Purpose: The aim of this thesis is to investigate whether there is an established investment process for small Swedish service companies, and to what extent they take financial risk into account when making investment decisions.  Theory: The theoretical frame of reference derives from previous research and theories of investment classification, investment processes and risk management in connection with investments.  Method and implementation: The study is based on a qualitative approach through semi-structured interviews with six knowledge-based service companies where the respondents hold positions within company management. A supplementary quantitative method from the companies’ annual reports has been implemented. All the companies surveyed are small Swedish service companies.  Conclusion: The result shows that there is an investment process in all the companies surveyed, though it differs between them. The investments are relevant with the companies’ business strategies. All the companies surveyed take great account of financial risk in investment decisions, mainly by caring for staff in order to retain the human capital in the company. / Syfte: Studien syftar till att undersöka om det finns en fastställd investeringsprocess för småsvenska tjänsteföretag, samt hur och till vilken grad de tar hänsyn till finansiell risk vid investeringsbeslut. Teori: Den teoretiska referensramen härrör tidigare forskning och teorier om investeringsklassificering, investeringsprocesser och riskhantering i samband med investeringar. Metod och genomförande: Studien utgår utifrån ett kvalitativt tillvägagångssätt genom semistrukturerade intervjuer med sex kunskapsbaserade tjänsteföretag där respondenterna innehar positioner inom företagsledningen. En kompletterande kvantitativ datainsamlingsmetod från företagens årsredovisningar har genomförts. Samtliga undersökta företag är små svenska tjänsteföretag med huvudsäte i Stockholm. Slutsats: Studien finner att det i samtliga undersökta företag finns en investeringsprocess, men att den skiljer sig åt mellan företagen. Investeringarna går i linje med företagens verksamhetsstrategi. Samtliga undersökta företag tar stor hänsyn till finansiell risk vid investeringsbeslut, främst genom att vårda personal för att behålla humankapitalet i företaget.

This study investigates the effect of leverage on stock returns on Swedishlisted firms (Large and Mid-cap). Stock returns have been calculated, andleverage ratios have been collected through Datastream. The results contradictfundamental theories on capital structure. According to the fundamentaltheories there should be a positive relationship, but the result of this studysuggests that the relationship is negative.

This thesis gives an example of assessing the risk of a financial portfolio with international assets, where the assets may be of different classes, by the use of Monte Carlo simulation and Extreme Value Theory. The simulation uses univariate modelling, models of the assets’ returns as stochastic processes, as well as vine copulas to create dependency between the variables. For the asset returns a modified version of a discretized Merton jump diffusion model was used. The risk assessment used Extreme Value Theory to calculate Value at Risk and Expected Shortfall of the simulated portfolio. However, the resulting return distribution, and the risk assessment thereof, was not entirely satisfactory due to unreasonably large values ascertained. / Denna uppsats ger ett exempel på hur riskbedömning av finanisella portföljer med internationella tillgångar av olika tillgångsslag genom Monte Carlo simulering och extremvärdesteori. Simuleringen använder univariat modelling, modeller för tillgångarnas avkastningar som stokastiska processer, såväl som vine-copulas för att skapa ett beroende mellan tillgångarna. Tillgångarnas avkastningar modellerades med en modifierad version av en diskretiserad Merton-jump-diffusion model. Riskbedömningen använde extremvärdesteori för att beräkna Value-at-Risk och Expected-Shortfall. Dock blev den resulterande avkastningsfördelningen och riskbedömningen därav inte helt tillfredsällande på grund av att orimligt stora värden erhölls.

