Abstract
This study investigates the opinion of Lebanese students on the attitudes towards corruption in a general parliamentary election. Using a vignette experiment, we explore the causal effects of i) the nature of corruption, ii) the nature of the voter’s prize, iii) factors of proximity with the respondent. Using an individual post-vignette survey, we explore how attitudes towards corruption is associated with the respondents’ socio-demographic characteristics and attitudinal opinions.

Experimental Design

Experimental Design
Each vignette consists of a short description of a hypothetical voting choice. In a general election setting, the respondent is presented with two candidates who vary in their personal characteristics and corruption level.

The factors included in the vignette design echo major determinants of the acceptability of corruption:
• the nature of corruption
• the proximity of the respondent and the candidate

Respondents are asked about
• the candidate they would choose to vote for (ordinal ranking);
• their general appreciation of both candidates (7-rank majority judgment)

Each student will be randomly 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
1600 individual observations.
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).
