Take the controls of the economic machine.

Every pilot reads the instruments before touching the controls. Learn the three gauges the whole world watches — output, unemployment and inflation — how each is actually measured, how they move together, and why headlines get them wrong.

Over months and quarters, demand runs the show. Build the goods market and meet the multiplier, see how the central bank sets the interest rate, then bolt the two markets together into IS-LM — the machine economists still reach for first when the economy lurches.

Push output above its potential and something has to give: wages, then prices. Meet the labor market that anchors the natural rate of unemployment, the Phillips curve that links slack to inflation, and the IS-LM-PC model that shows how — and how painfully — the economy returns to normal.

In the long run, business cycles are ripples on a rising tide. Discover the facts of growth — why living standards multiplied tenfold in a century — then build the Solow model to see what saving can and cannot buy, and why technology is the only engine that never stalls.

No economy is an island. Open the borders and every answer changes: exchange rates join interest rates on the dashboard, imports leak from the multiplier, and monetary policy gains a powerful new channel. Learn interest parity, the open-economy IS-LM, and why fixed exchange rates can end in tears.

Now you take the controls. See how expectations make policy a conversation with the future, how government debt snowballs or melts depending on r versus g, how modern central banks actually operate — targets, rules, the zero lower bound, QE — and what to do when the machine truly breaks.
