We document a new fact about expectations: in response to the main shocks driving the business cycle, expectations under-react initially but over-shoot later on. We show how previous, seemingly conflicting, evidence can be understood as different facets of this fact. We finally explain what the...

This paper proposes a new equilibrium concept - organizational equilibrium - for models with state variables that have a time-inconsistency problem. The key elements of this equilibrium concept are: (1) agents are allowed to ignore the history and restart the equilibrium; (2) agents can wait for...

This paper develops estimates of TFP growth adjusted for movements in unobserved factor utilization for a panel of 29 countries and up to 37 years. When factor utilization changes are unobserved, the commonly used Solow residual mismeasures actual changes in TFP. We use a general equilibrium...

This paper provides a general and unified framework to study the role of production networks in international GDP comovement. We first derive an additive decomposition of bilateral GDP comovement into components capturing shock transmission and shock correlation. We quantify this decomposition...

We study the role of global supply chains in the impact of the Covid-19 pandemic on GDP growth for 64 countries. We discipline the labor supply shock across sectors and countries using the fraction of work in the sector that can be done from home, interacted with the stringency with which...

We characterize the entire set of linear equilibria of beauty contest games under general information structures. In particular, we focus on equilibria in which sentiments, that is self-fulfilling changes in beliefs that are orthogonal to fundamentals and exogenous noise, can drive aggregate...

We study the roles of globalization and structural change in the evolution of international GDP comovement among industrialized countries over the period 1978-2007. In recent decades, trade integration between advanced economies increased rapidly while average GDP correlations remained stable....

We introduce information frictions into a tractable quantitative multi-country multi-sector model with global value chains. Producers in a sector do not perfectly observe contemporaneous shocks to other countries and sectors, and their output decisions respond to their idiosyncratic beliefs...

We consider a stationary setting featuring forward-looking behavior, higher-order uncertainty, and learning. We obtain an observational equivalence result that recasts the aggregate dynamics of this setting as that of a representative-agent model featuring two distortions: myopia in the sense of...

We study the efficiency of competitive markets when people are rationally inattentive. Appropriate amendments of the Welfare Theorems hold if attention costs satisfy an invariance condition, which amounts to free disposal of decision-irrelevant aspects of the state of nature. This condition is...
