A cap on greenhouse gas emissions makes total emissions a fixed common-property resource. Population increases under a cap are therefore self-limiting: a population increase raises labor and reduces emissions per unit of labor, which lowers incomes and fertility. Because a marginal birth under a...

We derive median-voter results and study the shape of redistributional taxes when voters elect a candidate who imposes taxes to maximize own utility. Under general conditions, a median-productivity candidate is a Condorcet winner. The imposed tax function is nonlinear, may place high marginal...

We calculate the harm a birth imposes on others when greenhouse gas emissions are a problem and a cap limits emissions damage. This negative population externality, which equals the corrective Pigovian tax on having a child, is substantial in calibrations. In our base case, the Pigovian tax is...

Yes, subject to concerns about Medicare inefficiencies and potentially self-confirming skepticism. The U.S. social security system-broadly defined to include Medicare-faces significant financial problems as the result of an aging population. But demographic change is also likely to raise...
