Tavoite on selvittää hinnoittelupäätöksien noudattamista ohjelmistoliiketoimintaa harjoittavassa yrityksessä. Lisäksi syitä noudattamiseen ja noudattamatta jättämiseen sekä asiakkaiden hinnoittelutoiveisiin selvitettiin. Teoriassa esitellään kolmea hinnoittelumallia, kuinka näitä malleja käytetään käytännössä? Teoriaosuudessa käsitellään hintaa, hinnoittelua, hinnoittelumalleja ja ohjelmistoliiketoiminnan piirteitä. Empiirisessä osassa tehdään laadullista tutkimusta henkilökohtaisilla puolistrukturoiduilla haastatteluilla, joista kerätään tarjousten kanssa tutkimuksen aineisto. Tutkimusmateriaalin pohjalta vastataan tutkimuskysymyksiin. Vaikka käytännöt olisivat valideja, mutta mikäli hintoja ei nähdä järkevinä, käytännöistä on joustettava. Kohdetuotteilla pitäisi myös olla yhtäläiset hinnoittelumallit. Pääsyyksi käytännöistä joustamiseen nähtiin kohdeasiakkaan olevan avainasiakas tai kilpailijan tarjouksen voittaminen.

Digitalization and technology megatrends such as Cloud services have provided SMEs with a suitable atmosphere and conditions to internationalize and seek for further business growth. There is a limited amount of research on Cloud services from the business perspective and the limitations and challenges SMEs encounter when pursuing international business growth. Thus, the main research question of this study was how Cloud services may enable Finnish SMEs to overcome international growth challenges. The research question was further divided into three sub-questions dealing with matters related to features and characteristics of Cloud services, limitations and challenges Finnish SMEs experience when pursuing international growth of business, and benefits and advantages of utilizing Cloud services to mitigate and suppress international growth challenges. First, the theoretical framework of this study was constructed based on the existing literature on Cloud services, SMEs, and international growth challenges. After this, qualitative research approach and methodology were applied for this study. The data was collected through six semi-structured expert interviews in person with representatives of IBM, Exidio, Big Data Solutions, and Comptel. After analyzing the collected data by applying thematic analysis method, the results were compared with the existing theory and the original framework was modified and complemented accordingly. Resource scarcity, customer base expansion and retention, and lack of courage to try new things and take risks turned out to be major international growth challenges of Finnish SMEs. Due to a number of benefits and advantages of utilizing Cloud services including service automation, consumption-based pricing model, lack of capital expenditures (capex) and huge upfront investments, lightened organization structure, cost savings, speed, accessibility, scalability, agility, geographical expansion potential, global reaching and covering, credibility, partners, enhanced CRM, freedom, and flexibility, it can be concluded that Cloud services can help directly and indirectly Finnish SMEs to mitigate and overcome international growth challenges and enable further business growth.

Small investors' sentiment has been proposed by behaviouralists to explain the existence and behavior of discount on closed-end funds (CEFD). The empirical tests of this sentiment hypothesis so far provide equivocal results. Besides, most of out-of-sample tests outside U.S. are not robust in the sense that they fail to well control other firm characteristics and risk factors that may explain stock return and to provide a formal cross-sectional test of the link between CEFD and stock return. This thesis explores the role of CEFD in asset pricing and further validates CEFD as a sentiment proxy in Canadian context and augments the extant studies by examining the redemption feature inherent in Canadian closed-end funds and by enhancing the robustness of the empirical tests. Our empirical results document differential behaviors in discounts between redeemable funds and non-redeemable funds. However, we don't find supportive evidence of CEFD as a priced factor. Specifically, the stocks with different exposures to CEFD fail to provide significantly different average return. Nor does CEFD provide significant incremental explanatory power, after controlling other well-known firm characteristics and risk factors, in cross-sectional as well as time-series variation of stock return. This evidence, together with the findings from our direct test of CEFD as a sentiment index, suggests that CEFD, even the discount on traditional non-redeemable closed-end funds, is unlikely to be driven by elusive sentiment in Canada.

