Tomaník, Jan. "Nestandardizované opční kontrakty - warranty." Master's thesis, Vysoká škola ekonomická v Praze, 2009. http://www.nusl.cz/ntk/nusl-76436.
Full textAbstract:
The thesis is mapping current situation on the market in warrants as nonstandardised option contracts. Particular attention is paid to the special issues of warrants modified into the form of so called "access products". The function of such financial instrument is to open extraordinary investment opportunity to certain kind of investors, who otherwise are not allowed to make direct investment into the underlying asset itself. Access products can be considered as particular financial innovation, which spread out on Central European capital markets. The most familiar form of access products are low strike price covered call warrants, the characteristics of which are being analyzed and compared to standard options and warrants. The author also focuses on the process of issuing warrant securities on Czech capital market according to Czech law and problems linked to it, which the issuer encounters. The thesis proves on the example of Fondul Proprietatea Warrants, which were in 2010 successfully placed to third market of Vienna Stock Exchange by Czech entity, that such warrant issue is possible despite of material complications stemming from the absence of clear definition of warrants in Czech law.

Full textAbstract:
Från mitten av nittiotalet fram till början av tjugohundratalet har riksbanksräntan haft en sjunkande trend vilket har medfört att många av de svenska småspararna har sökt sig till andra investeringsmöjligheter än enbart bankkonton. Warranter har här varit ett billigt men riskfyllt alternativ på börsen. En warrant är väldigt lik en option, med den skillnaden att en market maker (anställd av emittenten) används för att kontinuerligt ställa köp och säljkurser för en warrant. Detta innebär att prissättningen sker subjektivt, vilket leder oss till vår problemformulering som lyder:
Är det möjligt att urskilja olika prissättningsstrategier hos emittenterna när det gäller den implicita volatiliteten?
Med tanke på detta problem har vi valt att utgå från en kvantitativ studie och valt att se det från småspararnas perspektiv. Vårt huvudsyfte är att se om vi kan urskilja om emittenterna på den svenska marknaden har olika prissättningsstrategier när det gäller den implicita volatiliteten på warranter. Vår teori utgår från en beskrivande del för att förklara hur en warrant fungerar samt en sammanfattning av den forskning som finns på området.
Vi utgår från en positivistisk kunskapssyn där vi strävar efter att finna en förklaring till ett eventuellt samband mellan emittenternas prissättningsstrategi och den implicita volatiliteten. Vår ansatts för att närma oss vårt problem är hypotetiskt-deduktivt och vi har använt oss av alternativhypotesen:
H1: Alla emittenter har olika implicit volatilitet.
Vi har samlat in våra data dagligen i drygt två månader via Derivatinfo. Dessa har vi sedan valt att bearbeta i SPSS. De resultat som genererats har vi valt att presentera i form av diagram och tabeller. Dessa tyder på att emittenterna har olika prissättningsstrategier, dock kan vi inte säkerställa detta.

Full textAbstract:
Byggföretagen lägger ner åtskilliga timmar på icke inkomstbringande arbete årligen tillföljd av garantihantering. Det är tid som med fördel kan användas i pågående produktionen istället. Det kostar entreprenörerna och kunderna tillsammans 1,3 MDR kr per år för garantihanteringen (Boverket 2007), vilket enbart är med hänsyn till tid nedlagd av byggföretagen och kunderna för att åtgärda felen. Med denna bakgrund kommer följande studie undersöka möjligheterna för ett externt förvaltningsbolag att ta över garantihanteringen, för att Företaget skall kunna lägga all sin tid på den producerande verksamheten. En kartläggning över hur hanteringen fungerar idag på ett entreprenörsföretag med avseende att besvara frågeställningen Hur påverkar det Företaget utifrån tidsåtgång, kostnader och kundnöjdhet om ett förvaltningsbolag tar över hanteringen av garantiåtgärder? Slutsatsen från studien visar på att Företaget skulle dra fördelar av att använda sig av ett externt förvaltningsbolag som ansvarar för garantihanteringen. Detta skulle leda till kortare handläggningstider vilket kan leda till ökad kundnöjdhet. Företaget skulle dra fördelar av att pågående produktion inte skulle belastas av garantiåtagande i samband med outsourcing. P.g.a. Företagets bristfälliga tids- och kostnadsredovisning gällande garantihanteringen, går det inte att dra några slutsatser om det skulle vara lönsamt för Företaget ur ett kostnadsperspektiv.

