      abstract = {Despite continuing controversy, economic surplus has  continued to be
used in empirical cost-benefit analyses as  a measure of welfare to
producers and consumers. In this  paper, the issue of measuring
changes in producer and  consumer surplus resulting from exogenous
supply or demand  shifts in multi-market models is examined using a
two-input  and two-output equilibrium displacement model. When
markets  are related through both demand and supply,  significant
errors are possible when using conventional  economic surplus areas
incorrectly as is evident in some  applications in the literature.},
