Timely Cybersecurity Disclosure and Information Manipulation
Timely Cybersecurity Disclosure and Information Manipulation
Regulators have increasingly mandated firms to promptly disclose material cybersecurity incidents upon discovering these incidents. We find suggestive evidence indicating that some firms manipulate the discovery date (“misreport”) of a cybersecurity incident to postpone the disclosure of the incident, as evidenced by a pronounced spike in insider sales before the reported discovery date. We also find that misreporting is more prevalent among firms with weak internal control systems, when firms face low litigation risk, and when firms have greater pressure to meet a disclosure deadline. Further, firms suspected of misreporting tend to disclose their remedial actions and assert the restoration of business, mitigating negative market reactions upon disclosure of incidents. Collectively, our results suggest that firms might strategically misreport information about a cybersecurity incident to delay disclosure to gain additional time for remedial actions, which helps them prevent exposing vulnerabilities to malicious actors and alleviate stakeholder anxiety.

Beyond Money: Incentive Effects of Tokenized Ownership on User Contribution in DAOs
Beyond Money: Incentive Effects of Tokenized Ownership on User Contribution in DAOs
Blockchain technologies have catalyzed the rise of decentralized autonomous organizations (DAOs), which operate in an incentive network fueled by crypto tokens. In essence, these tokens are imbued with either payment rights (i.e., transactional tokens) or ownership rights (i.e., governance tokens). The decentralized organizational paradigm dismantles the traditional management structure and bring new research opportunities to Operations Management (OM). While the performance of DAOs has been largely examined in current OM literature, the effectiveness of their internal incentive mechanisms—specifically the one that uses ownership as rewards to promote user contributions—remains unclear. Focusing on DAO-enabled virtual communities, we seek to examine whether decentralized ownership provides stronger incentives for user behaviors, such as creation and curation, in comparison to traditional monetary rewards through the lens of psychological ownership theory. We obtained data from Steemit that captures the reward, creation, curation and transaction behaviors of 98,000 users from May 2017 to April 2019. By leveraging the “power-up” action as a shock that increases user ownership shares, we established a quasi-experimental setting. Employing the PSM-DID model, we found that the use of governance tokens is associated with enhanced creation and curation efforts but declined creation novelty, compared to the use of transactional tokens. Our additional analyses further reveal that the incentive effects of governance tokens diminish over time. However, upon the recurrence of the intended choice, these effects become reinforced. Notably, we find that governance token ownership is more strongly associated with curation efforts for users with weaker social ties. Conversely, for users with high reputation scores, their content creation behaviors are less strongly associated with governance token ownership. This study contributes to the burgeoning discourse on blockchain and cryptocurrency from an operational perspective, providing valuable insights for the design of incentive mechanisms in DAOs and advancing our understanding of operational efficiencies and stakeholder engagement in decentralized structures within Operations Management.

The Impact of “Lazy Minting” on Seller Performance in NFT Marketplaces—A Transaction Cost Economics Perspective
The Impact of “Lazy Minting” on Seller Performance in NFT Marketplaces—A Transaction Cost Economics Perspective
In the burgeoning marketplaces of digital assets, non-fungible tokens (NFTs) revolutionize digital asset ownership and intellectual property (IP) protection, but high minting costs create barriers to marketplace entry and growth. This study examines the impact of “lazy minting,” a new NFT production method introduced by major NFT marketplaces to lower minting costs by deferring blockchain certification until the first sale. In response to the call for further research on emerging technologies in operations management, we explore how this policy affects the net sales performance of existing sellers in the NFT marketplaces. Based on transaction cost economics (TCE) and the literature about different IP protection methods, we distinguish between lazy- and regular-minted NFTs by their differential transaction costs and utilize the staggered difference-in-differences (DID) method to conduct our analysis. We find that lazy minting adoption significantly boosts the net sales performance of existing sellers. This is attributed to their cost-adaptive IP protection behavior. Specifically, they achieve this by minting more NFTs with a larger proportion of style-consistent NFTs through lazy minting, while strategically employing regular minting for style-breaking NFTs, which is contingent upon their reputation. Our study has important theoretical and practical implications for operations management under the emerging technological revolution.

Corporate Lobbying of Bureaucrats
Corporate Lobbying of Bureaucrats
Executive agencies play a pivotal role in shaping the regulatory environment by crafting rules, enforcing regulations, and overseeing government contracts—all of which can have a profound impact on businesses. For firms, this potential impact creates a clear incentive for firms to influence these agencies, particularly during the critical stages of rulemaking and enforcement. In this context, lobbying emerges as a key tool that companies use to mold the regulatory landscape to their advantage. Unlike politicians, whose decisions are often swayed by electoral cycles and campaign contributions, agency officials are not elected, serve longer terms, and are less susceptible to direct political pressures. As a result, engaging in lobbying efforts with executive agencies is both more complicated and strategically crucial for firms operating within heavily regulated industries. However, the dynamics of such lobbying remain underexplored in the literature.

How to Recover from Work Stress, According to Science
How to Recover from Work Stress, According to Science
To combat stress and burnout, employers are increasingly offering benefits like virtual mental health support, spontaneous days or even weeks off, meeting-free days, and flexible work scheduling. Despite these efforts and the increasing number of employees buying into the importance of wellness, the effort is lost if you don’t actually recover. So, if you feel like you’re burning out, what works when it comes to recovering from stress? The authors discuss the “recovery paradox” — that when our bodies and minds need to recover and reset the most, we’re the least likely and able to do something about it — and present five research-backed strategies for recovering from stress at work.

彼此不再依賴的世界? AI與自動化如何重塑世界貿易格局
自動化和人工智慧(AI)正在顛覆傳統國際貿易格局,讓發達國家在原本低技能勞動力密集型產業中獲得內生比較優勢,從而逆轉發展中國家的傳統優勢。 根據2025年最新趨勢,這一變化已加速全球供應鏈重構,並加劇了貿易不平等。
香港網約車的前世今生
香港網約車的前世今生
在香港這座人口密集的國際大都市,街頭流動的紅、綠、藍色計程車曾是城市活力的象徵。 然而,近年來,的士服務質素參差不齊、司機老齡化、拒載繞路頻發等問題日益凸顯,促使社會重新審視傳統出行模式的可持續性。 2025年10月,隨著《道路交通(修訂)(網約車服務)條例》正式刊憲,香港交通運輸生態迎來了歷史性轉折:網約車服務於2014年通過Uber等平臺進入香港市場,11年後終於獲得了合法地位,標誌著這座城市正式邁入的士與網約車共存互補的新時代。
