Passenger transport has significant externalities, including carbon emissions and air pollution. Public health research has identified additional social gains from active travel, due to the health benefits of physical exercise. Per mile, these benefits greatly exceed the external costs from car...

Financing productive public capital through distortionary taxes typically creates a trade-off: the optimal investment is determined as a compromise between efficiency-enhancing public investment and perturbing market efficiency, but is never socially optimal. In contrast, such a trade-off can...

Carbon-pricing initiatives are spreading at an unprecedented rate, but a considerable gap remains between actual prices and those required to achieve ambitious climate change mitigation. This perspective shows that much of this gap could be closed by enhancing the public’s acceptance of carbon...

This letter analyzes the distributional effects of a carbon tax reform when households must consume carbon-intensive goods above a subsistence level. The reform is progressive if revenues are recycled as uniform lump-sum transfers, in other cases it is regressive.

Imperfect altruism between generations may lead to insufficient capital accumulation. We study the welfare consequences of taxing the rent on a fixed production factor, such as land, in this setting. We prove that taxing the rent is welfare-enhancing as it increases capital investment. This...

A major obstacle for introducing carbon pricing are its distributional implications: climate policy is believed to be regressive. We illuminate the role of carbon-intensive subsistence consumption for the prospect of making carbon pricing progressive. The distributional impacts of a carbon tax...

We study the impact of heterogeneous saving behavior on the distributional effects of public investment. A capital tax is levied to finance productive public capital in an economy with two types of households: high income households who save dynastically and middle income households who save for...

We study the trade-off between equity and growth in the context of tax-financed investment in public capital. Taking into account stylized facts on wealth accumulation, we model agent heterogeneity through differences in saving behavior, income source and time preference. In contrast to the...

Carbon pricing regulates emission flows and collects rents from underlying fossil resource stocks. The resulting investment shift implies lower climate policy costs and improved welfare if capital is underaccumulated. We prove that under emission trading, such a beneficial macroeconomic...
