This paper compares two different types of private retirement plans from the perspective of a representative beneficiary: a defined benefit (DB) and a defined contribution (DC) plan. While salary risk is the main common risk factor in DB and DC pension plans, one of the key differences is that...

Developed countries apply different security mechanisms in regulation to protect pension benefits: solvency requirements, a pension guarantee fund, and sponsor support. We compare these mechanisms for a generalized form of hybrid pension schemes. We calculate the expected log return for the...

Developed countries apply different security mechanisms in regulation to protect defined pension benefits: solvency requirements, a pension guarantee fund, and sponsor support. We test the performance of these mechanisms in terms of the protection offered to pension benefits in relation to the...

This paper compares two diff erent types of private retirement plans from the perspective of a representative benefi ciary: De fined Benefi t (DB) and Defi ned Contribution (DC) plan. One of the key di fferences is that DB plans carry portability risks, whereas DC plans bear asset and...

The present paper analyzes optimal supervisory rules for pension funds taking account of diverse pension security mechanisms: support provided by either a pension guarantee fund, a plan sponsor or by both. Assuming that the regulatory rule is either to control the shortfall probability or...

This paper studies a non-concave optimization problem under a Value-at-Risk (VaR) or an Expected Shortfall (ES) constraint. The non-concavity of the problem stems from the non-linear payoff structure of the optimizing investor. We obtain the closed-form optimal wealth with an ES constraint as...

The present paper analyses an optimal consumption and investment problem of a retiree with a constant relative risk aversion (CRRA) who faces parameter uncertainty about the financial market.We solve the optimization problem under partial information by making the market observationally complete...
