This paper empirically examined adjustment costs influence on dynamic rebalancing behavior of capital structure of Brazilian listed companies from 1999 to 2007. Leverage ratios were presented under three different scenarios, considering fixed costs, proportional costs and a composition of fixed and proportional costs using a simulated reduced model of the capital structure. A non-parametric data analysis reveals that companies present a dynamic behavior in its financing decisions of capital structure adjustment, but that is far from continuous. A duration model proved to be the best choice to measure time between companies’ capital structure adjustments. Results are strongly relevant and support the theory of companies’ dynamic rebalancing behavior around an optimal range. However, adjustments do not occur immediately and the persistence shocks to capital structure accounts in its great part to adjustments costs instead of a possible indifference toward capital structure. This is a pioneer paper accounting for a djustment cost of capital structure in Brazilian market, which makes room for discussion around optimal capital structure on Brazilian companies. / Diversos estudos de Finanças Corporativas consideram os custos associados aos ajustes da estrutura de capital das empresas irrelevantes tanto na forma quanto em magnitude. Este estudo analisou empiricamente a influência dos custos de ajustamento na dinâmica dos ajustes da estrutura de capital de empresas brasileiras de capital aberto no período de 1999 a 2007. A alavancagem foi abordada sob três diferentes cenários, considerando a presença de custos fixos, custos proporcionais e por uma composição de custos fixos e proporcionais através de simulações utilizando um modelo reduzido da estrutura de capital. Em seguida a análise não paramétrica da amostra revelou que as empresas apresentam um comportamento dinâmico em suas decisões de financiamento para o ajuste da estruturas de capital, mas que não se revelou contínuo. A utilização de um modelo de duration mostrou-se adequado para mensurar o intervalo de tempo entre os ajustes da estrutura de capital das empresas. Os resultados são extremamente relevantes e suportam a teoria de um comportamento de rebalanceamento dinâmico pelas empresas de suas estruturas de capital em torno de um intervalo ótimo. Entretanto os ajustes não ocorrem de forma imediata e a persistência de choques à estrutura de capital deve-se em sua maior parte aos custos associados aos ajustes do que a uma possível indiferença à estrutura de capital. . Este trabalho constitui-se como pioneiro no mercado brasileiro acerca dos custos de ajustamento da estrutura de capital e abre espaço para a discussão do comportamento ótimo em torno da estrutura de capital de empresas nacionais.

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.

The main objective of this study was to test if the applicability of known capital structure theories holds water in abnormal economic environments, in particular, in Zimbabwe. Using secondary data collected for listed manufacturing firms from 2009-2018, results from a fixed effects regression model concluded that profitability, company size, non-debt tax shields, firm liquidity, inflation and GDP were significant in explaining capital structure decisions in Zimbabwe. In the context of South Africa, company size, asset tangibility, firm liquidity and inflation were found to be significant. The pecking order and trade-off theories were the only two theories that were found to be applicable in the Zimbabwean context, and the application of both theories indicated the use of internally generated funds as opposed to external finance sources, such as debt and equity. These results attribute to the abnormality and instability of the Zimbabwean economy, especially with regards to limited access to capital. / Business Management / M. Com. (Business Management)

