Field experiment

In this experiment, we hired workers to help us with a mail sorting task. Workers were randomized to one of three conditions. (a) fixed-wage with standard speech, (b) fixed-wage with standard speech plus possibility to earn extra money if workers pass a certain production threshold, and (c) fixed wage with charismatic speech. We observed the quality and quantity of work done (refer to working paper for details).  

See below for a full version of the speeches

Here is a short version for demonstration purposes with mark-up of tactics; we have clipped similar content from the speeches and play them one after the other. Click here to view

Lab experiment 1

Brief description: In this lab experiment, participants played a standard public goods game. They took decisions over 10 rounds with respect playing their endowment in a public or private account. Players are given 20 points as endowment each round (30 points = 1 Swiss Franc). Their earnings are determined by personal account points + .4*total points (of all group members) in the public account. Players observe decisions of group members after every round. We measure their beliefs (of what they think others will do) and their actual contributions. In this experiment we randomized participants to one of three groups (a) control (no speech), (b) standard speech and (c) charisma speech. For the conditions in which participants saw a speech, they viewed the speech individualy.

Lab experiments 2 and 3

Brief description: The set-up is the same as the above; however, the speech is slightly altered and the experimentors donate money to the Lausanne children’s hospital as function of total player contributions. Here we have only two conditions, standard or charismatic speech (no control condition).

We ran this experiment with two independent pool of participants. In the first pool (experiment 2), participants viewed the relevant speech alone. In the second pool (experiment 3), participants watch the speech together in groups.
