Data Envelopment Analysis (DEA) is proposed as a method for measuring the e
fficiency of presidential campaigns. Campaign efficiency is defined as the
success of incumbent party candidates in converting the economic conditions
and presidential popularity of July into actual votes in November. DEA is
described and illustrated using a case study (US presidential elections 194
8-1996). Differences between outcome and efficiency and reasons for ineffic
iencies are explored. (C) 1999 Elsevier Science Ltd. All rights reserved.
