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.
Every business day, big capitalist institutions depend on having access to unbiased economic statistics. It's time for them to step up and help protect the B.L.S. and other statistical agencies from Trump's encroachments.
