This thesis first outlines the main theoretical approaches to the consumption function, such as the Absolute Income Hypothesis, the Relative Income Hypothesis, the Life-Cycle Hypothesis and the Permanent Income Hypothesis. Furthermore, it highlights the importance of expectations for consumption behavior and presents an econometric specification of the consumption function, utilizing the adaptive and rational expectations formation mechanisms. Important empirical issues regarding the inclusion of other determinants of consumption are also discussed. Finally, an econometric analysis of consumption for Greece, Germany, France, Italy and the United Kingdom is presented.

This study examines the significance and implications of Dividend Reinvestment Plans (DRPs) for the sponsoring company and for the shareholders' wealth from a theoretical and an empirical point of view. It develops a DRP theory, as an extension of dividend and capital structure theories. Furthermore, the study tests empirically several hypotheses related to the market reaction at the announcement of a DRP adoption, to the market reaction at the announcement of a DRP discontinuance and to the performance of the company sponsoring a DRP. The results indicated that the market reaction to the announcement of a DRP establishment is favorable on days 1 and 2, significant only for the latter. In the long-run, DRPs create value for the sponsoring firm and its shareholders (as measured by Tobin's Q). The announcement of a DRP termination is followed by a negative market reaction, consistent with the thesis of this study. Finally, several factors such as the DRP type (Type I and Type II plans), the industry of the sponsoring company (utilities and non-utilities), tax legislation, the discount feature and the dividend payout ratio are examined in relation to the market reaction at the announcement of a DRP adoption. The Type II DRPs create more favorable reaction to Type I plans at the announcement of their introduction. There are significant differences between the market reaction at the DRP introduction of utilities and non-utilities. The tax legislation affects corporate dividend policy and DRPs. Finally, the discount feature is not regarded favorably by investors as it was hypothesized, which explains its elimination from many DRPs in the recent years.
