Ítem Análisis económico de las subastas y algunas experiencias de su aplicación en adjudicación de licencias de telefonía móvil(Universidad EAFIT, 15/10/2004) Tamayo Plata, Mery Patricia; Posada Montoya, Carlos Enrique; Universidad EAFIT; Empresas Publicas de Medellín E.S.P.EÍtem Comprehensive economic evaluation of thermotherapy for the treatment of cutaneous leishmaniasis in Colombia(Universidad EAFIT, 2018-01-15) Cardona-Arias, Jaiberth Antonio; López Carvajal, Liliana; Tamayo Plata, Mery Patricia; jaiberthcardona@gmail.co; lililopez14@gmail.com; mptamayo@eafit.edu.co; cBackground: Cutaneous leishmaniasis causes a high disease burden in Colombia, and available treatments present systemic toxicity, low patient compliance, contraindications, and high costs. Objective: To estimate the cost-effectiveness of thermotherapy versus Glucantime in patients with cutaneous leishmaniasis in Colombia. Methods: Cost-effectiveness study from an institutional perspective in 8,133 incident cases. Data on therapeutic efficacy and safety were included, calculating standard costs; the outcomes were disability adjusted life years (DALYs) and the number of patients cured. The information sources were the Colombian Public Health Surveillance System, disease burden studies, and one meta-analysis of controlled clinical trials. Incremental cost-effectiveness was determined, and uncertainty was evaluated with tornado diagrams and Monte Carlo simulations. Results: Thermotherapy would generate costs of US$ 501,621; the handling of adverse effects, US$ 29,224; and therapeutic failures, US$ 300,053. For Glucantime, these costs would be US$ 2,731,276, US$ 58,254, and US$ 406,298, respectively. With thermotherapy, the cost would be US$ 2,062 per DALY averted and US$ 69 per patient cured; with Glucantime, the cost would be US$ 4,241 per DALY averted and US$ 85 per patient cured. In Monte Carlo simulations, thermotherapy was the dominant strategy for DALYs averted in 67.9% of cases and highly cost-effective for patients cured in 72%. Conclusion: In Colombia, thermotherapy can be included as a cost-effective strategy for the management of cutaneous leishmaniasis. Its incorporation into clinical practice guidelines could represent savings of approximately US$ 10,488 per DALY averted and costs of US$ 116 per additional patient cured, compared to the use of Glucantime. These findings show the relevance of the incorporation of this treatment in our country and others with similar parasitological, clinical, and epidemiological patterns.Ítem Cost-effectiveness analysis of thermotherapy versus pentavalent antimonials for the treatment of cutaneous leishmaniasis(Universidad EAFIT, 2018-02-01) Cardona-Arias, Jaiberth Antonio; López Carvajal, Liliana; Tamayo Plata, Mery Patricia; Veléz, Iván Darío; jaiberthcardona@gmail.co; lililopez14@gmail.com; mptamayo@eafit.edu.co; idvelez@pecet-colombia.orgIntroduction: The treatment of cutaneous leishmaniasis is toxic, has contraindications and a high cost. Objective: 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 were 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 $1,275 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.Ítem Descripción del funcionamiento del sector eléctrico colombiano(Universidad EAFIT, 02/04/2006) Alvarez Sierra, Santiago; Tamayo Plata, Mery Patricia; Universidad EAFITÍtem Obstacles to innovation and external sourcing of knowledge: Evidence for German and Spanish firms(Universidad EAFIT, 2018-05-16) Gómez, Estefanía; Elena, Huergo; Tamayo Plata, Mery Patricia; mptamayo@eafit.edu.co; egomezv@eafit.edu.co; ehuergo@ccee.ucm.esThe goal of this research is to empirically study the relationship between obstacles perceived by companies to carrying out their innovation activities and their decisions about external sourcing of knowledge through the outsourcing of R&D or technological cooperation. Using information on German and Spanish companies from the year 2010, we obtain that in both countries this association is positive, and that companies that assign greater importance to factors that impede their innovation activities are also more likely to engage in external sourcing of knowledge. This relationship seems to be especially strong in companies that do not engage in internal R&D activities or do so sporadically, while it is much weaker in companies that perform internal R&D continuously. Nonetheless, the importance that companies assign to the market power of established companies as a barrier to innovation is positively associated with technological cooperation especially in continuous R&D performers.Ítem The Offshoring Phenomenon(Universidad EAFIT, 2014) Tamayo Plata, Mery Patricia; Universidad Eafit,Escuela de Economía y Finanzas, Medellín, Antioquia, Colombia; Escuela de Economía y Finanzas; Economía; Estudios en Economía y Empresa
