# Price level and interest rates relationship with dollar

As the price level rises the purchasing power of your money ill decline, Therefore, people will demand more money, then interest rate will increase and both the price of domestic goods increases in relation to the price of foreign goods, net A decline in the foreign exchange rate of the dollar; Increased security about. Jan 11, Next consider the effects of a price level increase in the money market. Inflation is calculated as the percentage increase in a country's price. The exchange rate has an important relationship to the price level because it the exchange rate (price of the U.S. dollar in terms of the Canadian dollar) times the inflation abroad, so that P rises relative to P*, the exchange rate Π ( domestic.

We will be four Lessons further along in the sequence before we look again at exchange rates, and a full understanding of how they are determined and their relationship to domestic economic policy will only emerge with completion of the entire sequence of Lessons. Nevertheless, before concluding this present Lesson we need to discuss further the law of one price and the relationship between the domestic and foreign price levels.

In order to write down Equation 2 we had to assume that all goods are produced everywhere and can be freely bought and sold across international boundaries without the impediment of transport costs, tariffs, taxes, or subsidies, so that Equation 1, the law of one price, holds for every good. Then we also assumed that each good represents the same fraction of aggregate output in each country so that countries' price indexes which are assumed to be output-weighted averages of the prices of goods produced are the same when the currencies exchange for each other on a one-for-one basis.

Of course, none of these assumptions are true, so how does the analysis change when they are false?

Transport costs, taxes, tariffs and subsidies are not a problem because we can think of prices as being net of these distortions.

But many goods are not traded internationally. The classic example is haircutsone can obtain a haircut for, perhaps, 50 cents in India but the costs of flying there to obtain it are prohibitive. Since people cannot migrate freely between countries, the labour share of production represents a non-traded component of every good.

This is why the price of a McDonalds hamburger, when measured in U.

### The Exchange Rate and the Price Level

Sides of beef and wheat flour can be purchased at roughly the same real price everywhere, but the labour used to make the patties, bake the bread, and provide the transport, cooking and clerical services is cheaper some places than others. Buildings, too, are built with local labour.

For these reasons a unit of aggregate output will not have the same price in all countries when measured in a single currency. The ratio of a country's price level to the price level in the rest of the world when all prices are converted into the same currency is called the country's real exchange rate.

It is the relative price of domestic output in terms of foreign output and can be written as 4. It is obvious that each country's real exchange rate will depend on which goods it produces not every good is produced in all countrieshow highly those goods are valued in world markets and on how high the productivity of domestic labour in producing domestic aggregate output is relative to the productivity of foreign labour in producing rest-of-world aggregate output.

There are some assumptions to be held to derive vertical long-run aggregate supply curve: That is the price level has not effect on real GDP. If the price level for real output real GDP increases, there will proportional increases in input prices.

Therefore, investors have no incentive to increase output. As a result, aggregate demand has no effect on long-run aggregate supply curve. Actually, imagine the production possibilities curve in chapter 2, the vertical aggregate supply curve is the mirror of that.

If you relax those assumptions above, then long-run aggregate supply curve can shift out or inward. The difference between short run aggregate supply curve and long-run aggregate supply curve is that short-run aggregate supply curve slopes upward because we assume that the costs of production wages do not change to offset changes in prices.

However, in the long run, because the costs of production adjust completely to changes in prices, therefore, neither profit nor output will increase. Why output can be expanded production in the short run is that firms can use labor and capital more intensively and the economy is producing below potential output full capacity is not reached.

However when capacity is reached then the curve will become vertical. Short run aggregate supply curve can shift to the left because of the input price increase the price of energy in the early s and 80s.

Factors that can shift aggregate supply outward Discoveries of new raw materials Labor supply increase A decrease in tax rates A decrease in input costs A decrease in international trade barriers The vice verse is true for those factors that shift aggregate supply curve inward.

A decrease in aggregate demand while aggregate supply holding constant will lead a short run equilibrium output. Trade deficits and surpluses also matter, as do stock-market and property valuations, the cyclical outlook for corporate profits, and positive or negative surprises for economic growth and inflation.

Finally, the widely assumed correlation between monetary policy and currency values does not stand up to empirical examination. But in other cases the opposite happens, for example when the euro and the pound both strengthened after their central banks began quantitative easing. For the US, the evidence has been very mixed. Over the next two-to-three years, the dollar index remained consistently below its level on the day of the first rate hike.

Just because the dollar weakened twice during the last two periods of Fed tightening does not prove that the same thing will happen again. But it does mean that a rise in the dollar is not automatic or inevitable if the Fed raises interest rates next month.
