<u>One of the most famous law codes that have been preserved along history</u> is actually <u>the Code of Hammurabi</u>, which he used to rule Babylon. Nowadays it is exhibited at Louvre, in Paris.
The Code of Hammurabi dates back to 1754 BC. He used a large carved stone to list a set of rulings, mainly punishments, which adjusted with different intensity levels the principle <em>"an eye for an eye, a tooth for a tooth" . </em>The code includes the first manifestations of contract law, property law or family law and also regulations concerning transactions or social responsibilities.
The Great Depression caused serious inflation, so the answer is "Prices". Hope that helps!
