Is warrant really a derivative? Evidence from the Chinese warrant market

This paper studies the Chinese warrant market that has been developing since August 2005. Empirical evidence shows that the market prices of warrants are much higher systematically than the Black-Scholes prices with historical volatility. The prices of a warrant and its underlying asset do not support the monotonicity, perfect correlation and option redundancy properties. The cumulated delta-hedged gains for almost all expired warrants are negative. The negative gains are mainly driven by the volatility risk, and the trading values of the warrants for puts and the market risk for calls. The investors are trading some other risks in addition to the underlying risks.     

Is market fragmentation harming market quality?

We examine how fragmentation is affecting market quality in US equity markets. We use newly available trade reporting facilities (TRFs) data to measure fragmentation, and we use a variety of empirical approaches to compare execution quality and efficiency of stocks with more and less fragmented trading. We find that fragmentation affects all stocks; more fragmented stocks have lower transactions costs and faster execution speeds; and fragmentation is associated with higher short-term volatility but greater market efficiency, in that prices are closer to being a random walk. Our results that fragmentation does not appear to harm market quality are consistent with US markets being a single virtual market with multiple points of entry.     

Are stock markets really efficient? Evidence of the adaptive market hypothesis

This study examines the adaptive market hypothesis in the S&P500, FTSE100, NIKKEI225 and EURO STOXX 50 by testing for stock return predictability using daily data from January 1990 to May 2014. We apply three bootstrapped versions of the variance ratio test to the raw stock returns and also whiten the returns through an AR-GARCH process to study the nonlinear predictability after accounting for conditional heteroscedasticity through the BDS test. We evaluate the time-varying return predictability by applying these tests to fixed-length moving subsample windows and also examine whether there is a relationship between the level of predictability in stock returns and market conditions. The results show that there are periods of statistically significant return predictability, but also episodes of no statistically significant predictability in stock returns. We also find that certain market conditions are statistically significantly related to predictability in certain markets but each market interacts differently with the different market conditions. Therefore our findings suggest that return predictability in stock markets does vary over time in a manner consistent with the adaptive market hypothesis and that each market adapts differently to certain market conditions. Consequently our findings suggest that investors should view each market independently since different markets experience contrasting levels of predictability, which are related to market conditions.     

Is the venture capital market liquid? Evidence from India

This paper models investment duration in the Indian venture capital (VC) market, by industry and exit route. We examined 3416 investment and exit transactions in India during the period 2000–2017 and found that the probability of staying invested for more than ten years was 70%. Exit probabilities were low in most sectors. Investment duration was not positively associated with the investment valuation; rather, it was impossible to exit from the majority of investments because of the illiquidity of the VC market.     

Informal or formal financing? Evidence on the co-funding of Chinese firms

Different modes of external finance provide heterogeneous benefits for the borrowing firms. Informal finance offers informational advantages whereas formal finance is scalable. Using unique survey data from China, we find that informal finance is associated with higher sales growth for small firms but lower sales growth for large firms. We identify a complementary effect between informal and formal finance for the sales growth of small firms, but not for large firms. Co-funding, thereby simultaneously using the informational advantage of informal finance and the scalability of formal finance, is therefore the optimal choice for small firms.     

Does debtor protection really protect debtors? Evidence from the small business credit market

This paper analyzes how different levels of debtor protection across US states affect small firms’ access to credit, as well as the price and non-price terms of their loans. We use an individual-specific measure of debtor protection that has its maximum value when the borrower’s home equity is lower than the state homestead exemption (the debtor’s home equity is fully protected), and is decreasing in the difference between the home equity and the homestead exemption (the amount that the creditor can seize). We find that unlimited liability small businesses have lower access to credit in states with more debtor-friendly bankruptcy laws. In addition, these businesses face tighter loan terms - they are more likely to pledge business collateral, have shorter maturities, and borrow smaller amounts. For limited liability small businesses, we also find a reduction in credit availability, but of smaller magnitude, together with an increase in the loan rate.     

