Identify three macroeconomic variables in the United States that impact the supply and/or demand of the product or service produced by the company Apple. Interpret the trends of the three selected macroeconomic variables for the past three years and evaluate how these trends will likely impact the supply and demand of Apple's product or service as well as their financial performance.

Apple's performance is closely tied to macroeconomic conditions. GDP, inflation, and unemployment are the three most important macroeconomic variables, and they will impact Apple's performance significantly. The demand for Apple's products and services is likely to increase steadily. In response, Apple is likely to increase its supply accordingly.

The United States has enjoyed a steady rate of growth over the past three years. GDP growth has been near 3 percent, which is quite high for an advanced economy such as the United States. Inflation, as measured by changes in the consumer price index (CPI), has been mild over the past three years, hovering around 2 percent. The unemployment rate has been falling over the last three years, reaching below four percent in recent months which is very low indeed. The U.S. economy is currently operating near full employment.

Taken together, a steady rate of growth, low inflation, and low unemployment indicate that demand for Apple's products is going to be strong in the near term. Apple is likely to be able to match this rising demand with an increase in supply.
