Labour mobility refers to the ease with which workers can move between jobs either geographically or occupationally. Geographical mobility involves moving between jobs in different locations, while occupational mobility is moving between different jobs within an industry. Higher labour mobility leads to a convergence of wages across markets as workers move from low wage to high wage areas. However, in reality complete wage convergence does not occur due to barriers like a lack of information about other labour markets or difficulties transferring human capital between occupations.
