Avaliação de projetos de mineração utilizando a teoria das opções reais em tempo discreto : um estudo de caso em mineração de ferro

Estudo da teoria das opções reais que incorpora à avaliação de projetos de investimentos, as opções de crescimento e as flexibilidades gerenciais que surgem devido às incertezas existentes no ambiente no qual as empresas operam. Aborda os métodos tradicionais de avaliação de investimentos baseados no fluxo de caixa descontado (FCD), destaca as suas vantagens e limitações; a teoria das opções reais mostrando suas vantagens em relação aos métodos tradicionais; e um estudo de caso. Tem como objetivo principal apresentar que a teoria das opções reais é viável e complementar aos métodos tradicionais de avaliação de investimentos na indústria de mineração de ferro, com a abordagem da avaliação em tempo discreto. Este método permite especificar o problema de análise e resolvê-lo com o uso de programa de software de análise de decisão disponível no mercado de forma mais simples e mais intuitivo que os métodos tradicionais de avaliação de opções reais e permite maior flexibilidade na modelagem do problema de avaliação. A modelagem das opções reais do projeto baseia-se no uso de árvore de decisão binomial para modelar o processo estocástico. A avaliação é realizada em quatro passos de acordo com a metodologia proposta por Copeland e Antikarov (2001) e Brandão e Dyer (2005): modelagem do ativo básico, ou seja, cálculo do valor presente líquido sem flexibilidade; criação do modelo binomial utilizando o software computacional para modelar o ativo básico, computando as probabilidades neutras a risco; modelagem das opções reais no projeto; e resolução da árvore binomial, ou seja, análise das opções reais. Os resultados apresentados demonstram que é possível implementar a abordagem da avaliação de opções reais em projetos de investimentos na indústria de mineração de ferro.

Avaliação de projetos de investimento em cogeração de energia utilizando bagaço de cana-de-açúcar em biorrefinarias a partir do uso da teoria das opções reais

O cenário de continuo aumento do consumo de derivados do petróleo aliado a conscientização de que é necessário existir um equilíbrio com relação a exploração de recursos naturais e preservação do meio ambiente, vem impulsionando a busca por fontes alternativas de energia. Esse crescente interesse vem se aplicando a geração de energia a partir de biomassa da cana de açúcar, que vem se tornando cada vez mais comuns no Brasil, porém ainda existe um imenso potencial a ser explorado. Dentro deste contexto, se torna relevante a tomada de decisão de investimentos em projetos de cogeração e este trabalho busca incrementar a analise e tomada de decisão com a utilização da Teoria das Opções Reais, uma ferramenta de agregação de valor às incertezas, cabendo perfeitamente ao modelo energético brasileiro, onde grandes volatilidades do preço de energia são observadas ao longo dos anos. O objetivo do trabalho é determinar o melhor momento para uma biorrefinaria investir em unidades de cogeração. A estrutura do trabalho foi dividida em três cenários de porte de biorrefinarias, as de 2 milhões de capacidade de moagem de cana-de-açúcar por ano, as de 4 milhões e as de 6 milhões, visando assim ter uma representação amostral das biorrefinarias do país. Além disso, analisaram-se três cenários de volatilidade atrelados ao preço futuro de energia, dado que a principal variável de viabilização deste tipo de projeto é o preço de energia. As volatilidades foram calculadas de acordo com histórico do ambiente regulado, o dobro do ambiente regulado e projeção de PLD, representando, respectivamente, níveis baixos, médios e altos, de volatilidade do preço de energia. Após isso, foram elaboradas as nove árvores de decisão, que demonstram para os gestores de investimento que em um cenário de baixa volatilidade cria-se valor estar posicionado e ter a opção real de investir ou adiar investimento para qualquer porte de usina. No cenário de média volatilidade de preço, aconselha-se ao gestor estar posicionado em usinas de médio a grande porte para viabilização do investimento. Por fim, quando o cenário de preços é de grande volatilidade, tem-se um maior risco e existe a maior probabilidade de viabilização do investimento em usinas de grande porte.

