International Finance: Theory and Policy

Overview

International Finance: Theory and Policy develops open-economy macroeconomics through national accounts, foreign exchange, parity relationships, money, output, and exchange-rate regimes. The Open Textbook Library credits Steve Suranovic. Its linked archival PDF is titled Policy and Theory of International Finance, version 1.0, and contains thirteen chapters across 523 pages. This guide makes that title difference explicit while following the complete archive. Models are studied as conditional explanations: their results depend on assumptions about prices, expectations, capital movements, policy, and the exchange-rate system. Historical figures and policy examples are not presented as current market information or investment recommendations.

How to study this book

Fix the exchange-rate quotation convention before any calculation and write units beside every rate. Keep accounting identities separate from behavioral equations and equilibrium conditions. For each model, list assumptions, endogenous variables, exogenous changes, and the adjustment story. Draw diagrams before and after a shock using the same conventions. Compare floating and fixed regimes by explaining what the central bank must do and which variables adjust. Treat numerical examples as demonstrations of mechanisms. A model’s prediction should always be stated with the conditions under which it follows.

Chapter and section study guide

Chapter 1 — Introductory Finance Issues

International finance connects output, prices, employment, exchange rates, trade balances, investment positions, and international institutions. The chapter introduces recurring macroeconomic indicators and historical patterns used later in the book. A country’s position cannot be summarized by one figure, and a flow such as a trade balance differs from a stock such as an investment position. Institutions including the IMF and World Bank have distinct roles. Use the opening material to establish definitions and questions, while treating its numerical comparisons as dated observations.

Study application: Construct an indicator table that separates stocks from flows and identifies the date and unit needed to interpret each measure.

Chapter 2 — National Income and Balance of Payments

National-income accounting and balance-of-payments records organize international transactions through consistent definitions. Exports, imports, income flows, saving, investment, and financial transactions connect through identities. These identities constrain possible combinations but do not by themselves establish the causal direction of adjustment. The chapter also distinguishes an international investment position from annual transactions. Pay attention to signs and recording conventions, especially when comparing sources. An apparent imbalance in one account has a counterpart elsewhere; explaining why it occurs requires additional behavioral and institutional analysis.

Study application: Record a small set of international transactions and distinguish the accounting relationship from a causal explanation of the resulting balances.

Chapter 3 — The Whole Truth about Trade Imbalances

Trade deficits and surpluses have different implications depending on circumstances, financing, timing, and the uses of resources. The chapter challenges automatic judgments that a deficit is always a loss or a surplus always a gain. Intertemporal trade and investment help explain why countries exchange present and future resources. Distributional effects and adjustment risks still matter, so rejecting a simplistic judgment does not imply every imbalance is benign. Evaluate the mechanism and context rather than the sign alone. Separate national accounting from claims about employment or welfare.

Study application: Compare two hypothetical deficits financed for different purposes and explain why their implications need not be identical.

Chapter 4 — Foreign Exchange Markets and Returns

Exchange-rate quotations describe the price of one currency in another, and changing the quotation changes the interpretation of appreciation. International investment returns depend on the asset return and currency conversion, including the later exchange rate. The chapter connects market participants and objectives with a common basis for comparing returns. A higher foreign interest rate does not alone establish a higher home-currency return. State which currency the investor ultimately values and separate known rates from uncertain future movements. Precision about units prevents many apparent contradictions.

Study application: Calculate a home-currency return under two exchange-rate outcomes and explain why the interest-rate comparison alone was incomplete.

Chapter 5 — Interest Rate Parity

Interest rate parity relates returns across currencies under specified assumptions about assets, expectations, and market adjustment. The chapter uses return diagrams to explain exchange-rate equilibrium and comparative statics. A change in a domestic rate, foreign rate, or expected future exchange rate shifts incentives and the equilibrium relationship. Distinguish a model condition from a risk-free trading opportunity in actual markets. Expectations and risk assumptions are central, not optional details. Explain how an initial return difference creates pressure for adjustment rather than simply quoting a parity formula.

Study application: Trace an increase in the domestic interest rate through the source’s return diagram, holding the stated other conditions constant.

Chapter 6 — Purchasing Power Parity

Purchasing power parity connects exchange rates with relative price levels through goods-market reasoning. Absolute and relative forms ask different questions and require clear definitions. Transport costs, nontraded goods, barriers, basket composition, and adjustment frictions complicate direct application. The chapter develops both the logic and limitations of the relationship. A long-run organizing idea should not be confused with a precise short-run exchange-rate forecast. Compare what the model predicts with the conditions necessary for prices and trade to generate that result.

