The subject of factor indeterminacy has a vast history in factor analysis (Wilson, 1928; Lederman, 1938, Guttman, 1955). It has lead to strong differences in opinion (Steiger, 1979). The current paper gives necessary and sufficient conditions for observability of factors in terms of the parameter matrices and a finite number of variables. Five conditions are given which rigorously define indete...

This paper investigates the consequences of debt stabilization for inflation targeting. If the monetary authority perfectly stabilizes inflation while the fiscal authority holds constant the real value of debt at maturity, the equilibrium dynamics might be indeterminate. However, determinacy can be restored by committing to targeting rules for either monetary or fiscal policy that include a con...

In his paper “Does utility curvature matter for indeterminacy”, Kim (2005) analyzed the relationship among the utility function form, curvature and indeterminacy, concluding that the relationship between curvature and indeterminacy is not robust in neoclassical growth model and the indeterminacy may disappear under the utility specification as in Greenwood et.al (1998). The models he discussed ...

Abstract According to the Determinable Based Account (DBA) of metaphysical indeterminacy (MI), there is MI when an indeterminate state affairs, roughly a affairs in which constituent object x has determinable property but fails have unique determinate that determinable. There are different ways might no determinate: — gappy MI, or more than one determinate— glutty MI. Talk determinables and det...

Triple Refined Indeterminate Neutrosophic Set (TRINS) which is a case of the refined neutrosophic set was introduced in [27]. It provides the additional possibility to represent with sensitivity and accuracy the uncertain, imprecise, incomplete, and inconsistent information which are available in real world. More precision is provided in handling indeterminacy; by classifying indeterminacy (I) ...

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...