生技產業為我國未來六大明星產業之一，除政府成立生技創投基金，民間企業也陸續加入這波生技投資行列，如永豐餘集團旗下的上智生技創投，與潤泰集團旗下的鑽石生技投資。以籌資來源而言，又分為借款融資關係(負債端)的外部資金，以及股東投資關係(權益端)的自有資金兩種，對於公司經營各有優缺點，亦應取得平衡。唯目前多數為權益端的資金投入，尤其以該產業中風險最高的新藥研發公司為例，仍普遍高達95%以上的股東權益比率。顯示其籌資來源有限，且難以吸引負債端的投資者參與。而這樣的資金來源比例，除不符合企業融資順位理論於公司成長階段的籌資策略與負債權益比率，權益端資金多以短期獲得高利潤為目的，以資金性質亦不適合占資產達95%以上之比例。 以目前負債端籌資管道，新藥研發公司多數利用台灣中小企業信用保證基金直保部或經濟部促進產業創新或研究發展貸款計畫專案申請，唯融資額度上限遠不足以支付藥物開發費用，且非一般負債端直接經由銀行評估取得融資之方式。綜觀國際業態，單一全新藥物開發至上市平均需約USD8億元(約NTD240億元)不等，而台灣公司的研發策略多數為分段發展或老藥新用(藥物重新定位)策略，但仍有高度資金需求。唯銀行、負債端投資者普遍缺乏投入該產業的意願，主要顧慮為具冗長的產品研發週期業態、高度不確定性的產品上市審查、長期臨床試驗伴隨的高額成本。此外，對於資金專注研發之新藥研發公司，亦面臨擔保品不足之問題。而實務上，負債端資金提供者如銀行，對於複雜的生技領域與新藥研發公司業態不甚了解，為降低融資意願的另一主因。 故本研究旨在建立一套適用於新藥研發公司之一般性價值評估方式，解決此雙方認知差異問題，以增加更多元的籌資管道。其中，本文參考其他國家評估方法，選擇其中針對技術型公司、發展久遠的韓國技術信用保證基金KOTEC評估模式，導入台灣微脂體、基亞生物科技、賽德醫藥科技3間新藥研發公司個案作一評估。並於最後研究結論，經由分析比較個案公司間歷年經營狀況，得出公司整體與個別質、量性指標項目量化的相對分數，以台灣微脂體分數157分最高，基亞生技次之。本研究亦參考個案評估狀況，得出該類公司較佳的一般性經營策略結論，發現公司創立早期可先以開發週期短、風險較低的老藥新用開發以代替副業產生短期營收的效用，同時累積本業開發經驗，待時機成熟再轉入全新藥物開發為一攻守兼具的經營模式，以供新藥研發公司參考。此外，本研究屬於探索性研究，僅於評估新藥研發公司分數階段，尚未轉換為公司融資評等。該部分尚待具一定案源量後，以統計模型將評估分數與還款違約率關聯性做一分析，方能計算融資評等。而建立內部評等模型、資訊系統對台灣銀行規模而言，為一額外高昂成本，亦建議可效法韓國由政府主導為可行方式之一。 / The biotechnology industry is one of the six future stars of the industries in Taiwan. The government established Biotechnology Venture Capital (BVC), and the more and more private companies joined the procession of biotech investments, such as the two famous biotech funds, Taiwan Global BioFund (TGB) and Diamond BioFund Inc.. According to sources of funding, we can divided them into two groups: one is the loan of external funds (liability side), and the other is the shareholder investment of internal funds (equity side), both of them have different advantages and disadvantages for the company, and the company should strike a balance between these advantages and disadvantages. However, the majority of the funds are invested from the equity side, especially the new drug development companies, which are the highest risk types in the industry, and most of their equity ratio is higher than 95 %. This information indicates the limited sources of funding, and the difficulty to attract liability side’s investors to participate. That proportion of funding sources doesn’t comply with the company’s financing strategy and debt to equity ratio in the growth stage of the enterprise life cycle in the pecking order theory, and equity side’s funds are not suitable for accounting for more than 95% of assets in balance sheet because most of them want to get high profits in the short-term. Currently, major new drug development companies usually apply for loans from the Direct Guarantee Dept. of the Small & Medium Enterprise Credit Guarantee Fund of Taiwan (Taiwan SMEG) or the Promote Industrial Innovation or R&D Loan Program of Industrial Development Bureau in Taiwan, but the amount of loan is insufficient to cover the costs for the new drug development, and this method is not a general way to obtain liability side’s financing from the bank’s direct evaluation. In the international situation, the progress from development to sale of a single new drug spends about US $800 million (about NT $24 billion) on average. Despite Taiwan's R&D strategies only cover the sectional development progress or the policy of the new usage of old drugs (drug repositioning), there is still a high degree of capital requirement. However, in the present, banks and other liability side’s investors still lack the will to invest in the new drug development companies. These investors concern about several major problems, including the lengthy product development cycle, high uncertainty of the product examination and approval, the high cost of long-term clinical trials in this industry. In addition, these companies are also faced with the problem of lacking collateral, because they invest much money in new drug R&D. On the other hand, liability side’s investors, such as banks, don’t understand the complex field of new drug development companies' business models, and this situation becomes another reason for reducing the financing will. Therefore, we should establish a general evaluation method applicable to new drug development companies, to solve the problem of cognitive differences between liability side’s investors and the borrowers, and expand the funding sources of these companies. This article refers to the actual evaluation method in other countries, chooses the most suitable and well developed evaluation model --- Korea Technology Finance Corporation (KOTEC)’s evaluation method for the technology-based company, and utilizes the method to evaluate three cases of the new drug development companies in Taiwan, including Taiwan Liposome Co., Medigen Biotechnology Crop., and CytoPharm, Inc.. In conclusion of the study, by analyzing and comparing the three companies’ operating situations in recent years, we can get relative quantified scores from the companies’ overall and individual qualitative, quantitative indicators, and the result is that Taiwan Liposome Co. gets the highest score, 157 points, then Medigen Biotechnology Crop. gets the middle one. This study also refers the case situations, to find a better general business strategy for such companies. We find that new drug development company in the early stage can focus on new usage development of old drugs ,which has advantages of short development cycle and lower risk, to replace the sideline that generates short-term revenue, and accumulate the experience of drug development. When the time is ripe, it can transfer to new drug development. This way is the general suggestion of both offensive and defensive business model for new drug development companies. In addition, this study is an exploratory research, which only focuses on the evaluation stage, and has not converted the result into a corporate financing credit rating. To calculate financing credit ratings, we require a lot of historical cases data to establish a statistical analysis model, and link evaluation scores with repayment default rates. The establishment of an internal rating model or information system incurs high additional costs for the size of the banks in Taiwan, so the recommended one of the possible ways is that we can follow the example led by the South Korea Government.

