Costs, Revenues, Profits and the Growth of Firms

What Costs, Revenues, Profits and the Growth of Firms covers

Costs, Revenues, Profits and the Growth of Firms is examined in Microeconomics — assessed across all three components. It covers prices, profit and the allocation of resources, the short run, the long run and diminishing returns, total, average and marginal product, fixed and variable costs in the short run, average and marginal cost curves and their shapes, total, average and marginal revenue, economies and diseconomies of scale and the long run average cost curve, profit maximisation and the MC = MR rule, normal profit, abnormal profit and economic profit, internal and external growth and types of integration and productive, allocative, dynamic and Pareto efficiency.

Questions from this topic

Each one with the model answer underneath.

1. 1

   What is meant by the allocation of resources?

   Model answer

   The allocation of resources is the way scarce factors of production are divided between competing uses. Resources are allocated in a free market by the price mechanism rather than by government direction.

2. 2

   State the three functions of prices in a free market.

   Model answer

   Prices signal where goods are scarce, ration demand when supply is short, and reward firms that produce. The three functions together move resources towards their most valued uses.

3. 3

   How does the signalling function of prices work?

   Model answer

   A rising price signals to producers that consumers want more of a good. Resources move into that industry in response to the signal.

4. 4

   How does the rationing function of prices work?

   Model answer

   A higher price rations a scarce good among the buyers who value it most. Consumers who are unwilling to pay the price drop out of the market.

5. 5

   How does the incentive function of prices work?

   Model answer

   A higher price raises the profit available from producing a good. Firms have an incentive to expand output and new firms enter the industry.

6. 6

   What role does profit play in allocating resources?

   Model answer

   Profit shows where consumers value output more than the resources used to make it. Resources flow towards industries earning high profit and away from loss-making ones.
