Statistics, Econometrics & Mathematical Economics Question on The elasticity of demand and its measurement
The following table provides different statistical model specifications along with the elasticity of yt with respect to xt. Which one of the following options is correct ?Row | Statistical Model | Elasticity |
---|---|---|
1 | yt=β1+β2xt1ϵt | −xt2β2 |
2 | yt=β1−β2ln(xt)+ϵt | −xt2β2 |
3 | ln(yt) = β1 + β2 ln(xt) + εt | β2 |
4 | ln(yt) = β1 + β2xt + εt | β2xt |
5 | ln(yt) = β1 + β2 ln(xt) + εt | β2 exp(xt) |
6 | ln(yt) = β1 + β2xt + εt | β2exp(xt)1 |
