In this paper, we study the relationship between the merit order effect and the ownership structure of renewable resources in electricity markets. We use daily frequency data from the Colombian electricity market in 2012-2019 and designed a strategy to estimate the spot price's dependence on renewable energy. We study how the participation of multi-technology firms in renewable energy alters the spot price. Our main results show a merit order effect for the Colombian electricity market, but this weakens in the presence of greater participation of multi-technology firms in the total availability of renewable energy for the day.
This study analyzes the pass-through of wholesale costs to retail prices for unregulated users in the Colombian electricity market, using monthly data from 2012 to 2019. This period encompasses moments with and without an El Niño phenomenon. We use an empirical model to analyze the pass-through heterogeneity according to the characteristics of users and firms, showing that the pass-through is incomplete, differs according to the presence of El Niño, and is heterogeneous. The pass-through was greater from September 2015 to May 2016 because an El Niño caused hydrological resource scarcity and several critical thermal plants halted operations. In other words, the pass-through tends to be more comprehensive during an El Niño event. Additionally, the pass-through differs between firms with a high concentration of the market and the remaining firms and between urban and non-urban users.
Higher education provides students with the knowledge and skills necessary for professional development. These are applied when students make the transition from the academic world to the world of work and allow them to generate value for organizations. This study analyzes the impact that hard and soft skills have on the performance of undergraduate students in their internships. The methodology uses multiple regression techniques on data from 2010 to 2021 from a sample of 6632 students in 25 undergraduate programs at Icesi University in Colombia. The results confirm the importance of both soft and hard skills and show that soft skills explain students’ performance to a greater extent. These findings can assist universities, faculty and organizations in developing the skills necessary for students to improve their performance, build successful careers and generate value for organizations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
