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 |
