简述需求收入弹性的类型。
答案
(1)EM>1。这表明需求量的变动率快于收入的变动率,即需求量对收入变化作出的反应程度较大。收入需求曲线斜率为正,其值小于1。称为收入富有弹性。 (2)EM=1。表明需求量的变动率和收入的变动率相等,即需求和收入以相同幅度变动,收入需求曲线斜率为正,其值为1。称为收入单一弹性。 (3)EM<1。表明需求量的变动率慢于收入的变动率,即需求量对收入变化作出的反应程度较小。收入需求曲线的斜率为正,其值大于1,称为收入缺乏弹性。 (4)EM=0。表明需求量为常量,不随收入的变化而变化,收入需求曲线平行于纵轴,其斜率为无限大。 (5)EM<0。表明需求量变动和收入变动成反方向变化,即需求量随收入增加而减少。

Three Effective Management Styles
Being an effective manager means knowing when to use the right management style. Some styles, for instance, are more people-oriented, while others tend to focus on a project or product. The management style you select will depend on your people skills and knowledge, available resources (like time and money), desired results, and, of course, the task before you. The common management styles can be summarized into three categories.
The participatory style is the first of its kind. Here, it is critical to give each employee an entire task to complete. If that’s not possible, make sure the individual knows and understands his or her part as it relates to the project or task. When people in your team know where they fit in the big picture, they’re more likely to be motivated to complete the task.
Following that, we have the directing style. Sometimes a situation will call for a direct style of management. Perhaps a tight deadline looms, or the project involves numerous employees and requires a top-down management approach. Here, a manager answers five questions for the employees: What? Where? How? Why? and When? Let employees know what they need to do, how they’re going to do it, and when the questions must be finished.
The last one is the teamwork style. If you want to speed up a project and choose the best process for completing that project, managing by teamwork is the way to go. When you motivate people to pool their knowledge, the results may exceed your expectations. Often, teams can tackle problems more quickly than what you can accomplish on your own. The give-and-take can create a process that you can repeat in other projects.
