Economists are like meteorologists or climate scientists. They study the system, build models, run experiments, and forecast outcomes. They can often tell you WHY inflation is happening, what factors matter most, and what the likely effects of certain policies will be.
Policymakers are like the engineers with the thermostat. They actually have their hands on the controls like interest rates, government spending, taxes, and regulations. But their tools are slow, blunt, and often politically constrained.
An engineer has precise tools and a closed system (turn knob -> air temp changes in minutes). A policymaker has crude tools and an open system full of humans who REACT to the tools themselves. Economists can tell policymakers “If you turn the knob this far, you’ll probably cool things down by this much, but only after 6–18 months, and if no other shocks hit in the meantime.”. Policymakers then face trade-offs: you can bring inflation down, but you might cause a recession, raise unemployment, or trigger political backlash.
Economists explain the system. Policymakers steer it. But the steering wheel is loose, the brakes are slow, and the passengers in the backseat keep fighting over which way to turn and how fast to go and how loud the music should be and where they actually wanna stop for lunch.
