The creation of jobs is critical in Third World countries where growing populations face unemployment or inadequate employment. Many have put forth theories and suggestions that address this problem, but there has been insufficient empirical analysis of the effects of specific policies on employment growth. The author examines macroeconomic theories of labour market behavior and labour force definitions and concepts, assessing how productive they are in formulating employment strategies for Colombia. The implications of a range of alternative policies for generating jobs, their effectiveness in reducing unemployment, and possible programs for the future are analyzed.
