Noise-independent selection in multidimensional global games

This paper examines many-player many-action global games with multidimensional state parameters. It establishes that the notion of noise-independent selection introduced by Frankel, Morris and Pauzner [D. Frankel, S. Morris, A. Pauzner, Equilibrium selection in global games with strategic complementarities, J. Econ. Theory 108 (2003) 1–44] for one-dimensional global games is robust when the setting is extended to the one proposed by Carlsson and Van Damme [H. Carlsson, E. Van Damme, Global games and Equilibrium selection, Econometrica 61 (1993) 989–1018]. More precisely, our main result states that if an action profile of some complete information game is noise-independently selected in one-dimensional global games, then it is also noise-independently selected in all multidimensional global games.     

Migrants' Home Town Associations and Local Development in Mali

We explore the impact of migrants' Home Town Associations (HTAs) on the provision of public goods in Mali. We combine an original dataset on all the HTAs created by Malian migrants in France from 1981 with census data on public goods in all Malian villages since 1976, and we run double‐difference estimations to compare villages with and without an HTA, before and after the creation of the HTAs. We find robust evidence that the provision of schools, health centers, and, to a lesser extent, water amenities has increased significantly faster in villages targeted by an HTA between 1987 and 2009 than in control villages.     

Environment,public debt,and epidemics

We study whether fiscal policies, especially public debt, can help to curb the macroeconomic and health consequences of epidemics. Our approach is based on three main features: we introduce the dynamics of epidemics in an overlapping generations model to take into account that old people are more vulnerable; people are more easily infected when pollution is high; public spending in health care and public debt can be used to tackle the effects of epidemics. We show that fiscal policies can promote convergence to a stable disease-free steady state. When public policies are not able to permanently eradicate the epidemic, public debt, and income transfers could reduce the number of infected people and increase capital and GDP per capita. As a prerequisite, pollution intensity should not be too high. Finally, we define a household subsidy policy that eliminates income and welfare inequalities between healthy and infected individuals.     

The Value of Crowdsourcing: Can Users Really Compete with Professionals in Generating New Product Ideas?

Generating ideas for new products used to be the exclusive domain of marketers, engineers, and/or designers. Users have only recently been recognized as an alternative source of new product ideas. Whereas some have attributed great potential to outsourcing idea generation to the “crowd” of users (“crowdsourcing”), others have clearly been more skeptical. The authors join this debate by presenting a real‐world comparison of ideas actually generated by a firm's professionals with those generated by users in the course of an idea generation contest. Both professionals and users provided ideas to solve an effective and relevant problem in the consumer goods market for baby products. Executives from the underlying company evaluated all ideas (blind to their source) in terms of key quality dimensions including novelty, customer benefit, and feasibility. The study reveals that the crowdsourcing process generated user ideas that score significantly higher in terms of novelty and customer benefit, and somewhat lower in terms of feasibility. However, the average values for feasibility—in sharp contrast to novelty and customer benefit—tended to be relatively high overall, meaning that feasibility did not constitute a narrow bottleneck in this study. Even more interestingly, it is found that user ideas are placed more frequently than expected among the very best in terms of novelty and customer benefit. These findings, which are quite counterintuitive from the perspective of classic new product development (NPD) literature, suggest that, at least under certain conditions, crowdsourcing might constitute a promising method to gather user ideas that can complement those of a firm's professionals at the idea generation stage in NPD.     

Dynamic talent management capabilities and organizational agility—A qualitative exploration

Today's business environment is becoming increasingly dynamic, and the concept of agility is gaining attention in the corporate world and in academia. The objective of our research is to explain how talent management (TM) can shape talents as key human resources, according to company-specific agility needs, and thus contribute to gaining competitive advantage in dynamic firm environments. We approach this task by viewing it from the perspective of dynamic capabilities. A total of 24 semistructured interviews were conducted with senior TM professionals working in German companies differing in terms of size, age, structure, industry, and ownership. As a result, we identified three different types of dynamic TM capabilities promoting organizational agility to various extents. By rooting our qualitative study in the research fields of TM and agility in the under-researched theoretical realm of dynamic capabilities, we contribute to the theoretical as well as the empirical discussion by addressing the specific challenges of an increasingly dynamic environment. As a result, we provide a contextualized viewpoint from which to explain the process inherent in dynamic TM capabilities that continuously shape talent and organizational agility.
