  1. Given the current residency matching algorithm, a program can know that an applicant did not list it first, which is consistent with a conditional match rate anomaly in the data.
  2. For the stable improvement problem with partial order priorities, (i) if the model is standard other than that, then for any (student-)optimal stable matching that Pareto dominates an initial stable matching, there is an extension of the original priority profile with which the DA returns the optimal matching, and (ii) within the class of intra-type weak but inter-type partial order priorities satisfying some monotonicity, a counterexample of the sufficiency of the condition for non-existence of a stable improvement proposed by Erdil and Kumano (2019, JET) is provided, while another condition is found to be not only sufficient but also polynomial time.

• A reserch on the nursary school matching systems

  We consider the system of the nursery schools by using the market design approach especially using the matching theory. There are three problems in the system of the nursery schools in Japan. First one is so-called "nursery school waiting lists problem", which is the problem that in several regions, many nursery schools are over-demanded. Second one is that many children are assigned to a nursery school, but it is inconvenient for their parent(s), for example, the school is far from their home. Third, to avoid assigning no school or an inconvenient school, parent(s) will various strategic behaviors that are often very costly for them.
  We disucss several matching mechanisms to solve these problems.
