In terms of economics, the twenty-first century promises to be one of experiments and mixed economies that display features of both a private enterprise market and an intrusive government sector. To fully understand this coming trend, William Hixson presents this study of the U.S. economy since World War I and its experiments with mixed economics. Hixson describes how the largely laissez-faire economy prior to 1929 was so structured to make a crisis of illiquidity and overindebtedness inevitable, and how the mixed economy that has prevailed since World War II is structured to result in a similar crisis. His work challenges the generally accepted views of both U.S. and Marxist economists. Following a brief introduction that outlines Hixson's approach and theoretical framework, the book begins with a seven-chapter study of the basic operating principles and procedures of a laissez faire economy. The next three chapters examine the Great Crash of 1929 and how it was a predictable outcome of the U.S. economy's operation in a laissez-faire mode. A set of four chapters then analyze the emergence of the government sector as an increasingly significant factor, and the evolution and institutionalization of mixed economy. The last set of chapters considers the past four decades of a mixed economy and why it lacks long-term viability, while the concluding two chapters suggest changes in operating principles and financial practices to make the mixed economy a viable one. This work will be a valuable resource for professionals involved in all types of financial and investing fields, as well as for students and scholars of economics and national economies.
