Methods by which engineers stabilise their mechanisms suggest analogous possibilities for stabilising economic systems.

Arnold Tustin
Feedback: It is the fundamental principle that underlies all self-regulating systems, not only machines but also the processes of life and the tides of human affairs.

Arnold Tustin
The analysis of engineering systems and the understanding of economic structure have advanced since then, and the time is now more ripe to bring these topics into a potentially fruitful marriage.

Arnold Tustin
When beliefs need some modification, We make it with much trepidation, For our world is then new, And things seem all askew, 'til we're used to the new formulation.

Arnold Tustin
The striking parallel between the economic models that are currently under discussion and some engineering systems suggests the hope that in some way the rapid progress in the development of the theory and practice of automatic control in the world of engineering may contribute to the solution of the economic problems.

Arnold Tustin
Already well known to engineers all over the world as a pioneer in the development of automatic control, it may well turn out that Gordon Brown will make a still deeper mark on the engineering development of this century.

Arnold Tustin
Actual economic systems are constantly subjected to change and disturbances, which would result in irregularity.

Arnold Tustin
The 'theory of control systems' in engineering is now a well-developed subject, making use of some remarkably powerful concepts and methods of analysis, especially in relation to problems of stabilization and the prevention of unwanted oscillations.

Arnold Tustin
The topic that I have attempted to explore is the usefulness of these notions of the engineer, about feeds-back, harmonic components and the like, in application to the analogous problems of economic fluctuation and economic regulation.

Arnold Tustin
He is transported to that curious world of decibels and negative frequencies where filter experts live.

Arnold Tustin
Consideration of a further possibility, namely that of constructing physical systems that are analogues of the economic system, and of observing and recording their behaviour.

Arnold Tustin
Once a full-employment policy has been adopted... the economic 'system' just on that account is significantly different. Its equilibrium position has been shifted to a rising curve of trend close to and following the employment ceiling. The conditions of stability about this new level are radically different because the region of operation is now within the less flexible and sharply non-linear range of employment saturation

Arnold Tustin
The separate excitation of the dynamo corresponds with the independently determined investment in the economic model, and the total excitation with income. Perhaps in this electrical age, the conventional metaphor of 'priming the pump' might be dropped in favour of 'exciting the dynamo'.

Arnold Tustin
An economic system is not a linear system, and... this fact stands in the way of the determination of the parameters of the system by methods that presume linearity, and... it introduces great difficulties in the extrapolation from past behaviour for purposes of prediction.
