This paper analyzes how the indeterminacy of competitive equilibrium in one-sector growth models depends on the magnitude of the households’income e¤ect on the demand for leisure. The paper …rst establishes that the presence of income e¤ect is necessary for the existence of an indeterminate equilibrium. Because I am further interested in quantitatively characterizing regions of uniqueness and r...

This essay discusses work on the determinacy and indeterminacy of equilibrium in models of competitive markets. Determinacy typically refers to situations in which equilibria are finite in number, and local comparative statics can be precisely described. This essay describes basic results on generic determinacy for exchange economies and the general underlying principles, together with various ...

A dynamic approach is proposed for the analysis of the Cournot oligopoly game with hyperbolic demand, showing that the adoption of capital accumulation dynamics either à la Solow-Swan or à la Ramsey eliminate the indeterminacy problem characterising the static model when marginal costs are nil. It is proved that the steady state equilibria produced by both models are stable in the saddle point ...

We study the relation between capital accumulation, fiscal policy, and sovereign debt dynamics in a small open economy. The government maximizes spending, facing borrowing constraints conditionality requirement. Debt are forward looking, being driven by endogenous constraint. Current is determined expectations about government's ability to finance itself future, opening room for indeterminacy. ...

Indeterminacy makes the main distinction between fuzzy/intuitionistic fuzzy (and other extensions of fuzzy) set/logic vs. neutrosophic set/logic, and classical probability probability. Also, statistics plithogenic statistics, algebraic structures structures, crisp numbers numbers. We present a broad definition indeterminacy, various types indeterminacies, many practical applications.

Uncertainty and indeterminacy are two major problems in data analysis these days. Neutrosophy is a generalization of the fuzzy theory. Neutrosophic system is based on indeterminism and falsity of concepts in addition to truth degrees. Any neutrosophy variable or concept is defined by membership, indeterminacy and non-membership functions. Finding efficient and accurate definition for neutrosoph...
