Factors that Influence the Learning Curve: Evidence from Cost Behavior in Clinical Labs*

Clinical labs belong to a mature industry and fulfill a critical function in the health-care value chain. We examine factors that influence the opportunity, motivation, and ability to learn in clinical labs. We hypothesize that with respect to learning about cost: (i) organizational design, such as the extent of outsourcing can impede the opportunity to learn, (ii) quality focus (measured by mortality rates and length of stay (LOS)) can reduce the motivation to learn, and (iii) related task variety (measured by product-mix breadth) and information technology investments can enhance the ability to learn. Our empirical tests calibrate learning effects on disaggregate (technical and supervisory hours and cost) and aggregate (salary and total direct cost) cost and time pools. Using longitudinal data from clinical labs in California for the period 1997–2015, we find that clinical labs with greater cumulative output have lower average costs, consistent with learning effects in clinical labs. We also find results consistent with our hypotheses about the contextual factors that influence learning rates in clinical labs. Our findings contribute to a better understanding of learning rates with implications for budgeting, forecasting, and performance measurement. The results highlight that learning can be a crucial source of cost reduction in health-care settings.     

An Empirical Analysis of Analysts' Capital Expenditure Forecasts: Evidence from Corporate Investment Efficiency*

We examine whether the information conveyed in a relatively new analyst research output—capital expenditure (capex) forecasts—affects corporate investment efficiency. We find that firms with analyst capex forecasts exhibit higher investment efficiency. This effect is stronger when the forecasts are issued by analysts with higher ability or greater industry knowledge. Moreover, the effect of capex forecasts on investment efficiency varies with the signals they convey about future growth opportunities—positive-growth signals are more effective in reducing underinvestment, while negative-growth signals are more effective in reducing overinvestment. Cross-sectional tests suggest that these effects operate at least in part through both a financing channel and a monitoring channel. Taken together, our results suggest that analysts' capex forecasts convey useful information about firms' growth opportunities to managers and investors, which can facilitate efficient investment.     

Endogeneity and the Dynamics of Voluntary Disclosure Quality: Is there Really an Effect on the Cost of Equity Capital?*

Research on the effects of voluntary disclosure quality on the cost of equity capital is often plagued by endogeneity concerns. In this paper, I use a dynamic panel system GMM estimator, which provides internal instruments from the firm's history that directly address endogeneity arising from unobserved heterogeneity and simultaneity. By using hand-collected voluntary disclosure scores for firms listed in the Swiss stock exchange, I examine the dynamic relation between voluntary disclosure quality and the cost of equity capital in a panel over a period of 10 years. The results suggest that the relation between voluntary disclosure quality and the cost of equity capital becomes insignificant after controlling adequately for potential dynamic endogeneity, simultaneity, and unobserved heterogeneity.     

A Simple Approach to Better Distinguish Real Earnings Manipulation from Strategy Changes*

Researchers typically infer real earnings management when a firm's operating and investing activities differ from industry norms. A significant problem with classifying deviations from industry averages as myopic earnings management is that companies can change their operating and investing decisions for strategic business reasons rather than to mislead stakeholders. Using principal components analysis, we systematically evaluate existing measures and develop a comprehensive real activities measure to better capture earnings manipulation. Our measure reflects (i) deviations from industry averages across multiple activities and (ii) other signals of manipulation. This approach is promising because, although there are many sources of abnormal activities, manipulation is more likely the cause when managers engage in multiple income-increasing abnormal activities that coincide with other signals that indicate an elevated risk of manipulation. This simple approach results in a metric that associates negatively with future operating performance and earnings persistence, yields high-power tests, and captures manipulation reasonably well across most life-cycle stages. Importantly, this approach performs better than the standard real earnings management metrics across all dimensions. Specifically, it generates the expected reduction in future earnings and reduced earnings persistence in 82% of the tests compared to 36% and 46% in common alternatives. Also, because this innovation does not require a long time-series or rely on future period realizations for classification, it can be useful in more research settings than other recent innovations in the literature.     

