Interest has been growing in testing for nonlinearity or chaos in economic data, but much controversy has arisen about the available results. This paper explores the reasons for these empirical difficulties. We designed and ran a single-blind controlled competition among five highly regarded...

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...

I have been invited to write an essay on my experiences as founder and editor of the Cambridge University Press journal, Macroeconomic Dynamics. I have decided to focus the essay on my experiences in starting up the journal. Few economists, who have not themselves started up a new journal, are...

While credit cards provide transaction services, as do currency and demand deposits, credit cards have never been included in measures of the money supply. The reason is accounting conventions, which do not permit adding liabilities, such as credit card balances, to assets, such as money. But...

This survey provides an overview of the classes of macroeconometric models for which these experiments have so far been run and emphasizes the implications for lack of robustness of conventional dynamical inferences from macroeconometric policy simulations. By making this detailed survey of past...

This paper constructs and analyzes core inflation indicators for Saudi Arabia for the period of March 2012 to May 2014 using two alternative approaches: the Exclusion Method (ex food and housing/rent) and the Statistical Method. The findings of the analysis suggest that the ex food and...

This paper builds monthly time-series of Divisia monetary aggregates for the Gulf area for the period of June 2004 to December 2011, using area-wide data. We also offer an "economic stability" indicator for the GCC area by analyzing the dynamics pertaining to certain variables such as the dual...

This paper explores the conceptual links between Joseph Schumpeter’s theory of instability under capitalism and both theoretical and empirical research that has been done over the past fifteen years in nonlinear dynamics. Recent work related to chaos and bifurcation theory is shown to be...
