How to eliminate the uncovered market: A duopoly model with government intervention

To eliminate poverty, government intervention is critical for addressing uncovered markets. To assess how this can be done effectively, this study constructs a two-firm model with government intervention. The study focuses on the preconditions, methods, and effects of different government intervention strategies. There are three main findings. (1) When consumer income levels fall below a certain threshold, an uncovered market segment is created, and government intervention should be introduced. (2) Government intervention strategies can be divided into subsidy-type, production-type and mixed-type, and each type achieves a different level of consumer surplus. Given a level of consumer surplus, the optimal strategy is affected by production costs. (3) For production-type and mixed-type intervention strategies, when the market is covered, lower intervention costs can achieve higher consumer surplus if government production costs are low. Furthermore, the optimal subsidy-type intervention strategy varies with the changes in product quality if relaxing the precondition of market coverage.     

员工地位竞争动机、知识分享行为与创新绩效——基于嵌入性悖论视角

组织中个体创新常常面临嵌入性悖论。相对于传统地位竞争的反功能视角，人们日益认识到地位竞争尤其是威望型地位竞争，可以为个体提供创新资源和动力。有效化解这一悖论，关键在于明晰何种类型的地位竞争以及何种程度的嵌入性可以促进个体创新。对一家大型多业务单元传媒集团227名员工进行实证调查，分析结果表明：威望型地位竞争可以通过促进个体知识分享行为提升个体创新绩效；非正式地位较低的个体更有可能具有威望型地位竞争动机；正式地位与非正式地位对个体地位竞争动机有交互影响，处于高正式地位的成员如果在非正式网络中处于边缘位置，则更可能在地位竞争中表现出威望型地位竞争动机。
