Cette thèse applique la théorie des prospects et la théorie du regret à l’étude sur la performance des actions et à expliquer une anomalie du marché connue appelé l’effet momentum. Cette thèse propose un modèle théorique qui lie les facteurs comportementaux à la performance des actions et à l’effet momentum, et ensuite réalise des tests empiriques pour examiner le modèle théorique. Dans le chapitre 2, le modèle est établi sur un concept des gains/pertes potentiels, qui indiquent si un investisseur se trouve actuellement dans une situation gagnante ou perdante. Ensuite, le modèle montre que les investisseurs sont très réticents à vendre leurs stocks dans une situation des grands gains ou des grandes pertes. Les chapitres 3 et 4 effectuent des tests empiriques sur le modèle des gains/pertes potentiels. L'échantillon des tests comprend tous les stocks de NYSE et l'AMEX de l’année 1982 à 2012. Les tests sont en mesure de confirmer l'influence des gains/pertes potentiels sur les rendements des actions. En outre, une stratégie de coût nul d’Extrémité moins Moyen (EMM), basée sur le modèle théorique, est documentée pour être rentable après contrôlée pour des risques. Dans le chapitre 5, le modèle des gains/pertes potentiels est développé dans une version dynamique. Il suggère que l'influence des gains/pertes potentiels pourrait persister pendant une période de intermédiaire à long terme, et génère une tendance à la hausse de la performance pour les actions avec un grand gain/perte potentiel. Les tests empiriques dans ce chapitre se concentrent sur l'évolution de série temporelle des rendements. Les tests montrent que les actions avec un grand gain/perte potentiel ont une plus forte tendance à la hausse. Le chapitre 6 applique les résultats du chapitre précédent pour expliquer l'effet momentum. La tendance à la hausse correspond à une auto-corrélation positive des rendements, ce qui est l'une des sources qui contribuent au profit de momentum. Les tests empiriques dans ce chapitre regardent la similitude entre la stratégie de momentum et les gains/pertes potentiels, et examinent également la corrélation entre le profit de momentum et le profit de la stratégie EMM. Les tests montrent que des gains/pertes potentiels pourraient contribuer à l'effet momentum, mais ne sont pas la seule source. L'effet momentum peut être le résultat d'une combinaison de plusieurs facteurs complexes. / This dissertation applies the prospect theory and the regret theory to the study on the stock performance and to explain one well-known market anomaly called the momentum effect. The dissertation proposes a theoretical model that links the behavior factors to stock performance and the momentum effect, and performed empirical test to examine the theoretical model. In chapter 2, the model is established on the concept of the potential gain/loss, which indicates if an investor is currently at a winning or a losing position. The model then shows that the investors are highly reluctant to sell their stocks in a large gain or in a large loss situation. The chapter 3 and 4 perform empirical tests on the model of potential gain/loss. The test sample includes all stocks in NYSE and AMEX from 1982 to 2012. The tests are able to confirm the influence of the potential gain/loss on stock returns. Moreover, a zero-cost Extremity minus Middle (EMM) strategy based on the theoretical model is documented to be profitable after controlling for risks. In chapter 5, the model of potential gain/loss is developed into a dynamic version. It suggests that the influence of a potential gain/loss could persist over an intermediate to long term, and generates an upward trend in performance for stocks with large potential gain/loss. The empirical tests in this chapter focus on the time serial evolution of returns. The tests show that stocks with large potential gain/loss have a stronger upward trend. The chapter 6 applies the results from the previous chapter to explain the momentum effect. The upward trend corresponds to a positive return autocorrelation, which is one of the sources that contribute to the momentum profit. The empirical tests in this chapter look into the similarity between the momentum strategy and the potential gain/loss, and also examine the correlation between the momentum profit and the profit from the EMM strategy. Tests show that the potential gain/loss could contribute to the momentum effect, but is not the only source. The momentum effect could be a result of a combination of many complex factors.

