This thesis consists of four papers. The first two papers deal with the valuation of an endangered species, the African elephant. The third paper is on the assessment of attribute values for work trips. The fourth paper models the number of alternative travel modes for work trips. <p> Paper [I]...</p>

In a travel mode choice context, we use survey data to construct and test the significance of five individual specific latent variables – environmental preferences, safety, comfort, convenience and flexibility - postulated to be important for modal choice. Whereas the construction of the...

We evaluate the allocation rationality and ex ante cost efficiency of a major Swedish investment subsidy program, the “Local Investment Program” (LIP). The LIP, effective between 1998-2002, had dual purposes: to step up the pace at which Sweden transforms into an ecologically sustainable...

Previous research on the willingness to pay (WTP) for risk reductions has almost systematically found the mean WTP for public risk reductions to be, both economically and statistically, significantly smaller than the mean WTP for private risk reductions. In this paper, we use socio-economic and...

We hypothesise that differences in people's attitudes and personality traits lead them to attribute varying importance to environmental considerations, safety, comfort, convenience and flexibility. Differences in personality traits can be revealed not only in the individuals' choice of...

This paper empirically evaluates a Swedish government subsidy to environmental sustainability, the Local Investment Programme (LIP). During the programme period, 1998 - 2002, more than 670 million was granted to 1814 different municipal projects, making it the largest Swedish subsidization to...

In 1998 the Swedish government launched its largest ecological subsidization programme to date, the Local Investment Programme (LIP). By having two political objectives; to step up the pace at which Sweden transforms into an ecologically sustainable society and to reduce unemployment, the...
