One way to quantify how much these internet services are worth is by asking people how much they would give up to forgo using them for a year. A new working paper by Erik Byrnjolfsson, Felix Eggers and Avinash Gannamanen, three economists, does exactly this and finds that the value for consumers of some internet services can be substantial. Survey respondents said that they would have to be paid $3,600 to give up internet maps for a year, and $8,400 to give up e-mail. Search engines appear to be especially valuable: consumers surveyed said that they would have to be paid $17,500 to forgo their use for a year.
