In aggregation theory, index numbers are judged relative to their ability to track the exact aggregator functions nested within the economy's structure. Within the monetary sector, Barnett, Liu, and Jensen (1997) compared two statistical index numbers: the Divisia monetary aggregate and the...

A current U.S. policy is to introduce a new style of currency that is harder to counterfeit, but not immediately to withdrawal from circulation all of the old-style currency. This policy is analyzed in a random-matching model of money, and its potential to decrease counterfeiting in the long run...

We measure the United States capital stock of money implied by the Divisia monetary aggregate service flow, in a manner consistent with the present-value model of economic capital stock. We permit non-martingale expectations and time varying discount rates. Based on Barnett’s (1991) definition...

This paper is a comment on Serletis and Shintani, 'Chaotic Monetary Dynamics with Confidence,' which is to appear in a special issue of the Journal of Macroeconomics on chaos in economics. The Editor of the special issue invited comments from discussants of all papers in the special issue, with...

Euler equation models represent an important class of macroeconomic systems. Our research on the Leeper and Sims Euler equations macroeconomic model reveals the existence of singularity-induced bifurcations, when the model's parameters are within a confidence region about the parameter...

This is the front matter from the book, William A. Barnett and Apostolos Serletis (eds.), The Theory of Monetary Aggregation, published in 2000 by Elsevier in its Contributions to Economic Anaysis mongraph series. The front matter includes the Table of Contents and the Introduction by Barnett...

This entry on monetary aggregation will appear under that title in The New Palgrave Dictionary of Economics, 2nd edition, edited by Steven Durlauf and Lawrence Blume. The entry provides an up-to-date overview of state-of-the-art research on monetary aggregation and index number theory, from its...

We design a procedure for measuring the United States capital stock of money implied by the Divisia monetary aggregate service flow, in a manner consistent with the present-value model of economic capital stock. We permit non-martingale expectations and time varying discount rates. Based on...

Modern aggregation theory and index number theory were introduced into monetary economics by Barnett (1980). The widely used Divisia monetary aggregates were based upon that paper. A key result upon which the rest of the theory depended was Barnett’s derivation of the user-cost price of...

This paper is a follow-on to our earlier paper, "Bifurcations in Continuous-Time Macroeconomic Systems." In this paper, we determine the stability properties of the UK continuous time macroeconometric model on its bifurcation boundaries and we test the null hypothesis that the model's parameters...
