What is Choice Modelling?
(and what are Choice Experiments?)
Choice Modelling is a scientific methodology used by academics, economists and policy-makers to measure preference. It is regarded as the most scientifically robust method to investigate and understand how choices are made.
Understanding the level and nature of the demand for products or services is as critical for new healthcare treatments as it is for transport planning and environmental policies.
It can answer…
- How do people trade off the risks of a new health treatment against the benefits?
- How should future transport in cities be planned for with new mobility options?
- When my customers buy from me, what aspects of my product and services are influencing them?
Choice modelling is frequently accompanied by a Choice Experiment when real-world data is weak or non-existent.
This is a systematic and planned experiment, applied to respondents within a survey and used to generate preference data from hypotheticial scenarios.
A short video on creating a choice experiment is here.
Choice Modelling is used in..
- Major transport and infrastructure projects to predict and plan route choice
- Non-interventional Clinical Trials to provide real-world evidence as to the adoption and adherence to new treatments.
- Environmental Policy development to balance the needs of conservationalists, tourism and farming.
Visit the academic publications page for more information on formal uses.
There has been a steady increase of in the number of academic papers citing choice modelling past ten years.
Following a recent approval of choice methods in clinical trials by the US Food and Drug Administration we are seeing a shift in focus to more applied use.
