Conformity and the demand for environmental goods
- 2008
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- We test the hypothesis that people conform to certain social norms, i.e. that some individuals may be willing to pay a higher price premium for green products the more widespread green consumerism is in society. To investigate consumer preferences for environmentally friendly products, we conducted a choice experiment where the respondents were asked to choose among coffee products varying with respect to their share of ecological beans, share of fair trade beans, and price. Three treatments were used, differing only in the information given about the choices made by other consumers. More specifically, the respondents in the three subgroups were told that 10%, 50%, and 90% of all other consumers chose the alternative with 100% ecological beans. We find different responses to the treatments across individuals. In particular, we can only confirm our hypothesis of conformity for women, although men appear to have stronger preferences for ecological coffee than women.

Evaluating the welfare effects of improved water qualityusing the choice experiment method
- 2004
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This paper analyzes the welfare effects of improved health status through increased water quality using a choice experiment. The survey was administered to a random sample of households in metropolitan Cairo, Egypt. We apply a random parameter logit model in the analysis and illustrate the richness of information that can be obtained from this type of model by estimating individual level willingness to pay (WTP). We find a significant WTP for improved health status, both for short-run and long-run health effects. However, the estimated WTP is fairly low compared with the costs of a program that would achieve these improvements.

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.

A fair share: Burden-sharing preferences in the United States and China
- 2013

Ingår i: Resource and Energy Economics. - 0928-7655. ; 35:1, s. 1-17
-
Tidskriftsartikel (refereegranskat)abstract
- Using a sequential discrete choice experiment, we investigate preferences for distributing the economic burden of reducing 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 relative (1) historical emissions, (2) income level, (3) emissions per capita, and (4) current emissions. We found that respondents overall favored the rule that was least costly for their country. In addition, the willingness to pay was much higher in China, suggesting that how mitigation costs are shared across countries is more important for Chinese than for Americans. To some extent the willingness to pay varies with socioeconomic characteristics and attitudes. For example, university-educated respondents in the United States are willing to pay more for the rule that is the least costly for their own country, compared with those with a lower education level. At the same time, the ranking of the two most preferred rules are generally robust across all socioeconomic groups within each country.

Airline choice, switching costs and frequent flyerprograms
- 2004
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Switching costs are costs that customers face when switching from one firm to another. In markets such as the airline market where repeated purchases are common, switching costs may be substantial. In this paper we estimate the switching costs for domestic airline routes in Sweden between 1992 and 2002. In addition we also test for the determinants of switching costs. In particular we test to what extent factors such as frequent flyer programs and flag carriers have an effect on switching costs. The paper ends with a brief discussion on the welfare consequences of switching cots, where the connection between habit formation and switching costs is discussed.

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.

Tidskriftsartikel (refereegranskat)abstract
- Using papers submitted to an international conference on economics held in Sweden in 2008, we analyze how gender, as well as other characteristics of the authors and reviewers, affects the grading of these papers by the reviewers. Correcting for other variables, including the country and research field, as well as the academic level of the author, we focus on the difference in grades between blind and non-blind review treatments. We find that non-blind reviewing has little effect, and there is no significant evidence of gender discrimination. Furthermore, we do not find any significant difference between the average grading by female and male reviewers.

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.
