مدل رشد چند بخشی تراز پرداخت محدود با ناهمگونی بخشی

This study builds a multi-sectoral balance-of-payments-constrained growth model that incorporates structural heterogeneity between sectors and countries, such as differences in labor productivity, price competition, shares of exports and imports, and the quality of commodities. The model in the current paper generates more comprehensive results than those presented by Thirlwall (1979), Blecker (1998), and Araujo and Lima (2007), even though it contains their properties and reproduces their implications. Furthermore, compared with these existing works, the current model sheds more light on the relationship between the trade structure, international competition, productivity dynamics, and economic growth. It also shows the differences between industrial and macroeconomic phenomena, by presenting an example that illustrates how changes in nominal wages, the Kaldor–Verdoorn effect, and the degree of market competition in both countries affect economic growth in the home country.
