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...

We extend a standard overlapping-generations general-equilibrium model with idiosyncratic working ability shocks to design the optimal social security pension system. There are two main features in our approach. First, we keep track of individual social security wealth explicitly so that we can evaluate a wide range of policies, including “private accounts,” seamlessly. Second, we express our s...

Aging populations are leading countries worldwide to social security reforms. Many countries are moving from pay-as-you-go to personal retirement account (PRA) systems because of their financial sustainability and positive impact on private savings. PRA systems boost private savings at a macro level by converting a government liability into financial wealth managed by private fund managers. How...

The Changing of the Guards: Can Physicians Contain Social Insurance Costs? Based on administrative data from Norway, we examine the extent to which family doctors influence their clients’ propensity to claim sick pay and disability benefits. The analysis is based on exogenous shifts of family doctors occurring when physicians quit, retire, or for other reasons sell their patient lists to other ...

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...

Abstract This study compares the protective effectiveness of Social Safety Nets (SSNs) provided by government and NGOs in rural Pakistan, using quasi-experimental methodology on PRPHS (2011–12) data. The treatment group was households receiving SSNs assistance. counterfactual (control group) determined propensity score matching. Outcome indicators were shock-coping strategies from which are the...

There has long been a minority view that providing people with cash is an effective way of combating poverty and economic insecurity while promoting livelihoods and work. The mainstream view has been that giving people money, without conditions or obligations, promotes idleness and dependency, while being unnecessarily costly. Better, they contend, would be to allocate the available money to sc...

We investigate the dynamic general equilibrium effects of introducing a social assistance program to elderly informal sector workers in developing countries. We find that the extension of such “retirement benefits” in environments with lacking private sector risksharing mechanisms results in welfare increases and relatively minor efficiency losses. Our results suggest that welfare gains attribu...