Estimação do desconto de reequilíbrio ótimo em concessões rodoviárias através da metodologia das opções reais

Este trabalho propõe um novo modelo para avaliação, em tempo discreto, do desconto de reequilíbrio em contratos de concessão rodoviária, a partir de conceitos da Teoria Clássica de Finanças e da Teoria de Opções Reais. O modelo desenvolvido permitiu incorporar flexibilidades decorrentes de incertezas nas situações reais, como decisões gerenciais, vieses de comportamento e componentes políticos, comumente presentes em contratos de concessões rodoviária. Os resultados obtidos, utilizando-se como estudo de caso a BR-262, sinalizaram que há espaço para uma melhor intervenção regulatória com relação ao mecanismo do desconto de reequilíbrio, no sentido de prover melhores incentivos aos concessionários.

Análise de investimento em confinamento bovino no centro-oeste brasileiro: um estudo de caso.

This study analyzed the economic viability of an investment in feedlot cattle on a farm in the midsize state of Goias. The research identified that different thematic studies whose interests have focused mainly on cost analysis and profitability punctual. Differently, this study used the approaches of the Discounted Cash Flow (DCF) and the Real Options Theory (ROT). The first used the projected cash flow for 10 years and a discount rate determined by CAPM at 8% p.a. for containment of heads 400. The second was modeled by the binomial model of Cox, Ross and Rubinstein (1979) incorporating the option of waiting. This methodology has not been employed in Brazilian cattle industry. The search results pointed to the economic viability of the project when considered possible scenarios for the different price ranges of the ox that state bushel. In addition, the TOR proved to be a more robust tool for investment analysis, by incorporating the flexibility of farmers to wait for the right time to make the confinement.

Technology acquisition through licensing. Implications for firm strategy

Nowadays licensing practices have increased in importance and relevance driving the widespread diffusion of markets for technologies. Firms are shifting from a tactical to a strategic attitude towards licensing, addressing both business and corporate level objectives. The Open Innovation Paradigm has been embraced. Firms rely more and more on collaboration and external sourcing of knowledge. This new model of innovation requires firms to leverage on external technologies to unlock the potential of firms’ internal innovative efforts. In this context, firms’ competitive advantage depends both on their ability to recognize available opportunities inside and outside their boundaries and on their readiness to exploit them in order to fuel their innovation process dynamically. Licensing is one of the ways available to firm to ripe the advantages associated to an open attitude in technology strategy. From the licensee’s point view this implies challenging the so-called not-invented-here syndrome, affecting the more traditional firms that emphasize the myth of internal research and development supremacy. This also entails understanding the so-called cognitive constraints affecting the perfect functioning of markets for technologies that are associated to the costs for the assimilation, integration and exploitation of external knowledge by recipient firms. My thesis aimed at shedding light on new interesting issues associated to in-licensing activities that have been neglected by the literature on licensing and markets for technologies. The reason for this gap is associated to the “perspective bias” affecting the works within this stream of research. With very few notable exceptions, they have been generally concerned with the investigation of the so-called licensing dilemma of the licensor – whether to license out or to internally exploit the in-house developed technologies, while neglecting the licensee’s perspective. In my opinion, this has left rooms for improving the understanding of the determinants and conditions affecting licensing-in practices. From the licensee’s viewpoint, the licensing strategy deals with the search, integration, assimilation, exploitation of external technologies. As such it lies at the very hearth of firm’s technology strategy. Improving our understanding of this strategy is thus required to assess the full implications of in-licensing decisions as they shape firms’ innovation patterns and technological capabilities evolution. It also allow for understanding the so-called cognitive constraints associated to the not-invented-here syndrome. In recognition of that, the aim of my work is to contribute to the theoretical and empirical literature explaining the determinants of the licensee’s behavior, by providing a comprehensive theoretical framework as well as ad-hoc conceptual tools to understand and overcome frictions and to ease the achievement of satisfactory technology transfer agreements in the marketplace. Aiming at this, I investigate licensing-in in three different fashions developed in three research papers. In the first work, I investigate the links between licensing and the patterns of firms’ technological search diversification according to the framework of references of the Search literature, Resource-based Theory and the theory of general purpose technologies. In the second paper - that continues where the first one left off – I analyze the new concept of learning-bylicensing, in terms of development of new knowledge inside the licensee firms (e.g. new patents) some years after the acquisition of the license, according to the Dynamic Capabilities perspective. Finally, in the third study, Ideal with the determinants of the remuneration structure of patent licenses (form and amount), and in particular on the role of the upfront fee from the licensee’s perspective. Aiming at this, I combine the insights of two theoretical approaches: agency and real options theory.

