NOTE The Broken Window

1
00:00:00.000 --> 00:00:16.640
We're ready for part two of our series, and I'm here with Thomas DiLomenzo from Loyola

2
00:00:16.640 --> 00:00:17.640
University.

3
00:00:17.640 --> 00:00:23.840
We're going to get into the very heart of the book, Economics Among Us and Now, here

4
00:00:23.840 --> 00:00:24.840
with you.

5
00:00:24.840 --> 00:00:27.920
But I'd like to just read this one sentence and ask you to defend it here.

6
00:00:27.920 --> 00:00:38.920
He says, it is often sadly remarked that the bad economists present their errors to the public better than the good economists present their truths.

7
00:00:38.920 --> 00:00:39.920
What do you think about that?

8
00:00:39.920 --> 00:00:44.920
We were talking about the broken window fallacy, I assume, in that passage.

9
00:00:44.920 --> 00:00:54.920
You can't really be an economist or think like an economist and let you understand the broken window fallacy, I think, which is the essence of opportunity cost.

10
00:00:54.920 --> 00:01:00.480
And one way I explain it to my classes is, you know, I teach at a Catholic university

11
00:01:00.480 --> 00:01:06.600
and we're always encouraging students to engage in some sort of community service.

12
00:01:06.600 --> 00:01:12.800
So I tell the class that the economics department has our own version of community service.

13
00:01:12.800 --> 00:01:16.600
We're going to buy each of you an aluminum baseball bat and we're all going to march

14
00:01:16.600 --> 00:01:21.000
down North Charles Street, which is the main street north and south in Baltimore.

15
00:01:21.000 --> 00:01:23.920
We're going to bash in all the windows of the cars all the way down.

16
00:01:23.920 --> 00:01:27.920
and it's a job creation program. That's our community service, I tell them.

17
00:01:27.920 --> 00:01:31.920
And then I asked them, what kind of jobs do you think we'll create in the city of Baltimore?

18
00:01:31.920 --> 00:01:34.920
Will it reduce unemployment? Will it reduce poverty?

19
00:01:34.920 --> 00:01:39.920
And they scratched their heads for a minute, and they said, well, glass repair, garbage collection,

20
00:01:39.920 --> 00:01:46.920
extra private security guards, and I write down on a blackboard a list of all the jobs we're going to create.

21
00:01:46.920 --> 00:01:50.920
And then I asked them, well, why don't we burn down some buildings on the way?

22
00:01:50.920 --> 00:01:54.920
We'll eliminate poverty altogether, won't we?

23
00:01:54.920 --> 00:01:58.920
And then they start thinking about it, well, wait a minute, there's something wrong here about this.

24
00:01:58.920 --> 00:02:10.920
And so, if they've already read sort of the theory of opportunity costs, they'll catch on that, of course, that's what's seen, those jobs are seen, the glass repairmen and all that.

25
00:02:10.920 --> 00:02:22.920
What is not seen is all the resources that had to be transferred from somewhere else or reallocated and jobs destroyed there so that we can fix up the glass and hire the security guards and so forth.

26
00:02:22.920 --> 00:02:33.920
And so the whole key to thinking like an economist really is to think about what is not seen as well as what is seen in the words of the immortal Friedrich Bastiat.

27
00:02:33.920 --> 00:02:48.920
Well, Annette, it seems like it would be something easy to understand, once you hear the story of the broken window, and to understand the fallacy, and perhaps you were following it. If that's so, why is it so persistent?

28
00:02:48.920 --> 00:02:54.840
I think economic miseducation has a lot to do with it. I think economists, especially

29
00:02:54.840 --> 00:03:01.280
including academic economists when they teach, are so enamored with mathematics and model

30
00:03:01.280 --> 00:03:08.760
building that they ignore or downplay really the basic fundamental truths of economics,

31
00:03:08.760 --> 00:03:15.400
like opportunity cost, because it's so mundane. You can't really model it or can't express

32
00:03:15.400 --> 00:03:45.400
in Mathematics that well, and they tend to forget about it. And then students who take classes, they might learn these sophisticated models, but they don't learn really basic economics. And that's why the Austrian School of Economics has always been so appealing to me. It's always been rooted in understanding how the economic world works, as opposed to showing off your math skills. And I think economic miseducation is the main reason why so many people and members of the public

33
00:03:45.400 --> 00:03:52.720
So, opportunity costs are always invisible, so they don't show up in the economic data.

34
00:03:52.720 --> 00:03:53.720
Right.

35
00:03:53.720 --> 00:03:54.720
Not always.

36
00:03:54.720 --> 00:03:56.920
Sometimes, some of them do.

37
00:03:56.920 --> 00:04:02.200
And this makes it less interesting than for an empirical economist.

