字幕依据：Jacob: Welcome to Crash Course Economics. And today we're going to do something a little different. We're going to explore one moment in history in depth. We're going to talk about how the 2008 Financial Crisis happened and the government response to it in the United States. GPOv72Awo68@0:01
字幕依据：But big money, global investors didn't want to just buy up my mortgage, and Stan's mortgage. It's too much hassle to deal with us as individuals. Instead, they bought investments called mortgage backed-securities. Mortgage backed-securities are created when large financial institutions securitize mortgages. GPOv72Awo68@2:21
字幕依据：Eventually, some institutions even started using what are called predatory ending practices to generate mortgages. They made loans without verifying income and offered absurd, adjustable rate mortgages with payments people could afford at first, but quickly ballooned beyond their means. GPOv72Awo68@3:38
字幕依据：Actually, let's go to the Housing Bubble. Rapid increases, driven by irrational decisions. Well, this was a bubble, and bubbles have an annoying tendency to burst. People just couldn't pay for their incredibly expensive houses, or keep up with their ballooning mortgage payments. GPOv72Awo68@4:52
字幕依据：There was another financial instrument that financial institutions had on their books that exacerbated all of these problems--unregulated, over-the-counter derivatives, including something called credit default swaps, that were basically sold as insurance against mortgage backed securities. GPOv72Awo68@5:55
字幕依据：All the world’s financial elite are flying in to come together for the annual conference of the International Monetary Fund and the World Bank. These two institutions were established at the end of World War II to promote smooth economic growth and to resolve crises quickly as they occur. O2pD_y61jx4@0:10
字幕依据：Are policymakers better able to keep pace with the financial markets today? It’s surprising in retrospect how little was learned from the Asian financial crisis in 2008. I mean, in effect, much of the memory of 97, 98 was buried or it was somehow declared exotic. O2pD_y61jx4@3:46
字幕依据：We mustn’t forget that in 1993 the World Bank published a hugely influential book that stirred up a great deal of controversy: The East Asian Miracle. So if the World Bank, a highly influential organisation, labels an entire region like this, then investors will be keen to get into that region. O2pD_y61jx4@6:02
