ABSTRACT
A mixed bureau—one that receives part of its financing from a grant and part from the sale of a service—faces two separate demands for the same service. An increase in the output of a service inherently increases the output available to both groups by the same amount, so any service supplied by a mixed bureau has the critical characteristic of a "public" service. Usually, a mixed bureau have a significantly different type of relation with its sponsor than with its customers. An increase in customer demand for the A mixed bureau supplying a single service under conditions which permit price discrimination has an output and budget identical to that of a monopoly bureau which has two sponsors. The process of estimating and appropriating the total value that a sponsor and the customers are willing to pay for a service are different, but the results are the same.
