How market structures determine the pricing and output decisions of businesses?
There are different kinds of markets in different economies/sectors/goods. Accordingly, there are different kinds of output and pricing decisions which take place. Usually, output and pricing decisions are interdependent except for the case of perfectly competitive markets. In perfectly competitive markets, a single firm is so small compared to the market that it cannot affect the prices. In that case, it must take the price as given, and then decide the quantity to be supplied. Price in this market is equal to the marginal cost of production. In monopoly, however, things are different. The monopolist can change the prices, as it is the sole provider of the good and thus has the market power. But here also, if the price increases quantity demanded decreases. Therefore, the monopolist must take under consideration both the positive and negative effects of increase in prices. In another market oligopoly, pricing is a bit more complicated and it depends upon the strategic interaction among the firms.