Foreign Holding Companies and the US Taxation of Foreign Earnings: Evidence from the Tax Increase Prevention and Reconciliation Act of 2005*

I analyze US multinationals' (MNCs) use of foreign holding companies in their organizational structures and the impact of holding companies on internal capital markets. The look-thru rule in the Tax Increase Prevention and Reconciliation Act of 2005 (TIPRA) reduces the after-tax cost of foreign intercompany financing transactions. I use TIPRA as a natural experimental setting to test whether a shift in US tax policy that reduces the cost of moving foreign capital increased firms' reliance on foreign holding company subsidiaries. I find that MNCs responded to TIPRA by creating more foreign holding companies. Furthermore, consistent with the policy objectives of TIPRA, I document that MNCs that rely on holding companies gained tax efficiencies in their post-TIPRA foreign internal capital markets, reducing domestic taxation on foreign earnings and easing financial constraints. Overall, my results expand our understanding of foreign organizational structure decisions and their internal financing benefits. I contribute to the tax literature by documenting a response to TIPRA that sheds light on the growing complexity of foreign subsidiary ownership structures.     

Auditors' Responses to Workload Imbalance and the Impact on Audit Quality*

Using detailed data for fieldwork hours and audit hours by rank from audit engagements in Korea, we examine whether audits conducted under workload imbalance, proxied by busy‐season audits, impair audit quality, and how auditors adjust staff assignments for busy‐season audits. We generally find that busy‐season audits are associated with lower audit quality, and that audit firms reduce the involvement of senior auditors during busy‐season audits. In addition, the greater the involvement of senior auditors and junior auditors, the lesser the deterioration in audit quality. Finally, although there is no increase in interim audits in response to workload imbalance during busy seasons, increasing interim audits can mitigate the negative impact of busy‐season audits on audit quality. Our results are relevant to auditors and regulators, who have expressed concerns about the adverse effects of workload imbalance on audit quality.     

股权资本成本与高管薪酬激励--一个高管薪酬改革思路的理论性阐释

以会计绩效为基准的高管薪酬制度是当今的主流，广泛应用于国际企业界。然而越来越多的研究证据表明，高管薪酬与会计业绩之间的关系不足以成为建立高管薪酬制度的理论基础。唯有遵循股东至上原则的高管薪酬方案才能既满足管理层对于薪酬的预期，又有助于在可持续发展的前提下，实现股东财富最大化目标。股权资本成本是这种高管薪酬制度设计的基本因素与核心参数。     

Trading Prior to the Disclosure of Material Information: Evidence from Regulation Fair Disclosure Form 8‐Ks*

Regulation Fair Disclosure (Reg FD) Form 8‐K filings provide a venue where managers release information to the market as a whole that they designate as being material. Using this setting, we study trading patterns immediately prior to the public disclosure of material information. We offer three main results. First, using both intraday and daily trading data, we find abnormal trading volume of 21 percent (13 percent) in the hour (day) prior to the public disclosure, respectively. Second, we find that this pre‐disclosure abnormal trading volume is concentrated in firms that are smaller, have more growth opportunities, issue fewer voluntary disclosures, and have weaker external monitoring. Finally, we find that this pre‐disclosure volume is concentrated in subsamples in which the information relates to a firm's material contracts, a firm holds investor/analyst conferences, and there is insider trading activity in a firm's shares. Our results do not concentrate in a small number of firms or industries, and do not appear to be explained by the form through which managers first release the material information (e.g., Form 8‐K, press release, website posting, or social media). Our results are also robust to controlling for the firm's other filings and peer filings that occur around the disclosure. Overall, the trading patterns we document may show that, inconsistent with the spirit of Reg FD, a subset of investors trade on information managers deem material prior to its broad, public release.     

