OLS estimation; small standard error

[benniba]

Hi, I have a question regarding small standard errors regarding question 11.7 in Wooldridge about the wages and productivity. The coefficient for productivity(outputhr)=1.64, hence a one percentage increase in productivity increases real wage by 1.64%, and the standard error is (0.09). In the interpretation it says that "The estimated elasticity seems too large, because the standard error is so small, the 95% confidence interval excludes a unit elasticity" what does this mean?
Thanks a lot for replies in advance
