- Banking Products In PortugalPublication . Couto, Gualter; Pimentel, Pedro; Toste, Luís Miguel da SilvaThe offerings of financial products to investors have evolved considerably over the last decades. This study was undertaken to understand the importance of financial products in Portugal for banks and private clients. Different financial products can provide to banks an important role on their revenues and liquidity. For clients allows to invest their savings according the risk, complexity and potential return they pretend be exposed. Financial products can be divided into four groups: deposits, investment funds, securities, and insurance banking. The six largest banks with Portuguese headquarters were identified based on an analysis of net asset value, and the products offered were analyzed. It was found that on an overall basis, the offerings of financial products available in banks are rather diverse and, at the same time, uniform. It was also noted that investment decisions are dependent on the investors and there are financial innovations that attract differentiated savings.
- Empirical analysis of the Hsia option-pricing based model cost of capitalPublication . Neves, João C.; Pimentel, PedroThe cost of capital is a fundamental concept in strategic decisions such as capital investments, capital structure, new issues, mergers and acquisitions, spin-offs and other corporate restructurings. This paper explores empirically the option-based model developed by Hsia (1991) for estimating the cost of equity and the cost of capital of the firm. The composition of the sample in this exploratory study is all 17 non-financial companies listed in the Euronext Lisbon that are included in the market index PSI20. The Hsia model is used for estimating the cost of equity and the cost of capital of the firm for these 17 companies and is compared to the estimates obtained from the Capital Asset Pricing Model (CAPM) and the traditional weighted average cost of capital (WACC). The difference between the means of the cost of equity estimated by Hsia model and CAPM is not statistically significant at 1% level and their correlation of 46.2% is statistically significant at 1% level. However, the differences at the individual level are quite large. One of the limitations found in this study was the inconsistency on the computation of the cost of debt. The problem arise from the fact that the cost of debt do not follow the pattern expected in the theory, but we also find that the Hsia model is unable to deal with potential inconsistencies of the financial market.
- Evaluation of the surrender and the minimum guaranteed rate of return options in life insurance productsPublication . Pimentel, Pedro; Pereira, RicardoThis paper aims to value a Guaranteed Investment Contract (GIC), offered by insurance companies, with a minimum rate of return and an option to surrender the contract (surrender option) at any time before the maturity date. The valuation framework uses a set of different models to value each one of these two options included on a GIC contract commercialized by a Portuguese financial group. We estimate that the surrender option value is around 1.18 percent of the net premium and that the value for the minimum guaranteed rate of return option varies between 0 an 7 percent, according to the used model.
- Forecast of hotel overnights in the autonomous region of the AzoresPublication . Santos, Carlos; Couto, Gualter; Pimentel, PedroThis paper concentrates on the application of various time series methods in order to forecast the monthly overnights in Azorean hotels. The aim is to find out the degree to which the forecast of overnights segmented by country of origin, presents smaller errors when compared with the forecast of the total overnights in the Region. The appropriate forecasting method by a tourist’s country of origin, is also analyzed so that potential optimal combinations of separate forecasts can be found in order to forecast the total overnights in Azores.
- High speed rail transport valuationPublication . Pimentel, Pedro; Azevedo-Pereira, José; Couto, GualterThe present paper investigates the optimal timing of investment for a high speed rail (HSR) project, in an uncertain environment, using a real options analysis (ROA) framework. It develops a continuous time framework with stochastic demand that allows for the determination of the optimal timing of investment and the value of the option to defer in the overall valuation of the project. The modelling approach used is based on the differential utility provided to railway users by the HSR service.
- High Speed rail transport valuation and conjuncture shocksPublication . Couto, Gualter; Nunes, Cláudia; Pimentel, PedroIn the present paper we derive the optimal investment policy of investment in the high speed rail (HSR) project, under uncertainty, using the real options analysis (ROA) framework. We assume that the HSR demand, the main source of uncertainty, follows a geometric brownian motion with random jumps, complying with abrupt change of level caused by random events. The occurrence of such events is caused by external shocks. We assess the impact of these shocks in the HSR demand threshold, along with the investment opportunity value, and the option to differ. We consider several distributions for these jumps, and we compare with the base-line case (where exogeneous jumps are not considered).
- High speed rail transport valuation and policy decisionsPublication . Pimentel, Pedro; Azevedo-Pereira, José; Couto, GualterThe present paper investigates the process of decision making regarding the optimal timing to invest in the high speed rail (HSR) project, under uncertainty, using the real options analysis (ROA) framework. It’s developed a continuous time framework that allows a solution to the problem concerning the optimal timing to invest and to value the impact of the option to defer in the overall valuation of the project, with multiple uncertainty factors. Besides considering a stochastic demand, the effect of uncertainty in the investment’s expenditure and over the benefit per user is incorporated in a model with three stochastic variables. The modelling approach used is based on the differential utility provided to railway users by the HSR service.
- Introducing random investment in high speed rail transport valuationPublication . Couto, Gualter; Nunes, Cláudia; Pimentel, PedroIn this paper, we extend Couto et al. (2012) high-speed rail (HSR) transport valuation model based on real options analysis, in order to embrace random investment. Optimal timing to invest, value of the option to defer and investment opportunity value are assessed considering uncertainty upon HSR demand and investment expenditures, both following a geometric Brownian motion with jumps driven by Poisson processes. Numerical results presented, showing the consistence with the former model and the additional uncertainty impact.
- Quality of the Azores destination in the perspective of touristsPublication . Santos, Carlos; Couto, Gualter; Pimentel, Pedro; Vieira, José CabralTourism is a growing industry in the Autonomous Region of the Azores. However, little is known about how tourists evaluate this destination, something which certainly constitutes a shortcoming if one takes into consideration that this is a very competitive industry, with new destinations appearing every year and others increasing their market share. This paper focuses on the quality of the Azores destination in the perspective of tourists and, to an extent, has the goal of contributing to reduce this shortcoming. According to our findings, 74% of the tourists interviewed consider the global quality of the Azores destination to be very good or excellent, with the landscape, the climate/weather, the hospitality, the cleanliness and the security being the most highly-rated partial indicators. Additionally, a regression analysis indicates that the evaluation of the global quality of this destination varies according to the individual characteristics of tourists.
- Real Options Valuation : an application to the portuguese real estate marketPublication . Oliveira, Carla; Couto, Gualter; Pimentel, PedroThe contribution of real options analysis on the valuation of Portuguese undeveloped building sites is significant on the decision making regarding the apartment-buildings construction. Using the options model developed by Quigg (1993), and including the necessary readjustments for the Portuguese market, it was found that the scale price elasticity parameter and construction expenditures’ elasticity of scale parameter had a strong impact on building sites’ values. The empirical analysis revealed that the option to defer adds value to undeveloped building sites’ valuations. This fact cannot be ignored when deciding upon an investment’s implementation.
