Under efficient consumption risk sharing, as assumed in standard international business cycle models, a country’s aggregate consumption rises relative to foreign consumption, when the country’s real exchange rate depreciates. Yet, empirically, relative consumption and the real exchange rate...

This Paper analyses the effects of pegged and floating exchange rates using a two-country dynamic general equilibrium model that is calibrated to the US and a European aggregate. The model assumes shocks to money, productivity and the interest parity condition. It captures the fact that the...

Kocherlakota and Pistaferri (EJ, 2007) [KP] develop a model of a world economy with private-information Pareto optimal (PIPO) risk sharing; in that model, the real exchange rate tracks relative domestic/foreign cross-sectional distributions of consumption. KP claim that the PIPO model fits the...

Recent empirical research documents that an exogenous rise in government purchases in a given country triggers a persistent depreciation of its real exchange rate - which raises an important puzzle, as standard macro models predict an appreciation of the real exchange rate. This paper presents a...

This Paper computes welfare-maximizing monetary and tax policy feedback rules, in a calibrated dynamic general equilibrium model with sticky prices. The government makes exogenous final good purchases, levies a proportional income tax, and issues nominal one-period bonds. A quadratic...

This paper explains three key stylized facts observed in industrialized countries: 1) portfolio holdings are biased towards local equity; 2) international portfolios are long in foreign currency assets and short in domestic currency; 3) the depreciation of a country‘s exchange rate is...

This Paper analyses the welfare effects of monetary policy rules in a quantitative business cycle model of a two-country world. The model features staggered price setting, and shocks to productivity and to the uncovered interest rate parity (UIP) condition. UIP shocks have a sizable negative...

This paper explores the link between the leverage of the US financial sector, of households and of non-financial businesses, and real activity. We document that leverage is negatively correlated with the future growth of real activity, and positively linked to the conditional volatility of...

This paper incorporates a global bank into a two-country business cycle model. The bank collects deposits from households and makes loans to entrepreneurs, in both countries. It has to finance a fraction of loans using equity. We investigate how such a bank capital requirement affects the...

This Paper computes welfare maximizing Taylor-style interest rate rules, in a business cycle model of a small open economy. The model assumes staggered price setting and shocks to domestic productivity, to the world interest rate, to world inflation and to the uncovered interest rate parity...
