We study the relationship between unemployment, environmental policy, and business cycles. We develop a dynamic stochastic general equilibrium real business cycle model that includes both a pollution externality and congestion externalities from labor market search frictions, which generate...

Generational policy is a fundamental aspect of a nation's fiscal affairs. The policy involves redistributing resources across generations and allocating to particular generations the burden of paying the government's bills. This chapter of the second edition of The Handbook of Public Economics...

Finally we question the standard use of infinitely-lived, single-agent models, which assume, unrealistically, intergenerational altruism in determining optimal abatement policy. Their prescriptions can differ, potentially dramatically, from those needed to correct the negative climate...

Will smart machines replace humans like the internal combustion engine replaced horses? If so, can putting people out of work, or at least out of good work, also put the economy out of business? Our model says yes. Under the right conditions, more supply produces, over time, less demand as the...

Government policies that are not intended to address environmental concerns can nonetheless distort prices and affect firms' emissions. We present an analytical general equilibrium model to study the effect of distortionary subsidies on factor prices and on environmental outcomes. We model an...

Fiscal policy in the U.S. and other countries renders intertemporal budgets non-differentiable, nonconvex, and discontinuous. Consequently, assessing work and saving responses to policy requires global optimization. This paper develops the Global Life-Cycle Optimizer (GLO), a stochastic...
