Abstract: |
Studies comparing household surveys with on-site interceptor surveys have
typically accounted for over-sampling avid users in the on-site interceptor
surveys (that is, endogenous stratification). However, these studies have
typically not accounted for the possibility that the household sample may
contain a large presence of zero observations. If a large proportion of the
population does not recreate at the site for any value of the price vector,
this inflation of zero observations leads to biased welfare estimates and an
inadequate comparison with the on-site survey. In this paper, the authors
estimate and compare three models which correct for these measurement issues
in both the household and on-site surveys. Results from an application to
recreation at Lake Sevan (Armenia) indicate that household consumers ' surplus
is not statistically different from that of the on-site survey once the
authors account for zero-inflation in the household sample and endogenous
stratification in the on-site sample. |
