The pay-as-you-go pension system as fertility insurance and an enforcement device

A PAYGO system may serve as insurance against not having children and as an enforcement device for ungrateful children who are unwilling to pay their parents a pension. In fact, the latter was Bismarck’s historic motive for introducing this system. It is true that the PAYGO system reduces the investment in human capital, but if it is run on a sufficiently small scale, it may nevertheless bring about a welfare improvement. If, on the other hand, the scale of the system is so large that parents bequeath some of their pensions to their children, it is overdrawn and creates unnecessarily strong disincentives for human capital investment

Tax Harmonization and Tax Competition in Europe

Opening Europe's borders in 1993 makes the allocation of resources more vulnerable to differences in the national tax rates. The first part of the paper demonstrates that direct consumer purchases will imply distortions resulting from diverging VAT rates and it clarifies why the frequently cited exchange rate argument is of no help. The second part shows that, in the case of direct taxation, a harmonization of tax bases is more important than a harmonization of tax rates. Either the combination of true economic depreciation and residence taxation or the combination of immediate write-off and source taxation will result in an efficient international allocation of capital, independent of the national tax rates. The paper concludes with a verdict on tax competition arguing that free migration renders a policy of income redistribution, which is interpreted as insurance against the risk of lifetime careers, impossible.

The Crisis of Germany's Pension Insurance System and How It Can Be Resolved

The paper discusses the options for a reform of the German pension system using a model developed at CES for the German Council of economic advisors to the Federal Ministry of Economics and Research. It is argued that the German pay-as-you-go-system is efficient in a present value sense but will nevertheless need the support of a funded system to avoid a financial crisis. The paper investigates the possibility of introducing obligatory private savings at a variable rate where the time path of the savings rate is chosen so as to stabilize the sum of this rate and the pay-as-you-go contribution rate, given the time path of pensions as defined in the present system.

The Vanishing Harberger Triangle

The paper presents a trapped equity model, but instead of studying how taxes affect corporate decisions when a sufficient amount of equity is already in the trap, it asks the question how does the equity get there. To be more specific, the paper analyzes how the double taxation of dividends affects the growth of a corporation that starts with no equity capital. One conclusion is that dividend taxes are distortionary before they are paid, but not when they are paid. Once the firm is in a stage of maturity where it pays dividends and dividend taxes, tax neutrality prevails. Thus the true intersectoral distortion resulting from corporate taxation is negatively correlated with the measured tax burden, and it is lower, the higher the distortion which estimates of Harberger type would predict. Another conclusion is that the King-Fullerton cost of capital formulae are not applicable in the case of immature firms. These formulas are based on the assumption that firms distribute their profits from marginal investment projects as dividends. However, immature firms strictly prefer a reinvestment to a distribution of profits. The reinvestment changes the cost of equity capital, and typically this cost is higher than a hasty application of the King-Fullerton formulas would predict.

The Welfare State and the Forces of Globalization

The emergence of the Asian tiger countries and the participation of the ex-communist countries in world trade has reduced the equilibrium price of labor in western Europe and elsewhere. However, the actual price of labor hardly reacts, because the welfare state's minimum replacement incomes are fixed. The rigidity of wages causes pathological overreactions of the European economy in terms of excessive capital exports, excessive immigration and excessive structural change towards the capital intensive export sectors. The overreactions cause unemployment, sluggish growth, a current account surplus and a high export volume, but may prevent gains from trade. Moving from a system of wage replacement incomes to one that pays wage subsidies would enable a more efficient economic reaction that would not jeopardize social goals but bring about more employment, growth and gains from trade.
