Objectives of a National Pension System
1. Primary Objectives:
a) Assure retired/disabled a minimum income
b) Assure minimal degree of earnings replacement
2. Secondary Objectives:
a) Increase national savings
b) Promote financial market development
c) Help restructure failing (state) enterprises
d) Minimize adverse side effects
e) Secure high returns on contributions
5
Three Common Elements (Pillars) of a Retirement Income System
1. Redistribution program(s)
a. Defined benefit, pay-as-you-go, usually government operated
2. Mandatory earnings or contribution-related program(s)
a. Defined benefit and/or defined contribution
b. Pay-as-you-go and/or advance funded
c. Government and/or private operation
3. Voluntary programs
a. Advance funded, private operation
b. Increasingly defined contribution
c. Government oversight and subsidies

Issues Affecting Second Pillar Design:Size and Structure of Other Components
1. Level of minimum income guarantee
– Establishes floor
2. Size of total mandatory component
– Limits the size of the 2nd pillar
3. Structure of minimum income guarantee
– Affects incentive structure
– Also influences size of 2nd pillar

Structure of Minimum:Two Approaches
1. Fill the Gap
– Acts as a supplement to top up a second component benefit
– Found in Chile, Sweden, U.S.
2. Flat minimum
– Provides floor that second component is built upon
– Found in Russia, China, U.K., Netherlands, Denmark

Comparison of Approaches
Flat grant:1. Uniform coverage in dignified manner2. Fewer disincentives (at least from benefit side!) 3. Less room for earnings-related component4. More budget resources5. Easier to administer• Fill the gap minimum:1. Fewer budget resources to finance2. More room for earnings-related component3. More difficult to administer, particularly if means-tested4. Compliance, savings and labor market disincentives5. Contingent liabilities
15
Issues Affecting Second Pillar Design:Size and Distribution of System Risks
1. Of particular concern in pension programs:
a. Few alternative income sources at point of eligibility
b. Long lead time for individual supplementation
2. Major sources of risk
a. Demographic
b. Financial
c. Political/Institutional
16
Demographic Risk
Two elements:
1. Change in mortality among aged
– Affects both funded and unfunded schemes
2. Change in birth rate (or net immigration)
– Affects unfunded schemes directly through change in beneficiary/worker ratio
– Affects funded schemes indirectly through changes in relative factor prices
17
Incidence of Unanticipated Demographic Change
1. Defined contribution scheme:
– Impact entirely on retired worker
2. Defined benefit scheme:
– Initial impact on plan sponsor (or state)
– Ultimate impact likely to be shared between contributors and beneficiaries, at least initially
18
Financial Risk
1. Of concern mainly in funded plans*.
2. Two elements of financial risk:
– Change in ratio of mean returns to mean wage growth rate
– Variation in annual mean returns and growth rates around known mean
* cost of unfunded plans can be sensitive to changes in real wage growth rate

21
Impact of Variations around the Mean
Analytical approach:1. Examine impact of variation in wage growth, investment returns,
and annuity interest rate2. Monte Carlo experiment with actual mean and standard deviation of
annual wage growth and annual average investment returns, 1953-953. Examine impact of four structures:
a. Traditional defined benefit -- sponsor absorbs all risksb. TIAA model -- wages (and contributions) vary; sponsor
smoothes other variationsc. Swedish model -- wages and accumulation returns vary; sponsor
smoothes annuity interest variationd. Chile model -- worker assumes all risks

Incidence of Financial Market Risk
1. Risk of change in mean growth or return rate:a. Defined contribution scheme: Risk born entirely by retiring
workerb. Defined benefit scheme:
– Initial impact on plan sponsor (or state plan)– Ultimate impact likely to be shared between contributors
and beneficiaries2. Risk associated with variance in growth rates & returns:
a. Defined benefit scheme: no riskb. Defined contribution scheme:
– Risk born entirely by retiring worker – Size of risk depends on plan design
26
Political/Institutional Risks
1. Unsustainable benefit promises
2. Decision gridlock
a. Cutting back defined benefits (France)
b. Resolving fiscal imbalances (Argentina)
3. Benefit adjustments to meet budget targets
4. Asset mismanagement
a. Political interference
b. Private mismanagement / regulatory failure
5. Underestimated transition costs

Issues Affecting 2nd Pillar Design:Worker Choice
1. Type of choice:
a. Portfolio composition
b. Asset manager
c. Plan managers
2. Reason for providing choice:
a. Worker preferences
b. Political insulation
c. Improve quality of service
29
Issues Affecting 2nd Pillar Design:Administrative Costs
1. Reduce investment returns
a. Limit (eliminate?) ability to lower contributions through advance funding
2. Vary with:
a. Degree of individual choice
b. Degree of centralization of administration
c. Level of service offered
3. May serve as insurance against certain forms of political risk

a. Collecting contributions
b. Keeping individual account records
c. Paying benefits
4. Degree of worker choice

Concluding Observations I
1. Risks in pension system:
a. All models have risks, but nature and size varies from one model to another
b. Some forms of financial risk are unique to defined contribution plans
2. Individualization of pension provision:
a. Increases financial risk (variation around the mean)
b. Shifts more of demographic and financial risks to individual retired workers
c. Tends to increase administrative costs
d. Allows greater choice (to what end?)
38
Concluding Observations II
3. Structure of second pillar influenced by: a. Relationship between minimum benefit and ceiling on mandated
benefitb. Political traditions
1) Pattern of political risks in each society2) Governance traditions
c. Preferences for:1) Providing choice in the mandatory system2) Spreading risks among general population
4. High administrative costs are:a. Either political insurance policy or (in part) dead weight lossb. Hard to reduce (costs are incomes)
