This paper provides the comprehensive survey on the effect of economic growth on the Harris-Todaro economy with a few new findings. Through the specific-factor model and general-factor model, it is examined how each growth factor, which consists of factor accumulation and technological progress, affects the urban unemployment rate, its amount and the social welfare in the short run and the long run. We reconfirm the effects of factor accumulation which are discussed in the previous works: in the short run, while labor growth increases urban unemployment, capital accumulation contributes to decreasing it. In the long run, however, the effects opposite to the ones established in the short run are obtained, which is often said to be “paradoxical”. We also reveal that this “paradoxical” effect in the long run strongly relies on the assumption of constant returns to scale in the production technologies. Once its assumption relaxed, the model could show the more plausible effects of factor accumulations: while capital accumulation decreases the urban unemployment, the labor growth increases it. In addition, we apply the general form of technological progress to the model and rigidly re-examine how the economy is affected by the various type of technological progress including non-neutral type of one. We show that in the short run, both the technological progress in agricultural sector and that in manufacturing sector decrease the urban unemployment rate. In the long run, while the technological progress in agricultural sector decreases the urban unemployment, that in manufacturing increases it. As for the change of social welfare, it is shown that each growth factor always improves the social welfare and that immiserizing growth never occurs in the Harris-Todaro economy.
