What predicts professional philosophers’ views?

The entire piece is interesting, but this segment caught my eye in particular: Additionally, they found that being more politically right-leaning was associated with several philosophical views, such as theism, free will libertarianism, nonphysicalist views in philosophy of mind, and the correspondence theory of truth. Here is more from Justin Weinberg.  Belief in hard determinism, by the way, is correlated with lower levels of happiness. I say this all boosts Strauss in relative status.  It...

The American economy circa 2021

Spending on cars and trucks is 15.1 percent higher than it would have been on the 2019 trajectory; spending on furnishings and durable household equipment is 16.6 percent higher; and spending on recreational goods is a whopping 26 percent higher. Altogether, durable goods spending is running $348.5 billion higher annually than it would have been in that alternate universe, as Americans have spent their stimulus checks and unused travel money on physical items. The housing sector is...

Facts about biomass

The carbonaceous winners are plants, which make up about 80 percent of all biomass on Earth. Bacteria comes in second at 13 percent and fungus is third at just 2 percent. Of the 550 gigatons of biomass carbon on Earth, animals make up about 2 gigatons, with insects comprising half of that and fish taking up another 0.7 gigatons. Everything else, including mammals, birds, nematodes and mollusks are roughly 0.3 gigatons, with humans weighing in at 0.06 gigatons. The research appears in The...

Are Covid travel bans counterproductive for emerging economies?

Sometimes, yes: …two opposing forces constitute the first-order determinants of total infections at any point in time.  On one hand, the longer a travel ban lasts, the less time community transmission exists in the rural sink.  Ceteris paribus, this will decrease rural infections.  On the other hand, the longer the restrictions remain, the longer migrants are contained within a hotspot where infection rates are rapidly increasing.  Consequently, the probability that migrants are...

How well did Medicare pay-for-performance work?

For pain management, and pain management, only, it seems it worked just fine: Medicare uses a pay-for-performance program to reimburse hospitals. One of the key input measures in the performance formula is patient satisfaction with their hospital care. Physicians and hospitals, however, have raised concerns regarding questions related to patient satisfaction with pain management during hospitalization. They report feeling pressured to prescribe opioids to alleviate pain and boost satisfaction...

Newark fact of the day

Newark Police officers did not fire a single shot during the calendar year 2020, and the city didn’t pay a single dime to settle police brutality cases. That’s never happened, at least in the city’s modern history. At the same time, crime is dropping, and police recovered almost 500 illegal guns from the street during the year. Here is the longer story. The post Newark fact of the day appeared first on Marginal REVOLUTION.

Do career disruptions matter for the top five percent?

How resilient are high-skilled, white collar workers? We exploit a uniquely comprehensive dataset of individual-level resumes of bank employees and the setting of the Lehman Brothers bankruptcy to estimate the effect of an unanticipated shock on the career paths of mobile and high skilled labor. We find evidence of short-term effects that largely dissipate over the course of the decade and that touch only the senior-most employees. We match each employee of Lehman Brothers in January 2008 to...

How to extract information from on-line reviews, or why Star Wars is still a thing

Online reviews promise to provide people with immediate access to the wisdom of the crowds. Yet, half of all reviews on Amazon and Yelp provide the most positive rating possible, despite human behaviour being substantially more varied in nature. We term the challenge of discerning success within this sea of positive ratings the ‘positivity problem’. Positivity, however, is only one facet of individuals’ opinions. We propose that one solution to the positivity problem lies with the...

Facts about Nigerian-Americans

Second-generation black Americans have been inadequately studied in prior quantitative research. The authors seek to ameliorate this research gap by using the Current Population Survey to investigate education and wages among second-generation black Americans with a focus on Nigerian Americans. The latter group has been identified in some qualitative studies as having particularly notable socioeconomic attainments. The results indicate that the educational attainment of second-generation...
