Some well-known two-sector models of industrial countries exhibit acrowding out effect or relationship between the main sectors of theeconomy. This is true of the Small Open Economy, traded-non-tradedgood model without nominal wage rigidity, and for the model of the DutchDisease. In contrast, important models of semi-industrialized countries, oreven emerging markets, such as the Bose Model, portray a complimentaryrelation between the various sectors. This paper discusses a possiblesynthesis between these differing model specifications, and tests theapplicability of these models for a large sample of industrial countries,emerging markets and developing economies by analyzing the interlinkagesin their sector growth patterns.
