A vast literature has documented the importance of cultural beliefs and norms for economic performance. In search of the ultimate link between beliefs and prosperity, an obvious role has been suggested for religion. Evangelicalism is among the most dynamic religious movements in the world and is the fastest growing portion of Christianity. Yet despite this expansion, little is known about the evangelical movement’s expansion, especially at the individual level.

This project examines the causal impact of joining the evangelical movement on economic well-being and various other socioeconomic outcomes. The impact will be assessed using a randomized-control encouragement design.

Experimental Design

Experimental Design
Impact will be assessed using a randomized-control encouragement design. Specifically, the evaluation will exploit one of several outreach activities run by a local Pentecostal church, where members of the ministry makes personal visits to individuals and invites the visitees to attend a service run by the church. The proposal calls for randomly assigning the set of individuals who receive a visit from the members (pastors) of the ministry, without changing the number of pastors involved in the outreach or the time they spend in the field.

Experiment Characteristics

Sample size: planned number of clusters
Sample size: planned number of observations
3,000 individuals
Sample size (or number of clusters) by treatment arms
1,500 in the encouragement group and 1,500 in the control one
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
We estimate that a design with 3,000 households, assuming a 30 percentage points difference in attending service between those being invited and those not being invited, has 80% power to detect a statistically significant effect size of 0.34 standard deviations.
