Abstract
This study investigates the opinion of Lebanese students on bank trust in the wake of the recent Lebanese banking crisis. Using a vignette experiment, we explore the causal effects on trust of bank and deposit characteristics. Using an individual post-vignette survey, we explore how trust in banks is also associated with respondent socio-demographic characteristics and attitudinal opinions.

Experimental Design

Experimental Design
Each vignette consists of a short description of an agent who asks for advice on the best bank where to deposit an extra income.

Respondents will be asked which bank they would advise the agent to go to, as well as other solutions they would advise the agent to use.

The factors included in the vignette design echo major determinants of bank trust:
• Bank characteristics
• Deposit characteristics

Each student will randomly be assigned 1 version out of the 16 possible versions of the vignette.

After the vignette, a post-experimental individual survey collects information on sociodemographic characteristics and opinions.
Experimental Design Details
Randomization Method
Each individual respondent randomly received a version of the vignette among the pool of 16 alternative versions of the vignette. Randomization will not be stratified.
Randomization Unit
Randomization Unit is : individual students.
Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of clusters
No clustering of treatments.
Sample size: planned number of observations
1,600 individual students
Sample size (or number of clusters) by treatment arms
approximately 100 students
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Estimated number of respondents by version is about 100. This is consistent with an acceptable predictive power (5 % significance level, 80 % power and medium size effects, h=0,5).
