Need help with this question. consider the regression:

log(D)=b+log(p)+u Describe a scenario that could result in a positive oLS estimate of , when the true underlying price elasticity is negative. (It may be useful to think about a standard supply/demand diagram here) log(D)=b+log(p)+u Describe a scenario that could result in a positive oLS estimate of , when the true underlying price elasticity is negative.
