There is very little research on the topic of buy-side analyst performance, and that which does exist yields mixed results. We use a large sample from both the buy-side and the sell-side and report several new results. First, while the contemporaneous returns to portfolios based on sell-side recommendations are positive, the returns for buy-side analysts, proxied by changes in institutional holdings, are negative. Second, the buy-side analysts' underperformance is accentuated when they trade against sell-side analysts' recommendations. Third, abnormal returns positively relate to both the portfolio size and the portfolio turnover of buy-side analysts' institutions, suggesting that large institutions employ superior analysts and that superior analysts frequently change their recommendations. Abnormal returns are also positively related to buy-side portfolios with stocks that have higher analyst coverage, greater institutional holding, and lower earnings forecast dispersion. Fourth, there is substantial persistence in buy-side performance, but even the top decile performs poorly. These findings suggest that sell-side analysts still outperform buy-side analysts despite the severe conflicts of interest documented in the literature. 相似文献

This paper considers the generalised second-best analytics of optimal restructuring under a political constraint, building on the modelling approach in Dehejia (1997, CEPR Discussion Paper No. 1552, Centre for Economic Policy Research, London, January 1997). It is shown that the second-best optimum entails administering the terms-of-trade shock fully at the initiation of the reform, just as in shock therapy, but that this must be supplemented with interventions in domestic factor markets. The effects of these interventions are to speed up the exit of the politically affected factor, labour, and to retard the exit of the other factor, capital, both of which serve to prop-up the wages of workers in the declining sector and hence address the political constraint. The results are in the spirit of the neoclassical theory of distortions and welfare: the optimal intervention targets the affected margin directly, in consonance with the ‘targeting’ principle of Bhagwati–Ramaswami–Johnson. 相似文献

This systematic review analyses literature on the work of hybrid value creation, i.e. the process of generating additional value by innovatively combining products (tangible component) and services (intangible component). A state of the art report on hybrid value creation is delivered by first systematically identifying and then analyzing 169 publications focusing on hybrid value creation. The identified publications are clustered into eight categories based on their links and interactions and thus a mapping of this evolving field is suggested. A discussion and reflection of the findings with respect to the pervasiveness of literature and the research methodologies used is provided. The paper concludes by identifying some dominant strategic gaps in the overall research landscape and provides directions for future research. 相似文献

This paper conducts an empirical investigation to assess the impact of price uncertainty on industry output concentration. Results show that greater price uncertainty leads to greater output concentration; the result is robust to controls for technological factors, barriers to entry effects and other industry controls. The empirical results are consistent with theory which shows that depending on firms attitudes towards risk, output concentration is likely to be endogenous to price uncertainty. Our empirical finding suggests that examining the magnitude of uncertainty could be a useful additional criteria in antitrust policymaking. 相似文献

We observe a great deal of heterogeneity in the manner in which author orderings are assigned both across and within academic markets. To better understand this phenomenon, we develop and analyze a stochastic model of author orderings. In our model, authors work equally hard to obtain priority in listings but final contributions are stochastic. Further, research outlets differ in their quality hurdles. In this setting, our simulation results are consistent with two empirical regularities. First, we find that the rate of alphabetization increases with the stringency with which papers are accepted for publication. Second, conditional on clearing the publication hurdle, quality increases with alphabetization. These findings arise because increases in the publication hurdle make it more likely that authors will exceed this threshold only when both contribute a high amount. This, in turn, leads to roughly equal contributions (alphabetization) and also generates a positive correlation between alphabetization and quality. 相似文献

For knowledge‐intensive industries, a need remains to increase clarity on the dynamics through which business model innovation occurs. Progress has been limited owing to complexities in these industries and to the underlying ontology of the business model concept itself. Through a conceptual methodology, our findings expose impediments to current business model theory and propose economic evolutionary theory as a useful alternative lens through which to address these limitations. This research contributes to the literature by broadening the traditional scope of the economic evolutionary view as relevant for business model innovation research and by offering a corresponding framework for future research. 相似文献

We design a new measure and find that the predictability of past returns on future returns increases as stocks respond with delay to firm-specific information. Our results suggest that momentum is caused by both investors’ underreaction and overreaction to information. However, underreaction to information seems to be the primary cause, particularly during the more recent period. Our findings are robust for recent explanations of momentum profits and alternative methods for computing our measure. We also find that stocks respond with delay to firm-specific information, partly due to certain firm characteristics, and partly because they escape investor attention due to their low visibility. Our paper extends and refines Jegadeesh and Titman’s (J Financ 56(2):699–720, 2001) finding that momentum profits are consistent with behavioral models’ predictions regarding investors’ overreaction. 相似文献

In a seminal paper. Ball and Brown (1968) documented a positive statistical association between earnings surprises and stock returns around an earnings announcement. They concluded that accounting earnings conveyed ‘useful’ information to the market. However, the question of how accounting earnings convey useful information is still being understood. Recent work on this topic has found that current accounting earnings aid investors and analysts in predicting future accounting earnings. Few studies, however, have examined the usefulness of current earnings for predicting other value-relevant attributes. A model by Ohlson (1989a) suggests that investors are also interested in the relationship between current earnings and future dividends. Ohlson's model is supported by empirical tests in this paper which show that the relationship between current earnings and future dividends is significant in explaining cross-sectional variation in earnings response coefficients (ERCs). A second result of interest is that information in dividends substitutes for that in accounting earnings. We find that dividend policy parameters reflect information contained in current earnings. These results add new insights on the information revealed through the analysis of ERCs. Consistent with logic presented here, a symmetrically opposite result is found with respect to dividend response coefficients. The informativeness of earnings (dividends) is found to be negatively (positively) related to the information content of dividends. 相似文献
