Quantifying factors giving rise to temporal variation in forest fires is important for advancing scientific understanding and improving fire prevention. We demonstrate that eighty percent of the large year-to-year variation in forest area burned in California can be accounted for by variation in...

We study climate change in a model with a carbon-intensive and a green sector, each subject to stochastic sectoral productivity shocks, and show how the underlying economic structure affects the risk-adjusted discount rate and the climate risk premium in the social cost of carbon (SCC)....

We investigate externalities in higher education enrollment over the course of development in a two-sector model. Each sector works with only one type of labor, skilled or unskilled, and individuals are differentiated according to their cost of acquiring human capital. Both sectors exhibit...

Pay-as-you-go (PAYG) social security schemes in the OECD countries are facing solvency problems, as people are living longer and birth rates have declined. Postponing the full retirement age (FRA), when retirees are entitled to full pension, has been proposed as a solution. This effectively...

How should central banks optimally aggregate sectoral inflation rates in the presence of imperfect labor mobility across sectors? We study this issue in a two-sector New-Keynesian model and show that a lower degree of sectoral labor mobility, ceteris paribus, increases the optimal weight on...

In this paper we derive a microfounded macro New Keynesian model for open economies, be they large or small. We consider habit formation in consumption, sectoral linkages for tradable and non-tradable goods, capital stock investments with variable capital utilization, domestic and foreign...

We develop a two-country, two-sector model of trade where the only difference between the two countries is their distribution of human capital endowments. We show that even if the two countries have identical aggregate human capital endowments the pattern of trade depends on the properties of...

We analyze optimal taxation of labor and capital income in a life-cycle framework with idiosyncratic income risk. We provide a novel decomposition of labor income tax formulas into a redistribution and an insurance component. The latter is independent of the social welfare function and...

The total social benefits of college education exceed the private benefits because the government receives a share of the monetary returns in the form of income taxes. We study the policy implications of this fiscal externality in an optimal dynamic tax framework. Using a variational approach we...

We study implications of habit formation for optimal taxation. First, we show that taxation problems with habit formation can be analyzed using dynamic programming techniques. Second, we derive optimal labor and savings wedges for habit formation preferences. We show that habit formation...
