Abstract
The primary goal of this project is to evaluate the extent to which supply side and demand side interventions are complementary or substitutable in the context of farm mechanization. To do so, we implement a randomised controlled trial with four treatment conditions: 1) control arm; 2) demand side subsidy; 3) supply side service provider bundled intervention; and 4) the combination of both the supply side service provider intervention as well as demand side subsidy. The bundled supply-side intervention includes both a loan component and maintenance support services, and is randomised at the provider-level, while demand-side interventions are randomised at the household-level within kebeles in which the selected providers operate.

We will examine the impact of these interventions on a range of outcomes. On the farmer side: to begin we will measure the differential impact of the three interventions on the adoption of small mechanisation services. Assuming adoption, we will then examine the impact on labour outcomes. Throughout we intend to examine the disaggregated impacts on men and women, and youth. On the service provider side: we will examine the impact on service diversification, firm seasonality, and firm revenues.

Primary Outcomes

Primary Outcomes (end points)
Household level: Farm mechanisation service adoption (i.e. use of 2WT for threshing, irrigation and/or harvesting), Time use during relevant seasons
Service provider level: Number of services offered, number of months operational, number of customers served

Experimental Design

Experimental Design
Due to the focus on firm strengthening and service expansion on the supply side, we will restrict our sample to areas already within the existing market area of service providers. In each of the 140 kebeles, we will obtain the household rosters from the kebele manager and randomly select 10 active-farming households to participate.
Experimental Design Details
Not available
Randomization Method
Randomization done in office by a computer
Randomization Unit
Randomization of service provider to the supply-side intervention will be conducted at the service provider level.
Randomization of households to the demand-side intervention will be at the household level, stratified by the supply-side intervention.
Was the treatment clustered?
No
