Un modello econometrico regionale "globale" per il mercato del lavoro italiano / A "Global" Regional Econometric Model in the Italian Labour Market

BARBIERI, LAURA 23 May 2008 (has links)
Partendo dalla constatazione della sempre maggiore complessità del contesto economico e sociale nazionale ed internazionale, imputabile da un lato al processo di integrazione economico e monetario europeo, e dall'altro alla progressiva decentralizzazione dei poteri a livello regionale, la tesi intende proporsi come uno strumento analitico di supporto al decisore. A tal fine, in base a dati annui di fonte ISTAT-SVIMEZ per il periodo 1970-2003, viene sviluppato un modello econometrico regionale 'globale' per il mercato del lavoro italiano, estendendo un precedente modello mono-regionale proposto da Baussola (2003), ad un contesto pluri-regionale. Il modello conduce non solo a rappresentare soddisfacentemente i mercati regionali italiani, ma opera altresì efficacemente nel ricostruire i valori delle variabili a livello nazionale. Il modello si conferma robusto ed efficace nel rappresentare le realtà regionali, anche nell'ottica di analisi propria dell'econometria delle serie storiche. / The starting point of this thesis is the remark that recent decades have been characterized by a rising complexity in the economic and political context both at the national and international level. This is due both to the European economic and monetary integration process and to the regional decentralisation process. With the aim of providing a useful tool of analysis for the decision-maker,. a 'global' regional model for the Italian labour market has been constructed on the basis of annual data from ISTAT-SVIMEZ over the 1970-2003 period. This model could be viewed as an extension to a multi-regional framework of the previous one-region model developed by Baussola (2003). The model shows good performance not only in representing regional labour market specificities, but also in reproducing national variable values. It is also robust and effective in a time-series context.

兩岸三地股價指數期貨連動性之研究 / The Study of Relationship among The Stock Index Futures in Taiwan, China and Hong Kong

蕭宥榛 Unknown Date (has links)
本篇探討在2010年4月16日滬深300股指期貨正式上市到2012年9月18日止的連續近月每日收盤日資料,進行區域內金融期貨市場連動關係的研究,試圖發現兩岸三地之股價指數期貨市場在亞太地區的金融主導地位,以作為國內外投資者在區域內的投資決策參考。 實證結果顯示,從共整合及向量誤差修正模型檢定發現,兩岸三地股指期貨具有長期均衡及短期的互動關係,因此可以視此三地為單一區域市場。在Granger因果檢定上,台股指數期貨雖無法預測恆生指數期貨,但仍明顯領先滬深300股指期貨且程度大於恆生指數期貨,或可推測兩岸因ECFA的簽訂使實體經濟的關聯性更為緊密,至於恆生指數期貨大多以金融、地產股為其主要成分,與大陸主要以實體經濟為主的金融市場,其Granger預測滬深300股指期貨的能力因此相對較弱。另由衝擊反應檢定得知恆生指數期貨為一獨立的市場,不受台灣及大陸指數期貨市場衝擊的影響;滬深300指數期貨因大陸金融市場逐漸開放,也會受到香港及台灣金融期貨市場之衝擊而產生影響;至於台股指數期貨則在兩岸三地,最易受到其他市場影響。最後由預測變異數分解檢定發現,台股指數期貨及滬深300股指期貨的波動皆易受到恆生股價指數期貨變異的影響,而恆生指數期貨在兩岸三地間之解釋能力最強,於兩岸三地間具金融主導地位。至於台股指數期貨對大陸金融期貨的影響也有突出的表現,因此若政府有心推展亞太金融中心之營運,勢必得加強區域間整合的力度,提出有利吸引外資之最政策,以增加台灣股市於國際間之競爭力。 / This study conducts analysis of regional linkage between financial futures market by examining consecutive daily closing information from April 16, 2010 (the official list date of CSI 300 index futures) to September 18, 2012. This study tries to find the financial dominance of these index futures market in the Asia Pacific region and hopefully it may be used as an investment decision reference for domestic and foreign investors. The empirical results show that from the total integration and vector error correction model tests and three places all indicate long-run equilibrium stock index futures and short-term interaction. Therefore, these three places can be viewed as a single regional market. In the Granger causality test on the TAIEX futures and Hang Seng Index futures, in spite of TAIEX futures can’t predict Hang Seng Index futures, it is significantly ahead of the CSI 300 index futures. TAIEX futures on the CSI 300 index futures even more impact than the Hang Seng Index Futures. It can explain that the ECFA has been signed and results show closely-related economy. Since the Hang Seng Index futures are mainly from financial and real estate stocks while the mainland-based financial market is mainly from the real economy, Granger predicts ability of CSI 300 index futures is relatively weak. Another test on the impulse response shows that (1) Hang Seng Index Futures is an independent market and is not affected by shocks from Taiwan and the mainland index futures markets, (2) CSI 300 index futures is affected by shocks from Hong Kong and Taiwan because of the gradually open financial markets, and (3) TAIEX futures can be seen as a potential Taiwanese dish economy because it is most vulnerable to other market influences among the three places. To sum up, the forecast variance decomposition tests show that TAIEX futures and the CSI 300 stock index futures are vulnerable to fluctuations in the Hang Seng index futures. In order words, the Hang Seng Index futures have the strongest explanatory power among the three places and shows financial dominance. The TAIEX futures also show its significant impact on the mainland China financial futures index. If the Government decides to promote the operation of the Asia-Pacific financial center and to increase competitiveness of Taiwan stock market, it will inevitably have to strengthen inter-regional integration efforts and make the most favorable policies to attract foreign investment.