Corporate Venture Capital: How established firms use external resources to create new competencies

This Doctoral Dissertation is triggered by an emergent trend: firms are increasingly referring to investments in corporate venture capital (CVC) as means to create new competencies and foster the search for competitive advantage through the use of external resources. CVC is generally defined as the practice by non-financial firms of placing equity investments in entrepreneurial companies. Thus, CVC can be interpreted (i) as a key component of corporate entrepreneurship - acts of organizational creation, renewal, or innovation that occur within or outside an existing organization– and (ii) as a particular form of venture capital (VC) investment where the investor is not a traditional and financial institution, but an established corporation. My Dissertation, thus, simultaneously refers to two streams of research: corporate strategy and venture capital. In particular, I directed my attention to three topics of particular relevance for better understanding the role of CVC. In the first study, I moved from the consideration that competitive environments with rapid technological changes increasingly force established corporations to access knowledge from external sources. Firms, thus, extensively engage in external business development activities through different forms of collaboration with partners. While the underlying process common to these mechanisms is one of knowledge access, they are substantially different. The aim of the first study is to figure out how corporations choose among CVC, alliance, joint venture and acquisition. I addressed this issue adopting a multi-theoretical framework where the resource-based view and real options theory are integrated. While the first study mainly looked into the use of external resources for corporate growth, in the second work, I combined an internal and an external perspective to figure out the relationship between CVC investments (exploiting external resources) and a more traditional strategy to create competitive advantage, that is, corporate diversification (based on internal resources). Adopting an explorative lens, I investigated how these different modes to renew corporate current capabilities interact to each other. More precisely, is CVC complementary or substitute to corporate diversification? Finally, the third study focused on the more general field of VC to investigate (i) how VC firms evaluate the patent portfolios of their potential investee companies and (ii) whether the ability to evaluate technology and intellectual property varies depending on the type of investors, in particular for what concern the distinction between specialized versus generalist VCs and independent versus corporate VCs. This topic is motivated by two observations. First, it is not clear yet which determinants of patent value are primarily considered by VCs in their investment decisions. Second, VCs are not all alike in terms of technological experiences and these differences need to be taken into account.

Unit Root Analysis of Traffic Time Series in Toll Highways

Concession contracts in highways often include some kind of clauses (for example, a minimum traffic guarantee) that allow for better management of the business risks. The value of these clauses may be important and should be added to the total value of the concession. However, in these cases, traditional valuation techniques, like the NPV (net present value) of the project, are insufficient. An alternative methodology for the valuation of highway concession is one based on the real options approach. This methodology is generally built on the assumption of the evolution of traffic volume as a GBM (geometric Brownian motion), which is the hypothesis analyzed in this paper. First, a description of the methodology used for the analysis of the existence of unit roots (i.e., the hypothesis of non-stationarity) is provided. The Dickey-Fuller approach has been used, which is the most common test for this kind of analysis. Then this methodology is applied to perform a statistical analysis of traffic series in Spanish toll highways. For this purpose, data on the AADT (annual average daily traffic) on a set of highways have been used. The period of analysis is around thirty years in most cases. The main outcome of the research is that the hypothesis that traffic volume follows a GBM process in Spanish toll highways cannot be rejected. This result is robust, and therefore it can be used as a starting point for the application of the real options theory to assess toll highway concessions.

Estudio de opciones reales para decisiones de inversión en un proyecto minero de nueva ejecución

