instrumented Explanation: We need the variables to be instrumented "The decision to favour methods using instrumentation over simple OLS should be seen as a trade-o between correlation and possible bias: in an OLS regression every variable acts as its own instrument, such that there is maximum correlation between the ***instrumented*** variable and the instrument (i.e. minimum standard errors). At the same time there is potentially maximum bias in the estimates | but whether the magnitude of this bias is economically signi cant or if there is any bias at all are issues we cannot know. Instrumental variable estimation might get be able to get rid of some of the bias, but the resulting loss in precision might outweigh this bene t". http://users.ox.ac.uk/~sjoh2052/ivtest.pdf |
