This book constitutes revised selected papers from the 17th and 18th International Workshop on
Agent-Mediated Electronic Commerce AMEC TADA 2015 and 2016 which took place in Istanbul
Turkey in May 2015 and in New York City USA in July 2016. The 10 papers presented in this
volume were carefully reviewed and selected for inclusion in the book. Both workshops aim to
present a cross-section of the state of the art in automated electronic markets and encourage
theoretical and empirical work that deals with both the individual agent level as well as the
system level. Given the breadth of research topics in this field the range of topics addressed
in these papers is correspondingly broad. They range from papers that study theoretical issues
related to the design of interaction protocols and marketplaces to the design and analysis of
automated trading strategies used by individual agents - which are often developed as part of
an entry to one of the tracks of the Trading Agents Competition.
