This paper provides an analysis of exclusive contracts between health care providers and insurers in a model where some consumers choose to stay uninsured. In case of a monopoly insurer, exclusion of a provider changes the distribution of consumers who choose not to insure. Although the...

This paper explores the future of unemployment insurance in the Netherlands against the background of various social and economic trends. It starts by discussing the literature on optimal unemployment insurance. This aims to demonstrate the key trade-offs that the government faces in designing...

In this paper, the authors study optimal risk adjustment in imperfectly competitive health insurance markets when high-risk consumers are less likely to switch insurer than low-risk consumers.<font face="CMR10" size="3"><font face="CMR10" size="3">First, they find that insurers still have an incentive to select even if risk adjustment perfectly...</font></font>

We examine vertical integration and exclusive vertical restraints in health-care markets where insurers and hospitals bilaterally bargain over contracts. We employ a bargaining model in a concentrated health-care market of two hospitals and two health insurers competing on premiums. Without...

The total pension premium rate consists of two components, the contribution rate and the catching-up premium rate. The contribution rate finances the accrual of pension rights while the catching-up premium finances (possible) wealth deficits of a pension fund. The contribution rate and the...

To answer policy questions that have intergenerational implications, a computable simulation model should obey four conditions, it should: incorporate long-term demographic developments; include a detailed modelling of the public sector; decompose the population into several generations; account...

In this paper, we estimate the degree of substitution between enrolment into Disability Insurance (DI) and Unemployment Insurance (UI) in the Netherlands. Starting in the 1990s many policy measures aimed at reducing DI enrolment, and increase labour force participation. We quantify whether...

In this paper, we construct and estimate a (semi-) structural model, so as to uncover the fraction of hidden unemployment in the Disability Insurance (DI) enrolment rate. For this purpose, we use longitudinal administrative data of Dutch employers for 1994-2003. We find the (average) fraction...

In light of the ageing of the Dutch society, policy measures aim at increasing the participation rate of elderly workers, particularly in the age-group between 55 and 64. This paper develops a stylized numerical simulation model. This model describes consumption, savings and labour supply...

Intergenerational risk sharing by funded pension schemes may increase welfare in an ex ante sense. However, it also suffers from a time inconsistency problem. In particular, young generations may be unwilling to start participating in a pension scheme if this requires them to make huge transfers...
