In measuring inflation the BLS periodically drops goods from the CPI "formula" or decreases their weight/significance in calculating inflation. For example, if the price of ribeye steaks goes up significantly and people switch to buying chicken, the BLS might substitute a few pounds of chicken for ribeye steaks in the basket of goods. By doing this the BLS increases the significance/weighting of chicken in calculating inflation and decreasing the significance of ribeye steaks. Should we substitute goods in the basket used to calculate inflation? For some background information, the video below discusses this. The video is not intended to be the focus of the discussion. It is intended to illustrate a concern. Your focus should be on determining whether we should substitute goods calculating inflation. Take a position, pro or con
