1st Fold: DML elasticity: -1.90 OLS elasticity for comparison: -1.83 2nd Fold: DML elasticity: -1.92 OLS elasticity for comparison: -1.85 DML efficient estimate of elasticity: -1.91 So there we have it: our doubly robust, ML-controlled estimate of price elasticity of demand. That is, of the average
