Distinction between microeconomics and macroeconomics Key macroeconomic Terms

GDP, Gross Domestic Product, is a measure of the total output produced by an economy in a given year. Inflation is the rate of change in the average price level. Inflation of 2% indicates that prices have risen by 2% during the previous month.
Key Macroeconomic Terms

Unemployment is the number of individuals seeking work but do not currently have a job. The current account of the balance of payments is the difference between exported and imported goods and services. Interest rates are the price of money and set by a central bank. The government deficit is the difference between government spending and tax receipts.
Economic Growth, Inflation and Unemployment in India

GDP- $796.1 billion (2006 est.) GDP - real growth rate:8.5% (2006 est.) Unemployment rate:7.8% (2006 est.) Population below poverty line: 25 % (2002) Household income or consumption by percentage share:lowest 10%: 3.5% highest 10%: 33.5% (1997) Inflation: Above 7%

Total Expenditure

Total expenditure is simply all separate sources of spending within the economy. It includes consumption by households, investment by firms and public spending by the government. Net exports are also included in it. If any of these increase, then total expenditure increases and the flow of goods and services should increase to match the increased demand.
Aggregate Demand
Total expenditure representing consumption, plus investment, plus government spending plus net exports is in fact aggregate demand.
Average Price Level

The average price level is the average price of goods and services in an economy. The change in the average price level is a measure of inflation. The benefit of looking at the relationship between aggregate demand and inflation is that control of inflation has become a key aspect of modern macroeconomic policy.
Aggregate Demand and Inflation

AD = C+I+G+NZ Where C = consumption, I = investment, G = government spending and NZ = net exports.

Aggregate Supply and Inflation

Difference between nominal and real values. Nominal prices and wages are not adjusted for inflation. Real prices and wages are adjusted for inflation. If I earn $100 a week and if inflation is 2%, then what is my real wage?
Aggregate Supply and Inflation

When wages adjust fully for inflation a firm is not affected. But if wages lag behind inflation then the economy would have a positive sloping supply curve for inflation.

Inflation and Deflation
Inflation is a measure of how fast prices are rising. So, an increase in the price level is inflation and a decrease in the price level is deflation.
