The advent of a pandemic is an exogenous shock, but the dynamics of contagion are very much endogenous --and depend on choices that individuals make in response to incentives. In such an episode, economic policy can make a difference not just by alleviating economic losses but also via...

We study the effects of monetary and fiscal policies when both money and government bonds provide liquidity services. Because money is the unit of account, the price of money is the inverse of the price level. If prices are sticky, so is the price of money in terms of goods, and this is one...

This paper develops a political-economic model of fiscal policy one in which" government resources are a common property' out of which interest groups can finance" expenditures on their preferred items. This setup has striking macroeconomic implications. " First, fiscal deficits and debt...

This paper develops a political-economic model of fiscal policy - one in which government resources are a common property' out of which interest groups can finance expenditures on their preferred items. This setup has striking macroeconomic implications. Transfers are higher than a benevolent...

This paper analyzes the sustainability of fixed exchange rates by extending the Barro-Gordon framework to a fully dynamic context in which the level of a state variable (in this case debt) determines the payoffs available to the government at each point in time. The model yields the following...

We provide a conceptual and empirical framework for evaluating the effects of short-term capital flows. A simple model of the joint determination of the maturity and cost of external borrowing highlights the role played by self-fulfilling crises. The model also specifies the circumstances under...

We build a model of financial sector illiquidity in an open economy. Illiquidity defined as a situation in which a country's consolidated financial system has potential short-term obligations in foreign currency that exceed the amount of foreign currency it can have access to on short notice can...

In a standard two-sector neoclassical model with distortions, capital mobility can render the steady state indeterminate, in the sense that there exist infinitely many convergent paths. In the closed economy with no international capital mobility, the utility function must be linear or close to...

Exchange rate policies depend on portfolio choices, and portfolio choices depend on anticipated exchange rate policies. This opens the door to multiple equilibria in policy regimes. We construct a model in which agents optimally choose to denominate their assets and liabilities either in...

We revisit the question of what determines the credibility of macroeconomic policies here, of promises to repay public debt. Almost all thinking on the issue has focused on governments' strategic decision to default (or erode the value of outstanding debt via inflation/devaluation). But...
