Econometrics I

📊 Econometrics: Uses & Key Topics

Econometrics blends statistics, mathematics, and economics to analyze and quantify economic relationships. It's not just theory—it's about testing ideas with real-world data.

🔧 Main Uses:

  • Policy Evaluation: Measuring the impact of economic policies like subsidies or tax reforms.
  • Forecasting: Predicting future trends such as inflation, unemployment, or GDP growth.
  • Causal Analysis: Identifying cause-and-effect in economic behavior (e.g. Does education lead to higher income?).
  • Market Research: Estimating consumer demand and firm production efficiency.

📚 Core Topics:

  • Regression Analysis (linear & nonlinear): The backbone of econometric modeling.
  • Time Series Analysis: Studying data over time to capture trends and seasonality.
  • Panel Data Models: Combining time-series with cross-sectional data for richer insights.
  • Simultaneous Equation Models: Handling interdependent economic variables.
  • Instrumental Variables & Causality Tests: Tackling endogeneity and getting cleaner causal effects.
  • Error Terms & Assumptions: Understanding residuals, heteroscedasticity, autocorrelation, etc.