El objetivo principal es desarrollar la metodología de opciones reales para evaluar la posible puesta en marcha de un proyecto minero. Para esto, el proyecto se divide en dos partes: En la primera parte, con carácter teórico se analizan las inversiones desde el punto de vista tradicional, comparando la problemática de estas valoraciones en ambientes de incertidumbre y flexibilidad operativa. Se analizan las opciones financieras y se comparan con las opciones reales, en cuanto a similitudes y problemáticas. Se desarrollan también los procesos estocásticos que afectan a las variables del proyecto de inversión. Se explican además, las metodologías para el cálculo de las opciones reales, incluido el cálculo de la volatilidad de las mismas. En una segunda parte, se estudia el yacimiento aurífero de Corcoesto, para el cual se realiza la simulación del plan de negocio según las características necesarias para la explotación, donde los ingresos se modelizan mediante un movimiento geométrico browniano para simular el comportamiento del precio de la onza de oro. Se elige un desarrollo de árboles binomiales para estimar el valor futuro del proyecto, a la vez que se establece un intervalo de precios de la opción para adquirir el proyecto minero. Este intervalo estará determinado por las incertidumbres del proyecto calculadas según las metodologías de Copeland y Antikarov, y Heraht y Park. Abstract This project is aimed mainly to develop real options theory to assess a mining project start-up. The project is divided in two documents: The first document with theorical content, investments are analyzed from the clasical point of view, comparing the advantages and disadvantages of this appraisal in high uncertainity and operational flexibility conditions. Financial options are analyzed and compared to real options, in both similarities and problematics. Stochastical process that affect the project variables are also developed. Methods for estimating real options value, including the methods for volatility estimation are commented. In the second document, the Corcoesto gold deposit has been studied. A bussines plan simulation has been maked according to the characteristics of the extraction, where incomes have been simulated with a geometrical Brownian movement to estimate the gold onze behaviour. The binomial tree method has been generated to study the future project value, as well as a range of option prices, for adquiring the mine project. This interval is determined by the project uncertainity calculated with the theories from Copeland and Antikarov and Herath and Park

