July 2020Teacher-to-Classroom Assignment and Student Achievement
with Bryan S. Graham, Geert Ridder, Petra M. Thiemann: w27543
We study the effects of counterfactual teacher-to-classroom assignments on average student achievement in elementary and middle schools in the US. We use the Measures of Effective Teaching (MET) experiment to semiparametrically identify the average reallocation effects (AREs) of such assignments. Our findings suggest that changes in within-district teacher assignments could have appreciable effects on student achievement. Unlike policies which require hiring additional teachers (e.g., class-size reduction measures), or those aimed at changing the stock of teachers (e.g., VAM-guided teacher tenure policies), alternative teacher-to-classroom assignments are resource neutral; they raise student achievement through a more efficient deployment of existing teachers.
June 2015Does Retirement Make You Happy? A Simultaneous Equations Approach
with Raquel Fonseca, Arie Kapteyn, Jinkook Lee
in Insights in the Economics of Aging, David A. Wise, editor
Continued improvements in life expectancy and fiscal insolvency of public pensions have led to increased pension entitlement ages in several countries, but its consequences for subjective well-being are largely unknown. Financial consequences of retirement complicate the estimation of effects of retirement on well-being as financial circumstances may influence well-being, so the effects of retirement may be confounded by income changes. Also, unobservable determinants of income are probably related with unobservable determinants of well-being, making income possibly endogenous if used as control in well-being regressions. To address these issues, we estimate a simultaneous model of retirement, income, and subjective well-being while accounting for time effects and unobserved individual eff...
