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.
The public goods game is a standard of experimental economics. In the basic game, subjects secretly choose how many of their private tokens to put into a public pot. The tokens in this pot are multiplied by a factor (greater than one and less than the number of players, N) and this "public good" payoff is evenly divided among players. Each ...
Sonnenschein-Mantel-Debreu theorem (SMD theorem) is a theorem for exchange economy that can be expressed in the following way: . for a function that is continuous, homogeneous of degree zero, and in accord with Walras's law,there is an economy with at least as many agents as goods such that, for prices bounded away from zero, the function is the aggregate demand function for this economy.
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'.

Equity premium puzzle: The equity premium puzzle is thought to be one of the most important outstanding questions in neoclassical economics. [6] It is founded on the basis that over the last one hundred years or so the average real return to stocks in the US has been substantially higher than that of bonds.
The price vector depends on the initial allocation. E.g., if the initial allocation is equal, [(3,3);(3,3)], then both agents have the same budget in CE, so = =. This CE is essentially unique: the price vector may be multiplied by a constant factor, but the CE equilibrium will not change. B.
The variables are collected in a vector, y t, which is of length k. (Equivalently, this vector might be described as a (k × 1)-matrix.) The vector is modelled as a linear function of its previous value. The vector's components are referred to as y i,t, meaning the observation at time t of the i th variable.
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).
