This bring cross elasticity to a whole new level. Now that the elections in the US are done, it's sometimes hard to remember just how crazy campaigning can get. Candidates will grab at whatever statistics or new bits of knowledge that tell them how they're doing in the polls and or what they need to do to get ahead. This year, one of their focuses is...what kind of soda we drink? That's right, because cross elasticity is all about how two product correlate and the correlation between the president elect and your favorite soda has only like, what, 20, 30 degrees of separation? And you'd be surprised just how many other details of your life they'll look at to see where their target audience is.

This article talks about Lenovo's vision of growing demand for their 7-inch tablets. It suggests combinations of substitutes and complement goods, which has to do with the value of XED. They see tablets as competitors for large-screen smartphones (like Samsung S3), but also as something that will not replace traditional computers. So, value of XED in combination tablets - smartphones is positive, meaning that these two goods are substitutes, whereas the value of XED in combination tablets - computers is negative, meaning that these two goods are complements. Lenovo also suggests that they are prepared for the steady supply of high-resolution touch screens for which they see a bright future as components of computers. So, it is also about non-determinant of supply - expectation for future prices.
