We investigate biases in expectations across different settings through a large-scale randomized experiment where participants forecast stable stochastic processes. The experiment allows us to control forecasters’ information sets as well as the data generating process, so we can cleanly...

How are a firm’s size and market power related to one another? Combining micro-data about producers and consumers, we document that while firms mainly grow by selling to more customers, their markups are only associated with their average sales per customer. To study the macroeconomic...

We study how biases in expectations vary across different settings, through a large-scale randomized experiment where participants forecast stable random processes. The experiment allows us to control the data generating process and the participants' relevant information sets, so we can cleanly...

We provide closed-form solutions for inflation and GDP dynamics in multi-sector New Keynesian economies with arbitrary input-output linkages. In particular, we show that a sufficient statistic for dynamics of sectoral prices is the principal square root of the Leontief matrix that is...

Can political leaders change constituents’ beliefs? If so, is it rhetoric, identity, or the interaction of the two that matters? We construct a large-scale experiment where participants are exposed to anti-immigrant and pro-immigrant speeches from both Presidents Obama and Trump. We benchmark...

We derive closed-form solutions and sufficient statistics for inflation and GDP dynamics in multi-sector New Keynesian economies with arbitrary input-output linkages. Analytically, we decompose how production linkages (1) amplify the persistence of inflation and GDP responses to monetary and...

This paper explores how different margins of market share are related to markups. Usingmerged microdata on producers and consumers, we document that a firm’s market share ismainly related to its number of customers, while its price-cost markup is associated only withits average sales per...

This paper studies the implications of central bank credibility for long-run inflation and inflation dynamics. We introduce central bank lack of commitment into a standard non-linear New Keynesian economy with sticky-price monopolistically competitive firms. Inflation is driven by the...
