This paper investigates the use of trimmed means as high-frequency estimators of" inflation. The known characteristics of price change distributions, specifically the observation" that they generally exhibit high levels of kurtosis, imply that simple averages of price data are" unlikely to...

Two strands of the literature suggest that PPI inflation, rather than CPI inflation, should be the targeting variable in a monetary policy rule. The distinction between these two rules would only be important if the two inflation indices do not co-move strongly. The first contribution of this...

We analyze the effects of China's rapid export expansion following WTO entry on U.S. prices, exploiting cross-industry variation in trade liberalization. Lower input tariffs boosted Chinese firms' productivity, lowered costs, and, in conjunction with reduced U.S. tariff uncertainty, expanded...

We examine the price and variety of products at the barcode level in cities within China and the United States. In both countries, there is a greater variety of products in larger cities. But in China, unlike the United States, the prices of products tend to be lower in larger cities. We...

This paper estimates a cost of living index for 39 states of the United States and the District of Columbia, as well as for 70 individual cities and towns, for the year 1890. It gives an overall index in addition to seven commodity subindices (food, clothing, housing, fuel and lighting,...

Variance decompositions of the Mexico-United States real exchange rate are examined using monthly data on consumer prices and the nominal exchange rate for the period January, 1969 to February, 2000. The results show that the robust result found in industrial-country data that most of the...

Inflation equals the product of two terms: an extensive margin (the fraction of items with price changes) and an intensive margin (the average size of those price changes). The variance of inflation over time can be decomposed into contributions from each margin. The extensive margin figures...

This paper shows that the products and prices offered in markets are correlated with local income-specific tastes. To quantify the welfare impact of this variation, I calculate local price indexes micro-founded by a model of non-homothetic demand over thousands of grocery products. These indexes...

The Covid-19 Pandemic has led to changes in consumer expenditure patterns that can introduce significant bias in the measurement of inflation. I use data collected from credit and debit transactions in the US to update the official basket weights and estimate the impact on the Consumer Price...

How much economic value did the diffusion of broadband create? We provide benchmark estimates for 1999 to 2006. We observe $39 billion of total revenue in Internet access in 2006, with broadband accounting for $28 billion of this total. Depending on the estimate, households generated $20 to $22...