Fredriksson, Joel, and Andreas Kristoffersson. "Moderna hävstångsinstrument : En studie av Mini Futures framtid på den svenska marknaden." Thesis, Linnéuniversitetet, Ekonomihögskolan, ELNU, 2011. http://urn.kb.se/resolve?urn=urn:nbn:se:lnu:diva-18976.
Full textAbstract:
Det har skett en nästintill explosionsartad utveckling på den svenska marknaden för hävstångsinstrument under de senaste åren och en mängd nya produktinnovationer och emittenter har dykt upp. Handeln med Mini Futures är väl utbredd i Europa där det funnits under en längre tid, och produkten lanserades för några år sedan på den svenska marknaden. Syftet med denna uppsats är att kartlägga både emittenter och konsumenters syn på Mini Futures och analysera om dessa hävstångsinstrument är lämpliga för vanliga småsparare. Likaså vill vi undersöka produktens potential och hur framtidsutsikterna kan se ut på den svenska marknaden. Vi har genomfört en kvalitativ studie där vi intervjuat personer som arbetar med eller i nära anknytning till handeln med hävstångsinstrument. Studien har även kompletterats med en kvantitativ enkätundersökning för att lyfta in investerarnas perspektiv. Respondenterna bestod av medlemmar i Unga Aktiesparare som vi anser de intresse som krävs för att kunna ge trovärdiga svar. Då Mini Futures är en relativt ny produkt är forskningen inom området högst begränsad. Vi har därför byggt upp vår teoretiska referensram med teorier som påverkar börshandeln i allmänhet, bland annat börspsykologi, risker och portföljteori. För att kunna förstå moderna investerarbeteenden har vi också tagit med en del forskning om generation Y. I vår analys har vi vävt ihop våra informanters röster med resultaten från vår enkätundersökning samt sökt stöd i den teoretiska referensramen. Detta har sedan analyserats utifrån valda områden: Risk och möjlighet, Hävstång i portföljen, Kunskap och marknadsföring, Förutsättningar för emittenternas val samt Framtid och utveckling. I de slutsatser som presenteras i uppsatsen berör vi bland annat hur sparandet i Mini Futures bör förhålla sig till traditionellt sparande, för vilka personer som det inte är lämpligt att handla med Mini Futures, i vilket syfte produkten kan användas samt hur utvecklingen kommer se ut på den svenska marknaden. Avslutningsvis ger vi rekommendationer på framtida forskning inom området.There has been a boom on the Swedish market for leveraged products and a whole new set of product innovations and issuers have emerged. Trading in Mini Futures is widely spread in Europe and the product was launched on the Swedish market a few years ago. The purpose of this paper is to identify both issuers and consumers' views on Mini Futures and analyze if these leveraged products are suitable for small time investors. Also, we want to explore the potential of the product and what future prospects look like on the Swedish market. We conducted a qualitative study where we interviewed people who work in close association with, and have a vast knowledge of, leveraged instruments. In order to raise the investor’s perspective we have also supplemented this study with a quantitative survey. The respondents consisted of members from the Young Shareholders Association which we consider have a good awareness of the market. Mini Futures is a relatively new product and research in this field is very limited. Therefore we had to build our theoretical framework with theories that affect the stock market in general. For example stock market psychology, risk and portfolio theory. In order to understand modern investor behavior, we also included some research on Generation Y. In the analysis, we combine the empirical research results with the results of the survey and sought support from the theoretical framework. This was then analyzed from selected areas Risk and opportunity, Leverage in the portfolio, Knowledge and marketing, Conditions for the issuers´s choice, Future options and development. The conclusions presented in this paper concerns how the savings in Mini Futures should relate to traditional savings, which individuals are not appropriate to trade with Mini Futures, for which purposes the product can be used and how the future development will look like on the Swedish market. Finally, we give recommendations for future research in the area.

