We consider a Green Public Procurement setting where the procurer provides a bid discount to environment-friendly technologies to foster their use. We assume that, before the auction, firms may switch to green technology via a publicly observable costly investment. We show that investment acts as a signaling device. This mitigates the effect of incomplete information on firms’ costs, thereby triggering ...
Using machine learning methods in a quasi-experimental setting, I study the heterogeneous effects of introducing waste prices - unit prices on household unsorted waste disposal - on waste demands and social welfare. First, using a unique panel of Italian municipalities with large variation in prices and observables, I show that waste demands are nonlinear. - find evidence of constant elasticities at ...
We examine the impact of a disclosure mandate for greenhouse gas emissions on firms’ subsequent emission levels and financial operating performance. For UK-incorporated listed firms a carbon disclosure mandate was adopted in 2013. Our difference-in-differences design shows that firms affected by the mandate reduced their emissions by about 8% relative to a control group of European firms. At the same ...
This paper tests the independence property under the Coase Theorem in a large multinational cap-and-trade scheme for greenhouse gas emissions, the EU Emissions Trading System (EU ETS). I analyze whether emissions of power producers regulated under the EU ETS are independent from allowance allocations, leveraging a change in allocation policy for a difference-in-differences strategy. The evidence suggests ...
