This paper analyzes weekly scanner data collected for 108 groups at the county level between 2006 and 2014. The data display multi-dimensional weekly seasonal effects that are not exactly periodic but are cross-sectionally dependent. Existing univariate procedures are imperfect and yield...

We provide causal evidence of an ex ante moral hazard effect of Unemployment Insurance (UI) by matching plausibly exogenous changes in UI benefit duration across state-weeks during the Great Recession to high-frequency productivity measures from individual supermarket cashiers. Estimating models...

We show that sticky prices exacerbate household hoarding of storable goods. When stores are slow to adjust prices following a cost shock, households have an incentive to stockpile just as in a typical retail sale. This incentive is present even in the absence of traditional panic or...

Differences between chain and base methods (or strategies) are analyzed. This is a preliminary paper that concentrates on numerical results and new ideas. Omitted proofs will appear in later papers. As in title, we use the term circular or chain error. We do not use milder terms as drift or...

Hoarding of staples has long worried policymakers due to concerns about shortages. We quantify how sticky store prices---delayed price adjustment to shocks by reputable retailers---exacerbate hoarding. When prices are sticky, households hoard not only for precautionary motives but also...

We construct panel price indexes using retail scanner data that allow comparisons of consumption cost across space and time. Two types of panel indexes are examined: the rolling‐window panel extensions of the multilateral Cave‐Christensen‐Diewert index with the Törnqvist index as its...

The use of multilateral indexes is increasingly an accepted approach for incorporating scanner data in a Consumer Price Index. The attractiveness stems from the ability to be able to control for chain drift bias. Consensus on two key issues has yet to be achieved: (i) the best multilateral...

We investigate the effects of carbon reduction labels using a detailed scanner data set. Using a difference‐in‐differences estimation strategy, we find that having a carbon label has no impact on detergent prices or demand. We also investigate possible heterogeneous effects of carbon labels...

In the last 20 years, the expenditure share of prepackaged software in the national output has grown. The large number of characteristics in computer software make hedonic regression techniques impractical for purposes of controlling for quality changes. In this study, matched model price...

This paper considers the potential role of in-home scanners as a method of data collection for national budget surveys such as the Consumer Expenditure Survey. A detailed comparison is made between scanner data and diary-based budget survey data for food at home in the UK. Levels of recorded...

In terms of collecting comprehensive panel expenditure data, there are trade-offs to be made in terms of the demands imposed on respondents and the level of detail and spending coverage collected. Existing comprehensive spending data tends to be cross-sectional whilst panel studies include only...

Microeconomic pricing data display a prevalent pattern: Short term prices vary frequently and in large amounts around repeatedly observed, more stable levels. In response to this observation, authors have proposed various procedures for extracting hypothetical "reference" or "non-sale" price...