Study application: Explain a possible deviation from purchasing power parity using a nontraded service or a trade cost rather than treating it as a numerical anomaly.

Chapter 7 — Interest Rate Determination

Money supply, money demand, prices, and real economic activity interact in the source’s interest-rate model. The equilibrium rate balances the relevant demand and supply under specified conditions. Changes in policy or economic activity alter that relationship and connect monetary conditions with foreign-exchange outcomes. Distinguish nominal money from real balances and a movement along a relationship from a shift. The chapter prepares a model input used in later open-economy analysis. Explain the adjustment mechanism and the assumed time horizon before combining it with another diagram.

Study application: Show how a change in money supply affects the model’s equilibrium interest rate and list the quantities held fixed.

Chapter 8 — National Output Determination

Output determination links expenditure decisions with production under the model’s short-run assumptions. Consumption, investment, government demand, and external demand influence planned spending, while imports connect domestic expenditure with foreign production. Equilibrium is a condition to be explained through an adjustment process rather than simply a crossing of lines. The chapter supplies the goods-market foundation for the AA-DD framework. Keep an accounting identity separate from the behavioral relationships used to determine output. Specify which variables are fixed before interpreting a multiplier or a policy effect.

Study application: Trace a change in one expenditure component through planned spending, imports, and equilibrium output under the source assumptions.

Chapter 9 — The AA-DD Model

AA-DD combines asset-market and goods-market equilibrium to connect output and the exchange rate. Each curve represents a set of equilibrium combinations, and its slope or shift follows from the underlying mechanisms. The model’s usefulness depends on maintaining consistent assumptions about prices, expectations, monetary conditions, and expenditure. A shock can shift one or both relationships, so identify its direct effect before tracing feedback. The intersection is a joint condition, not proof that every actual economy adjusts instantaneously. Use the framework to make conditional comparisons.

Study application: Explain the economic reasoning behind each curve and analyze one shock without changing the quotation convention midway.

Chapter 10 — Policy with Floating Exchange Rates

Under floating exchange rates, monetary and fiscal changes affect asset and goods markets while the exchange rate can adjust. The chapter uses AA-DD to compare mechanisms and distinguish temporary from persistent changes where relevant. A policy effect depends on expectations and the model’s assumptions, not just the label monetary or fiscal. Trace the initial shift, exchange-rate response, expenditure changes, and final equilibrium. The framework clarifies trade-offs and interactions but does not supply a universal prediction independent of context or a recommendation for current policy.

Study application: Compare a monetary expansion and a fiscal expansion under the same floating-rate assumptions, explaining each adjustment path.

Chapter 11 — Fixed Exchange Rates

A fixed exchange rate requires an institutional commitment and actions that maintain the stated rate. Central-bank intervention connects foreign-exchange transactions with domestic monetary conditions and reserve holdings. The chapter explains how a regime differs from simply observing a stable market price. Sustainability depends on circumstances and expectations, while adjustments can place pressure on reserves or domestic variables. Distinguish the announced parity from the mechanism supporting it. The chapter provides the operating logic needed to analyze policy effects under a fixed rather than floating rate.

Study application: Describe how intervention to defend a fixed rate affects the central bank’s balance sheet and the relevant monetary conditions.

Chapter 12 — Policy with Fixed Exchange Rates

Fixing the exchange rate changes the adjustment process and the scope for independent policy within the model. Monetary or fiscal actions may trigger intervention that reinforces or offsets an initial effect. The chapter compares these channels using the same AA-DD logic introduced earlier. Explain what the central bank must do to preserve the rate and how that response changes the final outcome. Results depend on the maintained assumptions and credibility of the regime. A clear comparison identifies the variable constrained by the regime and those left to adjust.

Study application: Reanalyze one policy shock from Chapter 10 under a fixed rate and explain why the adjustment differs.

Chapter 13 — Fixed versus Floating Exchange Rates

The final chapter compares regimes through stability, adjustment, policy autonomy, uncertainty, and institutional requirements. Neither arrangement can be judged solely by one favorable property. The appropriate comparison depends on shocks, economic relationships, credibility, and objectives. Distinguish theoretical advantages from the practical conditions needed to realize them. The chapter synthesizes the earlier models by showing how a regime changes both incentives and constraints. A defensible conclusion should state its assumptions, acknowledge trade-offs, and explain which evidence would lead to a different judgment.

Study application: Prepare a regime comparison for a hypothetical economy facing two different shocks, explicitly weighting objectives and institutional capacity.

Reflection and review

1. Which relationship in your analysis is an identity and which depends on behavioral assumptions?
2. How does the exchange-rate quotation affect the interpretation of your diagram?
3. What assumption would most weaken your policy comparison if it failed?
