Communicating Econometric Results
When you present econometric results to an economic audience, you must focus on clarity, transparency, and economic relevance. Clear communication ensures that your findings are understandable to both specialists and non-specialists. Always use precise language, avoid jargon when possible, and define any technical terms you include.
Transparency is crucial — report your model specification, the estimation method, and any data transformations or adjustments you performed. Include information about sample size, variable definitions, and the economic context of your analysis.
Economic relevance means connecting your statistical results directly to the economic questions or policy issues at hand. Always interpret coefficients in economic terms, such as the effect of a one-unit change in an independent variable on the dependent variable, and relate these effects to real-world implications. Highlight the practical significance of your findings, not just statistical significance.
Use tables and visualizations to summarize key results, but ensure they are easy to read and annotated for your intended audience.

You must address uncertainty, limitations, and responsible communication in your econometric reporting. Always present measures of uncertainty, such as confidence intervals or standard errors, alongside point estimates. Acknowledge model limitations, including omitted variables, potential biases, and the assumptions underlying your methods. Discuss the robustness of your results to different model specifications or sample periods. Be cautious not to overstate the precision or generalizability of your findings—avoid making deterministic claims when results are probabilistic. Responsible communication also means being transparent about the potential policy implications and ensuring that your audience understands both the strengths and the boundaries of your analysis. This approach builds trust and allows economic decision-makers to interpret your results within the appropriate context.