A handling quality investigation was performed on the swept gull-wing configuration. The swept gull-wing configuration is tailless and has a wing with a transition in the sweep and dihedral angle. An example of this type of aircraft is the Exulans. This aircraft is currently under development at the University of Pretoria. The handling quality study was focussed on pitch axis dynamics. The Exulans is a research testbed that will be used to investigate the swept gull-wing configuration and its special controls by means of full-scale flight testing. Variable wing sweep, twisting elevons and winglets will be investigated as means of control. These control devices are configured in such a way as to have minimum impact on the performance of the aircraft. The handling qualities of the swept gull-wing configuration have to be acceptable while using these different control strategies. The study was launched to investigate whether a gull-wing configuration aircraft will have satisfactory handling qualities at CG positions associated with the most favourable aerodynamic performance. There is an aerodynamic performance gain in designing an aircraft so that the CG falls on the so-called `E-point'. The E-point is the centre of pressure for an elliptical circulation distribution. An elliptical circulation distribution is associated with the highest Oswald efficiency for an aircraft. Time domain simulation techniques and frequency domain analysis techniques were used to analyse the handling qualities of the gull-wing configuration. The C-star criterion was used to analyse handling qualities with time domain simulation data as input. Comparative time domain simulations were performed between the Exulans and other aircraft to compare handling qualities. Eigenvalue analysis was used together with the thumbprint criterion to investigate inherent gull-wing airframe dynamics. The Shomber-Gertsen and Military Specification 8785 criteria were also used for the same purpose. The Neal-Smith method was used to investigate the effect of control authority on handling qualities and the effect of a pilot. The Monnich and Dalldorff criterion was used to evaluate gust handling qualities. An analysis chart by Fremaux and Vairo was used to evaluate the tumbling susceptibility of the gull-wing configuration. The pitch handling quality investigation shows sufficient promise that the swept gull-wing configuration will have acceptable handling qualities with the CG placed at positions associated with optimised aerodynamic performance. Analysis showed that the swept gull-wing configuration is potentially prone to tumbling. With low static margins, the configuration should exhibit improved handling qualities in gusty conditions when compared to existing tailless aircraft. It is recommended that a lateral handling quality study be performed before full scale flight testing commences on the Exulans. In addition, the possibility of wingtip stall must be investigated for the case of the swept gull-wing configuration. / Dissertation (MEng)--University of Pretoria, 2008. / Mechanical and Aeronautical Engineering / unrestricted

S’appuyant sur les théories du financement hiérarchique et du compromis, cette recherche se donne pour objectif de tester empiriquement la relation structure financière-institution. Ces deux notions partagent des caractéristiques communes favorisant leur association conceptuelle à travers le ratio d’endettement cible spécifiquement via le comportement de conservatisme financier des entreprises. Cela ouvre de nouvelles possibilités d’analyses de ladite relation, notamment, en mobilisant le néo-institutionnalisme. Un échantillon de 204 entreprises françaises cotées à la bourse de Paris, ayant des données complètes entre 1999 et 2007, a servi à entreprendre le volet empirique de l’étude. Les principaux résultats indiquent que l’ensemble des déterminants traditionnels de la structure financière, à l’exception de la taille, joue un rôle important dans la politique de financement de ces entreprises. Le niveau de corruption et la liquidité du marché boursier français (variables institutionnelles juridico-financières) n’influencent pas le choix du niveau d’endettement, mais jouent plutôt un rôle significatif dans le choix de la maturité de la dette. Par ailleurs, la structure financière de ces entreprises converge lentement mais sûrement vers son niveau cible. / Based on the pecking order and trade-off theories, this research aims to test empirically the relationship between corporate capital structure and institution. Both concepts share common characteristics fostering their conceptual association through the target debt ratio specifically via corporate behavior of financial conservatism. This opens new possibilities for analysis of that relationship, in particular, by mobilizing the new institutionalism framework. A sample of 204 French companies listed on the Paris stock exchange, with complete data between 1999 and 2007, was used to undertake the empirical part of the study. The main results indicate that all the traditional determinants of capital structure, except the size, play an important role in the financing policy of these companies. The level of corruption and the French stock market liquidity (legal and financial institutional variables) do not influence the choice of debt level, but rather play a significant role in the choice of debt maturity. In addition, the financial structure of these companies converges slowly but surely toward its target level.

