Bivariate duration data frequently arise in economics, biostatistics and other areas. In bivariate frailty models, dependence between the frailties (i.e., unobserved determinants) induces dependence between the durations. Using notions of quadrant dependence, we study restrictions that this...

Household services in France are characterized by involuntary part-timr jobd (even in permanent contracts), fixed-term contracts and multi-activity. The situation of these employees therefore does not obey a simple dual structure where permanent contracts (CDI) oppose short-term contracts. This...

This study examines individual- and state-level factors that are associated with individuals’ decisions to enter and leave the Supplemental Nutrition Assistance Program (SNAP). In particular, it examines the associations between SNAP entry and exit and (1) demographic and economic...

Using data over 1991–2008 for Switzerland, we investigate job stability through a series of Cox proportional hazards models. Our baseline results show that employment has become less stable for older male workers, with less noticeable change for other groups. However, when destination states...