Le problème de tarification qui nous intéresse ici consiste à maximiser le revenu généré par les usagers d'un réseau de transport. Pour se rendre à leurs destinations, les usagers font un choix de route et utilisent des arcs sur lesquels nous imposons des tarifs. Chaque route est caractérisée (aux yeux de l'usager) par sa "désutilité", une mesure de longueur généralisée tenant compte à la fois des tarifs et des autres coûts associés à son utilisation. Ce problème a surtout été abordé sous une modélisation déterministe de la demande selon laquelle seules des routes de désutilité minimale se voient attribuer une mesure positive de flot. Le modèle déterministe se prête bien à une résolution globale, mais pèche par manque de réalisme. Nous considérons ici une extension probabiliste de ce modèle, selon laquelle les usagers d'un réseau sont alloués aux routes d'après un modèle de choix discret logit. Bien que le problème de tarification qui en résulte est non linéaire et non convexe, il conserve néanmoins une forte composante combinatoire que nous exploitons à des fins algorithmiques. Notre contribution se répartit en trois articles. Dans le premier, nous abordons le problème d'un point de vue théorique pour le cas avec une paire origine-destination. Nous développons une analyse de premier ordre qui exploite les propriétés analytiques de l'affectation logit et démontrons la validité de règles de simplification de la topologie du réseau qui permettent de réduire la dimension du problème sans en modifier la solution. Nous établissons ensuite l'unimodalité du problème pour une vaste gamme de topologies et nous généralisons certains de nos résultats au problème de la tarification d'une ligne de produits. Dans le deuxième article, nous abordons le problème d'un point de vue numérique pour le cas avec plusieurs paires origine-destination. Nous développons des algorithmes qui exploitent l'information locale et la parenté des formulations probabilistes et déterministes. Un des résultats de notre analyse est l'obtention de bornes sur l'erreur commise par les modèles combinatoires dans l'approximation du revenu logit. Nos essais numériques montrent qu'une approximation combinatoire rudimentaire permet souvent d'identifier des solutions quasi-optimales. Dans le troisième article, nous considérons l'extension du problème à une demande hétérogène. L'affectation de la demande y est donnée par un modèle de choix discret logit mixte où la sensibilité au prix d'un usager est aléatoire. Sous cette modélisation, l'expression du revenu n'est pas analytique et ne peut être évaluée de façon exacte. Cependant, nous démontrons que l'utilisation d'approximations non linéaires et combinatoires permet d'identifier des solutions quasi-optimales. Finalement, nous en profitons pour illustrer la richesse du modèle, par le biais d'une interprétation économique, et examinons plus particulièrement la contribution au revenu des différents groupes d'usagers.

La valoración de una empresa como sistema dinámico es bastante compleja, los diferentes modelos o métodos de valoración son una aproximación teórica y por consiguiente simplificadora de la realidad. Dichos modelos, se aproximan mediante supuestos o premisas estadísticas que nos permiten hacer dicha simplificación, ejemplos de estos, son el comportamiento del inversionista o la eficiencia del mercado. Bajo el marco de un mercado emergente, este proceso presenta de indistinta forma retos paracualquier método de valoración, dado a que el mercado no obedece a los paradigmas tradicionales. Lo anterior hace referencia a que la valoración es aún más compleja, dado que los inversionistas se enfrentan a mayores riesgos y obstáculos. Así mismo, a medida que las economías se globalizan y el capital es más móvil, la valoración tomaráaún más importancia en el contexto citado. Este trabajo de gradopretende recopilar y analizar los diferentes métodos de valoración, además de identificar y aplicar aquellos que se reconocen como “buenas prácticas”. Este proceso se llevó a cabo para una de las empresas más importantes de Colombia, donde fundamentalmente se consideró el contexto de mercado emergente y específicamente el sector petrolero, como criterios para la aplicación del tradicional DCF y el práctico R&V.

Decision theory is the study of models of judgement involved in, and leading to, deliberate and (usually) rational choice. In real estate investment there are normative models for the allocation of assets. These asset allocation models suggest an optimum allocation between the respective asset classes based on the investors’ judgements of performance and risk. Real estate is selected, as other assets, on the basis of some criteria, e.g. commonly its marginal contribution to the production of a mean variance efficient multi asset portfolio, subject to the investor’s objectives and capital rationing constraints. However, decisions are made relative to current expectations and current business constraints. Whilst a decision maker may believe in the required optimum exposure levels as dictated by an asset allocation model, the final decision may/will be influenced by factors outside the parameters of the mathematical model. This paper discusses investors' perceptions and attitudes toward real estate and highlights the important difference between theoretical exposure levels and pragmatic business considerations. It develops a model to identify “soft” parameters in decision making which will influence the optimal allocation for that asset class. This “soft” information may relate to behavioural issues such as the tendency to mirror competitors; a desire to meet weight of money objectives; a desire to retain the status quo and many other non-financial considerations. The paper aims to establish the place of property in multi asset portfolios in the UK and examine the asset allocation process in practice, with a view to understanding the decision making process and to look at investors’ perceptions based on an historic analysis of market expectation; a comparison with historic data and an analysis of actual performance.

The article examines whether commodity risk is priced in the cross-section of global equity returns. We employ a long-only equally-weighted portfolio of commodity futures and a term structure portfolio that captures phases of backwardation and contango as mimicking portfolios for commodity risk. We find that equity-sorted portfolios with greater sensitivities to the excess returns of the backwardation and contango portfolio command higher average excess returns, suggesting that when measured appropriately, commodity risk is pervasive in stocks. Our conclusions are robust to the addition to the pricing model of financial, macroeconomic and business cycle-based risk factors.

