Macroeconomics Answers

Suppose nominal wages never changed. What would be the significance of such a characteristic?

Give three reasons for the downward slope of the aggregate demand

curve.

4. How would an increase in the supply of labor affect the natural level of employment and potential output? How would it affect the real wage, the level of real GDP, and the price level in the short run? How would it affect long-run aggregate supply? What kind of gaps would be created

Recall that an exchange rate is the price of one currency in another. For example, it may take US $1.35 to buy 1 British Pound. Also recall the interest rates affect exchange rates. What do you predict will happen to the foreign exchange rate if interest rates in the United States increase more than in the UK? (In other words, which currency will become stronger?) How would such a change affect US exports to the UK? Would it be less expensive for an American tourist to take a vacation to London after the interest rate change? Be sure to clearly explain and justify your reasoning.

d. Using year 1 prices, what is real GDP per worker in year 1 and year 2? What is labour productivity growth between year 1 and year 2 for the whole economy? Now suppose that banking services in year 2 are not the same as banking services in year 1 because they include internet banking, which year 1 banking services didn’t include. The technology for internet banking was available in year 1 but the price of banking services with internet banking in year 1 was $13 and no one chose that package. However, in year 2 the price of banking services with internet banking was $12 and everyone chose to have that package in year 2 (that is, in year 2 no one chose to have the year 1 banking services package without internet banking).
