  The Keen model is a mathematical model that describes the dynamic evolution
of wages, employment, and debt based on the known Minsky's Financial
Instability Hypothesis. It consists of three first order nonlinear ordinary
differential equations. There exists an equilibrium state that corresponds to a
collapse of both wage and employment but certain debts remain. In this paper,
we construct an example in which this equilibrium appears to be stable. More
interestingly, the debt becomes negative, which indicates some source of income
without laboring.
