Determinacy and Indeterminacy of Equilibria Abstract 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 basicFile Size: KB.

They face a nonlinear income tax schedule and can engage in tax evasion. Money serves two purposes: the traditional one, modeled through a money-in-the-utility-function, and to facilitate tax evasion. It shows that.

In this article, we propose a formal proof of the local determinacy of prices in a continuous-time, overlapping generations exchange economy. 1 It has been shown with models in discrete time that the equilibrium may be indeterminate and that the degree of indeterminacy may increase with the dimension of the model.

Habit formation and indeterminacy in overlapping generations models Article in Economic Theory 55(1) January with 20 Reads How we measure 'reads'Author: Fabrizio Orrego. I introduce habit formation into an otherwise standard overlapping generations economy with pure exchange populated by three-period-lived agents.

Habits are modeled in such a way that current consumption increases the marginal utility of future consumption. With logarithmic utility functions, I demonstrate that habit formation gives rise to stable monetary steady states in economies with hump Cited by: 2.

Balasko, Yves & Shell, Karl, " The overlapping-generations model. Models of dynamic indeterminacy The indeterminacy agenda in macroeconomics has gone through two phases.

The initial phase, developed at the University of Pennsylvania in the United States and at CEPREMAP in France, consisted of dynamic models driven by. The overlapping generations (OLG) model is one of the dominating frameworks of analysis in the study of macroeconomic dynamics and economic contrast, to the Ramsey–Cass–Koopmans neoclassical growth model in which individuals are infinitely-lived, in the OLG model individuals live a finite length of time, long enough to overlap with at least one period of another agent's life.

This book is a competent textbook on the basics of General Equilibrium and Overlapping Generations models. It is adequate for graduate and undergraduate students of economics.

But is it simply put, boring and takes too much time and examples to teach GE by: Section 6 uses an overlapping generations model to place the two-period model in a dynamic setting. I show that the steady-state equilibria are determinate generically (echo-ing Kehoe and Levine's () study of the pure exchange case), thus demonstrating that constant relative prices preclude indeterminacy.

Also, we will see that the endowment. 1 Indeterminacy and suboptimality in a simple OLG model In this section we analyse the equilibrium set of a one-commodity per period, overlapping generations (OLG) economy, assuming that all agents meet simultaneously in all markets before time begins, just as in the Arrow–Debreu model.

They showed that dynamics depend on the relative necessities of current and future consumption. In. Growth with Overlapping Generations In many situations, the assumption of a representative household is not appropriate because 1 households do not have an in–nite planning horizon 2 new households arrive (or are born) over time.

Indeterminacy, in philosophy, can refer both to common scientific and mathematical concepts of uncertainty and their implications and to another kind of indeterminacy deriving from the nature of definition or meaning.

Prices are all. Chapter 4 Models of Overlapping Generations The representative household model is based on the assumption that all households are identical. An alternative class of models allows for households to differ. As young households are being born and old households die, there is a succession of overlapping generations.

The indeterminacy claim for competitive price systems made by Sraffa () is examined by placing Sraffa's work in an intertemporal general equilibrium model. We show that indeterminacy occurs at a natural type of equilibrium. Moreover, the presence of linear activities instead of a differentiate technology is crucial and the indeterminacy is constructed, as in Sraffa, by fixing some or all.
