Question

As the cost accounting manager at Cambria Chemicals (CC), you are responsible for compiling and reporting various performance measures to the senior managers. The company instituted many efficiency improvement programs recently, and the CFO has asked you to measure and report total factor productivity measures based on the three inputs (material, labor, and overhead). Data for the last two years follow:

	Year 2			Year 1
Gallons input (thousands)		10,600			9,600
Labor-hours (thousands)		8,900			6,500
Gallons of output (thousands)		12,400			10,400

From the accounting records, you also gather the following information for the two years:

	Year 2				Year 1
Cost of inputs (per gallon)	$	79			$	79
Wage rate (per hour)	$	25			$	16
Total manufacturing overhead	$	1,360,000			$	1,210,000
Selling price of output (per gallon)	$	380			$	385

Required:

a. Compute the total factor productivity measures for year 1 and year 2 based on the three inputs (material, labor, and overhead).

	Year 2 Year 1 Total factor productivity
