What idiosyncratic consumption risks can countries trade away on international asset markets? This paper develops an empirical methodology for answering the question. The tests are based on the proposition that in an integrated world asset market with representative national agents, the ex post...

This paper is a highly selective review of our knowledge about the scope for sterilized intervention in foreign exchange markets under alternative exchange-rate regimes. Section I demonstrates the potential importance of simultaneous-equations bias in single-equation econometric studies of the...

This paper examines the short-run relation between anticipated inflation and the real rate of interest in a model where agents with perfect foresight maximize utility over infinite lifetimes. In addition to deriving behavioral functions from explicit intertemporal optimization, the approach...

Prevalent thinking about liquidity traps suggests that the perfect substitutability of money and bonds at a zero short-term nominal interest rate renders open-market operations ineffective for achieving macroeconomic stabilization goals. In an earlier paper, we showed that this reasoning does...

This paper presents a long-run model of the open economy in a world of fixed exchange rates and imperfect substitutability between bonds denominated in different currencies. The model explicitly accounts for the wealth flow accompanying current-account imbalance and for the flow of interest...
