La colusión es perjudicial para los consumidores ya que implica una cooperación ilegal para aumentar ganancias a sus expensas. En un mercado bajo colusión, las empresas participantes incrementan los precios del mercado y reducen la variabilidad de estos. Esta investigación realiza un estudio retrospectivo de una colusión determinada por Indecopi, la autoridad de competencia, en el mercado retail de GNV en Lima Metropolitana entre 2011 y 2015. Utilizando una herramienta de screening “coeficiente de variabilidad de precios” se proponen criterios de riesgo según el comportamiento de precios promedios del mercado y su desviación estándar. Se obtiene que el coeficiente es 59% mayor en los periodos colusorios respecto a los periodos de competencia. Finalmente, se realiza un monitoreo del mercado retail de GNV entre 2016 y 2021 cuyos resultados indican que existe un bajo riesgo de l...

The present study aimed to determine the concentrations of As, Cd, Pb and Hg in soil and crops (banana and cassava) in areas abandoned by gold mining, southeast of the Peruvian Amazon. The concentration and bioaccumulation of heavy metals was analyzed, according to the plant organ (root, stem, leaf and fruit). Soil Hg concentrations (< 0.01 mg/kg) were found to be similar in contaminated and uncontaminated plantations; while the concentrations of As, Cd and Pb were higher in the contaminated ones. The concentrations of As, Pb and Cd in cassava and banana were higher in the contaminated plantations. In cassava, a high accumulation of Pb and As was found in the roots and stems (> 2.9 mg/kg). In banana fruits, the lowest concentrations of all the metals analyzed were found (< 0.01 mg/kg). The degree of bioaccumulation of As and Pb was intense for cassava in contaminated areas. The ...
