Optimal stopping problems can be found in areas of statistics, economics, and mathematical finance (related to the pricing of American options). A key example of an optimal stopping problem is the secretary problem.
Example: Agricultural products which have many buyers and sellers, selling homogeneous goods where the price is determined by the demand and supply of the market and not individual firms. In the short run, a firm in a perfectly competitive market may gain profits or loss, but in the long run, due to the entry and exit of new firms, price will ...
Conventionally stated, the shutdown rule is: "in the short run a firm should continue to operate if price equals or exceeds average variable costs." [4] Restated, the rule is that to produce in the short run a firm must earn sufficient revenue to cover its variable costs. [5] The rationale for the rule is straightforward.
Graphs of probabilities of getting the best candidate (red circles) from n applications, and k/n (blue crosses) where k is the sample size. The secretary problem demonstrates a scenario involving optimal stopping theory [1] [2] that is studied extensively in the fields of applied probability, statistics, and decision theory.
Law of Demand is relied heavily upon by managerial economics, which is a branch of economics that applies microeconomic analysis to managerial decision-making, to make informed decisions on pricing, production, and marketing strategies.
In other words, the rule is that the size of the markup of price over the marginal cost is inversely related to the absolute value of the price elasticity of demand for the good. [10] The optimal markup rule also implies that a non-competitive firm will produce on the elastic region of its market demand curve. Marginal cost is positive.
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 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 ...
