1 對消費者補貼通常會造成什麼現象?A: (B)補貼會造成需求線右移 並造成無謂損失(DWL)畫圖才能更明確的解釋很抱歉只能跟你解答到這2.下列何者不是價格上限會造成的經濟浪費現象?A:(D)解析:(A): 價格上限通常會訂定一個低於供需模型所決定的均衡價格 所以消費者會因為便宜而造成排隊的現象(B): 因為必須要排隊購買 所以必定會造成有人向隅的情況 也就是說 限量是殘酷 (C): 因為價格太低 所以廠商會不想生產(D): 如果你認為你的邊際效益 會比花錢買這樣東西的邊際成本來的低 那還不如把錢留著(貨幣的邊際效益) 白話一點就是 你手中握有100元的效用是10

但是你買一本雜誌所 得到的效用只有9 那你為何不把100元留著呢? 那不是比較爽嗎!這是我個人的拙見如果有錯還請網友們指教 參考資料 自己
