政府公債佔GDP的最適比率 / The optimal ratio of public debt to GDP林銘峰, Lin, Ming Feng Unknown Date (has links)
本文研究目的是在動態隨機一般均衡模型當中,討論政府公債佔國內生產毛額的最適比率。本文建立一封閉經濟體系,討論政府公債佔國內生產毛額的比率改變時,對主要的經濟變數有何影響。不同於先前的研究,我們假設在極大化福利的前提下,找尋最適的政府公債佔國內生產毛額比率。靜止均衡的分析發現,政府公債佔國內生產毛額的比率與消費呈現正向變動的關係,與產出和勞動有著負向變動的關係。除此之外,當政府公債佔國內生產毛額的比率增加時,福利水準會越來越低,因此,最適的公債比率為零。 / The objective of this paper is to investigate the optimal ratio of public debt to GDP by using a micro-based dynamic stochastic general equilibrium (DSGE) model. In this paper, the model that we build is a closed economy. We discuss the effect of the optimal public debt to GDP ratio on primary variables. Different from previous research, we look for the optimal ratio of public debt to GDP that will maximize welfare. In the steady state analysis, we find that the ratio of public debt to GDP has the positive effect on consumption and negative effect on output and labor. Furthermore, the welfare level is lowered with the rise in the debt ratios to GDP. Thus, the optimal debt ratio should be 0.

受僱人力資源對國內經濟因素影響之研究 / A study on the causality analysis between human resources and economic indexes in Taiwan謝淑惠, Hsieh, Shu Huei Unknown Date (has links)
自全球金融風暴發生迄今,國內經濟受到國際內、外部經濟環境的影響,致使經濟成長呈現大幅下滑之情事,同時也造成國內失業率大幅成長之現象。然在面臨經濟萎縮的情境下,國內企業發展也出現些微的變化,已由投資階段轉向知識階段,在此同時人力資源也成為企業競爭的最佳利器,而且若國內企業發展呈現成長時,相對會提昇國內經濟的成長現狀。因此,本研究考量在整體產業人力需求的變化下,對於社會整體人力資源的有效運用與經濟發展的關係進行探究,
其研究結果顯示:
(1)服務業之受僱員工人數占大多數;
(2)各行業之受僱員工平均薪資間相互呈現正向相關;
(3)服務業之受僱人數對國內經濟呈現正向影響;
(4)製造業之平均薪資對國內經濟呈現正向影響;

最適負債比與效用函數中政府支出 / Optimal debt ratio and government expenditure in utility蘇子涵, Su, Tzu Han Unknown Date (has links)
有鑑於歐洲各國的福利政策與福利支出相較於其他國家高,歐洲國家多會提供窮困與殘障的人民最基本的社會保障,一般人民亦可享受到基礎醫療保障,在失業時也可以領取失業補助;歐洲各政府甚至會收購即將倒閉的企業或者提供補助使企業能夠繼續經營。然而在持續延燒的歐債危機下,為維持歐元區普遍的薪資和福利水平,歐元區內國家開始採取了國家借貸的做法,但由於國際經濟形勢不佳,歐元區經濟增量未達預期,許多國家原有債券陸續到期,若無法借到新貸款,國家將面臨倒閉危機。因此本論文主要以動態隨機一般均衡模型(DSGE),探討一個封閉經濟體系下,政府支出進入家計單位效用函數後,換言之政府支出變動將會影響家計單位消費的邊際效用,試著尋找能夠極大化社會福利的政府公債占國內生產毛額的最適比例。我們發現在提高政府公債占國內生產毛額比例時:家計單位將預期未來稅賦繳納之金額更高,因而減少消費、增加儲蓄,所以會排擠掉部分私人消費;同時政府必須提撥部分費用以支付債券利息,所以將排擠掉部分政府支出。另外隨政府公債占國內生產毛額比率上升,整體社會福利水準會逐漸下降;因此,我們認為最適政府公債占國內生產毛額比率應為零。
關鍵字:動態隨機一般均衡模型、政府支出、邊際效用、公債、國內生產毛額、社會福利水準 / In Euro zone, large spending obligations needed to support the welfare state and redistribute wealth in an effort to gain greater equality. Most European countries provide liberal social security benefits to the poor, disabled, basic medical needs and very liberal unemployment benefits. They also own and run large public companies. Under the ongoing Euro debt crisis, European governments figure out the way to maintain the high welfare level by increasing the public debt they hold. In our paper, we would like to investigate the optimal ratio of public debt to GDP by constructing a micro-based dynamic stochastic general equilibrium model (DSGE) under a closed economy. We focus on discussing the optimal ratio of public debt to GDP which maximizes social welfare in economy while putting the government expenditure into households’ utility. That is to say, the government expenditure will influence the marginal utilities of households. We find out that as a government decides to raise the debt to GDP ratio; it will crowd out both private consumption and government expenditure. Because households will expect to pay more tax in the future, they will decrease their consumption and increase their saving; high debt ratio means government should have paid more interest payment in the future. Also as the ratio of public debt to GDP rises, the social welfare becomes lower. Thus, in our findings, the optimal debt ratio to GDP should be 0.
