Does search boost efficiency?

Poaching externality, arising from job-to-job turnovers, implies that a planner should allocate fewer resources to costly job creations. However, these search efforts increase competition among employers, and this could in turn internalize the externality, whereas the congestion externality requires a unit-elastic matching function

Stable Yang-Mills connections on Special Holonomy Manifolds

We prove that energy minimizing Yang-Mills connections on a compact $G_{2}$-manifold has holonomy equal to $G_{2}$ are $G_{2}$-instantons, subject to an extra condition on the curvature. Furthermore, we show that energy minimizing connections on a compact Calabi-Yau $3$-fold has holonomy equal to $SU(3)$ subject to a similar condition are holomorphic.Comment: Final Version; will be appear in JGP. arXiv admin note: text overlap with arXiv:0808.0667 by other author
