Economic modellers design and estimate mathematical and computational models that represent economic behaviour, policy mechanisms, and market interactions. They evaluate economic shocks, simulate policy scenarios, analyse structural relationships, and forecast macroeconomic or industry-level outcomes. Their work supports governments, research institutes, financial institutions, and international agencies. They use econometrics, optimisation, dynamic modelling, and large datasets to generate insights into inflation, growth, employment, trade, and sector performance. With increasing reliance on predictive analytics and data-driven governance, economic modellers play a critical role in shaping policy and strategic planning.
