Economics
Economic models are often taught as diagrams. Here you build them as working spreadsheets: change a tariff, a policy rate or a savings rate and watch the model respond. Each step is checked, which makes it much easier to see what an assumption does and why economists disagree about it.
The 6 courses cover international trade, macroeconomic models with multipliers, AD–AS and IS–LM, money creation and central-bank rules, labour markets and inequality measures, and growth accounting with the Solow model. Business-oriented economics is also covered in the business category.
EconomicsShow with real numbers who gains from trade, and who wins and loses when a tariff or quota is imposed, with every cell checked as you go.
EconomicsSolve classic macro models cell by cell and watch what fiscal and monetary policy do to output and prices, with every cell checked as you go.
EconomicsFollow money from a central bank balance sheet through banks to prices in one fictional economy: money aggregates, deposit creation and the money multiplier, MV = PY, a rule-based policy rate, real rates and the policy stance, seigniorage and an inflation-target scorecard, with every cell checked as you go.
EconomicsMeasure jobs, wages and income distribution from fictional survey data and see how policies change the numbers: labour-force rates, worker flows and steady-state unemployment, a wage floor with surplus and deadweight loss, real wages and the labour share, quintiles, Lorenz curves, the Gini coefficient and a redistribution scenario, with every cell checked as you go.
EconomicsSimulate how saving, population and productivity drive long-run income, and compare countries fairly: growth rates and doubling times, Cobb–Douglas, a Solow simulation, the golden rule, growth accounting, convergence, PPP and a development index, with every cell checked as you go.
EconomicsModel how real people choose: hyperbolic discounting, loss aversion, probability weighting, anchoring and defaults, with every cell checked as you go.
Yes. The courses complement introductory and intermediate university courses by letting you compute the models yourself.
No. The models are built with spreadsheet formulas. Some advanced courses mention calculus results but do not require you to derive them.
Each course is a single purchase of $9.99. That covers every lesson and lab, the final exam and the certificate, with no subscription and nothing that renews.
