Introduction to Dynamic Programming¶

We have studied the theory of dynamic programming in discrete time under certainty. Let's review what we know so far, so that we can start thinking about how to take to the computer.

The Problem¶

We want to find a sequence $\{x_t\}_{t=0}^\infty$ and a function $V^*:X\to\mathbb{R}$ such that

$$V^{\ast}\left(x_{0}\right)=\sup\limits _{\left\{ x_{t}\right\} _{t=0}^{\infty}}\sum\limits _{t=0}^{\infty}\beta^{t}U(x_{t},x_{t+1})$$

Faster Computations with Numba¶

Some notes mostly for myself, but could be useful to you¶

Altough Python is fast compared to other high-level languages, it still is not as fast as C, C++ or Fortran. Luckily, two open source projects Numba and Cython can be used to speed-up computations. Numba is sponsored by the producer of Anaconda more ...

Working with Economic data in Python¶

This notebook will introduce you to working with data in Python. You will use packages like Numpy to manipulate, work and do computations with arrays, matrices, and such, and anipulate data (see my Introduction to Python). But given the needs of economists (and other scientists) it will be advantageous for us to use pandas more ...

Introduction to and using

Python is a powerful and easy to use programming language. It has a large community of developers and given its open source nature, you can find many solutions, scripts, and help all over the web. It is easy to learn and code, and faster than other high-level programming languages...and did I mention it is free more ...
