Document Summary

Macroeconomics is the study of the overall or aggregate performance of an economy. An economy"s total output of goods and services is measured by the real gross domestic product (gdp) Gdp can be broken into four major components: consumption (c, gross private domestic investment (i, government consumption and investment (g, net exports of goods and services (nx) An economy"s quantities of goods or labour can be measured using the aggregates of employment and unemployment. A model can be a group of equations or graphs or a set of conceptual ideas. An economic model deals with two kinds of variables: endogenous variables determined within the model, exogenous variables determined outside of the model. Assuming the market is perfectly competitive, each buyer and seller is too small to affect the market price: each individual is considered a price-taker. For long-run analysis, a market-clearing framework is used to assume there is always pressure for the market price to adjust towards the equilibrium price.

There are many economic models to explain the macro-economies function. Adam Smith started the classic economic thinking with his laissez-faire theory. The classical foundation for the role of money supply in an economy started in the mid-1700s. In classic macroeconomics, money is used for transactions. If there is more money or less money in circulation then it means that the prices are higher or lower. The classic model dominated microeconomics and macroeconomics of 1800 and 1900. In the classic macroeconomic model, the role of money is that it is used for transactions. The classic role of money can be understood through the quantity theory of money. The quantity theory of money states that if there are changes in the price level, then there will be corresponding changes in the money supply. The equation for the quantity theory of money is: M * V = P * Q

In this equation,

M = Nominal money supply

V = Velocity of money

P = Average price level

Q = Quantity of goods and services sold

The average price times quantity of goods and services sold represents the nominal GDP. The velocity of money is the number of times a currency is spent during a year.

Say's Law states that supply creates its own demand. It means that the income that is derived from producing some goods by an individual, allows him to purchase goods produced by some other individual. Since everyone has a need to purchase goods, they will produce some goods to earn income and buy what they want. So, the product markets will always be in equilibrium.

Show an empirical study that tests the relative inflation and growth rates on the nominal exchange rates.