台灣自行車產業與景氣循環之探討

駱俊文, Chun-Wen Lo January 1900 (has links)
自行車一詞儼然成為綠色環保的代名詞之一,台灣自行車業過去在國際間,被認定為品質粗糙的產品,在經過多年努力的情況下,台灣自行車業不斷的備受肯定,隨著近年全球暖化議題、全球性健康概念、油價飆漲、金融海嘯爆發等,諸多原因造成自行車從不被看好的代步工具,演變到現在成為休閒運動工具的轉變,其中;台灣自行車2008年的金融海嘯中,相較於其他傳統產業,不論是出口產值或是股價不降反漲,大舉逆勢成長,其中巨大(Giant)、美利達(Merida)、愛地雅(Ideal),成車製造商,近年來分別占出口前三大。 所以本研究要探討,金融海嘯爆發的前後,對台灣自行車業帶來的影響,研究資料選定為2000年1月至2013年12月間的巨大股價(9921)、美利達股價(9914)、愛地雅股價(8933)、台灣股價加權指數(TWII)、原油價格、工業生產指數的月資料,共168筆。透過單根檢定檢測資料是否為定態,利用共整合檢定確定是否含有至少一組解,搭配向量誤差修正模型檢測變數間的長短其關係,在利用複迴歸模型檢測。 研究結果顯示,巨大、美利達、愛地雅和台灣加權股價指數具有顯著關係,由於台灣自行車屬於出口導向以及中高價位產品,故全球景氣對台灣自行車業深具影響。其中,巨大和美利達除了ODM外,亦有自有品牌在全球銷售,愛地雅定位專業ODM專業代工廠,前者發展不同市場。 / The word "bicycle" has become one of the pronouns of environmental protection. In the past, Taiwan bicycling industry was treated as low-quality products internationally. With long-time effort, Taiwan bicycling industry was highly appreciated. Recently, global warming issue, cosmopolitan health sense, dramatically increased oil price, the eruption of financial crisis, and many reasons lead the bicycles have not positively evaluated as means of transportation. Now, it becomes the outdoor recreation mean. Comparing Taiwan bicycling industry with other traditional industry, it doesn't fall down but highly increase no matter export value or stock price. The manufacturer of Giant, Merida, and Ideal are the top 3 of export recently. So this study want to explore the things happened before and after the outbreak of the financial crisis that affects bicycle industry in Taiwan, research data for selected between January 2000 and December 2013, relationship between the Giant(9921) shares, Merida (9914) shares, Ideal(8933) shares, TWII, the price of crude oil, industrial production index. Through the Unit Root Test to test whether the data is