假设利率平价并不完全成立，而真实的关系是R=R^*+(E^e-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^*+(E^e-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．
