Abstract
The production of jets is studied in collisions of virtual photons, $\gamma^*\mathrm{p}$ and $\gamma^*\gamma^*$, specifically for applications at HERA and LEP2. Photon flux factors are convoluted with matrix elements involving either direct or resolved photons and, for the latter, with parton distributions of the photon. Special emphasis is put on the range of uncertainty in the modeling of the resolved component. The resulting model is compared with existing data.
