The Optimal Price Index (OPI) stabilization policy traditionally assigns greater importance to stabilize prices in sectors with stickier prices based on multi-sector models with full information or exogenous information frictions. The current paper challenges this prevailing policy prescription...

The introduction of digital price tags and online shopping may facilitate price adjustments and reduce the degree of nominal rigidity in the economy. Is this welfare-improving? We address this question in a multi-sector New Keynesian model with information frictions and dispersed beliefs....

Monetary policy shocks affect interest rates at long horizons (10 years or more). Furthermore, the private sector's real GDP forecasts are revised upward in response to a monetary tightening. These facts challenge the prevailing theories in academic and policy circles. In this paper, I propose a...

Firms’ market power, measured by markups, has risen substantially and unequally across sectors. To evaluate the implications of these trends for monetary non-neutrality, we develop a quantitative menu cost model that covers multiple sectors with heterogeneous degrees of market competition. Two...

What drives macroeconomic tail risk? To answer this question, we borrow a definition of macroeconomic risk from Adrian et al. (2019) by studying (left-tail) percentiles of the forecast distribution of GDP growth. We use local projections (Jordà , 2005) to assess how this measure of risk moves...

Excess sensitivity—the significant effects of monetary policy on long-term interest rates—is a well-known puzzle. This paper documents excess sensitivity as being more pronounced in response to monetary policy easing than monetary tightening—the asymmetric excess-sensitivity puzzle. A...
