Abstract
We study the effect of increasing community monitoring on the evolution of public investment projects. Specifically, we study the impact of the launching of the website MapaInversiones in Costa Rica on the percentage of budget used and on the physical progress of public investment projects. Mapainversiones is an online platform where government agencies are required to upload information about the public investment projects they are conducting. After the release of the website, all the information about the public investment projects was available to the public. This decreased the cost of monitoring for the citizens, making it easier to check the status of the public investment projects.

Experimental Details
Interventions
Intervention(s)
In 2017 the Costa Rica Government and the Inter-American Development Bank (IADB) made an agreement to conduct a large-scale randomize control trial to study if community participation affects the performance of public investment projects. Specifically, in March 2018 the government with the support of the IADB launched a website called MapaInversiones where citizens could see geo-referenced information, make inquiries and check the progress of public investment projects. The idea behind is to reduce the cost citizens must incur to monitor the public investment in the country and to study its effect on the performance of public investment projects.

Primary Outcomes
Primary Outcomes (end points)
Budget used and Physical progress
Primary Outcomes (explanation)
The budget used is the proportion of the budget assigned that the agency has used. The physical progress is the sum of the percentage of each stage that has been completed divided by the sum of all stages multiply by 100. We assume all the stages of a projects are equally relevant.
Secondary Outcomes
Secondary Outcomes (end points)
Citizens' participation
Secondary Outcomes (explanation)
Citizens' participation is the accumulated inquiries that people do about all the projects between April 2018 and October 2019
Experimental Design
Experimental Design
On March 2018, using the list of 57 agencies we randomly select 29 agencies that should upload the information of all its projects to the website MapaInversiones on April 2018. The randomization was performed using the Stata random number generator after stratification by size of the agency. The size of the agencies is big or small. An agency is considered big if its approved budget is in the top 15 percentiles, and small otherwise. A total of 460 projects from 29 agencies were assigned to be upload to the platform and 189 projects from 28 agencies were assigned to the control group.
Experimental Design Details
The administrative data of the projects were provided by MIDEPLAN (Ministerio de Planificacion Nacional y Politica Economica, Costa Rica). There are 649 public investment projects that belongs to 57 agencies. We have data of two pre-treatment characteristics and two outcomes. The pre-treatment characteristics are time progress and approved budget. Time progress is the proportion of the original estimated time the project has completed till March 2018. It can be greater than 1 because projects can last more time that was expected. The approved budget is the budget the project has assigned on March 2018. The outcomes are budget used and physical progress.
Randomization Method
The randomization was performed using the Stata random number generator after stratification by size of the agency. The size of the agencies is big or small. An agency is considered big if its approved budget is in the top 15 percentiles, and small otherwise.
Randomization Unit
