Moreover, arbitrage credit bubbles for both base credit assets … and credit derivatives are explicitly computed for the market dynamics minimizing the arbitrage …

A central conjecture of behavioural finance is that arbitrage opportunities appear as a result of systematic irrational … investment behaviour and persist since real-world arbitrage trades actually involve costs and risks due to market frictions and … non-fundamental risk.
