Abstract
The general objective of this study is to investigate variations in willingness-to-pay for time-saving lunch services in the context of the workday.
The aim of this experiment is to determine whether changes in meal break duration, schedule leniency and time pressure affect willingness to pay for time-saving lunch services during the workday. Based on hypothetical scenarios, participants will be asked to state how much they would be willing to pay to reduce waiting time to get their lunch.

Primary Outcomes
Primary Outcomes (end points)
Variations in willingness to pay
Primary Outcomes (explanation)
Secondary Outcomes
Secondary Outcomes (end points)
Variations in willingness to pay based on whether respondents felt they had to rush to answer questions
Secondary Outcomes (explanation)
Decision-making literature shows that being under time pressure affect respondents' choices. As a result, although this expriment does not seek to induce time pressure in respondents, one question was added to control whether respondents felt they were rushed to answer. If enough respondents indicate that they were and enough indicate that they were not, their willingness to pay will be compared to assess possible effect of time pressure.
Experimental Design
Experimental Design
We designed an experiment where participants are presented hypothetical scenarios relating to lunchbreak. Duration of break, leniency of schedule and time pressure were manipulated following a 2*2*2 design, as they are distinct, albeit closely related, concepts.
After reading the scenario, participants were asked to state how much they would be willing to pay to reduce delivery time of their meal. Two levels of delivery time were presented each time. Design is within-subject.

No
Experiment Characteristics
Sample size: planned number of clusters
No cluster
Sample size: planned number of observations
Sample size will be determined after running a pilot, as standard deviation of willingness to pay for this study cannot be inferred from previous studies. Variance found in pilot will be used to determine sample size.
Sample size (or number of clusters) by treatment arms
As this experiment follows a within-subject design, sample size by treatment arms is equal to planned number of observations.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
