Computing equilibrium paths of continuous families of economies. By Kose John. Abstract (Thesis) Thesis--University of Florida.(Bibliography) Bibliography: leaves (Statement of Responsibility) by Kose John (Statement of Responsibility) by Kose John Topics: Equilibrium (Economics) -- Mathematical models (lcsh Author: Kose John.

With continuous time, equilibrium paths of prices are smooth; this, even for endowments and discount factors of individuals that do not depend continuously on time. Brown et al. (b) show that traditional homotopy path-following techniques cannot be used to compute an equilibrium for this example, since the path starting at t=0 necessarily must exhibit a discontinuity.

Therefore, the problem of finding an equilibrium for the economy in this example represents a serious test for our algorithm. 2] establish the existence of such a recursive equilibrium under the strong condition that the competitive equilibrium is globally unique for all possible initial values.

Although one can state a similar result for the economies studied here, this strong condition cannot be checked from primitives. Purchase Theory of General Economic Equilibrium - 1st Edition.

Print Book & E-Book. ISBNBook Edition: 1. Equilibrium paths in economies of overlapping generations depend on the frequency of trade. In a logarithmic example, determinacy obtains as the fre-quency of trades tends to infinity or trade occurs in continuous time.

If time extends infinitely into the infinite past as well as into the infinite. A central question in economics and computer science is when and how markets can arrive at an equilibrium. Many existing algorithms for computing equilibria in classes of Arrow-Debreu markets rely.

This concept of computing the path of equilibria is very natural as it is an analogue of market adjustment. These equilibrium paths are central to the study of multiple equilibria, tâtonnement, comparative statics, and market instabilities.

That is to say, if p* is an equilibrium price system of an economy, E0, and if there are two continuous paths connecting E 0 with another economy, E l, and if to each of these paths there corresponds a well-defined continuous path of equilibrium price systems starting at p*, then it may very well happen that the paths lead to completely.

De–nition A competitive equilibrium of the Ramsey economy consists of paths [C (t),K (t),w (t),R (t)]∞ t=0, such that the representative household maximizes its utility given initial capital stock K (0) and the time path of prices [w (t),R (t)]∞ t=0, and all markets clear.

This paper presents some examples of regular dynamic economies with externalities and taxes that either lack existence of a Markov equilibrium or such equilibrium is not continuous.

The equilibrium price and quantity in a market are located at the intersection of the market supply curve and the market demand curve. While it is helpful to see this graphically, it's also important to be able to solve mathematically for the equilibrium price P* and the equilibrium quantity Q* when given specific supply and demand curves.

In computing these welfare gains, careful attention is given to the dynamic path of tax rates and the transitional dynamics associated with how the economy responds to a new tax policy.

This article implements an Augmented Lagrangian algorithm to compute equilibria in a general equilibrium model with incomplete markets and default.

It is one of the first attempts to solve such a model on a large scale. Convergence is found for various economic parameters. We illustrate the effectiveness of this approach for simulating general equilibrium economies with a default.

petitive equilibrium economy: The e¢ ciency of competitive equilibrium The benevolent planner™s problem is shown to be equivalent to the competitive equilibrium in an economy without frictions or distortions, like those introduced by distortionary taxation.

Welfare theorems are shown for such an economic structure. In this section, we build the theoretical foundation for a homotopy algorithm for computing an equilibrium of the economy (E).

For an introduction to homotopy methods, see the book by Garcia and Zangwill (). We introduce a utility maximization problem for each constrained agent i with penalties for transactions on the asset markets. Furthermore, even when for a given specification of the economy equilibrium is globally unique, as Richter and Wong point out, the possibility of multiple equilibria for close-by economies implies that it is generally impossible to compute prices and allocations that are close-by exact equilibrium prices and allocations (as opposed to computing.

This paper is concerned with the existence and computation of general equilibrium with incomplete asset markets and default. Due to the incompleteness. Solves for price and quantity in two product markets when a shift in demand in one generates feedback effects in the other.

There are three classes of demanders or buyers of goods: consumers, firms, and the. Robert C. Mertons widely-used text provides an overview and synthesis of finance theory from the perspective of continuous-time analysis.

It covers individual finance choice, corporate finance, financial intermediation, capital markets, and selected topics on the interface between private and public finance.

Market Equilibrium in Exchange Economies with Some Families of Concave Utility Functions Bruno Codenotti⁄ Kasturi Varadarajany Abstract We consider the problem of computing equilibrium prices for exchange economies.

We tackle this problem under the assumption that the traders have either CES (constant elasticity of sub. consider an equilibrium where the proportion of traditionalists is high. As a consequence, there is little technological change and the environment is stable.

Because of the stability of the environment, the relative benefit of tradition is high, which sustains the high proportion of traditionalists. Thus, such an equilibrium is stable. economic growth under the conditions they identified raises obstacles in its own path and is ultimately retarded, ending in a state of stagnation – the ‘stationary state’.

The conception of the stationary state as the ultimate end of the process of economic growth is often interpreted as a ‘prediction’ of the actual course of economic. In this paper we study algorithms for computing market equilibrium in markets with linear utility functions.

The buyers in the market have an initial endowment given by a portfolio of goods. The market equilibrium problem is to compute a price vector that ensures market clearing, i.e., the demand of a positively priced good equals its supply. Downloadable.

We present a continuous time overlapping generations model for an endowment Arrow-Debreu economy with an age-structured population. For an economy with a balanced growth path, we prove that Arrow-Debreu equilibrium prices exist, and their dynamic properties are age-dependent.

Our model allows for an explicit dependence of prices on critical age-specific endowment parameters.

An algebraic proof is given of the existence of equilibrium points for bimatrix (or two-person, non-zero-sum) games. The proof is constructive, leading to an efficient scheme for computing an equilibrium point.

In a nondegenerate case, the number of equilibrium points is finite and odd. The proof is valid for any ordered field.

"The chapters in this volume address many of the most challenging economic policy issues facing both developed and developing countries and regions. The book is required reading for anyone wishing to understand the power and range of computable general equilibrium modelling as an input to strategy analysis and policy making."Reviews: 2.

This course attempts to explain the role and the importance of the financial system in the global economy. Rather than separating off the financial world from the rest of the economy, financial equilibrium is studied as an extension of economic equilibrium.

The course also gives a picture of the kind of thinking and analysis done by hedge funds.Book I, Chapter II: The Substance of Economics. Book I, Chapter III: Economic Generalizations Or Laws. Book I, Chapter IV: The Order and Aims of Economic Studies.
