Question

If a coefficient is greater in the tsls iv model than the ols model, with similar standard errors, what conclusions can be made

Answer 1

OLS model is progeny = B0 + B1 education + B2 age + B3 age^2 + u

TSLS IV model has firsthalf as an IV for education

OLS B1 = -0.2

TSLS IV B1 = -0.1
