This article explores the consequences of extremely low real interest rates in a world with integrated but heterogeneous capital markets, nominal rigidities, and an effective lower bound [a zero lower bound (ZLB) for simplicity]. We establish four main results: (1) At the ZLB, creditor countries export their recession abroad, which we illustrate with a newMetzler diagram in quantities; (2) Beggar-thy-neighbour currency and trade wars provide stimulus to the undertaking country at the expense of other countries; (3) (Safe) public debt issuances and increases in government spendinganywhereare expansionaryeverywhere; and (4) When there is a scarcity of safe assets, net issuers of these assets import the recession from abroad.
