A Methodological model to assist the optimization and risk management of mining investment decisions
Resumo:
Identifying, quantifying, and minimizing technical risks associated with investment decisions is a key challenge for mineral industry decision makers and investors. However, risk analysis in most bankable mine feasibility studies are based on the stochastic modelling of project “Net Present Value” (NPV)which, in most cases, fails to provide decision makers with a truly comprehensive analysis of risks associated with technical and management uncertainty and, as a result, are of little use for risk management and project optimization. This paper presents a value-chain risk management approach where project risk is evaluated for each step of the project lifecycle, from exploration to mine closure, and risk management is performed as a part of a stepwise value-added optimization process.

El presente trabajo de tesis doctoral tiene por finalidad demostrar que las decisiones de financiación y de inversión inmobiliaria en España influyen de manera determinante en la configuración del proceso urbanístico y arquitectónico. Este planteamiento inicial obliga a formular las siguientes cuestiones: - En una primera fase, la situación en España del sector inmobiliario y su relación con el sector financiero en el contexto de la actual crisis financiera, iniciada en el año 2008. - Los métodos de análisis y selección de inversiones y su aplicación a los proyectos de inversión en función de la naturaleza de los activos inmobiliarios. - La valoración inmobiliaria para determinadas entidades financieras. - Características de la gestión financiera empresarial y de las empresas inmobiliarias. - El origen de fondos para financiar el proceso urbanístico y arquitectónico mediante las instituciones de inversión colectiva inmobiliaria y el mercado inmobiliario. - La regulación actual en España, a nivel estatal, del suelo como materia prima del sector inmobiliario. - La edificación residencial y el mercado inmobiliario en el actual contexto económico. - La posibilidad de crear en España un mercado de derivados basado en activos inmobiliarios. - Cómo repercute la actividad económica, a través de la inversión y la financiación, en los activos inmobiliarios, en el urbanismo y la arquitectura. Las cuestiones precedentes se resuelven de forma sistemática y metodológica en esta tesis doctoral estructurada en tres grandes bloques (inversión, financiación y repercusiones en el urbanismo y la arquitectura), obteniendo una serie de respuestas reflejadas en el desarrollo del presente trabajo que se sintetizan en las siguientes líneas: - La actual crisis financiera iniciada en el año 2008 ha provocado en España el colapso del sector inmobiliario y una nueva concepción en la naturaleza de los activos inmobiliarios. El sector inmobiliario trae causa del sector financiero, en especial del crédito bancario. - Dependencia y vinculación del sector inmobiliario español de la política monetaria europea: la incorporación de España a la moneda única transforma por completo el sector inmobiliario español. - Los métodos de análisis y selección de inversiones se conforman como instrumentos relevantes que nos permiten jerarquizar nuestros proyectos. No obstante, presentan una serie de limitaciones y dificultades de aplicación práctica, por lo que no deben considerarse como herramientas que nos aporten una única solución irrefutable. - La valoración de activos inmobiliarios se constituye en un pilar básico que fundamenta la correcta aplicación de los fondos. - La inversión en activos inmobiliarios puede realizarse de forma directa o indirecta. En este último supuesto, con una influencia relevante de las innovaciones financieras surgidas en los últimos años. - Las instituciones de inversión colectiva y el mercado hipotecario constituyen instituciones fundamentales capaces de captar importantes cantidades de fondos que impulsan y financian el proceso urbanístico y arquitectónico. - El complejo y cambiante sistema jurídico español en materia de suelo, dificulta la implementación de los procesos urbanísticos y arquitectónicos. - Tras la crisis financiera de 2008, los activos inmobiliarios tienen un comportamiento similar a otros activos en cuanto a subidas y bajadas de precios. En el actual sistema económico, la especulación forma parte inherente a la naturaleza de los activos inmobiliarios. - Desde una perspectiva teórica, existe la posibilidad de crear un mercado de derivados que tenga como subyacente activos de naturaleza inmobiliaria. - Sin actividad económica, el proceso urbanístico y arquitectónico carecerá finalmente de sentido y tenderá a desaparecer. No obstante, son las innovaciones tecnológicas, a nivel de producto y proceso, las principales causantes del impulso de la actividad económica. - A pesar de lo expresado en los documentos urbanísticos internacionales, la transformación del urbanismo y la arquitectura dependen principalmente de la actividad económica y la tecnología. En un segundo nivel, la inversión y la financiación condicionan y definen el urbanismo y la arquitectura, incluso a nivel de proyecto si se pretende su materialización. En base al desarrollo previo, el objetivo fundamental de esta tesis doctoral ha sido demostrar que las decisiones de financiación y de inversión tienen una importancia capital y determinan la configuración de los activos inmobiliario, del urbanismo y la arquitectura, por lo que deben ser tenidas en cuenta no sólo en su materialización sino incluso en la propia concepción del proceso creativo. ABSTRACT The present dissertation aims to show that real estate financing and investment decisions in Spain play a predominant role in structuring urban development and architectural solutions. The issues addressed to support that contention include: - As a preliminary study, the situation of the real estate industry in Spain and its relationship to the financial sector in the context of the 2008 financial crisis. - The methods used to analyse and select investments and their application to investment projects, by type of real estate asset. - Appraisal of certain financial institutions’ real estate asset holdings. - Characteristics of financial institution and real estate company corporate management. - Sourcing funds for financing urban development and architecture through real estate investment trusts and the real estate market. - Present nation-wide regulations on landed property in Spain as a raw material for the real estate industry. - Residential building construction and the real estate market in the present economic context. - The possibility of creating a real estate asset-based derivatives market in Spain - The impact of economic activity, through investment and financing, on real estate assets, urban development and architecture. The aforementioned issues are addressed systematically and methodically in this dissertation, which is divided into three major units: investment, financing, and impact on urban development and architecture. The conclusions drawn are summarised below. - The financial crisis that began in 2008 has induced the collapse of the Spanish real estate industry and spawned a new perception of the nature of real estate assets. The real estate industry is dependent upon the financial sector, in particular on bank loans. - The Spanish real estate industry also depends on and is related to European monetary policy: Spain’s adherence to the single currency ushered in a thorough overhaul of its real estate industry. - Investment analysis and selection methods constitute highly suitable tools for project evaluation and ranking. Nonetheless, inasmuch as their practical implementation is subject to a series of limitations and difficulties, they should not be thought able to deliver a single irrefutable solution. - Real estate asset appraisal is a mainstay to the rightful application of funds. - Real estate asset investments can be made directly or indirectly. The latter approach is heavily influenced by the financial innovations forthcoming in recent years. - Investment trusts and the mortgage market are key institutions able to raise substantial funding, thereby driving and financing urban development and architecture. - Spain’s complex and changing legal provisions on land management are an obstacle to urban development and architecture. - Since the 2008 crisis, real estate assets have behaved much like other assets in terms of rising and falling prices. In the present economic context, speculation is indivisible from real estate assets. - Theoretically speaking, a derivatives market with real estate holdings as the underlying assets lies within the realm of possibility. - In the absence of economic activity, urban development and architecture are senseless pursuits and tend to disappear. Technological innovation in products and processes are the main drivers of economic activity. - Despite the opinion expressed in international papers on the subject, the transformation of urban development and architecture depend primarily on economic activity and technology. In a second dimension, investment and financing condition and define urban development and architecture, even at the design level for projects aspiring to actual construction. Pursuant to the foregoing, the primary aim of this dissertation is to show that financial and investment decisions are of cardinal importance and determine the structure of real estate assets, urban development and architecture. They must consequently be borne in mind not only in connection with implementation, but also with conceptual design and the creative process itself. I

