第四节 确定性谬误：复杂演化系统与线性机械论的冲突
共产主义理论的另一个重大认识论缺陷，在于其采用了过时的线性机械论世界观，来理解本质上属于复杂非线性演化系统的人类社会。
一、还原论与机械唯物主义的局限
19世纪的物理学盛行“还原论”与“拉普拉斯决定论”。拉普拉斯曾断言：如果有一个智者（即所谓的“拉普拉斯妖”）知道某一时刻宇宙中所有粒子的位置和动量，他就能够利用牛顿力学公式计算出宇宙过去和未来任意时刻的状态。
共产主义的历史观深受这种机械决定论的影响。它试图将复杂的社会变迁，简化为“生产力发展-生产关系变革 ”的单向线性因果链条。它相信只要控制了生产资料公有制这个“总开关”，就能按预期产出完美无瑕的共产主义社会。
然而，现代科学（尤其是系统论、混沌理论与复杂性科学）已经深刻揭示：由海量相互作用的自主个体构成的社会系统，是一个典型的“非线性复杂适应系统”。
二、涌现性与不可预测性
在复杂系统中，整体的属性并非各部分属性的简单线性叠加，而是通过个体之间纷繁复杂的局部相互作用“涌现出来的。例如，语言不是由某个古代语言学家坐在书房里一次性设计出来的，而是无数人在几千年交流中自发演化出来的；货币不是由某个国王发明的，而是交易双方为了降低交易成本在长期实践中自发挑选出来的市场媒介。
复杂系统具有以下几个根本特征，直接宣告了共产主义宏大规划的破产：
涌现性不可预先计算：你无法通过研究单个分子的属性来预判龙卷风的轨迹；同理，中央计划部门也绝不可能通过分析单个工人的生产率，来预判整个社会市场需求的动态演化。
蝴蝶效应与敏感的初始条件：社会系统中存在大量的正负反馈回路，微小的扰动可能引发巨大的连锁反应。行政部门下达的一个微小指令（例如调整某种农产品的收购价），可能会在几年后引发全局性的农业崩溃与饥荒。
个体的适应性行为：人不是棋盘上任由摆布的棋子（正如亚当·斯密在《道德情操论》中所批判的“棋盘棋子谬误”）。当国家出台一项计划政策时，社会上的每一个个体都会根据这项政策调整自己的行为策略（如搞地下黑市、消极怠工、偷工减料）。这种自下而上的“反向适应”，会迅速冲垮自上而下的政策初衷。
三、试错机制的阻断与试错成本的无限放大
人类文明的进步，本质上是一个自下而上的“试错与演化”过程。在自由社会与市场经济中：
每天都有成千上万的企业家在尝试新的技术、新的商业模式、新的组织形态。
绝大多数尝试都会失败（企业倒闭），但这种失败的成本被限制在局部（由投资人与企业承担）。
极少数成功的尝试会被市场筛选出来，被全社会模仿和推广，从而推动整个文明向前演进。
这是一个极其高效的“演化算法”。
然而，共产主义的中央计划体制阻断了这种自下而上的试错机制。由于公有制消灭了私人资本与独立创业的可能，所有的创新和决策都必须经过中央计划部门的审批。这导致了两个致命的认识论困境：
创新的窒息：任何突破传统框架的创新想法，在面对官僚体制的层层审批时，都会因为不符合既有的“五年计划”而被扼杀在摇篮里。官僚体制天生偏好守成与标准化，排斥不确定性。
错误的全局化与灾难化：在市场中，一个企业老板决策失误，顶多导致一家公司破产；但在中央计划体制下，由于决策权高度集中于顶层，一旦中央规划者犯错，这个错误就会被行政机器无限放大到整个国家。例如，中国“大跃进”时期的密植与深翻农业政策，或者苏联对李森科“伪遗传学”的行政强制推广，都给整个国家带来了毁灭性的灾难。
本章小结：认识论破产的必然逻辑
综上所述，共产主义之所以终究无法实现，其根本原因不在于道德建设不够完善，也不在于具体执行者的能力高低，而在于其核心理论框架建立在一座认识论的沙丘之上。
共产主义假设：
人类能够彻底掌握历史演进的客观规律（历史决定论谬误）；中央机构能够收集并处理全社会所有的经济与社会信息（全知规划者幻觉）；复杂的社会知识可以被完全统计化和集中化，而忽略了决定社会运转的分散知识与隐性知识（哈耶克知识问题）；人类社会可以像一部机械一样被自上而下精密设计，而否定了社会作为复杂系统的自发演化属性（机械论谬误）。
当一种政治与经济理论在认识论层面违背了信息传播的物理规律、人类理性的边界以及复杂系统的演化逻辑时，它在现实中的崩溃就不是一个“是否”的问题，而仅仅是一个“何时”的问题。
放弃“全知理性”的狂妄，承认人类知识的局限性与社会的不可彻底设计性，是人类走向理性与成熟的必经之路。也唯有在此认识论基础之上，倡导分权、保护私有产权、尊重自发秩序与自由选择的社会制度，才能真正为人类的繁荣与尊严提供永续的保障。
第二章 经济学的不可能三角：产权、价格与激励机制
在第一章中，我们从认识论的视角剖析了共产主义如何陷入“全知理性”的狂妄，并阐明了中央计划体制在信息收集与处理上的根本局限。然而，共产主义的认识论困境并非仅仅停留在“缺乏信息”的层面，它在经济学的底层逻辑上同样面临着一个不可逾越的结构性屏障——“产权—价格—激励”不可能三角。
任何一个社会要维持经济的持续运转、资源的有效配置以及技术的不断创新，必须同时满足三个基本条件：清晰的私有产权划分：作为市场交易与风险承担的法律前提；
自由形成的价格信号：作为衡量资源稀缺程度与引导经济计算的唯一尺度；
内生的有效激励机制：作为驱动个体付出劳动、承担风险与进行创新的动力源泉。
