 | | The economic surplus method is a refinement of benefit/cost analysis and, as the latter, measures the economic (efficiency) benefits associated with research alternatives. |
 | | Moreover, analysis in economic surplus terms can be used to show how economic policy interventions, such as commodity price ceilings, over-valued exchange rates, and/or subsidies and taxes, distort or even eliminate the welfare gains which might otherwise have been obtained from research. |
 | | The logic involved in the economic surplus benefit/cost model requires some knowledge of economic theory, and application is hampered by several difficulties including that of obtaining the necessary data on elasticities of supply and demand (see below for definition). |
