Specialty Definition: Chemical equilibrium

(From Wikipedia, the free Encyclopedia)

Chemical equilibrium is the state in which a chemical reaction proceeds at the same rate as its reverse reaction. When this condition is met, there is no change in the proportions of the various compounds involved, and the reaction ceases to progress. A common example given is the Haber-Bosch process, in which hydrogen and nitrogen combine to form ammonia. Equilibrium is reached when the rate of production of ammonia equals its rate of decomposition. Le Chatelier's principle describes qualitative predictions that can be made about chemical equilibrium.

Without energy input chemical reactions always proceed towards equilibrium. For a reaction

equilibrium occurs when

where K is a constant called the equilibrium constant. The left side of the equation is called the mass action expression and is denoted Q for a generic state (not necessarily in equilibrium). For a single-step reaction, this can easily be derived just by considering the kinetics involved. Unlike rate equations, though, it still holds for multi-step reactions since the expressions for each step just multiply together. This, by the way, also gives us the relationship between equilibrium and temperature:

where ΔE is the difference in energy per mole between reactants and products, e is the base of the natural logarithm, and R is the molar gas constant. The constant is mainly influenced by entropy change, but that's a little more complicated - whereas energy is roughly constant against concentration, entropy varies logarithmically so we have to refer back to a particular state. The relationship makes the most sense in terms of the free energy difference, ΔF* = ΔE - TΔS*, which represents the total work that can be done by the system as it develops. At equilibrium ΔF = 0, which gives us

Very often we consider the standard state, where Q = 1 in appropriate units, which can then be neglected. Note that all this applies to a reaction at constant temperature only. For a reaction at constant pressure (which is actually somewhat more typical) you would use the Gibbs free energy, ΔG* = ΔH - TΔS*, where ΔH is the change in enthalpy.

Economic equilibrium

(From Wikipedia, the free Encyclopedia)

In economics where the supply for a certain product matches the demand then economic equilibrium is said to exist, see Supply and demand.

Classical economists such as Adam Smith maintained that the free market would tend towards economic equilibrium through the price mechanism.

This view came under attack from two opposite viewpoints. Socialists, especially Marxists claimed that equilibrium would not come about through the free market as it was chronically unfair and so would always be in disequilibrium. Equilibrium could only be found through central planning.

On the other hand the Austrian School maintained that in the short term there would never be any equilibrium as everyone was always trying to take advantage of the pricing system and so there was always some dynamism in the system. The free market's strength was not fixing a general equilibrium but in organising resources to meet individual desires and discovering the best methods to carry the economy forward.

Equilibrium

(From Wikipedia, the free Encyclopedia)

Equilibrium or balance is any of a number of related concepts in the sciences and social sciences. In general, a system is said to be in a state of equilibrium if all influences on the system are cancelled by the effects of others. A related concept is stability; an equilibrium may or may not be stable.

Some specific examples are:

An addiction is any of various forms of unbalanced behavior.

In electricity, a balanced signal is also called a differential signal.

Equilibrium (2002 movie)

(From Wikipedia, the free Encyclopedia)

Equilibrium is an action-filled science-fiction film set in the future. Christian Bale, Sean Bean and Taye Diggs star in it as ninja-esque secret police officers for a totalitarian one-world government where war and strife are eradicated at the price of making emotion illegal -- similarities to classic dystopian novels such as Nineteen Eighty-Four and Brave New World are evident.

Gun Kata is a fictitious martial arts discipline that features as part of the film. Gun Kata is based upon the premise that the positions and actions of antagonists can be predicted to a high degree of accuracy in any given combat situation.

General equilibrium

(From Wikipedia, the free Encyclopedia)

General equilibrium theory is a branch of theoretical microeconomics. It seeks to explain production, consumption and prices in a whole economy. This article considers neoclassical approaches to general equilibrium. Investigations into the interaction of markets arguably outside of neoclassical theory are taken to be outside the scope of this article. In particular, Classical and Marxist analyses of natural prices or prices of production, Wassily Leontief's Input-Output analysis, and John von Neumann's Linear Programming model of growth are not otherwise discussed.

General equilibrium tries to give an understanding of the whole economy using a bottom-up approach, starting with individual markets and agents. Macroeconomics, as developed by so-called Keynesian economists, uses a top-down approach where the analysis starts with larger aggregates. Since modern macroeconomics has emphasized microeconomic foundations, this distinction has been slightly blurred. However, many macroeconomic models simply have a 'goods market' and study its interaction with for instance the financial market. General equilibrium models typically model a multitude of different goods markets. Modern general equilibrium models are typically complex and require computers to help with numerical solutions.

