This paper sets out the economic analytics of pensions. After introductory discussion, successive sections consider the effects of different pension arrangements on labour markets, on national savings and growth, and on the distribution of burdens and benefits. These areas are controversial and politically highly salient. While open about expressing our own views, the main purpose of the paper is to set out the analytical process by which we reach them, to enable readers to form their own conclusions. 1 The backdrop This paper has a two-fold purpose. It sets out the economic analytics of pensions without discussion of empirical magnitudes and outside the context of any particular country, with the intention of giving readers a systematic way of thinking about the topic. The paper is also intended as a contribution to a continuing debate, hence part of the discussion rebuts arguments that we regard as false, or equivocal, or true in some circumstances but not necessarily always. Specifically, we argue that much analysis is incomplete and oversimplified: focussing on one objective while ignoring others; assuming an idealised economy with well-informed agents and no distortions such as taxes and missing markets; comparing one steady state with another, when the underlying issue is a move from one steady state to a different one; or ignoring distributional effects. The opening section sets out some background matters: the objectives of pension systems, types of pension arrangement, and the economics of pensions. Sections 2, 3 and 4 discuss in turn pensions and labour markets (mainly microeconomic), finance and funding (mainly macroeconomic), and distributional issues.
