• use database engines SQL, MongoDB, Redis
• interfaces for
  • structured data from CRSP, Compustat, IBES, TAQ
  • APIs from ALFRED, BEA
  • unstructured data from SEC Edgar, Federal Reserve websites
  • academic websites by Ken French, Loughran and MacDonald, Hoberg and Phillips
• recipes for econometrics, finance, graphs, event studies, backtesting
• applications of statistics, machine learning, neural networks and large language models
