Total Differential Economics: Small Model Changes
Total differential economics explains how small changes in several variables combine through marginal effects to change an economic model’s outcome.
Implicit Function Theorem Economics: Comparative Statics
Implicit function theorem economics explains how equilibrium comparative statics can be derived locally without solving models explicitly.
Jacobian Matrix Economics: Comparative Statics and Stability
Jacobian matrix economics explains how first-derivative matrices support comparative statics, local solvability, and stability analysis in economic systems.
Hessian Matrix Economics: Curvature and Concavity Tests
Hessian matrix economics explains how second derivatives test curvature, concavity, convexity, and local optima in multivariable economic models.
Bordered Hessian: Second-Order Conditions
Bordered Hessian analysis checks second-order conditions in constrained optimization by testing curvature along feasible directions, not across all possible movements.
Immiserizing Growth: Trade Expansion and Welfare Loss
Immiserizing growth explains how export expansion can reduce welfare when a severe terms-of-trade loss outweighs the gain from higher output.
Specific Factors Model: Short-Run Trade Winners
Specific factors model analysis explains why trade creates clear short-run winners and losers when capital or land is tied to...
Lerner Diagram: Factor Prices in Trade Theory
Lerner diagram analysis shows how goods prices determine wages and capital returns through unit-value isoquants in trade theory.
Factor Price Equalization: Trade and Wage Convergence
Factor price equalization explains why trade can make wages and capital returns converge through goods prices, even when workers and...
