The purpose of this study is to critically review consumer knowledge in marketing and propose a future research agenda. Despite the many works that have examined this variable, given its strong influence on behaviour, it has generally been studied in association with other constructs, and no studies have focused on it in a specific way. Its definition, measurement and approaches to its role and usefulness are superficial and underdeveloped. After structuring and analysing the existing literature, the authors establish, (I) which aspects are of little use to the discipline, and (II) which research lines have the most potential and should be developed and studied in greater depth, to advance and complete the existing consumer knowledge framework.

A search was undertaken for documents in the main databases in which the term “consumer knowledge” appears in a marketing or consumer context, and a critical and reflexive approach was taken to analyse the main contributions and to structure them by content blocks.

Five main content blocks were identified. A set of research gaps were detected, mainly related to the lax conceptualisation of the topic, measurement problems and the scarcity of more useful works connected with business management, and several research lines are proposed that complement the existing framework to make it more complete and operational.

This paper offers a critical review and proposes a research agenda for one of the most used but little studied variables in the field of marketing, which may help academics and professionals in the discipline to continue developing useful theories and models.

El objetivo de este trabajo es revisar críticamente el conocimiento del consumidor en marketing y proponer una agenda de investigación futura. A pesar de los numerosos trabajos que han examinado esta variable, dada su fuerte influencia en el comportamiento, generalmente se ha estudiado en asociación con otros constructos, y ningún estudio se ha centrado en ella de manera específica. Su definición, medición y aproximaciones sobre su papel y utilidad son superficiales y poco desarrollados. Después de estructurar y analizar la literatura existente, establecemos (I) qué aspectos tienen poco uso para la disciplina y (II) qué líneas de investigación tienen más potencial y deben ser desarrolladas y estudiadas con mayor profundidad; para avanzar y completar el marco existente sobre conocimiento del consumidor.

Se realizó una búsqueda de documentos en las principales bases de datos en las que aparece el término “conocimiento del consumidor” en un contexto de marketing o consumo, y se adoptó un enfoque crítico y reflexivo para analizar las principales contribuciones y estructurarlas por bloques de contenido.

Se identificaron cinco bloques principales de contenido. Se detectó un conjunto de huecos de investigación, principalmente relacionados con la laxa conceptualización del tema, problemas de medición y la escasez de trabajos más útiles conectados con la gestión empresarial; y se proponen varias líneas de investigación que complementan el marco existente para hacerlo más completo y operativo.

Este documento ofrece una revisión crítica y propone una agenda de investigación para una de las variables más utilizadas pero poco estudiadas en el campo del marketing, lo que puede ayudar a académicos y profesionales en la disciplina a continuar desarrollando teorías y modelos útiles.

Microenterprises (MEs) are vital to the growth and prosperity of economies around the world. All levels of society, from universities to national governments, have collaborated to improve the chances of survival and future growth of these businesses. The threat to life is serious, and unless concerted action is taken, the situation will spiral out of control. Policymakers and business leaders must work together to address the sustainability crisis. The study, therefore, set out to determine how various entrepreneurial skills (such as creativity, collaboration, networking, and risk-taking) affect the long-term viability of MEs. The overall objective of the study was to determine the importance of innovative problem-solving, collaboration, networking, and willingness to take calculated risks of microentrepreneurs for the long-term success of their businesses. A total of 274 microentrepreneurs in rural areas of the Ancash region of Peru were surveyed in the grocery, hardware, clothing, and food service sectors. The survival of the MEs was tested on four dimensions: innovation, leadership, networking, and risk-taking. According to the results, MEs managers can increase their longevity by cultivating creative skills, strengthening leadership as a key to business sustainability and survival, maximizing the use of networks to gain a market advantage and expand their customer base, and employing calculated risk-taking.

Integrated vehicle health management has been developed for several years in different industries, to be able to provide the required inputs to determine the optimal maintenance operations depending on the actual health status of the system. The purpose of this paper is to demonstrate the potential of a physics-based model (PbM) for prognostics with a real case study, based on the detection of incipient faults and estimate the remaining useful life of a planetary transmission of an aircraft system.

