Aceleradoras corporativas exitosas (contexto latinoamericano) : análisis de los modelos, capacidades estratégicas y recursos claves, en una región con desafíos y complejidades propias. Un estudio de mercado emergente
(Universidad EAFIT, 2024) Gómez Jiménez, Sara; Hincapie Romero, Katherine; Betancur Álvarez, José Alejandro
This research intends to explore the corporate acceleration models of leading companies in Latin America. The study of these cases seeks to increase readers' understanding of the strategy, approach and strategic capabilities that are making these corporate accelerators successful and sustainable amid Latin American market particularities. This business research was developed under a qualitative research framework, using semi-structured interviews and secondary information such as documents, presentations, and reports of the analyzed companies. The study was divided into four fundamental phases in the research process and had a scope in the Latin American region, taking Mexico, Brazil, Chile, and Colombia as reference countries. The main results of this analysis present a general characterization of the accelerators analyzed and make an exhaustive review of their way of working with special emphasis on their main unique differentials. It is expected that these results will contribute to those corporations that want to implement their acceleration model, and also to those companies that already have an acceleration model implemented and want to reference it in order to find possible opportunities for improvement. In addition, this document contributes to knowledge generation for future research and the development of a new methodology to improve the quality of corporate acceleration models.

Aplicación de opciones reales a inversiones en proyectos de reforestación
(Universidad EAFIT, 2019) Gutiérrez Olivares, Nicolás; Parra Gutiérrez, Simón; Pareja Vasseur, Julian Alberto
This study evaluates the different valuation methodologies for reforestation projects focused on wood production for industrial use. The differences between the traditional discounted cash flow methods and the real options methods are analyzed. In addition to this, the different ways of assessing real options and their application to the final evaluation of a project are investigated. The different methods are applied in a real example of a reforestation project in order to analyze the advantages, disadvantages and quantitative differences of one method over the other. Finally, a valuation model that adapts to different types of reforestation projects is concluded and designed.
APV y CCF: el pronóstico de los ingresos y el valor de las empresas
(Universidad EAFIT, 2017) De Vivero Pérez, Héctor José; Correa Lafaurie, Luisa Fernanda
In the present paper a model for valuing companies under conditions of risk and uncertainty from the revenues is structured -- The forecast of the revenues is one of the most important elements in the result of the assessment of any business -- Based on the existing approaches for discount cash flows, specifically of the Adjusted Present Value (APV) and the Capital Cash Flow (CCF), a valuation model expressing the cash flows as a function of future revenues is formulated -- The tax shield is also linked to revenues through measures of leverage or coverage, to derive a single equation that allows you to calculate the value of the company from the revenue forecast -- In the case of companies at risk for the forecast of revenues its probability distribution parameters are estimated based on historical records and appropriate regression analysis -- The proposed model is validated with the evaluation of a group of gas stations

Comportamiento de la inversión extranjera en títulos de deuda pública de tasa fija ante escenarios de incertidumbre internacional: caso colombiano
(Universidad EAFIT, 2017) Chacón Enciso, Eliana Maritza; Niño López, Juan Carlos
The increase in uncertainty in the financial markets, combined with the main economic indicators, influence the decisions of the agents – Financial globalization, greater global liquidity, reduced transaction and communication costs have generated great interest on the part of the developed economies in the emerging markets in search of the greater profitability -- Foreign investment is attracted by a broad perspective of economic growth and determine the conditions that deserve to be studied -- In this research, in order to analyze the indicators and extracts that hold in the direct tenure on the holding of public debt securities (TES Class B Fixed Rate) by the foreign investment funds is estimated an econometric model that allows an approach to the variations of the latter before scenarios of global uncertainty, as the world economy is currently presented
The Cost of Uncertainty
(Universidad EAFIT, 2024-01) Posada, Carlos Esteban; Universidad EAFIT
The traditional and most common view of economists on the issue of (bad) uncertainty and its effects has been one of partial equilibrium. When the topic is approached from a macroeconomic perspective, the most frequent has been the examination of the effects of uncertainty shocks on short-term dynamics with various methods, but mainly with neoKeynesian and statistical (vector autoregressive) models. This document responds to another concern and has two objectives: 1) to reflect on this issue with some instruments of the macroeconomist´s toolbox related to a medium or long-term horizon, and 2) report a ciphering of the social cost of uncertainty in the Colombian case.
Cost-effectiveness analysis of thermotherapy versus pentavalent antimonials for the treatment of cutaneous leishmaniasis
(Blackwell Publishing, 2017-05-30) Cardona-Arias JA; López-Carvajal L; Tamayo Plata MP; Darío-Vélez I; Departamento de Humanidades; Estudios de Filosofía, Hermenéutica y Narrativas
Objective: The treatment of cutaneous leishmaniasis is toxic, has contraindications, and a high cost. The objective of this study was to estimate the cost-effectiveness of thermotherapy versus pentavalent antimonials for the treatment of cutaneous leishmaniasis. Methods: Effectiveness was the proportion of healing and safety with the adverse effects; these parameters were estimated from a controlled clinical trial and a meta-analysis. A standard costing was conducted. Average and incremental cost-effectiveness ratios were estimated. The uncertainty regarding effectiveness, safety, and costs was determined through sensitivity analyses. Results: The total costs were $66,807 with Glucantime and $14,079 with thermotherapy. The therapeutic effectiveness rates were 64.2% for thermotherapy and 85.1% for Glucantime. The average cost-effectiveness ratios ranged between $721 and $1275 for Glucantime and between $187 and $390 for thermotherapy. Based on the meta-analysis, thermotherapy may be a dominant strategy. Conclusion: The excellent cost-effectiveness ratio of thermotherapy shows the relevance of its inclusion in guidelines for the treatment. © 2017 Chinese Cochrane Center, West China Hospital of Sichuan University and John Wiley & Sons Australia, Ltd

