Temporary Programs, Lasting Questions: Ad Hoc Assistance in the U.S. Farm Safety Net

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Large ad hoc assistance programs have returned to U.S. farm policy since 2017, operating alongside a more developed safety net built around federally subsidized crop insurance, Title I commodity programs, and standing disaster assistance. This paper reviews the renewed use of ad hoc assistance, documents its recent scale using USDA data, and ...

Practical long-distance quantum key distribution system using decoy levels [PDF]

, 2009
Quantum key distribution (QKD) has the potential for widespread real-world applications, but no secure long-distance experiment has demonstrated the truly practical operation needed to move QKD from the laboratory to the real world due largely to ...

Ex‐Ante Assessment of Farm Resilience to Institutional Shocks: A Modeling Approach

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Using the agent‐based model SWISSland, we simulate farm‐level responses and interactions under two institutional shocks: tariff reductions and direct payment reductions. Using a framework we developed, we assess resilience capacities, resilience attributes, and the provision of private and public goods, following the shock.
