This note again refutes Kuska's proposition that equality between the demand for and supply of money ("money market equilibrium") implies equilibriumin the balance of payments.Indeed, under a regime of fixed exchange rates it is precisely the balance of payments deficit or surplus that...

This paper revisits and proposes a resolution to an empirical and theoretical controversy between Keynes and the "classics" (or monetarists). The controversy dates to Keynes's General Theory (1936)--most famously formalized in Hicks's (1937) classic Econometrica article, in which the IS-LM model...

Gourinchas and Rey (2007) have shown that international financial adjustment (IFA) in the path of expected future returns on a country's international investment portfolio can complement or even substitute for the traditional adjustment channel via a narrowing of country's current account...

Many monetary and fiscal policy decision makers and economists hold the view that exchange rates are volatile even though nominal exchange rates vary less than many other financial market prices and yields. This paper seeks an explanation for this puzzle by contrasting exchange rate dynamics in...

To update a famous old statistic: a political leader in a developing country is almost twice as likely to lose office in the 6 months following a currency crash as otherwise. This difference, which is highly significant statistically, holds regardless whether the devaluation takes place in the...

Emerging markets (sometimes endowed with fertile pampas) have limited access to world capital markets and suffer from original sin: they cannot borrow in their own currency. Does this mean that monetary and exchange rate policy has non-standard effects in such countries? We develop a simple...

We study the relation among exchange rates, balance sheets, and macroeconomic outcomes in a small open economy. Because liabilities are dollarized,' a real devaluation has detrimental effects on entreprenurial net worth, which in turn constrains investment due to financial frictions. But there...

We demonstrate the importance of intertemporal marginal propensities to consume (iMPCs) in disciplining general equilibrium models with heterogeneous agents and nominal rigidities. In a benchmark case, the dynamic response of output to a change in the path of government spending or taxes is...

Modern monetary business-cycle models rely heavily on price and wage rigidity. While there is substantial evidence that prices do not adjust frequently, there is much less evidence on whether wage rigidity is an important feature of real world labor markets. While real average hourly earnings...

We investigate the role of macroprudential policies in mitigating liquidity traps driven by deleveraging, using a simple Keynesian model. When constrained agents engage in deleveraging, the interest rate needs to fall to induce unconstrained agents to pick up the decline in aggregate demand....
