The US government cutting tax rate is an expansionary fiscal policy. When the exchange rates are fixed, an expansionary fiscal policy leads to an increase in the income. This would lead to a rise in the
Concept Introduction:
Current account: The current account is the entry of all the transactions of a country's net export, net income on investment, and net transfers as a part of the balance of payment.
Exchange rate: It is the rate at which one currency is exchanged for another currency.
Fixed exchange rate: It is the system of exchange where the exchange rate will be fixed and pre-determined by the central authority. It will be free from the demand and supply of currency in the exchange market.
Floating exchange rate: The floating exchange rate system is a system in which the exchange rate is determined at the equilibrium of the
Subpart (b):
To show the effect of each event on the current account balance and the exchange rate.
Subpart (b):

Explanation of Solution
When the fixed exchange rates prevail, the inflation level in US makes the products less attractive and expensive. This will lead to an increase in the imports and decrease in the exports resulting in a decrease in the current account balance. When the exchange rate floats, inflation would lead to depreciation in the dollar and the current account remains unaffected.

Depreciation of currency: It is the process of decreasing the value of a home currency with regard to another foreign currency in the currency exchange market.
Fixed exchange rate: It is the system of exchange where the exchange rate will be fixed and pre-determined by the central authority. It will be free from the demand and supply of currency in the exchange market.
Floating exchange rate: The floating exchange rate system is a system in which the exchange rate is determined at the equilibrium of the supply and demand for the currency. It will thus change the exchange rate according to the changes in the demand and supply.

Appreciation of currency: It is the process of increasing the value of a home currency with regard to another foreign currency in the currency exchange market.

Subpart (d):
To show the effect of each event on the current account balance and the exchange rate.
Subpart (d):

Explanation of Solution
When the consumers favor the domestically produced goods, the demand for imports decreases and this lead to a decrease in the demand for foreign currency. When the exchange rate is fixed, this would lead to an increase in the current account balance and when the exchange rate floats, this would lead to an appreciation of dollar. However, the impact on current account balance remains uncertain.

- Problem 2. If the consumer preference can be represented by a CES function with δ = 0.5, i.e. u(x, y) = x0.5 + y0.5. Let the prices and income be (px, py, w). 1. Set up the Lagrangian expression.2. Take the first-order conditions.3. Substitute into budget constraint to derive the optimal consumption bundles.arrow_forward1. A town relies on four different sources for its non-drinking water needs: dam water, reclaimed water, rain water, and desalinated water. The different sources carry different risks and costs. For instance, desalinated water is fully reliable due to abundant sea water, but it is more expensive than other options. Reclaimed water also has relatively lower risk than rain or dam water since a certain amount can be obtained, even during the dry. season, by the treatment of daily generated waste water. Using any of the four options requires an investment in that resource. The return on a particular water source is defined as the amount of water generated by the source per dollar of investment in it. The expected returns and standard deviations of those returns for the four water sources are described in the following table: Water resource Expected return St. Deviation Dam water 2.7481 0.2732 Reclaimed water 1.6005 0.0330 Rain water 0.5477 0.2865 Desalinated water 0.3277 0.0000 Higher…arrow_forward1. Imagine a society that produces military goods and consumer goods, which we'll call "guns" and "butter." a. Draw a production possibilities frontier for guns and butter. Using the concept of opportunity cost, explain why it most likely has a bowed-out shape. b. Show a point that is impossible for the economy to achieve. Show a point that is feasible but inefficient. c. Imagine that the society has two political parties, called the Hawks (who want a strong military) and the Doves (who want a smaller military). Show a point on your production possibilities frontier that the Hawks might choose and a point the Doves might choose. d. Imagine that an aggressive neighboring country reduces the size of its military. As a result, both the Hawks and the Doves reduce their desired production of guns by the same amount. Which party would get the bigger "peace dividend," measured by the increase in butter production? Explain.arrow_forward
