In his podcast, "50 Things That Made The Modern Economy" Tim Harford looks to explain multiple different inventions, how they were used, and the impacts in which they made on society. In the eight episodes that were elaborated and in which notes were taken on, Harford explained how the Wardian case, tampons, tulips, dams, auctions, algorithms, slot machines, and the Gutenberg press all made an impact on some sort of economical level, whether it be a policy, marketing strategies, new ways to make money, examples of economic crisis, and even the addictivity of some money making inventions. The speaker of this podcast is Tim Harford, he is a widely renowned author, broadcaster, and journalist who is most known for his book “The Undercover Economist” and has won multiple awards for his authorship and is known for breaking down complex modern economy issues into simple engaging ways for audiences--whom of which not all have college degrees in economics--to understand the topics Harford discusses and writes about in his works. In the case of this podcast, Harford's main purpose is to explain and discuss complex economic topics that each product or invention brings up, but to do so in a way for his audience to grasp it. He wants to make it not simple, but understandable and engaging. Harford's audience is most likely people who are interested in economics, or things that made the modern economy (hints the name), but not all of these people have insight to complex economic topics, and because of this Harford explains these topics with an assumption of base level knowledge from his audience, but also with great simplicity, still arriving at the core problem or effect of each product. The context of this podcast is that Tim Harford is a well known and renowned economist who has won multiple awards and has an OBE. That is the context behind the author, but in his podcast, Harford often gives context behind each individual item or product he is discussing, showing where it came from, how it came to be, and even a fun story of someone using the same invention. Harford's exigency is that the modern economy is changing every single day, and there is little time to simply sit around and watch, he suggests that the human race needs to learn from their past mistakes in the economic world and move on with new ideas and new inventions, in a way that does not hinder or harm the economy, but instead only makes it stronger.
