This paper explores the general-equilibrium impact of social security portfolio diversiŽ cation into private securities, either through the trust fund or private accounts. The analysis depends critically on heterogeneities in saving, production, assets, and taxes. Limited diversiŽcation weakly increases interest rates, reduces the expected return on short-term investment (and the equity premium...

A Constitutional Theory of the Family The paper re-examines the idea that a family can be viewed as a community governed by a self-enforcing constitution, and extends existing results in two directions. First, it identifies circumstances in which a constitution is renegotiation-proof. Second, it introduces parental altruism. The behavioural and policy implications are illustrated by showing the...

This paper presents results from an impact analysis of the Ticket to Work (TTW) program, as implemented by the Social Security Administration (SSA) from 2002 through 2007. For new, young Social Security Disability beneficiaries, we use exogenous variation in the month of Ticket mailing to rigorously estimate impacts of TTW on beneficiary outcomes over a 48-month period following the start of Ti...

Health Status, Disability and Retirement Incentives in Belgium Many Belgian retire well before the statutory retirement age. Numerous exit routes from the labor force can be identified: old-age pensions, conventional early retirement, disability insurance, and unemployment insurance are the most prominent ones. We analyze the retirement decision of Belgian workers adopting an option value frame...

This report describes the organisation of the Belgian long-term care system. It can be characterised as a mixed system, with extensive public care provision and the substantial support of informal care provided mainly within the family. While the current volume and quality of services appears to be adequate, the future increase in the number of dependent elderly persons over the next two decade...

This paper studies human capital formation, labor supply and retirement decisions associated with four alternative regimes of social security. We implement a theoretical model with overlapping generations of households and two different ability types within each generation. We find that with a given social security contribution rate, it is better to transfer income to the elderly as old-age ben...

Social Insurance Networks Based on administrative panel data from Norway, we examine how social insurance dependency spreads within neighborhoods, families, ethnic minorities, and among former schoolmates. We use a fixed effects methodology that accounts for endogenous group formation, contextual interactions, and time-constant as well as time-varying confounders. We report evidence that social...

This paper opens a new perspective from which one can explain the presence of government intervention in education even in the absence of human capital externality. It argues that consumption externalities can provide rationale for government intervention in education. Within the context of overlapping generations economy, it has also been shown that competitive equilibrium either underaccumula...

Sediment mass-balance analysis provides key constraints on stratigraphic architecture and its controls. We use the data-rich Middle Jurassic Brent Delta sediment routing system in proto-Viking Graben, Northern North Sea, to estimate budgets between source areas depositional sinks. Published studies are synthesised provide an age-constrained sequence framework, consisting of four previously defi...

High Performance Workplaces and Family Friendly Practices: Promises Made and Promises Kept * High performance workplaces elicit greater involvement and productivity from employees but past theory and evidence remain divided on whether or not such workplaces are compatible with family friendly work practices. We present new evidence on the association using perceptions of a representative sample...
