We study mechanisms leading to wealth condensation. As a natural starting point, our model adopts a neoclassical point of view, i.e., we completely ignore work, production, and productive relations, and focus only on bilateral link between two randomly selected agents. We propose a simple matching process with deterministic trading rules and random selection of trading agents. Furthermore, we also neglect the internal characteristic of traded goods and analyse only the relative wealth changes of each agent. This is often the case in financial markets, where a traded good is money itself in various forms and various maturities. We assume that agents trade according to the rules of utility and decision theories. Agents possess incomplete knowledge about market conditions, but the market is in equilibrium. We show that these relatively frugal assumptions naturally lead to a wealth condensation. Moreover, we discuss the role of wealth redistribution in such a model.

导致财富集中的简单机制


我们研究导致财富凝聚的机制。作为一个自然的起点，我们的模型采用了新古典主义的观点，即我们完全忽略工作、生产和生产关系，而只关注两个随机选择的主体之间的双边联系。我们提出了一个简单的匹配过程，具有确定性的交易规则和随机选择的交易代理。此外，我们还忽略了交易商品的内部特征，仅分析每个主体的相对财富变化。在金融市场中经常出现这种情况，其中交易的商品就是各种形式和各种期限的货币本身。我们假设代理人根据效用规则和决策理论进行交易。代理人对市场状况的了解不完全，但市场处于均衡状态。我们表明，这些相对节俭的假设自然会导致财富浓缩。此外，我们还讨论了财富再分配在这种模型中的作用。
