Presentation
This slide deck outlines the models CBO uses to assess the budgetary effects of alternative economic scenarios such as those presented in CBO’s Current View of the Economy in 2023 and 2024 and the Budgetary Implications (November 2022).

Summary
CBO's analysis of economic uncertainty was conducted in three main steps:
- Preliminary economic projections provided central estimates for each variable;
- 100 simulations of the rates of unemployment, inflation, and interest were jointly estimated around the central estimates, reflecting asymmetric dynamics and relating the variables through an expectations-augmented Phillips curve and an inertial Taylor rule; and
- Forecasts conditional on those rates were estimated using symmetric distributions in which economic output and other variables were synchronized with the simulations of unemployment, inflation, and interest rates.
This document focuses on how CBO took 100 simulations of the variables generated in those three steps and assessed their implications for the federal budget.
