This lecture presents a broad overview of postwar analytical thinking on international macroeconomics, culminating in a more detailed discussion of very recent progress. Along the way, it reviews important empirical evidence that has inspired alternative modeling approaches, as well as...

We explore the consequences of safe asset scarcity on aggregate demand in a stylized IS-LM/Mundell Fleming environment. Acute safe asset scarcity forces the economy into a "safety trap" recession. In the open economy, safe asset scarcity spreads from one country to the other via capital flows,...

I show that the indivisible labor' models of Diamond and Mirrlees (1978, 1986), Hansen (1985), Rogerson (1988), Christiano and Eichenbaum (1992), and many others are, when aggregated across persons with the same marginal utility of income, equivalent to the divisible labor model of Lucas and...

Both the literature and new empirical evidence show that exchange rate regimes differ primarily by the noisiness of the exchange rate, not be measurable macroeconomic fundamentals. This motivates a theoretical analysis of exchange rate regimes with noise traders. The presence of noise traders...

This paper examines what industrial organization economists know and don't know about how markets clear. It reviews the empirical evidence which shows that, at least for some industries, price behavior is peculiar with prices failing to adjust over long periods of time. The paper discusses...

This paper explains prices, output and employment adjustment In an open economy characterized by a monopolistic competitive market structure where goods prices are flexible while wages are determined by contracts that pre-set the wage path for several periods. The paper solves the rational...

Supply shocks played an important role in macroeconomic fluctuations during the 1970's. Supply shocks are also increasingly important in Keynesian and neo-classical models of the business cycle. This paper is a short survey of these theoretical models. It also discusses the history of supply...

This paper makes use of the simulation results of 12 leading large international econometric models, as to the effects of commonly specified changes in monetary and fiscal policy, conducted under the Brookings exercise "Empirical Macroeconomics for Interdependent Economies." The first half of...

In 1944 Franco Modigliani published a famous article summarizing the Keynesian model; in 1963 he extended the 1944 framework. This paper,written for a conference in honor of Modigliani, asks how the earlier papers would be modified in the light of recent developments in macroeconomics. The...
