This paper presents the literature review of studies published in 2004-2014 (Web 2.0 period) in the area of consumer online trust. Based on the content analysis of 138 papers, this study highlights three major research themes: (1) trust models, (2) technological, and (3) social factors impacting online trust. It also explores topics in each major theme found in direct studies of online consumer trust. Since this literature review uses the concept-centric approach, it points out not only the major trends in research but also three understudied areas: (1) green trust, (2) trust recovery, and (3) the role of ethics in developing online trust.

Neste trabalho apresenta-se uma perspectiva sobre o elemento interpessoal do serviço em que a colaboração econômica e social é realizada em tempo real: o encontro de serviço. Visto como um local de conflito de poder e controle social, no qual as identidades são ancoradas e significados coletivos são constituídos e reproduzidos. O referencial teórico deste trabalho baseia-se na Teoria da Atividade (TA), que permite compreender melhor o encontro de serviços como um locus político de tensão contraditório entre fornecedores e clientes (internos e externos) no mercado de Ensino Superior (ES).

We present a perspective on the interpersonal element of service in which economic and social collaboration takes place in real time: the service encounter. We view it as a site of conflict for power and control where social identities are anchored and collective meanings are constituted and reproduced. Our theoretical underpinning is taken from the Activity Theory (AT) to shed light on the service encounter as a contradictory, political locus of tension between providers and customers (internal and external) in the Higher Education (HE) market.