the steady state or not. By using cointegration test to make sure whether contains at least one group of solutions and vector error correction model to detect the length of the relationship between variables, and using the multiple regression model to test. Results of the research shows that Giant, Merida, Ideal has significant relationship with TWII, because Taiwan bicycle are export-oriented and high price products, so the global boom has profound influence to Taiwan bicycle industry, among them, the Giant and Merida except the ODM, have their own brands in global sales, Ideal professional locate, ODM professional contract, the former develops different markets. / 摘要 I Abstract II 謝辭 III 目錄 IV 圖目錄 VI 表目錄 VII 第一章 緒論 1 第一節 研究動機 1 第二節 研究目的 3 第三節 巨大機械工業股份有限公司簡介 4 第四節 美利達工業股份有限公司簡介 5 第五節 愛地雅工業股份有限公司簡介 6 第六節 研究架構 7 第二章 文獻回顧 9 第一節 國內相關文獻 9 第二節 國外相關文獻 11 第三節 國內外文獻一覽表 12 第三章 研究方法 20 第一節 單根檢定 20 第二節 共整合檢定 22 第三節 向量誤差修正模型(VECM) 24 第四節 迴歸分析 24 第四章 實證分析 26 第一節 資料來源與處理 26 第二節 敘述統計 31 第三節 單根檢定 32 第四節 共整合檢定 33 第五節 向量誤差修正模型(VECM) 33 第六節 複迴歸模型 35 第五章 結果分析與建議 38 第一節 結果分析 38 第二節 建議 39 參考文獻 40 附錄一 巨大工業股份有限公司沿革 43 附錄二 美利達股份有限公司沿革 47 附錄三 愛地雅股份有限公司沿革 57 圖目錄 圖1-6 研究架構 8 圖4-1-1 台灣自行車業總出口產值(百萬元,美金) 27 圖4-1-2 台灣股價大盤指數(TWII,當日收盤價) 27 圖4-1-3 巨大股價(9921,當日收盤價) 28 圖4-1-4 美利達股價(9914,當日收盤價) 28 圖4-1-5 愛地雅股價(8933,當日收盤價) 29 圖4-1-6 國際原油價格(西德州,美元) 29 圖4-1-7 台灣工業生產指數 30 表目錄 表1-3 巨大公司基本資料 4 表1-4 美利達公司基本資料 5 表1-5 愛地雅公司基本資料 6 表2-3 國內外相關文獻整理 12 表4-1 資料來源一覽表 26 表4-3-1 ADF 單根檢定 32 表4-3-2 單根檢定-一階差分 32 表4-4-1 共整合檢定 33 表4-5-1 Giant & Merida 向量誤差修正模型 34 表4-5-2 Giant & Ideal 向量誤差修正模型 34 表4-5-3 Merida & Ideal 向量誤差修正模型 34 表4-6-1 自行車產業與景氣循環對巨大股價之影響 37 表4-6-2 自行車產業與景氣循環對美利達股價之影響 37 表4-6-3 自行車產業與景氣循環對愛地雅股價之影響 37

臺灣租稅誘因吸引投資效果之實證分析 / An Empirical Study on Tax Incentives and Investment Promotion in Taiwan

