00:00:03,497 --> 00:00:07,430
- [Alex] ¿Por qué esta casa se vende
en más de $2.5 millones?

2
00:00:08,240 --> 00:00:09,640
O ¿por qué la renta 
de este departamento,

3
00:00:09,640 --> 00:00:12,945
es de más de $3,000 al mes?

4
00:00:13,444 --> 00:00:15,541
¿Es por avaricia? ¿Conspiración?

5
00:00:16,124 --> 00:00:17,134
No.

6
00:00:17,374 --> 00:00:21,600
Se trata de un poderoso concepto,
la elasticidad de la oferta.

7
00:00:22,540 --> 00:00:25,500
Suena complejo,
pero es bastante simple.

8
00:00:26,200 --> 00:00:28,680
En los Estados Unidos
y alrededor rel mundo,

9
00:00:29,165 --> 00:00:30,624
muchas industrias y trabajos

10
00:00:30,624 --> 00:00:33,840
se han estado concentrando
en unas cuantas ciudades dinámicas:

11
00:00:34,300 --> 00:00:37,540
la tecnología de Silicon Valley,
el entretenimiento de L.A.,

12
00:00:38,220 --> 00:00:40,330
y los farmacéuticas en Boston

13
00:00:40,920 --> 00:00:42,215
Así que más y más gente --

14
00:00:42,215 --> 00:00:44,480
quiere vivir 
en estas ciudades dinámicas,

15
00:00:44,760 --> 00:00:47,220
y eso aumenta la demanda de casas.

16
00:00:47,720 --> 00:00:50,816
Y recuerda, ¿qué es lo que pasa
cuando aumenta la demanda?

17
00:00:50,816 --> 00:00:53,060
La curva de la demanda 
se desplaza hacia la derecha,

18
00:00:53,400 --> 00:00:57,880
y los compradores compran más
a cualquier precio.

19
00:00:58,980 --> 00:01:01,590
Esto lleva a un nuevo equilibrio,

20
00:01:01,590 --> 00:01:04,200
con una cantidad mayor vendida
a precios más altos.

21
00:01:05,140 --> 00:01:07,400
Pero, ¿qué incremento será mayor?

22
00:01:07,400 --> 00:01:10,760
¿Cambia la cantidad,
o cambia el precio?

23
00:01:11,720 --> 00:01:13,364
Eso depende

24
00:01:13,364 --> 00:01:17,200
de si la oferta 
es elástica o inelástica.

25
00:01:17,740 --> 00:01:19,717
Si la oferta es elástica,

26
00:01:19,717 --> 00:01:23,201
es decir, que los productores 
producen fácilmente más casas,

27
00:01:23,201 --> 00:01:26,180
entonces la cantidad ofertada
aumentará mucho,

28
00:01:26,640 --> 00:01:29,524
y el precio 
solo aumentará un poco.

29
00:01:30,220 --> 00:01:33,753
Pero si la oferta es inelástica --

30
00:01:34,340 --> 00:01:37,940
eso significa que no es fácil
producir más casas,

31
00:01:38,360 --> 00:01:41,120
y nuestra curva de la oferta
se verá así.

32
00:01:41,940 --> 00:01:43,090
En este caso,

33
00:01:43,090 --> 00:01:46,479
la cantidad ofertada
solo aumentará un poco,

34
00:01:46,823 --> 00:01:49,539
pero el precio aumentará mucho.

35
00:01:51,140 --> 00:01:53,514
Eso sucede cuando

36
00:01:53,514 --> 00:01:56,340


37
00:01:56,800 --> 00:01:58,600


38
00:01:59,783 --> 00:02:05,480


39
00:02:06,060 --> 00:02:10,100


40
00:02:10,680 --> 00:02:13,400


41
00:02:14,180 --> 00:02:15,381


42
00:02:15,381 --> 00:02:17,910


43
00:02:18,460 --> 00:02:20,520


44
00:02:20,520 --> 00:02:22,580


45
00:02:23,400 --> 00:02:26,340


46
00:02:26,680 --> 00:02:30,900


47
00:02:31,440 --> 00:02:32,680

00:02:32,680 --> 00:02:35,526

00:02:35,526 --> 00:02:38,740

00:02:39,520 --> 00:02:41,405


51
00:02:41,655 --> 00:02:44,940


52
00:02:45,530 --> 00:02:48,980


53
00:02:49,440 --> 00:02:51,855

00:02:52,860 --> 00:02:55,474


55
00:02:55,474 --> 00:02:58,300
