0:14 - 0:18- This is a pretty tragic topic and in
some ways it's tough to talk about, but -
0:18 - 0:22let's give it a try. Let's keep in mind
that in the modern world there still -
0:22 - 0:27really is a lot of slavery and many people
are rightfully outraged by this. But the -
0:27 - 0:32question is what to do about it? So in the
1990's, there were humanitarian reformers -
0:33 - 0:38and they went to Sudan and their plan was
to buy slaves and set them free. Now that -
0:39 - 0:43sounds great, what could be better than
setting free slaves? That sounds pretty -
0:43 - 0:48noble, but did it actually stamp out
slavery or did paying slaveholders to -
0:48 - 0:54release these slaves lead to more people
captured? Let's use the economic concept -
0:54 - 0:59of the elasticity of supply to help
understand this better. The problem is -
0:59 - 1:03this, the people trying to free the
slaves, we'll call them the slave -
1:03 - 1:07redeemers, they're also creating
additional demand for slaves. After all, -
1:08 - 1:13they're buying slaves in the market. That
additional demand shifts out the demand -
1:13 - 1:18curve for slaves and that leads to a new
and higher market price. That higher price -
1:19 - 1:23will bring forth additional supply. So
what are the people who round up and -
1:23 - 1:26kidnap the slaves, what are they going to
do? Well, they're going to increase their -
1:27 - 1:30operations. They're going to have more
raids and they're going to take more -
1:30 - 1:36people into slavery. We can already see
there's at least a possibility that buying -
1:37 - 1:40the slaves and setting them free will be
counterproductive because we haven't -
1:40 - 1:45managed to stamp out all of slavery, what
we've done is set some people free but -
1:45 - 1:49actually give those kidnappers, those
people in the middle, we've increased -
1:49 - 1:54their incentives to bring more people into
slavery. And therein lies the potential -
1:54 - 1:59for an even greater tragedy. The concept
of elasticity in economic terms that -
1:59 - 2:04refers to how responsive is quantity
supplied when market price changes. -
2:04 - 2:09It's going to help us understand how much
a slave redemption program will increase -
2:09 - 2:14the number of people who end up captured
by slave raiders. Inelastic supply means -
2:14 - 2:19that even a much higher price doesn't
result in a much larger quantity supplied. -
2:19 - 2:24In that case, even if the price of slaves
went up by a lot, not that many additional -
2:24 - 2:28people would be captured. That's the
better case scenario. It also means the -
2:28 - 2:33price of slaves will go up and stay high
because the off setting supply response is -
2:33 - 2:37weak and it's not pushing that market
price back down again. Again that's the -
2:38 - 2:42better case scenario. It means that in the
long run the redeemers are doing more to -
2:42 - 2:47limit slavery than to encourage it. But,
however, let's say the supply curve is -
2:47 - 2:52more elastic, that means a flatter curve
and it means the quantity supplied to the -
2:52 - 2:58market will increase a lot with the higher
price. In that case, it's easier to find -
2:58 - 3:02more people to enslave. Then as a result
of the boost in demand from the -
3:02 - 3:08humanitarian redeemers, a lot more people
will end up captured and enslaved and then -
3:09 - 3:13the total number of people captured as
slaves is going up quite a bit. And you -
3:13 - 3:17have to wonder in that case are these
slave redemption programs really a good -
3:17 - 3:25idea? So what's the answer? It's genuinely
hard to say whether the supply of slaves -
3:25 - 3:31is elastic or inelastic, but we can look
at price as a possible indicator of which -
3:31 - 3:35scenario is more likely to hold. We know
that in the early years of slave -
3:35 - 3:40redemption there was a noticeable increase
in the price of slaves and that could be -
3:40 - 3:45evidenced of a fairly inelastic supply
curve. However, over time the price of -
3:46 - 3:51slaves has fallen and that could indicate
greater elasticity of supply in the longer -
3:51 - 3:56run. That makes sense but the suppliers
are usually more responsive to an increase -
3:56 - 4:01in price as they have more time to adjust.
For instance, they can hire more people -
4:01 - 4:06and expand their operations.
So this evidence overall suggests that -
4:06 - 4:11perhaps the program has become less
effective over time and perhaps today it -
4:11 - 4:16may actually be counterproductive and be
increasing the burden of slavery. In other -
4:16 - 4:21words, good intentions aren't always
enough. If someone comes along and puts an -
4:22 - 4:26apparently good idea on the table, we
still need to think through it's -
4:26 - 4:28unintended consequences.

- Title:
- Elasticity and Slave Redemption
- Description:
-
Beginning in 1993, Sudan entered into a civil war, with one of the worst parts being that many people were kidnapped and sold into slavery. Humanitarian groups traveled to Sudan to redeem slaves by buying them out of slavery. Is this good policy? Did it work out, or make it worse? Let’s use elasticity to analyze the situation.