Under capitalism, the prices and production of all goods are interrelated. A change in the price of one good, say bread, may affect another price, for example, the wages of bakers. If bakers differ in tastes from others, the demand for bread might be affected by a change in bakers' wages, with a consequent effect on the price of bread. Calculating the equilibrium price of just one good, in theory, requires an analysis that accounts for all of the millions of different goods that are available.

History of General Equilibrium Modeling

The first attempt in Neoclassical economics to model prices for a whole economy was made by Leon Walras. Walras' Elements of Pure Economics provides a succession of models, each taking into account more aspects of a real economy (two commodities, many commodities, production, growth, money). Many think Walras was unsuccessful and the later models in this series inconsistent. Nevertheless, Walras first laid down a research program much followed by 20th century economists. In particular, Walras' agenda included the investigation of when equilibria are unique and stable.

Walras also first introduced a restriction into general equilibrium theory that some think has never been overcome, that of the tatonnement or groping process. The tatonnement process is a tool for investigating stability of equilibria. Prices are cried, and agents register how much of each good they would like to offer (supply) or purchase (demand). No transactions and no production take place at disequilibrium prices. Instead, prices are lowered for goods with positive prices and excess supply. Prices are raised for goods with excess demand. The question for the mathematician is under what conditions such a process will terminate in equilibrium in which demand equates to supply for goods with positive prices and demand does not exceed supply for goods with a price of zero. Walras was not able to provide a definitive answer to this question.

In partial equilibrium analysis, the determination of the price of a good is simplified by just looking at the price of one good, and assuming that the prices of all other goods remain constant. The Marshallian theory of supply and demand is an example of partial equilibrium analysis. Partial equilibrium analysis is adequate when the first-order effects of a shift in, say, the demand curve do not shift the supply curve. Anglo-American economists became more interested in general equilibrium in the late 1920s and 1930s after Piero Sraffa's demonstration that Marshallian economists cannot account for the forces thought to account for the upward-slope of the supply curve for a consumer good.

If an industry uses little of a factor of production, a small increase in the output of that industry will not bid the price of that factor up. To a first order approximation, firms in the industry will not experience decreasing costs and the industry supply curves will not slope up. If an uses an appreciable amount of that factor of production, an increase in the output of that industry will exhibit increasing costs. But such a factor is likely to be used in substitutes for the industry's product, and an increased price of that factor will have effects on the supply of those substitutes. Consequently, the first order effects of a shift in the supply curve of the original industry under these assumptions include a shift in the original industry's demand curve. General equilibrium is designed to investigate such interactions between markets.

Continential European economists made important advances in the 1930s. Walras' proofs of the existence of general equilibrium often were based on the counting of equations and variables. Such arguments are inadequate for non-linear systems of equations and do not imply that equilibrium prices and quantities cannot be negative, a meaningless solution for his models. The replacement of certain equations by inequalities and the use of more rigorous mathematics improved general equilibrium modeling.

Modern Concept of general equilibrium in economics

The modern conception of general equilibrium is provided by a model developed jointly by Kenneth Arrow and Gerard Debreu in the 1950s. Gerard Debreu presents this model in Theory of Value (1959) as an axiomatic model, following the style of mathematics promoted by Bourbaki. In such an approach, the interpretation of the terms in the theory (e.g., goods, prices) are not fixed by the axioms.

Three important theorems have been proved in this framework. First, existence theorems show that equilibria exist under certain abstract conditions. The first fundamental theorem of welfare states that every market equilibrium is Pareto optimal under certain conditions. The second fundamental theorem of welfare states that every Pareto optimum is supported by a price system, again under certain conditions. These conditions were stated in the language of mathematical topology. The proofs used such concepts as seperating hyperplanes and fixed point theorems.

Three important interpretations of the terms of the theory have been often cited. First, supposed commodities are distinguished by the location where they are delivered. Then the Arrow-Debreu model is a spatial model of, for example, international trade.

Second, suppose commodities are distinguished by when they are delivered. That is, suppose all markets equilibriate at some initial instant of time. Agents in the model purchase and sell contracts, where a contract specifies, for example, a good to be delivered and the date at which it is to be delivered. The Arrow-Debreu model of intertemporal equilibrium contains forward markets for all goods at all dates. No markets exist at any future dates.

Third, suppose contracts specify states of nature which affect whether or not a commodity is to be delivered: "A contract for the transfer of a commodity now specifies, in addition to its physical properties, its location and its date, an event on the occurrence of which the transfer is conditional. This new definition of a commodity allows one to obtain a theory of [risk] free from any probability concept..." (Debreu 1959)

These interpretations can be combined. So the complete Arrow-Debreu model can be said to apply when goods are identified by when they are to be delivered, where they are to be delivered, and under what circumstances they are to be delivered, as well as their intrinsic nature. So there would be a complete set of prices for contracts such as "1 ton of Winter red wheat, delivered on 3rd of January in Minneapolis, if there is a hurricane in Florida during December". A general equilibrium model with complete markets of this sort seems to be a long way from describing the workings of real economies.

