This paper presents the properties of optimal piecewise linear tax systems for two-earner households, based on joint and individual incomes respectively. A key contribution is the analysis of the interaction between second earner wage differences, variation in the price of child care and...

Given that young children are under the control of their parents, if the government has an interest in either the welfare or the productivity of the former, it has no option but to act through the latter. Parents are, in the ordinary sense of the word, the government’s agents. They are agents...

We analyze whether a redistributive government should provide ex ante insurance against unfortunate outcomes or whether it should instead rely on transfers for redistributing income ex post. To this end, we develop a model of education in which individuals face educational risk and wage...

This paper presents the case for tax progressivity based on recent results in optimal tax theory. We consider the optimal progressivity of earnings taxation and whether capital income should be taxed. We critically discuss the academic research on these topics and when and how the results can be...

We study the dynamic Ramsey problem of finding optimal public debt and linear taxes on capital and labor income within a tractable infinite horizon model with incomplete markets. With zero public expenditure and debt, it is optimal to tax the risky labor income and subsidize capital, while a...

This paper examines whether myopia (misperception of the long-term care (LTC) risk) and private insurance market loading costs can justify social LTC insurance and/or the subsidization of private insurance. We use a two-period model wherein individuals differ in three unobservable...

We study the optimal tax system in a dynamic model where differences in wages induce differences in inheritances, and the transition from parent ability to child ability is described by a Markov chain. We characterize expected inheritances in the steady state and show that the Atkinson-Stiglitz...

This paper proposes a theory of commodity taxation in the presence of durable goods. Optimal commodity taxes depend on preference nonseparabilities between durable and nondurable consumption. In particular, the seminal Atkinson–Stigliz result fails and differential commodity taxes are optimal...

Justification for policies to encourage investments in education, particularly for individuals at the lower end of the ability distribution, may be provided by behavioural economics. We present a prototypical model where individuals who are potentially loss averse around their expected outcome...

The paper characterizes the optimal tax policy and the optimal quality of day care services in a OLG model with warm-glow altruism where parental choices over child care arrangements affect the probability that the child becomes a high-skilled adult in a type-specific way. With respect to...
