Experiments

Some of Nudge Lebanon’s key interventions include:

 

Electricity2.png Improving Timely Payment of Electricity Bills To improve response to payment of utility bills, Nudge Lebanon conducted an experiment in collaboration with Electricité du Liban whereby simple nudge messages were added to the reminder slips, improving timely payment by up to 15%, compared to the control group which received the traditional reminder slip.
Seatbelt Icon.png Increasing Seatbelt Use To increase seatbelt use, NudgeLebanon in collaboration with the Four Seasons Hotel nudged vehicle occupants using the valet parking service at the hotel by delivering a verbal prompt to drivers as they enter their cars reminding them to fasten their seatbelt, leading to an increase of 82.8% in drivers’ seatbelt compliance in the treatment group compared to the control which did not receive any prompt.
Plastic Cutlery.png Reducing Demand for Plastic Cutlery with Delivery Orders To reduce the amount of plastic cutlery dispensed with delivery orders, Nudge Lebanon collaborated with a local restaurant in Beirut to implement a timely nudge that gave customers the option to opt-out of receiving the cutlery if they did not need it. This simple nudge led to a reduction of around 78% in the demand for cutlery compared to the baseline.
Recycling.png Increasing the Use of Communal Glass Recycle Bins To increase the uptake of glass recycling, Nudge Lebanon, in collaboration with Cedar Environmental, implemented three consecutive interventions to increase the utilisation of two communal recycling bins located in the Hamra area of Beirut. The interventions consisted of 1) replacing the opaque front side of one of the bins with a transparent one; 2) changing the artwork covering the two bins, and 3) prefilling the see-through bin with a small but visible amount of glass. All three interventions revealed a negative relationship between bin transparency and compliance.
foodwaste.png Increasing Demand for Leftover Food To reduce food waste in restaurants, Nudge Lebanon in collaboration with a group of students enrolled in a Behavioral Economics course jointly offered with the American University of Beirut, designed a simple two-sided colored token that defaulted diners into taking their leftover food away. The intervention led to a 26% increase in the demand for leftover food relative to the baseline period.
Recycling.png Increasing Reuse of Eco-bags at a Large Chain Supermarket To reduce the use of plastic bags, Nudge Lebanon, in collaboration with a group of students from the American University of Beirut, increased the use of eco-bags among customers who regularly shopped at a large chain supermarket, by sending them weekly SMS reminders. Regular customers who received the reminders were 8 percentage points more likely to reuse their eco-bags compared to the control group. These effects persisted several weeks following the initial reminders.

Nudge Lebanon is also involved in many other experiments that address various challenges related to traffic, corruption, recycling, smoking, etc.
