LaTeX Economic Model Writer

Purpose

This skill helps economists write and typeset economic models in LaTeX with proper mathematical notation, consistent formatting, and academic conventions. It covers utility maximization, equilibrium conditions, dynamic programming, and game theory models.

When to Use

\documentclass{article} \usepackage{amsmath, amssymb, amsthm} \usepackage{mathtools} % Theorem environments \newtheorem{definition}{Definition} \newtheorem{proposition}{Proposition} \newtheorem{lemma}{Lemma} % Custom commands for economics \newcommand{\E}{\mathbb{E}} % Expectation \newcommand{\R}{\mathbb{R}} % Real numbers \newcommand{\pd}[2]{\frac{\partial #1}{\partial #2}} % Partial derivative \begin{document} \section{A Simple Consumer Problem} \subsection{Environment} Consider a consumer who lives for two periods, $t \in \{1, 2\}$. The consumer has preferences over consumption $c_t$ represented by the utility function: % \begin{equation} U(c_1, c_2) = u(c_1) + \beta u(c_2) \end{equation} % where $\beta \in (0,1)$ is the discount factor and $u(\cdot)$ is strictly increasing and strictly concave. \subsection{Constraints} The consumer earns income $y_1$ in period 1 and $y_2$ in period 2. She can save at gross interest rate $R = 1 + r$. The budget constraints are: % \begin{align} c_1 + s &= y_1 \label{eq:bc1}\\ c_2 &= y_2 + Rs \label{eq:bc2} \end{align} % where $s$ denotes savings. Combining \eqref{eq:bc1} and \eqref{eq:bc2} yields the intertemporal budget constraint: % \begin{equation} c_1 + \frac{c_2}{R} = y_1 + \frac{y_2}{R} \equiv W \end{equation} \subsection{Optimization Problem} The consumer solves: % \begin{equation} \max_{c_1, c_2} \quad u(c_1) + \beta u(c_2) \quad \text{s.t.} \quad c_1 + \frac{c_2}{R} = W \end{equation} \subsection{Solution} The Lagrangian is: % \begin{equation} \mathcal{L} = u(c_1) + \beta u(c_2) + \lambda\left(W - c_1 - \frac{c_2}{R}\right) \end{equation} First-order conditions: % \begin{align} \pd{\mathcal{L}}{c_1} &= u'(c_1) - \lambda = 0 \\ \pd{\mathcal{L}}{c_2} &= \beta u'(c_2) - \frac{\lambda}{R} = 0 \end{align} Combining these yields the \textbf{Euler equation}: % \begin{equation} \boxed{u'(c_1) = \beta R \cdot u'(c_2)} \end{equation} \begin{proposition}[Consumption Smoothing] If $\beta R = 1$, then $c_1^* = c_2^*$ (perfect consumption smoothing). \end{proposition} \begin{proof} When $\beta R = 1$, the Euler equation becomes $u'(c_1) = u'(c_2)$. Since $u$ is strictly concave, $u'$ is strictly decreasing, which implies $c_1 = c_2$. \end{proof} %==================================== \section{A Firm's Dynamic Problem} %==================================== Consider a firm that maximizes the present value of profits: % \begin{equation} \max_{\{k_{t+1}, n_t\}_{t=0}^{\infty}} \sum_{t=0}^{\infty} \beta^t \left[ F(k_t, n_t) - w_t n_t - I_t \right] \end{equation} % subject to the capital accumulation equation: % \begin{equation} k_{t+1} = (1 - \delta) k_t + I_t \end{equation} The Bellman equation is: % \begin{equation} V(k) = \max_{k', n} \left\{ F(k, n) - wn - k' + (1-\delta)k + \beta V(k') \right\} \end{equation} \end{document}
