  Aims. In this work, we aim to make a differential comparison of the
neutron-capture and p-process element molybdenum (Mo) in the stellar
populations in the local disk(s) and the bulge, focusing on minimising possible
systematic effects in the analysis. Methods. The stellar sample consists of 45
bulge and 291 local disk K-giants, observed with high-resolution optical
spectra. The abundances are determined by fitting synthetic spectra using the
SME-code. The disk sample is separated into thin- and thick-disk components
using a combination of abundances and kinematics. The cosmic origin of Mo is
investigated and discussed by comparing with previous published abundances of
Mo and the neutron-capture elements cerium (Ce) and europium (Eu). Results. We
determine reliable Mo abundances for 35 bulge and 282 disk giants with a
typical uncertainty of [Mo/Fe]~0.2 and ~0.1 dex for the bulge and disk,
respectively. Conclusions. We find that the bulge possibly is enhanced in
[Mo/Fe] compared to the thick disk, which we do not observe in either [Ce/Fe]
nor [Eu/Fe]. This might suggest a higher past star-formation rate in the bulge,
however, since we do not observe the bulge to be enhanced in [Eu/Fe], the
origin of the molybdenum enhancement is yet to be constrained. Although, the
scatter is large, we may be observing evidence of the p-process contributing to
the heavy element production in the chemical evolution of the bulge.
