    Análisis del mercado turístico en Medellín: una aproximación desde el análisis descriptivo
    (Universidad EAFIT, 2023) Mesa García, Esteban; Jaramillo Vélez, Ricardo; Ospina Londoño, Mónica
    The tourism market in Medellín has undergone significant changes in recent years. It is possible to observe a considerable increase in tourist demand, which in turn has been accompanied by a shift in supply, as the market seeks to respond to the new characteristics of the demand. This paper provides an overview of the tourism market, evaluating variations in supply and demand based on the descriptive analysis of available data on foreign arrivals, hotel occupancy, the Airbnb market, digital nomads, employment, rental prices, and other relevant factors to understand the change in behavior of this market. We find that there has been a shock in demand post-pandemic, which results in a shift in the demand curve due to changes in tourist preferences, partly due to the devaluation of the peso, which favors the arrival of foreign tourists. As for the supply, we find that there was an increase in registrations in the National Tourism Registry in the city, the number of available beds increased, and the income from Airbnb increased significantly.

    Los efectos del saneamiento básico en el desarrollo local de las comunidades : un metaanálisis para comprender las realidades de nuestro país y territorios
    (Universidad EAFIT, 2023) Banguero Moreno, Carlos Alberto; Cantet, María Natalia
    Is there a correlation between basic sanitation and community development? A general perception is that basic sanitation is related to community development; However, there is still insufficient quantitative information to support this hypothesis and to allow considerations of the true effects of sanitation on the development of communities, so the objective of the work is to determine if there is a direct relationship between basic sanitation and community development, through a quantitative review – meta-analysis at the global level. R² determination coefficients were collected along with scale moderators, population, zone type and control type. After the review of 3003 articles, about 63 data were obtained from 15 sources. Most of them are scientific articles, with the theme occupational environmental public health and the United States being the country with the most publications. Statistical analyses determined that basic sanitation and community development are positively correlated in the world's population centers, indicating that advances or setbacks in sanitation processes such as drinking water, sewerage influence the development of communities. The great variability between studies is mainly explained by the scale (local, regional and local) which means that the level of connection between these two variables may be stronger or weaker if the evaluation changes the spatial scale. On the other hand, to materialize the positive impacts of sanitation in the municipality of Apartadó, a strategy must be generated that allows the updating of the municipal structure that responds to the new dynamics of development. In general, we can affirm that sanitation has a fundamental impact on development, since it generates an impact on environmental, economic and social aspects, and is a political challenge since it depends on the decisions and public policies that are designed in local, regional and national governments and administrations. Keywords: Sanitation, basic sanitation, drinking water, wastewater management, wastewater disposal, solid waste management, solid waste disposal.

    Importancia del uso del e-commerce para el desempeño de los micronegocios en las principales ciudades de Colombia
    (Universidad EAFIT, 2023) Gómez De Las Salas, Andrea Carolina; Cao, Qiuyi; Acosta Mejía, Camilo Andrés
    This paper analyzes the relationship between the use of E-Commerce by Colombian microbusinesses and their performance , especially in the main cities of the country. We use Data from DANE's Emicron for 2019 and 2021, which is a nationally representative survey about microbusinesses among 24 main cities in the country. This survey covers 86,969 microbusinesses for the year 2019 and 77,156 for 2021, which is equivalent to 11,654,842 observations when using the sample expansion factors. The results of the estimated regressions confirm the positive correlation between the use of E-Commerce and the sales and profits of microbusinesses in Colombia. Among all the companies in our study, the use of E-Commerce is associated with higher sales and profits of the previous year on average of 19.5%.

    ¿Influye el desempeño de los gobiernos en la percepción de confianza ciudadana a nivel local? Análisis de los determinantes de la confianza en las autoridades municipales de Colombia
    (Universidad EAFIT, 2023) Betancur Rendón, Juan Camilo; Chaparro Cardona, Juan Camilo
    This paper explores the relationship between institutional performance levels and citizens’ trust perceptions towards local political authorities of 36 Colombian municipalities in 2019 and 2021. Utilizing data from the National Survey of Political Culture and municipal government performance measurements, a panel data model with random effects was implemented. The findings reveal a positive correlation between government performance and perceived levels of citizen trust in local authorities. The mobilization of domestic resources for public investment is the public administration dimension most associated with local positive trust attitudes, a potential effect of decentralization that has been scarcely studied before. The primary social drivers of institutional trust at the municipal level in Colombia are citizens’ income, occupation, and religion, consistent with findings from case studies previously conducted in other democracies.

