The 94th Applied Econometrics Association Conference was organized in Naples on June 1-2 2006 with the specific aim of stimulating discussion on "Policies against Unemployment". Various sessions have in particular focused on Labour Contracts, Wages and Employment. The collection of papers in this e-book, originally presented at the Conference, provides new evidence on this topic. The Guest Editors' aim was first to document two forms of employment that are characterized by more flexible labour contracts, i. e. temporary agency work and part-time jobs. The e-book then considers self-employment, whose development is also considered as a potential stepping stone from unemployment to employment. Finally, the e-book addresses the problem of legal working time as a way to plan or redistribute employment, for example in the case of a business cycle downturn.
