Matching efficiency is a concept related to functioning of the labor market. Poor matching means that both open vacancies and unemployed people exist simultaneously at the same travel-to-work area. Are you familiar with related theories, methodologies or tools? I am grateful, if you could hint how to approach research topics and applications related to this phenomenon or other fields in which matching efficiency concepts or similar frameworks are applied.
