Understanding phenomena such as the recent financial crisis, and possible policy responses, requires the use of a macroeconomic framework in which financial intermediation matters for the allocation of resources. Neither standard macroeconomic models that abstract from financial intermediation...

This paper considers a general class of nonlinear rational-expectations models in which policymakers seek to maximize an objective function that may be household expected utility. We show how to derive a target criterion that is: (i) consistent with the model's structural equations, (ii) strong...

The paper considers optimal monetary stabilization policy in a forward-looking model, when the central bank recognizes that private sector expectations need not be precisely model-consistent, and wishes to choose a policy that will be as good as possible in the case of any beliefs that are close...

U radu se razmatra optimalna politika monetarne stabilizacije unutar dalekovidog modela kada centralna banka uvida da ocekivanja privatnog sektora ne moraju biti nužno konzistentna modelu, i želi da izabere politiku zadovoljavajucu u slucaju bilo kog uverenja dovoljno bliskog konzistentnosti...

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...

This paper reconsiders the Phelps-Lucas hypothesis, according to which temporary real effects of purely nominal disturbances result from imperfect information, but departs from the assumptions of Lucas (1973) in two crucial respects. Due to monopolistically competitive pricing, higher-order...

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 show that modifying the standard neoclassical growth model by assuming that competition is imperfect makes it easier to explain the size of the declines in output and real wages that follow increases in the price of oil. Plausibly parameterized models of this type are able to mimic the...

This paper explains the key factors that determine the output multiplier of government purchases in New Keynesian models, through a series of simple examples that can be solved analytically. Sticky prices or wages allow for larger multipliers than in a neoclassical model, though the size of the...
