0:00:06.372,0:00:09.415 If you tried to pay for something[br]with a piece of paper, 0:00:09.439,0:00:11.350 you might run into some trouble. 0:00:11.374,0:00:15.311 Unless, of course, the piece of paper[br]was a hundred dollar bill. 0:00:15.335,0:00:18.890 But what is it that makes that bill[br]so much more interesting and valuable 0:00:18.914,0:00:20.769 than other pieces of paper? 0:00:20.793,0:00:23.421 After all, there's not much[br]you can do with it. 0:00:23.445,0:00:25.055 You can't eat it. 0:00:25.079,0:00:26.556 You can't build things with it. 0:00:26.580,0:00:28.272 And burning it is actually illegal. 0:00:29.089,0:00:30.460 So what's the big deal? 0:00:30.770,0:00:32.991 Of course, you probably know the answer. 0:00:33.015,0:00:35.410 A hundred dollar bill[br]is printed by the government 0:00:35.434,0:00:37.460 and designated as official currency, 0:00:37.484,0:00:39.511 while other pieces of paper are not. 0:00:40.384,0:00:42.332 But that's just what makes them legal. 0:00:42.356,0:00:45.261 What makes a hundred dollar bill[br]valuable, on the other hand, 0:00:45.285,0:00:47.546 is how many or few of them are around. 0:00:48.031,0:00:51.472 Throughout history, most currency,[br]including the US dollar, 0:00:51.496,0:00:53.499 was linked to valuable commodities 0:00:53.523,0:00:55.352 and the amount of it in circulation 0:00:55.376,0:00:58.372 depended on a government's gold[br]or silver reserves. 0:00:59.166,0:01:01.930 But after the US abolished[br]this system in 1971, 0:01:01.954,0:01:05.762 the dollar became[br]what is known as fiat money, 0:01:05.786,0:01:08.197 meaning not linked[br]to any external resource 0:01:08.221,0:01:11.159 but relying instead solely[br]on government policy 0:01:11.183,0:01:13.620 to decide how much currency to print. 0:01:13.644,0:01:16.582 Which branch of our government[br]sets this policy? 0:01:16.606,0:01:19.572 The Executive, the Legislative,[br]or the Judicial? 0:01:19.596,0:01:22.044 The surprising answer is:[br]none of the above! 0:01:22.068,0:01:26.801 In fact, monetary policy is set[br]by an independent Federal Reserve System, 0:01:26.825,0:01:28.552 or the Fed, 0:01:28.576,0:01:32.595 made up of 12 regional banks[br]in major cities around the country. 0:01:32.619,0:01:33.930 Its board of governors, 0:01:33.954,0:01:36.979 which is appointed by the president[br]and confirmed by the Senate, 0:01:37.003,0:01:38.097 reports to Congress, 0:01:38.121,0:01:41.595 and all the Fed's profit[br]goes into the US Treasury. 0:01:41.619,0:01:43.572 But to keep the Fed from being influenced 0:01:43.596,0:01:45.762 by the day-to-day[br]vicissitudes of politics, 0:01:45.786,0:01:49.238 it is not under the direct control[br]of any branch of government. 0:01:49.262,0:01:52.678 Why doesn't the Fed just decide[br]to print infinite hundred dollar bills 0:01:52.702,0:01:54.227 to make everyone happy and rich? 0:01:54.251,0:01:56.871 Well, because then the bills[br]wouldn't be worth anything. 0:01:56.895,0:01:58.996 Think about the purpose of currency, 0:01:59.020,0:02:01.832 which is to be exchanged[br]for goods and services. 0:02:01.856,0:02:04.047 If the total amount[br]of currency in circulation 0:02:04.071,0:02:08.794 increases faster than the total value[br]of goods and services in the economy, 0:02:08.818,0:02:10.675 then each individual piece will be able 0:02:10.699,0:02:13.342 to buy a smaller portion[br]of those things than before. 0:02:13.366,0:02:15.204 This is called inflation. 0:02:15.228,0:02:16.652 On the other hand, 0:02:16.676,0:02:18.438 if the money supply remains the same, 0:02:18.462,0:02:20.594 while more goods[br]and services are produced, 0:02:20.618,0:02:22.564 each dollar's value would increase 0:02:22.588,0:02:24.817 in a process known as deflation. 0:02:24.841,0:02:26.616 So which is worse? 0:02:26.640,0:02:27.823 Too much inflation 0:02:27.847,0:02:31.133 means that the money in your wallet today[br]will be worth less tomorrow, 0:02:31.157,0:02:33.156 making you want to spend it right away. 0:02:33.180,0:02:37.013 While this would stimulate business,[br]it would also encourage overconsumption, 0:02:37.037,0:02:39.875 or hoarding commodities,[br]like food and fuel, 0:02:39.899,0:02:41.620 raising their prices 0:02:41.644,0:02:44.481 and leading to consumer shortages[br]and even more inflation. 0:02:45.704,0:02:49.096 But deflation would make people[br]want to hold onto their money, 0:02:49.120,0:02:51.009 and a decrease in consumer spending 0:02:51.033,0:02:52.567 would reduce business profits, 0:02:52.591,0:02:55.930 leading to more unemployment[br]and a further decrease in spending, 0:02:55.954,0:02:58.227 causing the economy to keep shrinking. 0:02:58.251,0:03:01.894 So most economists believe that[br]while too much of either is dangerous, 0:03:01.918,0:03:06.806 a small, consistent amount of inflation[br]is necessary to encourage economic growth. 0:03:07.787,0:03:10.234 The Fed uses vast amounts of economic data 0:03:10.258,0:03:13.597 to determine how much currency[br]should be in circulation, 0:03:13.621,0:03:15.575 including previous rates of inflation, 0:03:15.599,0:03:17.881 international trends,[br]and the unemployment rate. 0:03:18.739,0:03:20.443 Like in the story of Goldilocks, 0:03:20.467,0:03:22.325 they need to get the numbers just right 0:03:22.349,0:03:24.921 in order to stimulate growth[br]and keep people employed, 0:03:24.945,0:03:27.670 without letting inflation[br]reach disruptive levels. 0:03:27.694,0:03:29.044 The Fed not only determines 0:03:29.068,0:03:32.219 how much that paper[br]in your wallet is worth 0:03:32.243,0:03:34.962 but also your chances[br]of getting or keeping the job 0:03:34.986,0:03:36.325 where you earn it.
