The behavioral effect of Pigovian regulation: Evidence from a field experiment
2018-1, Lanz, Bruno, Wurlod, Jules, Panzone, Luca, Swanson, Tim
Pigovian regulation provides monetary penalties/rewards to incentivize prosocial behavior, and may thereby trigger behavioral effects beyond a more standard response associated with a change in relative prices. This paper quantifies the magnitude of these behavioral effects using data from an experiment on real product choices together with a structural model of consumer behavior. First, we show that information about external effects (products' embodied carbon emissions) triggers voluntary substitution towards cleaner alternatives, and we estimate that this effect is equivalent to a change in relative prices of GBP30.69-165.15/tCO2. Second, comparing a Pigovian intervention (GBP19/tCO2) with a neutrally-framed price change of the same magnitude, we find a negative behavioral effect associated with regulation. Compensating this bias would require increasing the Pigovian price signal by up to 48.06/tCO2. Finally, based on a cross-product comparison, we show that the magnitude of behavioral effects declines with substitutability between clean and dirty product alternatives, a measure of effort to reduce emissions.

Energy efficiency, information, and the acceptability of rent increases: A multiple price list experiment with tenants
2018, Lang, Ghislaine, Lanz, Bruno
This paper studies the role of imperfect information and attentional biases in the context of energy efficiency investments in rented properties and associated split incentives. We design a multiple price list experiment representing owners’ decision to replace the central heating appliance, and employ both within-subject information disclosure and between-subject variation in information provision to quantify how tenants trade-off energy efficiency and rent increases. A set of quantile regressions suggests that information on expected energy bills reduction induces around 30% of tenants to equate financial savings and acceptable rent increase. Around 20% of tenants oppose rent increase and do not respond to information, whereas tenants’ valuation in the upper tail of the distribution exceeds financial savings, presumably on account of pro-environmental motives. By contrast, information on energy bills variability dampens acceptable rent increase. Our results highlight the importance of realistic ex-ante estimates of financial savings associated with energy efficiency investments.
