In studies concluding that public debt may hamper GDP growth, the debt tipping effects are estimated as if there were a single global currency.

This paper examines the fiscal and monetary policy options available to China as a sovereign currency-issuing nation operating in a dollar standard world. We first summarize a number of issues facing China, including the possibility of slower growth, global imbalances, and a number of domestic...
