We study the welfare effects of disability insurance (DI) and derive social-optimality conditions for the two main DI policy parameters: (i) DI eligibility rules and (ii) DI benefits. Causal evidence from two DI reforms in Austria generate fiscal multipliers (total over mechanical cost...

Most countries reduce Disability Insurance (DI) benefits for beneficiaries earning above a specified threshold. Such an earnings threshold generates a discontinuous increase in tax liability - a notch - and creates an incentive to keep earnings below the threshold. Exploiting such a notch in...

There exists a wide variety of tax treatments of pensions across the world. And the reasons for such a range of regimes are not clear. This note reviews the general principles of pension taxes and analyses the theoretical foundations of why pension incomes ought to be taxed specifically. To do...

A key component for estimating the optimal size and structure of disability insurance (DI) programs is the elasticity of DI claiming with respect to benefit generosity. Yet, in many countries, including the United States, all workers face identical benefit schedules, which are a function of...

We exploit a unique Swiss reform to identify the importance of passivity, claiming social security benefits at the Full Retirement Age (FRA). Sharp discontinuities generated by the reform reveal that raising the FRA while imposing small early claiming penalties significantly delays pension...

Disability insurance (DI) beneficiaries lose part of their benefits if their earnings exceed certain thresholds ("cash-cliffs"). This implicit taxation is considered the prime reason for low DI outflow. We analyse a conditional cash program that incentivises work related reductions of disability...

We study the design of pension benefits for male and female workers. Women live longer than men but have a lower wage. Individuals can be single or live in couples who pool their incomes. Social welfare is utilitarian but an increasing concave transformation of individuals' lifetime utilities...

We study the role and design of private and public insurance programs when informal care is uncertain. Children's degree of altruism is randomly distributed over some interval. Social insurance helps parents who receive a low level of care, but it comes at the cost of crowding out informal care....

We study the design of public long-term care (LTC) insurance when the altruism of informal caregivers is uncertain. We consider non-linear policies where the LTC benefit depends on the level of informal care, which is assumed to be observable while children's altruism is not. The traditional...
