Recon - Computational Tools for Economics

This package aims to provide undergraduate students and professors realiable ways of computing and exploring canonical models in economics. It creates a rich enviroment for comparative statics, visualization of results and better understanding of model outcomes.


You can install the latest version of Recon by running:


## or directly from CRAN


Which should return something similar to:

Features by theme

To get a general view of what's implemented in Recon directly from R you can run:

help(package = Recon)

Economic Growth

  • Steady state solution to the model presented in Solow (1956)
  • Steady state solution to the model presented in Mankiw, Romer and Weil (1992)

Cobb-Douglas Functions

  • Computing Cobb-Douglas functions with 2 inputs
  • Computing Cobb-Douglas functions with $n$-inputs


  • Grid generating function, so one can map results easily

Game Theory

  • Finds the Pure Strategies Nash Equilibrium of a 2 person simultaneous game
  • Finds the Mixed Strategies Nash Equilibrium of a 2 person simultaneous game, for 2x2 pay-off matrices

Imperfect Competition

  • Solution to a Cournot Duopoly Model, with linear and non-linear cost and demand curves
  • Solution to a Stackelberg Duopoly Model, with non-linear cost curves
  • Solution to Monopoly Profit Maximization

Upcoming Features and Suggestions

Feel free to ask/suggest a model for implementation. If you want to implement one youself, fork this repo and then do a pull request with your new functions. After reviewing, you'll be credited and your functions will be part of Recon. Features that are currently under work:

  • Solution to a Bertrand Duopoly Model with differentiated goods
  • Solution to a Cournot Oligpoly with n firms and homogenous cost functions
