For this analysis we used panel data estimation, choosing as measures of profitability the financial indicators of operating margin, gross margin, ROE and ROA as the dependent variable, including the Markup of costs as an independent variable and choosing the size classification according to their incomes level for the unobserved heterogeneity. We conclude that the impact over the cost is controlled for the companies through their expected profit margins, being that an indirect impact on the gross and operating profit and a direct impact on ROE and ROA returnsÍtem El papel de las opciones reales en la valoración de una mina de cobre(Universidad EAFIT, 2019) Restrepo Giraldo, Santiago; Quiroz Mora, Alonso Elías; Tamara Ayus, Armanado LeninThe mining sector is characterized by the existence of projects that have operational and administrative flexibility, due to the high volatility of external factors that affect the development of these projects. The appropriate methodology for evaluating this type of project is the real options since it includes the value of the flexibility in the final value of the project. In the valuation of the copper mining project, the binomial tree method is used to analyzed and valued the option of temporary closure of the mine in five periods. The result of the valuation shows that when assessing the project by this method, the value of the project in the zero period increased 10.12% with respect to the calculation made by the net present value methodology, showing the importance of valuing through real options to maximize the total value of mining projects.Ítem Recuperación de cobre a partir de los residuos de tarjetas de circuitos integrados de aparatos eléctricos y electrónicos(Universidad EAFIT, 2017) Vargas Muñoz, Mariana; Tirado Gallego, Luis Fernando; Gutiérrez Monsalve, Jaime AndrésÍtem Riesgo de pérdida de activo por hurto en la red de cobre de una empresa de telecomunicaciones.
