PurposeThe purpose of this paper is to examine use and sharing economy (SE) continuance intention, and the mediation effects of use between individuals' motivations and SE continuance intention. A theoretical model is developed to explain use and SE continuance intention as intrinsic and extrinsic motivated behaviour, as proposed by self-determination theory. Factors are derived from SE context and supported by published research on SE.Design/methodology/approachThe partial least squares path modelling (PLS-PM) technique is used to test the model in a quantitative study involving 256 users of SE services.FindingsFindings suggest that use and SE continuance can be explained by concurrent intrinsic and extrinsic motivations. Moreover, high environmental concerns may restrain the use of SE services. Findings show that continuance intention is influenced by current use of SE services. Moreover, the study emphasizes the mediation effect of use between intrinsic and extrinsic motivation and SE continuance intention.Research limitations/implicationsThe analysis of use behaviour should be complemented with other measures of use and with data provided by qualitative methods of research. Further research should also consider the effect of different control variables and mediation effects.Practical implicationsBrand managers and companies providing services through digital platforms should address individuals' needs in order to stimulate voluntary engagement in persistent SE practices.Social implicationsThis study informs the consumer in general so that the SE can develop its potential alongside an economy based on the ownership of private property.Originality/valueThis study extends findings on continuance intention research by offering internal motivation factors as predictors of post-adoption behaviour and emphasizes the role of use on SE continuance intention.

Purpose When evaluating a booking enquiry, hosts rely on peer-to-peer (P2P) accommodation platforms (P2PAP) to make an informed decision. Consequently, accepting or rejecting a booking is influenced by the capacity of the P2PAP to convey to hosts valuable information about guests. This study aims to explain hosts’ task performance in short-term rentals (e-rentals). Design/methodology/approach The proposed model explains hosts’ task performance in e-rentals as a combination of task-specific user capabilities and technology capabilities. The model was tested using the partial least square path modelling technique. Findings Task-specific user capabilities of covert observation and interrogation were found to have a positive influence on task performance. Moreover, a moderation effect of representation on the relationship between self-disclosure and task performance was found to be significant, yet contrary to the one hypothesized. Originality/value The findings from this study help to develop the concept of task-specific user capabilities in shaping task performance.
