Inequality and Optimal Monetary Policy in the Open Economy

CODES FOR "INEQUALITY AND OPTIMAL MONETARY POLICY IN THE OPEN ECONOMY" BY SUSHANT ACHARYA AND EDOUARD CHALLE FOR PUBLICATION IN THE JOURNAL OF INTERNATIONAL ECONOMICS
************************************************************************
The codes are written in MATLAB and run in MATLAB 4.2.0.2806996. MATLAB is not freeware and can be obtained from https://www.mathworks.com/products/matlab.html
The code also requires the MATLAB Symbolic Math Toolbox Version 24.2

Instructions:
1. Run pics_for_paper.m to generate Figures 1,2,3 and 4.

Other functions called by the above scripts:
a) makesteady.m : this function computes the steady state of the Ramsey plan in the HANK economy.
b) make_steady_RANK.m : this function computes steady states of the Ramsey plan for the RANK benchmark.
c) optdynamics.m : this function computes the optimal dynamics in response to an aggregate shock shock in the HANK economy.
d) opt_dynamics_RANK.m : this function computes the optimal dynamics in response to an aggregate shock shock in the RANK economy.
e) pricestab.m : this function coputes the dyamics in response to shocks in HANK when monetary policy inefficiently implements price stability.
F) colors.m : this function assigns names to returns RGB tuples adapted from % http://en.wikipedia.org/wiki/List_of_colors, and is used in plotting curves in all figures.

************************************************************************
本套代码基于MATLAB编写，可在MATLAB 4.2.0.2806996版本环境下运行。MATLAB并非免费软件，可通过https://www.mathworks.com/products/matlab.html获取。
本代码同时需要安装MATLAB符号数学工具箱（MATLAB Symbolic Math Toolbox）24.2版本。

使用说明：
1. 运行pics_for_paper.m以生成图1、图2、图3与图4。

上述脚本所调用的其他函数如下：
a) makesteady.m：该函数用于计算异质性代理人新凯恩斯（HANK）经济中拉姆齐计划的稳态。
b) make_steady_RANK.m：该函数用于计算代表性代理人新凯恩斯（RANK）基准模型下拉姆齐计划的稳态。
c) optdynamics.m：该函数用于计算异质性代理人新凯恩斯（HANK）经济中针对总冲击的最优动态路径。
d) opt_dynamics_RANK.m：该函数用于计算代表性代理人新凯恩斯（RANK）经济中针对总冲击的最优动态路径。
e) pricestab.m：该函数用于计算当货币政策低效实现价格稳定目标时，异质性代理人新凯恩斯（HANK）经济中针对各类冲击的动态路径。
f) colors.m：该函数为返回的RGB元组分配名称，改编自https://en.wikipedia.org/wiki/List_of_colors，用于所有图表的曲线绘制。
