Suppose it takes a total of 100 hours to produce a car (mathematically speaking, this means one hour of work “produces 0.01 cars”). If the average wage in car making is $50 per hour, and each car needs $1,000 worth of inputs other than labor, C1: What is the unit labor cost of cars? C2: If both labor productivity and wages double, what happens to unit labor costs? C3: If cars are selling for $10,000, how much profit is generated per car? C4: If the producer can double production speeds by increasing wages to $80 per hour, how much profit will it make per car at this price for cars?
