Weeks ago, we considered the world’s countries populations on the horizontal axis and the number of their COVID-19 cases on the vertical as the points in blue, below. Several countries formed Upper COVID Infection Limit (those with white triangles inside blue circles). The regressed blue line through these points described 98.5% of their variation. By […]
In an earlier post, we examined the recreational pot tax structure. Using US-only data, we discovered that at its frontier, a Laffer Curve formed that described the maximum amount of tax revenues possible given specific tax rates. Here we entertain other authorities taxing legal recreational pot. Added to the blue points forming a limit is […]
In 1968, Rocky Bleier joined the Pittsburg Steelers. After the season, once drafted, he volunteered for duty in Vietnam. When he came #price to the team camp in 1972, he posted a 4.6-second 40-yard dash. With part of his right foot blown off. His previous best was 4.8. What’s the value of added speed for […]
If you’re into the game, you probably have a rough idea about how the National Football League assigns values to its players. A little analysis provides unexpected insights. Each dot in A and B denotes one of 106 NFL wide receivers in 2019. A’s plane shows the value the league assigns to them. It’s a […]
The Laffer Curve is the relationship between tax rates and revenues. For income, taxes of 0% or 100% produce no tax revenue. Maximum tax receipts lie in-between. The study of this phenomenon has mainly been theoretical. The recent rush of states legalizing recreational marijuana gives us a real-world example. In 2014, Colorado and Washington legalized […]
In the last post, we discovered an Upper Infection Limit for COVID-19. Its cases positively correlate to density (as expected) and per capita GDP (not expected). After Mike McRae wrote that “COVID-19 Deaths Are Being Linked to Vitamin D Deficiency (Health, May 1, 2020),” I decided to dig deeper. I found COVID-19 has a Lower […]
Many variables are at work in the COVID-19 pandemic. Analyses in 4 dimensions help visualize them. In markets, such structures use prices as objective functions. As the virus seeks to replicate, its goal is to infect hosts. We see each infection as a case. At right, we plot countries’ populations against their COVID-19 cases on […]
How do businesses’ pay to give workers a short stroll to amenities? Using open-source data, we find companies buy easy access to nearby banks, stores, and cafes as they pay for office space and zip codes. In A, we see LA commercial real estate prices rise with square footage and nearby household income (P-values 3.82E-16 […]
Aiming at and missing is much the same for battles and marketplaces. We account for inaccuracies in the same way. In A, a pilot sits in a Caudron G.3, an Allied surveillance plane in WWI. Note the fuselage aft of his seat. Scenario B recounts a different G.3 pilot on an observation sortie, climbing out […]
Businesses frequently set price goals. What does it mean not to hit them? In A, we predict 1, the price of a barrel of oil. When the forecast date arises, the actual price, 2, varies, resulting in a one-dimension Error Line. We know by how much we missed, but nothing else. B shows us what […]
