Moritz is a co-founder of Brickfact. He studied economics and computer science and has a background in software development and statistics. His work at Brickfact covers set data in the app and website, as well as current offers.
Brickfact's research articles are one focus of his published work. How do estimated market values develop after a set retires? How do different years and themes compare? His articles explain the data, calculations and limitations of each analysis.
The studies distinguish changes in estimated market value from the amount a collector actually receives from a sale. Sample size, observation period and costs matter when interpreting a percentage. The studies linked below let you examine the results alongside their methodology.
