Matemática
Ok, economia não é só matemática. Mas o que você precisa saber de matemática não é pouco, certo? Certo.
Quer ter sucesso como economista? Então uma parte de seu tempo será com a matemática. Siga a sugestão de um gigante da Macroeconomia: Thomas Sargent.
E já que meu irmão quer falar de inteligência artificial (o outro Leo, nos comentários a um post de outro dia), aí vai um trecho de uma entrevista com Sargent, em 1989:
Region: What are you working on personally these days?
Sargent: A couple of things. I'm working on artificial intelligence, taking some models of macroeconomics and instead of saying that people are rational, we assume that they're artificially intelligent. I'm doing this with some colleagues, Ramon Marimon and Ellen McGrattan. What we've done is gone to the literature on artificial intelligence. We met a man named John Holland who is a distinguished computer scientist at the University of Michigan. He's developed models of the way people learn from the environment. So people start out not being rational, not understanding how the world works. They start out being very stupid. One of the hardest problems in artificial intelligence is to figure out how to make computers learn. People seem to learn much faster than computers can and much better. Holland has, from our point of view, discovered some of the most exciting algorithms for creating computer programs that will learn. Instead of assuming rationality, we endow our people with these little computer programs and then see what happens. And what's happened in a lot of situations is that they end up learning and being rational.