共产主义理论的核心诉求，正是试图通过全面废除私有制（建立公有制），来同时消灭价格机制与市场竞争，进而构建一个由全社会统一计划、按需分配的乌托邦。然而，经济学基本规律表明，这三者构成了一个互相锁定、缺一不可的有机整体。一旦消灭了私有产权，自由价格信号便失去了存在的根基，经济计算随之陷入瘫痪；而失去了价格信号与私有产权，基于个人利益与风险责任的有效激励机制便会瞬间瓦解，最终必然沦为普遍的惰性、严重的资源错配以及全社会性的物质匮乏。
本章将系统梳理二十世纪“社会主义经济计算大论战”的理论成果，深入剖析公有制下价格机制瘫痪的内在逻辑，并揭示公有产权如何不可避免地引发“公地悲剧”、代理人危机以及经济活力的全面衰竭。
第一节 算力无法替代市场：米塞斯“经济计算问题”的理论奠基
1920年，奥地利经济学派大师路德维希·冯·米塞斯发表了一篇题为《社会主义国家的经济计算》的划时代论文。这篇论文犹如一颗炸弹，彻底击碎了共产主义关于“计划经济比市场经济更高效”的理论神话，由此引发了二十世纪经济学界最著名的“社会主义经济计算大论战”。
一、什么是“经济计算”？
在讨论米塞斯的论断之前，必须首先厘清经济学中“技术计算”与“经济计算”的本质区别。
技术计算：关注的是“如何利用既定的物理手段达成某个具体的工程目标”。例如，建筑工程师可以利用物理学和力学原理计算出：建造一座跨海大桥需要多少吨钢材、多少立方米水泥、多少工时。这是一个纯粹的自然科学和技术工程问题。
经济计算：关注的是“在成千上万种可选的技术方案与资源组合中，哪一种方案在经济上是最划算的，最能够节约稀缺资源以满足全社会最紧迫的需求”。例如，建造这座大桥究竟应该用钢材、预应力混凝土，还是用木材？如果用钢材，这些钢材如果省下来去制造农用机械或者建造医院，是否会产生更大的社会价值？
在现实世界中，几乎任何一个生产目标都有多种技术路线可以实现。一个社会面临的根本问题并非“技术上能不能做”，而是“经济上值不值得做”。没有经济计算，人类就无法在无限的生产可能性中做出合理的选择，整个社会生产就会陷入无休止的资源浪费与盲目试错之中。
二、逻辑推导：没有私有产权，就没有真正的价格
米塞斯指出，合理的经济计算必须依赖一套统一的、能够动态反映资源稀缺程度的估值尺度。在现代复杂社会中，这套尺度只能是货币价格。米塞斯递进式地给出了社会主义无法进行经济计算的逻辑链条：
生产资料公有制：社会主义彻底废除了生产资料（工厂、土地、矿山、机器）的私有制，将其全部收归国有或集体所有。
交易行为的消失：由于所有的生产资料都属于同一个所有者（国家），生产资料在不同工厂和部门之间的流动，不再是买卖行为，而变成了同一个实体内部的行政调拨。
价格机制的瘫痪：没有买卖，就没有市场交易；没有市场交易，就无法形成真正的生产资料市场价格。
经济计算的破产：没有生产资料的价格，中央计划部门就无法计算任何工业品或工程项目的生产成本，也就无法比较不同生产方案的投入产出比。
在市场经济中，一个资本家在决定是否开采某座矿山时，他会计算矿石的预计售价与开采所需的设备、人工、运输成本。如果预计收益高于成本，说明该开采行为创造了价值；反之则说明是在毁灭价值。而在社会主义公有制下，由于生产资料没有市场价格，中央计划官员面对庞大的原材料和设备库存时，完全不知道它们的真实价值是多少。计划部门只能用物理单位（如几吨钢材、几千千瓦时电、几百个工时）来记录投入，但这完全是“将苹果与牛肉相加”。你无法用“3吨钢材 + 500度电”与“2吨木材 + 100个工时”去直接比较谁更节约，除非它们都能被折算为统一的货币成本。
社会主义的生产资料公有制将导致经济生活的完全盲目。中央计划当局可以在黑暗中摸索，但它永远无法知道自己的所作所为是否符合经济原则。
三、兰格模式的破产与现代“数字计划经济”谬误
针对米塞斯的批判，波兰马克思主义经济学家奥斯卡·兰格等提出了所谓的“竞争性社会主义”或“试错定价模型”。兰格主张，社会主义国家可以保留消费品市场，但在生产资料领域，中央计划部门可以扮演“市场”的角色（扮演的哪有真的好呢，说明还是需要价格系统）。计划部门先凭空设定一个初始价格，然后观察市场上该商品的供求状况：如果出现短缺就抬高价格，出现过剩就降低价格，通过不断试错来逼近“均衡价格”。米塞斯与哈耶克迅速对“兰格模式”进行了致命的反驳：
官僚缺乏承担风险的机制：自由市场中的价格试错是由无数自负盈亏的企业家用自己的真金白银进行的；而计划官员用国家的资产进行试错，既不承担失败的财务后果，也没有动力捕捉瞬息万变的市场契机。
静态拟合无法应对动态演化：兰格模型假设经济体系是静态的，计划部门只需计算出一组固定的均衡解。但现实经济是高度动态的，每分每秒都有新的技术、新的偏好、新的资源被发现。行政试错的速度远远落后于市场演化的速度。
现代变体：“算法与大数据能复活计划经济吗？”
随着云计算、人工智能与大数据技术的发展，现代某些“科技乌托邦主义者”重新拾起兰格的旧论，声称：“米塞斯时代的计划经济失败是因为当时缺乏算力。如今有了超级计算机与实时监控网络，中央系统可以实时获取每个人的消费数据，直接联立求解数千亿个联立方程式，从而实现‘数字计划经济’。”