Is less information better information? Evidence from the credit rating withdrawal

This paper examines the stock market reaction to two different types of credit rating withdrawals by Moody’s. The first type of withdrawal occurs when a firm stops being rated. This happens, for example, when firms choose to no longer pay for a rating. We find that the stock market reaction depends on the information which remains available. The second type of withdrawal is due to Moody’s policy of removing the issuer rating and keeping the corporate family rating for the same firm. The corporate family rating is usually more favorable than the issuer rating. The paper shows that the removal of the issuer rating leads to positive stock market reaction. We conclude that lower disclosure of rating information is not necessarily associated with higher cost of equity. Instead, our findings emphasize the incentive for firms to engage in ratings shopping by publishing only the most favourable ratings.     

Do auditors’ early-life socioeconomic opportunities improve audit quality? Evidence from China

Prior research documents significant variation in audit outcomes based on individual auditors' demographic features, working experience, educational background, and social connections. This study examines whether individual auditors' early-life socioeconomic opportunities also affect audit practices. We expect that auditors from big cities have more access to socioeconomic opportunities and accumulate more human capital in early life, thus are more capable of providing high-quality audits after they start careers. Consistent with this hypothesis, we find that auditors from big cities make more audit adjustments to earnings compared with auditors from small towns. Additional tests suggest that this early-life effect on audit quality is moderated when auditors receive higher education or gain more auditing experience and is more pronounced in downward adjustments than in upward adjustments. We also find a fee premium for auditors from big cities. Overall, this paper provides evidence that auditors’ early-life socioeconomic opportunities have a far-reaching influence on audit quality.     

Does Fintech facilitate cross-border M&As? Evidence from Chinese A-share listed firms

This paper examines whether and how financial technology (Fintech) affects the cross-border M&A decision-making and the performance of acquiring firms. Using a sample of Chinese A-share listed firms over the period of 2011–2019, we find that local Fintech development effectively facilitates firms' cross-border M&A activities. This effect is more prominent for firms with lower innovation capability, with higher profitability, and those in key participant provinces of the Belt and Road Initiative. We provide evidence that Fintech supports the decision-making of cross-border M&As due to the mitigation of financing friction and the decrease in information disadvantage. Further analysis also shows that the acquirer's cross-border M&A performance is higher when it is located in a province with better development of Fintech. Our paper provides new insights into the impact of technology-enabled innovation in the financial industry on the behavior of firms in non-financial industries.     

Do extreme returns matter in emerging markets? Evidence from the Chinese stock market

Recent evidence in the U.S. and Europe indicates that stocks with high maximum daily returns in the previous month, perform poorly in the current month. We investigate the presence of a similar effect in the emerging Chinese stock markets with portfolio-level analysis and firm-level Fama–MacBeth cross-sectional regressions. We find evidence of a MAX effect similar to the U.S. and European markets. However, contrary to U.S. and European evidence, the MAX effect in China does not weaken much less reverse the anomalous idiosyncratic volatility (IV) effect. Both the MAX and IV effects appear to independently coexist in the Chinese stock markets. Interpreted together with the strong evidence of risk-seeking behaviour among Chinese investors, our results partially support the suggestion that the negative MAX effect is driven by investor preference for stocks with lottery-like features.     

Audit Firm Tenure and Audit Quality in a Constrained Market

We examine the relation between audit quality and audit firm tenure in the Iranian audit market, which is constrained by government policies that create intense competition for clients among many small audit firms. We develop arguments that these circumstances create cost pressures that entrench low audit quality and render auditors' plans more predictable to managers wishing to misstate their accounts. Using publicly available data for the audits of listed companies in Iran prior to mandatory audit firm rotation and the incidence of misstated financial reports identified by the Iranian Association of Certified Public Accountants Inspection Office, we find that the likelihood of a misstatement is lowest in the first two years of audit firm tenure. We also find that the likelihood of misstatement is not associated with the year preceding a mandatory audit firm rotation, suggesting outgoing auditor effort is not sensitive to the prospect of subsequent revelations of deficiencies. Although our results from a pre-mandatory rotation period show that frequent rotations appear to improve the financial reporting quality in our sample, we are wary of interpreting these results as support for the mandatory audit firm rotation policy in Iran. Rather, we suggest this is a peculiar consequence of deficiencies in audit quality inherent in the Iranian market.     