The South African Income Tax Act (58 of 1962) does not specifically deal with the tax treatment of receipts resulting from illegal activities. Expenditure resulting from illegal activities is also only partly dealt with in terms of Section 23(o) of the Income Tax Act. This has resulted in uncertainty pertaining to the normal income tax treatment of illegal activities within a South African context. In response to this, the South African Revenue Service has issued a draft interpretation note dealing with the tax consequences of embezzlement and theft of money for both the victim as well as the offender during 2013. This draft interpretation note also deals with the normal tax consequences of illegal receipt in the hands of the thief. In an attempt to evaluate this draft interpretation note to clarify the tax consequences of illegal activities in South Africa, the meaning of illegal receipts is firstly determined. Subsequently the concept of „illegal receipts‟ is measured against the definition of „gross income‟ contained in Section 1 of the Income Tax Act. Expenditure relating to illegal activities is also analysed and measured against the general deduction formula contained in Section 11(a) of the Income Tax Act. Relevant principles established from general case law applicable to the definition of gross income as well as the general deduction formula is analysed to determine its applicability within the context of illegal receipts and expenditure. Also, principles established through case law, both nationally and internationally, specifically applicable to the taxation of illegal activities were analysed to establish guidelines that could be applied to clarify the taxability of illegal activities within a South African context. / MCom (South African and International Tax), North-West University, Potchefstroom Campus, 2015

Background and problem: The capital gain tax was introduced in Sweden as late as 1991. Previous studies has shown that capital gain tax can explain differences in investors behaviour that can lead to trading changes and a lock-in effect on the stock market, which directly affects the liquidity of stocks. The problematic is that an illiquid stockmarket, among other things, could lead to that capitals stays in already mature companies and hamper IPOs. Purpose: The study ́s purpose is to study the relationship between capital gains tax and liquidity with control of others factors that might explain differences in liquidity on the stock market. Method: The study is conducted with a quantitative method and it ́s based on data collected from 1992-2000 for companies listed on Stockholm Stock Exchange. The method generated 939 observations for each variable and the study yielded a total of 5643 observations with a final loss of 34,6 % of the study ́s sample. We formed a hypothesis to answer the research question and achieve the purpose of the study. Conclusions: The study ́s results do not reject the study hypothesis of a negative relationship between capital gains tax and liquidity, which means that liquidity falls when capital gain tax rate increase in accordance with the existing theory. A negative correlation between capital gain tax and liquidity, might hamper IPOs of new companies, because the capital stays in the already mature companies and investors are discouraged from more productive investments. / Bakgrund och problem: Kapitalskatten infördes i Sverige så sent som 1991. Tidigarestudier har visat att kapitalskatt kan förklara skillnader i investerares beteende som kange upphov till tradingförändringar och en inlåsningseffekt på aktiemarknaden vilketdirekt påverkar aktiers likviditet. Med bakgrund av denna problematik skulle en illikvidaktiemarknad bland annat kunna leda till att kapital stannar i redan mogna bolag ochförsvårar börsintroduktioner. Syfte: Studiens syfte är att studera sambandet mellan kapitalskatt och likviditet medkontroll för andra faktorer som kan tänkas förklara skillnader i likviditet påaktiemarknaden. Metod: Studien genomförs med en kvantitativ undersökningsmetod och baseras på datainsamlad från åren 1992-2000 för företag noterade på Stockholmsbörsen. Denna metodgenererade 939 observationer för studiens respektive variabel vilket gav totalt 5643observationer med ett slutgiltigt bortfall på 34,6% av studiens mätpunkter. Vi utformadeen hypotes för att besvara studiens frågeställning och uppnå syftet med studien. Slutsatser: Studiens resultat förkastar inte studiens hypotes om ett negativt sambandmellan kapitalskatt och likviditet, vilket innebär att likviditeten sjunker närkapitalskattesatsen ökar i enlighet med befintlig teori. Eftersom ett negativt sambandföreligger mellan kapitalskatt och likviditet, finns risken att en hög kapitalskattförsvårar börsintroduktion av nya bolag, att kapital stannar i redan mogna bolag samt attinvesterare avskräcks från mer produktiva investeringar.

