This paper studies equilibrium effects of fiscal policy within a dynamic general equilibrium model where tax evasion and underground activities are explicitly incorporated. In particular, we show that a dynamic general equilibrium with tax evasion may give a rational justification for a variant...

In this paper we use the property that certainty equivalence, as implied by a first-order approximation to the solution of stochastic discrete-time models, breaks in its equivalent continuous-time version. We study the extent to which a first-order approximated solution built by perturbation...

This paper shows under indeterminacy and tax evasion, an increase in corporate, labor or income tax rates pushes the economy into an expansionary pattern. These effects are reversed when the steady state is saddle-path stable

This paper introduces underground activities and tax evasion into a one sector dynamic general equilibrium model with external effects. The model presents a novel mechanism driving the self-fulfilling prophecies, which is triggered by the reallocation of resources to the underground sector to...

This paper studies equilibrium effects of fiscal policy within a dynamic general equilibrium model where tax evasion and underground activities are explicitly incorporated. There are three main results. (i) The underground sector mitigates the distortionary impact of fiscal policies, while...

This paper studies optimal bank capital requirements in a model of endogenous bank funding conditions. I find that requirements should be higher during good times such that a macroprudential "buffer" is provided. However, whether banks can use buffers to maintain lending during a financial...
