Conditions on G (the stage game) – whether there are any technical conditions that should hold in the one-shot game in order for the theorem to work. Conditions on x (the target payoff vector of the repeated game) – whether the theorem works for any individually rational and feasible payoff vector, or only on a subset of these vectors.
Transformation problem: The transformation problem is the problem specific to Marxist economics, and not to economics in general, of finding a general rule by which to transform the values of commodities based on socially necessary labour time into the competitive prices of the marketplace. The essential difficulty is how to reconcile profit in ...
A competitive equilibrium is a price vector and an allocation in which the demands of all agents are satisfied (the demand of each good equals its supply). In a linear economy, it consists of a price vector and an allocation , giving each agent a bundle such that:
If y is a production vector and p is the economy's price vector, then p·y is the value of net output. The mill's owner will normally choose y from the production set to maximise this quantity. p·y is defined as the 'profit' of the vector y, and the mill-owner's behaviour is described as 'profit-maximising'.

[1] The aggregation problem is the difficult problem of finding a valid way to treat an empirical or theoretical aggregate as if it reacted like a less-aggregated measure, say, about behavior of an individual agent as described in general microeconomic theory [1] (see representative agent and heterogeneity in economics).
Chapter 1, "The Lesson", explains that economics is a field filled with fallacies because of the difficulties inherent in the subject and the special pleading of selfish interests. [3] Every group has economic interests antagonistic to other groups.
There are two fundamental theorems of welfare economics.The first states that in economic equilibrium, a set of complete markets, with complete information, and in perfect competition, will be Pareto optimal (in the sense that no further exchange would make one person better off without making another worse off).
This requires that the amount of saved output be exactly what is needed to (1) equip any additional workers and (2) replace any worn out capital. In a steady state, therefore: s f ( k ) = ( n + d ) k {\displaystyle sf(k)=(n+d)k} , where n is the constant exogenous population growth rate, and d is the constant exogenous rate of depreciation of ...
