+## Redirects
+
+It is easy to handle redirects on a Hugo website by using the `aliases` parameter within the page front matter. This feature allows you to define old URLs that should redirect to a new page. This is particularly useful when you change the URL structure or move content around in your website, and you want to ensure that visitors are redirected from the old URLs to the new one. This ensures that visitors using the old URLs still find the right content.
+
+The template includes an example showing how to set up redirects using the `aliases` parameter. The redirects are set up in the `/courses/course1/index.md` file. In the preamble, the following snippet of code sets up redirects from old PDF files to the current course page:
+
+```yml
+aliases: 
+    - /courses/course2/slides4.pdf
+    - /courses/course2/slides1.pdf
+    - /courses/course2/slides3.pdf
+    - /courses/course2/slides2.pdf
+    - /courses/course2/notes3.pdf
+    - /courses/course2/notes4.pdf
+    - /courses/course2/ps3.pdf
+    - /courses/course2/ps4.pdf
+    - /courses/course1/quiz1.pdf
+    - /courses/course1/quiz2.pdf
+    - /courses/course2/quiz3.pdf
+    - /courses/course2/quiz4.pdf
+    - /courses/course1/ps1.pdf
+```
+
+Hugo will then automatically generate the necessary redirect HTML pages during the build process. These HTML pages will be stored in the `public` folder. When a visitor navigates to any of the URLs listed in the aliases (such as `baseURL/courses/course2/slides4.pdf`), they will be redirected to the page where the alias is defined (`baseURL/courses/course1/`). 
+
+This method is useful to manage redirects and ensure a seamless user experience when restructuring any part of your website. It is also useful to handle 404 issues since outdated links will automatically point to the correct content, preventing users from landing on the [404 error page](https://pascalmichaillat.org/hugo-website/404/).
+
+---
+
 ## Public folder
 
 The `public` folder contains the fully generated static website files that are ready to be deployed to GitHub Pages. When you run the `hugo` command, Hugo processes your content, templates, and other project files and generates a static website. The resulting output is placed in the `public` folder by default.

This job shortage arises in an economic equilibrium from the combination of some wage rigidity and diminishing marginal returns to labor. In recessions, job rationing is acute, driving the rise in unemployment, whereas matching frictions contribute little to unemployment. Intuitively in recessions, jobs are lacking, the labor market is slack, and recruiting is easy and inexpensive, so matching frictions do not matter much. In a calibrated model, cyclical fluctuations in the composition of unemployment are large.\nFigure 5: Rationing and frictional unemployment in the United States, 1964–2009 Citation Michaillat, Pascal. 2012. “Do Matching Frictions Explain Unemployment?

   "articleBody": " Paper Code and data Abstract This paper aims to compute the unemployment rate $u^\\ast$ that is consistent with full employment in the United States. First, it argues that the most appropriate economic translation of the legal notion of full employment is social efficiency. Here efficiency requires to minimize the nonproductive use of labor—both unemployment and recruiting. The nonproductive use of labor is measured by the number of jobseekers and vacancies, $u + v$. Through the Beveridge curve, the numbers of vacancies and jobseekers are inversely related, $uv = \\text{constant}$. With such symmetry the labor market is efficient when there are as many jobseekers as vacancies ($u = v$), inefficiently tight when there are more vacancies than jobseekers ($v \u003e u$), and inefficiently slack when there are more jobseekers than vacancies ($u \u003e v$). Accordingly, the full-employment rate of unemployment (FERU) is the geometric average of the unemployment and vacancy rates: $u^\\ast = \\sqrt{uv}$. Between 1930 and 2023, the FERU averages 4.1% and is quite stable—it always remains between 2.5% and 6.6%.\nFigure 10A: Unemployment and vacancy rates in the United States, 1930–2023 Figure 11A: Full-employment rate of unemployment in the United States, 1930–2023 Citation Michaillat, Pascal, and Emmanuel Saez. 2024. “u* = √uv.” arXiv:2206.13012v3. https://doi.org/10.48550/arXiv.2206.13012 .\n@techreport{MS24, author = {Pascal Michaillat and Emmanuel Saez}, year = {2024}, title = {$u^* = \\sqrt{uv}$}, number = {arXiv:2206.13012v3}, url = {https://doi.org/10.48550/arXiv.2206.13012}} Related material Presentation slides ",
