Q. Measurement problems in demands for resources?

Social influence- A student believes that smoking is really cool but since his friends think it's disgusting he doesn't smoke.

Measurement problems- Measuring attitudes is not easy. In several situations consumers don't consciously set out to enumerate how positively or negatively they feel about mopeds and when a market researcher asks them about their beliefs about mopeds how important these beliefs are and their evaluation of the performance of mopeds with respect to these beliefs consumers often don't give very reliable answers. Therefore the consumers may act constantly with their true attitudes which were never uncovered for the reason that an erroneous measurement was made.
