Specialization is a powerful source of productivity gains, but how production networks at the industry level are related to aggregate productivity in the data is an open question. We construct a database of input-output tables covering a broad spectrum of countries and times, develop a...

This paper estimates the impact of external demand shocks on real income. Our empirical strategy is based on a first order approximation to a wide class of small open economy models that feature sector-level gravity in trade flows. The framework allows us to measure foreign shocks and...

This paper develops a model where firms make state-dependent decisions on both pricing and acquisition of information. It is shown that when information is not perfect, menu costs combined with the aggregate price level serving as an endogenous public signal generate rigidity in price setting...

At the firm level, revenue and costs are well measured but prices and quantities are not. This paper shows that because of these data limitations estimates of returns to scale at the firm level are for the revenue function, not production function. Given this observation, the paper argues that,...

Using a new survey of firms' inflation expectations in France, we provide novel evidence about the measurement and formation of inflation expectations on the part of firms. First, French firms report inflation expectations with a smaller, but still positive, bias than households and display less...

Using surveys of firms around the world, we review existing evidence on how firms form their macroeconomic expectations. Several facts stand out. First, the mean inflation forecasts of firms often deviate significantly from those of professional forecasters and households. Second, disagreement...

Households' and firms' subjective inflation expectations play a central role in macroeconomic and intertemporal microeconomic models. We discuss how subjective inflation expectations are measured, the patterns they display, their determinants, and how they shape households' and firms' economic...

Using responses obtained through the Nielsen Homescan panel survey, we explore the differences between managers' and non-managers' expectations and perceptions of inflation and unemployment. By and large, managers and non-managers exhibit similar average inflation and unemployment expectations...

We document a new fact: in U.S., European and Japanese surveys, households do not expect deflation, even in environments where persistent deflation is a strong possibility. This fact stands in contrast to the standard macroeconomic models with rational expectations. We extend a New Keynesian...