Despite the growing body of research in related disciplines, including economics, management, politics, psychology, and sociology, marketing research has largely overlooked the downstream consequences of economic inequality, despite its undeniable impact on individuals' consumption decisions and experiences. This dissertation endeavors to bridge this knowledge gap by uncovering two novel consumer consequences of economic inequality. To accomplish this, it draws upon a diverse range of data sources, including individual-level experimental and survey data, as well as aggregate-level transaction and census data. Additionally, it examines economic inequality across multiple levels, encompassing communities, counties, states, and countries, and operationalizes it both as objective and perceived economic inequality. In Essay 1, I investigate how economic inequality in a consumer's region affects their access to peer-to-peer (P2P) services. Across diverse types of P2P services, I find convergent evidence that increased economic inequality in a consumer's region reduces providers' willingness to serve them, ultimately resulting in their diminished access to P2P services. This adverse effect of economic inequality can be attributed to providers perceiving consumers from more unequal regions as less trustworthy. This perception leads them to perceive heightened financial risks associated with serving these consumers. Moreover, this negative impact of economic inequality attenuates when providers perceive greater interpersonal similarity with consumers from unequal regions. In Essay 2, I explore how economic inequality within one's society affects their education decisions through the lens of perceived education premium. Firstly, it encourages people to attend college as it amplifies the perceived education premium of college—the income gap between college graduates and high school graduates. Secondly, it motivates people to choose majors with higher earning potential but lower personal interests, as opposed to those that align more with their genuine interests but pay less. This shift towards prioritizing extrinsic motivations over intrinsic ones is driven by people's perception of a more significant education premium between majors—the income disparity between higher-paying and lower-paying majors. / Doctor of Philosophy / Economic inequality, defined as the unequal distribution of income among various groups in a society, has been on the rise globally in recent decades. Amid the growing economic inequality, researchers have been delving into its profound impacts on individuals across diverse domains, exploring its influences on their mindsets, perspectives on the world, social lives, and overall well-being. It's surprising that there has been relatively little research on how economic inequality affects people's consumption decisions and experiences, given its undeniable influence on them. In this dissertation, I explore the impacts of economic inequality on consumers' access to P2P services and education decision-making. In Essay 1, I investigate how economic inequality in a consumer's region affects their access to peer-to-peer (P2P) services. I examine whether P2P providers are equally willing to serve consumers from regions with varying levels of economic inequality. I reveal a disconcerting reality: providers are less willing to offer P2P services to consumers from more unequal regions, driven by the perception of these consumers as less trustworthy and posing a higher financial risk. These differing attitudes ultimately lead to reduced access to P2P services and region-based discrimination for consumers from regions characterized by higher economic inequality. Fortunately, these adverse outcomes can be mitigated by an increase in perceived interpersonal similarity between providers and consumers. In Essay 2, I investigate how economic inequality in one's society shapes their education decisions. I find that as economic inequality rises, people become more willing to pursue a college education because they perceive a wider income gap between well-educated individuals and those with lower levels of education. Besides college decisions, economic inequality also influences people's choice of major for a similar reason. In a society characterized by greater economic inequality, people gravitate towards majors that promise higher earning potential, even if these fields do not align closely with their personal interests. This preference is driven by their perception of a greater wage difference between higher- and lower-paying majors. These findings provide policy implications for several pressing challenges in higher education.

