This article tests the Fourier flexible form on quarterly U.S. monetary data. The data have been prescreened for consistency with the general axiom of revealed preference, and subindexes are formed using the Divisia approach. In this article, the global Fourier model fits well, although there is...

In this paper we consider and illustrate a solution to the inter-related problems of monetary aggregation and estimation of money demand. The problem with the definition of money is that the relative prices of the monetary components fluctuate over time, rendering simple-sum aggregates...

This paper compares the performance of eight frequently used flexible forms that are either (1) locally flexible, (2) 'effectively globally regular', or (3) asymptotically globally flexible. Results show that the functions with global properties generally perform better, particularly those...
