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...

We estimate the dynamic Fourier expenditure system to obtain consistent estimates of short-run and long-run Morishima elasticities of substitution for Canadian liquid assets. We argue that the variability of the estimated elasticities and evidence of less than perfect substitution between...