38
00:04:02.200 --> 00:04:03.200
Right.

39
00:04:03.200 --> 00:04:10.440
On the empirical side, the old joke about the economist looking for his watch across the

40
00:04:10.440 --> 00:04:15.320
street when he knew he lost it on the other side of the street, and when he's asked,

41
00:04:15.320 --> 00:04:20.320
So why are you looking for your watch over there when you know you lost it over here and he says the light is better over there?

42
00:04:20.320 --> 00:04:29.320
That's very true about economists because when they undergo their research, if they do empirical research, they're limited by what kind of data they can get.

43
00:04:29.320 --> 00:04:37.320
Even though there are very important questions that need to be asked and addressed that you just can't measure empirically all the time.

44
00:04:37.320 --> 00:04:44.320
And so they tend to ignore these things and so there's a lot of truth to that old joke about the economist and his watch.

45
00:04:44.320 --> 00:04:50.320
So it has the causes, chapter two, after he explains the lesson, he calls it the blessings of destruction.

46
00:04:50.320 --> 00:05:00.320
Right, but he talks a lot about war and the idea that things such as war can be good for the economy, war prosperity, you heard that phrase.

47
00:05:00.320 --> 00:05:08.320
And of course some people do become wealthy through war, the people who sell munitions to the government and so forth, that's what's seen, you see that.

48
00:05:08.320 --> 00:05:13.520
but then once again what is not seen is all the resources are taken out of the

49
00:05:13.520 --> 00:05:18.360
pockets of the taxpayers to pay for it and also another slightly more

50
00:05:18.360 --> 00:05:23.600
sophisticated part of this is that you know the market system is one big

51
00:05:23.600 --> 00:05:29.120
network that displays the international division of labor and it's peaceful and

52
00:05:29.120 --> 00:05:32.960
cooperative we work together to produce goods and services or buy and sell from

53
00:05:32.960 --> 00:05:36.920
one another war is just the opposite war is blowing things up and destroying

54
00:05:36.920 --> 00:05:59.920
and so the very idea that war can produce prosperity in any sense is absurd on the face of it and Henry Haslip explains that as simply and straightforwardly as anybody I've ever read in just a couple of paragraphs really and von Mises does a great job of that also in Human Action in his chapter on war and the economy.

55
00:05:59.920 --> 00:06:05.920
It's also true with natural disasters. We played this game on the Mises blog anytime.

56
00:06:05.920 --> 00:06:11.920
There was a fire or a flood or anything. We didn't see how many days it would be before a professional economist makes a statement.

57
00:06:11.920 --> 00:06:15.920
Yeah, we always end up digging up an article from the New York Times or the LA Times,

58
00:06:15.920 --> 00:06:20.920
so we have some pseudo-economist saying, well, the bright side is that it's good for the economy.

59
00:06:20.920 --> 00:06:27.920
In fact, there was an earthquake in Southern California yesterday as we sit here at the Mises Institute on July 30th.

60
00:06:27.920 --> 00:06:34.920
And sure enough, I bet tomorrow if we do a web search, we'll find a statement like this.

61
00:06:34.920 --> 00:06:40.920
Thank goodness in this time of the housing crisis and the subprime crisis and we're in a recession,

62
00:06:40.920 --> 00:06:45.920
God sent us an earthquake in Southern California. Somebody's going to say something like that.

63
00:06:45.920 --> 00:06:51.920
And when they do, I think we should send that person a copy of economics in one lesson.

64
00:06:51.920 --> 00:06:54.920
Whatever reporter we discover says that thing.

65
00:06:54.920 --> 00:07:04.420
So do you find that your teaching in your introductory classes consists of just that today applying this lesson?

66
00:07:04.420 --> 00:07:11.420
Oh yeah, not just introductory classes. I taught a new course I put together called the Political Economy of War.

67
00:07:11.420 --> 00:07:20.420
And the very first week of readings involved the Broken Window Fallacy and Ludwig von Mises on War and the Economy,

68
00:07:20.420 --> 00:07:38.180
Do you think this new edition will be helpful to you?

69
00:07:38.180 --> 00:07:44.700
Oh yes, it's a beautiful edition and it's priced very well and congratulations on being

70
00:07:44.700 --> 00:08:06.700
I'm sure I'll be buying box loads of them, because I always have, for 20 years I've been buying copies of Economics in One Lesson, because as an economics professor I run into people all the time who ask me, what one book can I read that's not too complicated and technical, a lot of math, and understand economics, and Economics in One Lesson is that book.

71
00:08:06.700 --> 00:08:08.700
Well thank you very much, Dr. Ludwig.

72
00:08:14.700 --> 00:08:28.700
The Theory of Money and Credit