En tant qu'accroissement de la valeur d'une chose, la plus-value est une richesse nouvelle particulièrement convoitée lorsque sa production résulte du non­propriétaire de la chose. Résoudre le conflit entre le propriétaire de la chose et l'auteur de la plus-value suppose de la situer par rapport à la chose pour pouvoir définir sa maîtrise. L'étude répond à cette problématique en menant d'abord une analyse de la présence de la plus-value. La plus-value semble dans une situation ambivalente puisqu'elle apparaît attachée à la chose tout en lui étant distincte. Cette situation ambivalente de la plus-value devait être prise en compte pour la définir à partir d'une analyse civile et fiscale. La naissance d’une plus-value a également été examinée en procédant à une relecture systématique des facteurs qui la produisent. Sur cette base, l'ouvrage propose ensuite de déterminer les modalités de maîtrise de la plus-value. La dépendance de la plus-value envers la chose implique de l'appréhender par la médiation de la chose. Cette forme de maîtrise d'une plus-value n'est pas sans générer des difficultés puisqu'elle nécessite de saisir la chose. Sans autre examen, on aperçoit immédiatement que cette solution est susceptible d'enrichir le propriétaire du bien dont la chose bénéficie d'une plus-value produite par un tiers. Cette difficulté a été dépassée à partir d'une étude du rapport entre la plus-value et la monnaie, pour ensuite envisager l'existence d'une indemnité de plus-value au profit de son auteur. / The capital gain is a new form of wealth, especially coveted when the production results from someone other than the owner of the object itself. To salve the conflict between the owner of the object and the originator of the capital gain one has to situate that capital gain in law to define its control. The study answers to this issue by firstly analyzing the presence of the capital gain. The capital gain has been identified as a distinct entity from the object, to which it is however attached. This ambivalent situation of the capital gain has to be considered when defining its consistence based on a civil and fiscal analysis. The origin of a capital gain has also been examined in proceeding with a systematic re-reading of its repository and the factors who produce it. Based on this, the following work proposes to determine the control of the capital gain. To understand the dependence of the capital gain towards the abject, you have to look at it through the mediation of the object. This form of contract of capital gain doesn't come without difficulties, since you have to grasp the object. Without other examination, we can immediately see that this solution might enrich the owner of the property, of which the abject benefits from a capital gain, produced by a third party. This difficulty was surpassed based on a study on the connection between the capital gain and monetary units. By considering the capital gain in the quantity of monetary units corresponding, it was proposed to control the capital gain in a monetary form. This particular way of control opens stimulating perspectives since it has then been indemnity of capital gain in favor of its originator.

This dissertation consists of two essays. In the first essay, I examine the source of momentum in stock returns. The reversal of momentum returns has been interpreted as evidence that momentum results from delayed overreaction to information. I examine momentum and reversals conditional on firms’ share issuance (net of repurchases) during the momentum holding period and show that (1) among losers, the momentum returns are statistically significant, but the reversals are non-existent, for both issuers and non-issuers; (2) among winners, momentum and reversals are restricted to issuers, but are non-existent among non-issuers. After further conditioning on firm size, I find that winner reversals are restricted to small, equity issuing firms. After excluding these small issuers from the sample, the remaining firms have strong momentum profits with no accompanying reversals. The evidence suggests that the return reversals are a manifestation of the poor performance of equity issuing firms. Further, while investor overreaction potentially contributes to the momentum among winners, a large fraction of firms do not earn any significant abnormal returns following initial price continuation, suggesting that underreaction, and not delayed overreaction to information, is the dominant source of momentum in stock returns. In the second essay, I examine alternative explanations of reversals in stock returns. George and Hwang (2007) find that long-term reversals in stock returns are driven by investors’ incentive to defer payment of taxes on locked-in capital gains rather than by overreaction to information. I show that return reversals are instead attributable to the negative relationship between firms’ composite share issuance and future stock returns documented in Daniel and Titman (2006). The ability of locked-in capital gains measures to forecast stock returns is largely subsumed by the composite share issuance measure. My results do not support the hypothesis that capital gains taxes drive long-term return reversals. / Ph. D.

