This Article argues that the norms and legal practices of global finance in the arenas of sovereign debt and private wealth have led to a significant market failure, in particular the over-supply of sovereign borrowing and a related misallocation of global capital away from its most productive...

What are the macroeconomic effects of tax adjustments in response to large public debt shocks in highly integrated economies? The answer from standard closed-economy models is deceptive, because they underestimate the elasticity of capital tax revenues and ignore crosscountry spillovers of tax...

Europe's debt crisis casts doubt on the effectiveness of fiscal austerity in highly-integrated economies. Closed-economy models overestimate its effectiveness, because they underestimate tax-base elasticities and ignore cross-country tax externalities. In contrast, we study tax responses to debt...

What are the macroeconomic effects of tax adjustments in response to large public debt shocks in highly integrated economies? The answer from standard closed-economy models is deceptive, because they underestimate the elasticity of capital tax revenues and ignore cross-country spillovers of tax...

We theoretically illustrate how macroprudential policy spillovers through international capital flows can lead to uncoordinated policy choices that are tighter than would occur with coordination. We consider a symmetric two-country macro model in which countries have limited ability to issue...

This paper considers a two-country macro model where private bond can serve as financial liquidity. With incomplete markets, higher bond liquidity leads to higher growth from more efficient financing of investment opportunities, but also generates higher instability by increasing equilibrium...

Lack of coordination for prudential regulation hurts developing economies but benefits advanced economies. We consider a two-country macro model in which countries have limited ability to issue state-contingent contracts in international markets, and equilibrium is con- strained inefficient....

Ambitious climate policy, coupled with financial frictions, has the potential to create macrofinancial stability risk. Such stability risk may expand beyond the economy implementing climate policy, potentially catching other countries off guard. International spillovers may occur because of...
