The purpose of this dissertation is to study the planning and budgeting processes in Jordan to determine whether the findings of Caiden and Wildavsky about those processes in other poor countries generally are applicable to Jordan. An attempt is made to answer the research questions by comparing data from national plans, budgets, and expenditures during a fifteen-year period (1970-1984). In Jordan, as in other developing nations, the role of planning and budgeting is highly significant to the success of the country's hopes for development. This research tries to evaluate the role of planning and budgeting as policy instruments in the process of development in Jordan. The second focus of the dissertation concerns the possibilities and problems of assessing the impact of governmental policies on development. Specifically, an assessment is made to determine the impact of governmental expenditures on development as evidenced in Jordan s gross national product during the last fifteen years. The following questions are addressed in order to examine the impact of government action on economic development. First, what are the impact and significance of government expenditures, as a combined measure, on the gross national product in Jordan? Second, which governmental expenditure areas provide the greatest contribution to an increase in the Jordanian GNP? Data for Jordan are compared with Caiden and Wildavsky's assumptions about planning and budgeting in poor countries, and conclusions are drawn about how planning and budgeting have influenced economic and social development in Jordan.
