Structural drivers of upstream supply chain complexity and the frequency of supply chain disruptions

A great deal of research has focused on supply chain risk management, but the question “Which supply chain characteristics increase the frequency of supply chain disruptions?” has not received much attention from empirical research. This is a relevant question, because firms seek stability in their operations, and therefore managers need to know how the structure of their supply chains affects the occurrence of disruptions. The present study addresses this issue with a specific focus on upstream supply chain (supply-side) disruptions. Drawing on the literature on supply chain complexity, we devise and test a model that predicts the frequency of supply chain disruptions based on a multi-dimensional conceptualization of upstream supply chain complexity. Not only do the empirical findings suggest that all of the three investigated complexity drivers – horizontal, vertical, and spatial complexity – increase the frequency of disruptions, but also that they interact and amplify each other's effects in a synergistic fashion.     

On the differential market reaction to dividend initiations

The finance literature documents substantial positive stock price reaction to dividend initiations. Most dividend initiation studies focus on the average positive reaction; however, 40 percent of the firms that initiate dividends experience negative abnormal returns at announcement. This paper focuses on the apparent heterogeneity in the stock price reaction to dividend initiation. I find that the observed negative market reaction reflects the market’s economic assessment of the impact of the event on these firms, and that it is not caused by anticipation or confounding events. The result is also supported by the fact that the market reaction to dividend initiation for these firms is negatively related to initial dividend yield. Both the positive and negative observed reactions are consistent with conventional arguments regarding the information content of dividends, and their role in mitigating agency problems.     

Should we worry about the decline of the public corporation? A brief survey of the economics and external effects of the stock market

In recent years, the number of listed companies has been declining in many countries across the world. This paper provides a selective survey of the literature on the real economic effects of the stock market to assess the potential effects of this decline and determine whether it is likely to continue. The leading economic role of the stock market’s primary market, in which firms raise capital by issuing new shares, is to help growing firms secure financing. We discuss providing and certifying information, coordinating investors, and easing the redeployment of capital as the means through which capital allocation can be efficiently achieved. The main economic roles of the stock market’s secondary market, the trade in existing shares, is to provide liquidity to shareholders, to aid in price discovery and to provide diversification opportunities. Positive external effects from an active stock market may arise for consumers, labor and private firms due to increased corporate investment, more socially responsible business strategies and a more positive business climate. Negative external effects on capital allocation and productivity can arise from short-termism, market mispricing, and increased cross-ownership. Local stock markets can spur innovation and foreign direct investment (FDI) and reduce the risk of early cross-border acquisitions. Given the myriad of useful economic functions the stock market performs, a future entirely absent of public companies is difficult to imagine and the decline is therefore likely at some point to come to an end. Whether we need to worry about the decline depends on the relative importance of the positive and negative external effects, a topic we feel warrants more research.     

Spillover effects within supply chains: Evidence from Chinese-listed firms

There is increasing attention on information transfers along supply chain partners for firm (extreme) events. This growing literature finds spillover effects following certain types of firm events. Using data from credit rating actions of Chinese-listed firms over the period between March 2007 and May 2020, we examine the spillover effects of supply chains by focusing on the market reactions of event firms to the action announcements. We find strong evidence of spillover effects driven by the market reactions of event firms, which are enhanced through information diffusion channels as supply chain partners receive more investor attention. Moreover, the effects are stronger when event firms' market reactions are negative, event firms are non-stated-owned, the industry concentration of event firms is higher, or the supplier-customer business relationship is closer. Overall, these findings highlight the role of investor attention and network characteristics in supply chain spillovers.     

The Multijurisdictional Disclosure System and Value of Equity Offerings

The Canada and US multijurisdictional disclosure system (MJDS) implemented in 1991 lowered the indirect barriers for investors and issuers by easing reporting and disclosure requirements for cross‐border issues. This paper examines the impact of the MJDS and related regulatory changes on Canada–US equity market segmentation using a sample of Canadian seasoned equity offerings in the 1991–1998 period. We find that the number of cross‐border issues by Canadian firms increased, and the typical negative stock price reaction that accompanies seasoned equity issues declined over time, supporting increased integration between the two markets after the MJDS. We also document that cross‐border issues experience about 1.4 per cent lower negative stock price reaction compared with domestic issues, consistent with Canada–US market segmentation. We find mixed support for Merton's (1987) investor recognition hypothesis. While Canadian firms cross‐listed in the US experience a less adverse price reaction to their cross‐border offerings compared with their non‐US‐listed peers, there is no significant difference between the two groups in the case of purely domestic issues.     

