Encouraging Professional Skepticism in the Industry Specialization Era

This paper provides theory and experimental evidence that, under common audit conditions, industry specialization inhibits some aspects of auditors’ professional skepticism. As auditors amass industry experience, they develop extensive knowledge of non-misstatement explanations for unusual financial statement fluctuations. This knowledge coupled with confidence in their ability to analyze audit evidence inhibits their inclination to be skeptical when there are no overt indicators of elevated misstatement risk. Although these conditions are, by definition, the conditions where misstatements are least likely, they are also the same conditions where the PCAOB has alleged pervasive insufficient professional skepticism and where well-concealed fraud is possible. These results pose an ethical dilemma for the PCAOB in terms of weighing its charge to protect the public interest against the fairness of its inspections to audit firms. Encouragingly, I also predict and find that audit firm efforts to promote professional skepticism are more effective for specialists as non-specialists are skeptical regardless of these efforts.     

Disentangling location-based advertising: the effects of location congruency and medium type on consumers' ad attention and brand choice

Research on location-based advertising (LBA) suggests that the merits of LBA lie in the fact that consumers can be targeted with location-congruent ads on their personal mobile devices. However, LBA consists of two underlying constructs: a mobile (vs. point-of-sales) advertising medium and location congruency (vs. location incongruency). This study aims to disentangle these underlying constructs by showing that they differentially affect the efficacy of an ad. Using a virtual reality lab experiment, this study shows that location-congruent ads result in increased choice for the target brand as compared to location-incongruent ads, independent of medium type. However, in location-incongruent situations, mobile ads attracted more attention than point-of-sales display ads. The advantages of LBA thus do not seem to emanate from medium type, but rather from the congruency between the ad and product location. When the ad is received at a different location than the product, the mobile medium is able to enhance consumers' ad attention.

Signalling,Disclosure And The Implications Of Financial Structure For Uk Corporate R&D ∗

This paper investigates the impact of R&D disclosure and finance variables on the level of R&D expenditures. The question addressed is: what is the impact of changes in disclosure requirements on the relationship between R&D expenditure and the financing of firms? The question is motivated by the possible signalling role that elective disclosure may have had prior to changes in accounting practices to ensure R&D disclosure.     

Birth,death and public good provision

We explore the effect of fixed versus dynamic group membership on public good provision. In a novel experimental design, we modify the traditional voluntary contribution mechanism (VCM) by periodically replacing old members of a group with new members over time. Under this dynamic, overlapping generations matching protocol we find that average contributions experience significantly less decay over time relative to a traditional VCM environment with fixed group membership and a common termination date. These findings suggest that the traditional pattern of contribution and decay seen in many public goods experiments may not accurately reflect behavior in groups with changing membership, as is the case in many real-world environments.     

An econometric model for ex ante prediction of wildfire suppression costs

This paper develops an econometric model that can provide predictions of fire suppression costs (per acre and in total) for a given large fire before final fire acreage is known. The model jointly estimates cost per acre and acreage equations via Maximum Likelihood, accounting for sample truncation based on final fire size. Formulas and results are shown for predictions of costs and fire size for wildfires in general, and for large fires in particular. Marginal effects of explanatory variables on cost and acreage are discussed. The distribution of these model predictions illustrates the importance of accounting for sample truncation when generating predicted outcomes based on ex ante information.     

Existence of a Pareto-optimal equilibrium in nearly-stationary overlapping-generations economies

Summary In overlapping-generations models of fiat money, the existence of a Pareto-optimal equilibrium — which defines an optimal quantity of money — is more general than well-known counter-examples suggest. Those examples, having no optimal equilibrium just because there are small variations in households' tastes and endowments across generations, are not typical. On the contrary: For an open-dense, full-measure subset of smooth stationary economies and an open-dense subset of continuous stationary economies, introducing small variations in tastes and endowments across generations preserves the existence of an optimal equilibrium. Put simply, optimal equilibria generically exist for nearly-stationary economies.I thank Scott Freeman, Katsuhiko Kawai, and two referees for proofreading this text; all lead to clarifications.     

Place in Entrepreneurial Storytelling: A Study of Cultural Entrepreneurship in a Deprived Context

We extend the cultural entrepreneurship perspective by investigating how entrepreneurs in deprived contexts gain legitimacy by leveraging proprietary and public places in their entrepreneurial storytelling. Inspired by the sociology of place, we present a longitudinal study of ten new venture journeys over four years in Kasoa, Ghana. We identify three distinct ways places are used in entrepreneurial narratives: projective significance of place, connective significance of place, and authoritative significance of place. We show how impoverished entrepreneurs construct and communicate places in diverse ways, not only as locations, but also as material and symbolic resources that provide legitimacy for their venturing activities. Drawing from our findings, we generate a model of place-based cultural entrepreneurship and elaborate place as a central resource in cultural entrepreneurship and new venture creation in deprived contexts.     

Measuring the dynamics of APEC output connectedness

We examine the dynamics of output connectedness of Asian Pacific Economic Cooperation (APEC) economies using time‐varying, region‐specific, generalised connectedness measures. We find that the connectedness of APEC economies with the rest of the world is quite substantial, with the 2008–09 Global Financial Crisis increasing the connectedness measures above their precrisis levels. The USA, China, and Korea are shown to be systemically important and to dominate APEC’s real activities, while outside the APEC region the roles of India and the UK are also non‐negligible. These results suggest that the majority of APEC economies are considerably open to output shocks from the dominant economies such that policymakers in APEC must be continuously conscious of headwinds originating from these sources.
