conclusions on the overall GARP-consistency of data and on weak separability of particular aggregates are affected by the …

Using non-parametric weak separability tests that are extended to allow for measurement errors in the data, a broad …

Weak separability is an important concept in many fields of economic theory. This paper uses Monte Carlo experiments to … investigate the performance of newly developed nonparametric revealed preference tests for weak separability. A main finding is … that the bias of the sequentially implemented test for weak separability proposed by Fleissig and Whitney (A New PC …

Two stochastic nonparametric procedures are developed to evaluate the significance of violations of weak separability …. When the data have measurement error, we show that the necessary and sufficient weak separability conditions of Varian … Afriat inequalities. The tests detect weak separability with high probability for weakly separable data. In addition, the …

In the estimation of aggregate meat demand systems, weak separability is often a maintained assumption. However, only a … commodity theorem (GCCT) that is less restrictive than weak separability. In this study, a data set in which the weak … separability conditions for aggregation have been rejected is reconsidered to determine if aggregation can be based on the GCCT …

In this paper we propose a unified framework for testing weak separability. We present a new three-step procedure …

This paper tests the weak separability of the assets in the Bank of England's household-sector Divisia index from 1977Q … necessary and sufficient conditions for weak separability, allows for incomplete adjustment of expenditure on monetary services …
