Abstract
In this project, we will study through a randomized controlled experiment whether misperceptions about peers' investments in schoolwork play a role in explaining why some students -- mostly low achievers -- spend relatively little time on schoolwork.

Primary Outcomes

Primary Outcomes (end points)
At the end of our survey, participants are asked about how much time they plan to spend on homework during the following months until they complete 10th grade. This is the basis for the first primary outcome, 'Planned study time': midpoint value of the study time interval chosen by students. We will also use an alternative specification with a dummy variable indicating whether students report an intended study time equal or higher than the (baseline) median study time in their class.

In addition, at the end of the survey we will use a standard incentivized Becker-DeGroot-Marschak multiple price list procedure to elicit a truthful measure of students' willingness to pay for a text-messages coaching program aimed at helping them remember and achieve their schoolwork goal. This forms the basis for our primary behavioral outcome, 'Behavioral measure': Students willingness to pay for a motivational text-messages program.

Experimental Design

Experimental Design
In this project, we will study through a randomized controlled experiment whether misperceptions about peers' investments in schoolwork play a role in explaining why some students -- mostly low achievers -- spend relatively little time on schoolwork.
Experimental Design Details
Randomization Method
The randomization will be at the class level and stratified within schools. For each school participating in the study, before the intervention, we will randomly select treated and control classes. For schools with an even number of volunteer classes, we will form strata of two classes based on the consent rate within each class. For schools with an odd number of volunteer classes, we will first randomly select which strata will be made of three classes, and then form one strata with three classes and remaining strata of two classes based on the consent rate within each class. For strata with two classes, half of the classes will be randomly selected for the treatment condition. For strata with three classes, we will first randomly select whether two or three classes will be assigned to the treatment condition. In a second step, classes will be assigned for the treatment condition on a random basis.
