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...

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...

This paper uses the Fourier flexible form to jointly approximate utility and service flows from durable and nondurable goods. In contrast, parametric functions are usually not flexible enough to accurately approximate nonseparability and often give inconsistent results. This paper calls these...
