Identify three macroeconomic variables in the United States that impact the supply and/or demand of the product BAI by Wal-Mart which I selected for my microeconomic/macroeconomic analysis papers.

Interpret the trends of the three selected macroeconomic variables for the past three years.

Evaluate how these trends will likely impact the supply and demand of the BAI product as well as the financial performance of Wal-Mart.
