Abstract

“Crowdsourcing” is the sourcing of organizational functions from the “crowd”: a large, undefined community of a firm’s consumers, partners, and collaborators. A crucial challenge in crowdsourcing is to determine the quality of crowdsourced submissions. To help screen submissions, crowdsourcing portals use crowdvoting: they ask the community to vote on submissions. Our study investigates the informational role of crowdvoting on design submissions on Threadless, a pioneering crowdsourcing website. We collect and examine a novel, large scale dataset tracking over 150,000 designs, submitted by over 45,000 designers, voted on almost 150 million times, by over 600,000 different users. We focus on two questions. First, what is the conventional wisdom—how does crowdvoting influence Threadless? Second, does the conventional wisdom stand up to scrutiny—does crowdvoting systematically predict commercial success? We document several new empirical findings relating crowdvoting to revenues. We conclude by discussing the implications of our research for designers and firms seeking to ride the crowdsourcing tide.

Séminaire HEC/ESSEC - Localization of Global Accounting Practices: A comparative analysis of practice variation in response to institutional complexity

We conduct a comparative analysis of the initial stages of implementation of global accounting and control practices in two member organizations of an international network. We analyze organizational responses to institutional pressures. We attend to nested institutional levels and show how institutional logics, enacted by executives in early stages of implementation, mediate variations in the localized accounting and control practices. Our study contributes to understanding how field level pressures shape practice variation beyond loose coupling and decoupling. We also highlight the importance of early stages of localization of accounting practices, given the path dependent nature of institutions. Executive team decisions and actions in response to field level pressures in the early stages of localization shape organizational responses to the introduction of global accounting practices. We find that localized accounting and control practices are institutional hybrids and we propose a process that explains the source of variations in these accounting hybrids.

R Share Repurchases and Accounting Conservatism

The prior literature indicates that financial policy (e.g., payout policy) as well as accounting policy (e.g., conservatism) can be used to address incentive problems in firms. Similar to findings in Louis and Urcan (2014) who study cash dividends, we find that stock repurchases, an increasingly popular form of payout, are negatively related to conservatism, suggesting that these mechanisms are substitutes. Extending this analysis, and focusing on a particular manifestation of the incentive problem (managerial propensity to engage in overinvestment using free cash flows), we find that in firms with high levels of free cash flows, the negative relation between share repurchase and conservatism is stronger. By contrast, we find that the substitution effect is weaker when CEO tenure is higher, which confirms that more powerful CEOs have less incentives to solve the overinvestment problem. In an ancillary test, we show that the stock market reaction to share repurchases is increasing in conservatism, suggesting that the relation between conservatism and repurchases is complex (i.e., with multiple dimensions).

Performance Isn’t Everything: Personal Characteristics and Career Outcomes of Mutual Fund Managers

We find that mutual fund managers’ career outcomes are largely determined by past performance, measured by returns and fund flows. However, managers’ personal attributes also factor in. All else equal, female managers are less likely to be promoted and have shorter tenures than male fund managers. This finding largely applies to women who co-manage funds with other managers, which suggests that working in teams negatively affects women’s careers compared to men’s. Restricting the sample of managers to those that co-manage the same fund and have identical track records, we provide further evidence that female managers are significantly more likely to leave the job than male managers. After controlling for workload and performance, we show that young managers are more likely to be promoted and less likely to be demoted or fired than their older peers.

Re-forming healthcare: The role of accounting artifacts

Comptabilité et Contrôle de Gestion

Intervenant : Jeff Everett
York University

2 juin 2017 - HEC Paris - salle T004 - De 14h00 à 16h00


This study examines the role accounting plays in major healthcare-policy-reform processes.
Focusing on a single hospital site in the African nation of Ghana, and starting from the practice theory of Pierre Bourdieu, the study analyzes how different forms, constructions, and classifications of accounting information—or accounting artifacts—shape policy regimes and facilitate particular patterns of activity and interaction. It further examines how these regimes and patterns, in conjunction with the embedded social memory or habitus of individual actors, in turn lead to the construction and use of new artifacts. The study also highlights how hospital staff and patients use various tactics to work with and around these artifacts, resulting in at times unintended consequences and the need to pursue new policy directions. In so doing, the study furthers our understanding of why policy-reform processes in the field of healthcare are so often sequential in nature.
