As well as nding and gaining loyalty from customers, we have seen
how big data can be used to increase margins through price discrimina-
tion. Regardless of the ethical questions surrounding the charging of dif-
ferent prices to dierent customers for the same products, the temptation
to secure a higher margin from those willing to pay more will not disap-
pear and will likely become more common as big data spreads. Along with
purchased data, geography, and web-browsing history, we can expect data
about customers to come from general data, such as weather or economic
trends in the areas where the customers live, as well as specic informa-
tion such as the example of solar panels gleaned from Google Earth images
