Project Overview
We use the "ignorance equivalent" approach [Müller-Itten et al, 2025] to model learning ability, and seek to better understand the interplay between personal preference traits and learning behavior. The main objectives of the project are:

• Develop numeric algorithms that efficiently determine the optimal rational inattentive choice for a range of learning cost functions.
• Use these algorithms to simulate the behavioral impact of different cost functions in concrete settings, and compare it with documented patterns of behavior.
• Design and deploy an experimental protocol that allows us to measure perceived learning costs.
• Implement the protocol in several choice experiments (both online and in the lab) to identify key features that drive the cost of learning.
• Experimentally compare perceived versus experienced learning costs to uncover potential biases.
• Identify how risk attitudes shape the agent's incentives to learn.

What to expect as a PhD student on this project:

• You will conduct innovative and high-quality research on choice with costly learning.
• You will have time dedicated to advancing your own independent research agenda.
• You will actively contribute to the project's research activities, from developing theory, running experiments and evaluating data to the drafting and publishing of academic papers.
• You will support the teaching initiatives of the team and contribute to the organization of occasional workshops.
• You will be part of a vibrant research community in the institute and the department. You are expected to attend seminars, provide feedback on other's research, and contribute to the preparation of grant proposals.
• The position is based in the beautiful city of St.Gallen, Switzerland, and requires regular presence at the department.
• The start date is flexible, but no later than August 2026.

Compensation
Compensation for this short-term position is based on the cantonal salary scales.

• A master degree (completed or near completion) in Economics or Mathematics, with a strong background in experimental economics, numerical methods and/or economic theory.
• Enthusiasm and ambition for conducting high-quality research.
• Hands-on experience with designing and running experiments (lab, online, or field) is highly desirable.
• Ability to work independently, think creatively and contribute collaboratively in a dynamic team environment.
• Effective written and verbal English-language communication and time management skills.
