GDP Purchasing Power Parity (PPP)

Question 1

What does Purchasing Power Parity (PPP) fundamentally measure?

Accepted Answer

The relative value of currencies based on the cost of a comparable basket of goods

Answer

PPP measures how much a common basket of goods and services costs in different countries, allowing economists to compare the relative purchasing power of currencies.

Question 2

The informal 'Big Mac Index,' used as a practical illustration of PPP, was created by which organization?

Accepted Answer

The Economist magazine

Answer

The Big Mac Index was introduced by The Economist magazine in 1986 as a lighthearted way to assess whether currencies are at their correct PPP-implied level.

Question 3

According to PPP theory, in the long run, exchange rates should adjust so that:

Accepted Answer

Identical goods and services cost the same price across countries in a common currency

Answer

PPP theory holds that arbitrage will drive prices toward equality, so identical goods should cost the same across countries once expressed in a common currency.

Question 4

When GDP figures are adjusted for PPP, the primary purpose is to:

Accepted Answer

Adjust for differences in price levels so that cross-country comparisons reflect actual purchasing power

Answer

PPP adjustment controls for differences in price levels between countries so that GDP comparisons reflect what money can actually buy rather than just its nominal exchange rate value.

Question 5

The 'Law of One Price,' which underpins PPP theory, states that:

Accepted Answer

In competitive, open markets, identical goods will sell for the same price when expressed in a common currency

Answer

The Law of One Price holds that competitive arbitrage will equalize prices for identical goods across markets when transportation costs and trade barriers are absent.