創業天使(business angel)是一種新興的融資管道。以往創新產業利用創投事業募集創業基金，進行投資的工作。近年來創投的生態漸漸改變，除了資金挹注集中在營運中後期，創投事業也不再扮演提供管理諮詢的關鍵者角色。這時，創業天使的出現，不僅解決創業公司種子期資金不足的窘境，且積極涉入公司經營、提供產業諮詢，以增加企業的附加價值。 以往創投事業及創業公司的文獻中，僅就資本利得稅對雙方的投入影響作討論。而Elitzur and Gavious(2003)則試著加入創業天使的角色，利用三方模型衡量創業天使的加入能否對創投與創業公司間因道德危機問題產生的無效率有所改善。 本文以Elitzur and Gavious(2003)文章為基礎，加入政府的租稅政策，藉以衡量政府的介入是否對三方的投入有所助益。本文研究結果發現，只要政府課徵資本利得稅，將會使三方的投入水準減低；即使採取預算平衡的租稅政策，仍無法改變投入無效率以及創新產業收入過低的情況。因此，在現實社會中，政府不應課過重的資本利得稅，以期能使整個產業營收增加。如果採取對創投事業及創業天使資本利得補貼並搭配對投資之課稅，政府的原意乃是提高各行為參與者之資本利得，以增進效率水準；然而因課稅的過程中產生誘因降低的情況，最終反而會使三方的資本利得減少。唯有對單一參與者個別給予資本利得補貼並搭配課徵對誘因沒有影響的總額進入稅，才會使整個計畫的利得增加，達到有效率的投資水準。是故，政府的租稅政策對創業天使、創投事業及創業公司三者並不一定會達到較有效率的結果。

In the case of a natural person, conjugal community or an undivided succession domiciled in Peru which generates capital gains by transferring immovable goods, the profit generated is taxed with income tax andmay be graded as second category income –capital gain– or third category income–entrepreneurial income. From the analysis of Peruvian legislation, the author explains how the regularity in the transfer of immovable goods is configured to grade the profit made as second category income –when, over a year´s time, no more than two goods are transferred– and how, from the third transfer onward, the income will qualify as a third category income. Likewise, the author puts in evidence how the transfer of immovable goods occupied as a home is not considered as a capital gain when the seller does not generate third category income. / Tanto las personas naturales cuanto las sociedades conyugales, así como las sucesionesindivisas domiciliadas en el país y que producen ganancias de capital por la enajenación de inmuebles, generan rentas que se encuentran gravadas con el Impuesto a la Renta. Éstas califican como de segunda categoría –renta de capital–o tercera categoría –renta empresarial. A partir de la legislación vigente, el autor analiza cómo la habitualidad funciona como criterio para calificar las rentas obtenidas por enajenar inmuebles como de segunda categoría–cuando sean no más de dos enajenaciones en un mismo año– y cómo, a partir de la tercera, éstas serán calificadas como de tercera categoría. Asimismo, evidencia que no constituirá ganancia de capital la enajenación de inmuebles ocupados como casa-habitación cuando el enajenante no genere rentas de tercera categoría.

