Exchange Rate Pass Through

Definition: What is Exchange Rate Pass Through?

In macroeconomics and international trade, Exchange Rate Pass Through (ERPT) refers to the degree to which changes in exchange rates affect the prices of goods and services. This can be either import prices or export prices, depending on the context. Understanding the ERPT is crucial for policy makers as it impacts both domestic and international financial stability.

• High ERPT means that a large portion of currency fluctuations are passed on to the prices of goods and services.
• Low ERPT indicates that only a small part of currency changes affect import and export prices.

Exchange Rate Pass Through Formula and its Calculation

The ERPT into import prices can be estimated using the formula: \[ ERPT = \beta \] where \( \beta \) is the coefficient of the exchange rate variable in a regression of the log import price on the log exchange rate and other control variables. Following is a simplified example of a calculation table: Remember, the values obtained using this formula are then used to analyse how changes in exchange rate affect prices of goods and services.

Practical Example of Exchange Rate Pass Through in International Economics

Let's consider an example: This example illustrates how ERPT can have profound impacts on international trade. It affects the competitiveness of a country's exports and can influence decision-making among businesses.

Currency Choice and Its Effect on Exchange Rate Pass Through

Currency choice alludes to the determination of the unit of account for international trade or a specific denomination of a financial transaction. The currency choice can either be the importer's currency, the exporter's currency or a separate, typically more stable, vehicle currency like the US dollar or the Euro. Currency choice can significantly affect the exchange rate pass through, primarily by determining who bears the exchange rate risk. It could influence prices and ultimately, the competitiveness of goods in the global market.

Explanation of Currency Choice in Macroeconomics

Currency choice in macroeconomics describes the selection of a specific currency for denomination of international trade transactions and financial contracts. In simpler terms, currency choice answers the question - 'In what currency should international trade or financial transactions take place?' The factors that might affect the currency choice include relative volatility of currencies, bilateral trade costs, market commonalities and monetary policies. In world trade, a majority of transactions are dominated in very few currencies, notably the US dollar, Euro and Yen. This is despite the fact that these currencies are native to countries which account for a relatively small fraction of the global trade.

Impact of Currency Choice on Exchange Rate Pass Through

The currency choice can affect the extent of exchange rate pass through considerably. When the exporter's currency is used, the importer bears the risk and cost of exchange rate fluctuations and relatively high ERPT can be expected. In contrast, when the importer's currency is used, the exporter absorbs the exchange rate risk, contributing to relatively lower ERPT. The ERPT tends to be incomplete when a vehicle currency is used. It is less than one as neither party bears the full extent of exchange rate risk.

• A high ERPT implies that currency fluctuation costs are largely passed on to the customer in the form of price changes.
• A low ERPT indicates that producers marginally adjust their prices according to exchange rate changes.

Discussing impact points in detail: Currencies with relatively higher stability and lower inflation tend to be chosen more as the currency of trade invoicing, thereby influencing ERPT dynamics.

Case Study: Currency Choice and Exchange Rate Pass Through Scenario

Let's examine a case illustrating how currency choice affects ERPT: This practical example shows how currency choice may significantly impact the pass-through of exchange rate changes to import or export prices. Hence, understanding these dynamics offers a wealth of insight for businesses and policy makers alike in navigating international economics.

Exchange Rate Pass Through and Its Influence on Inflation

Exchange Rate Pass-through (ERPT) and inflation are tightly interconnected concepts in economics, particularly in open economies that engage in large volumes of international trade. ERPT determines how much of the exchange rate fluctuations are passed on to import and export prices, which could subsequently alter the general price level, thereby affecting inflation. Understanding this relationship is crucial for policy makers trying to achieve price stability and control inflation in their respective economies.

