Read the July $9,2006$ the Freakonomics column in the New York Times Magazine uploaded in this discussion board section of the module $.$ The authors examine a simple supply$-$and$-$demand gap with tragic implications: the shortage of human organs for transplantation. In the space of just a few decades, transplant surgery has become remarkably safe and reliable. But this success has bred huge demand: as more patients get new organs, more patients want them.

So$,$ while the number of kidney transplants has risen by $45\%$ in the past $10$ years, the number of people on a kidney waiting list has risen by $119\%.$ Consequently, some $3,500$ people die each year while waiting for a kidney transplant. A big problem is that would$-$be suppliers of kidneys, whether living or dead, are not given very strong incentives to step forward.

$1.$ Summarize the main arguments about providing incentives for the supply side of this volunteer market.

$2.$ Evaluate the argument carefully. What do you think? Why?
