Hidden in Plain Sight: Unpaid Household Services and the Politics of GDP Measurement

ABSTRACT

Gross domestic product (GDP) is one of the world’s most influential and widely cited economic indicators. However, outside of the industrialised, market-based context in which the indicator was first designed, GDP measurement suffers from a number of biases and blind spots. The article zooms in on one of these: the exclusion of unpaid household services from the production boundary of the System of National Accounts, the international standard underpinning GDP methodology. While GDP has expanded over time to include activities as diverse as financial services and the informal sector, the treatment of unpaid household services has remained unchanged. Why is this? I find that staff in the statistical departments of international organisations such the United Nations, International Monetary Fund and World Bank have a tremendous degree of agency in the governance of GDP. While these statisticians are aware of and engage with criticisms, they reject the inclusion of unpaid household services based on shared professional norms and economic ideas.     

The Role of Tacit Knowledge in Auditor Expertise and Human Capital Development

Two critical aspects of the model of auditor expertise development in Tan and Libby [1997] are that audit firms do not value tacit knowledge in inexperienced auditors but do value it in experienced auditors. We update the former and extend the latter. Our paper predicts and finds that audit firms now do value tacit knowledge in inexperienced auditors, especially when their supervisors have higher tacit knowledge. Our proxies of value include higher promotability assessments, annual evaluations, and cash bonuses. Our paper also extends Tan and Libby [1997] by positing that enhanced development of expertise and audit firm human capital are two reasons audit firms value tacit knowledge in experienced auditors. As predicted, higher tacit knowledge in experienced auditors is positively associated with higher tacit knowledge acquisition by their inexperienced subordinates and with stronger firm commitment of inexperienced subordinates having higher tacit knowledge.     

The impact of audit firms’ characteristics on audit fees following information security breaches

Given the importance of auditors’ assessing business risks and evaluating internal controls, we investigate whether an audit firm’s industry expertise, tenure, and size can help its auditors better understand external and internal threats faced by the client with less effort. Using reported information security breach incidents from 2004 to 2013, we find that, consistent with prior studies, audit fees are higher after the occurrence of an information security breach. However, such an association is negatively moderated when the audit firm has industry-specific expertise, longer experience with the client, and is one of the Big 4 firms. Our results suggest that because of their better knowledge about a specific industry, increased familiarity with the client’s operations, and more resources to understand a client’s vulnerabilities and/or information security policies and procedures, these auditors are more capable of assessing the potentially changing information security risks implied by the occurrence of information security breach incidents. Our results are robust to a variety of sensitivity checks.     

When Do Expert Teams Fail to Create Impactful Inventions?

We investigate the salience of expertise in creating high impact inventions and question experts’ ability to deploy novel ideas. Specifically, we examine the relationships between expertise, component originality, and a team's structural holes’ position in the collaborative network and propose that, in relative terms, expert teams create lower impact inventions if they deploy more original components and if they occupy structural holes. We test and confirm our hypotheses in a sample of semiconductor firms. In post‐hoc analyses, we find a three‐way interaction where the negative effect of structural holes almost disappears when an expert team experiments with original components whereas an increase in non‐redundancy is detrimental when teams with high expertise use familiar components. Our findings inform a foundational view of the invention process and provide novel insights into the contingent benefits of domain expertise.     

Tainted portfolios: How impairment accounting rules restrict security sales

Contrary to claims that fair value accounting exacerbated banks’ securities sales during the recent financial crisis, we present evidence that suggests – if anything – that the current impairment accounting rules served as a deterrent to selling. Specifically, because banks must provide evidence of their ‘intent and ability’ to hold securities with unrealized losses, there are strong incentives to reduce, rather than increase, security sales when market values decline to avoid ‘tainting’ their remaining securities portfolio. Validating this concern, we find that banks incur greater other‐than‐temporary impairment (OTTI) charges when they sell more securities. We then find that banks sell fewer securities when their security portfolios have larger unrealized losses (and thus larger potential impairment charges), and these results are concentrated in banks with homogenous securities portfolios, expert auditors, more experienced managers, and greater regulatory capital slack. Overall, our results suggest that – contrary to critics’ claims – the accounting rules appear to have reduced banks’ propensity to sell their securities during the financial crisis.     

How consumers’ assessments of the difficulty of manufacturing a product influence quality perceptions

This research shows that the perceived difficulty of manufacturing a product influences consumers’ perceptions of the firm’s other products. In three experiments (with 152 participants in Study 1, 86 in Study 2, and 91 in Study 3), participants received information about the quality of a firm’s product and then inferred the quality of another product from the firm. When participants believed that the initial product was relatively more difficult to manufacture than the second product, they inferred that the second product would be high in quality. However, when participants believed that the initial product was relatively easy to manufacture, they inferred that the second product would be low in quality. These effects occurred when perceived difficulty of manufacture was manipulated (Study 2) and occurred regardless of whether both products had dissimilar product benefits (Study 1) or whether brand names were present (Study 3).

Industry Expertise,Information Leakage and the Choice of M&A Advisors

This paper examines the impacts of M&A advisors’ industry expertise on firms’ choice of advisors in mergers and acquisitions. We show that an investment bank's expertise in merger parties’ industries increases its likelihood of being chosen as an advisor, especially when the acquisition is more complex, and when a firm in M&A has less information about the merger counterparty. However, due to the concerns about information leakage to industry rivals through M&A advisors, acquirers are reluctant to share advisors with rival firms in the same industry, and they are more likely to switch to new advisors if their former advisors have advisory relationship with their industry rivals. In addition, we document that advisors with more industry expertise earn higher advisory fees and increase the likelihood of deal completion.     

Managerial expertise,corporate decisions and firm value: Evidence from corporate refocusing

This paper investigates how managerial expertise—specifically, industry expertise—affects firm value through divestiture. Using CEOs’ managerial experiences in industries throughout their careers as a measure of their industry expertise, I find that CEOs in diversified conglomerates are more likely to divest divisions in industries in which they have less experience. This finding is consistent with CEOs who divest such divisions in order to refocus on those divisions in which they have specialized—that is, to achieve a better match between their expertise and their firms’ retained assets. Firms that divest for a better CEO-firm match experience significant improvements in operating performance, as well as significant abnormal stock returns that persist for an average of three years following a divestiture. Further, among firms that divest for a better match, those firms with more experienced CEOs realize greater gains in firm value. In contrast, divestitures that increase corporate focus, but do not improve the expertise-asset match, do not lead to long-run increases in firm value.