Full textAbstract:
Os estudos sobre a diversidade cultural na Organização do Conhecimento estão imbricados na temática do local/global. Em uma sociedade da informação globalizada, aspectos culturais e éticos adquirem grande relevância nas discussões sobre as implicações da utilização de sistemas de organização do conhecimento em escala global/local. Enquanto produtos culturais, os sistemas de organização do conhecimento expressam valores, que podem ser analisados do ponto de vista das garantias sobre as quais tais sistemas se constituem. As garantias estão sempre presentes em sistemas de organização o conhecimento, embora nem sempre sejam aplicadas de modo consciente e sistemático, ou mesmo apresentadas de modo transparente para os usuários dos sistemas. Desse modo, o objetivo desta pesquisa é analisar o conceito de garantias como ferramenta teórico-metodológica que, em suas diversas formas, pode contribuir para a incorporação da diversidade cultural às práticas da Organização do Conhecimento. Parte da hipótese de que formas de garantias estão sendo desenvolvidas e/ou reformuladas para permitir a elaboração de sistemas organização do conhecimento que incorporem a diversidade cultural como valor ético. Discute os conceitos de cultura, diversidade cultural, globalização e sociedade da informação como elementos-chave em estudos voltados para as dimensões cultural e ética da Organização do Conhecimento. Discute os pressupostos teóricos dos conceitos de garantia, garantia literária, garantia cultural e garantia ética. Identifica demais formas de garantias propostas na literatura da área para verificar o contexto de uso das garantias, a precisão conceitual dos termos e identificar suas possíveis inter-relações por meio da análise de artigos publicados em periódicos acadêmicos e da construção de um glossário com os termos identificados. Verifica que as discussões de conceitos já estabelecidos, como os de garantia cultural e garantia do usuário, e a formulação de outras garantias, tais como a garantia autopoiética ou a garantia do ponto de vista podem ser relacionadas à incorporação da diversidade cultural às práticas da Organização do Conhecimento.Research about cultural diversity in Knowledge Organization is connected to the theme local/global. In a globalized information society, cultural and ethical aspects come to the fore in discussions about the implications of using knowledge organization systems in a global/local scale. As cultural products, knowledge organization systems embody values which can be analyzed from the standpoint of the warrants on which they are based. Warrants are always present in knowledge organization systems, even though they are not always applied consistently and systematically, or even made transparent to the users of such systems. Thus, the objective of this research is to analyze the concept of warrants as a theoretical and methodological tool which, in its various forms, may contribute to the integration of cultural diversity to knowledge organization practice. The research is based on the hypothesis that forms of warrant are being developed and/or reconceptualized to allow for the design of knowledge organization systems in which cultural diversity is integrated as an ethical value. It discusses the concepts of culture, cultural diversity, globalization and information society as key elements in research about the ethical and cultural dimensions of Knowledge Organization. It discusses the theoretical framework of the concepts of warrant, literary warrant, cultural warrant and ethical warrant. It identifies other forms of warrant in the literature to analyze their context of use, their conceptual accuracy and potential inter-relations through a survey of the terms in conceptual papers to write a glossary. It was noted that research about more established concepts, such as cultural warrant and user warrant, and the development of other warrants, such as autopoietic warrant or viewpoint warrant are related to the integration of cultural diversity in knowledge organization practice.

Credit is an asset of the creditor that can be transferred, allowing event the constitutionof a security on it.

Is this right?In this article, the author develops the answer to this question, through a systematic interpretation of Peruvian legislation and the credit figure as an object of movable collateral.El crédito es un activo del acreedor que puede ser transferido, permitiéndose, incluso, que se constituya garantía sobre el mismo.

Barton, Jon. "Warrant and objectivity." Thesis, King's College London (University of London), 2007. http://sas-space.sas.ac.uk/1082/.
Full textAbstract:
Wright's 'Truth and Objectivity' seeks to systematise a variety of anti-realist positions. I argue that many objections to the system are avoided by transposing its talk of truth into talk of warrant. However, a problem remains about debates involving 'direction-of-fit'. Dummett introduced 'anti-realism’ as a philosophical view informed by mathematical intuitionism. Subsequently, the term has been associated with many debates, ancient and modern. 'Truth and Objectivity' proposes that truth admits of different characteristics; these various debates then concern which characteristics truth has, in a given area. This pluralism of truth is at odds with deflationism. I find fault with Wright's argument against deflationism. However, transmission of warrant across the Disquotational Schema suffices to ground Wright's proposal, which survives as a pluralism of classes of warrant. The two main debates concern whether truths are always knowable (Epistemic Constraint) and whether disagreements in an area must be down to some fault of one of those involved (Cognitive Command). I introduce Assertoric Constraint, relating to Epistemic Constraint, where truths cannot outstrip the availability of warrant for their assertion. I solve a structural problem by a comparison with a constitutive analysis of Moore's Paradox. The relativism of blameless disagreement is problematic. Wright's response invokes a sort of ignorance which he calls 'Quandary'. I criticise this before proposing an alternative. I agree with Wright that Dummett's original anti-realism does not belong among the positions which Wright seeks to systematise. However, two candidates show that the proposal suffers a weakness. Wright thinks Expressivism misguided, and implicitly rules out his earlier non-cognitivism about necessity. I argue that Expressivism has promise, and I endorse Wright’s Cautious Man argument for non-cognitivism about necessity; both involve play with 'direction-of-fit'. I conclude that this sort of anti-realist debate needs to be accommodated by the proposal.

Mapping the world market derivatives, and then describes the basic characteristics of the main types of contracts. After the general characteristics of the derivatives in the introduction, are briefly described two types (forwads and swaps) that are not directly used in the family finances. In their description, however, are pointed out the fundamental principles of derivatives and trading with them. In the next section, the focus is on those derivatives that are suitable for use in household budgets. They include Futures, Options, Warrants, Investment Certificates, Exchange Traded Funds (ETF), Contracts for diference (CFD). There are also discussed basic principles of these instruments, their use and the current bid.

