The sustainability of a defined benefit pay-as-you-go (DBPAYG) pension system is investigated in the context of an overlapping-generations model of endogenous fertility with heterogeneous agents. The model places particular emphasis on the time costs of child rearing. It illustrates the...

Welfare comparisons between funded and pay-as-you-go (PAYG) pension systems are often made using the Aaron condition. However, the Aaron condition as usually stated is not precise enough about the exact form of the PAYG pension system. PAYG pension systems can be either of the defined-benefit or...

Three theoretical benchmark models of diffusion of new technologies are the substitution, mortality and social-learning models. These models tend to generate symmetric, right-skewed and left-skewed S-curves respectively. The empirical literature has focused primarily on fitting either Logistic...

The treatment of owner-occupied housing (OOH) is probably the most important unresolved issue in inflation measurement. The European Union has been grappling with this problem for over a decade. We argue for measuring OOH costs using a particular version of the user cost method. We then compare...
