¿Creía usted que el colón a 8 pesos colombianos era una devaluación espantosa? Pues el real iraní está mucho, mucho peor, al corte son unos 2200 reales por colón. O un millón de reales por dólar. #IRR

I've put together some insights on the #math of the Internal Rate of Return algorithm (#IRR, or #XIRR). If you're interested in how the algorithm works, including how it calculates net present value, iterates for convergence, and avoids complex numbers, you might find it useful. There's also some basic #Rust and #JavaScript code.

You can find it here: https://weitzel.dev/post/calculating-internal-interest-rate

Racists, apartheid apologists not welcome among liberals

(Today's column, with many comments answered. As if to prove my point, the most upvoted comment is by an apartheid apologist.)

South Africa’s legal system is one of only a handful around the world that treats legal subjects differently based on their perceived race or skin-colour.

Race Law is a public-interest initiative by the South African Institute of Race Relations (IRR) to index all the statutes, regulations, policies, and superior court judgments that perpetuate racialism as a matter of law. It does so through the Index of Race Law.

I’ve not done the HBS one on Striker, but if you’re comparing #irr and #npv of options, focus on discussing the risks of using each approach. IRR is significantly less certain than NPV, given that IRR ignores the discount rate. Use the case data to show the disparity.

I’d stick with your course’s text. If that doesn’t cover it, try this article: https://i-share-uic.primo.exlibrisgroup.com/permalink/01CARLI_UIC/1b4dsmk/cdi_proquest_miscellaneous_1556292829

This is a long shot but does anyone have a good resource for capital budgeting explanations? I'm specifically looking at the case study Stryker corporation in-sourcing pcbs from the Harvard business review #finance #npv #irr #mba
