We show that there exists the threshold level of income elasticity of demand for the elder care service, above which population aging spurs economic growth. In a closed economy, the threshold level is unity, whereas it exceeds unity in a small open economy.}, pages = {527--530}, title = {Population aging and sectoral employment shares}, volume = {115}, year = {2012} }
