Among Brazil's gasoline-ethanol vehicle users, it is common to observe the purchase of the fuel that yields the less miles per dollar of spending. In a large-scale set of experiments with 10,400 subjects, I inform energy consumers at the pump of the effective price difference across fuels. The...

This study examines attention effects in the market for hybrid vehicles. We show that local media coverage, gasoline price changes and unprecedented record gasoline prices have a significant causal impact on the consumers' attention. As attention is not directly observable, we analyze online...

There is an ongoing debate in the literature about whether consumers are fully informed when investing in energy efficiency. We experimentally evaluate the role of imperfect information or limited attention about energy costs of home appliances and light bulbs on households' choices. Using...

We conduct a large scale randomized field experiment to study whether providing recipients - 42,454 Chinese households in a rural area - with information on the costs of a real decision they make can help to improve the quality of their choices. The decisions are of high financial impact, as the...

There is an ongoing debate in the literature about whether consumers are fully informed when investing in energy efficiency. We experimentally evaluate the role of imperfect information or limited attention about energy costs of home appliances and light bulbs on households' choices. Using...

We conduct a field experiment on a movie-recommendation platform to identify if and how recommendations affect consumption. We use within-consumer randomization at the good level and elicit beliefs about unconsumed goods to disentangle exposure from informational effects. We find recommendations...

I study consumers' choices in the retail electricity market. By conducting a largescale survey experiment with 3% of the Danish working-age population, I have gathered data on respondents' factual knowledge of the retail electricity market, their beliefs, preferences, and intentions to switch...

As much as forty percent of social media users have been harassed online, but there is scarce causal evidence of how toxic content impacts user engagement and whether it is contagious. In a pre-registered field experiment, we recruited participants to install a browser extension, and randomly...

Interventions to decrease meat consumption are often only implemented for short periods of time, and it is unclear how they might have lasting effects. We combine student canteen consumption (over 270, 000 purchases made by over 4, 500 guests) and survey data (N 800) to study how a one-month...

This paper presents new evidence on the question: Why don’t consumers switch electricity contracts? By conducting a large-scale survey experiment with 3% of the Danish working-age population, I have gathered data on respondents’ factual knowledge of the retail electricity market, their...
