How does risk affect saving? Empirical work typically examines the effects of detectible differences in risk within the … data. How these differences affect saving in theoretical models depends on the metric one uses for risk. For labor …-income risk, second-degree increases in risk require prudence to induce increased saving demand. However, prudence is not …

Recent theoretical work in the economics of climate change has suggested that climate policy is highly sensitive to ‘fat-tailed’ risks of catastrophic outcomes (Weitzman, 2009b). Such risks are suggested to be an inevitable consequence of scientific uncertainty about the effects of increased...

We study the importance of uncertainty and public finance to the welfare ranking of three environmental policy instruments: pollution taxes, pollution permits and Kyoto-like numerical rules for emissions. The setup is the basic stochastic neoclassical growth model augmented with the assumptions...

The paper reexamines the welfare economics of intergenerational risk. Risk and its resolution over time are modeled as … preferences to (i) disentangle aversion to intergenerational inequality from aversion to risk, (ii) exhibit a preference for early … resolution of risk, (iii) show different discounting formulas depending on the magnitude of risk and on the timing of its …

assumption of (intertemporal) risk neutrality reduces the growth effect in social discounting and significantly amplifies the … importance of risk and correlation. Second, debate and models largely overlook the difference in attitude with respect to risk … and with respect to non-risk uncertainty. The paper derives the resulting changes of the risk-free and the stochastic …

the magnitude of the optimal paygo program and the nature of the underlying risk sharing effects are very sensitive to the … chosen combination of risk concepts and stochastic specification of long run aggregate wage income growth. In an additive way … we distinguish between the pooling of wage and capital risks within periods and two different intertemporal risk sharing …

Using the Hamilton-Jacobi-Bellman equation, we derive both a Keynes-Ramsey rule and a closed form solution for an optimal consumption-investment problem with labor income. The utility function is unbounded and uncertainty stems from a Poisson process. Our results can be derived because of the...
