The article argues that the Federal Reserve's recent rate hike decision, while justifiable on inflation grounds, highlights a critical lack of an underlying, transparent policy framework. The core problem is that the Fed's decisions appear discretionary, leading to market uncertainty because the committee's judgment, rather than clear data, dictates policy shifts. The author proposes that the Fed adopt a formal monetary policy rule—an algebraic formula linking the target rate to indicators like inflation and unemployment—to replace subjective guidance. Implementing such a rule would provide market predictability, enhance transparency, and shield the Fed from political attacks by making deviations from the standard easily quantifiable.
Decisive Economic Advantage: Modeling the Transition from Temporary First-Mover Leads to Economic Dominance in Artificial General Intelligence
English Summary
This RAND report introduces the concept of Decisive Economic Advantage (DEA), a state where early leads in Artificial General Intelligence (AGI) become permanent dominance through self-reinforcing feedback loops between technological capability, economic deployment, and capital reinvestment. Using a dynamic economic model and Monte Carlo simulations, the author identifies two primary pathways to dominance: 'frontier-driven' intelligence explosions and 'accumulation-driven' reinvestment moats that can occur even without recursive self-improvement. The findings suggest that strategic intervention leverage decays rapidly as asymmetries widen, implying that policymakers must prioritize early detection of regime shifts and tailor responses—such as export controls or ecosystem containment—to the specific growth mechanism involved.
中文摘要
這份蘭德公司 (RAND) 的報告提出了「決定性經濟優勢」(Decisive Economic Advantage, DEA) 的概念，這是一種透過技術能力、經濟部署與資本再投資之間的自我強化回饋循環，使通用人工智慧 (AGI) 的早期領先地位演變為永久主導權的狀態。作者利用動態經濟模型與蒙地卡羅模擬，識別出達成主導權的兩條主要路徑：即使在沒有遞迴式自我完善的情況下也可能發生的「前沿驅動型」智慧爆炸，以及「累積驅動型」的再投資護城河。研究結果表明，隨著不對稱性的擴大，策略性干預的槓桿作用會迅速衰減，這意味著決策者必須優先考慮及早偵測模式切換，並針對所涉及的特定增長機制量身定制應對措施，例如出口管制或生態系統遏制。

The ongoing Ebola outbreak in the DRC serves as a critical warning that the global health security system is fundamentally unprepared for future biological threats. The difficulty in containing this outbreak is compounded by the rising risk of emerging pathogens and the growing potential for AI misuse in bioweapon development. Policy must therefore shift from reactive, crisis-driven funding to sustained, proactive investment in resilient public health infrastructure, particularly in conflict zones. Addressing this requires strengthening global surveillance, ensuring consistent international cooperation, and mitigating the intersection of conflict, climate change, and disease spread.

3.A Design Lab Pilot to Inform Strategies for Expanding Access to Medications for Opioid Use Disorder in Community Mental Health Centers (RAND)
Despite MOUD being the standard of care for opioid use disorder, access remains severely limited in Community Mental Health Centers (CMHCs), which serve the primary population with co-occurring disorders. A Design Lab pilot identified payment limitations and regulatory complexity as the chief barriers to implementation. The most feasible and high-impact strategy identified was establishing a structured learning exchange between CMHC leaders and insurers to improve reimbursement understanding. Policymakers and payers are therefore advised to pilot this learning exchange model to initiate broader payment reform and expand evidence-based care for this vulnerable population.

The article argues that modern conflicts are increasingly defined by attrition, driven by three strategic gaps: the difference between nominal military power and usable capacity; the difficulty of achieving breakthroughs in a technologically advanced battlefield; and the detachment of military means from clear political objectives. Evidence from Ukraine and the Middle East demonstrates that sustained logistics, rapid technological adaptation, and proxy networks are now more decisive than sheer military size. For policymakers, this implies a strategic shift away from seeking short, decisive victories toward preparing for prolonged, high-cost engagements, requiring a focus on sustainable supply chains and defining concrete, attainable political end-states.

Congress has significantly expanded presidential tariff authority by passing the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026, allowing the executive to impose up to 100% tariffs on key buyers of Russian energy and sanctions enablers. The article argues that this legislation represents a dangerous abdication of Congress's Article I authority, as it grants the executive vast, discretionary power without specifying criteria for enforcement. Historically, the executive could claim tariffs were its own doing; however, by writing and passing this new authority, Congress now owns the resulting trade policy and its economic consequences. This shift implies that future tariffs will be viewed by the public as a direct legislative action, potentially undermining the administration's credibility and creating political vulnerability.
