This paper estimates demand for residential solar photovoltaic (PV) systems using a new approach to address three empirical challenges that often arise with count data: excess zeros, unobserved heterogeneity, and endogeneity of price. Our results imply a price elasticity of demand for solar PV...

This paper studies how subsidies for solar systems can lead to second-degree moral hazard - the impulse of installers to increase prices and/or reduce labor input when customers receive subsidies. Employing an instrumental variable strategy using plausibly exogenous variation in the size of...
