This paper investigates whether it is possible to entertain simultaneously two attractive views about US GDP. The first is that long term growth in US GDP is attributable to an empirically plausible specification of random technical progress. The second is that deviations of GDP from a fitted...

We compute the forecastable changes in output, consumption, and hours implied by a VAR that includes the growth rate of private value added, the share of output that is consumed, and the detrended level of private hours. We show that the size of the forecastable changes in output greatly exceeds...

We construct a dynamic general equilibrium model in which the typical industry colludes by threatening to punish deviations from an implicitly agreed upon pricing path. We argue that models of this type explain better than do competitive models the way in which the economy responds to aggregate...

This paper develops a welfare-based model of monetary policy in an open economy. We focus on the extent to which monetary policy should be employed in maintaining the exchange rate. The traditional approach maintains that exchange rate flexibility is desirable in the presence of real...

Recent macroeconomic experience has drawn attention to the importance of interdependence among countries through financial markets and institutions, independently of traditional trade linkages. This paper develops a model of the international transmission of shocks due to interdependent...

It is well-known that, in the Mundell-Fleming model, capital mobility creates a channel through which permanent (transitory) shocks to aggregate demand such as fiscal and trade shocks are completely (partially) neutralized by the response of the real exchange rate. An important policy...

The 'International Policy Trilemma' refers to the constraint on independent monetary policy that is forced on a country which remains open to international financial markets and simultaneously pursues an exchange rate target. This paper shows that, in a global economy with open financial...

In the presence of economies of scale in the investment technology, trade openness may have non-conventional effects on the level of investment, its cyclical behavior, and the volatility of the terms of trade. Trade openness may lead to boom-bust cycles of investment supported by self-fulfilling...

In the presence of lumpy investment cost of adjustment, globalization may have non-conventional effects on the level of investment and its cyclical behavior. Trade openness may lead to a discrete 'jump' in the level of investment, as it may trigger a discrete change in the terms of trade. Such a...

Because inputs are scarce, marginal cost should be an increasing function of output. Without changes in this real marginal cost schedule, aggregate output can vary if and only if the markup of price over marginal cost varies. In this review, we discuss the extent to which observed fluctuations...
