α: calibrated so average coauthorship-adjusted count equals average raw count
The age distribution influences capital flows through aggregate saving and labor supply. To quantify this, I build a dynamic model featuring overlapping generations and international trade among 28 countries since 1970. The equilibrium is replicated by a model with a representative household in each country that experiences an endogenous discount factor, which summarizes the co-evolution of demographics and relevant prices, affording computation of the exact transition. On average, a one-year increase a countrys mean age boosts its current account by 0.4 percent of GDP. Bilateral trade frictions dictate the cross-country response of capital flows to changes in a countrys demographics.
