<p>"This book by Ping Chen and Sardar M. N. Islam discusses the issue of the determination of optimal capital structure for corporations and the economy. They have developed an optimal control model for optimal financing involving a dynamic system with switching times. A new computational method and a new computer program named CSTVA are developed and optimal financing implications of the model results are analysed in this book. This book makes a significant contribution to the literature and will surely prove to be a boon to students, academics, and practitioners in finance, optimal control, and computer programming.” —Professor David W.
