Uneven development and the balance of payments constrained model: Terms of trade, economic cycles, and productivity catching-up

This paper addresses (I) the transition dynamics incompatibility between the BPCM and the Prebisch-Singer hypothesis (PSH) (II) the causes of cyclical volatility in developing countries. In order to discuss these issues, we expand the Dutt (2002) model adding: (a) a productivity gap dynamics in which the south has a catching-up element; (b) a labor market dynamics, by including a wage curve in the relationship between employment rate and economic activity; and (c) a labor supply dynamics that considers the labor transfer issue between traditional and modern sectors. The result is a four dimensional dynamic model that represents a lagged developing economy constrained by its balance of payments