(Universidad EAFIT, 2008-09-15) Ramírez Gómez, Mauricio Andrés
This paper will present the theoretical elements proposed by Coase (1937,1960,1994) and Williamson (1981,1991); remarking their analytical contributions in the field of Corporative Strategy. Additionally, this work identifies its possible conceptual and methodological limitations.
Costos de transacción y creación de empresas: Una revisión de literatura
(Universidad EAFIT, 2008-10-15) Ramírez Gómez, Mauricio Andrés
This article seeks to develop a theoretical comparison between the micro and macroanalytical approaches of Institutional Economics, keeping focus on the application of transaction costs that are commonly used in the studies on enterprise creation. In order to do this, the article reviews the works of Coase (1937, 1960, 1994), Williamson (1981, 1991) and North (1990, 1993), contrasting their analytical proposals on some articles published on that issue in order to find out if it would be useful to apply the cost transaction theory to the enterprise creation studies.

Reduce environmental imprecision since early stages of the design process with the application of fuzzy logic in order to measure impacts according to environmental inputs -- The fuzzy logic has been useful to compare products with the same material; otherwise, it can’t be compared -- Therefore, it will be meaningful to suit the tool to multicomponent product variables -- The aim was to obtain environmental impact estimates since the beginning of the design process to avoid evaluations of environmental impact until the materialization stage -- This will avoid iterative steps within the design process with a low environmental impact scope
Estimación del índice de aversión al riesgo mediante un diseño experimental utilizando la función CRRA
(Universidad EAFIT, 2016) Baena Agudelo, Julio Aníbal; Pareja Vasseur, Julián
Las decisiones de los individuos en condiciones de incertidumbre y riesgo pueden ser medidas utilizando la teoría de la Utilidad Esperada, elemento fundamental que permite encontrar de manera experimental el coeficiente de aversión al riesgo utilizando la función de Aversión Relativa al Riesgo Constante (CRRA) -- Para la estimación, se propone la metodología de Random Lottery Pairs (RLP), en la cual un sujeto se enfrenta a la elección entre un par de loterías debiendo escoger la de su preferencia -- Esta metodología se aplicó a pequeña escala con fines comparativos a estudios previamente realizados, puesto que se ha evidenciado su efectividad para medir la aversión al riesgo y su practicidad para los participantes del experimento; el cual fue aplicado a dos grupos de estudiantes de especialización y pregrado en Finanzas de la Universidad EAFIT, de las sedes Bogotá y Medellín -- Lo anterior, permitió estimar el coeficiente de aversión al riesgo mediante la calibración de la función CRRA y modelar las preferencias de los individuos, donde los resultados encontrados indican lo evidenciado en la literatura, los individuos, en este caso, representado por los dos grupos de estudiantes son aversos al riesgo
Evaluación financiera de proyecto de comercialización internacional de aguacate a través de la aplicación de opciones reales
(2019) Restrepo Sarmiento, Mateo; Pareja Vasseur, Julián Alberto
The objective of this work is to identify the impacts in terms of value when evaluating projects where management's flexibility or decision making is present. For this purpose, the evaluation of an industrial project, dedicated to Hass avocado processing, using traditional methods of valuation with NVP criteria was defined as a methodology. Then binomial trees were built to evaluate the real options of expansion, abandonment and choice complementing the initial assessment. The results indicate that both methods complement each other and that the presence of flexibility and reaction to changes in uncertainty variables represent a portion of additional value in the evaluation of projects. The motivation of the work lies in demonstrating how the concepts of value can be limited by assuming the passivity of the project managers and how strategic factors are ignored.

Impacto sobre la TRM del cambio gubernamental en Colombia, ocurrido en 2022, observado después de un año, a la luz de un valor justo
(Universidad EAFIT, 2024) Restrepo Orrego, Marco Antonio; Cadavid Gil, Alejandro
This study explores the impact of Colombia's 2022 governmental shift on the exchange rate, using techniques like PCA, VaR, and econometric models. Results indicate the Colombian peso is undervalued in Forex markets, especially against countries with leftist governments. The observed market value surpasses its fair value, suggesting a potential narrowing gap towards stability. These insights are crucial for financial leaders, Forex investors, and policymakers in their decision-making processes.
Implementación de las opciones reales en proyectos inmobiliarios
(Universidad EAFIT, 2017) Hernández Cermeño, Elkin; Támara Ayús, Armando Lenin
The current economic conditions of the country and the moderate growth of the real estate market have generated an environment of uncertainty in the financial evaluation of real estate projects since the very stage of structuring, which has led important project promoters to give up interesting real estate initiatives -- At the same time, it is impossible to deny that the changing conditions of the real estate market affect a project during its execution, forcing investors to incorporate a flexibility component when evaluating their projects financially -- This paper aims to expose the real options methodology as a novel tool that allows real estate investors to manage risk and uncertainty through the implementation of the flexibility component in the financial evaluation of projects
