Prompt
Create a realistic portrait of Paul Robert Milgrom, a middle-aged American economist with a distinguished appearance, sitting in a professional setting, possibly in front of a bookshelf or a Stanford University backdrop, reflecting his contributions to microeconomics, auction theory, game theory, and market design; he should be dressed in formal attire, exuding a sense of authority and intellectualism, with a subtle hint of a smile, capturing his achievements and notable awards, including the Nobel Prize in Economics, which he received in 2020 for his improvements to auction theory and inventions of new auction formats.
