Macroeconomic Measures of Output, Prices and their Justification in Planning  
Big Drive Auto tracks vehicle unit sales and its own price index of vehicle sales prices with 2000 as the base year.   Using Real Gross Domestic Product (GDP) and Consumer Price Index (CPI), an aggregate demand and supply curve can be generated to determine vehicle pricing levels as well as supply levels of inventory.   The Real GDP takes into account consumption, gross investments, government spending, exports, and imports.   Specifically, the GDP subcategory of motor vehicle durable goods can be tracked and used for planning of staffing and prices.
