CBO supports the Congressional budget process by providing the Congress with objective, nonpartisan, and timely analyses of legislative proposals and of budgetary and economic issues. From a macroeconomic perspective, CBO produces work in two areas. First, it provides baseline economic forecasts over 10- and 30-year projection windows. Second, it analyzes the short-term and longer-term effects on the overall economy of some proposed changes in federal tax and spending policies. This presentation describes that work and provides recent examples of forecasts and analysis.