詹媖珺 Unknown Date (has links)
過去許多學術文獻針對租稅優惠吸引投資之效果進行實證分析,但實證結論並不一致。我國自1950年即開始實施一連串的租稅獎勵政策,時至今日,租稅減免仍是我國政府推動重大經濟政策慣用的誘因手段。為探討了解臺灣實施租稅優惠措施對投資變化之影響,本研究針對我國自民國50年代後期以來涉及租稅減免之相關法令進行整理,另為了充分量化這些租稅優惠措施,則參考國外相關實證文獻作法,建構了兩項租稅誘因指標作為虛擬變數,來追蹤自民國61年以來我國不同階段之減免稅狀態,並作為虛擬變數納入後續實證模型分析。 本研究利用相關變數之時間序列資料來探討租稅優惠對我國外人直接投資與國內私人投資之互動變化關係。研究步驟有三,首先,針對個別變數進行單根檢定,藉以確認變數的屬性,了解時間序列資料是否為衡定後,再利用Johansen共整合檢定法來估計和檢定多個變數,確認各變數間是否存在共整合關係後,以誤差修正模型來說明各變數間關係與整個變數脫離均衡關係後之動態調整情形。 實證結果顯示,就長期趨勢而言,我國實施之租稅優惠措施對吸引外人直接投資呈現負向且顯著之不良影響,另長期而言,租稅優惠誘因對刺激我國國內投資之變化確有顯著且正面助益,但影響效果之幅度不大。因此,本研究建議政府與其提供效果不明確之租稅誘因,不如致力於針對國家自身不完善的基礎建設或不穩定的總體經濟環境進行改善。 / Tax incentives have been in existence in Taiwan since 1950, and they are still very much on the agenda of the government. There is no agreement about the efficacy of incentives. Indeed there have been doubts about whether incentives have any effect on the economy since the 1950s. This has made some economists wonder why incentives are so popular despite the fact that their effects are either slight or unknow. This study conducts an empirical investigation of the impact of tax incentives on investment in Taiwan. We constructed two indexs of tax incentives which track the different types of incentives embarked upon by the government, and these indexes are then included in both foreign direct investment and private investment equations. Our testing procedure involves three steps. The first step involves tasting for the properties of the variables by conducting unit root teste. The second step involves testing for the long-run relationship between the variables using Johansen cointegration tests. And the third step involves estimating the long-run parameters and associated loading factors. The empirical results shows a significant negative impact of tax incentives on FDI, and a significant positive impact of tax incentives on private investment but the impact is slight. We suggest that rather than focusing on tax incentives, the country should concentrate on removing the factors that discourage investors such as poor infrastructural and institutions or macroeconomic instability.

聯準會模型的國際普遍性與門檻回歸應用 / The International Test and the Threshold Regressive Analysis of the Fed model

潘彥君 Unknown Date (has links)
本篇論文檢驗聯準會模型在六個亞洲市場:中國大陸、印度、馬來西亞、新加坡、台灣和泰國是否成立。我們首先檢驗共整合檢定來觀察變數之間長期的關係;另外,針對線性的指標模型,我們則檢測其是否具有非線性的門檻自回歸情形。實證結果顯示,於共整合檢定下,六個國家的股票價格、股票報酬和十年期債券殖利率具有長期共整合關係;而在非線性的TAR模型配適下,其解釋能力優於線性的AR模型。 / This paper studies the Fed Model in six Asia countries, China, India, Malaysia, Singapore, Taiwan, and Thailand. We examine the cointegraiton test for the long-run relationship and build a nonlinear threshold autoregressive model (TAR) between the long -term government bond yield, the stock index and the earning s index. Our empirical results show that such a long-run relationship indeed exists for those countries. In addition, the explanatory power of TAR model is better than linear AR model.

美國企業購併、股價及工業生產指數之共積與因果關係檢定 / Cointegration and Causality Test among Mergers, Stock Price and Index of Industrial Production in the United States of America

