The impact of the Russia-Ukraine War on the U.S. Economy
The Russia-Ukraine war, which began in February 2022, has significantly impacted the global economic landscape, with profound effects on the United States economy. This paper provides a comprehensive analysis of these impacts [3]. The study highlights how the conflict has disrupted supply chains, escalated inflation, and influenced U.S. monetary and fiscal policies. Key findings indicate that higher energy and food prices have accelerated inflation, leading the Federal Reserve to increase interest rates and implement quantitative tightening measures [12]. Concurrently, the U.S. government has responded with substantial fiscal measures, including increased defence spending, energy sector support, and economic aid packages [17]. The paper also discusses the broader implications of the war on global trade, supply chains, and geopolitical alliances. By examining the interplay between these factors, the study provides insights into the policy measures needed to mitigate the adverse effects of the conflict and enhance economic resilience. The findings underscore the importance of adaptive strategies and international cooperation in navigating the complex economic challenges posed by the Russia-Ukraine war.

Abstract In many real-world reinforcement learning (RL) problems, besides optimizing the main objective function, an agent must concurrently avoid violating a number of constraints.In particular, besides optimizing performance, it is crucial to guar- antee the safety of an agent during training as well as deployment (e.g., a robot should avoid taking actions - exploratory or not - which irrevocably harm its hard- ware).To incorporate safety in RL, we derive algorithms under the framework of constrained Markov decision processes (CMDPs), an extension of the standard Markov decision processes (MDPs) augmented with constraints on expected cu- mulative costs.Our approach hinges on a novel Lyapunov method.We define and present a method for constructing Lyapunov functions, which provide an ef- fective way to guarantee the global safety of a behavior policy during training via a set of local linear constraints.Leveraging these theoretical underpinnings, we show how to use the Lyapunov approach to systematically transform dynamic programming (DP) and RL algorithms into their safe counterparts.To illustrate their effectiveness, we evaluate these algorithms in several CMDP planning and decision-making tasks on a safety benchmark domain.Our results show that our proposed method significantly outperforms existing baselines in balancing con- straint satisfaction and performance.
