This volume contains 12 thoroughly refereed and revised papers detailing recent advances in
research on designing trading agents and mechanisms for agent-mediated e-commerce. They were
originally presented at three events: the Workshop on Agent-Mediated Electronic Commerce (AMEC
2013) co-located with AAMAS 2013 in Saint Paul MN USA in May 2013 the Workshop on Trading
Agent Design and Analysis (TADA 2013) co-located with AAAI 2013 in Bellevue WA USA in July
2013 and the Joint Workshop on Trading Agent Design and Analysis (TADA 2014) and
Agent-Mediated Electronic Commerce (AMEC 2014) co-located with AAMAS 2014 in Paris France in
May 2014. Given the breadth of research topics in this field the range of topics addressed in
these papers is correspondingly broad. These include the study of theoretical issues related to
the design of interaction protocols and marketplaces the design and analysis of automated
trading strategies used by individual agents and the deployment of such strategies in times
as part of an entry to the trading agent competition.
