    Extrapolative Expectations and Capital Flows during Convergence
    (NH Elsevier, 2017-09) ;
    How long shall a country take to learn the world technological frontier? What would happen if that country found the same difficulties in learning the true model of its economy? After all, countries catching up often experience life-changing transformations during the catch-up to a balanced growth path. We show that an open economy, learning rational expectations alongside foreign technology, may be characterized by excessive saving and current account surpluses, as often observed in the data and at odds with the standard open economy theoretical predictions, and not fully explained by standard adaptations such as habit formation. Moreover, such a learning process in a large developing country can upset the savings behavior of a fully rational expectations advanced country. In a US-China calibration, we show that this effect can be so strong as to explain important current account imbalances, the savings glut hypothesis, as well as the distribution of factor income.

    Demography, Capital Flows and International Portfolio Choice over the Life-cycle
    ( 2016) ;
    Mann, Katja
    In an aging world, how does a country's demographic structure impact global trades in safe and risky assets and their respective prices? We answer these questions combining portfolio choice over the life-cycle with a two-region, general equilibrium model. We show that when one region is aging faster than the other, its demand for both safe and risky assets increases, whereas a greater portfolio share is allocated into safe assets. Absent perfectly elastic supply, this results in a change in autarky rates and, in an open economy, in international asset trades. Calibrating the model to the U.S. and Europe, we predict a positive net external equity position and a negative net external debt position for the U.S. The model allows us to quantitatively assess the impact of demographic change on trade in various types of assets, whereas previously, the focus has been on aggregate capital flows. In addition, general equilibrium price effects can explain a significant portion of the valuation effects present in international foreign asset positions.
