This trial is based on or builds upon one or more prior RCTs.
This evaluation examines the impact of the Complementary Livelihood and Asset Support Scheme (CLASS) - a multi-component productive inclusion intervention on poor, social safety net program beneficiaries in Ghana. To be carried out by the government, the treatment comprises of the provision of microenterprise skills training, start-up lump sum cash grants, mentoring and coaching, and financial inclusion activities. In line with the Graduation Approach, the program seeks to durably lift beneficiaries out of extreme poverty. The evaluation will be based on a randomized phase-in design, with randomization into phases performed at the community level. Impact will be evaluated by comparing outcomes at baseline and at follow-up and between batch-2 and batch-3 communities. Treatment is expected to be staggered by at least one year.

Experimental Details


The Complementary Livelihood and Assets Support Scheme (CLASS) facilitates income generation activities (IGAs) for 30,579 beneficiaries from the Labor-Intensive Public Works (LIPW) program and the Livelihood Empowerment Against Poverty (LEAP) cash transfers program. Under CLASS, the Ministry of Local Government, Decentralization and Rural Development (MLGDRD) will first carry out market feasibility studies of various livelihoods projects and through its zonal offices, the ministry will facilitate the selection of communities and households to undertake productive activities in selected projects. Selected individuals will benefit from life skills and micro-enterprise skills trainings; provision of start-up lump sum cash grants; and mentoring and coaching.

Primary Outcomes

Primary Outcomes (end points)
Micro-enterprise productivity and incomes; Local employment; Household expenditure in health and education expenditure; and Women’s empowerment.
Primary Outcomes (explanation)
Since the intervention offers cash grants to invest in income generating activities (IGA) such as goat rearing, individual enterprise productivity will be measured through marginal profit from each dollar invested in an IGA. Beneficiary and household incomes will be measured through self-reported surveys and monitoring reports from the implementing agency. Local employment will be measured through comparisons between baseline and endline, non-household employment shares of the average micro-enterprise. Women’s empowerment will be measured through participation in community leadership and household decision-making before and after the intervention.

Experimental Design

Experimental Design
The intervention will be implemented in three phases. Phase one will target 136 (out of 455) communities to receive the treatment while phases 2 and 3 each target 153 and 206 communities, respectively. Phase 2 and 3 communities will serve as the evaluation communities from which baseline community, individual, and household surveys will be conducted. Per sample and power calculations, the experiment requires a minimum of 180 communities (and 15 individuals per community). As such, 180 communities are randomized into the experiment - 90 treated (batch 2) and 90 control (from batch 3). The baseline survey is conducted from all 180 communities (2,700 individuals). After the baseline surveys are completed, the intervention can be initiated in 90 of them (batch 2) towards the end of 2021. The remaining 90 experimental communities are left untreated until at least the end of 2022 (or 1 year after the end of the treatment of batch 1 communities).

Experiment Characteristics

Sample size: planned number of clusters
180 communities
Sample size: planned number of observations
2,700 households
Sample size (or number of clusters) by treatment arms
90 treated communities (1350 households), 90 control communities (1350 households)
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Using the latest round of the Ghana Living Standard Survey (GLSS 7), we estimate the control-group mean household food consumption in the northern regions of Ghana to be GHC349.09/month with a standard deviation of GHC164. After the intervention, we expect our sample to detect a minimum of 6 percent increase in household food expenditure among households in treated communities. The intra-cluster correlation used corresponds to 0.016, which was used in an impact evaluation of a related program in the same region in 2016 (see pre-analysis plan for details).
