After reviewing the state of digitalization---the use of digital information technology (IT) throughout the economy---we consider the slippery concept of a distinct digital economy and efforts to record it in national accounts. We then anchor the digital economy in a growth accounting framework,...

We study the implications for optimal monetary policy of introducing habit formation in consumption into a general equilibrium model with sticky prices. Habit formation affects the model's endogenous dynamics through its effects on both aggregate demand and households' supply of output. We show...

We present a new way of empirically evaluating various sticky price models used to assess the degree of monetary non-neutrality. While menu cost models uniformly predict that price change skewness and dispersion fall with inflation, in the Calvo model both rise. However, CPI price data from the...

Starting from the assumption that firms are more likely to adjust their prices when doing so is more valuable, this paper analyzes monetary policy shocks in a DSGE model with firm-level heterogeneity. The model is calibrated to retail price microdata, and inflation responses are decomposed into...

This paper reexamines wage and price dynamics in response to permanent shocks to productivity. We estimate a micro-founded dynamic general equilibrium (DGE) model of the U.S. economy with sticky wages and sticky prices using impulse responses to technology and monetary policy shocks. We utilize...

We examine the role of U.S. monetary policy in global financial stability by using a cross-country database spanning the period from 1870-2010 across 69 countries. U.S. monetary policy tightening increases the probability of banking crises for those countries with direct linkages to the U.S.,...

We study the composition of bank loan portfolios during the transition of the real sector to a knowledge economy where firms increasingly use intangible capital. Exploiting heterogeneity in bank exposure to the compositional shift from tangible to intangible capital, we show that exposed banks...

This paper analyzes the sources of U.S. productivity growth in recent years using both aggregate and industry-level data. We confirm the central role for information technology (IT) in the productivity revival during 1995-2000 and show that IT played a significant, though smaller, role after...

This paper estimates the long run elasticity of the demand for fixed nonresidential capital (both equipment and structures) to changes in its user cost using a quarterly panel of two-digit manufacturing data from South Africa from 1970 to 2001. Using a difference specification that does not rely...

This paper studies optimal debt maturity in an economy with repayment enforcement frictions and investors disagree about repayment probabilities. The optimal debt maturity choice is a mix of long- and short-term debt securities. Spreading risky debt claims on cash flows over time allows debt to...
