      "en" => "Using a simple model with two groups of agents, risk-averse mean-variance and stop-loss investors, we find that active selling by the latter causes price instability and may cause crashes , moreover, even in the absence of active trading on their part, their presence increases the volatility and decreases the equilibrium price in the periods preceding their possible activity."
