The function of all software is to model situations that look like reality, in order to find the most viable conditions for developing a mining project, since in these what is sought is to increase revenue and reduce costs by making better decisions. In this industry investors seek to obtain the highest income in exploiting underground resources, with the aim of achieving return on investment. In this article the discount rate and the cost of rehandling of a mineral deposit hypothetical gold and copper is evaluated using the SIMSCHED DBS software. In turn a search for information, which can give clarity to the concepts with which you are working, is done. Based on the simulations performed with the two economic variables you can select the optimal net present value (NPV) for future flows. [ABSTRACT FROM AUTHOR]

Based on the general economic approaches that account natural resources, we analyze the establishment of the Principle of Sustainable Development Brundtland (PDSBrundtland) in public investment projects. Analyzing the PDS-Brundtland arise aspects of knowledge and boundaries necessary for its realization. These aspects are: a) the definition of the investment community and its evolution; b) knowledge of the communities that give value to natural resources, for which it will be necessary to have a discount rate and acceptable valuation methods; c ) establishment of the lifetimstainable Development Brundtland (PDS-Burndtland) in public investment projects. This paper discusses these aspects. It establishes a discount rate wich takes into account the development of the poorest countries, and a time rank to study these projects. Conditions are established inability to carry out these projects. Feasibility conditions are established to carry out investment projects under PDS-Brundtland. [ABSTRACT FROM AUTHOR]

This paper analyzes the different methodologies used to estimate the long-run discount rate to be used when evaluating public projects in certain countries. Additionally, it estimates, for Chile, the discount rate, based on two methodologies: one is a small variation of Gamma discounting, first proposed by Martin Weitzman (2001), and the other one uses the Ramsey formula derived from a growth model to estimate the social rate of time preference.

The cost of capital is a key input to obtain the fundamental value of an asset or project. In this paper, the cost of capital for the Chilean wine sector was estimated through the Capital Asset Pricing Model (CAPM). We briefly discuss the difficulties that arise when this equilibrium model is used in practice, and the most recent empirical literature dealing with the estimation of the systematic risk coefficient (Beta). From a sample of Chilean wine enterprises, using historical and market information, we found that the cost of capital for the wine sector activities in Chile was of 8.9% per year in real terms.

Profitability and economic efficiency indicators of apple (Malus domestica L.) cv. Gala production of a farm located in the Linares area (35°51′ S lat, 71°35′ W long), Maule Region, Chile, were estimated. Technical parameters of the orchard were obtained from historical farm records for different premises from the 1994-1995 to 2003-2004 agricultural seasons. For the valuation of the investment in the orchard and production costs, the prices for the 2003-2004 season were used. From the capital-asset-pricing model (CAPM), the weighted average cost of capital (WACC) was calculated, which was estimated at 8.71% annually. The profitability indicators calculated were net present value (VAN), internal rate of return (TIR), net present value index (IVAN) and cost benefit ratio (RBC), while the economic efficiency indicators were total mean production cost (CMET), unit margin (MU) and return on equity (RSC). The analysis was based upon one hectare. For the standard situation the results obtained were: 8,454 dollars per hectare VAN, 12.1% TIR, 0.43 IVAN, 1.51 RBC. The minimum CMET were estimated at 0.08 dollars per kilogram, the maximum MU at 0.14 dollars per kilogram and RSC up to 23.6%. The main conclusion, from an economic point of view, suggests that this activity is profitable for producers of cv. Gala apples. [ABSTRACT FROM AUTHOR]
