This two volume collection covers important developments in the theory and empirical analysis of training since the start of the 1990s. It includes the seminal articles on training theory in the context of imperfect markets, which are essential for understanding social interventions in the private market. New analyses of the determinants of training are presented, some incorporating wider perspectives from industrial relations and human resource management. Advances in the methodology for evaluating public training programmes are then covered, with examples of both experimental and non-experimental methods. Finally, the volumes include major studies of the impact of training on workers and organisations, with examples from several different countries.
