Further estimates on the cost of climate change and global warming

Sea level rise will cause spatial shifts in economic activity over the next 200 years. Using a spatially disaggregated, dynamic model of the world economy, this paper estimates the consequences of probabilistic projections of local sea level changes. Under an intermediate scenario of greenhouse gas emissions, permanent flooding is projected to reduce global real GDP […]

If UFOs are alien beings, are they just doing mood affiliation in visiting us?

Robin Hanson has a long and very interesting blog post on that question.  The point is not to argue that the UFOS are alien beings of some kind, but rather if they were which kinds of theories might help us understand them? Here is just part of Robin’s much longer take: If the main block […]

Research funding sentences to ponder

What happens in the 4 mo between when an NIH grant is submitted and when it is sent to reviewers? This makes applications stale before review. COVID grants being reviewed now were submitted before any phase 3 vaccine results — an eternity ago. Can this lag be shortened? — Craig Wilen (@WilenLab) March 28, 2021 […]

The influence of hidden researcher decisions in applied microeconomics

Another one from the Department of Uh-Oh: Researchers make hundreds of decisions about data collection, preparation, and analysis in their research. We use a many‐analysts approach to measure the extent and impact of these decisions. Two published causal empirical results are replicated by seven replicators each. We find large differences in data preparation and analysis […]

The nature of fame

In the early 1930s, so the story goes, Albert Einstein was in Hollywood, entertaining a visit by a friend, the comedian Charlie Chaplin.  They were enjoying some tarts baked by Elsa Einstein and idly chatting when Einstein’s son turned to Chaplin.  “You are popular,” he said, “because you are understood by the masses.  On the […]

Socioeconomic roots of academic faculty

Using a survey of 7218 professors in PhD-granting departments in the United States across eight disciplines in STEM, social sciences, and the humanities, we find that the estimated median childhood household income among faculty is 23.7% higher than the general public, and faculty are 25 times more likely to have a parent with a PhD. […]

My Conversation with Sarah Parcak, space archaeologist and Egypt lover

Here is the audio, video, and transcript.  Here is part of the summary: She joined Tyler to discuss what caused the Bronze Age Collapse, how well we understand the level of ancient technologies, what archaeologists may learn from the discovery of more than a hundred coffins at the site of Saqqara, how far the Vikings […]

On the GDP-Temperature relationship and its relevance for climate damages

I have worried about related issues for some while, and now that someone has done the hard work I find the results disturbing and possibly significant: Econometric models of temperature impacts on GDP are increasingly used to inform global warming damage assessments. But theory does not prescribe estimable forms of this relationship. By estimating 800 […]

Pandemic sentences to ponder

Of course, there are national health systems in Canada, Mexico, England, and France, among many others, and the uniformity of failure across this heterodox group suggests that structure may have made less of a difference than culture. “One of the common features is that we are a medical-centric group of countries,” says Michael Mina, a […]
