Balassa-Samuelson Effect

What Is the Balassa-Samuelson Effect?

The Balassa-Samuelson effect states that productivity differences between the production of tradable goods in various countries 1) make sense of large noticed differences in wages and in the price of services and between purchasing power parity and currency exchange rates, and 2) it means that the currencies of countries with higher productivity will seem, by all accounts, to be undervalued in terms of exchange rates; this gap will increase with higher incomes.

The Balassa-Samuelson effect recommends that an increase in wages in the tradable goods sector of an emerging economy will likewise lead to higher wages in the non-tradable (service) sector of the economy. The going with increase in prices makes inflation rates higher in more quickly developing economies than it is in slow-developing, developed economies.

Grasping the Balassa-Samuelson Effect

The Balassa-Samuelson effect was proposed by business analysts Bela Balassa and Paul Samuelson in 1964. It recognizes productivity differences as the factor that leads to systematic deviations in prices and wages among countries, and between national incomes communicated utilizing exchange rates and purchasing power parity (PPP). These differences had been recently reported by empirical data accumulated by scientists at the University of Pennsylvania and are promptly noticeable by voyagers between various countries.

As per the Balassa-Samuelson effect, this is due to productivity growth differentials between the tradable and non-tradable sectors in various countries. High-income countries are all the more innovatively advanced, and hence more useful, than low-income countries, and the advantage of high-income countries is greater for the tradable goods than for the non-tradable goods. Concurring the law of one price, the prices of tradable goods ought to be equivalent across countries, however not really for non-tradable goods. Higher productivity in tradable goods will mean higher real wages for workers in that sector, which will lead to higher relative price (and wages) in neighborhood non-tradable goods that those workers purchase. Hence, the long-run productivity difference among high-and low-income countries leads to trend deviations between exchange rates and PPP. This likewise means that countries with lower per capita income will have lower domestic prices for services and lower price levels.

The Balassa-Samuelson effect proposes that the optimal inflation rate for creating economies is higher than it is for developed countries. Creating economies develop by turning out to be more useful and utilizing land, labor, and capital all the more proficiently. This outcomes in wage growth in both the tradable great and non-tradable great parts of an economy. Individuals consume more goods and services as their wages increase, which thusly pushes up prices. This infers that an emerging economy that is developing by raising its productivity will experience rising price levels. In developed countries, where productivity is now high and not rising as fast, inflation rates ought to be lower.


  • It additionally makes sense of why utilizing exchange rates as opposed to purchasing power parity to compare prices and incomes across countries will give various outcomes.
  • It suggests that the optimal rate of inflation will be higher for emerging nations as they develop and raise their productivity.
  • The Balassa-Samuelson makes sense of differences in prices and incomes across countries because of differences in productivity.