Auditor specialization, perceived audit quality, and audit fees in the local government audit market

Prior governmental research implies a positive relation between auditor specialization and audit quality, but the effect of specialization on audit fees is mixed. However, no single governmental study investigates the effect of auditor specialization on both audit quality and audit fees. Also, prior studies focus on either large- or small audit firms and often employ indirect proxies for audit quality. We study the effects of auditor specialization on perceived audit quality and audit fees. Our data represent both Big 5 and smaller audit firms and include three market-based measures of specialization. We survey 241 Florida local government finance directors and find that specialization is positively associated with perceived audit quality but not with audit fees. We also find that Big 5 auditors, often used as a proxy for higher audit quality in prior research, are not uniformly associated with increased perceived audit quality but consistently charge higher audit fees. Our results confirm a relation between measures of audit firm specialization and audit quality and raise questions regarding audit firm size and audit quality in the municipal sector. Our findings suggest that engaging specialized auditors may be good policy for many local governments.     

How individual auditor characteristics impact the likelihood of audit failure: Evidence from China

Audit failure imposes a severe loss on investors and damages market participants' confidence in financial reporting quality. This study investigates the impacts of individual auditor characteristics on the likelihood of audit failure. Chinese regulators mandate listed firms to disclose the engagement auditors' identity. Furthermore, the information regarding individual auditor characteristics in China is also publicly available. Utilizing this unique setting, we examine the relationship between individual auditor characteristics and the likelihood of audit failure in China during the period from 2000 to 2009. We document that individual auditors with more auditing experience are less likely associated with audit failure. We also find a weaker negative relationship between auditor education level and audit failure. Our study has important implications for both auditors and regulators by shedding lights on the determinants of audit failure and by providing guidance to the human resource management in audit firms.     

The effect of small audit firms’ failure to remediate the PCAOB’s quality control criticisms on audit market segmentation

This paper examines the role of the Public Company Accounting Oversight Board (PCAOB) quality control inspection program on market segmentation of small firms’ audit services. Specifically, we investigate how non-remediation of quality control criticisms (QCCs) affects the supply and demand of low-quality audits. We find that remediation of QCCs improves audit quality for small accounting firms. However, some small accounting firms do not remediate QCCs (NR firms) and continue to provide low audit quality. We investigate how NR clients react to the disclosure of non-remediation of QCCs. We find that NR clients with low agency costs are more likely to retain NR firms after the disclosure of non-remediation. This finding is consistent with our expectation that voluntary QCC remediation creates a low-quality audit market segment for NR firms. Our findings suggest that the public disclosure of QCCs is not sufficient to remove low-quality auditors. Instead, NR clients use the disclosure of non-remediation of QCCs as a signal to sort themselves into segments based on their demand for audit quality. We are the first to study and find that PCAOB inspections, and specifically the voluntary nature of remediation and public disclosure of lack of remediation, create market segmentation.     

Auditor rotation and the appearance of independence: Evidence from non-professional investors

We examine the impact of audit firm versus partner rotation on non-professional investors’ independence-related perceptions, extending prior research on auditor rotation and independence in fact. Arguments for mandatory audit firm rotation continue to be made by regulators and investor groups based, in part, on the idea that firm rotation will incrementally strengthen independence in appearance relative to audit partner rotation. We report the results of two experiments. The first examines 5-year audit firm versus partner rotation under relatively weak or strong audit committees. We find no statistically significant difference in beliefs about how much of an income reducing audit difference management will record, or in beliefs about auditor independence, between the two auditor rotation conditions. On the other hand, we find that non-professional investors do believe more of the audit difference will be recorded, and the auditors will be more independent, under a strong audit committee than a relatively weak audit committee. The second experiment provides further evidence on audit firm versus partner rotation by examining a setting involving a 26-year audit firm–client relationship. Again, no statistically significant differences between the two auditor rotation conditions were found. These findings suggest that compared to audit partner rotation, audit firm rotation does not strengthen independence in appearance among non-professional investors and that non-professional investors recognize the value of strong audit committees.
