices. A test of the pre-pandemic normal period reveals that the uneven and unpredictable impacts of six exchange rates on gold prices are particularly due to COVID-19. We find efficiency in the gold market, in line with the market efficiency hypothesis and random walk theory. Our findings indicate that gold acts as a safe-haven asset for investors during COVID-19.     

投资者情绪与股票市场——基于COVID-19疫情突发事件

为分析投资者情绪对股票市场存在何种具体影响,本文结合COVID-19疫情突发事件,研究了投资者情绪对股票市场的影响,以及COVID-19疫情发生前后这些影响的改变,并进一步分析了新闻情绪和投资者关注对影响的调节作用。研究结果表明,投资者关注、情绪及新闻情绪均对股票市场收益率和换手率存在显著影响。此外,COVID-19疫情的发生使收益率更容易受到投资者情绪的影响,且投资者关注会加强投资者情绪对收益率的影响,而新闻情绪对影响不存在调节效应。     

Bitcoin’s price efficiency and safe haven properties during the COVID-19 pandemic: A comparison

As the COVID-19 outbreak became a global pandemic, traditional financial market indicators were significantly affected. We examine the price efficiency and net cross-correlations among Bitcoin, gold, a US dollar index, and the Morgan Stanley Capital International World Index (MSCI World) during the four months after the World Health Organization officially designated COVID-19 as a global pandemic. Using intraday data, we find that Bitcoin prices were more efficient than the US dollar and MSCI World indices. Using a detrended partial-cross-correlation analysis, our results show that net cross-correlations vary across time scales. Our results suggest that when the time scale is greater than two months, gold can be considered as a safe haven for investors holding the MSCI World and US dollar indices and when the time scale exceeds three months, Bitcoin can be considered a safe haven for the MSCI World index.     

Are safe haven assets really safe during the 2008 global financial crisis and COVID-19 pandemic?

This study evaluates the safe-haven role of twelve assets against the US stock market during the 2008 global financial crisis (GFC) and the COVID-19 pandemic. Our results show that silver and the Islamic stock index were safe havens during the 2008 GFC, and the Islamic stock index and Tether have been safe havens during COVID-19. We observe that the Islamic stock index and Tether have emerged as strong new safe havens. However, our supplementary analysis reveals that gold and Bitcoin still exhibit safe-haven behavior during severe market downturns. Overall, our findings suggest that safe-haven assets may vary over time.
