 note = {Employing a two-country, one-good, two-period overlapping generations model a la Diamond (1965), this paper considers how a rise in life expectancy in the country with a higher ole-age dependency ratio (the home country) influences the welfare of the country with a lower old-age dependency ratio (the foreign country). In a dynamically efficient steady-state equilibrium, we show that the life expectancy in the home country, when relatively low (high), positively (negatively) affects the welfare of the foreign country. We also show that the reform of unfounded social security in the home country may improve not only domestic welfare but also the welfare of the foreign country.},