这种观点完全误读了米塞斯与哈耶克的理论核心：
算力再强大，也只能处理已经发生的历史数据（如你昨天买了什么），而无法预测和计算在未来特定边际条件变化下人类的心理选择与主观估值。
更重要的是，没有自由价格，数据本身就是失真的。如果电商平台上的价格是行政管制的，那么抓取到的“消费数据”只反映了强制配给下的被动选择，绝不代表消费者真实的边际偏好。用超级计算机处理失真的数据，只会以更快的速度输出更加荒谬的计划指令，而不可能复活计划经济。

Why Communism Is Structurally Unattainable (A Series)
Author: Zhang Xinggui
Chapter One: The Epistemological Trap — Omniscient Rationality and the Limits of Knowledge (Section Four)
Chapter Two: The Economic Impossible Triangle — Property Rights, Prices, and Incentives (Section One)
Section Four: The Fallacy of Certainty — The Conflict Between Complex Evolutionary Systems and Linear Mechanistic Thinking
Another major epistemological flaw in communist theory, the author argues, lies in its reliance on an outdated linear and mechanistic worldview to interpret human society, which is fundamentally a complex, nonlinear, evolving system.
I. The Limitations of Reductionism and Mechanistic Materialism
Nineteenth-century physics was heavily influenced by reductionism and Laplacian determinism. Pierre-Simon Laplace famously proposed that if an intelligence—later known as “Laplace’s Demon”—knew the positions and momenta of all particles in the universe at a given moment, it could use the laws of Newtonian mechanics to calculate the state of the universe at any point in the past or future.
The communist conception of history, in the author’s view, was deeply influenced by this form of mechanical determinism. It attempted to reduce complex social transformations to a one-directional, linear chain of causation: “development of productive forces → transformation of relations of production.”
It assumed that by controlling the “master switch” of public ownership of the means of production, society could be engineered to produce a flawless communist order according to a predetermined plan.
Modern science, however—particularly systems theory, chaos theory, and complexity science—has revealed the limitations of such thinking. Social systems, composed of vast numbers of autonomous individuals interacting with one another, exhibit the characteristics of nonlinear complex adaptive systems.
II. Emergence and Unpredictability
