For previously identified weakly separable blockings of goods and assets, we construct aggregates using four superlative index numbers, the Fisher, Sato-Vartia, Törnqvist and Walsh, two non-superlative indexes, the Laspeyres and Paasche and the atheoretical simple summation. We conduct several...

In this paper, we take stock of how statistical agencies in different nations are currently accounting for housing in their consumer price indexes (CPIs). The rental equivalence and user cost approaches have been favorites of economists. Both can be derived from the fundamental equation of...

The Hamilton method for estimating CPI bias is simple, intuitive, and has been widely adopted. We show that the method confiates CPI bias with variation in cost-of-living across income levels. Assuming a single price index across the income distribution is inconsistent with the downward sloping...

This paper introduces a new approach for studying behaviour in information networks. Index number theory, which has been developed in the context of comparing income and prices across countries, regions or over time, is used to derive indexes of information consumption. In particular, we...

We provide an innovative methodological contribution to the measurement of returns on infrequently traded assets using a novel approach to repeat-sales regression estimation. The model for price indices we propose allows for correlation with other markets, typically with higher liquidity and...

In Germany, package holidays are an important driver of consumer prices. Several challenges arise when measuring the price development of these bundled travel and accommodation services, such as the quality of accommodation and the timing of booking. Statistical practices are currently based on...

In Germany, package holidays, which consist of a bundle of flight and accommodation services, are an important driver of consumer prices. Several challenges arise when measuring the price development of package holidays, for example the quality of accommodation, the timing of the booking, the...

The big bang of non-fungible tokens (NFTs) has caused the birth of a brand new era for digital art. NFTs, driven by blockchain and smart contracts, provide both artists and art collectors an unprece- dented marketplace equipped with more security, flexibility, publicity, and freedom to monetize....

This paper shows that the decomposition of log-change in aggregate labor productivity (ALP) devised by Balk (2013) based on Sato-Vartia indexes is inexact when applied to gross domestic product (GDP) in chained or in constant prices so that sectoral contributions do not necessarily add up to...
