VCG Mechanism (Vickrey-Clarke-Groves)
Overview
VCG allocates slots to maximize total social welfare and charges each winner the externality they impose on others. Truthful bidding is a dominant strategy. Runs in O(N log N + K × N) where N=bidders, K=slots.
When to Use
Trigger conditions:
- Designing an incentive-compatible (truthful) multi-slot auction
- Computing welfare-maximizing allocations with externality pricing
- Academic analysis comparing VCG to GSP auctions
When NOT to use:
- When revenue maximization matters more than truthfulness (GSP often generates more revenue)
- For single-item auctions (standard Vickrey suffices)
