主讲人简介:
Samuele Bibi is a Macro-Development and Geopolitical Economy professor whose pluralist research analyzes financial, monetary, and structural dynamics in developing and emerging economies. He focuses on macroeconomic and monetary policies, cross-border capital flows, trade and production structures, and the hierarchy of the international monetary and financial systems, with emphasis on development finance, external vulnerability, and structural change. His work draws on Post Keynesian theory and Latin American Structuralism and engages with international political economy and economic geography.
He has published in leading journals such as the Cambridge Journal of Economics,Development and Change, and the Review of International Political Economy. He has presented at institutions including the Central Bank of Peru, the Peruvian Ministry of Economics and Finance, the Central Bank of Kazakhstan, and UNCTAD, and is a member of the Post Keynesian Economic Society, the International Initiative for the Promotion of Political Economy, and the Reteaching Economics Network.
摘要:
Since the WWII and throughout the 20th century, the significance of the US dollar (USD) has grown substantially within the international transaction framework. Most nations have relied on the US dollar for purchasing or selling oil, other commodities, products and services on the international market. The use of the USD supported and forged an economic and geopolitical function for the emitting country, the United States of America. The geopolitical implications and risks related to the USD hegemonic power in trade and financial transactions have become increasingly more striking, especially in recent decades and years. The sanctions imposed on Venezuela, Iran and more recently on Russia via the US dollar-dominated SWIFT payment system highlighted the potential threat posed by the USD hegemonic power in the global monetary system. However, in the new millennium, alternative digital currencies have begun to exert influence and have implicitly and explicitly posed a threat to that hegemony. Our paper explores the geopolitical implications of USD use on the international stage and examines the potential opportunities and threats posed by these new digital currencies, both Bitcoin and other cryptocurrencies such as the emergence of several multi-currency Central Bank Digital Currencies (CBDCs).

主讲人简介:
Xiaoxi Zhao is an Associate Economist at the RAND Corporation and a Professor of Policy Analysis at the RAND School of Public Policy. Her research primarily lies at the intersection of health economics and industrial organization, with an emphasis on the implications of vertical integration and ownership structures for physician behavior, patient outcomes, and healthcare spending. She also investigates market responses to major policy interventions, including Medicare payment reforms. Her work has been published in the American Economic Review (forthcoming), American Economic Journal: Economic Policy, Journal of Public Economics, and Journal of Health Economics, and has been presented at federal agencies including the Federal Trade Commission and the Congressional Budget Office. She received her Ph.D. in Economics from Boston University in 2021.
摘要:
Principal-agent problems often extend beyond what can be directly addressed through conventional incentive arrangements. We examine a context where physicians are likely under-incentivized to minimize total medical costs until their private financial interests align with those of patients. Leveraging novel data on physician ownership of ambulatory surgery centers—i.e., same-day facilities—we show that these equity holdings cause a substitution away from higher cost, rival settings that lowers Medicare spending by 10-40% per physician. We find no clear evidence of perverse behavior following these investments. Instead, our findings demonstrate how entrepreneurial activity can indirectly limit principal-agent problems and improve efficiency.

摘要:
在“人类世”的地质时代背景下,全球气候变化、快速城市化以及频发的自然灾害正在从根本上挑战传统城市规划与自然资源管理的基础。长期以来,主导学术界与实践界的范式建立在牛顿力学与新古典经济学的“稳态均衡”假设之上,即认为生态与社会系统围绕单一的稳定点波动,规划的目标是通过工程手段维持现状或在干扰后迅速恢复原状。然而,面对日益增加的“深层不确定性”和非线性扰动,这一机械论范式显现出极大的脆弱性与不适应性。
本讲座旨在构建一个新的理论与实践框架,即从机械的“稳态均衡”转向有机的“适应性韧性”。基于复杂适应系统理论,重构了生态规划的本体论基础,指出城市并非通过简单的指令控制运行的机器,而是由无数主体自组织涌现的复杂生命体。在方法论层面,引入扩展的“经济理性”,通过GEP、ROA及Resilience Dividend等工具,解决生态效益的外部性与跨期价值评估难题。
通过对国际上动态适应性的深度实证案例分析,论证了适应性范式在应对复杂系统演化时的优越性,并提出了融合空间技术、绿色金融创新与包容性社会治理的实施路径。
