Do sophisticated international financial markets obviate the need for an active union-wide authority to orchestrate fiscal transfers between countries to provide adequate insurance against country-specific economic fluctuations? We argue that they do. Specifically, we show that in a benchmark...

The massive expansion of central-bank balance sheets in response to recent crises raises important questions about the effects of such "quantitative easing" policies, both their effects on financial conditions and on aggregate demand (the intended effects of the policies), and their possible...

"Leaning against the wind" (LAW), that is, tighter monetary policy for financial-stability purposes, has costs in terms of a weaker economy with higher unemployment and lower inflation and possible benefits from a lower probability or magnitude of a (financial) crisis. A first obvious cost is a...

"Liability dollarization,'' namely intermediation of capital inflows in units of tradables into domestic loans in units of aggregate consumption, adds three important effects driven by real-exchange-rate fluctuations that alter standard models of Sudden Stops significantly: Changes on the debt...

We develop a quantitative equilibrium model of financial crises to assess the interaction between ex-post interventions in credit markets and the buildup of risk ex ante. During a systemic crisis, bailouts relax balance sheet constraints and mitigate the severity of the recession. Ex ante, the...

We use a simple model of a closed economy to study the recommendations of monetary policy-makers, attempting to respond optimally to an asset-price bubble whose stochastic properties they understand. We focus on the impact which the zero lower bound (ZLB) on nominal interest rates has on the...

We analyze conventional and unconventional monetary policies in a dynamic small open-economy model with financial frictions. In the model, financial intermediaries or banks borrow from the world market and lend to domestic households. Banks can borrow abroad up to a multiple of their equity; in...

We develop a two-sector, heterogeneous-agent model with incomplete financial markets to study the distributional effects and aggregate welfare implications of alternative monetary policy rules in emerging market economies. Relative to inflation targeting, exchange rate management benefits...

Identification problems arise naturally in forward-looking models when agents observe more than economists. We illustrate the problem in several New Keynesian and macro-finance models in which the Taylor rule includes a shock unseen by economists. We show that identification of the rule's...

The paper presents a model of a monetary economy where there are differences in liquidity across assets. Money circulates because it is more liquid than other assets, not because it has any special function. There is a spectrum of returns on assets, reflecting their differences in liquidity. The...
