Abstract
We are conducting a large-scale randomized field experiment in Hungarian schools that randomly assigns desk-mates to students within classrooms. We investigate whether desk-mates affect students’ cognitive and affective academic self-concept.

Experimental Details
Interventions
Intervention(s)
We randomly assigned desk mates to students within classrooms. All students within a classroom were randomly assigned to free-standing two-person desks via unconstrained random partitioning. Teachers were instructed to employ the intended seating chart in three subjects—mathematics, Hungarian literature, and Hungarian grammar—for the duration of the fall semester 2017.

Our primary treatment variables are desk mate's baseline (Spring 2017)grades and GPA in math, literature, and grammar.
Intervention Start Date

Intervention End Date

Primary Outcomes
Primary Outcomes (end points)
Three measures of average absolute cognitive academic self concept (ASC), relative cognitive ASC, and affective ASC.
Primary Outcomes (explanation)
Secondary Outcomes
Secondary Outcomes (end points)
School-subject specific absolute cognitive ASC and relative cognitive ASC in math, language, and grammar.
Secondary Outcomes (explanation)
Experimental Design
Experimental Design
We execute a large-scale randomized field experiment in 195 classrooms of 41 Hungarian primary schools. The intervention consists of randomizing the seating chart within each classroom at the beginning of the 2017 fall semester and encouraging adherence until the end of the semester in January 2018. Endline outcomes data are collected and will become available to the research team in late May 2018.
Experimental Design Details
Randomization Method
Within each classroom, we assigned students to free-standing two-person desks via unconstrained random partitioning. Randomization was based on Spring 2017 class rosters, using a computer. To account for entries and exits from the Spring class roster, we stipulated a replacement algorithm and defined the "intended seating chart" as the randomized seating chart after the application of the replacement algorithm.

Experiment Characteristics
Sample size: planned number of clusters
Approximately 3,800 students in 195 classrooms of 41 schools.
Sample size: planned number of observations
Approximately 3,800 students.
Sample size (or number of clusters) by treatment arms
This is a networked trial for peer effects. We analyze the outcomes of approximately 3,800 students. Each student is both subject in the analysis and serves as the peer for his or her desk mate.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
