TL;DR: In this article, the use of instruments that explain little of the variation in the endogenous explanatory variables can lead to large inconsistencies in the IV estimates even if only a weak relationship exists between the instruments and the error in the structural equation.

TL;DR: This paper found that completing a bachelors degree was worth more than the human capital acquired during three years of college, and the marginal returns to receiving either an academic or an occupational associates degree were statistically significant for White women raising wages by 10-20%.

TL;DR: This paper found that individuals who are more willing to take risks are more likely to migrate between labor markets in Germany, and this result is robust to stratifying by age, sex, education, national origin and a variety of other demographic characteristics, as well as to the level of aggregation used to define geographic mobility.

TL;DR: This article examined the effects of the old and new questions on the estimated return(s) to education and found that both the estimated linear return and the estimated college-high-school wage differential are slightly larger using information from the new question.

TL;DR: In this paper, the authors present evidence that estimates based on this "shift-share" instrument conflate the short-and long-run responses to immigration shocks, and propose a "multiple instrumentation" procedure that isolates the spatial variation arising from changes in the country-of-origin composition at the national level and permits them to estimate separately the short and long run effects.
