The share of corporate saving in total saving in South Africa has increased during the past four decades. In this dissertation various economic theories are examined in order to try to explain this change and to determine the possible implications of this change. The conclusion is that the relationship between the investment decision of companies and their savings decision is governed by the determinants of the financing choice of firms. These include cost, risk, control and availability. If, because of these factors, firms prefer to finance investment with retained earnings, there is a relationship between investment and the level of corporate saving. The degree to which the investment decision is dependent on the availability of internal financing will determine the importance of the level of corporate saving in a country. / Oor die afgelope vier dekades het die aandeel van maatskapybesparing in die totale besparing in Suid-Afika toegeneem. In hiersie vehandeling word veskillende ekonomiese teoriee ondersoek ten einde hierdie verandering te probeer veklaar en te probeer vasstel wat die implikasies van hierdie veandering is. Die gevolgtrekking waartoe gekom word, is dat die verband tussen die investeringsbeleid en die maatskappye se besparingsbesluit bepaal word deur faktore wat die finansieringskeuse van die firmas beinvloed, naamlik koste, risiko, beheer en beskikbaarheid. Indien hierdie faktore daartoe lei dat die maatskapye verkies om investering met terruggehoue bespaaring the finansier, is daar 'n verband tussen investering en die vlak van maatskappybesparing. Die mate waarin die investeringsbesluit afhanklik is van die beskikbaarheid van interne finansiering, sal bepaal hoe belangrik die vlak van maatskappybesparing in 'n land is. / Economics and Management Sciences / M.Com.

本研究所稱建商包括「建設公司」以及有從事建設業之「資產股公司」。建設公司在一般人的認知裡是高獲利的產業，但其營運狀況易受到房地產景氣波動的影響，發生財務危機的比例較其他產業高；而資產股公司投入建設業被認為是挹注獲利拉高股價的題材，因此本研究探討1996-2007年建設公司利潤力績效與房地產景氣的關聯性，獲利較同業佳的建設公司類型、投資決策之差異為何，以及資產股公司從事建設業獲利與房地產景氣之關聯，使建商能根據所發佈之房地產景氣指標在投資決策上做適當之調整，也提供投資人投資建商之參考。研究結果如下： 一、前期房地產景氣越好，建設公司利潤力績效越佳，總銷與購地總額越高。 二、市場佔有率高、建設營收比＞90％的建設公司利潤力績效較佳。借殼上市、曾發生財務危機、上市公司相較於上櫃興櫃公司利潤力績效較差。產品純住宅較產品包含辦公室、廠辦的公司獲利差，但並不明顯。此外，推案區位並非影響建設公司獲利之因素。 三、獲利較佳的建設公司較能夠敏銳掌握房地產景氣趨勢推案，並在景氣較差時敢於持續購地，景氣好時也積極購地。 四、資產股公司多數個案選擇在房地產景氣燈號綠燈時推出，銷售情形佳，貢獻獲利良好。大型商業開發案開發、獲利情形與房地產景氣的關係可能不如一般建案密切。近期開發案除了住宅建案，還有辦公、商場、商務住宅等商業不動產，長期租金收益的開發概念增加，較早期開發多元化。 / The real estate developers in this study included “construction companies” and the “property stock companies” which operate construction businesses. Construction companies are commonly known as a high-return industry by the general public, but their operations are easily affected by real estate cycle and their chances of financial crisis are higher than other industries. It is considered a sure bet for pushing up the share prices when property stock companies participated in the construction industry. This study analyzed the relationship between the profit performances of construction companies and the real estate cycle, the types of relatively high profitability construction companies in the industry, the differences in investment strategies and the relationship between property stock companies’ gain of profits from construction business and the real estate cycle in 1996-2007. This is to enable real estate developers to make appropriate strategic adjustment on their investment according to the announced real estate cycle indicators, and to serve as a reference for the investors on investing in construction companies. The results of the study are as follows: 1.The better the real estate cycle in the previous year, the better the profit performance of construction companies, with higher total sales and total land-purchase amount. 2.The construction companies with higher market share and construction-revenue ratios higher than 90% have better profit performances. The profit performances of backdoor listed companies, companies with previous financial crisis and TSE listed companies are not as good as OTC and emerging-market listed companies. Companies providing purely residential products have poorer profit performances than those providing offices and factory space alongside with residential products, but the difference is insignificant. Apart from that, project location does not affect the profitability of the construction companies. 3.Construction companies with better profits can get hold of the real estate cycle in a relatively fast way. They also can continue to buy land when the real estate cycle is depressing and to actively buy land when the real estate cycle is good. 4.Most projects of property stock companies were released when the real estate cycle signal turned green. Good sales contributed to good profitability. The relationship between large commercial development project profitability and the real estate cycle might not be as close as general construction projects. Apart from residential projects, recent development projects also include commercial real estates such as offices, shopping malls, residential-commercial buildings, etc. The development concept of long-term rental return is more popular and it has more variety than the initial period.

