latex-econ-model_skill

Overview

This skill generates well-formatted LaTeX for economic models, producing academic-quality notation, environments, and common macros. It targets utility maximization, equilibrium conditions, dynamic programming, and game-theoretic setups so you can paste directly into a paper or lecture note. Outputs follow standard economics conventions and include helpful packages and custom commands.

How this skill works

I ask a few questions to understand the model type (static, dynamic, game, or general equilibrium), agent types, constraints, and whether proofs or only the setup are needed. I then produce a structured LaTeX document or snippet with Environment, Preferences/Technology, Constraints, Equilibrium concept, and Solution sections. The output includes recommended packages, consistent notation, labeled equations, first-order conditions, and optional boxed key results or proofs.

When to use it

• Writing the theory section of a journal article or working paper
• Formalizing an economic model before simulation or calibration
• Preparing lecture notes with clear, reproducible equations
• Typesetting optimization problems, Euler equations, and Bellman equations
• Drafting proofs or propositions tied to model solutions

Best practices

• Use the provided package set (amsmath, amssymb, amsthm, mathtools, bm, dsfont) for robust typesetting
• Define custom macros for repeated symbols (\E, \R, \pd{}, \argmax) to ensure consistency
• Label major equations with \label{} and reference via \eqref{} for cross-references
• Align multiline derivations with align and alignat, and box central results with \boxed{}
• Keep notation consistent across sections: time subscript t, agents i, parameters Greek (\alpha, \beta, \delta)

Example use cases

• Two-period consumer optimization with budget constraint and Euler equation, including boxed result and short proof
• Firm dynamic programming: Bellman equation, FOCs, and steady-state condition
• Simple Nash game: players, strategies, payoff functions, and best-response conditions
• Small open-economy general equilibrium: households, firms, market clearing, and equilibrium prices
• Lecture handout snippets: ready-to-compile LaTeX blocks for classroom use
