Textbooks of macroeconomics regularly remind their readers that they should not interpret the macroeconomic price variable as some sort of average price. Instead it represents some price index indicating the average of the individual items' price changes between the period considered and some...

This paper considers the problem of aggregation in the case of large linear dynamic panels, where each micro unit is potentially related to all other micro units, and where micro innovations are allowed to be cross sectionally dependent. Following Pesaran (2003), an optimal aggregate function is...

In this paper, we examine the stochastic structure of a consumer price index and its inflation that ultimately provides the basis for monetary policy and other contracting fulfillments. The index is the broad monthly consumer price index, IPC-A of the Brazilian Institute of Geography and...

The paper explores the extent to which products follow systematic pricing patterns over their life cycle and the impact this has on the measurement of inflation. Using a large US scanner data set on supermarket products and applying flexible regression methods, we find that on average prices...

Lacking data on price levels across locations, economists are forced to proxy them. One method is to extrapolate the price levels known for locations in some point in time to another point by multiplying the initial price levels by the local CPIs. With the use of simulation experiments, this...

This paper evaluates the effects of product turnover on a welfare-based cost-of-living index. We first present some facts about price and quantity changes over the product cycle employing scanner data for Japan for the years 1988-2013, which cover the deflationary period that started in the...

Consumers hold inventory for future uses. This study investigates how such intertemporal decisions influence the cost-of-living index (COLI). To this end, I construct a simple dynamic model, in which goods are storable and nonresalable, and prices take either high (regular price) or low values...

Consumers are very responsive to sales, yet statistical agency practice typically under-weights sale prices in the Consumer Price Index (CPI), with some agencies excluding sale prices completely. Evidence is lacking on how this may impact on both the representativeness of prices included in the...
