Final answer:
Excellent and free financial information can be found through various sources, such as the OpenStax website and the government's FOIA portal. OpenStax's resources explain how firms choose financial capital sources based on imperfect information.
Step-by-step explanation:
Excellent and free financial information can be found through various sources. One such source is the OpenStax website, which provides educational resources, including a market overview page that contains information about financial markets.
Another source of financial information is the government's Freedom of Information Act (FOIA) portal, which allows access to government financial datasets and tools for interpretation.
Firms also raise financial capital through different sources, and one common pattern is based on imperfect information. Those who run a firm usually have more information about its potential profitability compared to outside investors. This concept is discussed in the 'How Firms Choose between Financial Capital Sources' section of OpenStax's educational resources.
