Question Completion Status QUESTIONS Consider two countries, labeled 1 and 2. Each has the production function Y-A;K13L13,-1,2. If the only difference between the two countries is that Aj > A2, Country 2 will not produce anything, ceteris paribus (.e. without changing anything else). Country 2 will produce more than Country 1, ceteris paribus. Country I will produce more than Country 2, ceteris paribus. Each will produce the same amount, ceteris paribus.
