1. GDP and Its Components (1). Visit the website of the Bureau of Economic Analysis (BEA) at http://www.bea.govational/index.htm. Click on "Gross Domestic Product (GDP)". Historical data on realominal GDP can be found in two excel files: Current-dollar and "real" GDP (Excel) and Percent change from preceding period (Excel). (a) Plot graphs separately using nominal GDP, real GDP, nominal GDP growth rate, real GDP growth rate. (b) Based on your graphs, can you roughly identify the periods of expansions (boom) and recessions (depression)? (2). Click on "Balance of Payments". Historical data on international trade can be found in the excel file: U.S. Trade in Goods and Services, 1992-present. (a) Plot the evolution of US exports, imports, and current account balances.
