Public risk management policies for dairy producers have the potential to induce expan-sion in milk supplies, which might lower farm-level prices and offset risk-reduction benefits. An evaluation of USDA's Livestock Gross Margin-Dairy (LGM-Dairy) insur-ance program finds economic downside risk significantly reduced, with potential to induce modest supply expansion (0 to 3 percent) if widely adopted. Supply impacts are likely limited due to relatively low participation levels and a minimal ("inelastic") supply response to risk. LGM-Dairy is more flexible and convenient than other risk management tools, such as hedging directly in futures or options markets, especially for small farms.
