Definitions of Employed, Unemployedand Unemployment Rate Employed = everyone currently working, including part time workers Unemployed = people looking for work or temporarily laid off from work Unemployment Rate = unemployed labor force Labor force = employed + unemployed Labor force participation rate = labor force population aged 16 and older ECO-1067

  7. Types of Unemployment Frictional Unemployment Structural Unemployment Cyclical Unemployment Other Employment Concepts Natural Rate of Unemployment Full Employment ECO-1067

  8. Phases of the Business Cycle ECO-1067

  9. First look at: Output and its rate of growth Inflation rate Unemployment rate International trade What is macroeconomics? ECO-1067

  10. Gross Domestic Product (GDP) Value of all final goods and services produced within a country in a given time period Real GDP The volume of goods and services produced within a country (i.e. GDP adjusted for inflation, GDP in terms of goods) Economic Growth: Percentage rate of increase of real GDP Measuring Economic Growth ECO-1067

  11. Measuring Inflation Percentage change in the price level GDP deflator Consumer Price Index (CPI) In the Eurozone: Harmonized Index of Consumer Prices (HICP) ECO-1067

  12. Measuring Unemployment Labor force = employed + unemployed Unemployment rate=Unemployment/Labor Force Unemployed: does not have a job and has been looking for one in the past 4 weeks The long term unemployment rate is the share of unemployed persons since 12 months or more in the total number of active persons in the labor market. European Labor Force Survey (LFS) Discouraged workers Labor force participation varies across countries and time ECO-1067

  13. Measuring trade with other countries ECO-1067

  18. Fiscal policies Government spending and taxes Affect economy’s output and price level Stability and Growth Pact National government deficit no larger than 3% of GDP debt-to-GDP ratio of 60% Reduces inflationary pressures (and free-riding) Main purpose of fiscal policy should be stabilization But fiscal policy is main tool left to governments where monetary policy is constrained Evidence that most fiscal policy is pro-cyclical Automatic stabilizer ECO-1067

  19. Other Public Policies Investing in productivity (technology policy) Improving human capital (education) Improving physical capital (infrastructure) External relations (e.g. war expenditures in Iraq) In the EU, these public policies mostly not integrated ECO-1067

  20. Euro: Optimal Currency Area? Common currency: Benefits: elimination of foreign exchange transactions lead to reduction in costs (0.5% of GDP), increased competition The euro is as stable as the best-performing currencies previously used in the euro area countries Costs: loss of monetary policy Optimal currency area (Robert Mundell): Countries have to experience similar shocks If not: countries must have high factor (labor) mobility ECO-1067
