Understanding Purchasing Power Parity (PPP) Study Guide

Foundations of Purchasing Power Parity (PPP)

Purchasing Power Parity (PPP) is an economic measure used to compare the price of specific goods in different countries to assess currency purchasing power.

Answer: True

Explanation: Purchasing Power Parity (PPP) is indeed an economic measure employed to compare the prices of specific goods across different countries, thereby evaluating the comparative purchasing power of their respective currencies.

Return to Game

Purchasing Power Parity is based on the 'law of diminishing returns,' which suggests prices should equalize across locations.

Answer: False

Explanation: Purchasing Power Parity is fundamentally based on the 'law of one price,' not the 'law of diminishing returns.' The law of one price posits that identical goods should have the same price globally when trade barriers are absent.

Return to Game

The core idea of PPP is that consumers in every location should have the same purchasing power when the correct exchange rate is applied.

Answer: True

Explanation: The fundamental concept of Purchasing Power Parity (PPP) is that, theoretically, with the appropriate exchange rate, consumers in different locations should possess equivalent purchasing power, enabling them to acquire the same quantity of goods and services.

Return to Game

Relative PPP focuses on the absolute price levels of goods between countries at a single point in time.

Answer: False

Explanation: Relative PPP focuses on the *changes* in exchange rates and inflation differentials over time, whereas Absolute PPP posits that exchange rates should equalize the price ratios of goods between countries at a specific point in time.

Return to Game

The law of one price is the theoretical foundation for PPP, stating identical goods should have the same price globally without barriers.

Answer: True

Explanation: The law of one price serves as the foundational principle for PPP, asserting that identical goods should command the same price across different locations when free from trade barriers and transaction costs.

Return to Game

What is the fundamental principle underpinning the concept of Purchasing Power Parity (PPP)?

Answer: The law of one price.

Explanation: The fundamental principle underpinning Purchasing Power Parity is the 'law of one price,' which posits that identical goods should have the same price in different locations when trade barriers are absent.

Return to Game

What does the term 'purchasing power parity' imply about consumers?

Answer: Consumers in every location should possess the same purchasing power with the correct exchange rate.

Explanation: The term 'purchasing power parity' implies that, when using the correct exchange rate, consumers in all locations should have equivalent purchasing power, enabling them to buy the same basket of goods and services.

Return to Game

What is the primary difference between Relative PPP and Absolute PPP?

Answer: Absolute PPP posits exchange rates equal price ratios, while Relative PPP focuses on changes in exchange rates matching inflation differentials.

Explanation: Absolute PPP suggests that exchange rates should equal the ratio of price levels between countries for a basket of goods, while Relative PPP focuses on the relationship between changes in exchange rates and inflation differentials over time.
