The different situations confronting young labor market entrants in different European countries may be described in terms of the following models: (1) the conditions of labor market entry are basically tied to the nature of the qualification acquired in initial training, experience accumulated in the labor market plays a very secondary role, and labor market entrants tend to be rapidly integrated into the work situations of more experienced work with the same qualification profile; (2) labor market entrants' working conditions are very different from those of more experienced workers, and initial training plays a lesser role in the transition process; and (3) labor market entrants have greater access to jobs and occupational mobility than in the first two models, and acquired experience and qualifications obtained in initial training are each involved in hiring but are partly interchangeable from companies' viewpoints. Denmark is representative of the first model; Italy is representative of the second, and France and the United Kingdom are representative of the third. These models are subject to change in response to factors such as the following: long-term economic prosperity combined with low demographic growth; the spread of new information and communication technologies; and changes in existing systems of work relations.
