This paper reports the findings of a natural field experiment in which cross-country skiers had the option to use their mobile phones to call in a donation to fund ski track preparations. This paper takes the Right of Public Access as given and investigates the extent to which donations or voluntary contributions can be used to finance recreational infrastructure. The purpose of the study was to look at how different types of bonus services and offers, as well as the introduction of a trail pass, affected the willingness of individuals to make donations to ski track preparations at a Swedish ski resort. The study’s main finding was that it is not possible to rely on a simple voluntary approach when introducing a new system for financing recreational infrastructure using micropayments and new IT services.
