The Iranian model of kidney transplantation is an example of a regulated living unrelated renal donation. In this paper, we collected and analyzed a unique dataset of 436 paired kidney donors and recipients, including their characteristics and the realized price of a kidney in Mashhad. As opposed to the global picture of kidney donation, we find that women are less likely to donate and more likely to receive a kidney. Moreover, the average price of a kidney amounts less than 2 years of work with the minimum level of wage.
