Internet odysseys: linking web roles to career and community investments

This paper examines a new kind of career odyssey, namely that into the relatively uncharted territory of the world wide web. It extends recent ideas about personal and communal career investments by exploring people's web-enabled career behaviour, based on Tapscott et al.'s (2000) typology of web roles. MBA students completed a preliminary career exploration instrument and then met in different focus groups according to the web role with which each student most identified. The reported career investments varied depending on the web role involved. An attempt was made to corroborate these findings through practitioner interviews, but there were problems in reconciling the two kinds of data. The implications of these findings are discussed, and a series of observations is offered concerning the further study of the increasingly virtual journeys anticipated for careers of the future.     

The development of political skill and political capital by global leaders through global assignments

The purpose of this paper is to explain how developing global leaders through global assignments (i.e. in the form of expatriation and inpatriation) may lead to their acquisition of valuable political skill and political capital. First, using the theoretical frame of political influence theory, the benefit of political skill is explained relative to the development and augmentation of global leaders' capital portfolio during global assignments. Second, a distinction between social capital and political capital, as the integral components of global leader's capital portfolio, is made. In conclusion, the value of acquiring political skill and building human, cultural, social and political capital by global leaders is discussed separately for expatriate and inpatriate assignments.     

Core equivalence and welfare properties without divisible goods

We study an economy where all goods entering preferences or production processes are indivisible. Fiat money not entering consumers’ preferences is an additional perfectly divisible parameter. We establish a First and Second Welfare Theorem and a core equivalence result for the rationing equilibrium concept introduced in Florig and Rivera (2005a). The rationing equilibrium can be considered as a natural extension of the Walrasian notion when all goods are indivisible at the individual level but perfectly divisible at the level of the entire economy.     

Quasi-structural estimation of a model of childcare choices and child cognitive ability production

This article evaluates the effects of maternal vs. alternative care providers’ time inputs on children’s cognitive development using the sample of single mothers in the National Longitudinal Survey of Youth. To deal with the selection problem created by unobserved heterogeneity of mothers and children, we develop a model of mother’s employment and childcare decisions. We then obtain approximate decision rules for employment and childcare use, and estimate these jointly with the child’s cognitive ability production function. To help identify our selection model, we take advantage of the plausibly exogenous variation in employment and childcare choices of single mothers generated by the variation in welfare rules across states and over time created by the 1996 welfare reform legislation and earlier State waivers.     

Publish or peer-rich? The role of skills and networks in hiring economics professors

This paper analyzes the determinants of success at the concours d'agrégation en sciences économiques. This is a centralized hiring procedure through which professors of economics are selected in France. Using detailed data from all concours held between 1984 and 2003, we focus on the role of the candidates' publication records (number and quality of articles) and networks (defined as professional links between candidates and the jury members who take the recruitment decisions). Both sets of variables have statistically significant effects on the likelihood of getting hired. The effect of network connections is important in the sense that a substantial improvement of the publication record is needed to compensate for not being linked to the jury.     

Combining Matching and Nonparametric Instrumental Variable Estimation: Theory and An Application to the Evaluation of Active Labour Market Policies

We show how instrumental variable and matching estimators can be combined in order to identify a broader array of treatment effects. Instrumental variable (IV) estimators are known to estimate effects only for the compliers, representing a subset of the entire population. By combining IV with matching, we can estimate the treatment effects for the always‐ and never‐takers as well. Since in many cases these groups are the (endogenous) outcome of some assignment process, such estimates also help in judging the implications of such a selection process. In our application to the effects of participation in active labour market programmes in Switzerland, we find large and lasting positive employment effects for the compliers, whereas the effects for the always‐ and never‐participants are small. In addition, the compliers have worse employment outcomes without treatment than those who participate in the programme with or without the intervention under investigation. This suggests that the earlier assignment policy of the caseworkers was inefficient in that the always‐participants were neither those unemployed who would experience the highest expected treatment effects nor those unemployed who had the largest need for assistance.

Anchor stores

Planned shopping malls usually have one or more department (anchor) stores and multiple specialized retailers selling substitutable commodities in each commodity category. If consumers know their taste for the anchor's commodity and its price, but learn about a retailer's commodity only by costly search, collocation may benefit both store types. Intra-mall competition reduces markups, but anchors guarantee a minimum surplus from search. A mall with many retailers makes finding a suitable specialized commodity highly probable. For some parameters, additional consumer search dominates the loss in retail markups, so a profit-maximizing land developer would rent mall space to both store types.     

Relative importance of scheduled macroeconomic news for stock market investors

This paper investigates the relative importance of scheduled U.S. macroeconomic news releases for stock valuation. The study focuses on 11 macroeconomic announcements selected on the basis of the previous literature and the Bureau of Labor Statistics classifications of major economic indicators. The paper shows that five out of the 11 announcements have significant influence on stock valuation. These are the Employment Report, NAPM (manufacturing), Producer Price Index, Import and Export Price Indices, and Employment Cost Index. Of these six announcements, the Employment Report and NAPM (manufacturing) exert the greatest influence. The time of the announcement, measured by days from the beginning of the month to the release day, has a moderating impact on the relationship between macroeconomic announcements and its importance.

The Way to the Top: Career Patterns of Fortune 100 CEOS

How have the CEOs of Fortune 100 companies worked their way to the top position? Are there several paths to the top, or have most present‐day CEOs moved up the ranks in a similar fashion? We examine the employment trajectories of all of the current Fortune 100 CEOs across their entire working careers to answer these questions. The analysis developed in this article is carried out in two steps. We first use sequence analysis to find the patterns that are characteristic of the career paths of these CEOs . We then apply clustering techniques to identify distinct groups of career paths that have led individuals to the uppermost management level. Our results show that the careers of the Fortune 100 CEOs have largely followed traditional career paths that are symbolized by steady progression toward more responsibility, little mobility between firms and industries, and a strong focus on general management functions. © 2015 Wiley Periodicals, Inc.
