It can be referenced to the article: Berry, Steven, James Levinsohn and Ariel Pakes, 1995, "Automobile Prices in Market Equilibrium," Econometrica, 63(4), 841-890 Record Layout: Each record of AUTO.ASC contains the following variables, with the variables names in the first record: columns 1-6 - name Model name (abbreviation) columns 9-12 - id Identification number for model columns 15-16 - yr Year column 19 - cy Number of cylinders column 22 - dr 2=Two wheel drive, 4=Four wheel drive column 25 - at 1=Automatic transmission, 0=otherwise column 28 - ps 1=Power steering, 0=otherwise column 31 - air 1=Air conditioning, 0=otherwise columns 34 - drv 1=Front wheel drive, 0=otherwise (the 1971-1974 data is missing) columns 37-41 - price Price (dollars) columns 44-47 - wght Weight (pounds) column 50 - dom 1=U.S. built, 0=imported columns 53-57 - disp Displacement (cubic inches; liters in 1990) columns 60-63 - hp Horsepower columns 65-69 - lngth Length (inches) columns 72-75 - wdth Width (inches) columns 78-82 - wb Wheel base (inches) columns 85-89 - mpg Miles per gallon columns 92-97 - sales Sales columns 100-101 - fid Firm identification number column 104 - eu 1=European model, 0=otherwise column 107 - re Reliability index (from Consumer Reports) column 110 - dfi 1=Transplant production in the U.S. 0=otherwise columns 113-118 - markup Estimated markup (thousands of dollars) Special Considerations: The displacement variable switched from cubic inches to liters in 1990. To convert these back to cubic inches, the displacement can be multiplied by 61.02.
