Solution to Quiz 1

 

If originally two units of labor were required to produce each unit of each good, then the opportunity cost of each unit of food was one unit of shelter and vice versa.  Consequently, the production possibilities curve was a straight line. After the innovation, one unit of labor was required to produce each unit of food.  The transfer of unit of labor from the production of shelter would reduce the production of shelter by .5 units.  Consequently, the opportunity cost of each unit of food after the innovation was .5 units of shelter.  Similarly, after the innovation the opportunity cost of each unit of shelter was two units of food.  Therefore, the production possibilities curve was also a straight line after the innovation.  If all 200 units of labor were devoted to food production, then the country could produce a maximum of 100 units of food before the innovation and 200 units of food after the innovation, causing the maximum number of units of food it could produce to double.
