Some believe that the market is sufficiently efficient to be explained by the hypotheses. Others believe that investor behavior and preferences will influence the price drop on the ex-dividend date.his paper analyzes the effects of the introduction of the imputation tax system on the behavior of dividend price drops in Taiwan from 1995 to 2001. We found that there is a shift in trend for more companies to distribute cash dividends, and that the ex-dividend price drop ratio increased which suggests that shareholders increased their value of dividends relative to capital gains.Table of Contentshapter 1 Introduction 1.1 Purpose and Motivation 1.2 Thesis Structure 3hapter 2 Tax Systems 5.1 Tax Systems: Overview 5.2 Imputation in Taiwan - A Detailed Description 7hapter 3 Literature Review 12.1 Classical Tax Literature 12.2 Imputation Tax System Literature 15hapter 4 Data and Methodology 17.1 Data Sources 17.2 Methodology 19hapter 5 Empirical Results 24.1 Results Analysis 24hapter 6 Conclusion and Comments 32.1 Conclusions 32.2 Comments 34.3 Future Research 35eferences 36application/pdf839752 bytesapplication/pdfen-US除權除息兩稅合一Ex-DividendIntegrated TaxImputation TaxImputation CreditPrice Drop Ratiothesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/182530/1/ntu-96-R94723073-1.pdf
