The various components of financial structure management are usually discussed in isolation with little concern for the other components. A unified model of financial structure management bridging these components has not yet been developed. This dissertation seeks to establish such an underpinning by combining Miller and Orr's cash management model with contemporary corporate finance theory, and is able to address a wide range of questions while retaining a comprehensible format. I simulate the proposed strategy to show the consequences of implementation, and to provide hypotheses about the behavior of financial variables characterizing the firm as a result of implementing this strategy. / Ph.