Full textAbstract:
With the current fiscal constrains placed on the Army to help combat the national debt, the acquisition community must find cost savings avenues without sacrificing mission readiness. During the acquisition process in the DoD, extended warranties are often made available by a supplier, a third party, or through self-insurance. The cost impact of extended warranties can be significant. Furthermore, the ability to service and maintain equipment, either at sea or on land, has a critical impact on the Armys and the DoDs mission capability. I will do a review of warranty planning system in the Army and provide a case study on the purchase of 55 Hewlett Packard Laser Printers in Afghanistan to illustrate the potential cost savings by electing to use extended warranties based on a formal model and simulations in order to bridge the gap between the academic literature and the professional experiences of the service members in order to help solve the difficult task of determining the terms of extended warranty contracts and its value to the Army. While warranty planning is not required, it can potentially save the Army millions of dollars in day to day commercial products acquisitions. The result of the model and simulation show that by making a large upfront purchase of an extended for 3 years versus the free standard warranty of one year, the unit can save on average 11.16%. Due to the budget constraints, Contracting Officers with the assistance of everyone in the acquisition process should emphasis extended warranty purchase in commercial products to reduce risk and lengthen the life-cycle replacement cost to the government. The Army has a regulation emplace for the warranty management program in AR 700139, but I believe more guidance is needed from the Armys key leadership in order to fully realize the cost savings from extended warranties.

Warrant, in classification, is encompassed in the Oxford English DictionaryiÌ s definition: "justifying reason or ground for an action, belief, or feeling." Classifications may be deemed good or bad on the basis of any number of characteristics, but the justification for their choice and order of classes or concepts is one of the most fundamental. This paper will introduce the notion of warrant used by Francis Bacon in his classification of knowledge, discuss its uniqueness within the panoply of classificatory history, and suggest that Bacon still has a radical idea to suggest to todayiÌ s classificationists.

Full textAbstract:
Due to the sharpen regulation of the Swedish plain vanilla warrant in 2006 and the recent increase in trade among private investors, this thesis examined the informa-tion efficiency of Swedish plain vanilla warrants. This was done in three different ways. First the theoretical Black & Scholes (B&S) price was tested against the ac-tual market price. Secondly likelihood ratio test statistics was used to see whether information regarding past returns added any information to that already captured by the implied volatility (IV) generated from observed warrant market prices via the B&S model. The third method used was a comparison of the IV´s among com-parable warrants. As the regulation of the Swedish plain vanilla warrant market states that only certified issuer are allowed short calls and puts, the self adjusting price mechanism found in the option market doesn’t exist on this market. As a con-sequence of this, investors on this market is reliant of accurate ask and bid prices from the issuers. Further, the information efficiency of a capital market is of es-sence for capital allocation, price discovery and risk management. The results from all three tests rejected the information efficiency hypothesis of the sample. Thus concluding that the included warrants in this thesis are none ideally for activities such as capital allocation, price discovery and risk management.

Full textAbstract:
Warranty is a contract between a seller and a buyer. A warranty is also a signal for quality that can be utilized both by the seller and the customer. Even though the warranty is mainly something that is positive, a warranty also incurs risk to the warranty provider. The warranty cost can range from 2 - 15% of the net sales of a product which means that the warranty cost could potentially affect the company a lot. In order to handle such a risk, forecasting is a necessary tool. Forecasting is no exact science, and it’s impossible to forecast the exact future value due to uncertainty. Factors such as the quality of the product affect the cost of the claims, but unpredictable factors such as fraud, human factors and sales delay must also be considered. Forecasting error affects the warranty provider because the forecast sets the warranty reserve, which should cover the costs of the warranty claims. Overestimations and underestimations of the reserve have negative consequences for the company. The purpose of this study is to forecast a warranty reserve using a quantitative approach, in order to gain insight in to which model that could be best suited for complex products. The models that have been tested originate from causal and time-series methods, where the models tested consider different aspects of the data. The primary data used comes from archive data and to determine the forecast error, error measurements have been utilized. The time series method exponential smoothing Holt’s- Winter’s method was the one that performed best considering the error measurements. From the models tested, it has been shown that a more complex model does not necessarily mean a more accurate result. To be able to decrease the forecasting errors, a model considering unpredictable factors such as fraud could be the answer which makes it interesting to investigate.Garanti är ett kontrakt mellan en säljare och en köpare. En garanti används ocks. för att signalera kvalitet vilket kan vara användbart för både säljaren och kunden. Även då garanti främst är något positivt innebär garanti ockå. en risk för den som erbjuder garantier då kostanden att erbjuda garanti kan sträcka sig mellan 2–15% av nettoresultatet av försäljningen va en produkt vilket betyder att garanti kan påverka företaget mycket. Man anv.nder sig av prognostiseringar för att kunna hantera den risken garantin bär med sig. Prognostisering är svårt och det är omöjligt att prognostisera det exakta framtida värdet på grund utav osäkerhet. Faktorer så som kvaliteten av produkten påverkar antalet och kostnaderna på garantianspr.ken men oförutsägbara faktorer så som bedrägeri, mänskliga beteenden och fördröjning av försäljning av produkter måste också tas i akt. Prognostiseringsfel på verkar den part som erbjuder garantin då prognosen används för att lägga undan monetära medel till garantireserven för att täcka garantianspråk. Underestimat och överestimat har negativa konsekvenser för företaget. Ändamålet med denna studie är att prognostisera garantireserven med hjälp av kvantitativa metoder för att få en inblick i vilka modeller som fungerar bra för en komplex produkt. Modeller som har testat kommer fr.n tidsserie metoder och kausala metoder, då de olika metoderna tar hänsyn till olika aspekter i data. Primärdata som används kommer från arkivdata och för att kunna bestämma felen på de prognoser som gjorts används fel mått. Tidsserie metoden exponential smoothing Holt’s-Winter’s var den som gav bäst resultat på fel måtten. Resultatet av modellerna som testats visar på att en mer komplex modell inte behöver vara den som ger bäst resultat. För att kunna minska på prognostiseringsfelen kan en modell som tar hänsyn till oförutsägbara faktorer så som bedrägeri vara lösningen vilket är en intressant sak att undersöka.

