But did you know all of the content you post on many of these sites immediately become partially owned by the sites themselves? And, taking items away by deleting them never really gets rid of them. In fact, in Groundswell by Bernoff and Li, they state that trying to take something off the Internet that you have posted is like trying to remove pee from a pool. Scott McNealy, founder of Sun Microsystems, perhaps sums it up best, “You have zero privacy anyway. Get over it.†Keep in mind that technology is everywhere all the time (ubiquitous) because of the onset of smartphones, and other mobile devices. You have a 21st century phenomenon.

- What economic process causes a portion of a network good's demand curve to slope downward? lower production costs the income effect the substitution effect a saturated marketarrow_forwardWhat Is Cost-Based Pricing Models?arrow_forwardNathan and Joe are shopping for video games. The demand function of George for Track and field games is Q = 40 - 4P, and Georgia’s demand function is Q = 36 - 3P. What will their combined demand be if the price is $2? $10? If we add George and Georgia’s demand functions, we get: At $2 a game, both George and Georgia’s will have positive demand for field games, and so we can use the combined equation to getAt $10 a game, however, George’s demand function gives negative demand, which we know means he just has 0 demand for field games. In this case, we ignore George's function, and just use Georgia’s to figure out their combined demand, since using the combined function would give the wrong answer.arrow_forward