Las Opciones Reales en los Expedientes de Regulación de Empleo

Las empresas en situación económica negativa, recurren en España a los Expedientes de Regulación de Empleo que es la figura legal que permite ajustar sus plantillas y cuya utilización se acrecienta en épocas de crisis. El objetivo de esta investigación se focaliza en la integración de la Teoría de Opciones Reales en los proyectos organizativos de recursos humanos, en particular en el estudio y aplicación de la opción de contracción y de la opción de aplazamiento a los proyectos de desarrollo de los Expedientes de Regulación de Empleo. Las opciones reales son una herramienta de gestión, novedosa y contrastada, que posibilita realizar la valoración de los Expedientes de Regulación de Empleo tomando en consideración las incertidumbres futuras, lo que permite cuantificar mejor el resultado de la decisión y supone un avance sobre la valoración realizada de forma estática. Dos aspectos clave ha sido necesario resolver. En primer lugar determinar la fuente de incertidumbre que ponga en valor las opciones reales para este tipo de proyectos y como consecuencia desarrollar los procedimientos para obtener el valor de la opción. La puesta en valor de la opción de contracción permite, a partir de la consideración de la demanda como factor de incertidumbre, desarrollar un modelo que proporciona el valor óptimo del número de contratos de trabajo a extinguir, de modo que sitúa a la organización en la mejor posición para la toma de decisiones. La resolución del modelo se logra con la ayuda de la herramienta “The Newsvendor Model”, que facilita la obtención el valor óptimo. En la aplicación de la opción de aplazamiento se ha concluido asimismo, que la volatilidad de la demanda es la fuente de incertidumbre que hace viable la opción y a partir de dicha incertidumbre se ha desarrollado un procedimiento basado en el árbol binomial que permite obtener su valor. Una vez desarrollados los dos modelos para las opciones de contracción y aplazamiento, se ha elaborado un modelo conjunto con ambas opciones, integrando los resultados obtenidos en cada caso. Para validar los modelos obtenidos se presenta su aplicación al caso real de una empresa en situación económica negativa que requiere la necesidad de llevar a cabo un Expediente de Regulación de Empleo, lo que ha permitido comprobar la utilidad de dichos desarrollos, al obtener resultados que facilitan la toma de decisiones y que presentan soluciones que pueden ser más equilibradas para los trabajadores de la empresa, aspecto clave a tener en cuenta, dado el coste personal, familiar y social de este tipo de proyectos. La integración de las opciones reales en la gestión de recursos humanos tiene un amplio campo de aplicación, dadas las diferentes inversiones que se pueden llevar a cabo sobre el capital humano. Aunque esta investigación se ha focalizado en la opcionalidad de las inversiones para el ajuste de plantilla, existen otro tipo de inversiones en recursos humanos, como son las dedicadas a formación, motivación, adecuación o incorporación de personal, que también estarán sujetas a opcionalidad si existen incertidumbres a futuro. Con el objetivo de avanzar en el estudio y aplicación de las opciones reales a estas inversiones, se presenta un marco conceptual que identifica las bases de partida en lo referente a los retornos de las inversiones y las incertidumbres futuras. Con los resultados obtenidos en esta investigación se entiende que se ha conseguido el objetivo de aplicar la Teoría de Opciones Reales a los Expedientes de Regulación de Empleo y con ello establecer la posibilidad de mejorar las implicaciones sociales de estos proyectos dentro de la empresa y en la sociedad. ABSTRACT During crisis times, like the one Spain has been going through on the last years, the Collective Dismissal Procedure is an important issue to be considered within companies that are having a negative economic situation. This research focuses on the integration of the Real Options Theory for organizational projects in the management of human resources, and particularly the study and inclusion of the option to contract and the deferral option in Collective Dismissal Procedures. The Real Options Theory, an innovative management tool that has been proven as correct, help to improve the assessment of the Collective Dismissal Procedures using the dynamic demand instead of the static demand, giving a better quantification of the decision that is going to be taken. Two main issues which are hoped to be resolve are examined: the search for a source of uncertainty to make the real options viable for this type of projects, and consequently the development of a procedure to obtain the value of the option. The option to contract allows, from the consideration of the demand as a factor of uncertainty, to develop a model obtaining the optimal value in the reduction of the workforce, therefore allowing the organization to place itself in the best position for the decision making. The resolution of this model is achieved with the help of "The Newsvendor Model" tool, which facilitates obtaining the optimal value. The analysis performed in the deferral option also concluded that the volatility of demand is the source of the uncertainty that makes the option viable and the procedure developed by the binomial tree is the tool that enables the value of the option to be found. Once developed two models for contraction and deferment options, a joint model has been developed including both options by integrating the results obtained in each case. To validate the models, the real case of a company in negative economic situation requiring the need to carry out a procedure for collective redundancies is applied. This has demonstrated the usefulness of this kind of development that can deliver results to improve the decision making and provide more balanced solutions for company employees, key consideration given the impact on personal, family life and social environment of these Collective Dismissal Procedures. The integration of real options in the management of human resources has broad scope, given the different investments that can be performed on the human capital. Although this research has focused on the optionality of investments for downsizing, there are other investments in human resources for training, motivation, arrangement or incorporation of staff that are also subject to optionality if there are future uncertainties. With the aim of advancing the study and application of real options to these investments, a conceptual framework is presented that identifies the basis of research in terms of the investment returns and future uncertainties. With the results obtained on this research it is clearly defined the objectives for which this work was started for, the application of the Real Options Theory to the Collective Dismissal Procedure. And thereby achieve the final goal of improving the social impact of these projects within a company and society.

The deferral option in the collective dismissal procedure. La opción de aplazamiento en los expedientes de regulación de empleo.

The work in this paper focuses on the integration of the real options theory for organizational projects in the management of Human Resources, and particularly on the inclusion of the deferral option in collective dismissal procedures. This option has been studied and developed to be applied to ?Expediente de regulación de empleo?, which is the legal form existing in Spain for the collective termination of employment contracts and which organizations turn to when confronted with a negative financial situation, as a way of maintaining their viability. Two main issues which it is hoped to resolve are examined: the search for a source of uncertainty to make the deferral option viable for this type of projects, and the development of a procedure to obtain the value of the option and therefore facilitate decision making. The analysis performed has enabled us to state that the volatility of demand is the source of uncertainty that makes the option viable. The procedure developed by the binomial tree, which is determined by the evolution of demand, is the tool that enables the value of the option to be found.

