Read Eye on U.S. Potential GDP. Explain why U.S. potential GDP per worker per week is greater than that in Europe. What could induce Europeans to work the same hours as Americans and would that close the gap between potential GDP per worker in the two economies?

OA. raising; raising OB. lowering; raising C. raising; lowering D. lowering; lowering Everything else remaining the same, if Europeans work the same hours as Americans, the gap between potential GDP per workers in the two economies OA. is eliminated because potential GDP is determined by labor hours B. becomes smaller but is not eliminated because U.S. workers are more productive per hour of work C. becomes smaller but is not eliminated because of an increase in European wages D. remains unchanged because of similar stocks of capital
