家庭如何安排開銷、企業如何決定是否投資,都可能影響整體景氣。2026年諾貝爾經濟學獎得主霍爾與伍德福的研究,正是將家庭與企業的決策納入經濟模型,分析這些選擇如何牽動經濟變化;情境照。

每個月要繳房貸,去市場買菜覺得愈來愈貴,薪水卻沒有增加多少。這些生活上的變化,和整體景氣有什麼關係?2026年諾貝爾經濟學獎頒給美國經濟學家霍爾與伍德福,表彰兩人研究家庭和企業的決定如何影響整體經濟,以及政府與央行的政策會帶來什麼影響。

假設房貸利率調高,部分借款人每個月就得多繳一些錢。原本打算買家電、帶家人出去吃飯的預算,可能得先省下來。如果不少家庭都減少花費,商家的生意也可能受到影響,企業接著可能放慢投資或徵才。

利率降低時,情況也可能反過來,但不代表大家一定會多花錢。有人擔心工作不穩,寧可把錢存起來;有些企業即使借錢比較便宜,也可能因為訂單不夠而不敢擴大經營。影響景氣的因素很多,利率只是其中之一。

家庭與企業的決定如何牽動景氣

霍爾與伍德福的研究,把家庭和企業如何做決定納入經濟模型。分析整體經濟時,經濟學家會觀察通膨、消費和生產等數字;兩人的研究則從家庭與企業的行為出發,分析這些決定如何影響整體經濟。

例如,民眾擔心收入不穩,可能減少非必要開銷;企業發現生意變差,也可能暫緩招募或投資。這些情況如果同時發生,就可能影響消費、就業和經濟活動。經濟模型能幫助研究人員分析其中的關係,也供政策制定者評估不同措施可能帶來的影響。

央行決定升息或降息,也得考慮物價和景氣。升息可能抑制需求、減輕通膨壓力,但部分借款人的負擔也可能增加;降息能降低借貸成本,卻不代表企業一定會增加投資,民眾也不一定會因此多消費。

瑞典皇家科學院指出,霍爾與伍德福的研究改變了經濟學分析穩定政策的方式。他們相關的新凱因斯模型,可用來解釋及量化穩定政策對景氣循環的影響,目前已為世界各地中央銀行與財政部門採用。
