本文研究了银行间交易或有可转换债券和股票价格之间相互触发时均衡价格的存在性和唯一性。这类金融产品是在金融危机后作为稳定全球银行体系的工具提出的。然而,人们很早就认识到,即使在没有交易的情况下,这些产品也可能在股票价格的定义中造成循环问题。我们发现,如果转换阈值为债券持有者对边际转换不感兴趣,则无论网络结构如何,都存在唯一的均衡。当阈值较低时,平衡态的存在性被打破,而阈值较高时,平衡态的多重性可能会出现。而且,还存在着复杂的网络效应。一家银行的转换可能会引发进一步的转换--或阻止它们,这取决于资产价值和转换触发器的星座。

英文摘要:
This paper studies existence and uniqueness of equilibrium prices in a model of the banking sector in which banks trade contingent convertible bonds with stock price triggers among each other. This type of financial product was proposed as an instrument for stabilizing the global banking system after the financial crisis. Yet it was recognized early on that these products may create circularity problems in the definition of stock prices - even in the absence of trade. We find that if conversion thresholds are such that bond holders are indifferent about marginal conversions, there exists a unique equilibrium irrespective of the network structure. When thresholds are lower, existence of equilibrium breaks down while higher thresholds may lead to multiplicity of equilibria. Moreover, there are complex network effects. One bank\'s conversion may trigger further conversions - or prevent them, depending on the constellations of asset values and conversion triggers.
