An important question in auction theory is designing a dynamic efficient auction mechanism for multiple objects when bidders’ values are interdependent. Perry and Reny (REStud 2005) introduced an efficient auction for discrete homogeneous goods when bidders’ values are interdependent. In this paper, I propose an ascending auction mechanism for heterogeneous goods when bidders’ values are interdependent. I construct the auction mechanism by using a Perry and Reny auction mechanism for each type of good. I show that if agents' utility functions are additively separable in goods, quasilinear in money and agents’ budget constraints are not binding, then this auction mechanism has an efficient equilibrium outcome.
