New in JOEG: Off-the-job learning in cities.
#econsky

Off-the-job learning in cities
Abstract Cities are characterized by high skill levels and workers improve their skills through learning. This article presents novel stylized facts on learning behavior and cities. I use Japanese survey data that provide distinctively rich first-hand information about the frequency, purpose, and subject of off-the-job learning. First, people engage in learning more frequently in denser cities. Second, people in denser cities are more likely to learn to gain new employment or cultivate themselves. Third, while cities tend to facilitate learning of skills required in skill-intensive sectors, what people learn depends on the local demand for skills.

A key challenge for BLS is adequate funding for data collection and modernization. During my tenure I tried to identify the causes. One person told me, ‘your problem is that while BLS has no enemies you also have no friends’ meaning no powerful interest groups advocating for economic data.

The latest JEP has an extraordinary set of papers on the economics of housing. My favorite? The one showing that most people incorrectly believe that increasing housing supply won't lower housing costs. Subsidizing home-buying is popular even though it raises costs. 🤦

With government statistics, it's pretty simple. If you liked the February, March, and April numbers, then you have to accept all the next ones, too. They are produced in the exact same way, it's what the computer spits out, based on the inputs provided. You do not get to cherry pick your stats.
