Divide betas in Stata

Dear Statalists,

I would like to estimate two regressions and divide the estimated betas (i.e. compute the point estimate, s.e., p-value, etc., just like the lincom command does). The first regression is a reduced form model:

Code:

reg y v dv, robust

The second regression is the first stage:

Code:

reg era v dv, robust

I want to get an IV- estimate (dv is the excluded instrument) and I need a Stata command to divide _b[dv] from the reduced form regression by _b[dv] from the first stage regression. Is there a way to do this in Stata? Thanks.
