1. 美國對貿易夥伴課徵「對等關稅」，試問提高關稅對美國商品市場有何影響？請繪圖並輔以文字詳細說明此政策對進口商品數量、消費者剩餘、生產者剩餘和絕對損失(deadweight loss)的影響。(25%)
2. 若因關稅增加，生產者對進口商品提高售價，請利用消費者選擇理論繪圖並輔以文字詳細說明進口商品價格上漲可能產生的替代效果、所得效果和價格效果。(15%)
3. 承2題，若因關稅增加導致通貨膨脹，政府擬調高基本薪資以降低通貨膨脹對經濟的衝擊。請利用消費者選擇理論繪圖並輔以文字詳細說明所得增加對進口商品可能產生的價格效果，並繪製推導出恩格爾曲線。(10%)
二、簡答題

1. Consider a Ramsey model in which the social planner weighs future consumption according to the number of people who will be alive in the following manner: $$V=\int{0}^{\infty}e^{-dt}U(c{t})N(t)^{\frac{1}{2}}dt$$, where $$0<\pi<1$$. Population grows exogenously at rate $$n>0$$, $$\dot{N}=nN$$. At time zero, population is $$N_{0}$$. The rest of the problem is standard. There is no technological progress. The deprecation rate is zero. The production function is $$y=k^{n}$$, and the differential equation for capital stock is $$\dot{k}=f(k)-c-nk$$.

(1) What assumption regarding the values of \( n \), \( \pi \), and \( \theta \) is required to ensure that the social planner's utility is finite? (10%)
(2) Making this assumption, solve for the steady state level of capital per worker. (20%)
2. (1) Draw the IS-LM-BP diagram and discuss the effect of expansionary fiscal policy with fixed rate under relative capital mobility (BP curve is flatter than LM curve). (10%)
(2) Draw the IS-LM-BP diagram and discuss the effect of expansionary monetary policy with flexible exchange rate under relative capital immobility (BP curve is steeper than LM curve). (10%)
