kiminori matsuyama: engel’s law in the global economy-ag官网

abstract

endogenous demand composition across sectors dueto income elasticity differences, or engel’s law for the brevity, affects i) sectoral compositions in employment and in value-added, ii) variations ininnovation rates and in productivity change across sectors, iii) intersectoral patterns of trade across countries; and iv) product cycles from rich to poorcountries. using a two-country model of directed technical change with acontinuum of sectors under nonhomothetic preferences, which is rich enough to capture all these effects as well as their interactions, this paper offers a unifying perspective on how economic growth and globalization affects the patterns of structural change, innovation and trade across countries and across sectors in the presence of engel’s law. among the main messages is that globalization amplifies, instead of reducing, the power of endogenous domestic demand composition differences as a driver of structural change.
