You can obtain the same results if you make the following changes to the last two options in your xtabond2 command line:
Code:
iv(i.time lnwi, eq(lev)) gmm(wlnyw n g_ef nda, lag(1 1) eq(lev) passt)
As another comment: Specifying lags of wlnyw n g_ef nda as instruments for the level model without a first-difference transformation of the instruments requires that those instruments are uncorrelated with the unit-specific "fixed effects". This assumption is violated by construction for lags of the dependent variable.
