ABSTRACT This paper examines the administrative and accounting reforms coordinated by Herman A. Metz around the turn of the 20th century in New York City. Reform efforts were motivated by deficiencies in administering New York City's finances, including a lack of internal control over monetary resources and operational activities, and opaque financial reports. The activities of Comptroller Metz, who collaborated with institutions such as the New York Bureau of Municipal Research, were paramount in initiating and implementing the administrative and accounting reforms in the city, which contributed to reform efforts across the country. Metz promoted the adoption of functional cost classifications for city departments, developed flowcharts for improved transaction processing, strengthened internal controls, and published the 1909 Manual of Accounting and Business Procedure of the City of New York, which laid the groundwork for transparent financial reports capable of providing vital information about the city's activities and subsidiary units.

Initial Decrease

SYNOPSIS We examine whether regulations requiring accelerated filing deadlines and internal control reporting and testing affect financial statement reliability. Unlike prior research, we examine whether these regulatory changes are associated with an increase in the likelihood that misstatements originate in the period following the respective change. If the implementation of these rules causes a misstatement, then the misstatement would most likely occur in the period immediately following the rule change. We provide evidence that accelerated filers (AFs) experience an increase in the likelihood of an originating misstatement following the acceleration of filing deadlines from 90 to 75 days. Large accelerated filers (LAFs), however, do not experience a similar increase following this acceleration or the subsequent acceleration from 75 to 60 days. After the implementation of the SOX Section 404 internal control requirements, we find that the likelihood of an originating misstatement declined for AFs but not for LAFs. Taken together, the findings suggest that, although AFs experienced an initial decrease in financial statement reliability, this decrease was temporary.

SYNOPSIS We investigate the effect of mandatory International Financial Reporting Standards (IFRS) adoption in the European Union on the association between accounting estimates and future cash flows, a key concept of accounting quality within the International Accounting Standard Board conceptual framework. We find that the predictive value of accounting estimates improves after IFRS adoption. This improvement is largely driven by specific types of accounting estimates, such as accounts receivable, depreciation, and amortization expense. We also find that the improvement is concentrated in countries with larger differences between pre-IFRS domestic GAAP and IFRS. Our findings suggest that IFRS allow managers to exercise their judgment to provide information about future cash flows through the more subjective/judgmental portion of accounting accruals.

Accrual Mispricing

SYNOPSIS This study examines the association between mandatory financial reporting frequency and the accrual anomaly. Based on regulatory changes in reporting frequency requirements in Taiwan, we divide our sample period into three reporting regimes: a semiannual reporting regime from 1982 to 1985, a quarterly reporting regime from 1986 to 1987, and a monthly reporting regime (both quarterly financial reports and monthly revenue disclosure) from 1988 to 1993. We find that although both switches (from the semiannual reporting regime to the quarterly reporting regime and from the quarterly reporting regime to the monthly reporting regime) hasten the dissemination of the information contained in annual accruals into stock prices and reduce annual accrual mispricing, the switch to monthly reporting has a lesser effect. Our results are robust to controlling for risk factors, transaction costs, and potential changes in accrual, cash flow persistence, and sample composition over time. These results imply that more frequent reporting is one possible mechanism to reduce accrual mispricing. JEL Classifications: G14; L51; M41; M48.

Client Relationships

SYNOPSIS Upper-division accounting students frequently direct their public accounting careers toward audit or tax “tracks” based on what appears to be limited information. Surprisingly, prior research has not investigated the factors that affect this fundamentally important career decision. We conduct two surveys to investigate the relevant factors of the audit-tax decision from the perspectives of upper-division accounting students and experienced public accounting professionals. Our student survey documents the underlying factors that influence the audit-tax decision. For example, accounting students who plan to pursue careers in audit believe that they will have more client interaction, better future job opportunities (i.e., industry positions), and greater knowledge of business processes if they work in audit (as opposed to tax). In contrast, accounting students who plan to pursue careers in tax perceive that they will have a more stable daily routine, develop more specialized skills, and build more collaborative client relationships if they work in tax (as opposed to audit). While our public accounting respondents agree with many of the students' perceptions, professionals also disagree with several of the students' perceptions, suggesting misimpressions of practice. Our results should be of interest to the accounting professionals, firm recruiters, and accounting professors who advise future accounting professionals.

The Impact

SYNOPSIS Mandatory existence disclosure rules require an organization to disclose a policy's existence, but not its content. We examine policy adoption frequencies in the year immediately after the IRS required mandatory existence disclosure by nonprofits of various governance policies. We also examine adoption frequencies in the year of the subsequent change from mandatory existence disclosure to a disclose-and-explain regime that required supplemental disclosures about the content and implementation of conflict of interest policies. Our results suggest that in areas where there is unclear regulatory authority, mandatory existence disclosure is an effective and low cost regulatory device for encouraging the adoption of policies desired by regulators, provided those policies are cost-effective for regulated firms to implement. In addition, we find that disclose-and-explain regulatory regimes provide stronger incentives for policy adoption than do mandatory existence disclosure regimes and also discourage “check the box” behavior. Future research should examine the impact of mandatory existence disclosure rules in the year that the regulation is implemented.

SYNOPSIS I examine whether firms strategically classify earnings components when reporting bad earnings news. Specifically, I examine whether firms reporting small earnings shortfalls allocate profits across their business segments in a manner that understates the future implications and within-firm drivers of disappointing earnings performance. I find that firms reporting small earnings shortfalls transfer profits toward segments in which profit rates are more informative for firm value and away from segments that operate in industries with higher frequencies of bad earnings news. In addition, I find that shortfall shifting initially tempers negative market responses to shortfall news, but pricing effects reverse in the months following shortfall announcements. My findings suggest that firms strategically classify earnings components when reporting small earnings shortfalls and that strategic classifications temporarily affect the pricing of shortfall news.

ABSTRACT We examine how changing the allocation of hiring decision rights in a multiunit organization affects employee-firm match quality, contingent on a unit's circumstances. Our research site, a U.S. retail chain, switched from a decentralized hiring model (hiring by business unit managers—in our case, store managers) to centralized hiring (in this study, by the head office). While centralized hiring can ensure that enough resources are invested in hiring people aligned with company values, it can also neglect the unit managers' local knowledge. Using difference-in-differences analyses, we find that the switch is associated with relatively higher employee departure rates and, thus, poorer matches if the business unit manager has a local advantage; that is, if the store serves repeat customers, serves a demographically atypical market, or poses higher information-gathering costs for headquarters. In these cases, the unit manager may be more informed than headquarters about which candidates best match local conditions. Data Availability: The analyses presented in this study are based on data shared by a U.S. retail company. The data are confidential, according to a nondisclosure agreement between the company and the authors.
