Climate policy feasibility across Europe relies on the conditional middle
Unraveling Ambiguity Aversion
We report the results of two experiments designed to better understand the mechanisms driving decision making under ambiguity. We elicit individual preferences over different sources of uncertainty, entailing different degrees of complexity, from subjects with different sophistication levels. We show that (1) ambiguity aversion is robust to sophistication, but the strong relationship previously reported between attitudes toward ambiguity and comp…
Beliefs about EU 2030 climate commitments across public, expert, and policy audiences
The European Union (EU) has adopted ambitious climate policies to reduce greenhouse gas emissions by 55% by 2030. While technical, economic, and political feasibility have been widely analyzed, far less is known about a critical enabling factor: whether key societal actors perceive these targets as credible and achievable. In this study, we elicit probabilistic beliefs about future EU emission reductions from a sample of citizens designed to be r…
The limits of behavioral nudges to increase youth turnout
There is a significant gap in turnout between young people and older voters. The failure to instill a voting habit at an early age may have long term consequences in terms of future political participation as well as on other civic behaviors. Using a pre-registered online experiment with 3790 subjects, we implemented behavioral interventions aiming to stimulate youth turnout in the 2022 French presidential election. We rely on an innovative incen…
The Limits of Behavioral Nudges to Increase Youth Turnout
Pay all subjects or pay only some? An experiment on decision-making under risk and ambiguity
We investigate the validity of a double random incentive system where only a subset of subjects is paid for one of their choices. By focusing on individual decision-making under risk and ambiguity, we show that using either a standard random incentive system, where all subjects are paid, or a double random system, where only 10% of subjects are paid, yields similar preference elicitation results. These findings suggest that adopting a double rand…
What is partial ambiguity
This paper reflects on the notion of partial ambiguity. Using a framework decomposing ambiguity into distinct layers of analysis, among which are risk and model uncertainty , and allowing for different attitudes toward these layers, I show that partial ambiguity may prove less desirable than full ambiguity, even under ambiguity aversion. This observation poses difficulties for interpreting the notion of partial ambiguity in relation to the partia…
Are Policymakers Ambiguity Averse
We investigate the ambiguity preferences of a unique sample of real-life policymakers at the Paris UN climate conference (COP21). We find that policymakers are generally ambiguity averse. Using a simple design, we are moreover able to show that these preferences are not necessarily due to an irrational behavior, but rather to intrinsic preferences over unknown probabilities. Exploring the heterogeneity within our sample, we also show that the cou…
