The paper is based on informal institution analysis in accordance with the institutional economics theory. The authoress assumes that wage expectations are a kind of an informal institution. The characteristic level of these expectations can be observed among labour market participants as the unemployed and work seeking employed. The survey presented in the paper was carried out in January and June 2006 among a group inhabitants of the Wielkopolska region. The survey results enable the authoress to define how the experience gathered on the labour market influences personal wage expectations among job seekers - the unemployed and employed people.
