Proposition 12 Increased Consumer Costs in U.S. Pork Markets

Using retail and wholesale data from 2020 to 2026, this study evaluates how Proposition 12 affected pork prices, market segmentation, and consumer costs. The results show that compliant pork remains a small share of the market but commands higher prices, with retail price increases nearly three times larger than wholesale premiums. Overall, the policy led to higher consumer costs, exceeding $400 million, while reducing pork purchases in affected states.

Fertilizer Price Projections Under Strait of Hormuz Disruption Scenarios

This study evaluates how disruptions in the Strait of Hormuz affect fertilizer prices and agricultural costs using a global fertilizer market model and 25 years of trade data. The results show that fertilizer prices could rise sharply across all scenarios, with urea reaching up to $996 per ton and remaining elevated through 2027. Despite lower prices than in 2022, affordability worsens due to lower crop prices, increasing cost pressure on farmers and reducing demand.

Routine Actuarial Adjustments Cut Taxpayer Cost in Subsidized Agricultural Insurance

Routine adjustments to crop insurance rating parameters can significantly reduce taxpayer costs while maintaining program effectiveness. The results show that updating all ratemaking parameters reduces taxpayer expenditure by roughly 10% annually, while updating reference yields alone can generate savings of up to 15%. However, gains are uneven across states, highlighting ongoing challenges in achieving actuarially sound and fiscally efficient pricing.