Industries' heterogeneous reactions during the COVID-19 outbreak: Evidence from Chinese stock markets

This study examines the heterogeneous effects of the COVID-19 outbreak on stock prices in China. We confirm what is already known, that the pandemic has had a significant negative impact on stock market returns. Additionally, we find, this effect is heterogeneous across industries. Second, fear sentiment can directly cause stock prices to fall and panic exacerbates the negative impact of the pandemic on stock returns. Third, and most importantly, we demonstrate the underlying mechanisms of four firm characteristics and find that those with high asset intensity, low labor intensity, high inventory-to-revenue ratio, and small market value are more negatively affected than others. For labor-intensive state-owned firms, in particular, stock performance worsened because of higher idle labor costs. Finally, we created an index to measure the relative position of an industry in the supply chain, which shows that downstream companies were more vulnerable to the effects of the pandemic.     

The role of the seller’s stock performance in the market reaction to divestiture announcements

Divestitures have the potential to create shareholder value. However, the extent of the market reaction should depend on the likelihood of finding more valuable uses for the divested assets or the ability on the part of the seller to eliminate negative synergies. We hypothesize that strong performers have less scope to achieve substantial improvements compared to poorly performing firms. Using the seller’s stock return in excess of the market return in the 1-year and 2-year periods preceding the divestiture announcement to expose the divesting firm’s inefficient use of its assets, we show that the market reaction to divestiture announcements is significantly higher for underperforming firms. The difference in abnormal returns can be as high as 4 %. In contrast, none of the accounting-based variables that have been used in previous studies are found to be significantly related to the announcement returns. These results suggest that the firm’s stock performance is a more useful indicator of the wealth effect associated with divestitures.     

The changing relationship between job loss announcements and stock prices: 1970–1999

We study the reaction of stock prices to announcements of reductions in force (RIFs) using a sample of 4273 such announcements in 1160 large firms during the 1970–99 period collected from the Wall Street Journal. We note that the total number of actual announcements for the firms in our sample follows the business cycle quite closely. We then examine changes over time in standard summary statistics (means, medians, fraction positive) of the distribution of stock market reactions, measured by the cumulative excess returns (CER) of firms' stock prices over a 3-day event window centered on the announcement date, as well as changes over time in kernel density estimates of this distribution. We find clear evidence that the distribution of stock market reactions shifted to the right (became less negative) over time. One possible explanation for this change is that, over the last three decades, RIFs designed to improve efficiency have become more common relative to RIFs designed to cope with reductions in product demand. We estimate multivariate regression models of the CER controlling for the stated reason for the announced layoff, industry, and other characteristics of the announced layoff. We find that almost none of the decline in the negative average stock price reaction between the 1970s and 1990s can be explained by these factors.

Firm's resilience to supply chain disruptions: Scale development and empirical examination

This paper expands our understanding of factors that contribute to development of firm resilience to supply chain disruptions. In doing so, we operationalize firm resilience to understand how supply chain disruption orientated firms can develop resilience to supply chain disruptions. We find that supply chain disruption orientation alone is not enough for a firm to develop resilience. Supply chain disruption oriented firms require the ability to reconfigure resources or have a risk management resource infrastructure to develop resilience. The way in which supply chain disruption oriented firms develop resilience through resource reconfiguration or risk management infrastructure depends on the context of the disruption as high impact or low impact. In a high impact disruption context, resource reconfiguration fully mediates the relationship between supply chain disruption orientation and firm resilience. In a low impact disruption context, supply chain disruption orientation and risk management infrastructure have a synergistic effect on developing firm resilience.     

Supply chain integration and shareholder value: Evidence from consortium based industry exchanges

Recent trade and academic literature point to the importance of supply chain integration among partners as a key determinant of value creation. This paper analyzes the shareholder value effects of setting up industry exchanges, a prominent mechanism used to achieve supply chain integration. Shareholder value effects are estimated by measuring the stock market reaction (abnormal returns) associated with announcements to form or join industry exchanges. We find that abnormal returns from participation in industry exchanges are positive but only marginally significant in the whole sample of 144 firms in 18 exchanges formed during 2000–2001. In the sub-sample of 88 exchange founders who were part of the original announcements to form the exchange, the abnormal market reaction is about 1% and significant. We also find that firms with greater bargaining power and higher process efficiency benefit more from participation in industry exchanges.     

