## Introduction

PyEconomics is a versatile and comprehensive library that integrates various
economic and financial models. It is designed to support the development and
analysis of monetary policy rules, exchange rate models, macroeconomic and
microeconomic models, discounted cash flow models, and much more.

## Features

### Current Features

- **Monetary Policy Rules**: Implementation of well-known monetary policy rules.
- **Cache Management**: Efficient caching for API calls to improve performance 
  and reduce redundant data fetching.

### Planned Features

- **Exchange Rate Models**: Models for predicting future exchange rates.
- **Macroeconomic Models**: Comprehensive macroeconomic models.
- **Microeconomic Models**: Detailed microeconomic models.
- **Discounted Cash Flow Models**: Advanced models for discounted cash flow 
  analysis.
- **Financial Models**: Including CAPM and portfolio optimization.
- **Fiscal Policy Models**: Tools to analyze taxation, government spending, and 
  public debt.
- **Additional Economic Models**: Support for behavioral economics, agent-based 
  models, and international trade models.

## Installation

To install PyEconomics, use `pip`:

```sh
pip install pyeconomics
```

### From Source
If you want to install the package from the source code, follow these steps:

1. Clone the repository:

    ```sh
    git clone https://github.com/nathanramoscfa/pyeconomics.git
    ```
   
2. Change to the project directory:

    ```sh
    cd pyeconomics
    ```

3. Install the package:

    ```sh
    pip install .
    ```

## API Key

Some features of PyEconomics require access to the FRED API. To use these 
features, you need to configure your FRED API access. 

A detailed step-by-step guide on obtaining and securely storing your FRED API 
key is available here:

- [FRED API Key Configuration Guide (Markdown)](https://github.com/nathanramoscfa/pyeconomics/blob/main/markdown/FRED_API_CONFIGURATION.md)
- [FRED API Key Configuration Guide (Jupyter Notebook)](https://github.com/nathanramoscfa/pyeconomics/blob/main/examples/api_configuration/fred_api_configuration.ipynb)

## Usage

Here are some basic examples of how to use PyEconomics for calculating and visualizing monetary policy rules.

### Example 1: Calculate Current Policy Rule Estimates

```python
# Import pyeconomics
import pyeconomics as pyecon

# Calculate policy rule estimates
policy_estimates = pyecon.calculate_policy_rule_estimates(verbose=True)
```

### Examples

For more comprehensive examples, refer to the [examples](https://github.com/nathanramoscfa/pyeconomics/tree/main/examples) directory in
the repository.

## Docker

To run PyEconomics using Docker, follow these steps:

1. **Configure the .env File**:
   Create a `.env` file in the root directory of pyeconomics with the following
   content:

    ```env
    FRED_API_KEY=your_fred_api_key_here
    ```

2. **Build the Docker Image**:
   Navigate to your project directory and run the following command to build the
   Docker image:

    ```sh
    docker build -t pyeconomics .
    ```

3. **Run the Docker Container**:
   Run a container from your custom Docker image:

    ```sh
    docker run --env-file .env -p 8888:8888 -it --rm pyeconomics
    ```

   This will start a JupyterLab instance with the specified notebook open.

4. **Access JupyterLab**:
   In the command prompt output, you will see something like this:

    ```plaintext
    To access the server, open this file in a browser:
        file:///root/.local/share/jupyter/runtime/jpserver-1-open.html
    Or copy and paste one of these URLs:
        http://e99fe8b9fbb5:8888/lab/tree/monetary_policy_rules/monetary_policy_rules.ipynb?token=your_token_here
        http://127.0.0.1:8888/lab/tree/monetary_policy_rules/monetary_policy_rules.ipynb?token=your_token_here
    ```

   To open JupyterLab in your browser, hold the CTRL button and click the link 
   starting with: `http://127.0.0.1:8888`. Ignore the other links.

By using Docker, you ensure a consistent environment for running and testing 
PyEconomics.
