There is strong resistance against the commercialization of some goods and services. If a person holding public authority sells her decisions, this is regarded as corruption. Most countries are also opposed against selling organs, university admission, or opportunities to clerk with prestigious courts. Yet decisions have to be made, and frequently demand exceeds supply. How can these decisions be made convincingly? Over the last decades, attempts at allocating goods or services without the help of money have become an active area of research in economics, under the label of matching. The legal community has taken fairly little notice of this development. This interface is the topic of the symposium.
