Pfizer Macroeconomics - Term Paper Example Unemployment is also another macroeconomic variable that affect the company’s’ supply and demand.

When there is cost-push inflation, the company is forced to pass the cost to the consumers leading to increased prices. The result from the cost-pull inflation is that there is low demand for our products and usually our competitors take advantage of the situation. Also, interest rate is another variable that affect the demand and supply of our medicines.
