Essay 2
The general density dependence model can be applied to explain the founding of specialist firms (those attempting to serve a narrow target market). According to this model, specialist foundings hinge on the interplay between legitimation and competitive forces, both of which are functions of the density (total number) of firms in a particular specialist population. Legitimation occurs as a new type of firm moves from being viewed as unfamiliar to being viewed as a natural way to organize. At low density levels, each founding increases legitimation, reducing barriers to entry and easing subsequent foundings. Competition occurs because the resources that firms seek--customers, suppliers, and employees--are limited, but as long as density is low relative to plentiful resources, the addition of another firm has a negligible impact on the intensity of competition. At high density levels, however, competitive effects outweigh legitimation effects, discouraging foundings. The more numerous the competitors, the fiercer the competition will be and the smaller will be the incentive for new firms to enter the field.
While several studies have found a significant correspondence between the density dependence model and actual patterns of foundings, other studies have found patterns not consistent with the model. A possible explanation for this inconsistency is that legitimation and competitive forces transcend national boundaries, while studies typically restrict their analysis to the national level. Thus a national-level analysis can understate the true legitimation and competitive forces as well as the number of foundings in an industry that is internationally integrated. Many industries are or are becoming international, and since media and information easily cross national borders, so should legitimation and its effects on overseas foundings. For example, if a type of firm becomes established in the United States, that information transcends borders, reduces uncertainties, and helps foundings of that type of firm in other countries. Even within national contexts, studies have found more support for the density dependence model when they employ broader geographic units of analysis--for example, finding that the model's operation is seen more clearly at the state and national levels than at city levels.
Q7:
The primary purpose of the passage is to B---E
A. question the validity of an economic model
B. point out some inconsistencies within an economic model 细节
C. outline an economic model and suggest revisions to it 无
D. describe an economic model and provide specific examples to illustrate its use 无
E. explain why an economic model remains valid despite inconsistent research results
我是这么想这题,是掐时间做的,所以没有特别多的时间考虑,现在再看的时候觉得B明显错了.
但是A E 我还是不能够很好的判断,我想问CDers的是：（１）怎么判别A和 E,文章中有明显的提示词吗?还是从文章总体套路把握?
我再研究的时候觉得整个P2都在讨论inconsistence,那又怎么决定文章到底是支持Ｐ１还是 支持Ｐ２，我觉得他好象是说两种情况，并且还是
equally expression
(2)在考试当期，时间很紧张没多余的时间思考，这题应当是找提示词吗？
看大家没人讨论，想必在时间限定下都做对了吧，怎么我一下就做错了？复习这篇ｅｓｓａｙ的时候还搞不清楚．．．．
谢谢，帮我解答下吧，， |
