On the use of significant digits to convey statistical precision - ASTIER
Most empirical estimates reported in economics are output from software routines. By default, these routines report a fixed number of decimal digits, typically three. We argue this practice represents a missed opportunity to convey statistical precision. We propose a statistical testing procedure that could be easily implemented to avoid both reporting too many digits that lack statistical significance and failing to report precisely estimated digits. Applying our methodology to all articles published in the American Economic Review between 2000 and 2022, we show that over 60% of printed digits for coefficient estimates are not statistically significant at standard levels.

*****************
Ambulatory long-term care (LTC) aims to assist elderly individuals in their own homes. In this study, we analyze the causal impact of the recent increases in provider density due to increasing demand on the quality of ambulatory LTC. We employ data from publicly available transparency reports from 14,000 ambulatory care units in Germany between 2011 and 2019. Our instrumental variable approach exploits information on the nursing home market. Our primary findings indicate that an increase in provider density leads to a decrease in the quality of ambulatory LTC. A potential channel through which this effect may occur is a shortage of qualified nursing personnel. Our conclusion is that a trade-off exists between market entry, which enables better access to professional care, and higher quality. Therefore, we recommend further investment in skilled nursing personnel.

There Goes the Neighborhood: The Contrary Example of Social Housing in Red Vienna, 1923-1933
Between 1923 and 1933, the Social Democratic municipal council of Vienna constructed 335 apartment houses or community buildings (Gemeidenbauten). About 200,000 inhabitants, or 11 percent of the Vienna’s interwar population, occupied roughly 60,000 flats. My claim is that Red Vienna’s investment boom constituted a “big push.” A hub of activity, the Gemiendebauten gave rise to housing externalities. Business enterprises clustered in neighborhoods adjacent to the apartment blocks because they were a source of consumer demand and a readily available labor supply. Workers flocked to the buildings because of the material
and nonmaterial amenities they afforded, and because of their proximity to employment prospects and low priced goods. The quality of neighborhoods improved. The concentration of activity sustained a resilient economic model of growth and redistribution that was cut short by external events.
