假设利率平价并不完全成立,而真实的关系是R=R*+(Ee-E)/E+ρ,其中,ρ衡量的是国内储蓄与国外储蓄之间的风险差
假设利率平价并不完全成立,而真实的关系是R=R*+(Ee-E)/E+ρ,其中,ρ衡量的是国内储蓄与国外储蓄之间的风险差异。假设政府开支出现永久性的增加。由于可能导致的政府赤字,ρ也增大了,即本币存款的风险变大。请分析一下在此情况下这一政策对产出的影响。
Suppose that interest parity does not hold exactly,but that the true relationship is R=R*+(Ee-E)/E+ρ where ρ is a term measuring the differential riskiness of domestic versus foreign deposits.Suppose a permanent rise in domestic government spending,by creating the prospect of future government deficits,also raises ρ,that is,makes domestic currency deposits more risky.Evaluate the policy's output effects in this situation.
