An economist specifies a double-log (log-log) regression model: ln(Y)=β0+β1ln(X)+ϵ\ln(Y) = \beta_0 + \beta_1 \ln(X) + \epsilon, where YY is the quantity demanded of a product and XX is the price. If the estimated slope is β^1=1.5\hat{\beta}_1 = -1.5, what is the correct interpretation of this coefficient?
