We randomize the promotion of a program that helps workers making less than the monthly minimum wage in Colombia order to encourage enrollment. We use random assignment to the treatment to evaluate the effect of signing up for the program on savings for old age through the program, other financial savings, saving in non-financial assets, labor supply, and consumption.

Experimental Details


We designed, with the colombian public pension administrator (COLPENSIONES), an RCT to evaluate the socioeconomic effects of a new old age protection policy in Colombia, called Social Protection Floor (SOCPRO). We randomize the timing and the way we're going to get in touch with 72013 people previously identified as SOCPRO prospects, to encourage them to start saving for their old age through this new program. Also, after the intervention, we conduct a survey among the full sample, so we can identify those SOCPRO´s socioeconomic effects in its affiliate's daily lifes.

Experimental Design

Experimental Design
This RCT requires 2 stages. The first one consists in sending a stimulating message (via phone call, SMS or both) to a sample of people previously identified as SOCPRO viable prospects in our database, to encourage them to start saving or increase their old age savings.
So, the fist stage results are mainly about these saving variables. But, since we want to analyze other outcomes as labour supply, income, debt, among others, we perform a second stage which consists in applying a survey on both the treatment and control groups. These second stage must be applied at least a month after performing the first stage on the treatment group, so we can perceive the first stage consequences.