Most of the research in the area of health assessment algorithms has been focused on data-driven approaches that are not based on the knowledge of the physics of the system, while PbM approaches rely on the understanding of the system and the degradation mechanisms. A physics-based modelling approach to represent metal-metal contact and fatigue in the gears of the planetary transmission of an aircraft system is applied.

Both the failure mode caused by metal-metal contact as caused by fatigue in the gears is described. Furthermore, the real-time application that retrieves the results from the simulations to assess the health of the system is described. Finally the decision making that can be executed during flight in the aircraft is incorporated.

The paper proposes an innovative prognostics health management system that assesses two important failure modes of the planetary transmission that regulates the speed of the generators of an aircraft. The results from the models have been integrated in an application that emulates a real system in the aircraft and computes the remaining useful life in real time.

To summarize the shocks and stresses that peasants in Mexico have been subjected to since the 1940s and to examine the responses of sons of peasants working as semi-informal beach vendors in Cabo San Lucas as to what they define as the worst problems of the peasantry in their hometowns.

This chapter offers an analysis of the responses of 32 sons of peasants interviewed on Medano Beach in Cabo San Lucas in October of 2012 partially as concerns whether they would like to be peasants themselves and as to what they define as the worst problems of the peasantry in their hometowns.

Twenty-five of the thirty-two vendors interviewed would be happy to be peasants. According to all of the vendors, the overwhelming problems facing the peasantry were primarily droughts or floods (related to climate change) and lack of government aid (related to neoliberalization).

The peasantry in Mexico is being and has been marginalized both by a number of stresses and shocks, currently identified by some of those at risk as factors related to climate change and neoliberalization.

This chapter discusses the creation of the Pacific Alliance comprising four countries: Mexico, Chile, Peru, and Colombia. It shows that is not only a free trade agreement between these countries but also a multidimensional regional integration with political, economic, and cultural perspectives. Programs and actions have been structured in a way that allows and promotes integral growth of Latin American citizens. For this reason, it is important to analyze in this chapter the opportunities that Alliance Pacific generates with respect to each of these three aspects. (1) Political and diplomatic implications like eliminating visa requirements for the members, sharing some embassies, facilitating labor mobility between these countries, and proposing the creation of a joint parliament. (2) Economic and trade implications with a gradual elimination of tariffs that will allow companies to be more competitive, creation of different government agencies in each country to support business and promote intra-regional trade of goods and services, and create a joint platform to promote innovation, entrepreneurship and gender equity. Finally, (3) Cultural and educational implications, as the creation of “Student and Academic Mobility Platform” of the Pacific Alliance with scholarships for students and researchers, the integration of a “Technical Education Group” to foster integration and social inclusion of children and adolescents, and the creation of “Sports Diplomacy Program” and a “Scientific Research Network on Climate Change.” Although there are still several challenges for improvement in the Pacific Alliance, it is an agreement that will bring stability, welfare, and development effects for the members of these countries.

Purpose: This chapter analyzes the policies of immigration control implemented in Mexico in 2014 to deter the migration of Central Americans to the United States, and their impact on Central American youth migrants.

Methods: This chapter draws from three pools of data: (1) participant observation and interviews conducted with minor migrants in Mexico from 2015 to 2019; (2) Mexican and US government data on detentions and deportations of Central American minor migrants; and (3) publicly available information on Mexican and Guatemalan government programs and media campaigns targeted at addressing the migration of Central American minor migrants.

Findings: This chapter posits that the policies of migrant detention and deportation implemented in Mexico in 2014 turned the entire country into a borderland for Central Americans. These policies expanded the areas of migrant surveillance, detention, and deportation beyond Mexico’s traditional border regions, which, in turn, made youth migrants’ journeys through Mexico more precarious and prone to violence.

Research implications: This chapter examines the impact of immigration and border control policies implemented in Mexico and anti-immigration propaganda on Central American youth, and it demonstrates how Mexico has been converted into an expanded US border territory in an attempt to prevent migrants from reaching the United States’ physical borderland.

Value: This chapter analyzes the impact of US-led detention and deportation policies aimed at Central American migrants throughout Mexico, rather than just in the traditional border regions. These relatively novel policies are at the forefront of immigration control and warrant special attention.