    La influencia del capital de riesgo (venture capital) en la superación del valle de la muerte en un grupo de empresas de base tecnológica en Colombia
    (Universidad EAFIT, 2023) Celis Pérez, Alejandro; Yepes Callejas, Edgar Rene
    The valley of death can be defined as "a condition of blockage or latency experienced by innovation projects, for which progress has been made in the development of technological dimensions, but other dimensions of the business model, necessary to carry out said innovations up to the stages of new product development (DNP), operation and commercialization.” (Yepes, 2022). Within the dominant theory, the use of alternative financing mechanisms has predominated, as a response to this condition and as a strategy to get out of the valley of death. Within these alternative investment mechanisms, venture capital predominates, which can be defined as a financing instrument for high-growth companies where investors buy shares in these companies, providing financing, monitoring, experience and contacts with the industry (Kelly & Kim, 2018). This mechanism is specially designed to address the gap that exists between the demand for capital by emerging companies and the supply available by traditional private institutions and/or public institutions. The objective of this work was to examine the influence of venture capital on the financial performance of a group of companies in Colombia and its role in overcoming the valley of death. For this, the financing operations with venture capital that were carried out in Colombia were consulted in specialized databases. Subsequently, the years between 2015 and 2021 were selected as the analysis period and the financial results of the companies that received financing in those years were consulted. This work makes important contributions to the study of the valley of death, because, to date, from the review of the literature, there are no works that have been identified that have validated the occurrence of this phenomenon in technology-based companies in Colombia, as well as the influence of venture capital financing in the performance of these organizations from the financial point of view that are reflected in the overcoming, or not, of the valley of death. The most recent exercises have focused on studying R&D projects in university institutions to identify the dimensions associated with the occurrence of the Valley of Death, even before these projects have received funding.

    Revisión del estado del arte, de algunos sistemas de gestión integral de residuos sólidos en Colombia y en el mundo, para generar recomendaciones de implementación de buenas prácticas, en el municipio de Sopetrán departamento de Antioquia
    (Universidad EAFIT, 2023) Quiceno Flórez, Adrián Esteban; López Barrantes, Silvio Andrés
    The main purpose of this study is to carry out a review of the state of the art of some integrated solid waste management systems in Colombia and worldwide, in order to identify better practices from the economic, environmental and social aspects, to generate suggestions for the adoption of a waste management model in the Township of Sopetrán, Department of Antioquia. Regarding the methodological framework, this study is longitudinal research, which means an analysis of the development of solid waste management in the world and in Colombia; also, this is exploratory research to build recommendations or methodological proposals that will enable the future development of practices or models based on well-established and existing practices. This research is also descriptive because it allows us to analyze the elements and facts which have influenced globally and locally to carry out a good solid waste management, through a detailed analysis of the most outstanding projects and thus determine the most appropriate to implement in the Township of Sopetrán. Documentary research was used as the main instrument, based on primary input, reviewing the studies conducted by other researchers and cities about solid waste management, which provided us different points of view and implementations to determine the best system or alternatives to be adopted in the Township of Sopetrán. While several programs have been implemented in the Township of Sopetrán, contamination is still a problem due to the lack of adequate solid waste management. In accordance and based on the results of the study, it was concluded that the project "Feira do Lixo" of the Green Change Program of Curitiba/Brazil can be replicated, being an innovative model of how environmental management and food safety may be combined to enhance the people's quality of life. The proposal suggested to the Township of Sopetrán is an alternative that might be useful specially to help with the issue of adequate solid waste management, which will promote the town's economy and the sustainable agriculture.

    Adopción de tecnologías de Inteligencia Artificial : un estudio para las empresas en Colombia
    (Universidad EAFIT, 2023) Vera Otálvaro, Lina María; Atis Ortega, Karen Liseth
    This document provides a broad description regarding the adoption of Artificial Intelligence (AI) technologies in Colombian companies. We managed to discriminate the analysis by economic sectors using a new module presented in the Encuesta Pulso Empresarial (EPE) of the National Administrative Department of Statistics (DANE) in 2022. The module collects data from more than 8,500 companies on the adoption, reasons for use and non-use of AI technologies. During the investigation, we discovered that organizing administrative processes is one of the main issues that the implementation of AI would solve. Nonetheless, high acquisition costs and lack of experienced personnel capable of using AI makes its implementation more difficult. Through a probability model, it is evident that, among other factors, using the Internet, digital platforms, investing in software equipment, carrying out research and development activities, increase the probability of adopting AI technologies. These research adds as an innovative element a set of variables considering perceptions and expectations that companies have related to present and future economic situations and its influence on the adoption of AI technologies.

