Finantsmajandus

Finantsmajandus, or financial economics, is a field of study within economics that examines how individuals, firms and institutions allocate capital over time under uncertainty. It investigates the pricing of financial assets, the functioning of financial markets, and the mechanisms through which information, risk and liquidity affect investment decisions and economic activity. The discipline connects theory with empirical analysis to understand how prices reflect expectations of future cash flows and risk, and how financial intermediation channels savings into investment.

Key subfields include asset pricing, which studies why assets trade at certain prices and returns (including models such as the capital asset pricing model and multi-factor frameworks); corporate finance and capital structure, which analyze how firms decide on funding and investment; and market microstructure, which looks at how trading rules, liquidity, order flow and transaction costs shape prices. Financial econometrics applies statistical methods to financial data, while derivative pricing covers options and other contingent claims. Risk management, portfolio theory, and financial regulation address risk, diversification, and the stability of financial systems. Behavioral and experimental finance address how psychology and biases influence market outcomes.

Finantsmajandus has practical relevance for investing, corporate decision-making, banking, insurance, and policy. It relies on mathematical models and empirical data, yet remains attentive to real-world frictions and systemic risk. Education in this field typically combines economics, statistics, econometrics, and finance.
