This work aims at providing more insight on the relationship between atypical employment and poverty, with a focus on temporary contract workers. I want to assess to which extent temporary contract workers face higher risk of poverty than standard workers and how factors such as the family structure and the welfare states influence this risk. I study the implication of being under temporary contract on the risk of poverty in a longitudinal perspective in order to investigate further the association between atypical work and poverty not only by contract type and individual characteristics as done in the two previous dynamic analysis (Debels (2008) and Amuedo-Dorantes and Serrano-Padial (2010)) but also considering the households' financial situation, the role of the partners' earnings and benefits, while controlling for feedback effects of contract type and state dependency of poverty as done by Amuedo-Dorantes and Serrano-Padial (2010). In order to do that, we use two large panels for Germany (SOEP) and UK (BHPS-UKHLS). Those panels allow us to cover extended periods as SOEP goes from 1984 to 2017 and for UK from 1991 to 2019.