Full textAbstract:
It has been pointed out by numerous authorities that the legality issue is one of the most complex and difficult areas in English law. Countless rules and principles have been created by former authorities, on one hand, principles which have been created by common law give guidance to the English courts when deal with this issue, on the other hand, however, these judgments make this area far from clear an stable. However, compared with one more special area, the legality issue in marine insurance law, the instability of rules in English common law makes itself useful instrument. Section 41 of Marine Insurance Act 1906, which is known as warranty of legality, requires the adventure is a lawful and so far as the assured can control the matter, the adventure shall be carried out in a lawful manner. However, this piece of law has imposed a rigid and unfair system on the assured. According to former authorities, it can be seen that, the illegality rules in marine insurance law is far more complex than section 41; and, moreover, English common law also provide useful instruments for marine insurance law. This thesis begins with the analysis of section 41 in marine insurance law and tries to explore the true scope of section 41 in marine insurance. And then the principles of legality issue in English common law will be introduced in detail; furthermore, the pattern of resolve legality issue in Australia and New Zealand will be introduced as well, since the common grounds these three legal systems share. And based on the introduction of the reform which have been taken by Australia and New Zealand, this thesis will try to explore the positive methods which can be absorb by English law as well. And in the end, the new reform of English law on the legality issue in insurance and marine insurance law which has been proposed by the Insurance Contract Law Bill 2014 will be analysed as well, and based on former analysis, this thesis will propose a practical method to reform this issue in English law, that is to apply the common law rules in marine insurance law.

Full textAbstract:
As a special contractual term, warranties in marine insurance policy are crucial for risk assessment purpose. Warranty in marine insurance law has survived for centuries. Despite its long period of existence, the current warranty regime has been criticised by a number of scholars and the Law Commission. The main criticism is that it operates unfairly against the assured. Due to the existing problem of the current warranty regime, the main aim of this research is to critically analyse the law of warranty in the English Marine Insurance Act 1906. Where necessary, some law reform proposals will be introduced into the Marine Insurance Act 1906. Moreover, a critical comparison between the law of warranty in the Chinese Maritime Code 1993 and the law of warranty in the Marine Insurance Act 1906 will be made. Due to the simple provisions of Article 235 of the Maritime Code which deals with the issue of warranty, some new law proposals will be introduced into this Article for clarification purpose. In order to achieve these merits, this thesis concentrates on the critical examination as to the law of warranty under the relevant provisions of the Marine Insurance Act 1906 and the Maritime Code 1993. Some law reform proposals made by other scholars will be critically analysed. In particular, the historical development of English and Chinese marine insurance will be provided in Chapter 1 and 3 respectively. The research on the issue of warranty consists of 4 Chapters, namely Chapter 2, Chapter 4, Chapter 5 and Chapter 6. Chapter 2 provides the nature of warranty under section 33 and 34 of the Marine Insurance Act 1906 and some relevant law reform proposals. Chapter 4 consists of the discussion as to the statutory rules of warranty under Article 235 of the Maritime Code. Chapter 5 specifies the statutory rules for the creation of express warranty. Chapter 6 deals with the critical review as to the different types of implied warranty in section 39 and 41 of the Marine Insurance Act 1906, and the author will also introduce some new statutory rules as to the implied warranties to replace the present law. Additionally, as there is no implied warranty under the Maritime Code, in this Chapter, the statutory rules as to implied warranties will be introduced and inserted into the Maritime Code. Finally, Chapter 7 provides the general conclusion of this thesis for the law of warranty in England and China.

