2 Copyright © 2008 Pearson Addison-Wesley. All rights reserved. 13-2 Chapter 13 Topics A two-good model of a small open economy. The benefits from trade, and the macroeconomic effects of a change in the terms of trade. A two-period small open economy model: the current account. Production, investment, and the current account.

3 Copyright © 2008 Pearson Addison-Wesley. All rights reserved. 13-3 A two-good model of a small open economy Production possibilities frontier. Indifference curves of the representative consumer. Illustrate equilibrium when there is not trade, and when the SOE is a price-taker on world markets.

6 Copyright © 2008 Pearson Addison-Wesley. All rights reserved. 13-6 Equation 13.1 In equilibrium the consumer maximizes when his or her marginal rate of substitution equals the relative price of the two goods.

7 Copyright © 2008 Pearson Addison-Wesley. All rights reserved. 13-7 Equation 13.2 Optimal behavior by firms implies that the marginal rate of transformation is equal to the relative price of the two goods in equilibrium.

14 Copyright © 2008 Pearson Addison-Wesley. All rights reserved. 13-14 An Increase in the terms of trade Effects depend on which good is initially imported. Income and substitution effects are an important element in analyzing the implications of a change in the terms of trade.

17 Copyright © 2008 Pearson Addison-Wesley. All rights reserved. 13-17 A Two-Period Small Open Economy Model Two periods – current period and future period. Representative consumer with exogenous current-period and future-period incomes. The SOE is a price-taker on world credit markets – the real interest rate is exogenous. The current account surplus here is equal to savings in the SOE, as there is no investment.

24 Copyright © 2008 Pearson Addison-Wesley. All rights reserved. 13-24 A Small Open Economy Model with Production and Investment Works the same as the real intertemporal model, except the real interest rate is determined on world credit markets, and given to the SOE. Current account surplus always adjusts so that the aggregate supply and aggregate demand curves intersect at the world real interest rate.