Connection Between Exchange Rate Pass Through and Inflation

The connection between ERPT and inflation is intertwined, closely affecting each other. Specifically, changes in exchange rates can influence domestic prices, which in turn may impact the overall inflation rate in the economy. The chain of effects typically starts with fluctuations in the exchange rate. These fluctuations can occur due to various factors such as changes in relative inflation rates, interest rates, economic growth rates, political stability, and even speculation. Once exchange rates start changing, they affect the costs of imports and the value of exports. If the domestic currency devalues or depreciates, import prices likely increase as it now requires more of the domestic currency to purchase the same quantity of goods. This rise in import prices can subsequently lead to an increase in domestic prices if the ERPT is high, as producers might pass on the higher import costs to consumers. On the other hand, if the domestic currency appreciates, import prices tend to decrease because fewer units of domestic currency are required to purchase the same amount of foreign goods. This decline in import prices could potentially lead to a decrease in domestic prices, thereby putting a downward pressure on inflation, given that the ERPT is sufficiently high enough for these changes to fully reflect on domestic prices. Therefore, the ERPT is a key determinant of the extent to which exchange rate fluctuations translate into inflation. A complete pass-through, where ERPT is equal to one, means that all exchange rate changes are fully reflected in domestic prices, thereby having a substantial effect on inflation. It's important to remember that ERPT is typically less than one, meaning that not all cost changes resulting from exchange rate fluctuations are passed into prices. This could be due to several factors such as:

• Market Power and Pricing-to-market: Firms might absorb part of the cost changes to maintain their market share in foreign markets.
• Menu Costs: Firms might avoid changing prices frequently to avoid costs associated with price adjustments.
• Nominal Price Stickiness: Prices might not respond quickly to changes in costs due to factors like long-term contracts and price-setting habits.

How does Exchange Rate Pass Through Influence Inflation Rates

The degree of ERPT profoundly influences inflation rates. A high ERPT suggests that a larger proportion of exchange rate changes ultimately reflects in domestic prices and affects inflation. For economies that rely heavily on imported goods and services, a high pass-through can significantly influence inflation, as changes in import prices would cascade into the general price level. When a domestic currency depreciates, a high ERPT translates this into a higher cost for imported goods, which tends to increase inflation. Conversely, a low ERPT indicates that only a portion of the currency fluctuations are reflected in import prices. In this case, the impact on inflation would be comparatively lower. With a low pass-through, the effects of exchange rate changes on inflation are mitigated, making inflation less sensitive to exchange rate fluctuations. A firm may choose to absorb a fraction of the cost increases associated with exchange rate changes, especially if it operates in a competitive market where altering prices frequently can lead to loss of market share.

Real-life Illustration: Exchange Rate Pass Through Causing Inflation

Consider a real-life scenario of ERPT leading to inflation: This example illustrates how ERPT can potentially trigger inflation owing to the pass-through of exchange rate changes to domestic prices. Therefore, it is important for both businesses and policy makers to understand and consider the degree of ERPT in decision-making concerning import pricing, monetary policy and inflation management.

Exchange Rate Pass Through and Its Effect on Import Prices

The principle of Exchange Rate Pass Through (ERPT) plays a critical role in determining import prices. It revolves around the degree to which changes in exchange rates get translated into the prices of imported goods. A good understanding of ERPT is pivotal in the realms of trade, monetary policy, and economic projections.

The Role of Exchange Rate Pass Through in Determining Import Prices

ERPT, by definition, is the degree to which changes in exchange rates influence the prices of imported goods. To simplify, should a currency depreciate by 10%, and if the idea of full pass-through held, import prices would surge by 10%. Here, the ERPT is 100% because all of the exchange rate variation gets passed on to the import costs. Nevertheless, what is observed in reality often leans towards incomplete pass-through, where the import prices do not reflect the entirety of the exchange rate fluctuations. The ERPT's extent varies based on a myriad of factors. They include:

• Market Competition: In a highly competitive market, firms often find themselves unable to pass the entirety of their cost changes, driven by exchange rate differences, on to consumers. This results in a lower ERPT.
• Product Differentiation: When it comes to highly differentiated products, consumers have fewer substitutes. Firms may successfully pass over more of their cost changes resulting from exchange rate fluctuations, thereby ushering in a greater ERPT.
• Pricing to Market: When exporters price discriminately across markets in line with local market conditions, they subtend a lower ERPT.