Trata-se de uma pesquisa de conceitos que possa apoiar o processo decisório sobre investir ou não em projetos de TI, buscando embasar e agregar transparência aos atos de investimentos feitos com recursos de órgãos governamentais, propondo a criação de padrões e disponibilizando a documentação sobre as decisões tomadas. Mesmo havendo o foco inicial voltado as ações da gestão pública, a metodologia aqui proposta não se limita a este setor, podendo ter sua aplicação estendida ao ambiente da iniciativa privada. Neste contexto de execução do processo decisório, buscam-se conceitos de gestão, intentando agregar qualidade aos serviços entregues, qualificando as decisões sobre os investimentos que possam ser feitos em projetos de criação e atualização de ambiente de informação. Durante o desenvolvimento desta pesquisa houve a interação com agentes executores de serviços públicos, levantando requisitos a serem atendidos e partindo-se destas definições se realizou a busca de referências teóricas que apoiassem as propostas de análise, estudando metodologias, ferramentas e técnicas direcionadas ao processo decisório. Foi definido o caminho de construção das análises aplicando-se os passos da metodologia Design Science Research (DSR), construindo-se artefatos a partir das teorias compiladas, proporcionando a materialização das ações através da utilização dos fluxos e telas desenhadas, criando assim, um processo metodológico que apoia a decisão de execução do investimento e que também padroniza, documenta e agrega agilidade ao seu desenvolvimento. / This study aims to create a methodological proposal for the evaluation of investments in Information Technology assets related to the public management sector through the collection and compilation of techniques, methods and tools for this purpose. It is a concept research that can support the decision-making process about whether or not to invest in IT projects, seeking to base and aggregate transparency on the actions of government agencies, proposing the creation of standards and making documentation available on taken decisions. Even though the initial focus is on public management actions, the methodology proposed here is not limited to this sector, and its application can be extended to the private sector environment. In this context of execution of the decision-making process, management concepts are sought, trying to add quality to the delivered services, qualifying the decisions about the investments that can be made in projects of creation and updating of information environment. During the development of this research there was interaction with public service agents, raising requirements to be met and starting from these definitions, the search for theoretical references was made to support the analysis proposals, studying methodologies, tools and techniques directed to the decision-making process . It was defined the way of construction of the analyzes by applying the steps of the Design Science Research (DSR) methodology, constructing artifacts from the theories compiled, providing the materialization of the actions through the use of the flows and drawn drawings, creating, a methodological process that supports the decision to execute the investment and also standardizes, documents and adds agility to its development.