In complex systems, the properties of the whole are not simply the linear sum of the properties of its individual components. Instead, they emerge through countless intricate local interactions.
Language, for example, was not designed all at once by an ancient linguist sitting in a study. Rather, it evolved spontaneously through the interactions of countless people over thousands of years.
Similarly, according to the spontaneous-order account of monetary origins, money was not invented by a single king. It emerged over time as participants in exchange selected commonly accepted media to reduce transaction costs.
Complex systems possess several fundamental characteristics that, the author contends, undermine the feasibility of comprehensive communist planning.
1. Emergent properties cannot be fully calculated in advance.
One cannot reliably predict the trajectory of a tornado merely by examining the properties of an individual molecule.
Likewise, a central planning authority cannot predict the dynamic evolution of market demand throughout an entire society simply by analyzing the productivity of individual workers.
2. The butterfly effect and sensitivity to initial conditions.
Social systems contain numerous positive and negative feedback loops. Small disturbances can sometimes trigger enormous chain reactions.
A seemingly minor administrative directive, such as adjusting the procurement price of an agricultural product, may produce cascading consequences that, under certain conditions, contribute to a nationwide agricultural collapse or famine years later.
3. Adaptive individual behavior.
Human beings are not chess pieces that can be moved at will across a board.
Adam Smith criticized precisely this kind of assumption in The Theory of Moral Sentiments, using the analogy of a political planner who imagines he can arrange members of society as easily as pieces on a chessboard.
When a government introduces a planning policy, individuals adjust their behavior in response.
They may participate in underground markets, reduce their work effort, or compromise production quality.
Such bottom-up adaptive responses can undermine the original intentions of top-down policies.
