This paper studies an economy where agents can spend resources on consuming a private good and on funding a public good. There is asymmetric information regarding agents' relative preference for private versus public good consumption. I show how private good consumption should be coordinated...

This paper proposes and analyzes a model of a European economy with three overlapping generations, redistributive social security, and public universities without tuition. Individuals differ ex ante. The effect of wage tax rate on occupational choice and the voting equilibrium of wage tax rate...

We analyze optimal taxation of labor and capital income in a life-cycle framework with idiosyncratic income risk. We provide a novel decomposition of labor income tax formulas into a redistribution and an insurance component. The latter is independent of the social welfare function and...

Greenhouse gas policies confront the trade-off between the costs of reducing emissions and the benefits of avoided climate change. The risk of uncertain and potentially irreversible catastrophes is an important issue related to the latter, and one that has not yet been well incorporated into...

We consider environmental regulation in a context where firms invest in abatement technology under conditions of uncertainty about subsequent abatement cost, but can subsequently adjust output in the light of true marginal abatement cost. Where an emission tax is the only available instrument,...

This paper analyses second-best optimal environmental policies in the presence of a double dividend. Using a partial equilibrium model, the paper first reconfirms the well-known result that the existence of a double dividend (in its weak form) favours environmental policy instruments which -...

In this paper, we consider a problem in environmental policy design by applying optimal stopping rules. The purpose of this paper is to analyze the optimal timings at which the government should adopt environmental policies to deal with increases in greenhouse gas concentrations and to reduce...

We analyse optimal abatement and carbon pricing strategies under a variety of economic, temperature and damage risks. Economic growth, convex damages and temperature-dependent risks of climatic tipping points lead to higher growth rates, but gradual resolution of uncertainty lowers them. For...

We study the optimal taxation of risk-free and excess capital income with heterogeneous rates of return, alongside an optimal nonlinear earnings tax. Households can hold three assets: one risk-free, one risky but diversifiable, and one a private investment with idiosyncratic risk whose expected...

We analyse optimal abatement and carbon pricing strategies under a variety of economic, temperature and damage risks. Economic growth, convex damages and temperature-dependent risks of climatic tipping points lead to higher growth rates of carbon prices, but gradual resolution of uncertainty...
