|May 2019||Designing Effective Teacher Performance Pay Programs: Experimental Evidence from Tanzania|
with Isaac Mbiti, Mauricio Romero: w25903
We use a field experiment in Tanzania to compare the effectiveness on learning of two teacher performance pay systems. The first is a Pay for Percentile system (a rank-order tournament). The second rewards teachers based on multiple proficiency thresholds. Pay for Percentile can (under certain conditions) induce optimal effort among teachers, but our threshold system is easier to implement and provides teachers with clearer goals and targets. Both systems improved student test scores. However, the multiple-thresholds system was more effective in boosting student learning and is less costly.
|July 2018||Inputs, Incentives, and Complementarities in Education: Experimental Evidence from Tanzania|
with Isaac Mbiti, Karthik Muralidharan, Mauricio Romero, Constantine Manda, Rakesh Rajani: w24876
We present results from a large-scale randomized experiment across 350 schools in Tanzania that studied the impact of providing schools with (a) unconditional grants, (b) teacher incentives based on student performance, and (c) both of the above. After two years, we find (a) no impact on student test scores from providing school grants, (b) some evidence of positive effects from teacher incentives, and (c) significant positive effects from providing both programs. Most importantly, we find strong evidence of complementarities between the two programs, with the effect of joint provision being significantly greater than the sum of the individual effects. Our results suggest that combining spending on school inputs (which is the default policy) with improved teacher incentives could substanti...
