Spillovers and connectedness among BRICS stock markets,cryptocurrencies, and uncertainty: Evidence from the quantile vector autoregression network

In this study we advance the understanding of the spillovers and connectedness network among conventional and Islamic BRICS stock markets, cryptos (Bitcoin, Ethereum, Litecoin) and various global uncertainties, using a quantile vector autoregression method and daily data covering the period October 8, 2016, to May 28, 2021. Further, the study uses a network and sensitivity analyses to assess the nexus, examines risk causes, and the transfer paths in these markets under bearish, normal, and bullish markets. The evidence offers major findings. First, the overall static and dynamic connectedness is very high and more intense at extreme events. Second, the network connectedness structure shows that the markets have played both roles: net transmitters and receivers of shocks under several market states. Finally, the sensitivity to quantiles analysis shows switching behavior of net transfer spillovers over the quantiles. This could be beneficial to investors aiming at optimizing hedging strategies. Policymakers should consider carefully the overall network connectedness in the market system and formulate appropriate policies to conceive stock market price sensitivity.     

Intertemporal substitution in the Spanish economy: Evidence from regional data

This paper studies the intertemporal substitution in consumption and leisure for the Spanish economy by estimating the first‐order conditions of an individual optimization model with regional and aggregate data. While first‐order conditions determining intertemporal substitution in consumption show a good econometric fit, and the value we obtain for the intertemporal elasticity of substitution is similar to previously available results, the econometric fit of the intertemporal condition in leisure indicates that the behaviour of the Spanish labour supply over the cycle is more complex than can be explained by the canonical intertemporal choice model.     

Current account sustainability in G7 and BRICS: Evidence from a long-memory model with structural breaks

In this paper, we extend the existing literature on current account sustainability by examining the relevance of long memory and structural breaks in modelling the dynamics of current account to gross domestic product (GDP) ratios in G7 and BRICS. Unlike standard unit root tests, which have low power, especially in cases where the series is characterized by a fractional process, the long-memory approach provides an exact measure of the degree of persistence. However, long-memory models are known to overestimate the degree of persistence of the series in the presence of structural breaks. We show that regime changes do exist in both the mean and trend of the current account to GDP ratios. Thus, we test persistence allowing for both smooth and sharp breaks. Our methodology also allows any number of sharp breaks, whereas standard unit root tests only permit either one or two breaks. Hence, our approach is more general and more robust to misspecifications caused by the omission of breaks than standard methods. We show that current accounts are sustainable in both groups of countries, with the G7 and South Africa displaying long-memory behaviour.     

The impact of crude oil inventory announcements on prices: Evidence from derivatives markets

This study examines the impact of weekly crude oil storage announcements on oil futures and options prices. We document evidence of a strong announcement day effect on both markets, and find prices to move in anticipation of the inventory surprise. Futures returns significantly decrease with positive surprises and increase with negative surprises. There is no evidence of an asymmetric impact on futures prices. Near‐the‐money options exhibit the greatest price sensitivity, and the magnitude of the price response of both futures and options declines with maturity. The results remain robust even after controlling for various macroeconomic and other storage‐related news variables.     

Political Risk and Export Promotion: Evidence from Germany

Political risk represents an important hidden transaction cost that reduces international trade. This paper investigates the claim that public export credit guarantees mitigate this friction to trade flows and hence promote exports. We employ an empirical trade gravity model, where we explicitly control for political risk in the importing country in order to evaluate the effect of export guarantees. Using a novel data set on guarantees, we estimate the effect of guarantees in a static and dynamic panel model. We find a statistically and economically significant positive effect of public export guarantees on exports which indicates that export promotion is indeed effective. Furthermore, political risk turns out to be an important obstacle for exports and hence should be taken into account in any empirical model of trade.     

Informed trading around merger and acquisition announcements: Evidence from the UK equity and options markets

This paper offers new evidence on informed trading around merger and acquisition announcements from the UK equity and options market. The analysis suggests that in about 25–33% of events there is abnormal option trading volume during the month that precedes the announcement. Such evidence is found in both call and put option volumes, is robust to different “estimation” and “event window” lengths, to different sub‐samples, and to liquidity considerations. These results support the argument that informed investors will transact in both the options and the stock market, and are comparable to results reported by the FSA in the cash market. © 2010 Wiley Periodicals, Inc.

Corporate Philanthropy and Stock Price Crash Risk: Evidence from China

How to mitigate stock price crash risk has become a focus in the theoretical and practical fields. Building on the work of Kim et al. (J Bank Finance, 43:1–13, 2014b), this paper investigates the relation between corporate philanthropy and crash risk under the unique Chinese institutional background. The results show that both state ownership and the 2005 split share reform attenuate the mitigating effect of corporate philanthropy on crash risk. Specifically, the negative relation between corporate philanthropy and crash risk is less pronounced for state-owned enterprises than for non-state-owned enterprises, and it is also less pronounced after firms accomplish the split share reform. Further, this effect is more pronounced for firms with greater financial risks and poorer performance. Our paper contributes to the growing literature on the determinants of stock price crash risk and the economic consequences of corporate philanthropy. It also offers useful guidance to firms that are seeking to reduce stock price crash risk in emerging markets.     