III. The Suppression of Trial and Error and the Amplification of Its Costs
The progress of human civilization is, in essence, a bottom-up process of experimentation, trial and error, and evolution.
In free societies and market economies:
Every day, thousands of entrepreneurs experiment with new technologies, business models, and organizational structures.
Many experiments fail, resulting in business closures, but the direct financial costs of failure are often concentrated among the firms, investors, and other parties involved.
A small number of successful experiments survive market competition, are imitated by others, and spread throughout society, thereby contributing to economic and technological progress.
This constitutes a highly effective evolutionary process.
Communist central planning, however, obstructs this bottom-up mechanism of experimentation.
Because comprehensive public ownership eliminates independent private capital and entrepreneurship, innovation and economic decisions become dependent on approval from central planning authorities.
The author identifies two fundamental epistemological problems arising from this arrangement.
1. The suffocation of innovation.
Innovative ideas that challenge established practices may be rejected by layers of bureaucratic approval simply because they do not conform to an existing Five-Year Plan.
Bureaucratic institutions tend to favor continuity, standardization, and predictable procedures, while resisting uncertainty and unconventional experimentation.
2. The nationwide amplification of mistakes.
In a market economy, a business owner’s poor decision may lead to the bankruptcy of a single company, although its consequences can sometimes extend to employees, creditors, and the broader economy.
Under centralized planning, however, decision-making authority is concentrated at the highest levels.
When central planners make serious mistakes, the administrative apparatus can transmit and amplify those mistakes throughout the entire country.
Examples include the policies of close planting and deep plowing during China’s Great Leap Forward, as well as the Soviet Union’s politically enforced promotion of Lysenkoism, a discredited theory of heredity.
Both cases illustrate how centralized political authority can magnify the consequences of erroneous scientific or economic assumptions.
Chapter One Conclusion: The Logic of Epistemological Failure
In summary, the author argues that communism is ultimately unattainable not because moral standards are insufficiently developed or because particular administrators lack competence, but because its theoretical framework rests upon fundamentally flawed epistemological assumptions.
Communist theory, as characterized in this critique, makes several assumptions:
Historical determinism: Human beings can fully comprehend the objective laws governing historical development.
The illusion of the omniscient planner: Central authorities can collect and process all economic and social information throughout society.
The knowledge problem identified by Friedrich Hayek: Complex social knowledge can be completely quantified and centralized, disregarding the dispersed and tacit knowledge essential to the functioning of society.
The mechanistic fallacy: Human society can be precisely designed and controlled from above, rather than understood as a complex system capable of spontaneous evolution.
When a political and economic theory violates the practical constraints of information transmission, the limits of human rationality, and the evolutionary dynamics of complex systems, the author concludes, its collapse becomes not a question of whether it will occur, but when.
Abandoning the arrogance of “omniscient rationality,” acknowledging the limitations of human knowledge, and recognizing that society cannot be comprehensively designed are essential steps toward greater rationality and maturity.
Only on this epistemological foundation, the author maintains, can institutions based on decentralization, the protection of private property rights, respect for spontaneous order, and freedom of choice provide lasting safeguards for human prosperity and dignity.
Chapter Two: The Economic Impossible Triangle — Property Rights, Prices, and Incentives
In Chapter One, we examined communism’s epistemological difficulties, particularly its aspiration toward “omniscient rationality,” and explained the fundamental limitations of central planning in collecting and processing information.
However, communism’s epistemological problems do not end with a lack of information.
At the foundational level of economics, the author argues, communism confronts another seemingly insurmountable structural barrier: the impossible triangle of property rights, prices, and incentives.
For any society to sustain economic activity, allocate resources effectively, and continuously generate technological innovation, three fundamental conditions must be satisfied:
Clearly defined private property rights: The legal foundation for market transactions and the assumption of economic risk.
Freely formed price signals: The mechanism through which resource scarcity is expressed and economic calculation is guided.
Effective endogenous incentives: The driving force that motivates individuals to work, assume risks, and innovate.
