ALinearProgrammingApproachtoAuctionsandMatching
The digital economy has led to many new services where supply is matched with
demand for various types of goods and services. More and more people and organi-
zations are now in a position to design market rules that are being implemented in
software.
The design of markets is challenging as it is necessary to consider the strategic
behaviorofmarketparticipants,psychologicalfactors,andcomputationalproblemsin
ordertoimplementtheobjectivesofadesigner.Marketmodelsineconomicshavenot
lost their importance, but recent years have led to many new insights and principles
for the design of markets which are beyond traditional economic theory. This book
introducesthefundamentalsofmarketdesign,anengineeringfieldconcernedwiththe
designofreal-worldmarkets.
