Consider Miller Chemicals that produces water purification crystals for swimming pools. The major inputs used in the production process are labor, raw materials and energy. The labor costs are $$200,000$; raw materials costs are $$80,000$; and energy costs are $$9,000.$

Labor costs in year two are $$350,000$; raw materials costs $$95,000$; and energy costs $$11,000.$

Labor costs in year three are $$350,000$; raw materials costs $$40,000$; and energy costs $$6,000.$

Miller Chemical produced $100,000$ pounds of crystal in year $1$; $150,000$ pounds of crystals in year $2,$ and $184,500$ pounds of crystals in year $3.$

The productivity in year two increases$/$decreases by Blank $1$ and the productivity from year one to year three increases$/$decreases by Blank $2.($Enter your numbers only. R
