The model was first presented by Oliver Williamson in his 1968 paper "Economies as an Antitrust Defense: The welfare tradeoffs" in the American Economic Review. [2] Williamson argued that ignoring efficiencies that may result from proposed mergers in antitrust law "fail[ed] to meet the basic test of economic rationality". [3]
In law, a monopoly is a business entity that has significant market power, that is, the power to charge overly high prices, which is associated with unfair price raises. [2] Although monopolies may be big businesses, size is not a characteristic of a monopoly. A small business may still have the power to raise prices in a small industry (or ...
Welfare economics is a field of economics that applies microeconomic techniques to evaluate the overall well-being (welfare) of a society. [ 1 ] The principles of welfare economics are often used to inform public economics , which focuses on the ways in which government intervention can improve social welfare .
Note that the above mechanisms only solve the problem of double marginalization; from an overall welfare point of view, the problem of monopoly pricing remains. It should also be noted that while some of the solutions presented above, such as mergers, have a positive effect in minimizing the double markup present within the vertical competition ...
Pricing, quantity, and welfare effects of a binding price ceiling. There is a substantial body of research showing that under some circumstances price ceilings can, paradoxically, lead to higher prices. The leading explanation is that price ceilings serve to coordinate collusion among suppliers who would otherwise compete on price.
The Ramsey problem, or Ramsey pricing, or Ramsey–Boiteux pricing, is a second-best policy problem concerning what prices a public monopoly should charge for the various products it sells in order to maximize social welfare (the sum of producer and consumer surplus) while earning enough revenue to cover its fixed costs.
In mainstream economics, economic surplus, also known as total welfare or total social welfare or Marshallian surplus (after Alfred Marshall), is either of two related quantities: Consumer surplus , or consumers' surplus , is the monetary gain obtained by consumers because they are able to purchase a product for a price that is less than the ...
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).
