同学,你好:
先看等式:Excess stock market returnt= a0+ a1Default spreadt–1+ a2Term spreadt–1+ a3Pres party dummyt–1+ et
其中,Pres party dummy is equal to 1 if the US President is a member of the Democratic Party and 0 if a member of the Republican Party. (all data are in percent form)
再者,Please refer to Pres party dummyt-1的系数 = 3.17 and this can answer your question. Dummy variable哑变量为0或为1时,相差的就是3.17。
