| Abstract: | The value of an accurate accounting system is compared to one that introduces a cross-subsidy. In a two-product experimental market the accurate system is shown to provide value when a competitor has a system that introduces a cross-subsidy. The value appears to arise from better product-mix decisions. But it is likely that this value is transitory, explaining in part why observational studies of practice have found it difficult to document sustained value from improved information systems. |