Na utilização de variados tipos de financiamento, a empresa necessita, primariamente, da análise do custo do capital - custo básico para remuneração dos recursos próprios e de terceiros que compõem a estrutura de capital - o qual deve ser a taxa referencial para haver retorno do investimento e geração_ de valor, emergindo, por conseguinte, a discussão acerca da repercussão do nível de endividamento, e, conseqüentemente, do custo de capital sobre o valor da empresa. Nesse contexto, existem modelos que consideram o endividamento irrelevante no valor da empresa, como: análise pelo Lucro Operacional ou de Modiglianni e Miller sem Imposto de Renda. Em outro extremo, há abordagens que o têm como função direta para o valor, como a do Lucro Líquido e de Modigliani e Miller com imposto de renda. Entre essas posições antagônicas podem ser citadas a posição Tradicional e do Custo de Dificuldades Financeiras, que admitem a influência do endividamento após determinado nível de alavancagem. A Teoria da Informação Assimétrica, por sua vez, sustenta ser a sinalização enviada com mudanças na estrutura de capital fator de influência no valor da empresa. No modelo de avaliação por Opções, argumenta-se que, dentro de determinadas hipóteses, a riqueza dos acionistas é incrementada por uma alavancagem financeira mais elevada. A avaliação em situação de incerteza para a empresa é refletida no modelo que utiliza o Capital Asset Price Model, onde argumenta-se que um aumento no endividamento eleva o beta e, conseqüentemente, o retorno esperado. Por último, há a análise baseada em fluxos de caixa onde o valor presente da empresa é adicionado ao valor presente líquido dos efeitos intrínsecos ao financiamento. O cálculo do valor da empresa também pode ser feito através do fluxo de caixa do acionista descontado pela taxa de remuneração do capital próprio ou fluxo operacional descontado pelo custo médio ponderado do capital, subtraindo o valor do endividamento. Este trabalho se propôs a analisar, durante o período 1994-1998, a relação do endividamento com o custo médio ponderado do capital e com valor de mercado de oito empresas, componentes de amostra representativa do setor siderúrgico brasileiro, e também a estimar o valor do capital próprio, através do modelo de desconto do fluxo de caixa operacional pelo custo médio ponderado do capital, verificando a aderência dessa avaliação, através de comparação com o valor de mercado observado. Pela análise dos resultados observamos, uma relação inversa entre custo médio do capital e endividamento. No que se refere à avaliação da empresa, o modelo apresentado de desconto pelo custo médio ponderado do capital, revelou-se de modo geral, satisfatório, com o valor estimado explicando 68% do valor de mercado, na análise da regressão; sendo que as maiores distorções foram verificadas nas empresas que tiveram grau de alavancagem elevado.

A integração estocástica é a ferramenta básica para o estudo do apreçamento de ativos derivados1 nos modelos de finanças de tempo contínuo. A fórmula de Black e Scholes é o exemplo mais conhecido. Os movimentos de preços de ações, são frequentemente modelados - tanto teóricamente quanto empÍricamente - como seguindo uma equação diferencial estocástica. O livro texto de D. Duflle, "Dynamic asset pricing theory)) 1 usa livremente conceitos como o teorema de Girsanov e a fórmula de Feynrnan-Kac. U fi conhecimento básico da integração estocástica é cada vez mais necessário para quem quer acompanhar a literatura moderna em finanças. Esta introdução à integração estocástica é dirigida para alunos de doutourado e no final de mestrado. Um conhecimento sólid02 de continuidade, limites e facilidade de operar com a notação de conjuntos é fundamental para a compreensão do texto que se segue. Um conhecimento básico de integral de Lebesgue é recomendável. No entanto incluí no texto as definições básicas e os resultados fundamentais da teoria da integral de Lebesgue usados no texto.

I study the asset-pricing implications in an cnviromncnt with feedback traders and rational arbitrageurs. Feedback traders are defined as possible naive investors who buy after a raise in prices and sell after a drop in prices. I consider two types of feedback strategies: (1) short-term (SF), motivated by institutional rulcs as top-losscs and margin calls and (2) long-tcrm (LF), motivated by representativeness bias from non-sophisticated investors. Their presence in the market follows a stochastic regime swift process. Short lived assumption for the arbitrageurs prevents the correction of the misspricing generated by feedback strategies. The estimated modcl using US data suggests that the regime switching is able to capture the time varying autocorrclation of returns. The segregation of feedback types helps to identify the long term component that otherwise would not show up due to the large movements implied by the SF typc. The paper also has normativo implications for practioners since it providos a methodology to identify mispricings driven by feedback traders.
