This article derives the necessary and sufficient conditions for a coinsurance-type insurance policy covering a particular risk to be inferior and to be Giffen. Mossin's decreasing absolute risk aversion assumption for insurance to be inferior is avoided. The result generalizes Hoy and Robson and ...

This sample code is very very basic. I could not imagine what this code has impact on my hardware, having module ESP32-WROOM-32. When running with sleep time 100ms, it's ok. But when decreasing it to 50, 20, 10, 5, 2, 1, 0ms, exceptions happening. 50ms still causes exceptions...
I am working on a problem in which I use ode45 to estimate an equation as x goes from 8 to .0, using 78 steps of the size .1. Y is increasing as x decreases. The equation is: function f=fun2(t,y) f=('-(sqrt(100-t^2)/(t))') ...
