Charting the difficulties to the top: A study of executive mobility patterns

It is odd with all the emphasis today on developing managerial personnel that little effort is given to discovering who is progressing and regressing and at what rates.     

The LeChatelier principle: the long and the short of it

Summary. Using ordinary calculus techniques, we investigate the conditions under which LeChatelier effects are signable for finite changes in parameter values. We show, for example, that the short run demand for a factor is always less responsive to price changes than the long run demand, provided that the factor of production and the fixed factor do not switch from being substitutes to being complements (or vice versa) over the relevant range of the price change. The absence of a sign change in the complementarity/substitutability relation holds under conditions that are considerably more general than supermodularity of the production function.     

LGB+ identification and donations to Hurricane Irma victims: The role of empathy

Extant literature finds that discrimination promotes empathy towards other people in similar predicaments. We propose that discrimination increases empathy more generally—namely, LGB+ individuals, because of their experience with discrimination in society, which promotes empathy, are more charitable than heterosexual individuals. We recruited 5,131 American respondents of whom 378 identified as LGB+. LGB+ -identifying respondents scored higher on empathy, increasing their monetary donations to victims of Hurricane Irma, relative to heterosexual respondents. Importantly, greater experience with discrimination enhanced LGB+ respondents' empathy and charity. We situate our results within literature that has studied the charitable behaviors of LGB+ individuals. We acknowledge limitations to our study and suggest ideas for further research.     

Visual Attention and Attribute Attendance in Multi‐Attribute Choice Experiments

Decision strategies in multi‐attribute choice experiments are investigated using eye‐tracking. The visual attention towards, and attendance of, attributes is examined. Stated attendance is found to diverge substantively from visual attendance of attributes. However, stated and visual attendance are shown to be informative, non‐overlapping sources of information about respondent utility functions when incorporated into model estimation. Eye‐tracking also reveals systematic nonattendance of attributes only by a minority of respondents. Most respondents visually attend most attributes most of the time. We find no compelling evidence that the level of attention is related to respondent certainty, or that higher or lower value attributes receive more or less attention.

Mutual fund performance evaluation with active peer benchmarks

We propose a simple approach to account for commonalities in mutual fund strategies that relies solely on information on fund returns and investment objectives. Our approach augments commonly used factor models with an additional benchmark that represents an equal investment in all same-category funds, which we call an active peer benchmark (APB). We find that APBs substantially reduce the average time series correlation of residuals between individual funds within a group when added to a four-factor equity model (or to a seven-factor fixed-income model). Importantly, adding this APB significantly improves the selection of funds with future outperformance.     

SPATIAL PRICE EQUILIBRIUM AND PRICE VARIABILITY: AN APPLICATION TO THE FALL POTATO INDUSTRY*

The purpose of this paper is to show that spatial price equilibrium models with stochastic supply functions can be solved and that such solutions contain some interesting information. The solution procedure suggested is relatively uncomplicated, requiring only quadratic programming routines available to most researchers. Estimates of price distributions which result from this approach can be quite useful for price forecasting and for decision making at firm and industry levels. The importance of the additional information obtained by solving these models stochastically is discussed in connection with a amplified model of the United States fall potato industry. Results of the application reveal that changing production patterns have given rise to substantive shifts in annual prices distributions in important consumption areas. EQUILIBRE ET VARIATIONS DANS LES PRIX DE PRODUCTION DES POMMESDE TERRE D'AUTOMNE - Cette communication a pour objet de démontrer qu'il y a moyen d'établir un équilibre des prix en function des approvisionnements de denrées et que les solutions possibles contiennent plusieurs éléments intéressants. La solution proposée est relativement simple et s'obtient par la methode de programmation quadratique qu'utilisent constamment la plupart des chercheurs. Les données auxquelles on arrive à l'aide de cette méthode permettent d'établir des projections de prix qui ont lew utilité tant au niveau des entreprises qu'à celui de l'ensemble de ce secteur de l'économie. Pour bien faire comprendre la valeur des renseignements additionnels obtenus par cette méthode, qui est basée sur les prix et les approvisionnements, on recourt, à titre d'exemple, à une analyse simplifiée de la situation telle qu'elle existe dans le secteur de la production des pommes de terre d'automne, aux Etat-Unis. Il s'avère, en somme, que les transformations qui se produisent au niveau de la production influent de façon radicale sur les prix qui sont obtenus chaque année dans les grands centres de consummation.