利差交易(Carry Trade)是在各種貨幣的利率水平上進行套利的交易以獲得價差收益的交易型態。而利差交易在這幾年創造出諸多研究的方向；利差交易又稱為套息交易，即借入低利率的貨幣，以購買其它高收益的投資工具，如高利率貨幣、股票、或是實物資產等，進而從中賺取其間的利率及匯率差價。諸如債券或國庫券等現貨金融工具所帶來的收益與該項投資的融資成本間的差額。 利差交易多在市場處於穩定低風險狀況下時，才能夠得到穩定的報酬率，因此如何客觀準確的評量目前市場所處的風險狀態，以獲得相對平穩又較佳的收益是主要的研究方向。本研究以如何求得利差交易裡面各項最佳且保持穩定性的參數與指標，假設利差交易可以經由衡量某些風險指標的平均值，並當風險指標低時建立利差交易部位，反之，當風險指標高時結束利差交易，甚至更積極進行反向利差交易，以求達到穩定報酬率的目標。 / Title of Thesis: Empirical Performance of Carry Trade Trading Strategy School/Graduate School: National Chengchi University Executive Master Of Business Administration, Advanced Finance Class – Risk Management and Insurance Group Graduate Student : Lee, Nai-Chun Instructor: Dr. Kang, Jung Pao Thesis Content: Carry trade bases on interest rate differences of many currency pairs to make capital gains and interest income and it creates many research topics in recent years. Carry trade borrows low yield currencies and invests other high yield targets such as high yield currencies, stocks, or real assets to get interest incomes and capital gains from foreign exchange rates. Only when a foreign exchange market is under stable and low-risk conditions, carry trade can achieve stable return rates. Therefore, how to objectively evaluate current market risk situations to get relatively stable and more returns is the main research topic of this thesis. This thesis reports how to get optimal and consistently stable parameters and indicators of carry trade. It assumes that carry trade can build positions by measuring some mean values of risk indicators when risk indicators are low. On the contrary, it ends the trade when risk indicators are high and even actively short carry trade positions to achieve stable return rates. Key words: carry trade、capital gain、exchange rate、risk indicator

Det har på senare tid uppmärksammats att svenska fastighetsbolag paketerar näringsfastigheter i svenska handelsbolag med utländska juridiska personer som delägare. Detta fenomen är ett skatteupplägg som kallas för handelsbolagslösningen. I uppsatsen utgår vi från ett typfall där delägarna i det svenska handelsbolaget är nederländska juridiska personer. Skatteupplägget inbegriper tre transaktionsled, där det första ledet innebär att ett säljande svenskt aktiebolag underprisöverlåter en näringsfastighet till det svenska handelsbolaget. Det andra ledet är att de nederländska delägarna avyttrar sina andelar i det svenska handelsbolaget samt fastigheten, det vill säga fastighetspaketet, till ett utomstående köpande aktiebolag i Sverige. Slutligen, efter köpet, likviderar det köpande aktiebolaget handelsbolaget och skiftar ut fastigheten till sig. Problematiken kring skatteupplägget handelsbolagslösningen är att det svenska aktiebolaget har tillgodoräknat sig fastighetens dolda värde, utan skattekonsekvenser, genom en förvärvad skattefri utdelning från de nederländska delägarbolagen. Det köpande aktiebolaget har samtidigt erhållit kapitalförlustavdrag i Sverige, som innebär att förlusten kan kvittas mot motsvarande kapitalvinster inom bolaget, och därmed minskas det skattemässiga underlaget. I samband med fastigheters långa avskrivningsperiod får dessa paketeringar stor ekonomisk betydelse. Frågan som uppstår är huruvida handelsbolagslösningen är lagenlig. Utifrån en rättsdogmatiskmetod behandlar vi problematiken genom en stegvis bedömning av transaktionerna. I samband med första steget i handelsbolagslösningen behandlar vi huruvida överlåtelsen av fastigheten från det säljande svenska aktiebolaget till det svenska handelsbolaget uppfyller villkoren för en kvalificerad underprisöverlåtelse. Vi finner att underprisöverlåtelsen är kvalificerad och att uttagsbeskattning således inte inträder. I det andra steget uppkommer frågan om de nederländska delägarbolagen blir skatteskyldiga i Sverige för den kapitalvinst som uppkommer på de avyttrade andelarna i det svenska handelsbolaget. Utifrån förutsättningar och resonemang i rättsfall, kommer vi fram till att det inte föreligger någon skatteskyldighet i Sverige för de nederländska delägarna. I det tredje steget och sista steget ställs vi inför frågan om det köpande svenska aktiebolaget i samband med upplösningen av det svenska handelsbolaget har rätt att dra av den kapitalförlust som uppstår på andelarna. Bedömningen sker utifrån om förlusten kan anses vara verklig eller inte. Med stöd av praxis anser vi att kapitalförlusten är verklig och därmed avdragsgill. I vår rättsutredning av de tre olika transaktionsleden, finner vi att dessa följer gällande rätt. Med beaktande av detta anser vi det vara av vikt att undersöka huruvida skatteflyktslagen kan tillämpas på typfallet. Med