## 2 Literature Review
### Electronic Product Consumers in Mexico and Latin America  
In Mexico, knowledge about consumer behavior regarding electronics is quite limited. In 2009 and 2010, the National Institute of Ecology and Climate Change of Mexico (INECC) conducted a survey on EEE consumer behavior in the northern border and the metropolitan area of the valley of Mexico [49]. The survey covers social, environmental, and economic dimensions, such as the average useful lifetime of electronic devices, discarded equipment's final destination, and environmental and human health risks. This survey revealed consumers' knowledge regarding what ultimately happens to their e-waste, demonstrating that 71% of the population did not know their WEEE's final destination. Of the remaining 29%, 56% thought the waste went to a garbage dump, 15% that it was reused or went to a collection center, 13% to a sanitary landfill, and 10% to a landfill. Finally, 6% did not have any idea about WEEE's final destination.  
In Latin America, particularly in Mexico, there is a gap in the literature about consumer behavior regarding EEE. Table 1 shows the results of a search performed during Autumn 2020, using SCOPUS database, in which three keywords--\"circular economy,\" \"e-waste,\" and \"electronic waste\"--were used as part of the search string to look for them in the title, abstract, or keywords of the indexed publications. The search string was intentionally defined with a broad scope in mind knowing based on the authors' research experience that the existing literature on e-waste management, including consumer behavior, in the circular economy context is scarce. The research string gave us a total of 14,707 documents that were screened to identify those with a focus on Latin America. Only six papers out of this total were really focused on Latin America, namely, Mexico [9; 12; 17], Brazil [18; 19], and the Caribbean Islands (viz. Aruba, Barbados, Grenada, Jamaica, and Trinidad and Tobago) [20]. The rest of the studies were targeted to Europe and Asia, where circular economy strategies have been under development for several years [6; 35; 38; 50; 51].  
About Mexico, there was only one study on consumer behavior regarding WEEE and circular economy in the SCOPUS database results, which was developed by the same co-authors of this article (see reference [12]).  
Furthermore, since the unit of analysis of this research work is \"Mexico,\" a search of governmental reports developed by the Mexican Ministry of Environment and Natural Resources (SEMARNAT) for the last seven years [21; 22; 23] was conducted (see Table 2).  
This literature review shows that the available information and studies on consumer behavior regarding e-waste management in Latin America are quite limited. The value of this work, therefore, lies in the fact that it is filling this gap. This factual context provides the framework for this article and its reliance on the questionnaire that was used. We now turn to these issues.
