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...

This paper implements the answer-copying detection methodology for multiple-choice tests developed in Sotaridona, van der Linden and Meijer [2006], based on Cohen's Kappa index. We present results of this methodology applied to the standardized test for college admissions in Colombia that took...

Multiple choice exams are frequently used as an efficient and objective instrument to evaluate knowledge. Nevertheless, they are more vulnerable to answer-copying than tests based on open questions. Several statistical tests (known as indices) have been proposed to detect cheating but to the...

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...

Este trabajo implementa la metodología de detección de copia en exámenes de múltiples opciones expuesta en Sotaridona, van der Linden y Meijer [2006] basada en el índice Kappa de Cohen. Presentamos los resultados de aplicar esta metodología a las pruebas del Estado ICFES 2009 II. Este es,...

There has been so much debate on the increasing use of formal methods in Economics. Although there are some studies tackling these issues, those use either a little amount of papers, a small amount of scholars or a short period of time. We try to overcome these challenges constructing a database...

We introduce new risk groups to a standard capitation formula and evaluate risk selection incentives of insurers. The study uses a unique data set of almost 24 million affiliates to Government’s mandatory health insurance system. This data set is very rich in the sense of reporting all claims...