    Determinantes del mercado de vivienda de interés social. Un caso de estudio para Medellín y su Área Metropolitana
    (Universidad EAFIT, 2023) Hincapié Acosta, Juan Sebastián; García Cruz, Gustavo Adolfo; García Rendón, John Jairo
    This study estimates the effect of the subsidies given for the purchase of housing to families in the municipalities over the years, the characteristics of the public housing projects, the price per square meter offered per project and the multidimensional poverty index per block on the number of square meters offered by construction companies in public housing projects located in Medellín and its Metropolitan Area. We find evidence of the importance of housing subsidies for construction companies and how the availability of land can generate incentives for the construction of social interest projects compared to sites with low availability. The results show that for the total of the Metropolitan Area of the Aburrá Valley the delivery of subsidies for the purchase of housing has positive effects on the amount of square meters offered by construction companies, finding that a 1% increase in the subsidies delivered for the purchase of housing is related to a 0.017% increase in the square meters offered by construction companies. 017% in the square meters offered, likewise an increase of 1% in the price per meter is associated with 0.45% more square meters offered and finally it is found that the increase of one bedroom is associated with an increase of 1.57% in the square meters offered by construction companies, however, thanks to the estimation of the polynomial square of the bedrooms it is observed that there are decreasing marginal returns finding an optimal amount of between 2 and 3 bedrooms for units in the public housing projects.

    Trust and economic development : saving groups in areas affected by armed conflict in Colombia
    (Universidad EAFIT, 2022) Montoya Henao, José Alejandro; Nyssens, Marthe; Ospina, Jaime Alberto
    The access and use of financial services play a significant role in the economy. They are key to achieve of four of the United Nations’ Sustainable Development Goals. In poor countries and rural areas, financial services are mostly non-existent or hard to access. In those areas, the communities created informal institutions to partially solve the absence of services. Indigenous saving and credit systems were the first examples of informal financial rural services. Around the world these systems were used as a guide for formal methodologies of financial services, such as Rotating Savings and Credit Association –ROSCA – or Accumulating Savings and Credit Associations – ASCA –. Colombia is a country where SG could work, because it is a developing country, with more than 20% of population living in rural areas, which experienced for around 50 years an internal armed conflict that affected rural territories, displacing population to large cities, weakening social fabric, and augmenting distrust on society and institutions. Colombia’s government introduced the methodology of Saving Groups in 2008 in 30 municipalities. Since then, public projects and international cooperation initiatives, as CELI N/S implemented SG in different regions of the country impacting the territories and people’s lives. This study focuses on the formation of the groups, determining if trust is a condition or a result, and if the initial goals of the people participating in the groups are economic or social.

    Relationships between Financial Development and Income Inequality in South America between the years 2000 and 2020
    (Universidad EAFIT, 2022) Aranzazu Ramírez, Mariana; Soudant, Joey; Ballesteros Ruiz, Carlos Andrés
    This paper examines the influence of financial development on income inequality on ten South American countries between the years 2000 and 2020. This work includes the overview of relevant literature as well as the construction of a dataset, and the use of an empirical model using panel data method with a long-run approach. By evaluating the impact of different dimensions of financial development: depth, access and efficiency of financial institutions and financial markets on the level of income inequality, this paper tries to disentangle the opposing views on the relationship between finance and income distribution. The main results of the analysis indicate that first, financial development decreases income inequality. Second, the negative effect on income inequality is mainly through the financial development of institutions rather than financial markets and third, when going into deeper multidimensional analysis, two out of the three measurements of financial development: access and efficiency of financial institutions, tend lower income inequality. We also performed some robustness tests by using other measurement of income inequality, the 90-10 ratio instead of the Gini coefficient, in which we arrived at similar results. With the 90-10 ratio, financial development decreases income inequality and now not only two but the three measurements of financial development in institutions: depth, access and efficiency and the efficiency of financial development in markets have a negative relationship with income inequality. Finally, the analysis was done by country in which two out of five countries chosen (Argentina and Brazil) have a negative relationship between financial development and income inequality. The robustness analysis was also done by income level where we categorized different countries by their income level, and we looked at the effect on the depth, access, and efficiency level. We found that on the country level, the three measurement of financial development affect income inequality differently.