PCAOB Inspections and the Differential Audit Quality Effect for Big 4 and Non–Big 4 US Auditors*

In this study, we investigate whether the increase in regulatory scrutiny epitomized by the initial PCAOB inspection impacted audit quality differentially for Big 4 and non–Big 4 auditors to better understand the consequences of PCAOB inspections for different audit firm types. Because of competing views on the effect of PCAOB inspections, the relation between PCAOB inspections and the audit quality differential between Big 4 and other auditors is an empirical issue. Empirically, we take the endogenous choice of auditor as a given and utilize a difference‐in‐differences specification that takes into account the staggered timing of the initial PCAOB inspection for different‐sized auditors in the United States. Our results suggest that the initial PCAOB inspection improved audit quality more for Big 4 auditors than for other annually inspected or triennially inspected non–Big 4 auditors. We also examine annually and triennially inspected non–Big 4 auditors separately, and find that the pre‐post Big 4/non–Big 4 differential audit quality effect is more pronounced for the triennially inspected non–Big 4 firms. In the larger context of the highly concentrated US audit market, our findings that PCAOB inspections accentuate the Big 4/non–Big 4 audit quality differential are of potential interest to public company audit clients contemplating an auditor change, investors interested in learning about the consequences of PCAOB inspections, regulators concerned about the Big 4 dominance of the US audit market, and academics investigating audit quality differences.     

Volatility of Tax Payments and Dividend Payouts*

Dividends are a key mechanism for shareholders to discipline managers and mitigate agency conflicts. This study examines whether the volatility of tax payments is associated with dividend payouts. Consistent with the predictions, results suggest that firms with more volatile tax payments are less likely to pay dividends overall and their dividends are lower in magnitude when doing so. These effects are economically significant and incremental to a firm's operating risk. The link between volatile tax payments and the likelihood of dividend payouts is weaker for firms that distribute dividends to alleviate agency conflicts. Similarly, the link between volatile tax payments and the amount of dividend payouts is weaker for firms that hold more cash for tax reasons. Taken together, these findings add to our understanding of the economic consequences of volatile tax payments and the determinants of dividend payouts.     

Incentive Contract Design and Employee-Initiated Innovation: Evidence from the Field*

This study examines how the design of incentive contracts for tasks defined as workers' official responsibilities (i.e., standard tasks) influences workers' propensity to engage in employee-initiated innovation (EII). EII corresponds to innovation activities that are not formally assigned to workers but are nonetheless encouraged and considered to be important for the company's success. Like other extra-role behaviors, EII is difficult to incentivize directly. Therefore, it is important to understand whether and how explicit incentive contracts designed for the workers' standard tasks may indirectly influence their EII activity. We use field data from a manufacturing company that uses a dedicated information system to track workers' EII idea submissions. We find theory-consistent evidence that, compared to workers receiving fixed pay, employees rewarded for their standard tasks with variable compensation contracts exhibit a lower propensity to engage in EII. This result is concentrated among ideas benefiting other constituents and activities beyond the proponents' standard task (i.e., broad-scope ideas). In contrast, we find no difference attributable to standard task incentive design in the proposal of innovation ideas narrowly focused on the proponent's standard task (i.e., narrow-scope ideas). Our findings suggest that variable pay narrows employees' conceptual focus around the standard task and hinders employee engagement in broad-scope innovation activities compared to fixed compensation contracts. We contribute to the literature on incentives for innovation by showing that standard task compensation contracts have spillover effects on EII behavior. We also contribute to the nascent literature on EII by showing that innovation types, defined based on their relation with the proponent's standard task, matter. Our results are relevant for practitioners in that managers relying on variable pay contracts to incentivize standard task performance should expect lower employee engagement in broad-scope EII.     

Individual Investors' Attention to Accounting Information: Evidence from Online Financial Communities*

Online financial communities provide a unique opportunity to directly examine individual investors' attention to accounting information on a large scale and in great detail. I analyze accounting-related content in large samples of Yahoo! message board posts and StockTwits and find investors pay attention to a range of accounting information, fixating particularly on earnings, cash, and revenues. Consistent with the expectation that investors react to relevant information events, I find accounting-related discussion elevated around the filings of earnings releases and 8-K reports, but the reaction to periodic reports is confined to small firms. I also find investors expand their acquisition of accounting information and processing efforts in poor information environments. Greater attention to accounting information at earnings releases does not appear to be meaningfully associated with better information processing.     

