Background: In its pursuance of universal health coverage (UHC), the government of Benin is piloting a project of mandatory social insurance for health entitled "ARCH". Methods: We analysed budget data and ARCH documents, and conducted four observation missions in Benin between March 2018 and...

This paper examines the benefits of supplemental pension plans by comparing the costs and benefits, in terms of equity, of public retirement plans and private plans in OECD member countries, particularly focusing on the income distribution of the elderly.

This paper focuses on the effect ageing has on intragenerational equity in seven LIS countries. Using current distribution schemes as baselines, the authors compare the projected effects of four benefit scenarios on aged inequality.

The study of optimal long-term care (LTC) social insurance is generally carried out under the utilitarian social criterion, which penalizes individuals who have a lower capacity to convert resources into well-being, such as dependent elderly individuals or prematurely dead individuals. This...

An overlapping generations models is constructed in which individual wealth is related to educational attainment, and in which liquidity constraints may induce children to invest in a sub-optimal level of education given their ability. Borrowing for educational attainment is obtained from within...

Despite the fact that all developed economies levy broadly-based indirect taxes alongside direct taxes, little theory is devoted to explaining the direct-indirect tax mix. Our purpose is to show that if different taxes have different evasion characteristics, some optimal tax mix emerges...

This paper studies optimal linear income taxation and redistributive social insurance when the former has the traditional labor distortion and the latter generates both ex ante and ex post moral hazard. Private insurance is available and individuals differ in labor productivity and in loss...

The Atkinson-Stiglitz Theorem states that if labor is weakly separable from goods in household utility functions, differential commodity taxation should not be not part of an optimal redistributive tax system. This Theorem, which is arguable the most policy-relevant result to come out of the...

We study the optimal redistributive tax structure when the population can be disaggregated into tagged groups. We begin with the case in which the tag has no normative significance, but simply separates the population into identifiable groups with different distributions of ability-types. Under...