Essays of strategic alliance portfolio configuration—Its performance properties, strategic antecedents and consequential effects on multinational firms' continuing foreign expansion

This dissertation focused on an increasingly prevalent phenomenon in today's global business environment—strategic alliance portfolio. Building on resource-based view, resource dependency theory and real options theory, this dissertation adopted a multi-dimensional perspective to examine the performance implications, strategic antecedents of alliance portfolio configuration, and its strategic effects on firms' decision-making on their continuing foreign expansion. The dissertation consisted of three interrelated essays, each of which dealt with a specific research question. In the first essay I applied a two-dimensional construct that embraces both alliance relations' and alliance partners' attributes to illustrate alliance portfolio configuration. Based on this framework, a longitudinal study was conducted attempting to explore the performance properties of alliance portfolio configuration. The results revealed that alliance diversity and partner diversity have different relative contributions to firms' economic performance. The relationship between alliance portfolio configuration and firm performance was shaped by degree of multinationality in a curvilinear pattern. The second essay attempted to identify the firm level driving forces of alliance portfolio configuration and how these forces interacting with firms' internationalization influence firms' strategic choices on alliance portfolio configuration. The empirical results indicated that past alliance experience, slack resource and firms' brand images are three critical determinants shaping alliance portfolios, but those shaping relationships are conditioned by firms' multinationality. The third essay primarily employed real options theory to build a conceptual framework, revealing how country-, alliance portfolio-, firm-, and industry level factors and their interactions influence firms' strategic decision-making on post-entry continuing expansion in foreign markets. The two empirical studies were resided in global hospitality and travel industries and use panel data to test the relevant theoretical models. Overall, the dissertation advanced and enriched the theoretical domain of alliance portfolio. It particularly shed valuable insights on three fundamental questions in the domain of alliance portfolio research, namely "if and how alliance portfolios contribute to firms' economic performance"; "what determines the appearance of alliance portfolios”; and "how alliance portfolios affect firms' strategic decision-making". This dissertation also extended the international business and strategic management research on service multinationals' foreign expansion and performance.

Fuzzy real option analysis in patent related decision making and patent valuation

The shift towards a knowledge-based economy has inevitably prompted the evolution of patent exploitation. Nowadays, patent is more than just a prevention tool for a company to block its competitors from developing rival technologies, but lies at the very heart of its strategy for value creation and is therefore strategically exploited for economic pro t and competitive advantage. Along with the evolution of patent exploitation, the demand for reliable and systematic patent valuation has also reached an unprecedented level. However, most of the quantitative approaches in use to assess patent could arguably fall into four categories and they are based solely on the conventional discounted cash flow analysis, whose usability and reliability in the context of patent valuation are greatly limited by five practical issues: the market illiquidity, the poor data availability, discriminatory cash-flow estimations, and its incapability to account for changing risk and managerial flexibility. This dissertation attempts to overcome these impeding barriers by rationalizing the use of two techniques, namely fuzzy set theory (aiming at the first three issues) and real option analysis (aiming at the last two). It commences with an investigation into the nature of the uncertainties inherent in patent cash flow estimation and claims that two levels of uncertainties must be properly accounted for. Further investigation reveals that both levels of uncertainties fall under the categorization of subjective uncertainty, which differs from objective uncertainty originating from inherent randomness in that uncertainties labelled as subjective are highly related to the behavioural aspects of decision making and are usually witnessed whenever human judgement, evaluation or reasoning is crucial to the system under consideration and there exists a lack of complete knowledge on its variables. Having clarified their nature, the application of fuzzy set theory in modelling patent-related uncertain quantities is effortlessly justified. The application of real option analysis to patent valuation is prompted by the fact that both patent application process and the subsequent patent exploitation (or commercialization) are subject to a wide range of decisions at multiple successive stages. In other words, both patent applicants and patentees are faced with a large variety of courses of action as to how their patent applications and granted patents can be managed. Since they have the right to run their projects actively, this flexibility has value and thus must be properly accounted for. Accordingly, an explicit identification of the types of managerial flexibility inherent in patent-related decision making problems and in patent valuation, and a discussion on how they could be interpreted in terms of real options are provided in this dissertation. Additionally, the use of the proposed techniques in practical applications is demonstrated by three fuzzy real option analysis based models. In particular, the pay-of method and the extended fuzzy Black-Scholes model are employed to investigate the profitability of a patent application project for a new process for the preparation of a gypsum-fibre composite and to justify the subsequent patent commercialization decision, respectively; a fuzzy binomial model is designed to reveal the economic potential of a patent licensing opportunity.
