What is the level of productivity in this economy? b. What is the per-unit cost of production if the price of each input unit is $2? $ C. Assume that the input price increases from $2 to $3 with no accompanying change in productivity. What is the new per-unit cost of production? In what direction would the $1 increase in input price push the economy's aggregate supply curve?
