==Reference(s)==
==The Model==
Until <math>t=0\,</math> the budget is balanced, with debt . At <math>b_0 \ge t=0\,</math>. At a shock hits reducing tax revenues, which implies with debt <math>t=b \ge 0\,</math> a shock hits reducing tax revenues. After <math>t=0\,</math> until stabilization, <math>(1-\gamma)\,</math> of government expenditure including interest payments is covered by issuing debt, and <math>\gamma\,</math> is covered by distortionary taxation, where <math>\gamma >0\,</math> but not fixed.
Denoting <math>g_0\,</math> as the level of expenditure, debt <math>b(t)\,</math> evolves according to:
<math>\underbrace{\frac{db}{dt}}_{\mbox{Change in debt}} = \overbrace{(1-\gamma)}^{\mbox{deficit}}\times\underbrace{[rb(t) + g_0]}_{\mbox{Total government spending}}\,</math>
Taxes before stabilization are therefore:
:<math>\underbrace{\tau(t) }_{\mbox{Taxes}} = \overbrace{\gamma}^{\mbox{Taxed percent}}\times\underbrace{(rb(t) +g_o)}_{\mbox{Total expenditures}}\,</math>
:<math>\therefore \tau(t) = \gamma r \bar{b}^{(1-\gamma)rt}\,</math>