Com a intensificação da competitividade do mercado, empresas que realizam escolhas equivocadas podem comprometer significativamente sua atuação. Portanto, para se destacar dentre as demais, decisões não mais podem ser intuitivas e perdas tornam-se inadmissíveis. Sob o aspecto financeiro, a análise apropriada de projetos de investimento é fundamental para o crescimento solidificado da firma. Quando questionados sobre a implantação de determinado projeto, gestores adeptos de diferentes métodos de análise de investimento tendem a tomar a mesma decisão. Porém, ao depararem-se com uma diversidade de projetos de investimento, métodos usuais de análise de investimento causam divergências, conturbando o processo decisório. Ao priorizar algum projeto de investimento, aparentemente atraente economicamente, em detrimento de outros, a firma pode vir a sofrer prejuízos financeiros, decorrentes de características relevantes desconsideradas pelos métodos usualmente utilizados. A partir da análise crítica de métodos determinísticos, métodos que apreciam a incerteza e métodos que consideram a flexibilidade dos projetos, tornou-se factível a retificação da tomada de decisão na comparação entre investimentos. Assim, adequações dos métodos usuais de análise de investimento foram apresentadas como forma de conduzir a resultados mais eficientes. Nesse sentido, o presente trabalho desenvolve os conceitos de valor presente líquido equivalente (VPLE) e taxa interna de retorno equivalente (TIRE), como métodos determinísticos voltados exclusivamente para a tomada de decisão diante de diversas opções de investimento. Em seguida, com a flexibilização de tais conceitos, determina-se o conceito de opções reais equivalentes como principal ferramenta para a comparação parametrizada de projetos de investimento. Para a verificação de sua contribuição na análise econômica, um estudo de caso foi realizado e seus resultados comparados com aqueles esperados pelos métodos tradicionais. Logo, concluiu-se que, ao avaliar projetos sob as mesmas condições de contorno, diferentes ferramentas levam a semelhantes resultados. Porém, a parametrização das variáveis e a flexibilização permitida pelas opções reais equivalentes adicionam valor ao investimento e, conseqüentemente, à empresa. / Considering the increasing level of competition of many markets, companies that take wrong decision choices for their businesses may compromise its performances. Therefore, in order to reach better performance than its competitors, the decisions should not be based on intuition and unnecessary losses become unacceptable. Under the financial scope, the appropriate analysis of investment projects is essential to promote a solidified growth of a firm. When asked about the implementation of some project, managers that make use of different methods of investment analysis tend to take the same decision choice. However, when the situation involves a variety of investment projects, the usual methods of investment analysis can imply in different results, disturbing the decision process. When any investment project considered apparently more economically attractive is put up front in any company\'s choice, the ones that are taking this decision may suffer financial losses due to some important issues not considered by the usually methods used. By using a critical analysis of deterministic methods, methods that assess the uncertainty and methods that consider some flexibility of projects, it becomes of major importance to apply some decision-making process to compare the possibilities of investment projects. So, some arrangements in the usual methods of analysis of investment were presented in order to reach more efficient goals. That is the reason that this research development the concepts of equivalent net present value (ENPV) and equivalent internal rate of return (EIRR), as deterministic methods used exclusively to the decision making with a variety of investment projects. After this, with the flexibility of this concepts, it is established the concept of equivalent real options as it main tool to make a parameterized comparison of investment projects. To prove its contribution to the economic analysis techniques, it was set an application of the proposed methodology and its results were compared to the ones obtained if the traditional methods. Therefore, this paper work got the conclusion that, if analyzed investment projects under the same conditions, different tools generate similar results. However, the same parameters and the flexibility given if used Equivalent Real Options adds value to investment and, consequently, to the company.

我國自民國87年起實施「未分配盈餘加徵10%營所稅」，已有多位學者研究兩稅合一稅制與企業投資之關係，但針對未分配盈餘加徵稅負對企業投資意願的影響，迄今尚未有以『實際加徵之稅負資料』進行實證研究探討。本研究以未分配盈餘加徵稅負對企業投資支出之影響為主軸，並進一步分析當『產業』不同或『公司規模』大小不同時，未分配盈餘加徵稅負與企業投資的關係。除此之外，將企業投資分為固定資產總額投資、固定資產淨額投資及研究發展支出。 實證結果發現：(1) 未分配盈餘加徵稅負與固定資產投資及研究發展支出之迴歸係數為負值，且當投資為固定資產投資總額及固定資產投資淨額時，達統計上的顯著性。且由數據發現，電子產業研發費用較非電子產業高出5倍之多，因其仰賴高額研發支出，故需較多保留盈餘以因應投資需求；實施未分配盈餘加徵稅負後，電子產業實際加徵之未分配盈餘稅負較非電子產業為高，因此當政府增加未分配盈餘加徵稅負之制度，對電子產業衝擊較大。 (2) 由樣本超過200間的五大產業中發現，其投資支出與未分配盈餘加徵稅負的迴歸係數大致呈負值，且電機機械業、電子產業及建材營造業的迴歸結果達統計上的顯著性。(3) 本研究將企業依總資產規模不同分為四大組，發現當公司規模最小與公司規模最大時，此兩個組的企業，未分配盈餘加徵之稅負愈高，其固定資產投資之金額愈低。上述未分配盈餘稅負與投資的關係，可發現多數企業視未分配盈餘租稅成本為重要之投資決策考量因素，此一研究結果可提供政府制定稅務政策之參考。

