Rationing mechanisms are widely used to allocate scarce resources caused by policy intervention. The effect of rationing on equilibrium usually depends on the rationing mechanism. However, stylized facts in the Chinese passenger vehicle market suggest that the quota on license plates shifts vehicle demand to the high-price end, regardless of whether rationing occurs through an auction or a lottery. This study provides a unified theoretical explanation and an empirical analysis for this finding. When the quota allocation process incurs opportunity costs, only the consumers with a high willingness-to-pay participate in the process, which shifts sales distribution to the high-price end.