張秀雲, Hsiu-Yun Chang Unknown Date (has links)
本文使用共積檢定以及因果關係檢定方法,針對美國第三波購併風潮前後時期,檢定購併家數、股價及工業生產指數三個變數間的可預測性。不同以往的是,本文除了將購併風潮分段進行研究外,並以晚近由Hoornik 及Hendry(1997)以Johansen(1988)為基礎所發展的一套共積檢定法來檢定變數間的長期均衡關係,再以Toda and Phillips(1994)的因果關係檢定流程與SSW的因果關係檢定分別檢定出變數間的可預測性。 經由本文實證結果發現: (1)購併、股價及工業生產指數三個變數,在ADF單根檢定結果三變數皆呈I(1)非恆定時間數列。並進一步以共積檢定檢測出不論參變數或購併和股價兩變數模型,1967年第四季以前變數間皆有一共積關係存在,1968年以後則無任何共積關係。 (2)從因果關係檢定結果發現,三變數體系中,股價與工業生產指數兩變數間可能存在極高的線性重合現象,且子期間礙於無法取夠長的遞延期數,使得工業生產指數對其他變數的影響力無法明確地反應出來,故三變數模型無法正確的檢定購併風潮前後變數間的因果關係。 (3)在購併與股價變數間的因果關係檢定研究中發現,1948~1967年間,股價對購併存在可預測性;然而1968~1979年間,股價與購併完全不存在任何可預測性。故可知購併風潮前後,股價對購併的可預測性發生了變化,從1967年前股價可合理地預測購併活動,到1967年後股價卻完全無法預測購併的情況。 (4)對影響購併的諸多因素做進一步的考量,發現威廉法案的出現對當時購併案件有相當程度的衝擊。 從實證結果可知,以共積與因果關係檢定方法一再地證明出,購併風潮前後股價對購併活動的可預性確實發生了結構性的變化。 第一章 緒論 第一節 研究背景與動機………………………………………….1 第二節 研究目的………………………………………………….3 第三節 購併之定義及相關基本概念…………………………….4 第四節 研究架構與流程………………………………………….8 第二章 文獻回顧 第一節 理論文獻回顧……………………………………………10 第二節 實證研究文獻回顧………………………………………13 第三節 文獻回顧總結……………………………………………23 第三章 實證研究方法 第一節 單根檢定………………………………………………..24 第二節 共積檢定…………………………………………………28 第三節 因果關係檢定……………………………………………34 第四節 實證檢定流程……………………………………………40 第四章 實證結果 第一節 實證資料來源……………………………………………43 第二節 Augmented Dickey-Fuller單根檢定………………….44 第三節 共積檢定……………………………………………....49 第四節 因果關係檢定……………………………………………55 第五節 因果關係檢定結果………………………………………78 第五章 法律因素的考量 第一節 時代背景….……………………………………….……79 第二節 檢視法條之影響力……………………………………..81 第三節 從案例角度分析………………………………………..84 第四節 威廉法案的威力………………………………………..87 第六章 結論…………………………………………………………88 附錄圖表(一):各變數資料圖….………………………………90 附錄圖表(二):共積殘差項圖………………………………….93 參考文獻…………………………………………………………….96

投資等級債券信用價差外溢效果之研究-以Panel模型分析 / The Spillover Effect of Credit Spread on Investment Grade Bonds- The Panel Approach

林志彥, Lin, Chih-Yen Unknown Date (has links)
本研究目的在於探討投資等級債券信用價差是否存在外溢效果。信用價差是建構各種信用衍生性金融商品的基礎,惟目前學術界及業界都著眼在信用價差的拆解。信用價差可拆解成預期違約損失、稅的溢酬及信用風險溢酬。投資等級債券的信用價差來自於預期違約損失、稅的溢酬的部分較少,絕大多數來自於信用風險溢酬。信用風險溢酬係系統性影響信用價差的因素,此因素造成不同投資等級債券的信用價差間具有共整合的現象,進而引發外溢效果。然而並無人對於信用價差外溢效果作一深入探討。本研究利用目前學術界盛行的Panel模型的研究方法,對各種投資等級的債券的信用價差進行Panel Unit Root Tests、Panel Cointegration Tests及Panel Spillover Effect Tests,以求發現債券信用價差外溢效果存在與否的證據。 本文以iBoxx Index成份債券作為研究標的,利用Panel研究方法得到以下結論: 1.根據研究結果顯示,各種信評等級的債券的信用價差存在單根問題。 2.不同投資等級信評債券的信用價差擁有共整合關係。 3.不同投資等級信用評等的債券間信用價差外溢效果存在。且愈是相 鄰信評等級債券的外溢效果愈為顯著,例如BBB等級信用價差發生變動引發信評AAA等級信用價差變動的幅度便沒有AA等級信用價差變動引發AAA等級信用價差變動來得強烈。外溢效果係不對稱,當最高投資等級信評發生變動時,最低投資等級債券變動最為激烈;而最低投資等級信評發生波動時,最高投資等級債券發生變動的幅度就較小。 4.本研究支持不同債信評等的債券存在同向的外溢效果。 / This paper investigates the spillover effect in the investment grade bonds using the recently developed Panel Unit Root Tests, Panel Cointegrations Tests, Panel FMOLS and Panel DOLS techniques. Investment grade bonds’ credit spreads are found to be nonstationary and to be cointegrated in panels. This paper finds evidence of spillover effects.
