Solar geoengineering (SGE) can combat climate change by directly reducing temperatures. Both SGE and the climate itself are surrounded by great uncertainties. Implementing SGE affects learning about these uncertainties. We model endogenous learning over two uncertainties: the sensitivity of...

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...

This paper presents a dynamic model of political competition between two "parties" with different policy preferences. A "party" is explicitly modeled as a sequence of overlapping generations of candidates, all of whom face finite decision horizons. In general, there is a conflict between the...
