Abstract The article is a comment on the article "An Empirical Analysis of the Quality of Corporate Financial Disclosure," by researchers, Surendra S. Singhvi and Harsha B. Desai, published in the January 1971 issue of the journal "The Accounting Review." Singhvi and Desai report on a research project in which they attempted, to identify some of the characteristics of corporations in the United States which are associated with, and the possible implications of, the quality of corporate disclosure. To accomplish their purpose, an index of disclosure was constructed. According to the author, Singhvi and Desai have little to say about how they applied the index. Presumably, they constructed a list of criteria to be met by each item if it were to receive the requisite number of points. However, no mention is made of such a procedure in the article. The lack of specific criteria would tend to give greater play to the variability of human judgment in applying the index. The test, as described by Singhvi and Desai is somewhat misleading.

Abstract This article presents information on the validity of the 1966 tax model and its effectiveness as a research tool. The Internal Revenue Service expects that the 1966 Model will aid researchers in measuring the impact of proposed changes code. The description manual accompanying the model states that, the Individual Tax Model is primarily a research tool that will accurately test hypotheses regarding income, deductions, tax base, tax rates, or any combination of these factors. This paper reports on a validity check on the data underlying the tax model. Specifically, they were concerned with concurrent validity, that is, investigation of the relationship of one set of data to an alternate accepted contemporary measure of the same underlying phenomenon. Tax researchers often desire data on the average dollar amount of an informational item categorized by Adjusted Gross In come (AGI) class. For example, researchers may be interested in the average amount of salaries and wages, dividends, property taxes and so forth, for categories of taxpayers broken down by AgI classes.
