We study how millions of granular and weekly household scanner data combined with machine learning can help to improve the real-time nowcast of German inflation. Our nowcasting exercise targets three hierarchy levels of inflation: individual products, product groups, and headline inflation. At...

We investigate the effect of immigration on consumer prices in Spain between 1997 and 2013. Using variation across provinces, we first document a positive correlation between consumer prices and the share of migrants in the population. However, controlling for regional supply and demand shocks,...

The post‑pandemic period in the European Union is distinguished by the growth of business economic activity after two years of restrictions, growing debts and money supply, and extremely high inflation. This research analyses the Harmonised Index of Consumer Prices (HICP) in the service...

This paper examines the long-run relationship between consumer price index industrial workers (CPI-IW) inflation and GDP growth in India. We collect data on a sample of 14 Indian states over the period 1989-2013, and use the cross-sectionally augmented distributed lag (CSDL)approach of Chudik et...

A growing literature examines the effects of economic variables on obesity, typically focusing on only one or a few factors at a time. We build a more comprehensive economic model of body weight, combining the 1990-2010 Behavioral Risk Factor Surveillance System with 27 state-level variables...

No cross-sectional consumer price index is currently available by state, and the BLS's cross-sectional "family budget" index for metropolitan areas is not well-suited for cross-state analyses. In this paper we propose an algorithm for constructing a state-specific Laspeyres price index using...

This paper analyzes the long-run determinants of inflation differentials in a monetary union. First, we aim at establishingsome stylized facts relating the regional dispersion in headline inflation rates in the euro area as well as in the main components of the consumer price index. We find that...

Cellular telephone is an example of a new product that has significantly affected how Americans live. Since their introduction in 1983, cellular telephone adoption has grown at 25-35% per year such that at year end 1996 about 42 million cellular telephones are in use in the U.S. However,...

Inaccurate measures of the aggregate price level may distort short-run policy decisions and may produce misleading comparisons of productivity growth across decades and among nations. This paper serves a dual purpose of reviewing compactly the vast American literature on price and output...