Targets' Accounting Conservatism and the Gains from Acquisition*

We present evidence on the effects of target firms' accounting conservatism in a merger and acquisition transaction. Conservatism is distinct from other accounting or accrual quality constructs examined in prior work. Its unique features can lead to potential benefits for both the targets and the acquirers. The use of conservatism by targets reduces acquirers' risks of acquiring underperforming assets or overpaying for well-performing assets. In addition, targets' conservatism results in greater production of verifiable information that can help the acquirers better estimate and realize synergies of the combined firm. Consistent with these arguments, we find that firms with greater accounting conservatism are more likely to receive a bid. We also find that targets' conservatism increases the deal premium and the announcement returns of both the targets and the acquirers, respectively. Overall, these results indicate that conservatism provides benefits to both sellers and buyers of equity in an acquisition transaction.     

Private Information Production,Public Disclosure,and the Cost of Capital: Theory and Implications*

Both private information production by market traders and public disclosure by firms contribute to dissemination of financial information in the capital market. However, the motives and economic consequences of the two are quite different. In general, private information production is intended by investors to increase their trading profit, which has the effect of widening the information gap between informed and uninformed investors and increasing the firm's cost of capital. On the other hand, public disclosure can be used to narrow this information gap and to lower the cost of capital. This paper provides a theoretical model to examine the economic incentives behind these two forms of information dissemination and their consequences on the cost of capital. By simultaneously considering the firm's and the information traders' decisions, the paper derives an equilibrium in which the amount of private information production, the level of public disclosure, and the cost of capital are all linked to specific characteristics of the firm, of information traders, and of the market. In contrast to conventional beliefs, the paper predicts that, across firms, the cost of capital can be either positively or negatively related to the firm's disclosure level, depending on the specific factors that cause the variation within a particular sample. Similarly, the extent to which investors follow a firm and the firm's disclosure level can be either positively or negatively related to each other. Implications for empirical research are discussed.     

International Financial Cooperation and the Number of Adherents: The Basel Committee and Capital Regulation

Theoretical analyses of international cooperation point to cooperation being optimized with a small number of participants. History is consistent with this view. However an anomaly is the international capital standards created by the Basel Committee on Banking Supervision (BCBS). Basel I has over 100 adherents, and approximately that number of countries have been identified in a survey as candidates for Basel II. The author demonstrates that this is not an anomaly. First, Basel I was a product of a duopoly and then an oligopoly prior to approval by the BCBS. Secondly, self-interest and other factors explain why more than 100 countries have agreed to accept these standards. JEL Classification Numbers: E58, F33, G15, G28

The Commitment to Income-Decreasing Accounting Choices as a Credible Signal to Reducing Information Asymmetry: The Case of Asset Revaluations*

Bagnoli and Watts (2005) proposed that a manager could reduce information asymmetry by choosing an income-decreasing accounting choice that signals the firm's relatively good future prospects. A limitation in testing this theory is that most income-decreasing accounting choices over time reverse such that aggregated earnings would be the same, regardless of the choice. One income-decreasing accounting choice that never reverses is the choice of upward asset revaluation, where the resulting gains are recognized through other comprehensive income and reduce future earnings by increasing future depreciation expense. In the United Kingdom, prior to FRS15, firms had the option to upwardly revalue on a one-time basis. FRS15, and subsequently International Financial Reporting Standards, however, require those firms that upwardly revalue precommit to revalue on a consistent basis. This precommitment sacrifices future reporting discretion, which, according to the aforementioned study, serves as a costly signal of a firm's relatively good future prospects that reduces information asymmetry. The choice not to upwardly revalue, therefore, serves as a signal of a firm's relatively poor future prospects and also reduces information asymmetry, but this choice does not require precommitment such that the reduction in information asymmetry would be less than the choice to precommit to upward revaluations. Using a propensity-score matched-pair design on a sample of United Kingdom firms to test our predictions during the period requiring precommitment, we find lower forecast dispersion, lower return volatility, and a lower cost of capital for firms that precommit to upward asset revaluations, relative to those firms that choose not to upwardly revalue their operating assets.
