The automatic adjustment of Spanish Pensions. End-of-project talk delivered in September 2013 in the research seminar of the Bank of Spain. It summarizes a general equilibrium exploration of the effects of the 2013 reform of the Spanish pension system, including a new automatic adjustment mechanism. It also compares the General Equilibrium methodology with other methodological approaches

2. Septiembre 2013: the government presents it proposal for the design of the
pension sustainability factor
Se garantiza la subida de las pensiones, que crecer´an como
m´ınimo un 0,25% anual
Su compromiso es asegurar a todas las generaciones una
pensi´on garantizando un trato equitativo; de forma que los
esfuerzos similares de aportaci´on obtengan retornos similares
de la prestaci´on a lo largo del tiempo.

9. Restoring the balance
Political authorities have reacted by “reforming” the system:
Occasional parametric changes (1997, 2002, 2011);
Introducing ABM (Automatic Balancing Mechanisms)

Idea:
- Adopt a macro scenario: demog, employment, prod.
- Conjecture impact on coverage and dynamics of replacement
(with/without reforms);
- Do sensitivity analysis.
Pros & cons: Good: range of possible financial outcomes;
Problem: coherence of the different pieces is not granted; Hard to do
intergenerational comparisons ;

15. Projection Methodology
(ii) Partial equilibrium Microsimulation
Idea: (1) Create a representative sample; (2) estimate labor dynamics conditional
on macro; (3) given the macro scenario, create in sample simulated labor records;
(4) compute pension aggregates.

(ii) Partial equilibrium Microsimulation
Idea: (1) Create a representative sample; (2) estimate labor dynamics conditional
on macro; (3) given the macro scenario, create in sample simulated labor records;
(4) compute pension aggregates.
Pros & cons:
Good: Detailed reproduction of pension regulations; Intergenerational income
comparisons
Bad:
Imposes historical behavior under different institutional settings
Lack of feedback between individual performance and macro
assumptions
Welfare analysis.

(iii) General Equilibrium
Idea: Fundamentals: preferences; technology; institutions + Exogenous
demographics, & productivity growth
Solve individual behavior, aggregate to compute macro-variables.

18. Projection Methodology
(iii) General Equilibrium
Idea: Fundamentals: preferences; technology; institutions + Exogenous
demographics, & productivity growth
Solve individual behavior, aggregate to compute macro-variables.
Pros & cons:
Some endogenous behaviour; feedback behavior → macro.
Macro coherence: aggregates emerge from individual behavior
Standard Welfare analysis.
Bad: we can only solve stylized worlds. Otherwise, huge computation costs, specially
with uncertainty

20. The GE model
Model overview
OLG model in the Auerbach & Kotlikoff (87): 1 year=1 period
Build-in demographic model (exogenous fertility, mortality and migration patterns)
Closed Economy with flows of immigrants
No aggregate uncertainty. Life uncertainty at the individual level.
“Representative” Households pools LU
Heterogenous Households that take consumption/savings and retirement decisions.
Exogenous:
(1) participation and unemployment patterns (vs. Fiscal Studies (2010))
(2) labour-augmenting technological progress (at rate ρt
)
Neoclassical production side
Seminario Banco de Espa˜na () Pension automatic adjustment September 19, 2013 12 / 56
21. The GE model
Households Heterogeneity
Representative Households by cohort, that differ by:
1 Education
2 Relative value of leisure → heterogeneity in retirement behavior
Seminario Banco de Espa˜na () Pension automatic adjustment September 19, 2013 13 / 56
22. The GE model
Households Heterogeneity
Representative Households by cohort, that differ by:
1 Education
2 Relative value of leisure → heterogeneity in retirement behavior
Within each Rep Household, the proportion of households with
one/two members changes with age (due to the action of mortality)
→ we have 4x80x10= 3200 different agents each period & 250 periods per simulation;
still very computationally tractable.

The Status Quo system is that in place after 2011’s reform (R11),
featuring:
(i) Delay of the Statutory Retirement age 65 → 67;
(ii) Delay of the Early Retirement age 61 → 63;
(iii) Increase in the length of the pensions’ averaging period (15 → 25);
(iv) Minimum pension expenditure is transferred to the general budget.

Depending on the environment, the deficits (tax hikes) vary from

Sizable behavioral reaction to eg. pmax/pmin policy.
2 Reforms: If implemented, the sept-2013 proposal will be the most
ambitious attempt to restore the financial balance of the pension
system.
In our BASE environment, it fails to fully restore the financial balance
(Adjustments needed are too strong, hitting the lower limits in pension
depreciation) . Notwithstanding, it goes a long way towards that target.
Large imbalances remain in tougher macro/demographic environments
