# Wasserstein Index Generation Model: Automatic Generation of Time-series Index with Application to Economic Policy Uncertainty

## TL;DR

This paper introduces the Wasserstein Index Generation model (WIG), a new method for automatically creating sentiment indices, demonstrated through its application to generate an Economic Policy Uncertainty index.

## Contribution

The paper presents a novel automatic index generation method using Wasserstein distance, applied specifically to economic policy uncertainty measurement.

## Key findings

- Successfully generated an EPU index using WIG
- Demonstrated effectiveness of WIG in sentiment index creation
- Provides a new tool for economic policy analysis

## Abstract

I propose a novel method, the Wasserstein Index Generation model (WIG), to generate a public sentiment index automatically. To test the model`s effectiveness, an application to generate Economic Policy Uncertainty (EPU) index is showcased.
