regional integration appears to have displaced the multilateral process as a means of liberalising trade in the world economy. Does the pursuit of regional agreements undermine the multilateral process of trade liberalisation embodied in the GATT? In this paper we develop a theoretical framework...

It is common for comparisons to be made of output growth and inflation across groups of countries, yet such comparisons can result in inconsistencies. We address two problems: (i) how to measure aggregate real output and inflation for groups of countries and (ii) how to construct measures of...

Indexes often incorporate various biases due to their methods of construction. The Constant Elasticity of Substitution (CES) index can potentially eliminate substitution bias without needing current period expenditure data. The CES index requires an elasticity parameter. We derive a system of...

The empirical literature on price indices consistently finds that aggregation methods have a considerable impact, particularly when scanner data are used. This paper outlines a novel approach to test for the homogeneity of goods and hence for the appropriateness of aggregation. A hedonic...

Chaining is used in index number construction to update weights and link new items into an index. However, chained indexes can suffer from, sometimes substantial, drift. The Consumer Price Index Manual (ILO, 2004) recommends the use of dissimilarity indexes to determine when chaining is...

Caves, Christensen, Diewert introduced Malmquist output, input and productivity indexes into production theory in a systematic way. This paper revisits the debate on how to decompose Bjurek’s concept of a Malmquist productivity index into explanatory factors, with a focus on extracting...

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 exible regression methods, we find that on average prices...

Departures of the housing market from equilibrium can be detected by comparing the actual price-rent ratio with the user cost of owner occupying. Empirical implementation of this idea, however, is problematic for two reasons. First, the price-rent ratio needs to be quality adjusted. Second, the...

In a contribution to the sparse literature on the impacts on consumers of quarantine restrictions, an innovative approach to analysing the effects of these policies on the prices and quality of imported products is proposed. Specifically, various index num- ber decompositions at different...

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...
