企業租稅規避與利益輸送 / Corporate tax avoidance and tunneling

黃暐翔 Unknown Date (has links)
本文採兩階段方式探討台灣上市櫃公司租稅規避與利益輸送(企業對關係企業放款)的關係,以及企業利益輸送行為及租稅規避對企業市值的影響。首先,企業進行租稅規避與利益輸送,Desai and Dharmapala (2006) 提出互補理論,認為租稅規避創造資訊透明度低的環境,隱藏利益輸送行為,租稅規避與利益輸送為互補關係;其次,企業租稅規避對其市值的影響有兩種解釋,傳統觀點認為企業租稅規避能提升企業市值。互補理論認為企業租稅規避,在沒有良好監督的情況容易隱藏利益輸送,租稅規避提升企業市值的效果降低。本文分析給定企業有利益輸送行為,企業租稅規避對於企業市值的影響。 本文採用2005年至2015年台灣的上市櫃公司為樣本進行分析。實證結果指出,首先,企業租稅規避與利益輸送指標關係人交易呈負相關,表示企業並非採用租稅規避隱藏利益輸送行為,不支持Desai and Dharmapala (2006) 的互補理論,反之,租稅規避與利益輸送指標關係人交易為替代關係;企業租稅規避與企業市值呈正向關係,支持租稅規避將財富移轉到企業會增加企業市值的傳統觀點。企業的關係人交易係數為顯著負相關,關係人交易會造成企業市值下降。企業利益輸送指標關係人交易與租稅規避交乘項的迴歸係數為負,亦即給定企業進行租稅規避,且企業進行關係人交易,會降低企業市值。 / This paper use two-stage approach to focus on the relationship between tax avoidance and tunneling of listed corporations, and how tax avoidance and tunneling of listed corporations affect firm value. First, Desai and Dharmapala (2006) think tax avoidance can create a less transparent environment to hide the tunneling which means that tax avoidance and tunneling stay in a complementary relationship. Second, there are two explanations about how tax avoidance affects firm value. Traditionally, tax avoidance can enhance firm value. However, based on the complementary view, tax avoidance can't enhance firm value without good supervision. This paper analyzes how tax avoidance affects firm value when tunneling happen. This paper analyzes data from Taiwan-listed corporations from 2005 to 2015 and has some results. First, tax avoidance is negatively related to tunneling variables related party transactions doesn't support the complementary view of Desai and Dharmapala (2006). On the other hand, tax avoidance and tunneling variables related party transactions are in a substitutive relationship. Tax avoidance is positively related to firm value. This result supports the traditional view that tax avoidance can enhance firm value. Related party transactions are significantly negatively related to the firm value which means related party transactions decrease firm value. The interaction of related party transactions and tax avoidance is negatively related to firm value. It means that when corporations have tax avoidance and related party transactions at the same time, the firm value will decrease.

The Adherence Level of Sustainability Disclosures and Firm Value : Empirical Study on the Impact of GRI Report’s Adherence Level in regard to Firm Value in the Manufacturing Industry in Europe.

Westerlund, Daniela January 2021 (has links)
Background: Sustainability reporting has become increasingly important for firms that want to appease their stakeholders and the society, whilst possibly increasing the corporate financial performance (CFP) of the firm. This is because sustainability disclosures currently work as the main channel for firms to inform their stakeholders of the CSR practices and environmental management carried out by the company. However, there have been various previous studies that examine the relation between corporate social performance (CSP) or the reported CSP, and CFP but not a study that would focus on GRI’s adherence level and its effect on Firm value (FV). The adherence level in the context of a GRI Report refers to the extent to which the GRI Sustainability Reporting Framework and GRI Standards have been applied to a company’s sustainability report (Global Reporting Initiative, n.d.). This study intends to examine if stakeholders can be affected by a sustainability report’s adherence ranking made by GRI, although there necessarily would not be a clear connection to a company’s actual environmental performance.  Purpose: The purpose of this study is to find out if the adherence level affects a firm’s value and how, although this classification of reports would not say anything about a company’s level of sustainability or a company’s sustainability performance. In short, the study wants to examine if stakeholders or the society surrounding a company are affected by the adherence level of a company’s GRI reporting and if this then can affect the value of the organization in any way. Aim: The aim of this research is to encourage organizations to become more transparent or elaborate regarding their sustainability practices if any significance between the adherence level and the FV can be found.  Method: This study was conducted by examining 98 European manufacturing firms’ GRI adherence levels for the years 2017 to 2019 and comparing them to respective Firm Values (Tobin’s Q) by the usage of panel data regression analysis.  Conclusion: The results show that no significant relationship between the GRI adherence level and FV can be found in the European manufacturing industry for the period 2017 to 2019.

