    Sammanfattning : It is contended in this thesis that the introduction of a legal regime with a rateless structure, subject only to market forces and a rebuttable statutory presumption as to where the rate line of conscience should be drawn, can provide a solution if the rate charged by pawnbrokers is to be regulated. The thesis also shows that a uniform pawn ticket issued as a negotiable document of title, and transferable by special indorsement, can provide a solution to problems caused by current activities related to pawn ticket transactions.