This study aims to analyse the changes in the capital structure of Swedish real estate companies over the past five years, with a particular focus on the period 2022-2023, characterised by the policy interest rate increasing from zero to 3.5 percent. The study further explores the potential risks these companies face concerning interest rate exposure and liquidity. The research process involves a comprehensive literature review, quantitative analysis of financial key figures, and qualitative interviews with banks and consultants in the real estate market. The findings suggest that the capital structure of real estate companies is highly influenced by the cost of capital and the companies’ credit ratings. While large companies with the highest credit ratings have coped with increased capital costs in the bond market and continue issuing bonds, remaining investment grade companies have turned to the bank sector as the prices in the bond market have increased. Increased competition in bank financing has made the banks more selective, prioritising existing customers and making it challenging for high-yield and non-existing bank customers to secure debt. The high demand for bank financing further opens up possibilities for alternative financing to increase market shares. As a consequence of escalated risk in the real estate sector, financiers are increasing credit margins and implementing stricter credit terms. A key factor for assessing the risk in today’s market is the capability of the cash flow to cover the rising cost of capital, exposing the low- yielding residential segment. To mitigate liquidity risk, the findings suggest an increased need for equity and expected share issuance and asset sales. However, a stress test conducted based on the Interest coverage ratio suggests that the real estate market is able to handle additional interest rate increases, not facing alarming distress until interest rates increase by an additional 3%. By examining theories such as the Pecking Order and Trade-off Theory, this research contributes to the existing literature, shedding light on the evolving capital structure of Swedish real estate companies and the impact of interest rate fluctuations on financing strategies and risk evaluation. / Denna studie syftar till att analysera trender i svenska fastighetsbolags kapitalstruktur under de senaste fem åren, med fokus på perioden 2022-2023, färgad av höjningar i Riksbankens styrränta från noll till 3.5%. Studien utforskar även potentiella risker för fastighetsbolag avseende ränta och likviditet. Forskningsprocessen inkluderar en omfattande litteraturgenomgång, kvantitativ analys av finansiella nyckeltal och kvalitativa intervjuer med banker och konsulter på fastighetsmarknaden. Resultaten antyder att kapitalstrukturen för fastighetsbolag i hög grad påverkas av kapitalkostnad och företagens kreditbetyg. Medan stora företag med högsta kreditbetyg har kunnat hantera ökade kapitalkostnader på obligationsmarknaden och fortsätter att emittera obligationer, har återstående företag med investment grade rating vänt sig till banksektorn när priserna på obligationsmarknaden har ökat. Ökad konkurrens för bankfinansiering har gjort bankerna mer selektiva, med prioritet för befintliga kunder, vilket har gjort det utmanande för high-yield betygsatta och icke-existerande bankkunder att säkra skulder. Den höga efterfrågan på bankfinansiering öppnar också upp möjligheter för alternativ finansiering att öka i marknadsandel. Som en följd av ökad risk inom fastighetssektorn ökar finansiärer kreditmarginalerna och inför striktare kreditvillkor. En viktig faktor för att bedöma risken på dagens marknad är förmågan hos kassaflödet att täcka den stigande kapitalkostnaden, vilket exponerar det lågavkastande bostadssegmentet. För att minska likviditetsrisken antyder resultaten ett ökat behov av eget kapital och förväntade aktieemissioner och försäljningar av tillgångar. Studien inkluderar ett stresstest genomfört baserat på räntetäckningsgraden, vilket emellertid antyder att fastighetsmarknaden klarar av ytterligare räntehöjningar och uppnår ordentliga finansiella svårigheter först vid en räntehöjning på ytterligare 3 procentenheter från dagens läge. Genom att undersöka teorier som Pecking Order och Trade-off Theory bidrar denna forskning till befintlig litteratur och belyser den utvecklande kapitalstrukturen för svenska fastighetsbolag samt påverkan av räntefluktuationer på finansieringsstrategier och riskbedömning.

The study focuses on tariff-linked (or commodity-linked) agreements entered into between a power utility and commodity producers. The main purpose of these types of agreements is to link electricity tariff payable by commodity producers to the price of the commodity produced thereby transferring a certain level of commodity price risk to the power utility. The study looks at risk management practices of a power utility company with a particular reference to tariff-linked agreements. Also, the study critically analyses risk hedging mechanisms put in place by the power utility. The report makes practical recommendations, where applicable, in dealing with these risks. Risk management continuously evolve to meet the challenges of complex financial world. Despite the latest sophisticated risk management tools available commodity producers still encounter difficulties to hedge the price risk. The challenge for the power utility is the application of new risk management tools to effectively manage price risk. / Business Management / M.Com. (Business Economics)

Operational risk has become an increasingly important topic within financial institutions of late, resulting in an increased spend by financial service organisations on operational risk management solutions. While this move is positive, evidence has shown that information technology implementations have tended to have low rates of success. Research highlighted that a series of defined critical success factors could reduce the risk of implementation failure. Investigations into the literature revealed that no critical success factors had been defined for the implementation of an operational risk management system. Through a literature study, a list of 29 critical success factors was identified. To confirm these factors, a questionnaire was developed. The questionnaire was distributed to an identified target audience within the South African financial services community. Reponses to the questionnaire revealed that 27 of the 29 critical success factors were deemed important and critical to the implementation of an operational risk management system. / Business Management / M.

This thesis investigates correlations and linkages in credit risk that widely exist in all sectors of the financial markets. The main body of this thesis is constructed around four empirical chapters. I started with extending two main issues focused by earlier empirical studies on credit derivatives markets: the determinants of CDS spreads and the relationship between CDS spreads and bond yield spreads, with a special focus on the effect of the subprime crisis. By having observed that the linear relationship can not fully explain the variation in CDS spreads, the third empirical chapter investigated the dependence structure between CDS spread changes and market variables using a nonlinear copula method. The last chapter investigated the relationship between the CDS spread and another credit spread - the TED spread, in that a MVGARCH model and twelve copulas are set forth including three time varying copulas. The results of this thesis greatly enhanced our understanding about the effect of the subprime crisis on the credit default swap market, upon which a set of useful practical suggestions are made to policy makers and market participants.

