Abstract Do the dynamics of a physical system determine what function computes? Except in special cases, answer is no: it often indeterminate given computes. Accordingly, care should be taken when question ‘What does particular neuronal do?’ answered by hypothesising that computes function. The phenomenon indeterminacy computation has important implications for development computational explana...

Can consumption externalities be a source of indeterminacy? The answer is negative in conventional wisdom. In this paper we show that consumption externalities establish local indeterminacy if the degree of decreasing impatience is sufficiently large. Dynamic models with indeterminacy are valuable as they tend to explain economic fluctuations without relying on exogenous shocks and question int...

‘Material indeterminacy’ is the term I use to discuss how my work since 2010 has explored consequences of placing materiality, indeterminacy, and responsiveness at centre a compositional practice, what means for relationships between instrument, player, score. propose that structural consequence contingency in instrumental performance an underexplored aspect experimental composition, which hist...

This paper studies the possibility that a “catching-up-with-the-Joneses” effect can cause indeterminacy. In an otherwise standard growth model with an external past consumption habit, we analytically show that a catching-up-with-the-Joneses effect is a possible source of indeterminacy. In the quantitative investigation, we use a calibrated version of the model with a CES utility and find that i...

In this article consumers need money to reduce their transaction costs. We highlight the existence of indeterminacy under a constant money growth within an endogenous growth framework. Real indeterminacy is avoided by an alternative monetary policy such as the interest pegging. The residual price indeterminacy is also ruled out if this monetary policy is completed by a non-Ricardian ...scal pol...

We study the interaction of multiple large economies in dynamic stochastic general equilibrium. Each economy has a monetary policymaker that attempts to control the economy through the use of a linear nominal interest rate feedback rule. We show how the determinacy of worldwide equilibrium depends on the joint behavior of policymakers worldwide. We also show how indeterminacy exposes all econom...
