Consumer-related policy decisions often require analysis of aggregate responses or mean elasticities. However, in practice these mean elasticities are seldom used. Mean elasticities can be approximated using aggregate data, but that introduces aggregation bias for full and compensated price...

“Which index formula at the elementary level, where no expenditure share weights are available, corresponds to a desired aggregate index?” To answer this question, this paper develops a statistical approach. It proposes a theoretical framework which makes it possible to achieve numerical...

This paper sets out a general algorithm for calculating true cost-of-living indices or true producer price indices when demand is not homothetic, i.e. when not all expenditure elasticities are equal to one. In principle, economic theory tells us how we should calculate a true cost-of-living...

Policy analysis frequently requires estimates of aggregate (or mean) consumer elasticities. However, estimates are often made incorrectly, based on elasticity calculations at mean income. We provide in this paper an overall integrated analytical framework that encompasses these biases and...

We propose a method for constructing price indices when retailers use periodic sales to price-discriminate amongst heterogeneous customers. To do so, we introduce a model in which Loyal customers buy one brand and do not strategically time purchases, while Bargain Hunters always pay the lowest...

We show that in a unit demand discrete choice framework with at least three goods, demand cannot be additively separable in own price. This result sharpens the analogous result of Jaffe and Weyl (2010) in the case of linear demand and has implications for testing of the discrete choice...

The Boskin report (1996) concluded that the US consumer price index (CPI) overestimated the inflation by 1.1 percentage points. This was due to several measurement errors in the CPI. One of them is called quality change bias. We compare two methods in this paper which can be used to correct for...

This paper analyses the transmission of financial shocks to the macroeconomy. The role of macro-financial linkages is investigated from an empirical perspective for the euro area as a whole, for individual euro area member countries and for other EU and OECD countries. The following key economic...

This work focuses on the development of house price indices for Nigeria, and the estimates of the Nigerian Residential Property Price Indices on housing characteristics are presented. Four main methods of index construction were considered, these are hedonic regression, repeat-sales,...
