The Effects of Audit Committee Ties and Industry Expertise on Investor Judgments

Despite regulations mandating audit committee independence, the CEO may still influence audit committee members’ objectivity through social ties (e.g., belonging to the same country club) or professional ties (e.g., having served on boards together). Further, research finds that audit committee industry expertise enhances financial reporting quality. In an experiment with 342 reasonably informed investor participants, we find that ties (professional or social) and industry expertise affect assessments of independence and competence. Further, investors assess audit committees with no ties and industry expertise (social ties and no industry expertise) as the most (least) effective and also result in the highest (lowest) likelihood of investing. Moreover, the potential negative effects of ties are attenuated by industry expertise, while the presence of no ties also appears to attenuate in part the lack of industry expertise. These findings support increased disclosures to investors of ties between management and members of the audit committee, as well as information on industry expertise.

Playing to Learn and Learning to Play: Effects of SuperstarApp Adoption on Enhancements to Mobile App Proficiency


Speaker: Sungho Park
Assistant Professor of Marketing , Arizona State University

6 June 2016 - Building T, Room T030 - From 1:30 pm to 3:00 pm

Despite the massive influx of mobile apps into the market, mobile users substantially differ with respect to their mobile app proficiency, i.e., the advent of mobile digital inequality. Using a dataset on individual mobile app usage, we examine the potential of highly ranked “superstar apps” as stimulants of consumption in terms of volume and extent, especially among less mobile-proficient users. We employ the Gaussian copula-based difference-in-differences framework given that it allows us to construct a flexible joint model of continuous app usage duration and discrete number of apps used. Results indicate that superstar adoption boosts app use variety and volume within the same app category and across different categories. Such spillover effects are more pronounced among less technically knowledgeable groups (e.g., users in their 50s or older and late adopters) and managerially under-represented target segments (e.g., irregular, occasional, and light app users). Use frequency and duration among superstar app adopters increase for newly downloaded apps but decrease for existing apps. We provide valuable implications that marketers can capitalize on to target low-proficiency users. We also recommend that policy makers can use superstar apps as nonintrusive and cost-efficient vehicles for enhancing mobile app proficiency and bridging the mobile digital inequality.

The Creative Destruction of Auditing Regulation

Accounting & Management Control

3 June 2016 - HEC Paris - Room T201 - From 2:00 am to 4:00 am

Despite increasingly transnational regulation, responses by national regulators to globalization and their implications on the forms of power and regulation underlying professional projects have still received limited attention (Faulconbridge & Muzio, 2011). Based on a longitudinal study covering the period 2003-2013, we examine the reactions of the French audit regulator (H3C) and the French audit industry to the ‘rescaling’ of their regulatory space from both a global and a local perspective. Overall, our findings highlight a performative process of ‘creative destruction’ (Schumpeter [1943], 2003) at work within the auditing regulation where globalizing pressures and firms’ entrepreneurial attitudes disrupt existing regulatory structures from within, while pushing the regulator and the profession to constantly redefine their positioning vis-à-vis global influences. Throughout this process, our analysis characterizes a chaotic dynamic of resistance and counter resistance where the H3C and the audit industry alternate opportunistically between internationalist aspirations and nationalist postures to maintain their spheres of influence. Even with their faith proclaimed in globalization and discourses aimed at discrediting their local regulation, audit firms remain infused with a significant ‘national character’ (Cooper et al., 1998) and don’t hesitate to forge circumstantial and powerful alliances with the H3C and various state actors aimed at domesticating transnational forces. From a broader viewpoint, we argue that the regulator’s resistance operates reciprocally with the power mobilized by the profession to defend its interests. Both are part of the same conditions of each other’s possibilities of action and prevent the emergence of a stable field of power, while facilitating the ongoing reconstruction of the local regulatory space.

A Model for Inferring Market Preferences from Online Retail Product Information Matrices


Speaker: Siddarth Sivaramakrishnan

This research extends information display board methods, currently employed to study information processing patterns in laboratory settings, to a field based setting that also yields managerially useful estimates of market preferences. A new model is proposed based on statistical, behavioral, and economic theories, which integrates three decisions consumers must make in this context: which product-attribute to inspect next, when to stop processing, and which, if any, product to purchase. Several theoretical options are considered on how to model product attribute selection and how to treat uninspected attributes. The modeling options are empirically tested employing datasets collected at a popular retail-manufacturer’s website, while customers were making product evaluation and purchase decisions. Subsequent to identifying the best model, we show how the resulting attribute preference estimates can be managerially employed to improve customer targeting of abandoned shopping carts, for follow up communications aimed at improving sales conversions.
