Experimental Design
In Part 1, we will elicit respondents’ beliefs and attitudes around solar power and perceived behavioral control around solar installation. More specifically, following the best practice guidance provided by Fuster and Zafar (2021) and Haaland et al. (2021), the subjective beliefs that we would solicit from firm decision-makers would include the following, which will be elicit pre- and post-treatment:
- Respondents’ expected time frame for investing in solar energy
- Respondents’ overall feelings toward solar energy
- Respondents’ perceptions of the usefulness of solar in case only partial energy requirements are covered
- Respondents’ knowledge about the initial cost of solar energy
- Respondents’ perception about the ease of technical integration of solar systems with grid electricity and generator usage
- Respondents’ concerns about having sufficient roof/land space
- Respondents’ comfort regarding the installation/maintenance costs
- Respondents’ comfort regarding the ability to finance
- Respondents’ comfort with the affordability of monthly payments
We will also elicit personal preferences (including risk preferences and loss aversion measures), related expectations (macro expectations and expected electricity price increases), and control variables (current energy usage).
In Part 2, respondents randomly assigned either to a control group or to one of two information treatments will watch a short video. For the two treatments, the targeted information will be communicated peer-to-peer, featuring the narrative of a local factory owner who has successfully transitioned to a solar energy system. The treatment videos will break down the calculations and explain the installation and maintenance costs, savings, roof space requirements, financing options, and the ability to integrate solar with existing energy sources. The control video will feature the narrative of a local food processing factory owner who has successfully navigated the Covid period. The video also discusses industry trends in product and process innovation.
In Part 3, we will re-elicit respondents’ beliefs and attitudes around solar energy and the intended likelihood of purchasing it. We will ask for some additional beliefs post-treatment that we did not ask for pre-treatment. These are:
- Respondents’ intention to make an inquiry from a solar installation firm within the next 6 months
- Respondents’ access to further information about solar energy via a QR code provided at the end of the survey.
- Respondents' knowledge about solar energy usage by other firms in the same sector;
- Respondents’ knowledge about the impact of a solar energy investment on an average firm’s electricity bill savings (q. F1)
- Respondents’ perception about the future payback period (in years) until the investment in solar is recouped (q. G1)
- Respondents’ perception about the impact of solar investment on their customer base
In Part 4, we will ask a comprehensive battery of socio-demographic and standard firm characteristics. Based on the results of the analysis and on the available financial resources, we will try to investigate the longer-term impacts of information provision on beliefs, intentions, and actual purchasing behavior from the same respondents in a follow-up survey three to six months later.
The primary data collected through this survey tool will allow us to carry out two main types of analysis. First, we will be able to examine how respondents’ preferences, prior beliefs and attitudes over solar power affect the likelihood of investing in this renewable energy. We will look at how the relative contribution of structural and behavioral barriers in hindering the adoption of solar energy across small-medium enterprises in central Punjab changes across different sectors and generations. Second, our field experiment embedded in the survey will allow us to compare the average likelihood of purchasing solar energy across different treatment groups and test whether objective information provision is effective at changing attitudes towards solar energy and intentions to purchase it. Overall, by providing a better understanding of SME managers’ decision-making process, the study will help policymakers design more effective policy instruments to support the market deployment of renewable energies such as solar power.
