"Substantial evidence suggests that savings behavior may depart from neoclassical optimization. This article examines the implications of raising the savings rate - whether through social security, retirement plans, or otherwise - for labor supply, where labor supply is determined by behavioral utility functions that reflect the non-neoclassical character of savings behavior. Under one formulation, raising the targeted savings rate has the same effect on labor supply as that of raising the labor income tax rate; under a second, raising the targeted savings rate has no effect on labor supply; and under a third, raising the targeted savings rate increases labor supply regardless of the slope of the labor supply curve. Effects on labor supply are particularly consequential because of the significant preexisting distortion due to labor income taxation"--National Bureau of Economic Research web site

"This essay revisits the question of instrument choice for the regulation of externalities in the context of climate change. The central point is that the Pigouvian prescription to equate marginal control costs with the expected marginal benefits of damage reduction should guide the design of both carbon taxes and permit schemes. Because expected marginal damage rises nonlinearly, a corresponding nonlinear tax - or an equivalent price implemented through a quantity-adjusted permit scheme - is second best. Also considered are political factors, distinctive features of regulating a stock pollutant, and ex ante distortions due to the anticipation of transition relief (such as by receiving more free permits for greater emissions). Finally, distributive concerns are examined, with emphasis on the conceptual and practical benefits of addressing distributive issues with the tax and transfer system rather through adjustments to regulatory schemes that usually render them less effective"--National Bureau of Economic Research web site

"Optimal policy rules--including those regarding income taxation, commodity taxation, public goods, and externalities--are typically derived in models with homogeneous preferences. This article reconsiders many central results for the case in which preferences for commodities, public goods, and externalities are heterogeneous. When preference differences are observable, standard second-best results in basic settings are unaffected, except those for the optimal income tax. Optimal levels of income taxation may be higher, the same, or lower on types who derive more utility from various goods, depending on the nature of preference differences and the concavity of the social welfare function. When preference differences are unobservable, all policy rules may change. The determinants of even the direction of optimal rule adjustments are many and subtle"--National Bureau of Economic Research web site
