  Intertemporal Planning, Exchange and Macroeconomics - Cambridge University Press
This book is an original and rigorous effort to incorporate into modern general equilibrium macroeconomics an analysis of the transactions and accumulation behavior of individuals.
It has become widely recognized that much of the demise of contemporary macroeconomic analysis is attributable to the absence of a foundation in microeconomic and general equilibrium theory.
The role of a government in aiding the economy to attain an efficient equilibrium is discussed.

 Capital and Equilibrium
An important aspect of this approach is its move away from the purely physical dimensions of equilibrium as a state of rest or balance of forces, to one firmly based in the human mind.
Equilibrium is here conceived as a situation in which individual knowledge and expectations, and the actions based on these, are compatible with the 'data,' where the 'data' for one individual include the actions of other individuals.
While it is true that equilibrium "is in the model and not in the world,"[3] we shall want to build a bridge between the 'model' and the 'world' and maintain that timeless models cannot do this.

 Dale Jorgenson's Collected Works
It is important to recognize at the outset that the dominant tradition in general equilibrium modeling does not employ econometric methods.
Both these mechanisms are captured by the intertemporal general equilibrium that Wilcoxen and I have presented in Chapter 3.
Intertemporal general equilibrium modeling provides a very worthwhile addition to methodologies for evaluating the impact of energy, environmental, trade, and tax policies.

 Arrow-Debreu Model of Intertemporal Equilibrium
An "equilibrium of a private ownership economy" is a vector of prices, a consumption plan chosen by each consumer, and a production plan chosen by each producer where the consumers have maximized utility, the firms have maximized profits, and the demand for every commodity does not exceed the total endowments.
The relationship of an equilibrium to the given data can be quite complicated, sometimes counter-intuitive: "Even people who have made no study of economic theory are familiar with the idea that when something is more plentiful its price will be lower, and introductory courses on economic theory reinforce this common presumption with various examples.
Thus, the equilibrium, if any, that would be reached by a dynamic adjustment process taking time would not correspond to the original data of the Arrow-Debreu equilibrium.

 BUSINESS CYCLE THEORY
The market process that eventually reveals the intertemporal misallocation and turns boom into bust resembles an analogous process described by the British Currency School, in which international misallocations induced by credit expansion are subsequently eliminated by changes in the terms of trade and hence in specie flow.
Each figure represents a state of equilibrium in the loan market: the market-clearing rate of interest is i, as shown on the vertical axis; the amount of income saved and borrowed for investment purposes is A, as shown on the horizontal axis.
Mainstream macroeconomists take structural problems (intertemporal or otherwise) to be completely separate from the general problem of demand deficiency and the periodic problem of downward spirals of demand and income.

 What is Truth in Capital Theory? -- Theme 3: Capital, Time and the Interest Rate
In order to show why equilibrium would not be achieved in the contingent world, the nature of the errors that could be made and their consequences, and why the differences between entrepreneurial and bureaucratic responses were important, Hayek (like Knight) adopted a notion of theorizing that departed from the common method of successive approximation.
Nevertheless, Hayek's development of a pure logic of intertemporal equilibrium (systematically articulated in Hayek (1941), but identified in Hayek 1936) was still unacceptable to Knight, although it is difficult to provide a clear and consistent account of the reasons for their disagreement.
Hayek moves to an intertemporal micro-economic theory, while Knight continues to treat society's output in the aggregate, although it would be better to say that he considers society's output to be a non-divisible whole, like the choral performance.

 Financial Markets, Intermediaries and Intertemporal Smoothing - Knowledge@Wharton
They demonstrate that in market equilibrium the safe asset is not usually held but, in fact, is dominated by the risky asset.
They demonstrate that by accumulating reserves in the form of the safe asset and using them to "smooth" the returns to the risky asset, it is possible to increase the welfare of all but a negligible set of agents by a non-negligible and uniform amount.
The authors then interpret intertemporal smoothing as the product of intermediation and suggest that the contrasting performance of the U.S. and German economies may be understood in terms of this intertemporal smoothing mechanism.

 FROM LACHMANN TO LUCAS
With noteworthy exceptions, the attention to the intertemporal aspect of the coordination problem in modern macroeconomics is on the wane.
This variant of Keynesianism, however, is concerned not with the prospects for achieving an intertemporal equilibrium but rather with the prospects for clearing the labor market in each period--whether or not investment spending in a given period corresponds to consumer spending in some future period.
The claim that there is a general tendency toward equilibrium rests on the understanding of a market process in which each investor is investing on the basis of his own expectations.

