One thing that distinguishes the short run and the long run is
the existence of at least one fixed input.
Explanation:
On the long run, all productive inputs can be changed and/or altered. that includes fixed costs like equipment and machinery, building facilities, processes, wages, etc.
On the short run, at least one of the inputs used to produce our goods or services cannot be changed, e.g. wages tend to be sticky, fixed costs (depreciation of equipment and machinery, buildings, etc.)
The monetarist theory is a theory which believes that the changes in the supply of money is the most important factor in the growth of an economy.
In this concept, economic stability can be fostered through targeting the money supply. The theory assume that the fluctuations in both the investment and consumption expenditure, which are s a result of the fluctuations in growth rate of the quantity of money, are the main source of fluctuations in aggregate demand.
<span>A fast-food restaurant decides to raise the price of its hamburgers. assume the firm is in a monopolistically competitive industry. what will happen to the demand for its hamburgers? When the fast-food restaurant raises the price of hamburgers, some customers may stay and pay the higher price because they want that specific brand of hamburgers, other may go elsewhere to find them cheaper.
When prices raise, some customers stay because they are attached to that specific company, others leave because they want a burger but for a lower price. </span>