The central objective of communism, as presented in this critique, is to abolish private ownership of the means of production, replace it with public ownership, eliminate market competition and the market price mechanism, and establish a unified system of social planning and distribution according to need.
The author contends that these three economic conditions form an interconnected system in which each depends upon the others.
Once private property rights are eliminated, freely formed price signals lose their institutional foundation.
Without meaningful price signals, rational economic calculation becomes severely impaired.
And without market prices and private ownership, incentive mechanisms based on personal benefit, risk, and responsibility are weakened.
The resulting system, according to the author’s argument, tends toward widespread economic passivity, serious resource misallocation, and material shortages.
This chapter will systematically examine the twentieth-century socialist economic calculation debate, analyze the theoretical difficulties of establishing meaningful prices under comprehensive public ownership, and explore how collective ownership may generate problems associated with the tragedy of the commons, principal-agent conflicts, and declining economic dynamism.
Section One: Computing Power Cannot Replace the Market — Ludwig von Mises and the Foundations of the Economic Calculation Problem
In 1920, the Austrian School economist Ludwig von Mises published his influential essay Economic Calculation in the Socialist Commonwealth.
The essay challenged the claim that a centrally planned socialist economy could allocate resources more efficiently than a market economy.
It became one of the foundational contributions to the twentieth-century socialist economic calculation debate.
I. What Is Economic Calculation?
Before examining Mises’s argument, it is necessary to distinguish between technical calculation and economic calculation.
Technical calculation concerns how given physical means can be used to achieve a particular engineering objective.
For example, a civil engineer can apply physics and mechanics to determine how many tons of steel, how many cubic meters of concrete, and how many labor hours are required to construct a bridge across the sea.
This is primarily a question of natural science and engineering.
Economic calculation, by contrast, asks which of the many technically feasible methods and combinations of resources is economically preferable, conserving scarce resources while satisfying society’s most urgent needs.
For example, should the bridge be constructed from steel, prestressed concrete, or timber?
If steel is used, might that same steel have generated greater social value if it had instead been used to manufacture agricultural machinery or construct hospitals?
In the real world, almost every production objective can be achieved through multiple technical methods.
The fundamental economic question is therefore not simply whether something can be produced, but whether producing it is worth the resources sacrificed.
Without economic calculation, society cannot meaningfully compare competing uses of scarce resources.
Production decisions risk becoming a process of wasteful experimentation and poorly informed allocation.
II. The Logical Argument: Without Private Ownership, There Can Be No Genuine Market Prices
Mises argued that rational economic calculation requires a common unit of valuation capable of reflecting the relative scarcity of resources under changing conditions.
In a modern, complex economy, he maintained, this function is performed by monetary prices.
Mises developed a sequence of arguments explaining why comprehensive socialist ownership would undermine economic calculation.
1. Public ownership of the means of production
Under comprehensive socialism, private ownership of productive assets—factories, land, mines, and machinery—is abolished.
These assets become the property of the state or collective institutions.
2. The disappearance of genuine market transactions
When all means of production are controlled by a single owner, the state, transfers between factories and departments no longer constitute genuine exchanges between independent owners.
Instead, they become administrative allocations within the same overarching organization.
3. The breakdown of the price mechanism
Without buying and selling in markets for the means of production, genuine market prices for those assets cannot emerge.
4. The failure of economic calculation
Without market prices for productive resources, central planners cannot reliably determine the monetary opportunity costs of industrial goods or major projects.
Consequently, they lack a meaningful basis for comparing alternative production methods and evaluating their relative economic efficiency.
In a market economy, an entrepreneur deciding whether to develop a mine estimates the expected selling price of its output and compares it with the costs of equipment, labor, transportation, and other inputs.
If the expected revenues exceed the relevant costs, the project may be economically worthwhile.
If the costs exceed the expected revenues, the project may destroy rather than create economic value.
Under comprehensive socialist public ownership, however, productive assets lack independently formed market prices.
