How to interpret a regression coefficient of an independent variable expressed as a percentage? I fitted a continuous dependent variable against two explanatory variables. However, one of the explanatory variables is expressed as a percentage. Consider the regression model: $y = 0.05 + 0.032x_1 + 0.024x_2,$ where $x_2$ is expressed as a percentage. How can one interpret $\hat{\beta}_2=0.024$?

The interpretation is not very different from the normal regression interpretation: a 1 unit (in this case 1% EDIT: 1 percentage point, to be precise) increase in $x_2$ is associated with a 0.024 unit increase in $y$.
