A unitary model is estimated on micro data simulated by means of a collective model calibrated on GSOEP data. We investigate the effects of an introduction of linear taxation in Germany, with both the unitary and the collective model. We obtain important discrepancies in predicted labor supply adjustments, the design of tax revenue neutral reforms, and welfare implications of the reform.
