Policy question
The aging of population has been the triggerwhich sparked off the highest expenditure inretirement pensions in the Spanish pay as yougo system, although this has not been the onlyvariable which has affected it. The slow growthof the population, the weakness of the jobmarket, and the increasing dependency ratio, arethe main drivers of our variable of interest.
Given this reality, does the government need toimplement any measure to keep that figureunder control?

Variables
Our variable of interest is the amount of moneythat is going to be allocated to retirementpensions as a percentage of GDP, in the next 5quarters.
The covariates used are then GDP, LaborProductivity, Dependency ratio and Employmentrate. Among them, the Dependency ratio andthe Employment rate are treated as exogenous
variables. Productivity and GDP are classicalmacroeconomic variables, and difficult not to beclearly related each other, as well as any kind ofGovernment expenditure.

Policy Recommendation
As we can see in the last slide, the trend is accelerating dangerously,both because of a drop in the level of GDP and the steady growth of thepensions expenditure.
Anyway we have to note that this forecast is very short time and this isan exercise to be done every year at least, because as we can see, unless
any other policy is implemented regarding the increase of laborproductivity, or reducing the unemployment rate or better inmigrationpolicies, the figure is going to get worst.
The forecast shows that the Spanish government should accomplish assoon as possible this problem, either by implementing policies toincrease the income part of the ratio (GDP, productivity, employment),or/and to decrease the amount to expend in pensions. The first policiesare difficult because they do not have an immediate effect, while thesecond ones are short term. Longer retirement age and no earlyretirement option are the quick ones, but with possible social sideeffects.
