Biased estimator - The inpact on business

I think I got the technical part of an unbiased and biased estimator but, what if I don’t check or overlook the numbers and end up using a biased estimator in my analysis. I wonder, which are the consequences to the business?
I mean, I’ll draw the wrong conclusion and, ultimately, I’ll make my company loses money?


Let’s say you make a model to predict the price of… toys based on different parameters. If the model is biased and predicts a high value, you are not going to sell any toy. Or if the model predicts a really low value, you can sell but you don’t get a revenue

That’s why you have to use an error metric
