We show analytically that in a rational expectations present value model, an asset price manifests near random walk behavior if fundamentals are I(1) and the factor for discounting future fundamentals is near one. We argue that this result helps explain the well known puzzle that fundamental...

Major changes have taken place in the U.S. economy within the past quarter century. Changes with implications that are at least potentially important for the effect of monetary policy on real economic activity include the elimination of Regulation Q interest ceilings and the development of the...

This paper explores the effect of news shocks on the current account and other macroeconomic variables using worldwide giant oil discoveries as a directly observable measure of news shocks about future output–the delay between a discovery and production is on average 4 to 6 years. We first...

We present a model embodying moderate amounts of nominal rigidities which accounts for the observed inertia in inflation and persistence in output. The key features of our model are those that prevent a sharp rise in marginal costs after an expansionary shock to monetary policy. Of these...

We develop a flexible semiparametric time series estimator that is then used to assess the causal effect of monetary policy interventions on macroeconomic aggregates. Our estimator captures the average causal response to discrete policy interventions in a macro-dynamic setting, without the need...

Evaluating inflation-targeting monetary policy is more complicated than checking whether inflation has been on target, because inflation control is imperfect and flexible inflation targeting means that deviations from target may be deliberate in order to stabilize the real economy. A modified...

Using the "trilemma indexes" developed by Aizenman et al. (2008) that measure the extent of achievement in each of the three policy goals in the trilemma--monetary independence, exchange rate stability, and financial openness--we examine how policy configurations affect macroeconomic...

We study the macroeconomic consequences of tariffs. We estimate impulse response functions from local projections using a panel of annual data that spans 151 countries over 1963-2014. We find that tariff increases lead, in the medium term, to economically and statistically significant declines...

We propose and apply a new approach for analyzing the effects of fiscal policy using vector autoregressions. Specifically, we use sign restrictions to identify a government revenue shock as well as a government spending shock, while controlling for a generic business cycle shock and a monetary...
