The adoption of the incentive-signalling framework gives a reasonably good explanation of the corporate dividend decision. The equilibrium optimal dividend decision under such a framework is presented and analyzed, assuming a reward-penalty managerial incentive scheme is used. It is shown that the size of the declared dividend is an increasing function of expected cash flow. However, there exists a trend that points out that the higher the level of expected cash flow, the lower the marginal effects of cash flow on dividends. A similar relationship is observed with respect to changes in expected cash flows. These conclusions are in harmony with “real world” behavior as reported by several empirical studies. The effects of uncertainty and interest rates on dividends are also analyzed. It is shown, in agreement with observed phenomena, that the higher the uncertainty, the lower the dividend/payout ratio.

ABSTRACT Investments in default‐free bonds can be insulated from financial loss due to interest rate changes (via additive shock) by a process known as immunization. The literature on this process ignores taxes. This manuscript focuses on three issues. The first is the development of the tax‐adjusted immunization process with a comparison to the existing literature. The second issue is the microeconomic effect of a shift in only the individual's tax rates on immunization and investment behavior. The third issue is the macroeconomic effect of an across‐the‐board shift in tax rates on immunization and investment behavior.
