International Business (Intl Biz) 101: International Finance Determinants of Exchange Rates Interest Rate Parity Purchasing Power Parity PPP Absolute and Relative Inflation Differentials Balance of Payments Political Stability Expectations C

What This Is

Determinants of exchange rates refer to the various factors that influence the value of one country's currency relative to another. Understanding these determinants is crucial for international business as it affects the competitiveness of exports, imports, and foreign direct investment (FDI). For instance, if the US dollar appreciates against the euro, it becomes more expensive for US companies to import goods from Europe, while European companies face a lower demand for their exports in the US.

Key Theories & Frameworks

• Interest Rate Parity (IRP): IRP states that the difference in interest rates between two countries should be equal to the expected difference in exchange rates. This implies that investors can earn the same return by investing in either country. Practical implication: Companies should consider interest rates when making investment decisions.
• Purchasing Power Parity (PPP) - Absolute: PPP-absolute states that the exchange rate between two countries should be equal to the ratio of their price levels. This means that the same basket of goods should cost the same in both countries. Practical implication: Companies should adjust their prices for exports and imports according to the PPP rate.
• Purchasing Power Parity (PPP) - Relative: PPP-relative states that the exchange rate between two countries should be equal to the ratio of their price levels relative to a third country. Practical implication: Companies should consider the relative price levels when making investment decisions.
• Inflation Differentials: Inflation differentials refer to the differences in inflation rates between two countries. Higher inflation in one country can lead to a depreciation of its currency. Practical implication: Companies should consider inflation rates when making investment decisions.
• Balance of Payments (BOP): BOP refers to the record of a country's international transactions over a specific period. A country's BOP can affect its exchange rate. Practical implication: Companies should consider a country's BOP when making investment decisions.
• Political Stability: Political stability can affect a country's exchange rate. A stable government can lead to a stable currency. Practical implication: Companies should consider a country's political stability when making investment decisions.
• Expectations: Expectations refer to the market's forecast of future exchange rates. If investors expect a currency to appreciate, they will buy it now, leading to an appreciation. Practical implication: Companies should consider market expectations when making investment decisions.
• Central Bank Intervention: Central banks can intervene in the foreign exchange market to influence the exchange rate. Practical implication: Companies should consider central bank intervention when making investment decisions.
• International Fisher Effect (IFE): IFE states that the difference in interest rates between two countries should be equal to the expected difference in exchange rates, adjusted for inflation. Practical implication: Companies should consider IFE when making investment decisions.

Step-by-Step Application

1. Analyze the exchange rate determinants: Identify the key factors affecting the exchange rate, such as interest rates, inflation differentials, and expectations.
2. Assess the impact on trade: Determine how the exchange rate will affect trade, including imports and exports.
3. Consider investment decisions: Evaluate the impact of the exchange rate on investment decisions, including FDI and portfolio investments.
4. Monitor central bank intervention: Keep track of central bank intervention in the foreign exchange market.
5. Adjust prices and costs: Adjust prices and costs for exports and imports according to the PPP rate.
6. Consider hedging strategies: Evaluate the need for hedging strategies to mitigate exchange rate risk.

Common Mistakes

• Mistake: Assuming that PPP-absolute is the same as PPP-relative.
• Correction: PPP-absolute refers to the ratio of price levels, while PPP-relative refers to the ratio of price levels relative to a third country.
• Mistake: Confusing FDI with foreign portfolio investment.
• Correction: FDI involves the establishment of a subsidiary or joint venture, while foreign portfolio investment involves the purchase of stocks or bonds.
• Mistake: Misapplying cultural dimensions as stereotypes.
• Correction: Cultural dimensions should be used to understand cultural differences, not to make assumptions about a country or company.

Exam / Case Interview Tips

• Be prepared to explain the key exchange rate determinants: Understand the theories and frameworks, and be able to apply them to case studies.
• Consider the impact on trade and investment: Evaluate the impact of the exchange rate on trade and investment decisions.
• Monitor central bank intervention: Keep track of central bank intervention in the foreign exchange market.
• Be aware of cultural differences: Understand cultural differences and how they can affect business decisions.

Quick Practice Scenario

A Brazilian firm wants to enter the German market. What entry mode is lowest risk?

Answer: Exporting through a third-party distributor is the lowest risk entry mode.

Explanation: Exporting through a third-party distributor allows the Brazilian firm to test the market without committing to a full-scale investment.

Last-Minute Cram Sheet

• ⚠️ "Absolute advantage" is different from "comparative advantage" – absolute means lower cost of production; comparative means lower opportunity cost, which always exists even if one country is better at everything.
• The International Fisher Effect (IFE) states that the difference in interest rates between two countries should be equal to the expected difference in exchange rates, adjusted for inflation.
• Purchasing Power Parity (PPP) refers to the ratio of price levels between two countries.
• Balance of Payments (BOP) refers to the record of a country's international transactions over a specific period.
• Central bank intervention can influence the exchange rate.
• Expectations refer to the market's forecast of future exchange rates.
• Inflation differentials can affect the exchange rate.
• Interest Rate Parity (IRP) states that the difference in interest rates between two countries should be equal to the expected difference in exchange rates.
• Political stability can affect the exchange rate.
• PPP-absolute refers to the ratio of price levels, while PPP-relative refers to the ratio of price levels relative to a third country.
