ATE Research Network








Welcome to the 2nd ATE Symposium!


The Applied and Theoretical Economics (ATE) Research Network is an Asia-Pacific network centering around New Zealand and Australia aimed at fostering applied microeconomic theory with significant real-world relevance and implications, built on solid foundations from economic theory. ATE connects Trans-Tasman scholars to other researchers from Europe, North and South America, and Asia.

ATE's activities include, but are not limited to, generating opportunities for further interaction and exchange among its members, for attracting visitors, for engaging in joint research supervision, for organising workshops and guest lectures, with the goal of facilitating the advancement and dissemination of findings from research in applied microeconomic theory.

This year’s Symposium, hosted by the UNSW Business School, continues along the tradition initiated within the ATE network of bringing together scholars, policy-makers and practitioners in the fields of Antitrust Economics and Competition Policy.
