  In this paper, I develop an integrated approach to collective models and
matching models of the marriage market. In the collective framework, both
household formation and the intra-household allocation of bargaining power are
taken as given. This is no longer the case in the present contribution, where
both are endogenous to the determination of equilibrium on the marriage market.
I characterize a class of "proper" collective models which can be embedded into
a general matching framework with imperfectly transferable utility. In such
models, the bargaining sets are parametrized by an analytical device called
distance function, which plays a key role both for writing down the usual
stability conditions and for estimation. In general, however, distance
functions are not known in closed-form. I provide an efficient method for
computing distance functions, that works even with the most complex collective
models. Finally, I provide a fully-fledged application using PSID data. I
identify the sharing rule and its distribution and study the evolution of the
sharing rule and housework time sharing in the United States since 1969. In a
counterfactual experiment, I simulate the impact of closing the gender wage
gap.
