Abstract
This study explores how gender affects communication between borrowers and lenders. In partnership with a bank in Afghanistan, we invited micro-entrepreneurs to apply for small loans. Each applicant was randomly informed that their application would be reviewed by either a male or a female loan officer. The applications included standard financial details and a short written explanation of why the borrower’s ability and willingness to repay the loan could be trusted, which we refer to as borrower narratives. By comparing how male and female officers evaluated these narratives, we examine whether women communicate less effectively when the loan officer they face is male. The findings will help us understand how communication barriers contribute to gender gaps in access to finance and how increasing the number of female officers might reduce these disparities.

Interventions

Intervention(s)
This study examines how borrowers’ written communication in small-loan applications influences loan officers’ evaluations and actual lending outcomes at a partner bank. Eligible micro-entrepreneurs complete standardized, collateral-free loan applications that include a short narrative describing their ability and willingness to repay. Each applicant is informed that their loan will be reviewed by either a male or a female loan officer, with the assigned officer gender determined randomly. All applications are anonymized before review so that loan officers cannot see any borrower identifiers. Loan officers evaluate applications using the bank’s regular scoring procedures, and loan decisions are based on these evaluations. After the evaluation phase, officers complete a short follow-up survey about their review experience. Some details of the study design are temporarily withheld to preserve research integrity and will be made public once data collection and analysis are complete.
Intervention (Hidden)
The intervention is designed to test whether (1) the informational value of borrower-written narratives in small-loan applications varies with the gender of the assigned loan officer, and (2) whether post-evaluation exposure to borrower gender information amplifies gender-based stereotypes among officers.

The study is implemented in partnership with a commercial bank in Afghanistan that issues standardized, collateral-free microloans to eligible small business owners. The intervention consists of two main stages:

Stage 1: Loan Application and Review Process

Eligible micro-entrepreneurs are invited by the partner bank to apply for a standardized, non-collateralized small loan with fixed, non-negotiable terms. Each application includes standard hard information (business characteristics, repayment history, etc.) and an open-ended narrative where applicants explain, in their own words, why the bank should trust their ability and willingness to repay.

At the time of application, all applicants are informed that their loan will be reviewed by either a male or a female loan officer. The gender of the assigned officer is randomly determined by the research team and displayed on the application. Applicants are unaware that the officer’s gender assignment is part of a randomized design.

Each loan application is anonymized before being evaluated, meaning that all identifying details—including names, photos, and any gender-indicative information—are removed. Each application is then evaluated by multiple loan officers under two randomly assigned review conditions:

Narrative Visible: The officer sees the full application, including the borrower’s open-ended narrative.

Narrative Concealed: The officer sees the same application, but the narrative section is removed.

Officers assign standardized repayment-likelihood scores in both cases. These scores are used by the partner bank to make real loan approval decisions, ensuring that evaluations have real economic consequences. By comparing each application’s mean scores across visible and concealed conditions, we identify the marginal informational value of the narrative. Comparing these effects across the randomized officer-gender assignments allows us to test whether female borrowers’ narratives have lower informational value when the assigned officer is male.

Stage 2: Post-Evaluation Survey (Officer Follow-up)

After all reviews and loan decisions are completed, loan officers participate in a short post-evaluation survey. Each officer receives a private report listing the applications they reviewed and the scores they assigned. For a randomly selected half of officers, the report also reveals the true gender of each borrower. For the other half, gender remains undisclosed.

The survey elicits officers’ beliefs about borrower credibility, communication ability, and repayment quality, as well as self-assessed confidence in their own scoring. Comparing responses between these two groups allows us to test whether exposure to borrower gender information ex post amplifies gender-stereotypical beliefs, particularly among male officers.

Primary Outcomes

Primary Outcomes (end points)
Evaluation Score (Likert scale, 1 to 10)
Primary Outcomes (explanation)
The primary outcome is the loan officer’s evaluation score, measured on a scale from 1 to 10, reflecting how likely they believe the applicant is to repay the loan by the maturity date, where 1 indicates “very unlikely to repay.”