Risk reporting and stock return in the UK: Does market competition Matter?

This study examines the extent to which market competition influences risk reporting practice. It also explores how market competition affects the usefulness of risk reporting. The automated textual analysis measures the level of risk reporting [how much to report] and its tone [how it is reported] of UK FTSE 350 firms. The abnormal stock return is used as a proxy for the usefulness of risk reporting. In contrast to the proprietary cost hypothesis, our results indicate that the level of risk reporting is a positive function of market competition. Besides, UK firms are likely to disseminate more (less) negative (positive) news about their risks when market competition increases. However, after examining the informativeness of this reporting, we provide evidence that the level of reported risk information does not significantly enhance the abnormal stock returns of UK firms. Nevertheless, the tone of the reported risks carries incremental information indicative of a firm’s abnormal stock return, especially when market competition decreases. The findings suggest that firms are likely to alleviate their proprietary costs by framing their reporting of risk information in a way that deters potential competitors from entering their market and that market competition diminishes the perceived informativeness of such reporting. The results provide implications for investors as they should not acknowledge the disclosure of higher risk information when asking for more corporate transparency, as it lacks informativeness. Besides, policymakers may impose extra compulsory requirements on the UK firms to avoid reporting overly optimistic risk news to protect investors and avoid the adverse effects of this reporting.     

Market effects of private equity placement: Evidence from Chinese equity and bond markets

Research has provided empirical evidence for the stock market reaction toward private placement; however, similar research has not been conducted in terms of the bond market. Using the event study method, we empirically examine the explanatory power of the signaling, free cash flow, and wealth transfer hypotheses based on the reaction of the stock market, bond market, and firm abnormal returns to the private placement announcement. The results show that the stock market has a negative reaction toward private placement, whereas the bond market has a positive reaction. The results also show that the scale of private placement is correlated with the severity of the market reaction. Abnormal returns indicate no significant change both before and after the private placement, and they are unaffected by the scale of private placement. These results are consistent with the wealth transfer hypothesis; however, the market reaction is not attributable to the signaling hypothesis and the free cash flow hypothesis. Extensive research shows that the abnormal returns of private placement change dramatically in non-state-owned enterprises and firms with low credit rating bonds, whereas the bond maturity has no significant impact on the abnormal returns—the wealth transfer effect of private placement is stronger in non-state-owned enterprises and firms with low credit rating bond.     

Analysis of the effects of settlement of interfirm lawsuits

This study examines the effects of news on settlement of interfirm lawsuits. We hypothesize that the defendant firms suffer damaged reputation as news on the interfirm lawsuit remains in the ‘public eye’, as such ending the litigation process through settlement is good news for the defendant firms. Thus, the stock market will react positively to the defendants when news of a settlement is announced. On the other hand, settlements end the free publicity that the plaintiffs enjoy. In addition the plaintiffs settle for less money than they initially seek. Thus, the implication of a reduced cash flow expectations that the announcement of settlements brings to the plaintiffs will cancel out the positive reputation effect. Therefore, there will be no significant stock market reaction to the plaintiffs when a settlement is announced. Furthermore, the stock market will show no significant reaction to the defendants who have been the subject of more than one lawsuit in a relatively short period of time prior to a settlement because their reputation is too severely damaged to be remedied through removal of their name from the limelight. The results of our analysis support the hypotheses and offer some insight for strategy development. Copyright © 2006 John Wiley & Sons, Ltd.     

Sustainable development and environmental policy: The engagement of stakeholders in green products in Vietnam

Facing the challenge of environmental degradation in Vietnam, a growing number of firms have begun to integrate environmental management systems into their business strategies and develop green product diversification strategies. On the basis of the stakeholder theory, this paper attempts to explore the influences of stakeholders on the implementation of horizontal and vertical green product diversification. Empirical results show that foreign customers play a significant role in driving companies to adopt strategy of green product diversification. For foreign‐invested enterprises, the effect is limited to the adoption of horizontal green product diversification. It further reveals that institutional weakness, lack of transparency, community stakeholders, and regulatory stakeholders have no significant effect on the corporate green product strategy.     