Thesis (MSc)--Stellenbosch University, 2015 / ENGLISH ABSTRACT : In recent years, the use of Lévy processes as a modelling tool has come to be viewed more favourably than the use of the classical Brownian motion setup. The reason for this is that these processes provide more flexibility and also capture more of the ’real world’ dynamics of the model. Hence the use of Lévy processes for financial modelling is a motivating factor behind this research presentation. As a starting point a framework for the LIBOR market model with dynamics driven by a Lévy process instead of the classical Brownian motion setup is presented. When modelling LIBOR rates the use of a more realistic driving process is important since these rates are the most realistic interest rates used in the market of financial trading on a daily basis. Since the financial crisis there has been an increasing demand and need for efficient modelling and management of risk within the market. This has further led to the motivation of the use of Lévy based models for the modelling of credit risky financial instruments. The motivation stems from the basic properties of stationary and independent increments of Lévy processes. With these properties, the model is able to better account for any unexpected behaviour within the market, usually referred to as "jumps". Taking both of these factors into account, there is much motivation for the construction of a model driven by Lévy processes which is able to model credit risk and credit risky instruments. The model for LIBOR rates driven by these processes was first introduced by Eberlein and Özkan (2005) and is known as the Lévy-LIBOR model. In order to account for the credit risk in the market, the Lévy-LIBOR model with default risk was constructed. This was initially done by Kluge (2005) and then formally introduced in the paper by Eberlein et al. (2006). This thesis aims to present the theoretical construction of the model as done in the above mentioned references. The construction includes the consideration of recovery rates associated to the default event as well as a pricing formula for some popular credit derivatives. / AFRIKAANSE OPSOMMING : In onlangse jare, is die gebruik van Lévy-prosesse as ’n modellerings instrument baie meer gunstig gevind as die gebruik van die klassieke Brownse bewegingsproses opstel. Die rede hiervoor is dat hierdie prosesse meer buigsaamheid verskaf en die dinamiek van die model wat die praktyk beskryf, beter hierin vervat word. Dus is die gebruik van Lévy-prosesse vir finansiële modellering ’n motiverende faktor vir hierdie navorsingsaanbieding. As beginput word ’n raamwerk vir die LIBOR mark model met dinamika, gedryf deur ’n Lévy-proses in plaas van die klassieke Brownse bewegings opstel, aangebied. Wanneer LIBOR-koerse gemodelleer word is die gebruik van ’n meer realistiese proses belangriker aangesien hierdie koerse die mees realistiese koerse is wat in die finansiële mark op ’n daaglikse basis gebruik word. Sedert die finansiële krisis was daar ’n toenemende aanvraag en behoefte aan doeltreffende modellering en die bestaan van risiko binne die mark. Dit het verder gelei tot die motivering van Lévy-gebaseerde modelle vir die modellering van finansiële instrumente wat in die besonder aan kridietrisiko onderhewig is. Die motivering spruit uit die basiese eienskappe van stasionêre en onafhanklike inkremente van Lévy-prosesse. Met hierdie eienskappe is die model in staat om enige onverwagte gedrag (bekend as spronge) vas te vang. Deur hierdie faktore in ag te neem, is daar genoeg motivering vir die bou van ’n model gedryf deur Lévy-prosesse wat in staat is om kredietrisiko en instrumente onderhewig hieraan te modelleer. Die model vir LIBOR-koerse gedryf deur hierdie prosesse was oorspronklik bekendgestel deur Eberlein and Özkan (2005) en staan beken as die Lévy-LIBOR model. Om die kredietrisiko in die mark te akkommodeer word die Lévy-LIBOR model met "default risk" gekonstrueer. Dit was aanvanklik deur Kluge (2005) gedoen en formeel in die artikel bekendgestel deur Eberlein et al. (2006). Die doel van hierdie tesis is om die teoretiese konstruksie van die model aan te bied soos gedoen in die bogenoemde verwysings. Die konstruksie sluit ondermeer in die terugkrygingskoers wat met die wanbetaling geassosieer word, sowel as ’n prysingsformule vir ’n paar bekende krediet afgeleide instrumente.
