Thinking versus Doing: Cognitive Capacity, Decision Making and Medical Diagnosis
We study impact of situational factors on decision making of physicians. Using detailed audit log data from emergency rooms, we access how cognitive load during the shift affects future choices of tests as well as the treatment. We draw upon theories of information acquisition to infer how much is physicians' knowledge refined when making a particular choice. For instance, we find that high cognitive load implies that physicians make less informed choices in the future, perhaps choose to think less, and instead substitute this with more orders of diagnostic tests.

Diversified Production and Market Power: Theory and Evidence from Renewables
écrit avec Co-authors: Michele Fioretti and Jorge Tamayo
We show that market power can either exacerbate or mitigate fluctuations in energy prices due to renewable energy availability and provide empirical evidence from the Colombian energy sector, where hydropower generation is prevalent and energy suppliers have a diversified technology portfolio. Incentives to crowding-out rivals make a supplier produce more during a drought if it has access to other technologies with capacities unaffected by the drought. During abundance, instead, access to other technologies reduces a firm’s supply compared to a scenario where these technologies are owned by its rivals, as rivals cannot crowd-out the firm experiencing abundance as easily. Jointly, these two effects create a U-shaped relationship between market concentration and prices when firms have diversified production technologies, which applies more broadly to other industries. Initially, transferring high-cost capacity to a large firm with the most efficient technology lowers prices,
but eventually leads to unilateral price increases.

*A Welfare Analysis of Policies Impacting Climate Change
What are the most effective ways to address climate change? This paper extends and applies the marginal value of public funds (MVPF) framework to help answer this question. We examine around 100 US environmental policy changes studied over the past 25 years. These policies span subsidies (wind, residential solar, electric and hybrid vehicles, vehicle replacement, appliance rebates, weatherization), nudges (marketing and energy conservation), and revenue raisers (fuel taxes, cap and trade). For each policy, we draw upon quasi-experimental or experimental evaluations of causal effects, and translate those estimates into an MVPF. We apply a consistent translation of these behavioral responses into measures of their associated externalities and valuations of those externalities. We also provide a new method for incorporating learning-by-doing spillovers. We then contrast the conclusions from the policy categories with those derived from more traditional cost per ton metrics used in previous literature.