本文建立一公司稅、累進個人稅、非債稅盾和破產可能之不確定經濟模型，探討公司的投資理財決策行為。和以前文獻最大的不同點，在於公司風險債利率水準明顯且完全的內生化處理，此內生化利率不僅受公司舉債額度的財務決策影響，也會反應公司現行投資或資本存量的實質決策，模型中的財務和實質決策具有完全互動之特性。 累進個人稅下，只要存在一組投資人間的邊際稅率結構，能排除套稅資產配置，則市場無套稅價格和競爭均衡便存在。此一結果，使本文模型中的資產評價得以建立於競爭財務市場均衡的基礎。市場均衡下，公司債利率會隨公司舉債額度而同向、投資額度而反向調整，此時股東與債權人間的代理成本問題完全消失、市場具有公平保護債權人的機能。如果公司債利率外生而無法依市場均衡評價，則由於代理成本問題存在，使公司最適投資相對低於、舉債額度則高於利率內生之最適水準。另外，傳統一些稅制分析法的資本結構決定理論，只是本文之特例。 稅盾變化，如投資減免率或定額減免等，對公司最適投資和舉債的影響，除以前文獻之結果外，還包含一利率回饋效果，後者可能改變以前文獻之結論。例如，本文發現獎勵投資之折舊率或投資扣抵的政策美意，可能反而造成抑制投資的結果，本文這部分之結論，或可提供有關公司資本結構決定之實證研究新的詮釋，另外在稅制設計上亦具政策上的含意。

O estabelecimento de uma relação entre estes preços limite e volume só pode ser explicado através das teorias da área de Finanças Comportamentais, que através do relaxamento de premissas como racionalidade do consumidor e mercados eficientes se propõem a uma maior adequação à realidade. Os teste realizados confirmam haver utilização do preço mínimo das últimas 52 semanas, por parte do investidor, como referência para a tomada de decisão, ocasionando um aumento, acima de mercado, do volume de negociação destas ações no momento em que o preço corrente extrapola o preço mínimo passado. Entretanto, esta mesma relação não foi identificada para o preço máximo das últimas 52 semanas. A identificação de mais esta variável para explicar variações no volume de negociações do mercado de capitais no Brasil contribui tanto para as recentes teorias de Finanças Comportamentais como para o próprio desenvolvimento do mercado financeiro e conseqüentemente do país, sendo, portanto, do interesse de todos. / This academic work studies variables that explain the capital market volume in Brazil, focusing on the last 52-week minimum and maximum prices. The establishment of a relation between the market volume and some past prices can only be explained through Behavioral Finance theories, which abandon some strong premises as rationality and efficient markets to better adapt to reality. All the statistical tests made confirm that investors, in Brazil, make use of the last 52-week minimum prices to take buy-sell decisions. Because of that, we are able to observe that during the weeks where the current prices are below the last 52- week minimum prices, the volume goes up. Unfortunately it was not possible to confirm the same phenomenon for the last 52-week maximum prices. The identification of this other variable to explain the capital market volume in Brazil provides a huge contribution to the area of Behavioral Finance as well as to the capital markets development itself, leading to a further economic growth for the country, an issue of general interest for all of us.

Information plays a significant role in the success of investment strategies. Within a non-advisory context, individual investors elect to build and manage their investment portfolios to avoid the cost of hiring professional advisors. To cope with markets’ uncertainty, individual investors should acquire, understand, and use only relevant information, but that task can be affected by many factors, such as domain knowledge, cognitive and emotional biases, information overload, sources’ credibility, communication channels’ accuracy, and economic costs. Despite an increased interest in examining the financial performance of individual investors in Saudi Arabia, there has been no empirical research of the information behavior of individual investors, or the behavioral biases affecting the investment decision making process in the Saudi stock market (SSM). The purpose of this study was to examine this information behavior within a non-advisory contextualization of their investment decision-making process through the use of an online questionnaire instrument using close-ended questions. The significant intervening variables identified in this study influence the individual investors’ information behavior across many stages of the decision making process. While controlling for gender, education, and income, the optimal information behavior of individual investors in the SSM showed that the Experience factor had the greatest negative effect on the Information Seeking Behavior of individual investors. This was followed by Risk Tolerance, Financial Self-Efficacy, Emotional Biases, Education Level, Formal Information Access, Regret Aversion Bias, and Subjective Financial Knowledge. The Information Acquisition and Information Searching Behavior was influenced by the Acquisition Skepticism, Regret Aversion Bias, Formal Information Access, Overconfidence, and Information Seeking Behavior. Furthermore, the findings indicate that Formal Information Sources have a statistically significant positive effect on the Information Seeking Behavior, and on the Information Acquisition and Information Searching of individual investors in Saudi Arabia. Finally, the Socioeconomic Status (SES) of individual investors in Saudi Arabia was significantly influenced by the employment status, work experience, age, marital status, and income.
