FROM NICHE TO MAINSTREAM TRANSITIONS: DIGITAL SECOND-HAND MARKETS FOR MILLENNIALS.

This paper addresses the issue of over-consumption among millennials by repositioning reacquisition of consumer goods and digital platforms that support peer-to-peer exchange. We use transition design to frame our thinking and provide the focus on local communities and global technologies. To understand millennials, we have used in-depth interviews as the main method. The analysis of the interview data led to the recognition of five significant barriers for the uptake of second-hand platforms. Synthesis of findings, together with consumer behavior archetypes that we have identified previously, led to nine implication for the design of future services. These are a significant step toward re-conceptualization of peer-to-peer services and building of local communities of interest based on lifestyles and interests, including being greener.
