Synergies and Trade-offs between Climate and Local Air Pollution: Policies in Sweden
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In this paper, we explore the synergies and tradeoffs between abatement of global and local pollution. We built a unique dataset of Swedish heat and power plants with detailed boiler-level data 2001-2009 on not only production and inputs but also emissions of CO2 and NOx. Both pollutants are subject to strict policies in Sweden. CO2 is subject to multiple levels of governance using environmental instruments such as the EU ETS and Swedish carbon taxes; NOx – as a precursor of acid rain and eutrophication – is regulated by a heavy fee. Using a quadratic directional output distance function, we characterize changes in technical efficiency as well as patterns of substitutability in response to the policies mentioned. The fact that generating units face a trade-off between the pollutants indicates a need for policy coordination.

Diffusion of NOx abatement technologies in Sweden
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This paper studies how different NOx abatement technologies have diffused under the Swedish system of refunded emissions charges and analyzes the determinants of the time to adoption. The policy, under which the charge revenues are refunded back to the regulated firms in proportion to energy output, was explicitly designed to affect investment in NOx-reducing technologies. The results indicate that a higher net NOx charge liability, i.e. a reduction in tax liabilities net of the refund due to the new technology, increases the likelihood of adoption, but only for end-of-pipe post-combustion technologies. We also find some indication that market power considerations in the heat and power industry reduce the incentives to abate emissions through investment in postcombustion technologies. Adoption of post-combustion technologies and the efficiency improving technology of flue gas condensation are also more likely in the heat and power and waste incineration sectors, which is possibly explained by a large degree of public ownership in these sectors.

A Fair Share : Burden-Sharing Preferences in the United States and China
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Using a choice experiment, we investigated preferences for distributing the economic burden of decreasing CO2 emissions in the two largest CO2-emitting countries: the United States and China. We asked respondents about their preferences for four burden-sharing rules to reduce CO2 emissions according to their country’s 1) historical emissions, 2) income level, 3) equal right to emit per person, and 4) current emissions. We found that U.S. respondents preferred the rule based on current emissions, while the equal right to emit rule was clearly least preferred. The Chinese respondents, on the other hand, preferred the historical rule, while the current emissions rule was the least preferred. Respondents overall favored the rule that was least costly for their country. These marked differences may explain the difficulties countries face in agreeing how to share costs, presenting a tough hurdle to overcome in future negotiations. We also found that the strength of the preferences was much stronger in China, suggesting that how mitigation costs are shared across countries is more important there.

Discrimination in Scientific Review - A natural field experiment on blind versus non-blind review
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This paper analyzes the impacts of gender, as well as other author characteristics, on reviewers’ grading of papers submitted to an international conference in economics in Sweden in 2008. Correcting for other variables, including country and research field as well as researcher academic level, we focus on the difference in grades between blind and non-blind review treatments. We find little effect of non-blind reviewing and no significant evidence of gender or any other type of discrimination. Furthermore, we do not find any significant difference between the average grading by female and male reviewers.

Food labels: how consumers value moral, environmental, and health aspects of meat consumption
- 2020
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Policy changes could improve health and environmental outcomes by addressing the many externalities and internalities related to food consumption. Using a stated preference approach, we investigate to what extent consumers are willing to make costlier food consumption choices if doing so contributes to decrease environmental externalities, health damages, and animal suffering. We find a considerable willingness to pay for some aspects of the food bought. People are willing to pay an additional 50% for a product if it carries a label declaring that the product meets the highest available standards in terms of healthiness, animal welfare, and antibiotics use, respectively. The willingness to pay for a climate impact label is also sizeable but smaller. We compare a traffic-light label with a plain-text label and a grey-scale label in order to disentangle the effects of introducing labels Our results are mixed, suggesting that a traffic-light label has both normative and cognitive effects on behavior.

