Market structure can be determined by measuring the degree of suppliers' market concentration, which in turn reveals the nature of market competition. The degree of market power refers to firms' ability to affect the price of a good and thus, raise the market price of the good or service above marginal cost (MC).
In welfare economics, the theory of the second best concerns the situation when one or more optimality conditions cannot be satisfied. [1] The economists Richard Lipsey and Kelvin Lancaster showed in 1956 that if one optimality condition in an economic model cannot be satisfied, it is possible that the next-best solution involves changing other variables away from the values that would ...
In effect, they internalise the market in knowledge within the firm. The theory claims the internalization leads to larger, more multinational enterprises, because knowledge is a public good .

Even though the contract is signed as a secured loan , because of the enforcement costs, the lender never gets the full payment in case of default.

While several contingent claims are traded routinely against many states such as insurance policies, futures, financial options, among others, the set of outcomes is far greater than the set of claims.
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).
