This book provides readers with a comprehensive survey of models of dynamic games in economics, including an extensive coverage of numerous fields of applications. It will also discuss and explain main concepts and techniques used in dynamic games, and inform readers of its major developments while equipping them with tools and ideas that will aid in the formulation of solutions for problems. A Survey of Dynamic Games in Economics will interest those who wish to study more about the conceptions, approaches and models that are applied in the domain of dynamic games.
Optimal control theory is a technique being used increasingly by academic economists to study problems involving optimal decisions in a multi-period framework. This textbook is designed to make the difficult subject of optimal control theory easily accessible to economists while at the same time maintaining rigour. Economic intuitions are emphasized, and examples and problem sets covering a wide range of applications in economics are provided to assist in the learning process. Theorems are clearly stated and their proofs are carefully explained. The development of the text is gradual and fully integrated, beginning with simple formulations and progressing to advanced topics such as control parameters, jumps in state variables, and bounded state space. For greater economy and elegance, optimal control theory is introduced directly, without recourse to the calculus of variations. The connection with the latter and with dynamic programming is explained in a separate chapter. A second purpose of the book is to draw the parallel between optimal control theory and static optimization. Chapter 1 provides an extensive treatment of constrained and unconstrained maximization, with emphasis on economic insight and applications. Starting from basic concepts, it derives and explains important results, including the envelope theorem and the method of comparative statics. This chapter may be used for a course in static optimization. The book is largely self-contained. No previous knowledge of differential equations is required.
During the French colonial period (1900-1945), Vietnamese peasants wrote vigorously about the effects of French policies on their living conditions. The vast majority of their writings were censored or contradicted by the published works of French and Vietnamese officials, and none is currenty in print. Ngo Vinh Long presents a realistic portrait of the Vietnamese determination and resiliency that brought down both the French and the American regimes. He describes the effects of French land policy on the peasants and the resulting problems in tenant farming and sharecropping, as well as peasant reaction to taxes, tax collections, usury, government agarian credit programs, commerce, and industry. He also translates previously unavailable texts that detail the emotions of the Vietnamese people with regard to the French occupation. For the Morningside Edition, Dr. Long has written a new preface in which he describes new scholarship and changes during the last fifteen years.
Productivity dispersion across countries has led to several studies on the determinants of firm level productivity and the role of macroeconomic policies in determining productivity. In this paper, we investigate the effect of fiscal consolidation on firm level productivity in 12 advanced economies by combining an updated dataset of fiscal consolidation measures with firm level productivity. We find that fiscal consolidation (i.e., discretionary tax hikes and spending cuts), is detrimental to firm level productivity in advanced economies. We also find that high levels of fiscal consolidation are particularly harmful to firm level productivity compared to lower levels of fiscal consolidation. Furthermore, we find that tax based fiscal consolidation hinders firm level productivity more compared to spending based fiscal consolidation. This implies that the size and composition of fiscal consolidation matter in understanding the relationship between fiscal consolidation and firm level productivity.
