Students have asked these similar questions
exports and the IS curve: Consider the way in which net exports dependon the real exchange rate. Does the dependence of net exports on the realexchange rate make the IS curve steeper or fatter?
Consider the following equation:
NX(ɛ) = S - I(r*)
This equation is used to draw the diagram illustrating the foreign exchange market, where there is
a negative relationship between NX and ɛ; and S, - I(r*) is perfectly inelastic.
Here NX is net exports, ɛ is the exchange rate, S represents the level of savings in the economy, I
represent the level of investment in the economy, and r is the interest rate.
a. Use a carefully labeled diagram to illustrate the effect of a contractionary fiscal policy at
home on savings, interest rate, net capital outflow and the exchange rate
b. Use a carefully labeled diagram to illustrate the effect of a contractionary fiscal policy
abroad on savings, interest rate, net capital outflow and the exchange rate
What does this graph show and what is the relationship between real exchange rate and net exports?

Suppose that incomes decrease in Mexico, causing Mexican consumers to purchase fewer U.S.-made goods and services. How does this affect the peso-dollar exchange rate? Drag the appropriate curve(s) on the following graph to illustrate how this change affects the market for dollars. Tool tip: Click and drag one or both of the curves. Curves will snap into position, so if you try to move the curve and it snaps back to its original position, just try again and drag it a little farther.

For example, how much does it cost in Canadian dollars to buy one US dollar? There are various economic theories to predict exchange rates. The simplest theory is known as the Law of One Price or also known as Absolute Purchasing Power Parity (PPP). Use absolute PPP and the price of a Big Mac in different countries to complete the table below and to predict whether the local currency is over or undervalued compared to the US dollar.

- It is possible to assert that the exchange rate is endogenous in the equation system nx = c1 + c2 y + c2 ex + u, where nx is net exports, y is gross domestic product, and ex is real exchange rate. Defend this assertion.arrow_forwardIn the foreign exchange market, the supply curve for the dollar is upward sloping. That is, when the exchange rate (foreign currency per dollar) increases, the quantity of dollars supplied increases. Assuming actors have not yet had time to change their expectations about the future exchange rate, when the exchange rate increases, why is the supply curve of dollars in the foreign exchange market upward sloping? Foreign goods and services are less expensive to import. U.S. firms profit more by selling their goods and services domestically rather than selling to foreigners. The expected profitability of purchasing a dollar today to sell in the future rises. U.S. goods are less expensive for foreigners to purchase.arrow_forwardAccording to a survey ("Big MacCurrencies," The Economist, April 17th 1993), in 1993, the average price of a Big Mac in the U.S. was $2.28.

Based on the discussion of these two ideas in this chapter which of the below statements would you consider to be INCORRECT? A) The rate at which one currency can be exchanged for another is the exchange rate. B) Exchage rates include only the values of internationally tradable items, while the PPP includes both internationally tradable items as well as those which are not internationally tradable items but are used by people in different countries. C) If $25 can purchase a bundle of goods in the U.S. and if a comparable bundle of goods wil cost 750 rubles in Russia, then the PPP between the U.S. dollar and the Russian ruble would be $25=750 Russian rubles.
