Author Order and Research Quality

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.     

Reexamining momentum profits: Underreaction or overreaction to firm-specific information?

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.     

Earnings Response Coefficients and Dividend Policy Parameters

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.

Econometric Analysis of the India–Sri Lanka Free Trade Agreement*

This paper investigates whether the India–Sri Lanka Free Trade Agreement (ISLFTA) has had trade creation or trade diversion effects on the rest of the world. Using data on tariffs at the six‐digit level of the Harmonized System classification for the period 1996 to 2006, the methodology of the present paper follows a study on the North American Free Trade Agreement by Romalis (2005 ) We use the commodity and time variation in the tariff preferences allowed under ISLFTA to identify its effect on sourcing of different products from the ‘control country’ to the ISLFTA region. Using a fixed effects model, we find that the ISLFTA has had small trade creation effects in the control countries.     

Evaluating the Adequacy of Parametric Functional Forms in Estimating Monotone and Concave Production Functions

We consider situations where the a priori guidance provided by theoretical considerations indicates only that the function linking the endogenous and exogenous variables is monotone and concave (or convex). We present methods to evaluate the adequacy of a parametric functional form to represent the relationship given the minimal maintained assumption of monotonicity and concavity (or convexity). We evaluate the adequacy of an assumed parametric form by comparing the deviations of the fitted parametric form from the observed data with the corresponding deviations estimated under DEA. We illustrate the application of our proposed methods using data collected from school districts in Texas. Specifically, we examine whether the Cobb–Douglas and translog specifications commonly employed in studies of education production are appropriate characterizations. Our tests reject the hypotheses that either the Cobb–Douglas or the translog specification is an adequate approximation to the general monotone and concave production function for the Texas school districts.     

Additional analyses of recent segment disclosures of Japanese firms

This paper discusses additional issues concerning segment reporting in Japan. Specifically, it discusses what the relevant segment reporting standards are, enforcement issues, the interaction of consolidation standards with segment disclosures, survey biases and response rates and the implications of segment disclosures in Japan for global investors and accounting standard setting bodies.     

The intellectual structure of the strategic management field: an author co-citation analysis

This paper complements a recent study by Ramos-Rodriguez and Ruiz-Navarro (2004) that investigated the intellectual structure of the strategic management field through co-citation analysis. By using authors as the units of analysis and incorporating all the citations that are included in the Science Citation Index and the Social Science Citation Index, we trace the evolution of the intellectual structure of the strategic management field during the period 1980–2000. Using a variety of data analytic techniques such as multidimensional scaling, factor analysis, and Pathfinder analysis, we (1) delineate the subfields that constitute the intellectual structure of strategic management; (2) determine the relationships between the subfields; (3) identify authors who play a pivotal role in bridging two or more conceptual domains of research; and (4) graphically map the intellectual structure in two-dimensional space in order to visualize spatial distances between intellectual themes. The analysis provides insights about the influence of individual authors as well as changes in their influence over time. Copyright © 2007 John Wiley & Sons, Ltd.
