General equilibrium theory is a branch of theoretical microeconomics.
Some of the recent work in general equilibrium has in fact explored the implications of incomplete markets, which is to say an intertemporal economy with uncertainty, where there do not exist sufficiently detailed contracts that would allow agents to fully allocate their consumption and resources through time.
General equilibrium models show what the economy would have to be like for an unregulated economy to be Pareto efficient.

 Nash Equilibrium
A Nash Equilibrium is a set of mixed strategies for finite, non-cooperative games between two or more players whereby no player can improve his or her payoff by changing their strategy.
Other academic theorists used the concept of 'equilibrium' in the 19th century (Maxwell, Walrus, Gibbs), for chemical and economic equilibrium in the early stages of the 20th century (van der Waals, Onnes, Keynes) before Nash used it in the middle of the 20th century.
Equilibrium theory struggles to satisfy academic standards in contemporary social sciences (and economics), which require a double hermeneutical approach (Radder, 2003) in addition to the explanatory method given by the mathematical sciences, by neo-classical economics, and even in the new technological sciences.

 General Equilibrium
To express the equilibrium, the equilibrium constant expression (Kc) is used.
The equilibrium constant expression can be found by multiplying the equilibrium concentrations of the products raised to their coefficient powers and dividing by the equilibrium concentration of the reactants raided to their coefficient powers.
Notice also that the equilibrium constant expression for Equation #2 is the reciprocal of the equilibrium constant expression for Equation #1.

 Hussman Funds - Weekly Market Comment: September 7, 2003 - General Equilibrium
Partial equilibrium allows us to examine the effect of a change in the supply or demand in a given market, on the assumption that other conditions in the economy are held constant.
General equilibrium is why there is no such thing as government stimulus, assuring that fiscal and monetary interventions must always take the form of redistributions and reallocations, which are only stimulative if those policies ease some constraint that is binding.
General equilibrium is why the currency and government securities produced by these reallocations represent not aggregate wealth, but claims of some members of society on the future production of others.

 Differential Approach to General Equilibrium
General equilibrium theory aims at studying the equilibrium price vector as a function of the parameters defining the economy; it describes those states in which the independent plans of many agents with conflicting interests are compatible such a state is called an equilibrium.
The differential approach to general equilibrium theory thus attempts to go beyond the often overstudied existence question, endowing the equilibrium set with a more regular structure and with differentiability assumptions it permits a greater examination of the properties of equilibria that are economically interesting (such as uniqueness).
The approach adopted by Smale to the study of general economic equilibrium was to put the main results of classical general equilibrium theory in a global calculus context.

 Applying General Equilibrium - Cambridge University Press   (Site not responding. Last check: )
The central idea underlying this work is to convert the Walrasian general equilibrium structure (formalized in the 1950s by Kenneth Arrow, Gerard Debreu and others) from an abstract representation of an economy into realistic models of actual economies.
Numerical, empirically based general equilibrium models can then be used to evaluate concrete policy options by specifying production and demand parameters and incorporating data reflective of real economies.
The authors contend that the Walrasian general equilibrium model provides an ideal framework for appraising the effects of policy changes on resource allocation, assessing who gains and who loses, and the policy impacts not well covered by empirical macro models.

Insurance aspects of tax policies are studied in a simple intertemporal general equilibrium model in which agents are uncertain about both the future wage rates and the rate of return on capital.
Taxation and lump-sum subsidy policies generally reduce employment, output, and the capital stock but, nonetheless, they can be structured to provide Pareto improvements on the incomplete market equilibrium.

 Computable general equilibrium models   (Site not responding. Last check: )
Using the methods, which have traditionally been used for transport policy analysis, it is difficult to assess correctly these essentially general equilibrium effects.
However, in recent years advances in the theory and practice of Computable General Equilibrium (CGE) modeling have con-siderably facilitated the quantification of general equilibrium effects.
It is therefore pertinent and timely to consider whether in the context of transport policy analyses the importance of being able to evaluate general equilibrium effects can justify the added complication of using general equilibrium rather than partial equilibrium approaches.

 SSRN-Imperfect Competition, General Equilibrium And Unemployment by Hans Gersbach, Achim Schniewind
We consider a general equilibrium model where firms in one sector compete a la Cournot and a real wage rigidity leads to unemployment.
If firms consider only partial equilibrium effects when choosing quantities, the observation of general equilibrium feedback effects will lead to repeated quantity adjustments until a steady state is reached.
When labor is immobile across industries, unempolyment in the steady state is lower than when all general equilibrium effects are incorporated at once.

 A Primer in Dynamic General Equilibrium Analysis
The appeal of dynamic general equilibrium models for policy simulation is apparent, and yet there exist virtually no systematic introduction to these techniques.
Having defined uncompensated demand functions, we now may characterize the equilibrium conditions in terms of three classes of equations: (i) zero profit conditions for all constant returns activities, (ii) market clearance conditions for all goods and factors, and (iii) income balance equations relating factor income to expenditure.
A disadvantage of the approach is that the added constraint is non-integrable so this method is most useful for dynamic general equilibrium models formulated as complementarity problems.

Uniquely, none of the contributors portray general equilibrium theory as the perfect guide to market economies actual behaviour, but rather illustrate that there is insufficient acquaintance with existing alternatives and that general equilibrium theory is often used as an ideal 'benchmark'.
