Answer: A - nominal wages are slow to adjust to changing economic conditions
Explanation:
In the short run, the costs of many of the factors used in the production process are fixed. For example labours wage is fixed for a number of years because of labour contracts. Also the raw materials used in the production process have long term agreements that fix their prices.
As a result of factors of production been fixed in the short run, when general price level rises and the cost of production remains constant, profit also rises.
Firms take advantage of this rise in price and increase production and the quantity of aggregate supply increases. This is why the short run aggregate supply curve is upward sloping.
In the long run, perfectly competitive firms will react to profits by increasing production.
Firms in a perfectly competitive world earn zero profit in the long run. While firms can earn accounting profits in the long run, they cannot earn economic profits.
In the long run, perfectly competitive firms will react to profits by decreasing production. CORRECT: In the long run, perfectly competitive firms will respond to losses by exiting the market. In the long run, perfectly competitive firms will respond to losses by reducing production.
A perfectly competitive market achieves long‐run equilibrium when all firms are earning zero economic profits and when the number of firms in the market is not changing.
In the long run, profits and losses are eliminated because an infinite number of firms are producing infinitely divisible, homogeneous products. Firms experience no barriers to entry and all consumers have perfect information.
