The Relation of Stock Prices to Corporate Earnings Adjusted for Inflation
The effects of inflation adjustments of corporate earnings on market prices were tested by cross section regressions of 485 manufacturing companies for the period 1966-76 and subperiods. The basic data were company reports and stock prices. For the full period, market prices reflected the inventory valuation adjustment and the decline in real value of net financial liabilities fairly completely, but they reflected the adjustment for the understatement of depreciation to only a small extent. The surprisingly low effect of the depreciation adjustment could only be partly attributed to measurement error, but not entirely. The estimated effect of capital gains on stock prices was either in the wrong direction or negligible. The implication of the results is that market investors use a range of adjustments for the effects of inflation which differs from the estimates used in this study, though how and why they differ is not clear. The adjustments were much lower in the later period 1972-76 than in the earlier period 1966-71. This seemed inconsistent with the higher inflation rates in the later period. The explanation for the difference is not clear, but it may reflect the difficulties of judging the size of the adjustments in a period of rapid inflation.
Imported Inflation 1973-74 and the Accommodation Issue
The purpose of the present study is to measure the amount of price increase that the proposals for accommodation required in 1973-74. Presumably such an estimate of the amount could be made in time to act on it. Whether accommodation is a desirable policy is not addressed here. Consistently followed, it would result in a higher long-run rate of inflation, because there are not likely to be nearly enough episodes of deflationary accommodation to offset the inflationary ones. Notwithstanding the appeal in the short run to accept inflationary fait accompli in order to avoid prolonged economic slack, one may have strong reservations about the long-run consequences on expectations of following such a policy.
The development of biological systematics : Antoine-Laurent de Jussieu, nature, and the natural system
A reevaluation of the history of biological systematics that discusses the formative years of the so-called natural system of classification in the eighteenth and nineteenth centuries. Shows how classifications came to be treated as conventions; systematic practice was not linked to clearly articulated theory; there was general confusion over the "shape" of nature; botany, elements of natural history, and systematics were conflated; and systematics took a position near the bottom of the hierarchy of sciences.
