We develop a model of rational bubbles based on leverage and the assumption of an imprecisely known maximum market size … lend to traders with limited liability in a bubble is endogenous. Bubbles reduce welfare of future investors. We provide … general conditions for the possibility of bubbles depending on uncertainty about market size, traders' degree of leverage and …

First, we introduce the quantile regression to the …\textsuperscript{TM} and Trust\textsuperscript{TM} indicators that enrich considerably the diagnostic of bubbles. Using extensive synthetic … signals, a detailed analysis of the "S\&P 500 1987" bubble and the application to 16 historical bubbles, we show that the …

It is empirically noticeable that bubbles do not burst but deflate over time. This paper brings some theoretical … foundations to this observation. Using multi-agent-based simulations, the limited-arbitrage theory of the risk of synchronisation … and a measure of bubble crashes, it is possible to demonstrate that bubbles deflate. The agents are not able to …

Building on the notion that bubbles are transient self-fulfilling prophecies created by positive feedback mechanisms …

Financial bubbles are subject to debate and controversy. However, they are not well understood and are hardly ever … specific traces, bubbles may be recognised in advance: that is, before they burst. In this paper, we will explain the mechanism … behind financial bubbles in an intuitive way. We will show how the log-periodic power law emerges spontaneously from the …
