Jeg vet ikke hvordan, men…

… det ser ut til at noen har forsket på troverdigheten til vintersportsteder. Det ser ut til at jo bedre mobildekning, jo mindre vil stedet lyve om nysnøen.

Utgangspunktet er at økonomene mener alpinstedene lyver om hvor mye nysnø de har fått, for å trekke flere skiglade til stedet. Hvordan er man sikker på at 15 cm nysnø stemmer?

Det er økonomene ved Dartmouth College som har gått dette etter i sømmene.

Det er dekningskart fra AT&T med, det er data fra SNODAS, og det er 4 år med observasjoner.

Likning nr. 1 er denne:

srt =β*wt +aw +nr +ert (1)

Vestresiden er nysnø fra sted r, på tidpunkt t.

w er om det er en helg, a er en fixed effect for spesielle kalenderuker, n er en fixed effect for sted og e er restleddet.

Både Tobit og OLS benyttes, samt clustering av dag og resort for å kalkulerer standardavvikene.

In resort-reported snow (column 1), we find that the largest day of the week effects are for Saturday, Sunday, Friday, and Monday. Regardless of our definition of weekend, we find that resorts report 0.20-0.25 more inches of new natural snow on weekends.

In contrast, we do not find statistically significant evidence of a weekend effect in weather station or SNODAS data (columns 2-4). Point estimates of a weekend effect are positive for the sample of days for which we have a resort report, with magnitudes between 0.06 and 0.10 inches, or between 23 and 43 percent of the weekend effect in resort-reported snow.

In contrast to the weekend effects in resort reports, the weekend effects in government reports are far from statistically significant (p-values range from 0.22 to 0.53), and they are not present to any meaningful extent when we examine the full sample of resort*days from the 2004-2008 seasons. In our tests below, we will control for government-reported snow when testing for weekend effects.

Vi hopper til sammendraget, og innføringen av iPhone:

In all, the results suggest that deceptive advertising about product quality varies sharply with incentives, both within resorts (over time, at high-frequencies), and across resorts. They also suggest that consumers responded only weakly to exaggerated claims, and hence that advertisers reaped few benefits from deception in equilibrium. This may help explain why a
simple technology shock (the launch of the iPhone app) seems to have changed the equilibrium by dramatically reducing weekend exaggeration at resorts with better iPhone reception.

Har noen gjort noe liknende i Norge?
