    Empirical studies of competition in the Chilean electricity market
    (2013) Varas Valenzuela, Pablo I.; Rudnick Van de Wyngard, Henry; Pontificia Universidad Católica de Chile. Escuela de Ingeniería
    La competencia dentro de un determinado mercado es una condición deseable, dado que asegura la correcta asignación de recursos económicos y la existencia de precios que maximizan el bienestar social económico. El objetivo de la presente tesis es brindar evidencia empírica respecto de los niveles de competencia y existencia de poder de mercado en el sector eléctrico chileno. A la fecha los estudios que se han realizado han sido en base a simulaciones, y no en base a información de transacciones del mismo mercado. A través de modelos econométricos se estudian los márgenes de los precios de energía de contratos de los clientes libres, con respecto al costo de desarrollo del sistema. En primer lugar se analiza el impacto de la crisis del gas argentino en los niveles de competencia, y luego se compara la intensidad de competencia de los generadores respecto de los contratos de clientes libres y de los procesos de licitación de las distribuidoras.

    Latin America Goes Electric: The Growing Social Challenges of Hydroelectric Development
    (IEEE, 2013) Varas Valenzuela, Pablo I.; TironiRodó, Manuel; Rudnick van de Wyngard, Hugh; Rodríguez, N.
    Hydroelectricity was, for many years, one of the main ways to meet the new electricity needs of Latin American countries. This is evidenced by the presence of some of the larger plants worldwide and the high hydroelectric participation in all electricity matrices (Figure 1). Faced with growing prospects for future economic development, an underlying concern is how to respond to the important and growing demands for electricity. In several countries, governments and electric companies have opted to continue with the construction of hydropower plants, especially large-scale ones, as the main means of meeting this challenge. However, major projects formulated in recent years have been put in check by various difficulties, some even stopped. Despite the different political, regulatory, and economic conditions that exist in Latin America, there are common elements in the difficulties faced by these projects. While in the past, large-scale hydroelectricity was the successful response to higher electricity consumption, societies have changed, and this technology faces new cultural, social, and political conditions.
