Individual Carbon Footprint Reduction: Evidence from Pro-environmental Users of a Carbon Calculator
- 2023
-
In: Environmental & Resource Economics. - : Springer. - 0924-6460 .- 1573-1502. ; 86, s. 433-467
-
Journal article (peer-reviewed)abstract
- We provide the first estimates of how pro-environmental consumers reduce their total carbon footprint using a carbon calculator that covers all financial transactions. We use data from Swedish users of a carbon calculator that includes weekly estimates of users' consumption-based carbon-equivalent emissions based on detailed financial statements, official registers, and self-reported lifestyle factors. The calculator is designed to induce behavioral change and gives users detailed information about their footprint. By using a robust difference-in-differences analysis with staggered adoption of the calculator, we estimate that users decrease their carbon footprint by around 10% in the first few weeks, but over the next few weeks, the reduction fades. Further analysis suggests that the carbon footprint reduction is driven by a combination of a shift from high- to low-emitting consumption categories and a temporary decrease in overall spending, and not by changes in any specific consumption category.

Direct and spillover effects of a social information campaign on residential water-savings
- 2018
-
In: Journal of Environmental Economics and Management. - : Elsevier BV. - 0095-0696. ; 92, s. 222-243
-
Journal article (peer-reviewed)abstract
- This paper investigates direct and spillover effects of a social information campaign aimed at encouraging residential water savings in Colombia. The campaign was organized as a randomized field experiment, consisting of monthly delivery of consumption reports, including normative messages, for one year. Results indicate that social information and appeals to norm-based behavior reduce water use by up to 6.8% in households directly targeted by the campaign. In addition, we find evidence of spillover effects: households that were not targeted by the campaign reduced water use by 5.8% in the first six months following the intervention. © 2018 Elsevier Inc.

The Use of Green Nudges as an Environmental Policy Instrument
- 2021
-
In: Review of Environmental Economics and Policy. - : University of Chicago Press. - 1750-6816 .- 1750-6824. ; 15:2, s. 216-237
-
Journal article (peer-reviewed)abstract
- This article discusses the use of green nudges—behavioral interventions aimed at reducing negative externalities—as an environmental policy instrument. We present a new framework for classifying nudges according to how they affect behavior. Pure nudges change the choice environment to guide behavior unobtrusively. Moral nudges trigger a psychological reaction to encourage behavior change. Our review of empirical studies reveals that green nudges, pure or moral, can have a significant impact on behavior and the environment but that the effects are highly context dependent. On the basis of both our review and basic welfare economics models, we discuss key factors for policy makers to consider when choosing between implementing a green nudge and implementing conventional policy instruments.

Distributional preferences in adolescent peer networks
- 2023
-
In: Experimental Economics. - : Springer Science and Business Media LLC. - 1386-4157 .- 1573-6938. ; 26, s. 223-248
-
Journal article (peer-reviewed)abstract
- We study distributional preferences in adolescent peer networks. Using incentivized choices between allocations for themselves and a passive agent, children are classified into efficiency-loving, inequality-loving, inequality-averse, and spiteful types. We find that pairs of students who report a friendship link are more likely to exhibit the same preference type than other students who attend the same school. The relation between types is almost completely driven by inequality-loving and spiteful types. The role of peer networks in explaining distributional preferences goes beyond network composition effects. A low rank in academic performance and a central position within the network relate positively to a higher likelihood of being classified as spiteful. Hence, social hierarchies seem to be correlated with distributional preference types.

The marginal values of noise disturbance from air traffic : does the time of the day matter?
- 2004
-
In: Transportation Research Part D. - Oxford : Pergamon Press. - 1361-9209 .- 1879-2340. ; 9:5, s. 373-385
-
Journal article (peer-reviewed)abstract
- This paper analyzes the marginal willingness to pay for changes in noise levels related to changes in the volume of flight movements at a city airport in Stockholm, Sweden, by using a choice experiment. When estimating marginal willingness to pay for different times of the day and days of the week, we find that these vary with the temporal dimensions: mornings and evenings have higher marginal values. Interestingly, a substantial proportion of the respondents prefer no changes in the current noise level. The paper concludes with a policy discussion related to incentive-based pricing.

Funding a New Bridge in Rural Vietnam: A field experiment on conditional cooperation and default contributions
- 2011
-
Reports (other academic/artistic)abstract
- The ability to provide public goods is essential for economic and social development, yet there is very limited empirical evidence regarding contributions to a real local public good in developing countries. This paper analyzes a field experiment where 200 households in rural Vietnam could make real contributions to an archetypical public good, a bridge. In particular, we study the role of two kinds of social influence: i) conditional cooperation, i.e., that people may be more willing to cooperate if others do, and ii) the effects of the default alternative, i.e., that people are influenced by the default alternative presented to them in the choice situation. We find significant and substantial effects of both kinds of influence. For example, by either giving the subjects the additional information that one of the most common contributions by others is 100,000 dong (a relatively low contribution) or introducing a zero-contribution default alternative, the average contribution decreases by about 20% compared to the baseline case.

Individual Carbon Footprint Reduction: Evidence from Pro-environmental Users of a Carbon Calculator
- 2022
-
Other publication (other academic/artistic)abstract
- We provide the first estimates of how pro-environmental consumers reduce their total carbon footprint using a carbon calculator that covers all financial transactions. We use data from users of a carbon calculator that includes weekly estimates of users’ consumptionbased carbon-equivalent emissions based on detailed financial statements, official registers, and self-reported life-style factors. The calculator is designed to induce behavioral change and gives users detailed information about their footprint, and includes social comparisons, and goal-setting options. By using a robust difference-in-differences analysis with staggered adoption of the calculator, we estimate that users decrease their carbon footprint by around 10 percent in the first few weeks, but over the next few weeks, the reduction fades. Further analysis suggests that the carbon footprint reduction is driven by a combination of a shift from high- to low-emitting consumption categories and a temporary decrease in overall spending, and not by changes in any specific consumption category.

A framework for selecting and designing policies to reduce marine plastic pollution in developing countries
- 2020
-
In: Environmental Science and Policy. - : Elsevier BV. - 1462-9011 .- 1873-6416. ; 109:July 2020, s. 25-35
-
Journal article (peer-reviewed)abstract
- © 2020 The Authors The polluting of marine ecosystems with plastics is both a global and a local problem with potentially severe consequences for wildlife, economic activity, and human health. It is a problem that originates in countries’ inability to adequately manage the growing flow of waste. We use an impact pathway framework to trace the flow of plastics through the socio-ecological system and identify the role of specific policy instruments in achieving behavioral changes to reduce marine plastic waste. We produce a toolbox for finding a policy that is suitable for different countries. We use the impact pathway and toolbox to make country-specific recommendations that reflect the reality in each of the selected countries.

The impact of stay-at-home policies on individual welfare
- 2022
-
In: Scandinavian Journal of Economics. - : Wiley. - 0347-0520 .- 1467-9442. ; 124:2, s. 340-362
-
Journal article (peer-reviewed)abstract
- In this paper, we perform a choice experiment assessing the impact of stay-at-home policies on individual welfare. We estimate the willingness to accept compensation (WTA) for restricting non-working hours in Sweden during the COVID-19 pandemic. The WTA for a one-month stay-at-home policy is about US$480 per person, or 9.1 percent of Sweden's monthly per capita GDP. Stricter lockdowns require disproportionately higher compensation than more lenient ones, indicating that strict policies are cost-effective only if they are much more successful in slowing the spread of the disease. Moreover, older people have a higher WTA of staying home than the rest of the population.
