This paper attempts to measure the rate of change in the size distribution of wages over time in a rigorous, analytic way, and to relate that change to the business cycle. The basic problem for which this paper provides a solution is to relate changes in a size distribution to levels of and changes in single-dimensioned variables (unemployment, Gross National Product, and the consumers price index). Let F stand for the cumulative relative size distribution of wages, a function of wages. F takes on values zero through one. Let be a given value of F , e.g., = 0.25. The proposed solution to the basic problem is to measure the rate of change in consecutive F 's at . The composite of such measurements at over time forms a vector, the length of which depends upon the number of time periods observed. The number of vectors thus derived depends upon the number of values of selected. The various vectors are then related to the general economic conditions and the respective values of . The general economic conditions have a differential effect on the various vectors; e.g., those wage earners with relatively low wages are affected differently by a given turn of the business cycle than are those with high wages.
The paper includes several supplementary investigations: (a) estimating each of the annual cumulative relative size distributions of wages for a specific analytic function, (b) relating analytically the size distribution construct to the Lorenz curve concept and the Gini coefficient, (c) predicting and simulating size distributions for various economic conditions, (d) formulating tax trade-offs, and (e) suggesting further uses and extensions.  相似文献

Crowdsourcing presents new opportunities to generate social innovation. However, many crowdsourcing social innovation initiatives struggle with turning their promising projects into sustaining platforms. We studied how to design crowdsourcing platforms for social innovation by building and examining a platform called travel2change. We illustrate a framework of crowdsourcing platform building blocks based on the evolution of our case study from a collaborative community to a competitive market. Thriving platforms have a clear purpose, they facilitate value‐creating interactions for well‐understood actors and build a valid business model. The insights reveal design principles to guide organizations that seek to leverage crowdsourcing for social impact.  相似文献

Even in today’s turbulent business environment, there are companies in many industries that have enjoyed decades of relatively undisturbed success. However, eventually, after such prolonged periods of calm, existing market positions are challenged. We describe such companies as ‘Sleeping Beauties’ and discuss how they can reinvent themselves through opening up of their boundaries and moving from compartmentalized exploitation and exploration efforts to a more dynamic ambidexterity model. We analyse Swarovski’s open innovation journey in this regard, instigated as a response to recent changes in its business environment. Our analysis of this process offers useful insights for companies struggling with similar problems.  相似文献

This article investigates techniques for the assessment of model error in the context of insurance risk analysis. The methodology is based on finding robust estimates for actuarial quantities of interest, which are obtained by solving optimization problems over the unknown probabilistic models, with constraints capturing potential nonparametric misspecification of the true model. We demonstrate the solution techniques and the interpretations of these optimization problems, and illustrate several examples, including calculating loss probabilities and conditional value-at-risk.  相似文献