Full textAbstract:
An extended warranty provides consumers the opportunity to rectify product failures at little or no cost after the expiry of the base warranty. Empirical evidence has shown that the selling of extended warranty contract (EWC) has become a profitable business in many manufacturing and retail industries. This thesis investigates the dynamic pricing problem for a new product with the option of purchasing an extended warranty contract (EWC). The research simultaneously determines the pricing strategies for both the product and the associated EWC, and the production rate to maximize the manufacturer’s long-term total profit. The results show that the provision of EWC will significantly affect the optimal pricing strategy for the new product, and may also affect its optimal production plan.
The research establishes three mathematical models for making optimal pricing decisions under different operational settings. The first model considers a centralized selling system in which the manufacturer sells the product and offers the associated EWC to the consumer directly. The second model extends the first one by incorporating the production and inventory decisions in the analysis. The third model considers a decentralized system in which the manufacturer sells the new product to consumers through an independent retailer. The EWC can be offered either by the manufacturer or by the retailer. It is shown that each scenario leads to a differential Stackelberg game in which the manufacturer and the retailer are players.
For the first model, the Pontryagin maximum principle is used to derive the necessary condition for the optimal pricing strategies for both the new product and the associated EWC. Some properties for pricing the new product optimally are then studied. Apart from analysing the characteristics of the optimal pricing strategy under general demand conditions, closed-form solutions for the problem are also derived for some specific demand functions. In cases where closed-form solutions cannot be found, a gradient algorithm is applied to solve the problem numerically. In the second model, the production rate becomes a decision variable because the unit production cost depends on the chosen production rate. Results of the analysis show that the optimal selling price for the EWC remains the same as that in the first model, while the optimal selling price for the new product are affected by the production rate. The results also show that the gradient algorithm fails to converge, thus is no longer suitable for the second model due to the complexity caused by the boundary conditions. A more robust control vector parameterization method is then developed to compute the numerical solution. Analysing the third model theoretically indicates that some necessary conditions related to the optimal wholesale price and the optimal retail price must be satisfied for the existence of an open-loop Stackelberg equilibrium. Some important managerial insights are derived on the basis of the properties characterizing the optimal solution. The control vector parameterization method is then further developed to solve the differential game problem. Numerical experiments are then carried out to demonstrate which distribution channel results in the largest profit.published_or_final_version

This paper explores the reasons for the mispricing of warrant traded in Taiwan market. The data period is from 2010 to 2016, and we use Taiwan exchange stock index as the underlying stock. We found mispricing phenomenon is consistent with the theory of arbitrage (Shleifer and Vishny, 1997) and the theory of asset float (Hong.Scheinkman and Xiong, 2006), so we use liquidity and turnover in this study as the control of independent variables. Li and Zhang (2011) explain that the difference between the price of warrants and options in Hong Kong is based on the difference in liquidity. The data of paper uses Taiwan stock exchange index warrants and options. We found that the mispricing is partly due to the short sales constraint of warrants. Since difference in opinion and short sales constraint can make warrants prices higher than the fundamental price, the level of mispricing increases in volatility and warrants maturity. This study observes the effect of implied volatility, trading volume, maturity and the closing price of warrants with mispricing. The implied volatility is negatively correlated with the mispricing, increase which shows that when the difference in option of the investors make the price derivate. The time to maturity and the closing price are also positively correlated with the mispricing. We also found that the closing price was negatively correlated with the mispricing when the time to maturity of the put warrants are one to three months, and time to maturity is negative correlation with mispricing in more than five months. When the trading volume is high, the price can react quickly on the price of warrants, reduced the mispricing, and the results of this study found that the warrants trading volume was negatively correlated with this expectation.

This research focus on the devalue facts of warrants, and try to explain that in a new prospects of interaction mechanism between warrant and stock markets. In order to describe such mechanism, we have modified the partial difference function of Black and Scholes (1973). Finite difference method was used to simulate the new models, and compare the difference with traditional model. We found that the simulation results of nine samples from warrant market can support the prospects of interaction effects. New model can explain the pricing error facts. But it depend on stock price is in-the-money, at-the-money or out-the-money. We found that stock price was out-the-money, or it changed to at-the-money, new model performed better that traditional model. But stock price changed to in-the-money, the performance is weaker. By the way, discrete replication problem was matter. But after excluding the discrete replication effects, interaction mechanism still can explain the facts. If we discuss different interaction mechanism, such as price interaction mechanism and volatility interaction mechanism, we will have the same result. To explain that, all the interaction effects have modified volatility by the Gamma value. Gamma value is higher in at-the-money situation. That is why stock price is at-the-money, modified model can explain better than traditional model.

