Interest in market power has recently surged among economists in many fields, well beyond its traditional home in industrial organization. This has focused empirical attention on markups, the ratios of price to marginal cost in product markets, and markdowns, the ratios of inputs' marginal...

The substantial fluctuations in oil prices in the wake of the COVID-19 pandemic and the Russian invasion of Ukraine have highlighted the importance of tail events in the global market for crude oil which call for careful risk assessment. In this paper we focus on forecasting tail risks in the...

We must infer what the future situation would be without our interference, and what changes will be wrought by our actions. Fortunately, or unfortunately, none of these processes is infallible, or indeed ever accurate and complete. Knight (1921)

Dealing with endogenous regressors is a central challenge of applied research. The standard solution is to use instrumental variables that are assumed to be uncorrelated with unobservables. We instead assume (i) the correlation between the instrument and the error term has the same sign as the...

We develop a quantitative New Keynesian DSGE model with monopolistic banks to study the macroeconomic effects of introducing a central bank digital currency (CBDC). Households benefit from an expansion of liquidity services and higher deposit rates as bank deposit market power is curtailed,...

We find that an unanticipated tightening of US monetary policy tends to raise US import prices. This empirical "spill-back" pattern differs from the predictions of typical open-economy macro models. We also document a new empirical "spillover" effect: import prices of other countries also rise...

The Federal Reserve's dual mandate, to achieve maximum employment and stable prices, requires monitoring a broad range of indicators and carefully evaluating the trade-offs between these goals. We propose a flow-based framework to evaluate real-time shortfalls from maximum employment, focusing...

We use a novel dataset of production costs, wholesale prices, and retail prices from a large global manufacturer to study markups and pricing behavior along the supply chain. We document several facts about markups covering the period July 2018 through June 2023, and we propose a model of supply...

I describe nine implications of the interconnectedness of fiscal and monetary policy that surface in Heterogeneous Agent New Keynesian (HANK) models. Not all are unique to HANK models. (i) Long run fiscal changes force monetary adjustments. (ii) Sustainable permanent deficits are feasible. (iii)...

Using novel scenario-based survey questions that randomize the expected duration of the Russian invasion of Ukraine and Middle East conflict, we examine the causal impact of geopolitical risk on consumers' beliefs about aggregate economic conditions and their own financial outlook. Expecting a...