Mandated Recognition of Employee Stock Option Expense – The Case of Canada

On December 18, 2003 the Accounting Standards Board of Canada announced that all firms registered in Canada would be required to expense stock options‐based compensation effective January 1, 2004. While a few firms had voluntarily opted to expense stock options prior to this date, the vast majority of firms had not. This study investigates the market reaction to this announcement by listed firms in the Toronto Stock Exchange that continued to disclose option expense rather than report it in the financial statement. We find no average market reaction by our sample firms affected by this mandate around the announcement date, but a significantly negative market reaction during the 5‐day window around the issuance date of the exposure draft. However, in cross‐sectional tests around the mandated expense announcement date, we find a significant negative relationship between the cumulative abnormal returns and the Black–Scholes value (and number) of options outstanding and of options granted the previous year. These results suggest that the magnitude of the market reaction to the mandated expense announcement is related to the firm's usage of options. Our results provide further evidence that stock prices may not fully impound information disclosed in footnotes.     

Reputation and Corporate Social Responsibility Aberrations,Trends, and Hypocrisy: Reactions to Firm Choices in the Stock Option Backdating Scandal

Drawing on strategic corporate social responsibility (CSR) and reputation theory, this paper examines the market reaction to firm disclosures of involvement in the US stock option backdating scandal. We examine how a firm's prior signals regarding ethical behaviour and values, as demonstrated through CSR initiatives, may both ameliorate and exacerbate market reactions. CSR initiatives may buffer a firm against general wrong‐doing but expose it to greater scrutiny and sanction for related wrong‐doing. Our results show that firms with enhanced overall reputations for CSR are partially buffered from scandal revelations. However, we find that when firms possess an enhanced reputation for CSR associated with corporate governance, violations pertaining specifically to governance are viewed as hypocritical and more harshly sanctioned. We also find lower and negative market reactions for firms that delay but self‐disclose their involvement in the scandal. The study extends the emergent, related literatures on strategic CSR and reputation management, and documents dynamics in the relationship between corporate social and financial performance.     

The impact of supply chain agility on business performance in a high level customization environment

To improve business performance in rapidly changing environments, supply chain agility can be a crucial requisite to address responsiveness issues, especially in environments with high levels of customization. This paper examines the effect of supply chain agility on customer service, differentiation, and business performance. A survey research methodology was employed using a sample of 156 manufacturing firms that provide high levels of customization. In particular, structural equation modeling (SEM) was employed to evaluate the proposed model. The results suggest that supply chain agility influences customer service and differentiation positively. However, it does not affect business performance directly; instead, better business performance can be achieved and mediated through improved customer service and differentiation. In particular, differentiation through customer service is the most effective way to improve business performance, and supply chain agility can help to achieve high-level customer service. The paper advises managers on details of how to fulfil their business performance ambitions better through suggested key agile supply chain management activities.     

Market Implications of the Audit Quality and Auditor Switches: Evidence from China

Independent audits enhance the credibility of corporate financial reports and assist investors to make rational decisions in the capital market. Nonetheless, the utility of the auditing function depends upon the quality of audits, which is determined by the independence and expertise of auditors. Hence, auditor choice and switch will not only affect an audit's quality, but will also influence decisions made by investors and other market participants. The purpose of this paper is to investigate how investors respond to the quality of audits and auditor switches in the Chinese context. Empirical results show that the quality of an audit and switching to a larger auditor have a positive (negative) impact on earnings response coefficients (ERCs) for firms with positive (negative) abnormal earnings. In contrast, switching to a smaller auditor has a negative (positive) impact on ERCs for firms with positive (negative) abnormal earnings. These results suggest that large auditing firms (Top 10) in China are perceived as more effective for curbing income-increased earnings management, which leads to higher (lower) ERCs for clients with positive (negative) abnormal earnings. Firms' switching to a larger auditor may signal high-quality earnings. Therefore, investors more often increase stock prices when firms have positive abnormal earnings and less often depreciate prices for negative abnormal earnings. Similarly, switching to a smaller auditor may signal lower earning quality, resulting in opposite market responses. In general, the empirical evidence suggests that audit information is valued by the capital market in China. Large auditing firms have been able to product-differentiate themselves within the Chinese stock market.
