This paper finds that it is optimal to start a long-term emission-reduction strategy with significant short-term abatement investment, even if the optimal carbon price starts low and grows progressively over time. Moreover, optimal marginal abatement investment costs differ across sectors of the...

Business cycles are costlier and stabilization policies more beneficial than widely thought. This paper shows that all business cycles are asymmetric and resemble mini "disasters." By this we mean that growth is pervasively fat-tailed and non-Gaussian. Using long-run historical data, we show...

The author investigates the welfare cost of business cycles in an economy where households have heterogeneous trading technologies. In an economy with aggregate risk, the different portfolio choices induced by heterogeneous trading technologies lead to a larger consumption inequality in...

Hours volatility has changed non-monotonically across skill groups since the mid-1980s. This study researches the implications of such changes on the welfare costs of business cycles. Using a partial equilibrium model in which hours fluctuations are the only source of uncertainty, we find that...

How can we measure the welfare benefit of ongoing stabilization policies? We develop a methodology to calculate the welfare cost of business cycles taking into account that observed consumption is partially smoothed. We propose a decomposition that disentangles consumption in a mix of...

Economic fluctuations are much stronger in developing countries than in the United States. Yet, while a large literature debates what constitutes a reasonable estimate of the welfare cost of business cycles in the US, it remains an open question how large that cost is in developing countries....

Extant estimates of the welfare cost of business cycles suggest that this cost is quite low and might well be minuscule. Those estimates are based on consumption data for the United States as a whole. The volatility of aggregate consumption, however, is much stronger at the state level. We argue...

Macroeconomic fluctuations are much stronger in developing countries than in the United States. Yet, while a large literature debates the welfare cost of economic fluctuations in the US, it remains an open question how large that cost is in developing countries. Using several models, we provide...

I investigate the welfare cost of business cycles due to asymmetries generated by two occasionally binding constraints (OBCs): downward nominal wage rigidity (DNWR) and zero lower bound (ZLB). Although business cycle volatility has declined recently as the Great Moderation literature suggests, I...