以平衡計分卡架構探討我國資訊電子業企業價值之影響因素

陳玉芳 Unknown Date (has links)
企業價值受到資本市場的眾多投資人、公司股東或企業管理階層等等的高度矚目。企業價值評價的方法眾多,最理想之狀況是根據企業相關資訊而計算出的實質價值。然而實質價值難以估計,遂以市價(亦即股票價格或股價乘以發行股數)做為實質價值之代理變數。然而,考量不同公司,其發行在外股數多寡不一,為消除公司規模問題,本研究根據Ohlson(1995)提出之模型加以延伸,以市價/帳面價值比作為企業價值之衡量指標。 然而,企業價值究竟受到哪些因素影響呢?過去研究多偏向探討財務資訊與企業價值間之關係,一直到近期始開始注意到非財務性資訊對企業價值之影響。但仍缺少一個完整的邏輯結構,Kaplan and Norton(1992)提出的平衡計分卡提供了一個全面性整合的架構去評估組織之績效,以嚴謹的邏輯關係將財務與非財務層面之因素加以連結,透過計分卡的四個構面:財務、顧客、內部流程及學習與成長的層層推演,幫助達成組織之策略目標。而企業策略目標之達成,對於企業價值應有正面助益,故本研究以平衡計分卡之架構,討論我國資訊電子業企業價值之影響因素,探討欲提升企業價值可從哪些因素著手。 本研究以複迴歸方式進行分析,研究結果顯示:(一)財務構面的營業毛利成長率與股東權益報酬率與企業價值間有顯著正相關;(二)顧客構面的顧客滿意度與企業價值間有顯著正向關係;(三)內部程序構面的研發強度與企業價值間有顯著正相關;(四)學習與成長構面的員工生產力與員工教育程度與企業價值間有顯著正向關係。建議我國資訊電子業欲提升自身之企業價值,可從上述各因素著手努力。 關鍵字:企業價值、市價/帳面價值比、平衡計分卡 / Valuation of the firms is a considerable issue for investors, stockholders, and managers. The valuation methods are numerous, the most ideal one is intrinsic value which is calculated on the firm’s related information, such as dividend policy, profitability and growth etc. However, it is difficult to calculate the intrinsic value. The related research always substitute market value (stock price or stock price*outstanding shares) for intrinsic value. Considering the firm scale, this research followed the Ohlson model (1995), and chose the price-to-book ratio (P/B ratio) as the measure of the firm value. Anyhow, what are the critical factors influencing firm value? Most past researches focused on the relationship between financial information and firm value. Currently, the influence of non-financial information factors begins being emphasized. Yet, it still lacks a set of complete logical structure. “Balanced scorecard”, presented by Kaplan and Norton (1992), provides an integrated enterprise performance evaluation system. This tool logically connects the financial and non-financial factors and divides all the influential factors into four different “scorecards”, including “finance”, “customer”, “internal process” and “learning and growth”, in order to help the organization achieve its strategic objectives. Furthermore, the achievement of strategic objectives is supposed to have positive effect on organizational performance. Therefore, this research explores the influential factors toward firm value, utilizing “balanced scorecard”, and probe which factors can clearly increase the firm value. The research target sample is the information technology industry in Taiwan. The statistical analysis method in this research is multiple regressions. The research results are as follows. 1. In the finance perspective, “gross profit growth rate” and “return of equity” positively affect the firm value. 2. In the customer perspective, “customer satisfaction rate” positively affects firm value. 3. In internal process perspective, “research and development (R&D) intensity” positively affects the firm value. 4. In learning and growth perspective, “employees productivity” and “employees education level” positively affect the firm value. Hence, this research suggests the information technology industry in Taiwan can aim at the concluded factors to increase its firm value. Key words:firm value, price-to-book ratio, balanced scorecard

