中文摘要 | 本文以無窮生命的代表性個人為基礎介紹幾個內生成長模型。如果經濟體系中以每人衡量的生產技術其固定規模報酬或報酬遞增,或是生產技街依賴於人力資本的累積,即使沒有外生的技術進步,經濟有時仍會持續成長,而有別於傳統的Solow模型。本文首先介紹的是Rebelo (1991) 的固定規模報酬模型以及Lucas (1988) 有關人力資本累積的模型,並連帶考慮生產技術的外溢致果,以及 Romer (1986) 的報酬遞增模型。接著利用已建立的模型討論政府賦稅典公共支出對經濟成長的影響,主要的參考為Barro (1990) 與Lin (1994)。最後將內生成長延伸至貨幣經濟,而分別以貨幣進入效用函數 (MIU)、預持現金 (CIA) 限制以及存在交易成本的架構將貨幣導入模型。若內生成長率不受貨幣 (成長率) 的影響則表示 (超) 中立性存在;本文在MIU的架構中得到這種結果,然而交易成本的摩擦、預持現金的限制在購買消費財與投資財的不同設定將會影響貨幣 (超) 中立性的存在,一如Stockman (1981) 的結果。 |
英文摘要 | This paper introduces several endogenous growth models based on representative agent with infinite horizon. If per capita production technology has the property of constant returns to scale or increasing returns, or there is accumulation of human capital, then there might be endogenous growth of economy even without technological progress. This is an obvious difference from the traditional Solow's exogenous growth model. At the outset, Rebelo (1991)'s AK model and Lucas(1988)' model of human capital accumulation are introduced, by the way consider the spillover effect of technological externalities. Romer (1986)'s model of increasing returns are also discussed. Next, effects of taxation and public expenditure on growth are presented based on Barro (1990) and Lin (1994). Finally, we introduce money into the economy by letting money in the utility function (MIU), imposing cash in advance (CIA) constraints and specifying transaction cost on purchasing goods to derive endogenous growth in these kinds of economies. If growth rate of economy is independent of (growth rate of) money, then (super) neutrality holds. We find (super) neutrality in MIU economy but different specifications of CIA constraints or transaction costs on consumption and investment goods will influence the presence of (super) neutrality which is consistent with Stockman(1981)'s results. |
