Goods Market (Keynesian Cross), Production Function, and Labour Market can be analysed simultaneously. Demand-driven model with stable disequilibria. Shows the steady-state values of the economy for your choice of aggregate demand, production function and labour supply. Output gaps, unemployment and required fiscal policies are also calculated.
Classic damper for excessive hopes in monetary policy. Adjustable inflation expectations and natural unemployment prevent a lasting influence of monetary "tricks" on the economy. You can prescribe five inputs and analyse how short-term real effects (along a short-term Philips curve) dissolve.
The interest rate as a determinant of the exchange rate. Enter the domestic and foreign interest rate as well as the spot rate and obtain the forward rate and the swap rate for the covered interest rate parity (CIP), and the expected rate of change of the exchange rate for the uncovered interest rate parity (UIP) respectively. Appreciation and depreciation expectations are also displayed.
The price level as a determinant of the exchange rate. You will receive the purchasing power parity exchange rate e (PPP) after inserting price levels (absolute PPP) or inflation rates (relative PPP). Specify an actual exchange rate (not equal to e PPP) and the program also calculates appreciation/depreciation expectations as well as the arbitrage of goods.
The classic of international economics. In addition to the usual results such as comparative cost advantages and transformation curves, here you can quickly discover by changing the world market price why trade is potentially conflict-laden (although "everyone wins") and which five different scenarios should be distinguished.
The AS curve as a price level-based Phillips curve. For a demand shock, P and Y are calculated at five points in time to be able to highlight three cases: 1. "Keynesian sticky prices", 2. standard, 3. "rational expectations". Furthermore, you can interactively analyse the back and forth between price changes and adjustments of price expectations.
The AS curve as a price level-based Phillips curve. For a supply shock, P and Y are calculated at five points in time. Stabilization policies are faced with a trade-off between stabilizing the output or the price level. The alternative scenario "variable full employment output" is also presented.
Is a free trade area advantageous over a unilateral tariff policy? In this 3-country model, you can analyze trade creation and trade diversion. If you switch off the 3rd country, you can work with a standard trade model that allows a welfare comparison "import or export tariffs vs. free trade".
