We present the first ex post study that quantitatively analyses the effects of a licence buy-back and enhanced quota trading on the profitability and productivity of individual vessels in a fishery. Using firm-level data and a profit index decomposition method, we find that small and large...

In this paper, we measure the main factors explaining nominal output growth and deviations from trend output in Switzerland over the period 1980 to 2001. The decompositions are based on the GDP function and its dual, the national income function. The results indicate that whereas nominal output...

We examine the impact of time aggregation on price change estimates for 19 supermarket item categories using scanner data. Time aggregation choices lead to a difference in price change estimates for chained indexes which ranged from 0.28% to 29.73% for a superlative index and an incredible...

Patterns of trade have changed enormously over the last 30 years, particularly due to the economic emergence of several Asian countries. With the increasing international tendency for bilateral preferential trade agreements, it is important for countries to be aware of trade substitution...

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...
