a) Assuming that CDSS’s reduce medical practice variation by minimizing medical errors, it can be hypothesized that widespread employment of expert systems will decrease welfare loss and alleviate its accumulation in society as a function of a more standardized approach in health care delivery (again, as a result of reduced numerator in cov² / n). This statement is valid both for short-term and long-term effects.

a) WL will diminish also due to decrease in expenditures (as been demonstrated in the section above), in its turn resulting from:

- Decrease in Quantity of services only in the short-run
or :
- Decrease in both Price and Quantity in the long-term

The amount of WL would purely depend on the interplay of estimates of P and Q when considering short-term effects, which is difficult to anticipate at this point.
