Does ignoring multidestination trips in the travel cost method cause a systematic bias? AgEcon
Kuosmanen, Timo; Nillesen, Eleonora; Wesseler, Justus.
The present paper demonstrates that treating multidestination trips (MDT) as single‐destination trips does not involve any systematic upward or downward bias in consumer surplus (CS) estimates because the direct negative effect of a price increase (treating MDT as a single‐destination trip) is offset by a shift in the estimated demand curve. Still, ignoring MDT can greatly underestimate or overestimate the CS. In addition, we demonstrate that there is a sound theoretical basis for using preference information for allocating travel costs between different sites included in the MDT package. A novel extreme value approach is proposed, which does not require any overly restrictive assumptions about consumer preferences. This approach is applied to the zonal...

Correcting for multiple destination trips in recreational use values using a mean-value approach; An application to Bellenden Ker National Park, Australia AgEcon
Nillesen, Eleonora; Wesseler, Justus; Cook, Averil.
This paper focuses on an empirical application of the travel cost method, to estimate the recreational use value of Bellenden Ker National Park, part of the Wet tropics World Heritage Area Queensland, Australia. Walking appears to be one of the main activities associated with recreational experiences in the region. Substantial socio-economic as well as environmental benefits are expected to be gained if the areas was to be developed further, with regard to walking tracks, provided that this would be done in an environmentally sustainable way. Two overnight tracks within the park have been selected to obtain information about visitors’ experiences with the tracks in the past, to address specific needs for possible future developments. A standard assumption...

Bt and Ht Corn versus Conventional Pesticide and Herbicide Use. Do Environmental Impacts Differ? AgEcon
Nillesen, Eleonora; Scatasta, Sara; Wesseler, Justus.
In this paper we empirically assess and compare the environmental impact of pesticide programs for Bt, Ht (glufosinate) and conventional corn in Europe, employing the Environmental Impact Quotient. We use field trial data from Narbons, France 2004 as well as secondary data. Our results show that management of Bt corn has a lower environmental impact than conventional corn programs. Herbicide treatment of the Ht variety also has a much lower environmental impact than that of the two conventional programs. Our empirical findings support the argument of lower environmental and health impacts with respect to pesticide use when growing Bt and Ht corn. The outcomes are relevant for environmental benefit-cost analysis of Bt and Ht corn.
