Firms should disclose information on material cyber-attacks. However, because managers have incentives to withhold negative information, and investors cannot discover most cyber-attacks independently, firms may underreport them. Using data on cyber-attacks that firms voluntarily disclosed, and those that were withheld and later discovered by sources outside the firm, we estimate the extent to which firms withhold information on cyber-attacks. We find withheld cyber-attacks are associated with a decline of approximately 3.6% in equity values in the month the attack is discovered, and disclosed attacks with a substantially lower decline of 0.7%. The evidence is consistent with managers not disclosing negative information below a certain threshold and withholding information on the more severe attacks. Using the market reactions to withheld and disclosed attacks, we estimate that managers disclose information on cyber-attacks when investors already suspect a high likelihood (40%) of an attack. 相似文献

The literature has mostly examined supply chain (SC) traceability and SC transparency separately, ignoring the mutually constitutive relationship of these two related constructs. We draw on the resource orchestration theory and the causal complexity perspective to conceptualize and validate SC traceability and SC transparency as interrelated organizational capabilities that may mutually enhance or compensate each other for competitive advantage. We constructed an original sample from two sources to empirically test this conceptualization using fuzzy set qualitative comparative analysis (fsQCA). Our empirical results reveal that the ability of firms to leverage SC traceability for a high financial performance is contingent upon creating a transparency perception of SC with a wide range of stakeholders. Our results also identified the firm size and its international presence, as having a significant bearing on the ability of firms to leverage SC traceability and SC transparency capabilities for a competitive advantage. 相似文献

Overwhelming evidence from prior research suggests a positive association between corporate board characteristics and carbon performance; however, very little is known about the mechanisms linking the two variables. This study attempts to fill this gap by developing and empirically testing a conceptual model that highlights the role of carbon strategy in the relationship between board environmental orientation (BEO) and carbon performance. We argue that BEO can directly and indirectly influence carbon performance through carbon strategy. Using structural equation modelling to analyse data consisting of 2,301 U.S. firm‐year observations over the 2005–2015 period, we find that the greater the BEO is, the better its carbon performance (i.e., lower greenhouse gas emissions). The results also provide evidence of the mediating effect of carbon strategy on the relationship between BEO and carbon performance. Splitting the sample into high and low carbon‐intensive industries shows a partial mediation effect in high carbon‐intensive industries and a full mediation effect in low carbon‐intensive industries. The findings of the study and its implications for scholars, policymakers, managers, investors, and environmentalists are discussed. 相似文献

Motivated by theoretical models in economics which show that there is matching between CEO skill and firm size, we introduce a new measure of director skill which is based on the aggregate size of firms on which the director serves as an independent director. We validate our measure by showing that it is positively associated with director experience, financial expertise, industry expertise and managerial experience. We then examine whether our average measure of skill across board members is positively associated with monitoring quality. Controlling for the endogenous relationships between board composition and financial reporting quality, we find a positive association between our board measure for skill and monitoring quality, and we show that directors have a causal impact on monitoring effort and outcomes. Furthermore, consistent with the enhanced monitoring provided by skilled directors, we document a positive association between the level of and changes in our measure and firm value. 相似文献

This study identifies how country differences on a key cultural dimension—egalitarianism—influence international investment flows. A society's cultural orientation toward egalitarianism is manifested by intolerance for abuses of market and political power and a desire for protecting less powerful actors. We show egalitarianism to be based on exogenous factors including social fractionalization, dominant religion circa 1900, and war experience from the 19th century. We find a robust influence of egalitarianism distance on cross-national flows of bond and equity issuances, syndicated loans, and mergers and acquisitions. An informal cultural institution largely determined a century or more ago, egalitarianism exercises its effect on international investment via an associated set of consistent contemporary policy choices. But even after controlling for these associated policy choices, egalitarianism continues to exercise a direct effect on cross-border investment flows, likely through its direct influence on managers' daily business conduct. 相似文献

This paper examines the size effect in the German stock market and intends to address several unanswered issues on this widely known anomaly. Unlike recent evidence of a reversal of the size anomaly this study documents a conditional relation between size and returns. I also detect strong momentum across size portfolios. The results indicate that the marginal effect of firm size on stock returns is conditional on the firm's past performance. I use an instrumental variable estimation to address Berk's critique of a simultaneity bias in prior studies on the small firm effect and to investigate the economic rationale behind firm size as an explanatory variable for the variation in stock returns. The analysis in this paper indicates that firm size captures firm characteristic components in stock returns and that this regularity cannot be explained by differences in systematic risk. 相似文献

We consider the standard two-stage game of R&D and Cournot competition with ex ante identical firms but depart from the literature in assuming that R&D is characterized by mildly, instead of strongly, decreasing returns to scale. We establish that only extreme R&D levels are possible at equilibrium, and that for a broad range of parameters, equilibria are asymmetric in R&D levels, possibly leading one firm to endogenously exit. This provides a simple link between returns to scale in R&D and industry polarization, including shake-outs. A novelty is that exit may be triggered by positive opportunities in a strategic setting. Given the original nature of our R&D equilibrium, a complete welfare analysis is conducted, including a possible role for R&D subsidies. 相似文献

Developing approaches for understanding customer perceived value is a priority for managers and scholars alike. A conceptual framework for assessment of value-in-use is proposed and explored within the context of a maintenance service provider. In contrast to value models in previous empirical research, the framework includes assessment not just of provider attributes but also of the customer's usage processes, as well as customer evaluations of the value-in-use they obtain. Interviews with members of a cross-disciplinary buying group provide support for the framework, including the observations that individuals can assess the quality of their usage processes and that they can articulate value-in-use at both organisational and individual levels; the further concept of network quality also emerges from the data. Assessment of usage process quality as well as service quality evolves as the customer's goals evolve. Practitioners may wish to elicit usage process quality and value-in-use as well as service quality. Research directions include scale development for both usage process quality and value-in-use. 相似文献

This study identifies Canadian fiscal and monetary policy regime changes that could influence the services of money. It is argued that if these policy regime changes were not incorporated in the estimation of demand for real balances, the resulting estimate would be biased and unstable. Using Canadian monthly data for the January 1975 to June 2001 period, the paper estimates a standard demand-for-money (M1) function with and without these policy regime changes. It was found the demand for money in Canada is stable over the short- and long-run periods when these policy regime changes are incorporated and the estimated coefficients have correct signs. 相似文献
