摘要：The degree of substitutability of different monetary assets serves as a valuable source of information for Pakistan’s monetary authorities in the context of money demand analysis. Barnett’s (1980) concept of the micro-foundations of money demand has paved the way for a more comprehensive demand system analysis. Locally flexible functional forms are unable to estimate substitution elasticities at all data points, and thus, we use the asymptotically ideal model, which is a semi-nonparametric globally flexible functional form. Our data on income, price, and substitution elasticities show that there is less-than-perfect substitution among monetary assets. The results of Allan and Morishima elasticities show that the former are inherently biased toward showing monetary assets as complements, making Morishima a better choice. The study recommends that it is high time Pakistan’s monetary authorities abandoned the simple-sum aggregation method, which assumes perfect substitution among monetary assets.
