This thesis is an analysis of the Jordanian economic developmental process which demonstrates that it expanded rapidly between 1948 and 1970. During the period under study, Jordan had to face two wars, in 1948 and 1967, which had inverse effects on the economy. After each war, the economy experienced a period of recovery due primarily to government efforts to promote investment; the existence of a more educated people represented by the refugees; and the role of foreign aid. Chapter I is a brief introduction to the Jordanian economy. Chapter II is a discussion of some theories of economic development. Chapters III and IV provide us with a more detailed description of the economic situation before and after the 1967 war. However, the purpose of Chapter V is to incorporate the theory that appears to handle the processes discussed in both Chapters III and IV.
