Price selection is a simple, model-free measure of selection in price setting and its contribu- tion to in ation dynamics. It exploits comovement between in ation and the level from which adjusting prices departed. Prices that increase from lower-than-usual levels tend to push in a- tion above...

Rising consumer prices may reflect shifts by consumers to new higher-priced products, mostly for durable and semi-durable goods. I apply Bils' (2009) methodology to newly available Canadian consumer price data for non-shelter goods and services to estimate how price increases can be divided...

We use a detailed micro dataset on product availability to construct a direct high frequency measure of consumer product shortages during the 2020-21 pandemic. We document a widespread multi-fold rise in shortages in nearly all sectors early in the pandemic. Over time, the composition of...

Macroeconomists have traditionally ignored the behavior of temporary price markdowns ("sales") by retailers. Although sales are common in the micro price data, they are assumed to be unrelated to macroeconomic phenomena and generally filtered out. We challenge this view. First, using the 1996 -...

The rise in inflation in 2021-22 sparked a growing literature and debate over the causes of the surge as well as the near- and medium-term path for inflation. This review offers three key messages. First, the exceptional nature of shocks resulting from the COVID-19 pandemic and geopolitical...

For most of 2011-19, inflation in Canada and advanced economies registered below inflation targets. This has spurred a debate on whether "lowflation" is a temporary phenomenon or rather a sign of a fundamental change in inflation behaviour-in Canada and globally. So far, we know little. Global...

Standard theories of price adjustment are based on the problem of a single-product firm, and therefore they may not be well suited to analyze price dynamics in the economy with multiproduct firms. To guide new theory, we study a unique dataset with comprehensive coverage of daily prices in large...

We study a unique dataset with comprehensive coverage of daily prices in large multi-product retailers in Israel. Retail stores synchronize price changes around occasional "peak" days when they reprice around 10% of their products. To assess aggregate implications of partial price...

This paper measures the welfare gains of switching from inflation-targeting to price-level targeting under imperfect credibility. Vestin (2006) shows that when the monetary authority cannot commit to future policy, price-level targeting yields higher welfare than inflation targeting. We revisit...