Is Fairness Blind? - The effect of framing on preferences for effort-sharing rules
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- By using a choice experiment, this paper focuses on citizens’ preferences for effort-sharing rules of how carbon abatement should be shared among countries. We find that Swedes do not rank the rule favoring their own country highest. Instead, they prefer the rule where all countries are allowed to emit an equal amount per person, a rule that favors Africa at the expense of high emitters such as the U.S. The least preferred rule is reduction proportional to historical emissions. Using two different treatments, one where the respondents were informed about the country names and one where the country names were replaced with anonymous labels A-D, we also test whether people’s preferences for effort-sharing rules depend on the framing of the problem. We find that while the ranking of the principles is the same in both treatments, the strength of the preferences is significantly increased when the actual names of the countries are used.

Leading by example? EU citizens’ preferences for climate leadership
- 2022
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- For global problems like climate change, strong international agreements are difficult to achieve. Alternative solutions might therefore be necessary. In this paper, we study the support for climate leadership in seven European countries. Climate leadership means that an individual country takes the lead by decreasing its carbon emissions above its level of commitment in the current EU agreement and with the intention of inspiring other countries to do likewise. Overall, we find that at realistic cost levels, a majority of people oppose their country taking the lead, and most do not expect that taking the lead will result in other countries following suit. The lack of support is caused by expectations that such leadership will result in other countries behaving as free riders. We do, however, find evidence of preferences for conditional leadership: People are more positive about their country taking the lead if assured that other countries will follow. These preferences are stronger among those who identify as leftwing. Moreover, citizens in smaller countries are more pessimistic that other countries would follow their country’s lead and more sensitive to the response of other EU countries.

Paying for Mitigation: A Multiple Country Study
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Unique survey data from a contingent valuation study conducted in three different countries (China, Sweden, and the United States) were used to investigate the ordinary citizen’s willingness to pay (WTP) for reducing CO2 emissions. We find that a large majority of the respondents in all three countries believe that the mean global temperature has increased over the last 100 years and that humans are responsible for the increase. A smaller share of Americans, however, believes these statements, when compared to the Chinese and Swedes. A larger share of Americans is also pessimistic and believes that nothing can be done to stop climate change. We also find that Sweden has the highest WTP for reductions of CO2, while China has the lowest. Thus, even though the Swedes and Chinese are similar to each other in their attitudes toward climate change, they differ considerably in their WTP. When WTP is measured as a share of household income, the willingness to pay is the same for Americans and Chinese, while again higher for the Swedes.

The Climate Decade: Changing Attitudes on Three Continents
- 2020
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- We examine how attitudes and willingness to pay (WTP) for climate policies have changed over the past decade in the United States, China, and Sweden. All three countries exhibit an increased willingness to pay for climate mitigation. Ten years ago, Sweden had a larger fraction of believers in anthropogenic climate change and a higher WTP for mitigation, but today the national averages are more similar. Although we find convergence in public support for climate policy across countries, there is considerable divergence in climate attitudes and preferences within countries, particularly the United States. Political polarization explains part of this divergence.

The Truth, the Whole Truth, and Nothing but the Truth - A Multiple Country Test of an Oath Script
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Hypothetical bias is one of the main issues bedeviling the field of nonmarket valuation. The general criticism is that survey responses reflect how people would like to behave, rather than how they actually behave. In our study of climate change and emissions reductions, we took advantage of the increasing bulk of evidence from psychology and economics that addresses the effects of making promises, in order to investigate the effect of an oath script in a contingent valuation survey. The survey was conducted in Sweden and China, and its results indicate that an oath script has significant effects on respondent behavior in answering willingness-to-pay (WTP) questions, some of which vary by country. In both countries, the share of zero WTP responses and extremely high WTP responses decreases when an oath script is used, which also results in lower variance. In China, the oath script also reduces the average WTP, cutting it by half in certain instances. We also found that the oath script has different impacts on various respondent groups. For example, without the oath script, Communist party members in China are more likely than others to have a positive WTP for emissions reductions, but with the oath script, there is no longer any difference between the groups.
