基于传染病模型的口碑传播预测

早在上个世纪五六十年代就有人提出过口碑营销的概念,这是一种以消费者自己为导向自发宣传企业产品的一种效应。多年来,关于如何高效地利用口碑营销价值的问题得到了众多学者的关注,但主要研究内容都侧重于不变数目人群消费圈子的传播效应预测,以及口碑营销的纯理论研究机制,缺乏对动态人数变化的分析。故本文侧重于对消费移出者这样一种动态趋势的口碑营销现象进行研究,采用微分方程模型的方法,对消费者口碑效应做一个简单地预测。本文的研究对实际生活中的营销投入有一定的参考借鉴价值。     

UK Unions,Collective Action and the Cost Disease

This article looks at the financial resources of trade unions in the UK. The core argument is that trade unions are subject to ‘cost disease’ pressures such that costs rise over the long term above the general level of inflation. They have this property because of the difficulty in solving first- and second-order collective action problems. First-order problems refer to the problems of initiating collective action and second-order problems refer to the management of collective action organizations. Both UK aggregate and case-study data — from one of the largest UK unions, Unite — are presented to illustrate the cost disease problem and to suggest options for its management. In conclusion, the wider implications of ‘cost disease’ pressures for unions are assessed.

The United Mine Workers of America dealt with this problem primarily through agitation for legislative reform.
