SEC product-line reporting and market efficiency

This study tests the efficiency of the securities market with respect to non-public segment earnings data for 1967–1969 which was first made public by many firms in 1970 SEC 10-K reports. Trading rule strategies are proposed in which segment-based earnings forecasts are compared to consolidated-based forecasts to anticipate ‘unexpected’ changes in earnings. Using the ‘market model’ to eliminate market related movements in security prices, average monthly abnormal returns conditional on this segment-based strategy are estimated for 1968, 1969, and 1970 for two groups of firms: (1) ‘Non-disclosure’ firms that did not publicly report either segment revenue or profit data prior to 1970, and (2) ‘partial disclosure’ firms that publicly reported segment revenue information, but no segment profits, prior to 1970.The results suggest that the market was not efficient with respect to the non-public segment revenue and profit data of non-disclosure firms for 1968–1969. However, this finding could not be replicated for 1970. The average monthly abnormal returns conditional on the segment-based trading rule strategy were found to be relatively small for the partial disclosure firms. This suggests that segment revenue data can be used to successfully anticipate changes in total entity earnings which would otherwise be ‘unexpected’ if only consolidated data were available.

Estimating cost of capital in firm valuations with arithmetic or geometric mean – or better use the Cooper estimator?

We test the extent and determinants of bias effects of the arithmetic as well as the geometric mean estimator and the estimator of Cooper [1996. Arithmetic versus geometric mean estimators: Setting discount rates for capital budgeting. European Financial Management 2 (July): 157–67] regarding discount rate estimation for firm valuation by way of a bootstrap approach for 13 different countries. The Cooper estimator is superior to both the geometric and the (conventional) arithmetic mean estimator. However, a ‘truncated’ version of the arithmetic mean estimator leads generally to better estimation outcomes than the Cooper estimator. This means that, in order to reduce problems of upward-biased firm value estimates, expected cash flows beyond a certain time horizon are completely neglected in terminal value estimation. Such an approach seems particularly reasonable for the valuation of young growth companies as well as for companies from quickly developing countries such as Brazil, China, or Thailand, because the bias in terminal value estimation is increasing in the growth rate of future expected cash flows.     

Can intertemporal choice experiments elicit time preferences for consumption?

The paper considers what can be inferred about experimental subjects’ time preferences for consumption from responses to laboratory tasks involving tradeoffs between sums of money at different dates, if subjects can reschedule consumption spending relative to income in external capital markets. It distinguishes three approaches identifiable in the literature: the straightforward view; the separation view; and the censored data view. It shows that none of these is fully satisfactory and discusses the resulting implications for intertemporal decision-making experiments. JEL Classification C90, C91, D90, D91, D11, D12
