Abstract. This research re-examines whether there are differences in the forecast accuracy of financial analysts through a comparison of their annual earnings per share forecasts. The comparison of analyst forecast accuracy is made on both an ex post (within sample) and an ex ante (out of sample) basis. Early examinations of this issue by Richards (1976), Brown and Rozeff (1980), O'Brien (1987), Coggin and Hunter (1989), O'Brien (1990), and Butler and Lang (1991) were ex post and suggest the absence of analysts who can provide relatively more accurate forecasts over multiple years. Contrary to the results of prior research and consistent with the belief in the popular press, we document that differences do exist in financial analysts' ex post forecast accuracy. We show that the previous studies failed to find differences in forecast accuracy due to inadequate (or no) control for differences in the recency of forecasts issued by the analysts. It has been well documented in the literature that forecast recency is positively related to forecast accuracy (Crichfield, Dyckman, and Lakonishok 1978; O'Brien 1988; Brown 1991). Thus, failure to control for forecast recency may reduce the power of tests, making it difficult to reject the null hypothesis of no differences in forecast accuracy even if they do exist. In our analysis, we control for the differences in recency of analysts' forecasts using two different approaches. First, we use an estimated generalized least squares estimation procedure that captures the recency-induced effects in the residuals of the model. Second, we use a matched-pair design whereby we measure the relative forecast accuracy of an analyst by comparing his/her forecast error to the forecast error of another randomly selected analyst making forecasts for the same firm in the same year on or around the same date. Using both approaches, we find that differential forecast accuracy does exist amongst analysts, especially in samples with minimum forecast horizons of five and 60 trading days. We show that these differences are not attributable to differences in the forecast issuance frequency of the financial analysts. In sum, after controlling for firm, year, forecast recency, and forecast issuance frequency of individual analysts, the analyst effect persists. To validate our findings, we examine whether the differences in the forecast accuracy of financial analysts persist in holdout periods. Analysts were assigned a “superior” (“inferior”) status for a firm-year in the estimation sample using percentile rankings on the distribution of absolute forecast errors for that firm-year. We use estimation samples of one- to four-year duration, and consider two different definitions of analyst forecast superiority. Analysts were classified as firm-specific “superior” if they maintained a “superior” status in every year of the estimation sample. Furthermore, they were classified as industry-specific “superior” if they were deemed firm-specific “superior” with respect to at least two firms and firm-specific “inferior” with respect to no firm in that industry. Using either definition, we find that analysts classified as “superior” in estimation samples generally remain superior in holdout periods. In contrast, we find that analysts identified as “inferior” in estimation samples do not remain inferior in holdout periods. Our results suggest that some analysts' earnings forecasts should be weighted higher than others when formulating composite earnings expectations. This suggestion is predicated on the assumption that capital markets distinguish between analysts who are ex ante superior, and that they utilize this information when formulating stock prices. Our study provides an ex ante framework for identifying those analysts who appear to be superior. When constructing weighted forecasts, a one-year estimation period should be used because we obtain the strongest results of persistence in this case. 相似文献

We develop a model in which the mode of acquisition conveys information concerning the value of the bidder. The model incorporates the possibility that offers containing both cash and stock can be made in a setting consistent with the U.S. tax code. We demonstrate that bidders with unfavorable private information about their equity value choose offers containing some stock to avoid the capital gains tax consequences of cash offers. The model yields a number of unique predictions about the construction of acquisition offers. We present evidence consistent with the model. 相似文献

Modeling the incidence of self‐employment has traditionally proved problematic. Although the supply‐side characteristics of the self‐employed are well documented, we argue that the literature has neglected demand‐side aspects. We explore the determinants of self‐employment using the U.S. Survey of Consumer Finances. We present results from an econometric framework that allows us to model, separately and simultaneously, the influences of individual heterogeneity (i.e., supply‐side factors) and employment type heterogeneity (i.e., demand‐side factors) on the probability of self‐employment. Our findings suggest that while individual characteristics are important determinants of self‐employment, there are factors specific to the type of employment that influence self‐employment.

The effects of consumer education and information treatments on choice of alternative products are described. Knowledge of upholstery serviceability and flammability before and after these treatments is measured as well as simulated purchase behavior of 448 Canadian consumers. Subjects show an increase in knowledge between pre- and posttests. The choice of fire resistant upholstery differs among consumer information treatments but not among education treatments. The policy implications of these findings are discussed. 相似文献

This study examines the differences between solar adopters and the general public in their perceptions of solar technologies. Factor analysis confirmed the existence of the theorized dimensions of innovation perception. Discriminant analyses and post hoc comparisons were used to assess differences between adopters, nonadopters, and procrastinators. Models including these facets resulted in significant improvements over a model containing only demographic variables. Results are used to make suggestions for increasing the pace of solar adoption. 相似文献

Liquidity constraints have been proposed as an important explanation for deviations from the rational expectations/permanent income hypothesis. This paper introduces to the liquidity constraint literature the ratio of a household's debt payments to its disposable personal income, the debt service ratio (DSR). We find that a household with a high DSR is significantly more likely to be turned down for credit than other households. Also, the consumption growth of likely constrained households, identified using the DSR along with the liquid‐asset‐to‐income ratio, is significantly more sensitive to past income than that of other households, confirming the DSR's value in identifying constrained households. 相似文献

Recreation researchers have considered coping behaviors one possible explanation for wilderness recreationists' high overall satisfaction levels despite reports of visitor over-crowding and other social conditions exceeding acceptable levels. Studies of recreationists' use of behavioral coping and cognitive coping mechanisms have had mixed results. This study used field-based interviews and surveys to identify coping behavior by hikers in the wilderness areas of New York's Adirondack Park. Findings indicate that wilderness hikers develop complex and variable strategies of coping behavior to maintain multiple satisfactions. 相似文献
