Chapter 2

Since economy can be call a science, but the issue calling economy a sciences is: in any other science we can set up experiments to test out theories and gather data we can not do that with an economy that is why rudimentary systems are set to explain and test some theory but at the same time a lot of info has to be filter out for example on the trade examples we were only dealing with 2 traders and 2 commodities to trade.
something that i belived before reading this was that people get pay base on the status of the economy of the country. for example when i come down to mexico i see people as productive as in the USA but the difference is that prices down there a cheaper so i just assumed that it was because the relationship between what they need to live off. Now that i read the chapter is raises the question if they are as productive as up here why do they make less?
