New product introduction with costly search

In the usual model of product market search, a low search cost can turn out to have detrimental incentives on new product introduction as the low search cost erodes firms’ market power, attenuating the profit from innovation. This paper studies a model of monopolistic competition with costly search, where the point of departure is that of a fixed cost of initiating search. In this environment, a low search cost could turn out to be favorable to innovation. At a low search cost, more consumers may decide to start searching, possibly resulting in higher profits for firms in the larger market, despite the erosion of market power.     

The medical expense deduction and income levels: Progressive or regressive?

The medical expense deduction (MED) allows taxpayers to deduct from taxable income a proportion of their out-of-pocket medical insurance and health care expenses. Because the rate of subsidy is equal to the marginal tax rate previous studies have found MED to be a regressive tax mechanism biased toward benefiting higher-income taxpayers. The authors demonstrate, using GINI coefficients, that MED makes the tax structure more progressive than it would otherwise be and increases equality of after-tax incomes.     

Utilization of SFAS No. 14 disclosures in assessing operating risk

This paper examines the usefulness of segmental disclosures required by SFAS No. 14 in assessing the operating risk of the firm. It is shown that the segmental asset data required by SFAS No. 14 is theoretically linked to an assessment of operating risk. In addition, an empirical investigation is conducted to examine whether this new disclosure was material enough to cause a reassessment by market participants of the operating risk of the affected firms. Segmental disclosure policy implications of the findings of this study are also discussed.

Auditor independence and nonaudit services: Director views and their policy implications

The external auditor's role and relationship with an audit client are not purely matters of private concern between the two parties. The rationale for the external auditor's work—indeed a primary justification for the existence of the public accounting profession—arises from the need for reliable financial information in order for our economy to operate smoothly. Thus the auditor, in certifying financial statements, performs a quasi-public function. The necessary relationship between auditor and client is one of complete independence. In recent years public policymakers including the U.S. Congress have questioned the propriety of auditors' performing nonaudit services for their clients. This paper reports the results of an empirical study of U.S. corporate directors who considered the propriety of allowing a firm's auditors to perform various nonaudit service engagements.The results show, especially in the case of systems design, increasing director concern and a lack of overall consensus as nonaudit services approach 40 percent of the firm's audit fee. Policy implications of the findings are considered.     

The Relation between Aggregate Earnings and Security Returns over Long Intervals*

This paper provides a theoretical explanation and consistent empirical evidence for the increase in the contemporaneous correlation between returns and aggregate earnings as the return interval is lengthened. Consistent with intuition and with Easton, Harris, and Ohlson 1992, the analysis shows that aggregation over time renders the lag in accounting recognition relatively less important and thus improves the returns‐earnings R². Interestingly, the analysis also reveals that aggregating earnings over longer periods increases the positive covariance between aggregate earnings and the accounting lag, which may further increase the R². This positive covariance can lead to an earnings coefficient greater than one over some range of aggregation, which is consistent with the findings of Easton et al. that over the 10‐year interval the returns‐earnings regression slope coefficient is greater than one (1.7). The empirical results highlight the fact that the slope coefficient, which is greater than one and increasing with the interval, accounts for much of the increment to the returns‐earnings R². In fact, constraining the slope coefficient to be one results in an R² of 11 percent for the 10‐year interval, which is considerably lower than the R² of 47 percent when the regression is unconstrained. Hence, the positive covariance between current earnings and the accounting lag, rather than the diminishing effect of the accounting lag, appears to be the dominant explanation for the observed high R² over long intervals.
