Underfunding of Defined Benefit Pension Plans and Benefit Guarantee Insurance - An Overview of Theory and Empirics

We review the theoretical literature on defined benefit (DB) pension plans, particularly focusing on the issue of plan underfunding and benefit guarantee insurance schemes. The literature shows that underfunding can, under reasonable assumptions, be an equilibrium outcome even in the absence of benefit insurance. The introduction of benefit guarantee funds was a reaction to the problem of underfunding, and we summarize the ensuing standard problems of moral hazard and adverse selection. We briefly discuss the small empirical research on the subject and propose directions for future research.defined benefit pension plans, underfunding, pension benefit guarantee

Does Tax Competition Tame the Leviathan?

We study the impact of tax competition on equilibrium taxes and welfare, focusing on the jurisdictional fragmentation of federations. In a representative-agent model of fiscal federalism, fragmentation among jurisdictions with benevolent tax-setting authorities unambiguously reduces welfare. If, however, tax-setting authorities pursue revenue maximization, fragmentation, by pushing down equilibrium tax rates, may under certain conditions increase citizen welfare. We exploit the highly decentralized and heterogeneous Swiss fiscal system as a laboratory for the estimation of these effects. While for purely direct-democratic jurisdictions (which we associate with benevolent tax setting) we find that tax rates increase in fragmentation, fragmentation has a moderating effect on the tax rates of jurisdictions with some degree of delegated government. Our results thereby support the view that tax competition can be second-best welfare enhancing by constraining the scope for public-sector revenue maximization.tax competition; optimal taxation; government preferences; fiscal federalism; direct democracy

Pension Benefit Insurance and Pension Plan Portfolio Choice

Pension benefit guarantee policies have been introduced in several countries to protect private pension plan members from the loss of income that would occur if a plan was underfunded when the sponsoring firm terminates a plan. Most of these public insurance schemes face financial difficulty and consequently policy reforms are being discussed or implemented. Economic theory suggests that such schemes will face moral hazard and adverse selection problems. In this note we test a specific theoretical prediction -- insured plans will invest more heavily in risky assets. Our test exploits differences in insurance arrangements across Canadian jurisdictions. We find that insured plans invest about 5 percent more in equities than do similar plans without benefit guarantees.Pensions, benefit guarantee, moral hazard

Vertical Versus Horizontal Tax Externalities: An Empirical Test

We study taxation externalities in federations of benevolent governments. Where different hierarchical government levels tax the same base, one can observe two types of externalities: a horizontal externality, working among governments of the same level and leading to tax rates that are too low compared to the social optimum; and a vertical externality, working between different levels of government and leading to suboptimally high tax rates. Building on the model of Keen and Kotsogiannis (2002), we derive a discriminating hypothesis to distinguish vertical and horizontal tax externalities based on measurable variables. This test is applied to a panel data set on local taxes in a sample of Swiss municipalities that feature direct-democratic fiscal decision making, so as to maximize the correspondence with the "benevolent" governments of the theory. We find that vertical externalities dominate - they are thus an observed empirical phenomenon as well as a notable extension to the theory of tax competition.

Electoral Competition as a Determinant of Fiscal Decentralization

Fiscal decentralization is high on the agenda in policy fora. This paper empirically investigates the underlying causes of Â…fiscal decentralization, based on the predictions of a simple political economy model. We argue that the likeliness that a central government engages in devolution of powers depends in important ways on the political forces that it faces, the theoryÂ’'s main insight being that the central governmentÂ’'s electoral strength should, all else being equal, decrease that governmentÂ’'s share of spending. Consistent with the model'Â’s predictions, empirical results from a panel of democracies support the relevance of political factors as determinants of fiÂ…scal decentralization. The relationship between central government electoral strength and both expenditure and revenue centralization emerges as negative and non-linear.Fiscal decentralization; Fiscal federalism; Vertical interactions; Partial Decentralization; Elections
