The traditional approach to flexible retirement (e.g. NDC) neglects the impact of asymmetric information on actuarial fairness (neutrality). The mechanism design approach (e.g. Diamond, 2003) gives up the requirement of neutrality and looks for a redistributive second-best benefit-retirement-age...

We fully display a cohort model of an economy with an aging population, taking into account varying family size, habit formation, inheritance and credit constraints. Filling the model with numbers, we are able to compare different pension reforms: 1. the base run, 2. the reduced accrual rates,...

We analyze underreported earnings and age-specific income redistribution in postsocialist economies. Pensions, other transfers and public expenditures are financed from contributions and wage taxes, respectively. We derive the reported earnings and savings from individual utility maximization,...

We analyze the impact of tax morality on progressive income (wage) taxation. We assume that transfers (cash-back) and public expenditures are financed from linear wage taxes. We derive the reported wages from individual utility maximization, when individuals obtain partial satisfaction from...

We analyze the impact of (exogenous) tax morale on the optimal design of progressive income taxation. In our model, only universal basic income (transfer) is financed from a linear income tax and the financing of public goods is neglected. Each individual supplies labor and (un)declares earning,...

In our model, the government operates a mandatory proportional (contributive) pension system to substitute for the low life-cycle savings of the low-paid myopes. The socially optimal contribution rate is high (equalizing young- and old-age consumption for them), while an appropriate cap on...

A child-allowance system is to raise fertility beyond the individual optimum. The more heterogeneous the population with respect to rearing costs, however, the stronger the redistribution and polarization.

van Groezen, Leers and Meijdam (2003) (for short, GLM) analyzed combination of public pension and child support in an OLG model. We impose credit constraint on workers, and extend GLM's analysis from the case where workers do not understand the cost also to the case where they do. GLM's infinite...

In our model, the government operates a mandatory proportional pension system to substitute for the low life-cycle savings of the lower-paid myopes, while maintaining the incentives of the higher-paid, far-sighted in contributing to the system. The introduction of an appropriate cap on pension...