Le financement à court terme est le parent pauvre de la théorie financière. Pourtant, les moyennes entreprises françaises utilisent fortement ce financement. Ce travail a pour objectif d’analyser les déterminants du financement à court terme pour ces entreprises. La première partie vise à établir une revue de littérature des théories permettant d’expliquer l’utilisation du financement à court terme. La deuxième partie vient tester empiriquement ces théories sur deux échantillons, à savoir 201 entreprises familiales et 1 453 entreprises managériales. Il s’agit, d’une part, de caractériser les moyennes entreprises non cotées et d’autres part, de mettre en évidence les déterminants à l’utilisation de financement à court terme. Les principaux résultats indiquent que le financement à court terme est un outil de gestion au service de la moyenne entreprise. Il peut aussi assumer deux rôles, un compensatoire et/ou un de trésorerie passive. Par ailleurs, on met en évidence que les entreprises managériales et familiales exploitent différemment le financement à court terme. / Short-term financing is forgotten by theory of corporate finance. However, French medium-sized firms use a lot this source of funding. The objective of this thesis is to analyze the determinants of short-term financing for these firms. The first part aims to establish a literature review of theories to explain the use of short-term financing. The second part empirically checks these theories on two samples, specifically 201 family businesses and 1,453 managerial firms. On the one hand, it is a question of characterizing the unlisted medium-sized enterprises and on the other hand, highlighting the determinants of the use of short-term financing. The primary results indicate that short-term financing is a management tool for the medium-sized enterprise. It can also have two functions, one compensatory and / or one passive cash. Furthermore, it brings out that managerial and family businesses exploit short-term financing differently.

La décision de détention d’actifs liquides par les entreprises a fait l’objet de rares recherches. Pourtant,les entreprises françaises détiennent des niveaux importants de liquidités parmi leurs actifs. Ce travailvise à étudier théoriquement et empiriquement les motivations et les conséquences de la décision dedétention d’actifs liquides par les entreprises.La première partie de la thèse a pour objectif d’établir un état de l’art des théories explicatives ducomportement accumulateur de liquidités des entreprises. La deuxième partie cherche à testerempiriquement ces théories sur un échantillon de 202 entreprises françaises cotées au SBF 250. Il s’agit,d’un côté, de vérifier s’il existe un niveau optimal d’actifs liquides, de présenter les différents avantageset inconvénients de la détention de liquidités et de déterminer quels facteurs intrinsèques (financiers etorganisationnels) et macro-économiques influencent le niveau de liquidités, et d’un autre côté, d’estimerl’impact des actifs liquides sur l’investissement, la performance économique et financière ainsi que surla valeur de marché de l’entreprise. Le traitement de ces deux questions est articulé autour de l’étudedes rôles modérateurs des contraintes de financement, de la gouvernance d’entreprise et des conditionsmacroéconomiques. / The topic of corporate cash holdings has received relatively little attention from the academicresearchers. Yet, French firms hold significant cash reserves. This research aims to investigate,theoretically and empirically, the motivations and implications of the decision to hold cash.The first part of the thesis aims to provide a state of the art of the theories explaining corporate cashholding behavior. The second part seeks to empirically test these theories on a sample of 202 Frenchcompanies listed on the SBF 250. We first test the existence of an optimal level of liquid assets. Wesubsequently explore the advantages and disadvantages of holding cash before we examine the specific(financial and organizational) and macro-economic determinants of corporate cash levels. Finally, weestimate the impact of liquid assets on firms’ investment, performance and value and then we analyzethe moderating roles of financial constraints, corporate governance and macroeconomic conditions.
