What’s financial economics?

The field of financial economics examines the allocation of resources in markets. Future events, whether linked to stocks, portfolios, or the market, are routinely considered in financial decisions.

How does it work?

Financial decisions may be difficult. Time, uncertainty, opportunity costs, and information can provide incentives or disincentives. Financial economics uses economic theory to assess how specific factors affect decision-making, helping investors make intelligent choices.

Financial economics uses complex models to examine decision factors. These models often presuppose rational decision-makers; however, this is not always true. It must consider party irrationality as a risk factor.

This field of economics relies significantly on microeconomics and fundamental accounting ideas. It is a quantitative field that uses econometrics and other mathematical methods.

Understanding fundamental probability and statistics is essential for financial economics, as they are the primary instruments for risk assessment.

This examines fair value, risk, returns, and asset financing. Monetary considerations such as interest rates and inflation are also considered.

Financial vs. Traditional Economics

Traditional economics emphasizes money-only interactions. In contrast, it focuses on trades when both parties may have different types of money.

Financial economists differ from classical economics by focusing on monetary activities, including time, uncertainty, alternatives, and information.


There are different perspectives on this. Two notable examples are:


Time-based decision-making acknowledges that $1 held less worth in 10 years than now. The $1 at ten years must be discounted due to risk, inflation, and the fact that it is in the future. Incorrect discounting might result in underfunded pension programs.

Manage Risk and Diversify

Financial product ads for the stock market should warn purchasers that investment values might fluctuate.

Financial institutions strive to insure or hedge this risk. Holding two high-risk assets might reduce total risk if share A performs poorly when share B performs well (and vice versa), creating a perfect hedge.

An essential facet of finance is calculating the total risk of a portfolio of hazardous assets, which may be smaller than the individual components.


  • Market resource utilization and distribution are studied in financial economics.
  • According to economic theory, time, risk, opportunity costs, and knowledge can influence decision-making incentives or disincentives.
  • They use complex models to examine decision factors.
