The SGP
• A set of regulations that complement the Maastricht treaty.
• Strengthens treaty provisions, extends them.
• Approved in 1997, revised in 2005 (after enforcement waseffectively abandoned).
• Limits on deficit/GDP, debt/GDP (debt/GDP effectively notenforced).
• Original version: deficit/GDP < 3%, except in case of asevere recession

• Europe has low mobility, growth: close to Ricardianequivalence
• If investment excluded, should be net

Computational algorithm
Object to be computed:
• Allocation, as a function of state:
cy , co , l , k ,B,T
• Policy choice, as a function of state:
G , Γ
• Derivatives of allocation wrt policy, as a function of state,evaluated at the policy choice:
(∂(cy , co , l , k ,B, τ)
∂G,∂(cy , co , l , k,B,T )
∂Γ)
System of nonlinear equations, solve for fixed point as fn. of state.
