| Outline of Annual Research Achievements |
1. I have been polishing the paper "Horizontal Merger Analysis with Endogenous Product Range Choice" with my coauthor, making more extensions and further discussion.
2. I have been working on strategic inattention and endogenous market structures, examining how firms' strategic choices on attention or inattention impact the quantity setting and the market outcome. The completed works have been submitted to refereed journals.
3. My paper "Horizontal Merger Analysis with Endogenous Product Range Choice" was presented in the Asia-Pacific Industrial Organisation Conference, 2022.12, Melbourne, Australia. It was also presented in the workshop at Keio University in May, 2023.
