We study a large economy model in which individuals have private information about their productive abilities and their preferences. Moreover, there is aggregate uncertainty so that the social benefits from taxation and public goods provision are a priori unknown. The analysis is based on a...

Climate is a persistent asset, bar none: changes in climate-related stocks have consequences spanning over centuries or possibly millennia to the future. To reconcile the discounting of such far-distant impacts and realism of the shorter-term decisions, we consider hyperbolic time-preferences in...

There are many reasons to suspect that benefit-cost analysis applied to environmental policies will result in policy decisions that will reject those environmental policies. The important question, of course, is whether those rejections are based on proper science. The present paper explores...

World income grows fast without verifiable climate-change impacts on the economy. The growth spell can end if climate impacts turn real but this can take decades to learn. We develop a tractable stochastic climate-economy model with a hidden-state impact process to evaluate the contributions of...

Should public assets such as infrastructure, education, and the environment earn the same return as private investments? We consider if time-inconsistent decision-makers can gain from institutions that enforce cost-benefit rules on large projects that influence the economy as a whole. Long-term...

This paper studies the determination of informal long-term care (family aid) to dependent elderly in a worst case scenario concerning the “harmony” of family relations. Children are purely selfish, and neither side can make credible commitments (which rules out efficient bargaining). The...

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...

We study implications of habit formation for optimal taxation. First, we show that taxation problems with habit formation can be analyzed using dynamic programming techniques. Second, we derive optimal labor and savings wedges for habit formation preferences. We show that habit formation...

This paper examines the question of achieving a societal consensus around redistributive policies. Its extent is measured by the degree of work participation among the different skill classes that populate the economy. This consensus is driven both by the material incentives and heterogeneous...

Adaptation is omnipresent but people systematically fail to correctly anticipate the degree to which they adapt. This leads individuals to make inefficient intertemporal decisions. This paper concerns optimal income taxation to correct for such anticipation-biases in a framework where consumers...
