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...

The Covid pandemic disrupted supply chains and labor markets, with heterogeneous effects on demand and supply across industries. Meanwhile governments responded with unprecedented stimulus packages, and inflation increased to its highest values in 40 years. In this paper I investigate the...

The high social costs of financial crises imply that economists, policymakers, businesses, and households have a tremendous incentive to understand, and try to prevent them. And yet, so far we have failed to learn how to avoid them. In this article, we take a novel approach to studying financial...

Using a new dataset on sectoral credit exposures covering financial and non-financial sectors in 115 economies over the period 1940-2014, we document the following evidence that corporate debt plays a key role in explaining boom-bust cycles, financial crises, and slow macroeconomic recoveries:...

We develop a simple menu-cost model with non-constant elasticity of demand that features idiosyncratic productivity and demand shocks. The model is calibrated to match firm-level productivity and demand processes estimated from U.S. data. Despite its simplicity, the calibrated model delivers...

In a collaborative project with ten central banks, we have investigated the causes of the post-pandemic global inflation, building on our earlier work for the United States. Globally, as in the United States, pandemic-era inflation was due primarily to supply disruptions and sharp increases in...

Most macroeconomic models view economic outcomes as being generated by a combination of endogenous and exogenous dynamic forces. In particular, the exogenous forces are generally modelled as a set of independent dynamics processes. In this paper we begin by showing that this dual dynamic...

We study how within-store price variation changes with inflation, and whether households exploit it to attenuate the inflation burden. We use micro price data for food products sold by 91 large multi-channel retailers in ten countries between 2018 and 2024. Measuring unit prices within narrowly...

To understand a price boom, it is helpful to take account of: (1) observable indicators of changes in ex ante risk tolerance, (2) what information exists and when, and (3) the incentives lenders face. This paper takes such an approach to the Florida land boom of the mid-1920s, the U.S.' first...

We study the joint evolution of prices and rents of residential property. After constructing rent and price indices for renter- and owner-occupied properties, we decompose the change in the price of occupant-owned property into (1) changes in rent, (2) changes in the relative prices of investor-...
