dc.description.abstract | Recent years of the 21st century have seen the emergence of space tourism activities. This
study analyzes data from a discrete choice experiment (DCE) on preferences for traveling
into space conducted in Norway. In the DCE, we asked a representative sample of
Norwegian individuals to express their optimal decision if faced with three alternatives:
two different space travel options and a no-purchase/no travel option. After getting answers
from the six choice cards from each respondent, we formulate utility functions that form
the basis for estimating preferences and willingness to pay for space travel and space trip
attributes. Multinomial logit estimation techniques are utilized to econometrically analyze
the stated preference survey data. We found that mortality risk, trip cost, and carbon
footprint negatively affect respondents’ preferences. In contrast, longer space trips in terms
of time and distance in space bring more satisfaction and higher purchasing probabilities.
Furthermore, prior interest and knowledge, sensation-seeking tendencies, age, gender, and
social connection are significantly correlated with preferences for space travel, while
income, education, family connections, and climate change concern appear to have no
statistical influence on the stated choices of the respondents. Descriptive statistics from a
likelihood question posed twice in the survey (before and after the DCE) indicate that about
48% of the respondents would go to space if one were offered the trip for free or if money
was no issue. Econometric analysis of the DCE data yields a similar finding, though there
is a difference across the two DCE versions, the CO2 emission version and the non-CO2
emission version. Specifically, the market shares are smaller at any trip price when we
include the individual’s carbon footprint. The estimation results indicate that 1/5 of
ordinary Norwegians would be willing to pay between NOK 2.42 million and NOK 4.27
million (financed with a loan paid back over ten years at zero interest rate) for a space trip.
The corresponding overall reservation price, i.e., the maximum willingness to pay, ranges
from NOK 15.77 million to NOK 16.5 million. | |