How Exchange Rate Pass Through Impacts Import Prices in International Economics

The theory of ERPT holds profound implications for global economics, especially in pricing strategies and competitiveness. When a domestic currency depreciates, the costs of imported goods rise. A high ERPT could see this cost hike passed on to consumers, implying steeper import prices. It potentially disrupts the competitiveness, demand, and consumption of these goods, impacting trade balances and potentially leading towards inflation. However, when the ERPT is low, importers or foreign exporters might absorb the additional costs incurred due to the weaker domestic currency. This implies the import prices rise only marginally despite significant exchange rate fluctuations. The real effects of exchange rate changes are then cushioned and are much less noticeable in the trade and macroeconomic aggregates.

Case Examples: Exchange Rate Pass Through into Import Prices

A practical scenario offers a more tangible comprehension of how ERPT impacts import prices. In a second example, think of a US electronics firm that imports its components from Japan. Should the Yen depreciate against the US Dollar: As these cases exemplify, ERPT's influence on import prices has sizable implications for businesses, consumers, and economies at large. Therefore, getting to grips with this concept proffers insights useful enough to better navigate the global economic landscape.

Exploring the Effects of Exchange Rate Pass Through in Macroeconomics

The exchange rate pass through (ERPT) is an essential part of macroeconomics, especially in terms of international trade, price stability and inflation. ERPT, to put it simply, is the responsiveness of import prices to changes in the exchange rate.

Dive into the Effects of Exchange Rate Pass Through in Global Economies

The exchange rate pass through significantly impacts global economies through its effects on import prices and inflation. This mechanism is of particular importance in open economies with high import content in the consumer basket.

• In the case of an appreciation of the local currency, import prices tend to decrease. Now suppose a high ERPT is in effect, the decrease in import prices can get passed on to domestic prices, consequently putting downward pressure on inflation.
• Conversely, a depreciation of the local currency generally leads to an increase in import prices. If the ERPT is high, this can result in a rise in domestic prices, subsequently exerting an upward pressure on inflation.

ERPT can also influence export competitiveness. With a depreciating local currency and high ERPT, domestically produced goods and services become cheaper on the international market, potentially raising the competitiveness of domestic firms.

Quantifying the Effects of Exchange Rate Pass Through Using Examples

An illustrative example is useful in quantifying the effects of ERPT: ERPT can be experimentally measured using econometric methods. The simplest setup is a linear regression where the log change in import prices is regressed on the log change in the exchange rate and possibly other control variables. The coefficient of exchange rate changes thus obtained gives the ERPT. \[ ERPT = \beta \] where \(\beta\) is the coefficient of the exchange rate variable in the regression.

Analysis: Varied Exchange Rate Pass Through Effects Across Countries

ERPT effects can widely vary across different countries. This variation might reflect the differences in the economies' structural features, including the level of development, openness, and the extent of dollarization or euroization. For example, research has found evidence of high ERPT in developing economies. This is often attributed to structural characteristics such as higher import content, less credible monetary policy framework, and higher persistence of exchange rate shocks. In contrast, industrialized economies often exhibit lower ERPT due to well-established monetary policy practices that bring credibility to their inflation objectives, preventing full pass-through of exchange rate changes. The degree of ERPT can have profound implications for policy making. Particularly, it has important repercussions for the choice of exchange rate regime and the conduct of monetary policy. A country with high ERPT might be more prone to inflationary pressures due to depreciations of the local currency. On policy grounds, this might require increased diligence from policy makers in monitoring and responding to exchange rate movements for inflation control. On the other hand, in a country with low ERPT, monetary policy can perhaps afford to be more accommodative to exchange rate fluctuations, focusing instead on other domestic variables as anchors for monetary policy decisions. Understanding the nature and degree of ERPT is therefore crucial for both policy makers and businesses operating in the international market, forming the basis for more effective decision-making both in economic management and business strategy creation.
