Economics Solver

The Economics Solver works numeric and graphical problems from principles and intermediate economics. Micro: price, income, and cross elasticity by midpoint or point method, equilibrium from supply and demand equations, the effect of a tax or price control, consumer and producer surplus, total, average, and marginal cost, profit maximisation where MR equals MC, perfect competition and monopoly outcomes, game theory payoff matrices. Macro: GDP by expenditure and income, real versus nominal, growth rates, CPI and inflation, unemployment rates, the spending and money multipliers, and simple monetary and fiscal policy effects. Production possibilities and comparative advantage, budget constraints and indifference curves, and the Keynesian cross are worked with the numbers or the equations given, and the graph is described in words.

Type the problem with the numbers: "price rises from $4 to $5 and quantity demanded falls from 100 to 80, elasticity", "Qd = 100 - 2P and Qs = 20 + 2P, find equilibrium and the surplus", "nominal GDP 21 trillion, deflator 105, real GDP". Say midpoint or point method if the course requires one. Photos of problem sets and of tables work. Set Answer form to decimal for numeric answers or both if you want the expression kept. For a table-based problem, paste the table with its headers. For a comparative-advantage problem, give the output or the hours for each producer and good. For a policy question, state the tax, subsidy, price ceiling, or price floor value.

Output: the value first, then the formula, the substitution, the arithmetic, and one line on what the number means: elastic or inelastic, shortage or surplus, expand or contract. Graph-based questions describe the curves and the shift in words with the new equilibrium computed. The working is shown so you can check it. For time value of money, bonds, and accounting entries, use the Finance & Accounting Solver. For the calculus behind marginal quantities, the Derivative Calculator shows the differentiation. A follow-up can rerun the elasticity by the other method, shift a curve and recompute equilibrium, or compute deadweight loss from a tax. Each formula is written in symbols first, then with the numbers, then with the interpretation, which is the layout most problem sets expect.