Compare with stocks, this study is of the opinion that there are at least three advantages of adopting Exchange Traded Funds (ETF). First of all, popular ETF is nearly non-mobility problems. Therefore, it can reduce frictional costs substantially. Secondly, the price volatility of ETF is much lower than individual stocks’ due to the reason that specific stock market index of ETF is a stock portfolio, and in consequence the price-limit circumstance is rarely found. Lastly, the trading fee could be saved due to the taxation ratio of selling ETF is lower than stocks’. In the previous studies, we had deduced to the theory ETF alternative hedging strategies, and used empirical studies in Taiwan 50 ETF. This study brings up an innovative idea of substituting Exchange Traded Funds (ETF) for underlying stocks. It based on the relativities of price changing of warrants respectively with underlying stocks and ETF, and develops a substitute model of hedging strategy model. Also, this study compares this two models’ transaction costs to hedging stock’s to find out which one is much better. In this study, Taiwan 50 ETF will be taken as a substitute hedging stock; additionally, there are 300 samples, which are randomly selected from five securities firms for warrants. In order to come up with the number of positions that each warrants holds, OLS and β coefficient of GARCH estimated model will be used in analytic process. And we also chose the top five securities firms to compare the efficiency and to find out which model is much better. And we know the ETF trading site in the same day may offset each other, so we can know the benefit, which is offset and which is not offset has the better benefit.

ABSTRACT If the call warrant writers in Taiwan hedging by the same stock of warrants of another call warrant writers, we tried to construction an option pricing model with securities transaction tax, by Hayne E. Leland presented in 1985. We showed that the securities transaction tax of call warrant and the call warrants price is the same change. At the same time, the empirical study and the revised model with securities transaction tax have same conclusion.

In a competitive market environment, the main strategic decision for a seller is determining a price schedule with respect to a specific marketing feature of the product. This paper investigates how a monopolistic seller can optimally determine the price schedule for a product with different warranty plans. By incorporating buyers' heterogeneous preferences on product warranty length, the pricing problem of a product for the seller is mathematically formulated. Four different pricing scenarios of warranted products under varies optimization objective are developed to specify the pricing problems for the seller. In each scenario, the optimal price schedule is derived such that the optimization objective is maximized by employing an optimal control approach. Finally, a numerical example is provided to illustrate the features of the proposed problem in each scenario and the sensitivity analyses of the parameters on the optimal solutions are also performed.

The Taiwan warrant market began in 1997, it has been 19 years. According to a January, 2015 market statistical data, Taiwan warrant market are second largest in Asian, sixth largest in global. For Taiwan warrant market research is also booming. Many research indicated that warrant market price is significantly different from theoretical price. However, there is limited explanation for the difference. This study sample is from TEJ data base of derivative financial products including 2013-2015 Taiwan index warrants, Taiwan top 50 index constituent stock warrants. This study firstly focuses on is warrant price fairly priced. The result shows that warrant price is not fairly priced. Second, this paper studies on the warrant price premium of Taiwan top 50 index constituent stock warrants and use regression to further explore the causes of premium. Through this study can be used as reference for investment.

In this paper we present a signaling ,based on ideas of Esther G al-Or ,in which both the price and the level of warranties are ch oice variables and the warranties be used as signals for the init ially unobservable durability of the goods .We demonstrate throug h an example that in oligapolistic model ,it is only in special c ase that warranties can serve as signal of quality .The provisio n of warranties can serve as a signal of durability only in cases in which the intrinsic attributes of products are widely enough and the period the consumers make their buying decision are not t oo long .If the intrinsic attributes of producta are too clustere d ,the provision of warranties can not serve as a signal of durab ility .When the intrinsic attribtes of products are very far apar t ,whether the provision of warranties can serve as a signal of d urability or not depend on the period the consumers make their b uying decision .If the period are not too long ,the provision of warranties can serve as a signal of durability ,otherwise ,the pr ovision of warranties can not serve as a signal of durability .We also demonstrate that when the provision of warranties can not s erve as a signal of durability and the period the consumers make their buying decision are not too long ,the provision of warranti es will not causes the signal cost.

Due to the rising competition of the market today, consumers require not only getting high quality products, but also emphasizing the content of product warranty. Having the warranty, consumers can claim for refund or repair when the product fails within warranty period. However, offering a product warranty results in additional cost to the manufacturer. Therefore, it is important to take product reliability, price, profit, and execution of warranty claims into account for accurately estimating the total warranty cost in order to determine a warranty policy. However, previous studies usually assume that consumers will fully execute the warranty claims when the product fails within the warranty period. This assumption is not reasonable in practice and it causes an over-estimation of the warranty cost. In this thesis, various warranty cost models are established under different warranty execution functions for the full-refund warranty and free-minimal-repair warranty. Numerical examples are also given to compare the warranty cost under these warranty execution functions when the product life distributions are Exponential and Weibull, respectively.

We use covered warrants with underlying assets of Taiwan Semiconductor and Hon Hai Precisions traded in the Taiwan Stock Exchange (TWSE) from 2012 to 2014, and examine whether hedging activity of short warrants impacts the underlying stock in the introduction period. Investors expect an increase in stock price in the introduction period of warrants because hedging call warrants need to buy underlying shares. However, a decrease in stock price is expected when hedging put warrants in the same period. If the hedging phenomenon really impacts on underlying asset prices, investors simply can exploit the opportunity to obtain abnormal returns. Results indicate that the stock price and trading volumes increase when warrants are announced. Significant positive abnormal returns can be generated if investors purchase the underlying shares before and sell after the announcement date.

