Abstract [en]

Visitors to big tourist cities are very likely heterogeneous and can be classified into different segments, for example, low and high spenders. Previous studies on visitor expenditure-based segmentation seem to have only taken into account observed heterogeneity, usually segmenting tourists based on observed characteristics. In the present study, however, the visitors to Venice, Italy, are segmented with respect to their spending into different groups based on both observed and unobserved heterogeneity using a finite mixture model. The results indicate that the visitors belong to three latent classes with respect to their expenditure. Interestingly, different variables affect expenditure differently depending on the latent class belonging. The overall conclusion is that segmenting tourists into different classes based on unobserved heterogeneity with respect to their spending is preferable and more informative than treating the visitors as one homogeneous group. The approach is also more useful for different types of policymaking.

Abstract [en]

This paper presents a relatively simple procedure to examine the responsiveness of energy demand to measures of economic activity and electricity price. We estimate the demand function for electricity both for households and for industry in 29 countries, mainly European countries, in the last 10 years, using a panel aggregate data.

Preliminary results suggest, as expected, that price has a negative significant effect on the electricity consumption. This is the case for both households and industry level for the same sample of countries. Our results also suggest that short-run elasticity of electricity consumption with respect to aggregate output seems to have been stable and unit elastic during the last decade. Moreover, price elasticity is more elastic and more stable in the industry sector than households are.

Abstract [en]

This study concerns factors influencing international tourists’ length of overnight stay in Venice. The data are from a survey conducted by the Bank of Italy on international tourism. Both zero-truncated negative binomial (ZTNB) and ordinary least squares (OLS) regressions are estimated. In general, the estimates from ZTNB and OLS regressions are similar. The results suggest that age, returning directly to the country of residence and the summer season have a positive influence on the length of stay. On the other hand, international tourist expenditure and visiting other places than Venice have a negative impact on the length of stay. Moreover, the average length of overnight stays differs among nationalities and those who have visited Venice previously tend, on average, to stay longer. One finding is that visitors from North America and Australia stay longer and spend more than visitors coming from neighbouring countries.

Abstract [en]

Understanding the demand and the economic impact for a hallmark event is crucial knowledge not only for the event managers but also for the public planners of the host region, especially from the viewpoint of welfare evaluation. The purpose of this paper is twofold. Firstly to estimate the demand for a music event using two non-market valuation techniques; stated choice and travel cost method (TCM), and secondly to compare the welfare measures estimated from the two methods and discuss their relevance for event policy and management. We use survey data collected from 1005 visitors to the Peace & Love music festival held in Borlänge, Sweden, in 2012. The survey contains questions about the actual behaviour of the respondents such as expenditure patterns and travel behaviour but also a stated choice experiment (SCE). The latter asks the respondents to choose between different scenarios with varying levels of price, number of visitors and length of the festival in days. These data allow us to estimate consumer surplus for the event by applying both the TCM and SCE. The findings of our study are that the price effect, as expected, is negative and significant, more people attending the festival decreases the propensity to attend while longer duration of the festival increases the propensity to attend. This paper contributes to the literature on event impact analysis by highlighting the potential for using stated choice data on visitor preferences in combination with actual visitor data to understand current and future economic impact of an event.

Abstract [en]

In this paper we investigate how attitudes to health and exercise in connection with cycling influence the estimation of values of travel time savings in different kinds of bicycle environments (mixed traffic, bicycle lane in the road way, bicycle path next to the road, and bicycle path not in connection with the road). The results, based on two Swedish stated choice studies, suggest that the values of travel time savings are lower when cycling in better conditions. Surprisingly, the respondents do not consider cycling on a path next to the road worse than cycling on a path not in connection to the road, indicating that they do not take traffic noise and air pollution into account in their decision to cycle. No difference can be found between cycling on a road way (mixed traffic) and cycling in a bicycle lane in the road way. The results also indicate that respondents that include health aspects in their choice to cycle have lower value of travel time savings for cycling than respondents that state that health aspects are of less importance, at least when cycling on a bicycle path. The appraisals of travel time savings regarding cycling also differ a lot depending on the respondents’ alternative travel mode. The individuals who stated that they will take the car if they do not cycle have a much higher valuation of travel time savings than the persons stating public transport as the main alternative to cycling.

Abstract [en]

Forestry residues as a renewable energy source are becoming increasingly competitive to fossil fuels. An important issue, however, is effective transportation solutions for this type of material. In this paper we describe and discuss several alternative vehicle systems which have been used in Sweden. We describe and discuss a specialized vehicle for the transportation of loose residues, bundled residues, and tree sections; a specialized stump hauling vehicle; a recently developed vehicle for the transportation of bundled residues; a container system vehicle for stump transportation. All these different machineries have their merits and shortcomings depending on the type of forest energy product.
