Governor runs your economy on the Carlin–Soskice three-equation model — the one macroeconomics is taught from in upper-year university courses.
IS — Demand. The dearer money is, the less a country spends and invests — but with a lag. Add to that the exchange rate, the government's budget, and how freely banks are allowed to lend.
PC — Inflation and unemployment. An overheated economy pushes prices up faster than a slump pulls them back down. And down is the hard direction: wages are almost never cut.
MR — The monetary policy rule. The game derives the best rate not from a curve, but from what costs you more — missing the inflation target, or unemployment you didn't have to have.
You set the nominal rate. The real price of money is what's left once expected inflation is taken out — and what people and markets expect depends on how far they trust you. Hit the target and credibility accumulates; miss it several quarters running and it crumbles, and the very same rate starts working noticeably weaker. The rate has a floor. If the central bank answers to the government, inflation drifts upward on its own: markets price in the abuse before it happens. Unemployment is tied to output, and banks add their own markup on top of your rate — borrowers pay more than you announced.
Out of your decisions a long-run picture assembles itself: economic growth (Solow), equilibrium unemployment, inequality (Gini), public debt, the exchange rate and the trade balance — and financial bubbles that inflate and burst if nobody is watching them.
1931, the golden fetters — hold the gold standard, or let the currency go so the economy can breathe.
1971, Camp David — close the gold window, or defend Bretton Woods with reserves.
1979, Volcker — crush inflation with the rate, or take the road of price controls.
2008, the Lehman weekend — put a shoulder under the banking system, or let it fall.
2021, "is inflation transitory?" — wait the price spike out, or hit it early.
The 1929 crash, three waves of bank panics, a war in which the Fed holds rates wherever the Treasury needs them, Bretton Woods, the OPEC embargo, the Volcker disinflation, Black Monday, the Asian crisis, the dot-com bust, 2008, the pandemic and the inflation of 2021–2022 — all of it arrives on schedule. Only one question stays open: what will you do about it?
A full tutorial and a short one, to get the basic economic concepts and the links between them.
The state of the economy is drawn as a city on the world map. Buildings rise and multiply as the country grows richer; traffic in the streets shows how hard the economy is running; the city's colours warm up in an overheat and go cold in a slump; cranes work when money is cheap and the future looks good. You will see a crisis in the skyline before you open a chart.
Around it — a world map with historical borders by era and up to 24 rival countries, each with a central bank of its own. They trade with you the more willingly the closer and richer you are; tariffs and trade wars tear those ties apart. A separate mode, off by default, switches on spheres of influence: blocs, satellites, and debt dependency between countries.
If you would rather have numbers than pictures, there is the terminal: tables, charts, and a breakdown of every move in inflation — by cause, with figures. Plus the influence map: 106 variables of the model and 276 links between them, all on one screen.
Gather famous economists into an association of your own.
Once a year the Economic Association meets and takes your policy apart. You appoint the Chair — and with them a school of thought: it grants your economy one permanent bonus and one permanent penalty.
From two players — over Steam or a local network. Each has their own country and a full copy of the model; after every turn the worlds are reconciled, so your surplus is somebody else's deficit. Credit to a neighbour is a lever too, and debtors know it.
No toy models, no random numbers standing in for an economy, no "correct" playthrough, and no story that will pull you out of a stagflation you arranged yourself. There is a model, a hundred years of history, and the price of a mistake you set for yourself.
