We compare the “degrowth” versus the “decoupling” strategies for carbon abatement, by leveraging the COVID-19 crisis as a natural experiment. Our focus is on the Spanish economy, and in particular, on its power sector. The GDP loss (degrowth) attributable to the pandemic was around 133 Billion Euros, which compared to total emissions reductions (20.4 Million Tons), gives an implicit cost of carbon in the thousands. In turn, power-sector CO2 emissions went down by 3.8 Million Tons (almost 5%). Investing in renewables to achieve similar abatement would have an implicit cost of carbon closer to 90 Euros/Ton.
We asses firms’ incentives to operate and invest in electricity storage facilities under different market structures, including competitive and strategic storage owners in the cases in which the storage owner is integrated with a dominant electricity producer or it is a stand-alone firm. The results are key to understand how to regulate electricity storage, an issue which is critical for the deployment of renewables in electricity markets.
We assess the role of forward contracts and arbitrage in mitigating the market power of dominant producers. This question is particularly relevant for the renewables’ policy debate, as alternative pricing schemes (Feed-in-Tariffs, Feed-in-
We analyse equilibrium bidding behaviour in uniform-price auctions in which each firm’s capacity is stochastic and is private information. We use the model to shed light on the performance of renewables-dominated electricity markets.

“Technology-Neutral versus Technology-Specific Procurement” (with Juan Pablo Montero)
A principal (e.g., a regulator, a firm) needs to procure multiple units of a good or service that can be produced with heterogenous technologies. Should she procure these units by posting separate prices for each technology? Or should she instead procure these units by running technology-specific or technology-neutral auctions? In answering these questions, we identify the trade-offs involved. We show how the answers depend on the nature of the available technologies and the extent of information asymmetry regarding their costs.
“On the Competitive Effects of Retention Strategies”
Retention offers allow firms to price discriminate across consumers with different willingness to switch: prices decrease for those consumers who are more likely to switch, but increase for those who are less likely to switch. In competitive markets, retention offers strengthen competitive pressure. However, if markets are not very competitive, they make them even less so.
