Rough Set Theory is a powerful mathematical tool to handle vagueness and uncertainty of dynamic evaluation. By the application of Rough Set Theory, this paper computes the significance and weights of each evaluation criterion and helps to lay evaluation emphasis on the main and effective criteria. From the reduced decision table,evaluators can get decision rules Which direct them to give judgment or suggestion of strategy. The whole evaluation process is decided by data, so the results are certain and reasonable.展开更多

On the basis that we compare the degree of IPO underpricing in different underwriters and the underpricing condition between prestigious and non-prestigious underwriters, we go further to make regression analysis of the underwriter prestige and IPO underpricing which they underwrite. Finally we conclude that the offering price marketalization is still very low and the underwriter prestige does system is put into effect. not significantly impact on IPO underpricing after approval展开更多
