| Outline of Final Research Achievements |
Deferred Acceptance (DA) mechanism is the most popular matching mechanism in school choice problem. In a school choice problem, given schools' priority orderings over students being publicly announced, students submit their preference rankings over schools. Under DA mechanism, submitting true preference is dominant strategy for each student. However, non-negligible numbers of students deviate from the dominant strategy in reality.
To identify the pattern of deviation from the dominant strategy, we conducted a series of laboratory experiments. We found that students follows 'skipping-down' strategy that attributes a higher rank to schools that give those students higher priority.
Then, we derived a certain condition that the skipping-down strategy is rational in the sense that it constitutes Nash equilibrium and that the resulting matching under skipping-down strategy is stable.
