When the sources of economic growth are stated as a production function,which factor is treated as a multiplier?

Answer:A
Economic output can be stated as a production function of the form Y=A׃(L,K),where Y is economic output,L is the size of the labor force,K is the amount of capital available,and A is total factor productivity.
解析：
这个重点首先是要记住公式，Y=A׃(L,K)
其中，A是全要素生产率，L是劳动力，K是可用资本
那题目问的是可作为multiplier的是？那就是A，全要素生产率，选A。