Experimental Design

Experimental Design
This study examines how written communication in loan applications affects how applicants are perceived by loan officers. We collaborate with a financial institution to collect anonymized loan applications that include a short open-ended section where borrowers describe their credibility and repayment ability. Professional loan officers evaluate these applications, and the bank’s lending decisions are based on these evaluations. To protect privacy, all applications are anonymized before review, and loan officers cannot see any borrower information that reveals gender or identity. The study aims to better understand how borrower communication influences officers’ assessments. More details of the study are temporarily withheld to preserve the integrity of the research and will be made public once the study concludes.
Experimental Design Details
This study tests whether the marginal informational value of borrower-written narratives in small-loan applications varies with the gender of the officer assigned to review the file. In partnership with a commercial bank in Afghanistan, adult micro-entrepreneurs complete a standardized, collateral-free application that includes a short narrative justifying willingness and ability to repay. Each applicant is informed that their application will be reviewed by either a male or female loan officer, with the assigned officer gender randomly determined by the research team and displayed on the application. All applications are anonymized prior to review, and loan officers cannot view borrower names, photos, or any identifying information that implies gender.

Each application is scored by multiple officers under two randomly assigned conditions at the officer-application level: Narrative Visible versus Narrative Concealed. Officers provide standardized repayment-likelihood scores that the partner bank uses in its real lending decisions under fixed, non-negotiable terms. For each application, the difference in mean scores across visibility conditions identifies the marginal informational value of the narrative; comparing this across the randomized officer-gender assignment allows us to test whether narratives written by female borrowers lose effectiveness when the assigned officer is male.

Following the evaluation phase, we conduct a post-review survey to assess whether exposure to borrower gender information shapes or amplifies officers’ gender-related beliefs about borrower quality or communication ability. Each loan officer receives a summary report listing the applications they reviewed along with the scores they assigned. For a randomly selected half of the officers, the report also includes the gender of each borrower; for the other half, gender remains undisclosed. Comparing responses across these groups allows us to test whether communication frictions arising from facing a loan officer of a different gender can partly explain loan officers’ gender-based stereotypes about borrowers, particularly among male officers.
Randomization Method
Randomization is conducted in the office using a computer program.
Randomization Unit
Borrower-level randomization:
The gender of the officer shown to applicants (“male officer” vs. “female officer”) is randomized at the individual borrower application level.

Officer–application-level randomization:
The narrative visibility condition (“Narrative Visible” vs. “Narrative Concealed”) is randomized independently for each officer–application pair.

Officer-level randomization:
In the post-evaluation survey stage, whether borrower gender is revealed in the officer’s feedback report (“Gender Revealed” vs. “Gender Hidden”) is randomized at the officer level.
Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of clusters
Approximately 300 borrower applications (individual-level randomization, not clustered) and 50 loan officers (clustered randomization for post-evaluation survey stage).
Sample size: planned number of observations
15,000 applicant-officer
Sample size (or number of clusters) by treatment arms
Borrower-level treatment (unit = application; not clustered)

Officer gender shown = Male:
Planned invitations: 250 borrowers (≈ half female, half male overall sample stratified by borrower gender)
Expected completed applications: ≈150

Officer gender shown = Female:
Planned invitations: 250
Expected completed applications: ≈150

Note: Total invitations = 500 (250 female, 250 male). Expected completed applications ≈ 300 in total, with ≈ 150 per arm.

************

Officer–application condition (unit = officer–application evaluation; not clustered)

Narrative Visible: approximately 50 percent of officer–application evaluations

Narrative Concealed: approximately 50 percent of officer–application evaluations

Exact counts depend on the final number of evaluations per application. The split is designed to be 1:1 across all officer–application observations.

************

Post-evaluation survey treatment (unit = loan officer; clustered at officer level)

Borrower gender revealed in officer report: 25 clusters (officers)

Borrower gender hidden in officer report: 25 clusters (officers)

Total officers = 50, randomly assigned 25/25 across the two survey arms.
