Instrumental Variables Regression with Weak Instruments
This paper develops asymptotic distribution theory for instrumental variable regression when the partial correlation between the instruments and a single included endogenous variable is weak, hereExpand
Estimating Teacher Impacts on Student Achievement: An Experimental Evaluation
We used a random-assignment experiment in Los Angeles Unified School District to evaluate various non-experimental methods for estimating teacher effects on student test scores. Having estimatedExpand
Instrumental Variables Regression with Weak Instruments
This paper develops asymptotic distribution theory for instrumental variable regression when the partial correlation between the instruments and a single included endogenous variable is weak, hereExpand
The Promise and Pitfalls of Using Imprecise School Accountability Measures
In recent years, most states have constructed elaborate accountability systems using school-level test scores. However, because the median elementary school contains only 69 children per grade level,Expand
Have We Identified Effective Teachers? Validating Measures of Effective Teaching Using Random Assignment. Research Paper. MET Project.
TLDR
This study tested whether a measure created by study authors could identify teachers who are effective at increasing student achievement and how well the teacher effectiveness measure identified teachers who were improving student performance beyond their expected gains. Expand
How Precise are Estimates of the Natural Rate of Unemployment?
This paper investigates the precision of conventional and unconventional estimates of the natural rate of unemployment (the 'NAIRU'). The main finding is that the NAIRU is imprecisely estimated: aExpand
The NAIRU, Unemployment and Monetary Policy
This paper examines the precision of conventional estimates of the NAIRU and the role of the NAIRU and unemployment in forecasting inflation. The authors find that, although there is a clearExpand
The recent surge in nurse employment: causes and implications.
TLDR
Registered nurse (RN) employment has increased during the current recession, and the recent increase in employment is improving projections of the future supply of RNs, yet large shortages are still expected in the next decade. Expand
Estimating Returns to Schooling When Schooling is Misreported
We propose a general method of moments technique to identify measurement error in self-reported and transcript-reported schooling using differences in wages, test scores, and other covariates toExpand
Parental Preferences and School Competition: Evidence from a Public School Choice Program
This paper uses data from the implementation of a district-wide public school choice plan in Mecklenburg County, North Carolina to estimate preferences for school characteristics and examine theirExpand
