Professor Mark Armstrong

BA, MPhil, DPhil, FBA
University Academic Fellow since 2011
Professor of Economics
I work mostly on topics concerned with the operation of markets. This includes research on how firms chooses their prices, including issues to do with offering discounts when consumers buy multiple units or products, or when consumers care about how many other customers also choose to buy from the firm, and how consumers search for products and prices. Particular markets studied include telecommunication and media, scientific publishing, markets for "market information", and markets where some consumers can be "pressured" into buying.