經理人自信程度與公司績效 / The confidence level of CEOs and the performance of firms

李孟玲, Lee, Mengling Jannies Unknown Date (has links)
Anand M. Goel and Anjan V Thakor 於最近的財務學刊中提出理性且風險趨避的經理人會放棄部分正報酬但風險高的投資,造成投資不足問題,使得公司價值未能極大化。然而,極端過度自信的經理人投資正負報酬皆有的計畫,造成過度投資,使得公司價值遞減。只有中度自信的經理人能為公司價值帶來極大化效果。本篇研究採用台灣上市櫃公司近二十年資料,以公司經理人對公司持股的變化來衡量其過度自信的程度,探討公司經理人自信程度對公司獲利能力與公司價值的影響。實證研究發現,極端過度自信的經理人與極端保守的經理人使公司的績效與成長性減少,降低公司價值。此研究增加我們了解經理人自有特徵對公司價值的影響,並為公司理財課題帶來新的貢獻。 / Former literature theorized that excessively overconfident CEOs and excessively diffident CEOs reduce the firm value for underinvestment and overinvestment problems and moderate overconfident CEOs willing to take risky but positive NPV projects increase the firm value. This paper conducts an empirical research by using the change of purchase and sale on own company stocks took by CEOs to measure CEO overconfidence level in Taiwanese listing companies and find that the profitability and stock performance of firms led by excessively overconfident CEOs and excessively diffident CEOs decrease compared to by moderate overconfident CEOs. The result contributes to the understanding of the impact on firm valuation by CEO idiosyncratic characteristics and offers new evidence to behavior finance on corporate management.

權益薪酬會影響審計委員會監督關係人交易之效果嗎? / Does Equity-based Compensation Affect Audit Committee Supervision on Related Party Transactions?

黃玉如, Huang, Yu Ru Unknown Date (has links)
本文主要探討權益薪酬對審計委員會監督關係人交易效果之影響。本研究從美國證券交易所公開資訊EDGAR資料庫以手動蒐集關係人交易資訊,以2010年至2013年間之中小企業為樣本進行實證分析。實證結果發現關係人交易與權益薪酬交乘項與企業價值呈現顯著負相關,意即發放權益薪酬使得審計委員會極大化個人利益而過度注重短期財務績效,選擇默許管理階層不當之關係人交易安排,進而造成企業價值不利之影響。額外分析亦指出審計委員會之權益薪酬對其監督關係人交易效果有負面影響,但未發現證據指出審計委員會之現金薪酬與其監督關係人交易效果有關聯性。 / This study investigates whether equity-based compensation for audit committee members is associated with the effectiveness of their supervision on related party transactions. We hand collect the data of related party transactions for small and medium-size firms from EDGAR database for the period 2010-2013. We find that the interaction effect between related party transactions and stock compensation for audit committee members is negatively associated with firm value. It suggests that in order to maximize short-term benefits, audit committee members with stock compensation are inclined to be more tolerable to earnings management through related party transactions that are unfavorable to shareholders. Additionally, we do not find any evidence indicating that cash compensation is associated with the effectiveness of audit committee’s oversight on related party transactions.