In this paper we analyze the manner in which the position generated by brokerage delta hedging affects the price of the underlying asset. In order to discuses the relation between the hedging by brokerage and the price of the underlying assets at the introduction, during the intermediate, and at the expiration of the warrant. We use the warrants with the underlying assets of Taiwan Semiconductor Manufacturing Company (TSMC) and Soft-World international Corporation traded in Taiwan Stock Exchange from 2014 to 2016. In Taiwan, brokerage has to buy(sell) delta ratio of the underlying assets to hedge when the call(sell) warrants issue. During the intermediate, they adjust the hedging position by the delta. At the expiration date, they have to rebalance the position until maturity of warrants by hedging. In the past, the research found out there was a little evidence that warrants trading had a significant impact on the underlying stock price but confirmed that the stock price would be close to the strike price when the warrants close to maturity. The main purpose of this paper is to explore whether the delta hedging will have an impact on the stock price. The result show that our hypothesis 1 was rejected, the relation between hedging and underlying assets stock price was significant negative. And accepted the hypothesis 2, the delta hedging by brokerage under the volatility effects was significant negative. We assumes that when the brokerage firm takes a continuous delta hedge, this adjustment helps to stabilize the Taiwan market.

The thesis investigates the decreasing time value of warrants, estimated from the theta, implied in Black-Scholes model. By studying the change of time value on warrants, we find that the out of money warrant, firstly, the theta decries with the decreasing duration, since the so called ambiguity of the distribution of underlying stocks. Moreover, we providence the evidence that premium of warrants are distributed by the issuer, moneyness, duration to maturity, trading volume, and the market conditions.

A number of arguments suggest the existence of options listing related effects on underlying stocks, which contains both price and volatility effects. But, the range of studies only involved single-listed option and did not deal with the effects of multiple-listed warrants on the same underlying stocks and the warrants that follow up issuing. This article examines the effects of multiple-listed warrants on the underlying stocks and call warrants from 1997 to 2003 in Taiwan call warrants market. The number of samples includes more than fifty percent of warrants that had been executed in TAIEX on April 2003. The paper use Volume-GARCH one-way and two-ways models to analyze, and design the experimental groups of multiple-listed warrants and the contrastive groups of single-listed warrants. To reduce two troubles that contain the overlap of listed periods and do not consist with the number of listed warrants in the experimental groups from the phenomena of multiple-listed warrants, by the principles of the enlarged or reduced value of Delta, this paper design also the variation percentage of cumulative hedge volume and the weighted cumulative hedge volume as manipulated independent variables. The findings are summarized as follows. First, the effects of price and volatility are different between the experimental groups and the contrastive groups at both direction and degree of the effects that come by the results of this evidence. Secondly, the effects of multiple-listed warrants are significant positive impact on the returns and significant negative impact on the volatility of the stocks over the research periods. The third, the same impact on the return of the stocks within each period of listed warrants are also significant positive, but there are just parts of these to be significant negative impact on their volatility. Finally, the parts of effects are significant positive impact on the returns of the warrants, but the results are not consistently on the volatilities of the warrants from multiple-listed warrants within each period of listed warrants. These results suggest that multiple listed warrants may be an important factor for both decreasing volatility and increasing market value on the underlying stocks, but the effect on each warrant is different. The Contributions of this paper are the innovation of study issue of multiple-listed warrants and the designing construct of manipulated variables might make use of other related studies. By these results of this paper, the Securities and Futures Commission might not need to control multiple listed warrants since the phenomena could decrease volatility on the underlying stocks. The results could make reference to the securities corporations, reconsidering accurately for pricing warrants in primary market and implementing hedging strategies follow-up on the phenomena of multiple-listed warrants. For investors, invest in the underlying stocks, which issue multiple-listed warrants will probably earn abnormal return by the hedging need of trader/ dealer for written positions.

We will examine the relationship between short sales ban and put warrants from Taiwan’s warrant market. Our results show that put warrants trading volume and bid-ask spreads are higher when short sales are banned. We also run 2sls regressions to examine the endogeneity problem that arises. However, we find that warrant market can be substituted for underlying market with short sales ban, but this relationship does not hold strong in the short term when the market switches between banning and not banning short selling.

The paper develops a model of decision making on price, free repairable warranty length and pro-rata warranty length as variables to obtain the maximum profit of a manufacturing firm for a general repairable product under hybrid warranty strategy. The optimal control theory is applied on continuous profit maximization model to analyze and determine the price, free repairable warranty length and pro-rata warranty length for dynamic control path. In order to prove the characters of the above results, The continuous profit maximization model is transferred into the identical discrete profit maximization model. The numerical analysis is used to obtain an optimal solution according to production cost, repairable cost, life distribution of product, and elasticity of demand. Finally, six conclusions are proposed future studies and practical applications.
