Measuring Value
Must measure value of all products and services, not numbers of products and services
Ex- one country produced 5 million paperclips; the other produces 3 million computers, which one has a greater GDP?
![Page 6: The branch of economic theory dealing with the economy as a whole and decision making by governments](https://reader038.vdocuments.us/reader038/viewer/2022110210/56649e7a5503460f94b7b78b/html5/thumbnails/6.jpg)
Measuring Final Goods and Services Must not double count goods;
instead measure the final product Ex- are you going to measure the
number of bike tires and the number of bikes made if you’re only going to sell the bikes?
