Ostovoiman

Ostovoiman is the Finnish term for purchasing power, the capacity of money held by an individual, household, or economy to buy goods and services at current prices. It reflects the real value of income after adjusting for price levels and is a central measure of living standards in macroeconomics and everyday budgeting.

Etymology: The word combines ostaa, to buy, and voima, power or force, indicating the ability to purchase. The genitive form ostovoiman is used when discussing changes or levels of purchasing power, for example ostovoiman kehitys.

Measurement and related concepts: Purchasing power is usually assessed via real income, which equals nominal income adjusted for inflation or price indices such as the consumer price index (CPI). Purchasing power parity compares ostovoima across countries by equalizing price levels.

Determinants: Ostovoima is driven by wages and salaries, taxation and social transfers, price movements, and inflation expectations. Exchange rate changes and productivity also affect ostovoiman, especially in open economies or for imported goods.

Implications: Changes in ostovoiman influence consumer spending, saving, and welfare. Policymakers monitor ostovoiman to gauge living standards, while businesses and researchers use it to analyze wage negotiations and economic resilience.
