We document how supply-chain pressures, household inflation expectations, and firm pricing power interacted to induce the pandemic-era surge in consumer price inflation in the euro area. Initially, supply-chain pressures increased inflation through a cost-push channel and raised inflation...

Empirical evidence has long shown that output varies more in the short-run than do all factor inputs, including employment and hours worked. There is also evidence that all factors, including capital, start adjusting within a few months, suggesting that production models should treat all...

If stock-outs are ignored and if demand shocks are additive, then optimal behavior requires that the marginal cost of production (MC) be equated with the expected marginal revenue of increasing expected sales by one unit (EMR). However,with more general demand shocks (and still ignoring...

This paper provides a statistical test to assess the adequacy of static equilibrium models. The test is based on a restricted cost function framework together with the envelope conditions which characterize static equilibrium for the quasi-fixed factors. We also show how restricted cost function...

The central thesis of this paper is that the management of portfolios incorporating a variety of investment assets does require the use of time and other scarce resources in searching for, collecting, interpreting, and applying relevant information. Accordingly, the returns on these assets would...

Conventional models of production under uncertainty specify that output is produced in fixed proportions across states of nature. I investigate a representation of technology that allows firms to transform output from one state to another. I allow the firm to choose the distribution of its...

Costs of attention, while central to choice behavior, have proven hard to measure. We introduce a simple method of recovering them from choice data. Our recovery method rests on the observation that costs of attention play precisely the same role in consumer choice as do a competitive firm's...
