To make the argument that the behaviour of modern industrial economies since the 1990s is inconsistent with theories in which there is a unique ergodic macro equilibrium, the paper starts by reviewing both the early Keynesian theory in which there was no unique level of income to which the...

One of the most neglected issues in modern economics concerns the consequences of technological change that is ubiquitous and endogenous. To address these we need to model technology as more than a scalar value in an aggregate production function, dealing with technological change in its messy...

This paper discusses twenty five methodological issues covering selected areas of both micro and macroeconomics. Included on the micro side are issues related to modelling the price system, assessing its efficiency, competing models of competition, modelling technological change and economic...

The theory of second best established that the effect on community welfare of any one policy change varies with the specific context in which that change occurs. In paper that has been frequently quoted to justify specific policies, Ng argues that fulfilling firstbest conditions piecemeal is an...

The model incorporates characteristics of general purpose technologies established empirically but not currently modeled: GPTs occur simultaneously in several technology "classes," such as ICTs and materials; different "versions" of each class often compete with each other; GPTs of different...

We assess the contention that the force of the ICT revolution was spent when the dotcom bubble burst. We identify the fundamental principle of flexible machine logic, the use of which distinguishes the group of modern ICTs - the electronic computer, the Internet and some related technologies -...

This is a unique account of the role played by 58 figures and diagrams commonly used in economic theory. These cover a large part of mainstream economic analysis, both microeconomics and macroeconomics and also general equilibrium theory.

We ask if pure profits obtained in our earlier model might be dissipated by forces excluded. We consider the possibility that the profits will be converted into land rents and usurped by landlords and conclude this will not happen. Second, we consider new firms entering to drive existing firms...

We consider Gee's model of industrial location and prove analytically that, given Gee's assumption of price discrimination, firms always wish to locate in the centres of their markets. This contrasts the result for mill-price-plus-transport-cost pricing where firm locate in the centres of...

We argue that the effectiveness of capital as an entry barrier depends critically on its durability and that this aspect of capital has been largely ignored. We examine strategic decisions with respect to capital durability in two models. In a broad range of cases an active policy with respect...