Unresolved problems in general equilibrium

Research building on the Arrow-Debreu model has revealed some problems with the model. The Sonnenschein-Mantel-Debreu results show that, essentially, any restrictions on the shape of excess demand functions are essentially arbitrary. Some think this implies that the Arrow-Debreu model lacks empirical content. At any rate, Arrow-Debreu equilibria cannot be expected to be unique, stable, or determinate.

A model organized around the tatonnnement process has been said to be a model of a centrally planned economy, not a decentralized market economy. Some research has tried, not very successfully, to develop general equibrium models with other processes. In particular, some economists have developed models in which agents can trade at out-of-equilibrium prices and such trades can affect the equilibria to which the economy tends. Particularly noteworthy are the Hahn process, the Edgeworth process, and the Fisher process.

The Arrow-Debreu model of intertemporal equilibrium, in which forward markets exist at the initial instant for goods to be delivered at each future point in time, can be transformed into a model of sequences of temporary equilibrium. Sequences of temporary equilibrium contain spot markets at each point in time. Roy Radner found that in order for equilibria to exist in such models, agents (e.g., firms and consumers) must have unlimited computational capabilities.

Although the Arrow-Debreu model is set out in terms of some arbitrary numeraire, the model does not encompass money. Frank Hahn, for example, has investigated whether general equilibrium models can be developed in which money enters in some essential way. The (unsatisfied) goal is to find models in which whether or not money exists alters equilibrium solutions, perhaps because the initial position of agents depends on monetary prices, for example, when they have debts.

Some critics of general equilibrium modeling contend that much research in these models constitutes exercises in pure matheamtics with no connection to actual economies. "There are endeavors that now pass for the most desirable kind of economic contributions although they are just plain mathematical exercises, not only without any economic substance but also without any mathematical value" (Nicholas Georgescu-Roegen 1979). Georescu-Roegen cites as an example a paper that assumed more traders than there are points on a real line.

Although modern models in general equilibrium theory demonstrate that under certain circumstances prices will indeed converge to equilibria, critics hold that the assumptions necessary for these results are completely unrealistic. The necessary assumptions include perfect rationality of individuals; complete information about all prices both now and in the future; and the conditions necessary for perfect competition.

Frank Hahn defends general equilibrium modeling on the grounds that it provides a negative function. General equilibrium models show what the economy would have to be like for an unregulated economy to be Pareto efficient. Note that Hahn's defense drops any claim that general equilibrium models describe actual capitalist economies.

Some economists reject equilibrium theory outright in favour of more pragmatic models based more closely on observation of the economy.

Nash equilibrium

(From Wikipedia, the free Encyclopedia)

The Nash equilibrium is a concept in game theory originated by John Nash, who was awarded the The Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel, effectively the Nobel Prize in economics, for his work in the area. It serves to define a kind of "optimum" strategy for games where no such optimum was previously defined. A basic definition is this: If there is a set of strategies for a game with the property that no player can benefit by changing his strategy while the other players keep their strategies unchanged, then that set of strategies and the corresponding payoffs constitute a Nash equilibrium.

This definition applies to games of two or more players, and Nash showed that the various definitions of "solutions" for games that had been given earlier all yield Nash equilibria.

As a simple example, consider the following two-player game: both players simultaneously choose a whole number between 0 and 10, inclusive. Both players then win the minimum of the two numbers in dollars. In addition, if one player chose a larger number than the other, then he has to pay $2 to the other. This game has a unique Nash equilibrium: both players have to choose 0. Any other choice of strategies can be improved if one of the players lowers his number. If the game is modified so that the two players win the named amount if they both choose the same number, and otherwise win nothing, then there are 11 Nash equilibria.

If a game has a unique Nash equilibrium and is played among completely rational players, then the players will choose the strategies that form the equilibrium.

A game may have many Nash equilibria, or none. Nash was able to prove that, if we allow mixed strategies (players choose strategies randomly according to preassigned probabilities), then every n-player game in which every player can chose from finitely many strategies admits at least one Nash equilibrium of mixed strategies.

Example: Prisoner's dilemma

The Prisoner's dilemma has one Nash equilibrium: when both players defect. However, "both defect" is clearly inferior to "both cooperate". The strategy "both cooperate" is unstable, as a player could do better by defecting while their opponent still cooperates. This indicates one of the limitations of using the Nash equilibrium to analyze a game. As Ian Stewart put it, ‘sometimes rational decisions aren't sensible!’
