This paper shows that underground activities and tax evasion may be another possible source of local indeterminacy of the equilibrium path. We derive necessary and sufficient conditions for equilibrium path to be locally indeterminate under tax evasion and underground activities. Moreover, the...

Galí (2014) showed that a monetary policy rule that raises interest rates in response to bubbles can paradoxically lead to larger bubbles. This comment shows that a central bank that wants to dampen bubbles can always do so by raising interest rates aggressively enough. This result is different...

I construct an infinite-horizon dynamic stochastic general equilibrium model with a collateral constraint and actual default in equilibrium. Entrepreneurs borrow from households through non-recourse debt contracts backed by capital goods. By taking into account the non-linear payoffs of the...

This paper analyses two types of models: 1. Those based on assumptions of monetary and financial market equilibrium disturbance in line with mainstream thinking that there is self-regulating market, the units would have rational expectations, and the crisis would be a temporary phenomenon caused...