Large Shareholder Tunneling and Risk of Stock Price Crash： Evidence from China

Although several studies have examined the economic consequences of large shareholders＇ tunneling behavior, little attention has been paid to the negative effects of tunneling on firms＇ extreme events. In this article, we investigate how tunneling behavior affects firm-level stock price crashes. The findings indicate that the probability of stock price crashes is positively associated with the extent of tunneling behavior by large shareholders. The positive relationship is more pronounced after the split of share structure reform and is moderated by the firm＇s financial conditions. This study contributes to the emerging body of literature focusing on the economic consequences of tunneling and stock price crashes. The conclusions drawn from the study also provide a frame of reference for investor protection and investment portfolios based on large shareholders＇ tunneling behavior in China.

Risk spillover of banking across regions: Evidence from the belt and road countries

We present the risk spillover effect of 2178 banks in 63 countries along the Belt and Road from 2006 to 2020 with the VAR-BEKK-GARCH model. We find that Chinese banking has two-way risk contagion with banks in East Asia and Association of Southeast Asian Nations, South Asia, West Asia, and Central Asia. Furthermore, Chinese banking keeps a positive correlation with banks in Thailand, Turkey, and Saudi Arabia, and its relationship with Indonesia and Kazakhstan shows seasonal characteristics, whereas with India, there is no obvious spillover effect.     

Disclosure of Downside Risk and Investors' Use of Qualitative Information: Evidence from the IPO Prospectus's Risk Factor Section

I use the context of a company's initial public offering (IPO) of equity securities as a capital‐market setting to empirically study the economic consequences of risk factor disclosures. Using data from Australian IPOs, I examine the relation of textual risk disclosures in the prospectus to initial underpricing. I find that the quantity of disclosures in the risk factor section itself has no significant impact on initial underpricing. However, an increase in the informativeness of risk factor disclosures is associated with lower IPO underpricing. My results suggest that IPOs that provide informative risk factor disclosures have less ex ante uncertainty, in the sense that the disclosures help investors estimate the dispersion of secondary market value. The effect of informative risk factor disclosures on IPO underpricing is more pronounced for IPOs with less prestigious lead underwriters and is mainly driven by younger firms, smaller firms, and firms with poorer operating performance prior to their IPOs. Collectively, my findings suggest that informative disclosures of downside risk are useful for investors to evaluate IPOs.     

The Effect of Diversification on Tail Risk: Evidence from US Equity Mutual Fund Portfolios

This paper examines the effect of diversification on the tail risk of US equity mutual fund portfolios by utilizing classical higher‐moment measures and robust tail weight measures. Empirical results show that market standard portfolios based on the mean‐variance framework are exposed to greater tail risk than benchmark portfolios are and diversification further intensifies this exposure.     

Linking Ethics and Risk Management in Taxation: Evidence from an Exploratory Study in Ireland and the UK

Ethical dilemmas involving tax issues were identified by members of the American Institute of Certified Public Accountants as posing the most difficult ethical problem for them (Finn et al., Journal of Business Ethics 7(8), pp. 607–609, 1988). The KPMG tax shelter fraud case proves that the tax profession has not gone untainted in the age of numerous accounting and corporate scandals, such as the Enron débacle (Sikka and Hampton, Accounting Forum 29(3), 325–343, 2005). High-profile scandals serve to highlight the problems caused by differences in ethical judgement among accountants and tax practitioners and the issue of ethics has been brought publicly to the forefront of the profession. Nevertheless, the nature and dimension of ethical issues in tax practice have been largely unexplored (Erard, Journal of Public Economics 52(2), 163–197, 1993; Marshall et al., Journal of Business Ethics 17(12), 1265–1279, 1998; Frecknall Hughes, Unpublished PhD Thesis, The University of Leeds, 2002). This research aims to contribute to the debate on ethics in tax practice by reporting interview data on tax practitioners’ perceptions of ethics in the jurisdictions of Ireland and the United Kingdom and exploring the link or equation of ethics with risk management.     

Domestic mergers and acquisitions in BRICS countries: Acquirers and targets

We study the firm value determinants for domestic acquisitions within BRICS countries considering both acquirer and target shareholders. Targets earn significant positive announcement returns of 1.45% on average. Acquirers lose slightly. We employ a comprehensive set of explanatory variables and test for cross-sectional return drivers. Target returns are negatively related to pre-announcement returns and firm size, while they are positively related to GDP growth. Our results are consistent with insider trading capturing some of the target excess returns, which are highest for small targets based in countries with high recent GPD growth.
