As we noted in our introduction to the first issue of the Journal, the mission of the journal is to serve as a forum for the international debate on pension provision. We are therefore keen as the Editors that the articles and ideas discussed in each issue are made accessible to as broad an audience as possible. This ‘Overview’ will introduce each issue, reviewing what the editors view as the main results and context for each article.

The paper estimates the impact of social security reform – specifically, the transition from a purely public pay-as-you-go (PAYGO) system to one with private individual retirement accounts – on the share of the workforce that contributes to formal retirement security systems. Using a simple model of a segmented labor market, the paper exploits variation in data from a panel of eighteen Latin American countries, observed from 1980 to 1999. Results show a positive incentive effect after the introduction of individual retirement accounts that, ceteris paribus, increases the share of the economically active population who contribute to the reformed system. However, this takes place only gradually as employers and workers become familiar with the set of new social security institutions that reforms put in place.

As one possible solution to the well-known financing crisis of unfunded social security systems, an increase in the retirement age is a popular option. To induce workers to retire later, it has been proposed to strengthen the link between retirement age and benefit level. The present paper is devoted to analyzing the long-run financial implications of such a reform. We show that with actuarial adjustments the long-run contribution rate is an increasing function of the retirement age chosen by workers. Moreover, the implicit tax paid to the pension system by a participant can increase in the long run if the retirement age rises in response to a ‘steep’ adjustment rule. In this sense, the proposed ‘cure’ may worsen the disease. Finally, we show how the negative effects can be avoided by forming a capital stock from the additional revenues due to later retirement.

Using data from the 1998 Survey of Consumer Finances, this paper examines the impact of dual private pension households on the distribution of household wealth in the United States. This paper builds on three lines of previous research: inquiries into ‘assortative mating’, i.e., the tendency for people with similar characteristics to marry; studies emphasizing the importance of pensions as a component of household wealth; and recent research examining how wives' earnings alter the distribution of household income. Evidence of ‘assortative private pensions’, i.e., the tendency for people with private pensions to be married to people with private pensions, is presented. Estimates of the expected value of private pension and social security wealth are added to measures of household non-retirement net worth to obtain the value household wealth. These data indicate that wives' private pensions in dual private pension households contribute marginally to greater equality in the wealth distribution.

This paper examines the rationale, nature and financial consequences of two alternative approaches to portfolio regulations for life insurers and pension funds, namely prudent person rules and quantitative portfolio restrictions. The argument draws on the financial-economics of investment and the differing characteristics of institutions' liabilities, as well as evidence drawn from major OECD countries. The overall conclusion is that prudent person rules are superior to restrictions, particularly for pension funds, except in certain circumstances that may hold temporarily in emerging market economies.