智慧資本與公司價值關係之實證研究

周宜勇, Chou, I-Young Unknown Date (has links)
在知識經濟時代中,企業的核心競爭價值已由過去以勞力、廠房及資本等有形資產為基礎,轉變至以智慧資本驅動為核心。然而,受限於會計準則對於智慧資本認列及評價規定之缺乏,僅以財務、實體資產衡量企業價值已不足以反映企業的真實價值。因此,本研究以人力、創新、流程及顧客資本等四大構面,選擇攸關價值因子之替代變數,從投入及產出觀點探討這些價值因子及價值因子間之相互效果對於企業價值的創造是否具有正向關係。 本研究根據Ohlson(1995)的評價模型作為理論架構,以2000年至2002年間台灣上市公司為研究對象,選擇以員工相對教育程度、專利權件數、資產週轉率及顧客留存率等作為智慧資本價值因子,並採用複迴歸方式從事當期及遞延一期之實證模型分析。 實證結果顯示,就智慧資本價值因子而言,員工相對教育程度、專利權件數及資產週轉率均與企業當期及遞延一期之市場價值具有顯著正向關係,惟專利權件數的遞延效益並不穩定。就價值因子間之相互作用而言,人力資本與創新、流程及顧客資本間及創新資本與顧客資本間所產生之綜效,與企業價值間具有正向關係,然而僅人力與創新資本間之綜效具有明顯之持續性。此外,創新與流程資本間之綜效,對於企業價值之創造則具有落後現象。 根據實證結果,本研究建議企業從事知識管理活動時,除應瞭解各項智慧資本對企業核心價值之貢獻外,並應重視智慧資本價值因子間之相互效果,俾利結合企業的經營策略,提昇其市場價值。 關鍵字:智慧資本、Ohlson模型、企業價值、相互效果 / In the era of knowledge economy, firm’s core competitiveness has changed from tangible assets which include labor, factory buildings and capital to the intellectual capital value-drivers. However, the lack of accounting standards of recognition and valuation of intellectual capital results in failing to reflect the firm’s intrinsic value. Therefore, this study uses dimensions of human capital, innovation capital, process capital and customer capital to select the alternative variables of relevant value factors and to examine the relationships between intellectual capital value factors, inter-effects in those value factors and firm’s market value from an input-output viewpoint. The framework of this study is based on Ohlson(1995)valuation model, and the samples of this study is the listed public companies in Taiwan during 2000 to 2002. This study uses relative education degree of employees, patents, assets turnover rate and customer retention ratio as the intellectual capital value factors, and adopts multiple regression methods to build the current and lagged one period empirical analysis models. As the intellectual capital value factors, the results show that relative education degree of employees, patents and assets turnover rate have significant positive effect on firm’s market value under current and lagged one period model. But lagged effect of patents is not stable. As the inter-effects of value factors, the results show that there are significant positive relationships between the synergies of human-innovation, human-process, human-customer, innovation-customer capital and the firm’s market value, but only human-innovation capital has a remarkable persistence. Furthermore, the synergy of innovation-process capital has a lagged effect on the firm value creation. According to the result, this study suggests that company should not only understand the contributions of every intellectual capital value factor to its core value, but also pay more attention to their inter-effects for integration of the firm’s operation strategies and increasing market value. Key words:Intellectual capital, Ohlson model, firm value, inter-effects

The study examines the short- and the long-term impact of SWF investments on publicly traded companies, performed with an event study methodology to estimate the abnormal returns of the stock prices of the acquired firms around the dates when the announcements become publicly available. The announcements included in this study were made between 1990 and 2015. First, the results are compared to the level of transparency, as measured by the LTMI Index, to examine how the changes in stock prices react to the event. Then, the study presents six extensions with portfolios for IFSWF membership, SWF funding source, open market transactions and privately negotiated deals, domestic and foreign targets, deal value and acquired target stake. The results of the study provide empirical evidence of short-term significant cumulative abnormal returns and that SWFs with high transparency tend to generate more and positive cumulative abnormal returns, while SWFs with low transparency generate negative cumulative abnormal returns. Moreover, the long-term results suggest negative cumulative abnormal returns, though mostly insignificant, and show a tendency to mean revert. / Este é um estudo sobre o efeito do preço das ações sobre investimentos anúnciados pelos fundos soberanos (SWFs). O estudo examina o impacto a curto e a longo prazo dos investimentos dos fundos soberanos em empresas de capital aberto, através de estudo de evento para estimar os retornos anormais dos preços das ações das empresas adquiridas em torno das datas em que os anúncios são públicos. Os anúncios incluídos neste estudo foram feitos entre 1990 e 2015 sendo que, em primeiro lugar, os resultados são comparados com o nível de transparência, medida pelo índice de LTMI, de forma a analisar possíveis alterações nos preços das ações face ao anúncio. Posteriormente, o estudo apresenta seis extensões: portfólios da IFSWF, fonte de financiamento dos SWFs, com investimentos privados e públicos, investimentos em empresas nacionais e estrangeiras, valor do negócio e percentagem adquirida. Os resultados do estudo fornecem evidência empírica dos retornos anormais acumulados significativos a curto prazo e que, os fundos soberanos com elevada transparência, tendem a gerar maiores retornos anormais acumulados ao passo que os SWFs com menor transparência geram retornos anormais acumulados negativos. Além disso, os resultados a longo prazo sugerem retornos anormais cumulativos negativos, embora na sua maioria insignificantes, apresentando uma tendência da reversão da média.