Central planners may know the physical quantities of raw materials and equipment available, yet remain unable to determine their relative economic values.
Planning authorities can record inputs in physical units—tons of steel, kilowatt-hours of electricity, or labor hours—but these quantities cannot be directly compared without a common measure of economic value.
For example, how can one determine whether the following production methods are more economical?
Three tons of steel plus 500 kilowatt-hours of electricity.
Two tons of timber plus 100 labor hours.
Without a common monetary valuation of the resources involved, the two combinations cannot be meaningfully compared in terms of their opportunity costs.
It would be like attempting to add apples and beef together as though they were directly comparable quantities.
Mises therefore argued that comprehensive public ownership of the means of production would leave economic decision-makers operating without the essential guidance of market prices.
Central planning authorities might continue making decisions, but they would lack a reliable means of determining whether those decisions represented economically rational uses of scarce resources.
III. The Failure of the Lange Model and the Modern Fallacy of Digital Central Planning
In response to Mises’s criticism, the Polish economist Oskar Lange and other socialist economists developed models commonly associated with market socialism and trial-and-error pricing.
Lange proposed that a socialist economy could retain markets for consumer goods while allowing a central planning authority to perform certain functions analogous to those of a market for productive resources.
The planning authority would initially assign prices to goods and then observe shortages and surpluses.
If demand exceeded supply, the authority would raise the relevant price.
If supply exceeded demand, it would lower the price.
Through repeated adjustments, prices would theoretically move toward equilibrium.
The author notes that this proposal itself acknowledges the importance of a functioning price system, while questioning whether an administratively simulated market can reproduce the performance of a genuine one.
Mises and Hayek raised fundamental objections to this approach.
1. Bureaucrats lack direct mechanisms of financial risk and responsibility.
In competitive markets, entrepreneurs experiment with prices, products, and production methods while bearing financial consequences through profits and losses.
Central planning officials, by contrast, make decisions using publicly owned resources.
They generally do not personally bear the financial losses caused by unsuccessful decisions and may have weaker incentives to identify rapidly changing market opportunities.
2. Static equilibrium models cannot adequately capture dynamic economic evolution.
The Lange model, according to this critique, relies heavily on the assumption that an economic system can be represented by a set of equilibrium conditions.
Central planners would then attempt to identify the prices consistent with those conditions.
Real economies, however, are continuously evolving.
New technologies emerge, consumer preferences change, resources are discovered, and production methods are transformed.
The author argues that administrative price adjustments are unlikely to keep pace with this decentralized process of discovery and adaptation.
A Modern Variation: Can Algorithms and Big Data Revive Central Planning?
With the development of cloud computing, artificial intelligence, and big data, some contemporary advocates of technologically enabled planning have revived arguments resembling earlier proposals for centralized economic coordination.
They contend that the failures of twentieth-century central planning resulted partly from inadequate computational capacity.
Today, they argue, supercomputers and real-time data networks could enable a central system to collect detailed information about consumption and production and solve vast systems of simultaneous equations.
In theory, such a system could make digital central planning possible.
The author argues that this position misunderstands the central insights of Mises and Hayek.
No matter how powerful a computer becomes, processing historical data alone cannot fully reveal how individuals will respond to future changes in prices, opportunities, and constraints.
A system may know what a consumer purchased yesterday, but that information does not necessarily reveal the consumer’s subjective valuation under different circumstances tomorrow.
More importantly, the author argues, without freely formed prices, the economic meaning of the collected data may be distorted.
If prices on an e-commerce platform are administratively controlled, the observed consumption patterns may reflect the constraints imposed by regulation or rationing rather than consumers’ preferences under freely changing market conditions.
In such circumstances, collecting and processing larger quantities of data does not necessarily solve the underlying information problem.
A supercomputer may simply generate more detailed planning instructions from distorted signals.
According to the author, increasing computational power cannot, by itself, restore the decentralized price formation, entrepreneurial discovery, and economic incentives that comprehensive central planning suppresses.
