Introduction to CES SI in Honour of Prof. Oleh Havrylyshyn

Our colleague and friend Prof. Oleh Havrylyshyn passed away in his Ottawa home on September 20, 2020. To honour his work and life, the Association for Comparative Economic Studies (ACES) and the Centre for Comparative Economics (now renamed as the Centre for New Economic Transitions) at SSEES University College London (UCL), with the support of Natalia Havrylyshyn, organised a conference focusing on some of Oleh's core areas of interest. The conference which was held at UCL on Monday 20th and Tuesday 21st of June 2022 included two keynote talks, and a special tribute session, which allowed friends and colleagues to reminisce about their experiences of working with Oleh, benefiting from his mentoring, feedback and friendship. This special issue includes a selection of papers that were submitted to our open call for submission. Some of these papers were presented at the conference in June 2022, others were submitted only for publication in this special issue. Finally, we would like to express our appreciation to Nauro Campos, editor of Comparative Economic Studies, for making this issue possible. Here, we first pay tribute to Oleh's career and contributions, second, recount some aspects of the conference held in his honour and finally introduce the papers included in this issue.
