张斌：需求不足的危害、原因与治疗︱重阳荐文

Core Viewpoint - Insufficient demand is a significant challenge faced by countries with advanced production capacity and income levels, leading to various economic issues such as declining corporate revenues, reduced employment opportunities, and worsening social wealth [5][10][12]. Summary by Sections Demand Insufficiency - Demand insufficiency is described as a "disease of wealth," primarily affecting countries with high production capacity and income levels, while lower-income countries typically face supply shortages and inflation [5][28]. - The dangers of demand insufficiency are severe, potentially leading to acute economic collapse and long-term resource wastage if not addressed [5][12][19]. Understanding Demand Insufficiency - Understanding demand insufficiency requires analyzing four levels: economic development stage, triggers, market failures, and inadequate policy responses [26][28]. - Market failure is emphasized as a critical aspect in understanding demand insufficiency, influencing the choice of appropriate policy responses [5][10][19]. Policy Responses - Effective policy responses to demand insufficiency must meet three criteria: they must be external to market logic, target fast variables, and facilitate broad credit growth [40][41]. - Counter-cyclical monetary and fiscal policies are recognized as standard and effective remedies for demand insufficiency, although they often face public skepticism [6][41]. Historical Context - Historical examples of prolonged demand insufficiency include the Great Depression in the 1920s and Japan's "lost two decades" from 1992 to 2012, both characterized by persistent economic challenges due to insufficient demand [10][11][12]. Economic Impact - The impact of demand insufficiency includes significant declines in corporate income and profitability, leading to increased bankruptcies and reduced investment [13][14]. - The overall wealth of society diminishes, with falling corporate profits resulting in lower asset valuations and real estate prices [14][15]. Broader Consequences - Demand insufficiency also leads to a deteriorating business environment, increased external trade disputes, worsening income distribution, and heightened financial risks [18][19]. - The phenomenon can create a self-reinforcing negative cycle, where reduced spending leads to lower incomes and further decreases in demand [32][33]. Conclusion - Addressing demand insufficiency requires a comprehensive understanding of its complexities and the implementation of targeted, effective policies that can break the cycle of decline [38][39].
