The quasi-linear fuzzy modelling of Filev (1991) is used to estimate the relationship between the number of managers and employees in a firm. The results form the basis for the classification of firms into small and large businesses. Application to a data of Australian firms shows an evolution...

This paper sheds new light on forces shaping the outsourcing decision by linking the decision to a certain form of non-linearity in overhead costs which divides a firm’s operation into small and large regimes. Marginal firms that find evolution into a large business too costly outsource in a...

This paper sheds new light on the forces shaping outsourcing decision by considering a certain form of non-linearity in overhead costs which effectively discretizes a firm’s size into small and large regimes. Extending Grossman & Helpman (2002) in this line shows that firms unable to fully...

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...

The paper considers some of the problems associated with the indirectly measured components of financial service outputs in the System of National Accounts (SNA), termed FISIM (Financial Intermediation Services Indirectly Measured). The paper utilizes a user cost and supplier benefit approach to...

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...

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...