stöd av gällande rätt bör skatteflyktslagen inte bli tillämplig på det köpande svenska aktiebolagets taxering. Vi klargör istället om skatteflyktslagen kan angripa det säljande svenska aktiebolaget. I vår utredning finner vi att skatteflyktslagen inte är tillämplig på handelsbolagslösningen så som den artar sig i typfallet. Detta med stöd av vår gjorda rättsutredning samt de spekulationer som finns på området. Vår slutsats är att det blir svårt att angripa de fastighetsbolag som har utnyttjat handelsbolagslösningen, åtminstone utifrån den konstruktion som föreligger i typfallet. Utifall det är lagstiftarens intention att förhindra denna typ av skatteupplägg, är det upp till denne att komma med ny lagstiftning som tar fasta på problematiken. / Swedish real estate companies have attracted a lot of attention by packaging industrial real estate in general partnership companies that are owned by foreign legal entities. This tax arrangement is a phenomenon that is referred to as the general partnership solution. In this thesis, we use a case example in which the partners in the Swedish general partnership are legal entities with Dutch nationality. The tax arrangement includes three transaction phases, where the first involves an under priced transfer of a commercial real estate from the selling Swedish private limited company to the Swedish general partnership. In the second phase, the Dutch partners trade their shares in the Swedish general partnership including the real estate to an external buying private limited company in Sweden. After the trade the buying Swedish private limited company liquidates the general partnership and transfer the real estate from the general partnership to itself. As a result of this tax arrangement a complex problematic arises when the Swedish private limited company obtain the hidden value in the real estate by receiving tax-free dividends from the Dutch partner companies. The buying Swedish private limited company simultaneously receive capital deficit tax deductions in Sweden, which means that losses can be settled by corresponding capital profits within the company, consequently reducing their tax base. The long depreciation period of real estates means that packaging represents great economical significance. The question that arises is whether the general partnership solution is consistent with Swedish law. Based on a juridical dogmatic method, we consider this complex of problems by means of a systematic assessment of the discussed transactions. In the first step of the general partnership solution, we consider whether the transfer of real estate from the selling Swedish private limited company fulfils the conditions for a qualified under priced transfer. We find that the under priced transfer is qualified, and therefore withdrawal taxation does not occur. In the second step, the arising question is whether the Dutch partner companies become liable for taxation in Sweden for capital profit generated from the disposed shares in the Swedish general partnership. According to the prerequisites and reasoning in legal cases, we find that tax liability in Sweden does not arise for the Dutch partners. In the third and final step, we are faced with the question whether the buying Swedish private limited company has the legal right to deduct the capital loss that results from the Swedish general partnership resolution. The assessment is based on whether the loss can be considered genuine. In accordance with case law we regard the capital loss genuine and therefore tax-deductible. In our legal inquiry we conclude that the three different transaction phases comply with Swedish law. Considering this, we find it imperative to examine whether the Swedish tax evasion law can apply in the case example. By virtue of domestic law, it is not probable that the tax evasion law can apply on the buying Swedish private limited company’s taxation. In regards to the seller’s taxation, we clarify whether the tax evasion law can be applicable concerning the selling Swedish private limited company. We find that the tax evasion law is not applicable in the general partnership solution, in the form that it has in the case example. We support this statement with reference to our legal inquiry and referring to some speculations on the subject. Our conclusion is that it would be difficult to deal with the real estate companies that have made use of the general partnership solution, at least in the construction that exists in the case example. It is up to the legislator to decide on whether to prevent this type of tax arrangement or not.
