The aggregate collateral constraint is intended to capture an environment in which foreign investors base their lending decisions predominantly upon macro indicators as opposed to individual abilities to pay. Individual agents do not internalize the aggregate borrowing constraint. Instead, in this economy a country interest-rate premium emerges to clear the financial market. The central finding of the paper is that the economy with the aggregate borrowing limit does not generate higher levels of debt than the economy with the individual borrowing limit. That is, there is no overborrowing in equilibrium. ER -