The analysis of how tourists select their holiday destinations along with the factors that determine their choices is very important for promoting tourism. In particular, transportation is supposed to have influence on tourists? decissions. The objective of this paper is to investigate more especifically the role of High Speed Rail (HSR) in this choice. Two key tourist destinations in Europe, Paris and Madrid, have been chosen to understand the factors influencing this choice. On the basis of a survey conducted to tourists, we found out that some aspects such as the presence of architectural sites, the quality of promotion of the destination itself, and cultural and social events, have an impact on their choice. However the presence of the HSR system affects the choice of Paris and Madrid as a touristic destination in a different way. For Paris, TGV is considered a real transport mode alternative among tourists who use it quite often. On the other hand, Madrid is chosen by tourists irrespective of the presence of an efficient HSR network. Data collected from the two surveys have been used for a further quantitative analysis. Regression models have been specified and parameters have been calibrated to identify the factors influencing holidaymakers to revisit Paris and Madrid and visit other touristic spots accesible from HSR from these cities.

Water supply instability is one of the main risks faced by irrigation districts and farmers. Water procurement decision optimisation is essential in order to increase supply reliability and reduce costs. Water markets, such as spot purchases or water supply option contracts, can make this decision process more flexible. We analyse the potential interest in an option contract for an irrigation district that has access to several water sources. We apply a stochastic recursive mathematical programming model to simulate the water procurement decisions of an irrigation district?s board operating in a context of water supply uncertainty in south-eastern Spain. We analyse what role different option contracts could play in securing its water supply. Results suggest that the irrigation district would be willing to accept the proposed option contract in most cases subject to realistic values of the option contract financial terms. Of nine different water sources, desalination and the option contract are the main substitutes, where the use of either depends on the contract parameters. The contract premium and optioned volume are the variables that have a greater impact on the irrigation district?s decisions. Key words: Segura Basin, stochastic recursive programming, water markets, water supply option contract, water supply risk.
