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.     

Tests for model specification in the presence of alternative hypotheses: Some further results

In Davidson and MacKinnon (1981), two of the present authors proposed a novel and very simple procedure for testing the specification of a nonlinear regression model against the evidence provided by a non-nested alternative. In this paper we extend their results in several directions. First, we relax a number of the assumptions of the previous paper; we admit the possibility that the nonlinear regression functions may depend on lagged dependent variables, and we do not require that the error terms be normally distributed. Second, we show how the earlier procedure may straightforwardly be generalized to the case where the two non-nested models involve different transformations of the dependent variable. Finally, we propose a simple procedure for testing non-nested linear regression models which have endogenous variables on the right-hand side, and have therefore been estimated by two-stage least squares.     

Codetermination and technological change in the German automobile industry*

This article examines how works councils in the West German automobile industry have influenced management approaches to technological change in three firms. The authors argue that while the post-war industrial relations consensus in Germany can be increasingly questioned, car-makers in the English speaking countries have important lessons to learn from their German counterparts.     

On testing separability restrictions with flexible functional forms

In this paper, we examine the implications of imposing separability on the translog and three other flexible forms. Our results imply that the Berndt-Christensen ‘nonlinear’ test for weak separability tests not only for weak separability, but also imposes a restrictive structure on the macro and micro functions for all currently known ‘flexible’ functional forms. For example, testing for weak separability using the translog as an exact form is in fact equivalent to testing for a hybrid of strong (additive) separability and homothetic weak separability with Cobb-Douglas aggregator functions. Our results show that these ‘flexible’ functional forms are ‘separability-inflexible’. That is, they are not capable of providing a second-order approximation to an arbitrary weakly separable function in any neighbourhood of a given point.     

An investigation of certain interactions between large CPA firms and accounting educators

Some accounting educators have questioned whether selected interactions between the “Big Eight” accounting firms (Firms) and accounting educators might affect the academic freedom and independence of accounting educators. This study compares the current and normative attitudes of accounting professors about certain areas of these interactions and concludes that a significant difference exists between the attitudes of the current and the normative groups. The implications of this finding are discussed.