 SSRN-Intertemporal Price Discrimination with Forward-Looking Consumers: Application to the US Market for Console ...
Firms in durable good product markets face incentives to intertemporally price discriminate, by setting high initial prices to sell to consumers with the highest willingness to pay, and cutting prices thereafter to appeal to those with lower willingness to pay.
Prices in our model are equilibrium outcomes of a game played between forward-looking consumers who strategically delay purchases to avail of lower prices in the future, and a forward-looking firm that takes this consumer behavior into account in formulating its optimal pricing policy.
Simulations reveal that the profit losses of ignoring forward-looking behavior by consumers are large and economically significant, and suggest that market research that provides information regarding the extent of discounting by consumers is valuable to video-game firms.

With the aid of an intertemporal, multi-region general equilibrium model, we study issues of agricultural trade liberalization, growth and capital accumulation in the context of a world economy moving towards a multi-polar structure.
The model is based on intertemporal general equilibrium theory with Ramsey-type dynamics.
A key feature of the model is its explicit recognition of both the commodity and foreign capital flows across regions in an endogenous setting, and its explicit portrayal of the out-of-steady state dynamics under an intertemporal optimization framework.

 Lachmann, Capital and Its Structure, Chapter 5: Library of Economics and Liberty
We shall then attempt to show that the validity of the argument is not impaired by recent 'monetary' doctrines of the interest rate as long as the difference between equilibrium conditions and the equilibrating mechanism is firmly kept in mind.
We shall see that once we distinguish clearly between equilibrium and disequilibrium conditions, and take the trouble to define the circumstances in which intertemporal equilibrium is at all conceivable, the substance of the controversy vanishes.
The case is exactly parallel to the over-all equilibrium in the forward exchange market which subsists despite differences in interest rates in different financial centres which will make the 'swap' rates vary, but do not affect the net rate of profit.

The Vienna question, the existence of equilibrium, was proved by Arrow and Debreu (1954), Lionel McKenzie (1954), David Gale (1955) and Hukukane Nikaido (1956), using fixed-point theorems created around this time.
Local and global stability of equilibrium was pursued in the late 1950s and early 1960s, notably by Kenneth Arrow and Leonid Hurwicz (1958, 1959) and Lionel McKenzie (1960).
The incorporation of capital theory, in the form of an intertemporal equilibrium, was effectively accomplished by Edmond Malinvaud (1953).

 The G-Cubed Model   (Site not responding. Last check: 2007-11-05)
Intertemporal budget constraints are imposed on households, governments and nations (the latter through accumulations of foreign debt).
Overall, the model is designed to provide a bridge between computable general equilibrium models and macroeconomic models by integrating the more desirable features of both approaches.
Consumers in the model also decide on intertemporal consumption and the composition of the consumption basket at each point in time based on perceptions of wealth based on existing information and current income.

 The Austrian Theory of the Trade Cycle, The Austrian Theory: A Summary
Market mechanisms that allocate resources within the capital structure are imperfect enough to permit substantial intertemporal disequilibria, but the market process that shifts output from the near to the more remote future when savings preferences have not changed is bound to be ill-fated.
The self-aggravating contraction of economic activity was designated as a "secondary depression" by the Austrians to distinguish it from the structural maladjustment that, in their view, is the primary problem.
Questions of policy and institutional reform are answered differently by Austrian and mainstream economists because of the difference in focus as between intertemporal misallocations and downward spirals.

"since both groups of versions of marginalist equilibrium theory - the long-period versions and the neo-Walrasian versions - encounter what appear to be radical and insurmountable difficulties, one must conclude that at present there is no defensible neoclassical theory (in the sense of explanation) of prices and distribution.

 RePEc
The main reason for this result to be true is that in contrary to the Arrow-Debreu model where final consumption allocations for all periods are reached immediately in the first period, in an Intertemporal General Equilibrium Model they are reached via futures and spot markets transactions.
The consequence of this two stage allocation process is that the incomes in every period are determined by the evaluation of endowments which are the result of the equilibrium process in futures markets of the period before and thus far away from being arbitrary as in the Arrow-Debreu Model.
But with incomplete financial markets, heterogeneous expectations lying in an appropriate set of dimension S-L (where S is the number of states of the world and L the number of assets) still lead to a monotone spot market excess demand function.

 An Intertemporal Model of Segmentation - Knowledge@Wharton
Within the model, under various forms of segmentation/integration, the equilibrium asset prices and allocations, the risk-free interest rate, and the intertemporal consumption behavior and welfares of two countries are derived and compared.
It is shown that the equilibrium interest rate is increased on integration, and that integrating markets may be significantly welfare decreasing for one of the countries.
The conclusions as to the effects of segmentation on asset prices in the mean variance model of the existing finance segmentation literature are also shown to break down in an intertemporal model.
